Benjamin Tennyson was a really normal kid; he went to school (didn’t like it), played video games (Sumo Slammers is his favorite) and got bullied. When summer vacation started Ben with on a road trip with his Grandfather Max Tennyson and his cousin Gwendolyn Tennyson. Meanwhile a ship being piloted by an alien named Xylene was being attacked by another alien being named Vilgax. Xylene was carrying an alien device called the Omnitrix, although we do not learn of Xylene's involvement with the Omnitrix until season 2. The Omnitrix has the power to turn any being into any other type pf life form who’s DNA is stored inside it. Xylene was forced to send the Omnitrix and herself down to Earth in an escape pod. She sent the Omnitrix to Earth but she was attacked getting into her own pond and wound up going to the arctic where she went into hibernation. Ben found the pod, once he did the Omnitrix latched onto his wrist and he couldn’t get it off. While trying to take it off he accidentally transformed into a fire powered alien he would name Heatblast. After starting a fire by accident he told Max and Gwen what happen and Max (suspiciously) said he was an alien. While Ben was wondering how to turn back into a human the Omnitrix began to flash red and beep. He was soon turned back into his human form. Meanwhile, the heavily injured Vilgax is forced to spend some time in his regeneration pod to recover. He sends one of his robot probes to follow the last trace of the Omnitrix and retrieve it.
Back on Earth, Ben was playing with the Omnitrix and had become a giant dog-like creature. This form had no eyes but could see using echolocation and was agile and strong. Ben was soon attacked by the probes and he destroyed some but was about to be killed after he turned back human if not for Gwen beating it with a stick. Vilgax then sent a giant robot drone after Ben and it began attacking a trailer park. Ben then became a crystal like humanoid that was invulnerable and can turn its body it crystal like weapons. Ben would soon meet many enemies going on the road such as Doctor Animo, a mad geneticist who creates mutated animals and wants to take over the world, the Circus Freak Trio, Sixsix and more. Ben later meet a young mutant sociopath named Kevin 11. Kevin has the power to absorb different types of energy and use it as he sees fit. At first Ben and Kevin got along but Ben soon saw Kevin’s true side and during a fight Kevin found he could absorb the energy of the Omnitrix and partially become some of the alien life forms in the Omnitrix. Kevin was going to use his power to get revenge on some kids who bothered him but was stopped by Ben. Kevin tried to steal more of the Omnitrix’s power but couldn’t handle it and was blasted into a bridge that collapsed on top of him. He did survive however and had absorbed the powers of the watch. Gwen also had fun as a hero ( Lucky Girl) when she came across one of the Charms of Bezel, which gave her the power of incredibly good luck and first meet recurring villain Hex who wanted all of the charms. Gwen was forced to destroy them however so Hex couldn’t have them. During one adventure were Ben was stuck in his Grey Matter form he was captured by an alien hunting nerd named
Howell Wayneright. Wayneright had intended to hand Ben over a group called The Forever Knights and their leader Enoch. Grandpa and Gwen tracked Ben down and with some help from the reformed Wayneright were able to free Ben. The Forever Knights would become recurring villains in the series. Ben would battle many more aliens until Vilgax appeared on Earth in a new stronger body while the gang was in Washington D.C. Grandpa was acting suspicious the whole time and trying to keep Ben from fighting Ben would still battle some of Vilgax’s drones until he fought Vilgax himself. Vilgax was too strong for Ben and showed that he new a great many of the Omnitrix’s secrets, as he was able to turn Ben back into a human. Vilgax was angered that a child was giving him so much trouble. Vilgax captures Ben and Grandpa and Gwen enter a secret lair in Mount Rushmore to gather weapons to free Ben. Ben and his family defeat Vilgax and Ben tells grandpa he has some questions.
Grandpa reveals that he was once part of a group called the Plumbers. They were an agency that fought against alien and supernatural forces and that Vilgax was and old enemy of his. They also meet and old Plumber friend of Max’s he has been setting the aliens that they Plumbers captured free so he can make a profit of there recapture. He was accidentally trapped in the Null Void, which is another dimension that Plumbers sent their prisoners to. Ben’s aliens are soon seen all over the country reeking havoc and stealing what ever they pleas. It turns out to be Kevin who has gain the power to turn any to any one of Ben’s aliens without the Omnitrix for however long he wants but he can’t change back and blames Ben for his condition. Because of the things Kevin has done Ben’s aliens are being hunted by soldiers being lead by Lieutenant Steel. Kevin soon turns into and an amalgam of all of Ben’s aliens and can’t turn back into his human self at all or there individual forms. He is soon shot off a bridge by an energy cannon fired by Steel’s men and falls into the ocean. Ben also gains a new alien he names Cannonbolt that can roll into a super hard ball that can spin incredibly fast when fighting a giant tick monster trying to drain Earth of its’ life force. This new form is essential for it’s defeat as Ben destroyed the Tick from the inside. Kevin later appears alive and well. He attacks Ben but isn’t quite as effective as even though he has all ten of Ben’s powers plus his own, Ben describes them as being only one tenth the strength of his powers. The two are soon captured by an alien named Slix Vigma who captures different species and makes them fight. The two are forced to team up but soon are at odds once they defeat their Slix who turns out to be a robot that is one with the whole ship they are on. After they defeat Vigma and many of the other prisoners escape Kevin turns on Ben. Ben transforms into Cannonbolt because Kevin has seen him and doesn’t know how his powers work. Ben is also helped by Technorg another alien who Ben saved from Kevin and helps Ben due to a code of honor. As Ben escapes Technorg stays with Kevin intending to make their stay on the ship as painful as possible. Ben would soon meet a group of alien heroes called The Galactic Enforcers when they helped him stop Sixsix and his new ally Vulkanus. He would transform into a new alien called Wildvine when battling an evil giant fungus. The gang would also fight The Forever Knights again when they tried to find an ancient powerful sword called the Sword of Ekchuah. Max becomes obsessed with finding the sword, but is relieved when he sees that the sword has become brittle and became dust once taken from its resting place. Gwen would also become Lucky Girl again after finding the Keystone of Bezel, which increased her natural abilities. She also fought Hex and his niece Charmcaster. Hex wanted to use the keystone to bring back the other charms, but was stopped by Gwen, Ben and Grandpa. Ben would soon lose control of his alien form of Ghostfreak. Ghostfreak revealed that his species consciousness lives in every piece of DNA and that he was trapped in the Omnitrix and wanted out. Once escaped he took on his true form but was revealed to be weak against sunlight and needed to merge with Ben to fix that. He used the Freakshow Trio to try and due it, but was destroyed by Ben. Kevin would soon return to Earth after finding Vilgax frozen in ice in space. Meanwhile Ben had accidentally activated a master control on the Omnitrix that allowed him to be any of his forms with a thought, could go to one form to the next, and wasn’t timing out. Ben was giving the two of them a hard time, but grandpa didn’t think he could stop the two soon he went to get the Null Void projector which he kept with him after they left D.C. He tried to trap the two in the Null Void, but Ben got sucked along as well and it was up to Gwen to save him. Vilgax took her and Ben gave him the Omnitrix, but not before Ben reset it back to the way it was, but Vilgax assured him he could reset the control, but was double-crossed by Kevin. However Ben and Gwen was able to leave the two trapped in the Null Void and brought the Omnitrix out with them.
Back To The Future
Ben and Gwen soon meet future versions of themselves from twenty years. In the future Ben had become Ben 10,000 learning everything about the Omnitrix, Ben had become overly obsessed with fighting crime. He began never regaining his human form always “going hero”. Gwen led the younger versions of themselves to the future under the pretense that Ben 10,000 needed help. but the future Gwen now a sorceress brought there younger selves to the future to help lighten Ben up. They would also fight an evil hypnotist named Sublimino and face off against Charmcaster again trying to switch bodies with Ben. They also face off against an alien werewolf who is stilling parts to build a satellite and Ben discovers he can absorb new aliens into the watch by letting them touch it when he absorbs the alien werewolf. They also fight an alien mummy planning to steal an alien mineral called Corrodium that is a powerful energy source, but can mutate other beings. Ben stops the mummy, but not before absorbing it’s DNA into the Omnitrix. The Tennysons soon find out that a space shuttle has been delayed due to purple lightning, the same kind that appeared when the werewolf and mummy showed up. They soon find that the alien werewolf has freed the mummy and that they are working with an evil alien version of Frankenstein named Vicktor and that there plan is to resurrect there true leader Ghostfreak. After bringing back Ghostfreak the Tennysons find out that Ghostfreak plans to use the Corrodium to block out the sun and mutate the Earth so he can rule. However after absorbing Vicktor’s DNA the family is able to stop Ghostfreak’s plan and destroy him once again by exposing him to sunlight while they were in space. When Ben returns to Earth he sees that the Omnitrix has absorbed Ghostfreaks DNA again and that his return will eventually come. The gang soon meets Xylene after her and one of Vilgax’s older drone’s are awakened. Xylene informs Ben that she was sending the Omnitrix to grandpa when Ben found it and that he and Xylene were lovers when they he was younger. She helps them battle the drone and reveals a new alien to Ben. She leaves the planet after kissing Grandpa goodbye when he wouldn’t go with her to space.
Ben is soon trapped in a dream world by Enoch, but with help from Gwen and Grandpa escape and trap Enoch in his own dream world. As punishment for failing the Forever King reveals himself and orders Enoch be left in his dream. Ben soon find another new alien in the Omnitrix that can copy itself and uses it to stop Doctor Animo. They soon face Hex again who has aged and is looking for he Fountain of Youth. Ben and Grandpa are exposed and become younger. While as a toddler, Gwen pushes Ben into having a temper tantrum as a baby Heatblast, causing him to evaporate the fountain of youth. During the evaporation, Hex apparently swallowed a large amount of the water and was turned into an infant. When the battle is over the fountains guardian, who is Ponce De Leon, tells the two they you have to keep drinking the water to stay young and they should age soon. This episode takes place in St. Augustine, Fl. Hex is last seen being taken care of by Charmcaster saying she is the boss now. Ben also attends a wedding between Joel, a member off an all-Plumber family and his bride to be Camille, a member of an alien race called Sludgepuppies. Ben has to stop Camille’s family from stopping the wedding. The Tennyson’s also get the Rustbucket back from some road pirates called the Road Crew. Ben soon helps out some mutant brothers named Gaterboy and Porcupine out of their life of crime.
Secret of the Omnitrix
During a battle with Dr. Animo, Ben Tennyson's destruction of the scientist's "DNA bomb" accidentally sets off a self-destruct protocol in the Omnitrix. Its activation alerts Tetrax (known as Hoverboard in "Hunted"), who travels to Earth in order to retrieve Ben. He explains the situation to Ben, who hasn't figured out the meaning of the countdown. He leaves Gwen and Grandpa Max behind, not wanting the latter to be recognized during their trip. Gwen sneaks on board anyway.
Using the advanced medical equipment on board his ship, Tetrax finds the DNA signature of the Omnitrix's creator, Azmuth, and tracks him to a prison facility called Incarcecon. After staging a breakout, they free a female Chimera Sui Generis (Vilgax's species) named Myaxx, who is Azmuth's assistant. She switched her DNA signature for Azmuth's when he refused to give her credit for helping to create the Omnitrix. He also refused to give her the abort sequence for the self-destruct, which as she explains will not only kill Ben, but most of the universe's inhabitants; including Earth itself. Regardless, Myaxx knows how to find Azmuth, and leads them to his home planet.
While attempting to reach Azmuth, they are attacked by Vilgax, who has somehow escaped the Null Void and has commandeered a ship to track down Ben. Ben is ultimately successful in repelling the attack, though the pilot, a slime alien named Gluto, is killed in the conflict. Tetrax's ship crashes on Azmuth's home world. As they enter his mountain fortress, they are attacked by a group of Florauna which apparently eat Gwen, something Ben doesn't take too well. As Ben proceeds with the other two aliens down towards Azmuth's lair, Tetrax empathizes with Ben, revealing his origins of how working for Vilgax cost him his whole planet and everyone he's ever cared for. Tracking down Azmuth to a sealed secondary laboratory, Ben asks him to shut down the Omnitrix, but he refuses. As far as he's concerned, the universe deserves its fate for misusing his creation, which he explains was meant to help understand the various species in the universe, not turn them into weapons. Angry, Ben breaks down the wall with Cannonbolt and attacks him, revealing Azmuth to be an old, curmudgeonly Galvan hiding inside a large mechanical suit.
Vilgax, having recovered from his earlier defeat, leads a massive attack on Azmuth's mountain fortress. Gwen is revealed to have survived, Gluto having regenerated from some leftover material that splashed on her clothes and subsequently helped her to escape, which causes Ben to break down in tears and embrace her in a hug. Ben's actions during the battle renew Azmuth's faith in the universe, so he repairs the Omnitrix and gives Ben a brand-new form to use: Way Big, a skyscraper-sized alien modeled after tokusatsu superheroes. He easily repels Vilgax's army of drones and tosses the villain into space.
With the threat over, Ben offers to return the Omnitrix to Azmuth, since it does belong to him. Azmuth, however, sees Ben as the best place for the Omnitrix to be, both because he is technically fulfilling its original intention and because the Omnitrix attracts trouble simply by virtue of its existence. Tetrax returns Ben and Gwen to Earth, leaving Ben with a new hoverboard to replace the one Ben destroyed during his battle with Animo. Ben suggests taking a trip to the mall to please Gwen, but an announcement about the mall being attacked by zombies disrupts the occasion. Gwen simply states that this is a normal day for them and they all head off.
Race Against Time
This was the live action Ben 10 movie:
In Bellwood, a mysterious figure teleports into town, and immediately starts destroying things. Ben Tennyson , in the form of Heatblast, confronts him. After a short battle, Ben seemingly obliterates the villain. The next day, Ben goes back to school, and has trouble adjusting to normal life again. After a bad day, he and Gwen Tennyson go over some yearbook photos she took. In the background of one with Ben, Gwen enhances a blurred spot and reveals the same villain Ben defeated earlier. Max Tennyson identifies him as Eon , an alien the Plumbers captured almost two centuries ago. When he arrived, he was half dead and brought a device with him called the Hands of Armageddon, which would open a time rift to the alien's home dimension and unleash his race upon Earth if activated. They travel to the containment facility where Eon is supposed to be kept, only to find it empty and his guardian aged to near-death.
Traveling back to Bellwood, Max takes Ben and Gwen to the location of the Hands of Armageddon, guarded by the few remaining Plumbers including Principal White and other people Ben and Gwen known. Eon has them followed and breaks into the facility, but cannot activate the device. When Ben attempts to use the Omnitrix, it malfunctions, glowing and refusing to activate. Eon attempts to kidnap Ben, claiming it to be a rescue, but Ben escapes. Eon manages to corner Ben, explaining that his race learned to control time itself, but trapped themselves by misusing their power. He claims that his fate is intertwined with Ben's. Eon is scared off by an old man who happens to be another Plumber before he can elaborate. Grandpa Max decides it would be best for Ben to leave Bellwood so that Eon won't find him, but Ben bravely refuses and they both come to a deal where Ben will be monitored daily by a Plumber in disguise.
The Plumbers, all around town, guard Ben around the clock. When Ben goes to the school gym to be alone, Principal White attempts to calm Ben's fears just when Eon arrives again and shoves White out of the way. This time, Ben is able to become Diamondhead and fight him off. Later on that day, Ben decides to lure Eon into a trap by purposefully leaving himself open, but this backfires and he is captured along with Gwen and Max.
At the Plumber facility storing the Hands of Armageddon, Eon explains some of the background of the Omnitrix: Ben can only remain in his alien forms for ten minutes at a time, a failsafe to prevent them from overwhelming his personality. Eon knows how to deactivate the failsafe, and in doing so can resurrect himself through the Omnitrix. He does so, and Ben is transformed into a younger version of Eon. The older one retreats since there are now two of him. Reborn, Eon activates the Hands of Armageddon. Gwen and Max manage to free themselves and work to stop him. While Max tries to disable the time rift, potentially at the cost of his own life, Gwen appeals to Ben inside Eon. Ben successfully overcomes Eon, and with the help of the other Plumbers manages to save Max and disable the time rift, sending Eon's race back to their own dimension.
Just when it seems like they've won, time stops for everyone but Ben. The older Eon reappears, angered at Ben's victory. Ben transforms into Wildmutt and fights him off, eventually knocking him into the Hands of Armageddon, destroying them both. After doing an impromptu magic trick for the school talent show, using Wildmutt's timely de-transformation and a well placed stage curtain, Ben finally accepts being just Ben for a while. However, Max points out that aliens are persistent, and as the film ends an alien ship flies towards Earth.
It has been five years since Ben has used the Omnitrix. He has become a normal teenager, dealing with Girls, sports and school. He goes to Grandpa Max to show him a new medal that he got playing soccer. He walks into the new Rust Bucket, finding it wrecked. He looks around to find a DNAlien (Human Alien hybrid) prowling around the Rust Bucket. Ben fights him off (without the Omnitrix) and finds a message from Grandpa Max. With the fear that Max is in danger Ben puts the Omnitrix back on. He and Gwen find Kevin making a deal with the DNAliens and the Forever Knights. Magister steps in and talks to them about the Highbreed, who think they are better than everyone else. In the fight against the Highbreed, Magister is killed and tells them they need to work together to win. Ben, Gwen and Kevin set off to find Grandpa Max finding clues that he has left for them. Ben and Kevin have their problems (mainly when Kevin takes the Rust Bucket.) But Ben and Kevin settle their differences.
The recent message from Max was to locate the Plumbers Kids (via the Plumber Badges.) Kevin has one of these badges which hints that he is a Plumbers kid. Ben encounters an alien named Albedo, who claims he is the true creator of the Omnitrix and he needs Ben's Omnitrix to override his own Omnitrix since he got stuck in a clone Ben form (but they look different). Ben and Albedo clash until Azmuth arrives stating Albedo was an assistant. Albedo is then sent off to the Null Void prison after Azmuth removes his central core.
Ben assembles a team of Cooper, Azmuth, Albright, Darkstar, Julie and Ship and Paradox along with Kevin and Gwen to stop the Highbreed's take over. Ben and his team successfully defeat the Highbreed, and as a result Ben becomes famous all throughout the Galaxy. Vilgax returned upon hearing of this and challenged Ben to a fight. Ben accepted. In order to fight Vilgax, Ben tried to hack the Omnitrix's master control, which caused a feedback pulse and a release of a few aliens which Ben recaptured. The feedback pulse also transformed Kevin into a living being of different elements. Ben eventually defeated Vilgax and his team went on various missions afterwards.
Ben is eventually confronted by a combined team of Vilgax and Albedo who had the Ultimatrix. Ben destroys the Omnitrix and gets the Ultimatrix from Albedo so he can fight Vilgax, Ben goes ultimate for the first time using Swampfire and he defeats his long time arch nemesis.
One year has passed since Alien Force, Ben is now 16 and he is quite famous. He shares a deeper bond with Julie and has become better friends with Kevin. Ben now has a car. Ben battles a news reporter named William Harangue. A new alien enemy named Aggregor appears, he is an Osmosian like Kevin and he wishes to find the Map of Infinity and he absorbs the power of 5 aliens which Ben has tried to save. Aggregor continuously seems to trump Ben and inside the Forge of Creation, Ben is defeated. It is Kevin who absorbs Ben's powers and he defeats Aggregor, but this turns Kevin insane and he leaves. Ben and Gwen continue on a task to find Kevin, Ben and Kevin eventually clash but it is Ben who defeats Kevin and along with Cooper and Morningstar's help, they cure Kevin.
Ben encounters Eon once again and with the help of Ben 10,000 they defeat Eon. Ben is warned by Paradox to beware of Old George (who is St George, one who has had many stories told about him, as well as the founder of the Forever Knights). Ben is now in a fight against the Forever Knights once again. Ben has gone on several other missions. Ben has saved the Spider-Monkey home world from a DNAlien possessed Ultimate Spider-Monkey. He encountered Albedo again who was using his fame to make a theater like show to gain money and try to fix himself out of Ben's form. He fought a few Ultimate Aliens in his watch who developed into sentient beings instead of the blank slates like they should be. He fought Generator Rex and a few more encounters with the Forever Knights. Ben discovered Vilgax is alive and is mistaken for a false god named Diagon and is housed by a group called the Esoterica. Dagon abducted Vilgax who stole Old George's power to try and regain his own power, but Old George got the power back upon touching his sword. Now Ben is set to encounter Diagon if Old George fails. If Old George is to fall in battle then Ben will take Old George's sword which, was an artifact made by Azmuth centuries ago, and must defeat Diagon.
According to Ben, he was at a celebrity gig when a strange storm picked him up and dumped him into Rex's world, where he mistook Rex for an alien attempting to destroy Bellwood. However, he was also mistaken for an EVO, who Rex tried to cure, but both found that they were not what the other thought they were. "Captured", Ben was taken back to Rex's with an unconscious Agent Six following a battle with an unknown enemy he had been chasing through the storm. While in the base, Ben learned of what was going on in that world, becoming confused by some facts, but generally grasping things are not going good. Deciding to team up with Rex, Ben met Caesar, Rex' brother and learned that he had banished the Alpha nanite to the null void, thinking it was an empty dimension. However, Alpha had returned and planned to use the Ultimatrix's energies to upgrade itself into a perfect being; Ben turned into Upgrade and fused with Rex, allowing them to use more powerful versions of Rex's weapons to beat down Alpha. With Caesar's help, Ben entered the Null Void as a stop on the way back home.
In this series Ben has a new Omnitrix an a new alien partner Rook Blonko. Gwen has gone to college and Kevin has joined her so then Ben wanted to go solo. He soon learns of an alien protection racked in Bellwood so he attempts to do something about it. He goes to Mr. Baumann's store and learns that aliens are using what are called "shake down devices" to level establishments that don't pay. It's there that Ben meets his new alien partner and manage to save Baumann's store, but not before destroying some of it. Rook and Ben who is hesitant to take on a new partner soon chase them to a place called Undertown. It's an entire secret city of aliens under Bellwood. The culprit behind this is revealed to be Vilgax's former lackey Psyphon. Along the way though Ben encounters old foes as well as some new ones like the hunter called Khyber, Dr. Psychobos who is a mutant version of the alien species, Ben calls Brainstorm, but it is revealed Ben had a rogue Galvanic Mechamorph called Malware for an enemy.
He was responsible for destroying one of Ben's most prized transformations, Feedback. Many of Ben's older aliens like Stinkfly and Greymatter return. The Halloween Trio get names: Benwolf becomes Blitzwolfer, Benmummy becomes Snare-Oh, and Benvictor becomes Frankenstrike. However Ben also unlocked new aliens like Shocksquatch, Crashhopper, and Gravattack. Also many fan favorite villains from many different series' have returned like Dr. Animo, Albedo, and Vilgax, but also Ghostfreak and Doctor Victor returned.
In the episode "So Long and Thanks for All the Smoothies", the universe is destroyed and so then Ben as Alien X simply builds another universe that was just like the old one. Another major storyline is that Earth was taken over by the Incursean Empire. Ben was defeated and exiled into space where his sentence was death, but he had an unlikely ally. Azmuth also gave him his Incursean transformation which allowed him to return to Earth and save it thus ending the Incursean rule and saving Earth yet again. When Albedo returned he recreated the Ultimatrix and attempted to take over the universe by stealing Azmuth's intelligence, but he was stopped. Gwen and Kevin do make occasional appearances now, but they are simply minor recurring characters now. Max Tennyson is a part of Ben's team again and has been in nearly every episode.
Omnitrix and Ultimatrix:
The Omnitrix (Omni-Matrix) is a wrist-worn device resembling a wrist-watch that was created by an Azmuth of the Galvan to promote universal harmony by allowing creatures transform into other creatures and experience life from their perspective as well as preserve the genetics of every sentient life form in case of extinction. The Omnitrix its original Safeguard Mode was large grey,black and white , it also possessed several different function "modes" which were displayed through color coding in the hourglass symbol on the faceplate. The Omnitrix and the Ultimatrix also serve as a GPS, a communicator, a tracking device, and a database
Active Mode/Green- A trial mode that allows the wearer to transform into an unlocked alien for at least 10 minutes .
Recharge Mode/Red-Recharges the Omnitrix's energy, the watch cant be used in this mode.
Capture Mode/Yellow-Allows the wearer to take genetic samples from different aliens.
Self-Destruct Mode/Orange-Forces the Omnitrix to self-destruct after a certain amount of time
Recalibration Mode/Blue-Updates the the Omnitrix's form and aliens to match the physical maturity of its wearer.
The Ultimatrix is an updated version of the Omnitrix, with a few extra features, such as granting Ben's aliens an "ultimate" form.
Ben's physical appearance has evolved throughout the series from a ten-year-old to a fifteen and sixteen-year-old teenager. However, he retains some recurring characteristics. He has short brown hair, green eyes, pale skin, and he's quite skinny for his age (though his various future selves are portrayed as quite muscular), though he shows a lot of muscle definition due to being athletic. In the original series, his usual clothes consisted of a black-striped, white T-shirt with short sleeves, deep green cargo pants and black and white sneakers. Starting with Alien Force, he starts wearing a black T-shirt, blue skinny jeans and a white-stripped green jacket with the number 10 on it, clothes he retains in Ben 10: Ultimate Alien. Ben wears the Omnitrix and Ultimatrix on his left wrist in a watch-like manner. Like all the other main characters, his physical appearance hasn't changed much.
When the cross over special with Generator Rex occurred, Ben's appearance changed according to the animation of that series, becoming sleeker and more mature.
Ben Tennyson has the ability to turn into any one of 1,000,910 alien creatures from distant planets. This ability is given to him by the device called the Ultimatrix (Originally it was the Omnitrix that allowed him to transform into an alien creature). The Ultimatrix is gauntlet shaped device that acts as a receiver to Primus (An artificial planet containing the codon stream which is a mass of energy containing the genetic signatures of thousands of different creatures). The Ultimatrix also allows Ben Tennyson to evolve to their full genetic potential or "going ultimate" as Ben refers to it. Ben is capable fighter, being trained in martial arts by Gwen.
Original Ten Alien Forms:
Four Arms is a Tetramand that stands at about twelve feet in height, has well developed muscles, two pairs of four-fingered arms, and the Ultimatrix symbol on his chest. His skin is bright red and very tough, as though it is armored. The black stubble stripe goes from the bridge of his nose to his neck.
A second black strip goes from his chin to his lower lip, and he has four eyes: a main pair, and a smaller pair below them.
Four Arms possesses tremendous superhuman strength, nearly limitless endurance and thick skin.
His strength is such that he can create strong short-to-long range shock waves simply by smashing the ground or clapping all four hands together, dubbed the "Big Smack". Four Arms' muscular legs also allow him to leap several city blocks at a time. As shown in Ultimate Alien, Four Arms is strong enough to hold a car on each of his lower hands.
Diamondhead is a Petrosapien, a silicon-based life form that is about 7 feet in height. His body is composed of extremely sharp and durable green crystals. He wears a uniform similar to Ben's clothing which is black on one half and white on the other. He also sports 4 green crystal points on his back and has a sharp head. He has an overall square body design. His eyes are yellow in color, and his Omnitrix/Ultimatrix symbol is on the left of his chest. His name is derived from diamond, a super hard substance originated from coal and "head" the top of his body.
Diamondhead's species have super dense bodies which are composed of extremely dense organic green and purple crystals, making him nearly invulnerable. He is able to manipulate the atomic structure of his crystalline structure and physiology at will, thus allowing him to make crude crystal weapons from any part of his body on demand, and fire crystals rapidly from his hands. He can make huge clusters of crystals, by creating crystal shields, and even make ramps for himself to jump on. In certain ways, he can even reshape his projectiles into certain shapes and can make giant body parts like hands to capture enemies. His crystalkinetic powers don't end there, as he can control the crystals that are not even connected to his body redirecting them. The same ability also allows him to regenerate to a limited extent, such as growing severed or lost limbs. In addition to growing crystals on himself, he can also grow them over other objects. In addition, to his crystalkinetic powers his crystal body itself acts as a living prism, making lasers and weapons similar useless refracting the beams. He also has proved strong enough to easily beat Kevin, defeat Vilgax.
XLR8: XLR8 is a Kineceleran that resembles a semi-armored velociraptor. XLR8 has wheel-shaped feet and wears a helmet with a visor, which is part of his alien biology, leaving the features of his head unknown. Whenever the visor does come up, you can see that he has green eyes and black lips.
Ben 10,000's XLR8 also has a scanner built into the helmet, the product of nanotechnology Ben 10,000 uses to enhance his aliens. The Bandai profile for XLR8 describes the actual species much differently. The profile states that Kinecelerans are vaguely elfin in appearance, with long hair, blue skin, pointed ears and large tails.
XLR8 can manipulate friction to reach speeds of 500 mph (approximately 805 kph) in an instant, and the same power allows him to climb up walls and run on water with relative ease. Using his speed, XLR8 can perform a number of unique feats including creating tornadoes through centrifugal force, either through running in a small circle or spinning, and can deliver speed-enhanced attacks in rapid succession. Amazing reflexes accompany this speed, allowing XLR8 to quickly dodge attacks with relative ease. His scissor-like claws can also cut through objects.
Ghostfreak is a shadowy, ghost-like alien, that has a body that can become intangible at will. This enables him to phase through anything and turn invisible at will. He may have only one eye, but he can position it anywhere on his body by using a track traced along his skin. His appearance can also bring fear in the hearts of others, sometimes, even Ben is creeped out. Ghostfreak can also peel back his own skin, which reveals a horrifying mass of tentacles, which is seen in The Big Tick and Last Laugh. Direct sunlight and chemicals that can affect his body will nullify his invisibility and intangibility. He is a last resort method.
Ghostfreak's fully developed form is truly more menacing than the Omnitrix form. He actually has a skull head, and it's upside down. His tentacles, hidden underneath the first form, are revealed. Spikes grew on his shoulders and through one half of his arms. In this form, Ghostfreak now has claws instead of hands. The skin he had in his Omnitrix form is presumably a safety feature incorporated by the Omnitrix's creator, Azmuth, both to safeguard this alien forms exposure to sunlight and to lessen the frightful impact of its true hideous appearance. This is substantiated by the fact that Ghostfreak willingly ripped it off, despite it being daylight at the time, in order to reveal his true appearance; the true nature of this skin, however, is never fully explained in the series beyond its sun-shielding capabilities.
Ghostfreaks original powers were limited to intangibility and invisibility (accompanied by a inverted color scheme and transparency). It has been explained that he can control his density. He has been shown to be able to change into a smoke like form in Hunted. Ghostfreak can also peel back his own skin, which reveals his horrifying true form, this has been used to terrify Zombozo, fight the giant tick, and as a way for Ghostfreaks inner self to free itself. The original Ghostfreak was grated a second layer of skin to make him usable in sunlight(at the cost of eliminating many of his powers) it is also meant for extreme combat.
Wildmutt is a Vulpimancer that has a body shape that appears to be a cross between a lion, a wolf and a gorilla. His teeth are very defined and are on the outside of his face. Vulpimancers have evolved without eyes, instead using smell and hearing in vision's place, which are aided by three V-shaped gills on both sides of their neck. Ben's point of view while Wildmutt is depicted as being similar to a thermograph sensor, since it detects its surrounding with heat. The Omnitrix symbol is on a brace on his left shoulder. The Ultimatrix is placed on his chest.
Wildmutt possesses a naturally high agility that makes him able to run, jump and climb on objects at high velocity. Most notable, Wildmutt has an incredible heat sensing ability, similar to pit vipers, that allows him to perceive thermal signatures of anything. Wildmutt's sense of smell is also well developed, so much so that he is able to track people from their scent many miles away.
Wildmutt has enhanced strength and possesses razor-sharp claws and strong teeth. While Wildmutt is normally quadrupedal, he has the ability to stand on his rear haunches and brandish his front paws like fists.
Ultimate Wildmutt is significantly larger than Wildmutt. His fur is red and has what looks like a dorsal fin running all the way down his back. He has a tail with a stinger on the end of it. He is now much faster and stronger and can now talk.
Heatblast is a Pyronite, a magma-based life form whose body is composed of brown and red rocks with lava inside. His head is completely fiery, his eyes are connected to that flame which can be put out by a sufficient amount of water. His body is completely hot and does not allow him to be touched. His feet have slight oval like design with only two toes and one back toe. His hands and feet are completely made of magma and his Omnitrix/Ultimatrix symbol is on the center of his chest
Heatblast has the ability to generate, manipulate and project intense heat and flame from his body. He can shape that fire into fireballs, fire breath, flaming discs and fire tornadoes. He can also use that fire in defensive maneuvers such as making a wall out of fire. By propelling himself like a rocket or surfing on a fire board, he's able to fly/levitate. He is immune to fire, heat and magma (unless it's hotter than him) because he can absorb and project it. Heatblast possess great strength and invulnerability.
Heatblast can undergo a process dubbed "meltdown" by Gwen in the episode where Ben turns into an even younger boy. During the fight in the underground cavern with Hex, the young Heatblast raises the temperature inside the cavern to such a degree that the water starts boiling and eventually vaporizes. This feat is also shown in the episode where Ben and family attends a wedding. In the fight with Camille's parents; they combine and devour heatblast by covering him up. However Heatblast used the meltdown skill by raising his body temperature to the point where the mud creatures eventually turned to stone, allowing Heatblast to break out from their stomache.
In any situation requiring flight, Stinkfly is Ben's alien of choice. Stinkfly's thin, rapidly flapping wings allow him to move at high speeds in the air and dodge attacks just as quickly. Stinkfly also possesses disproportionate strength, enough to carry people and objects heavier than himself. Stinkfly's four eye stalks give him a wide range of vision from the sky, including the ability to look directly behind himself.
Stinkfly can excrete high-pressure streams of liquids from the pollen ducts in his eye stalks and mouth. The type of liquid can range in use from flammable toxin, putting out fires to an immobilizing jelly. In Don't Drink the Water, Ben's child form of Stinkfly, Stinkyfly could emit a powerful herbicide gas through flatulation, it is unknown if older Stinkfly can do this. It is shown in Forge of Creation, he shot a light blue beam when Ultimate Swampfire trapped Aggregor with his vines. For melee combat, Stinkfly has a sharp tail and four pincers in its legs.
Upgrade is a Galvanic Mechamorph (mecha- meaning machine and -morph meaning transform) of the planet Galvan B, a formerly uninhabited moon orbiting Galvan Prime. It was said to be born when self-replicating nanotechnology bonded with Galvan B's mineral molecules. It is supposedly the result of some Galvan scientists' dumping of chemicals with self-replicating nanotechnology to that moon, probably by mistake.
He has the ability to reshape himself, as he can turn to some sort of liquid at will. Galvanic Mechamorph's can also stretch their limbs about 20 to 40 feet depending on it's age. Their internal nanotechnology allows for Upgrade's primary ability to merge with and 'possess' any technology within reach by spreading over it like liquid, enhancing it far beyond its original design.
The size of the device is inconsequential. While merged with a device, Upgrade controls it as he would his own body. Even without a machine at hand, Upgrade can reconfigure his form around his eye in order to fire a plasma beam from it. Upgrade is also capable of forming simple constructs from plasma, such as spikes, and also partially posses a machine to enhance his lasers. He can phase through metal and technology.
Ripjaws shares a number of traits of Earth aquatic life-forms-namely alligators, eels, anglerfish, and sharks-combined into a single being. He has a fish tail when underwater and is bipedal when on land, and a phosphorescent light on his head. He is able to breathe underwater, as well as swim at high speeds with amazing agility, and can also withstand amazing pressure. His luminescent angler allows him to see in dark areas. Ripjaws uses his claw-tipped fins and razor-sharp teeth to attack enemies with strength superior to a person. His powerful jaws can bite through metal. Ripjaws can unhinge his lower jaw to swallow large objects in a single bite. He can transform his legs into a fish-like tail when he's underwater, by bringing both of his legs underneath the black loincloth coming down, and vice versa when on land.
Grey Matter is a gray-skinned, frog-like, bipedal alien only six inches tall with large green eyes. The Omnitrix symbol is located on his back.
Grey Matter's size belies his great calculative and technical intellect, and when it comes to intellect he's second to none of Ben's other aliens (it's unknown, however, if Brainstorm can match him). He can create almost anything from spare parts and deduce the function of any device at a glance. Also, Grey Matter's intellect serves as a problem solver and analytical help in difficult situations. Additionally, he can sometimes control living things by stimulating certain parts of their anatomy, apparently applying the same basic principal as a horse and its reins. His diminutive size allows him to squeeze into small spaces, and he can climb walls thanks to tiny suction cups on his skin. He also has sharp teeth and his slimy skin makes him difficult to grab
Cannonbolt is a hulking, broad-shouldered alien covered in natural armor plating on its back, shoulders, and the backs of its arms. This armor can withstand acids, lasers, and even a g-force drop from space without any harm to the inside of the ball. Cannonbolt can roll into a ball like an armadillo or pill bug to encase itself in this plating. There is enough space within the shell while rolled up to protect and transport people or objects. When in the form of a rolled-up ball, Cannonbolt can increase its rotational momentum and roll into enemies as an attack, as well as ricocheting himself off surfaces.
Cannonbolt demonstrated his extremely tough plates in Ben 10: Secret of The Omnitrix when he broke through three electric, metal doors in order to get to Azmuth, the creator of the Omnitrix. However, it is subjected to the physical laws of reflection and conservation of momentum, meaning that it has difficulty stopping or controlling its direction if it picks up speed. By spinning in the same spot rapidly it can create a tornado like XLR8 and Terraspin .
Cannonbolt's armored shell is a defensive mechanism that is extremely resilient (but because of Ben's creativeness he has adapted this to attacks).
The shell is durable enough to survive a free fall from the upper limits of the Earth's atmosphere and including the heat of atmospheric re-entry, and still leave Cannonbolt and anything held inside the ball intact, though the landing still creates some pain due to the large crater left there. Nothing has been seen that can penetrate the shell.
Ultimate Cannonbolt has metal plating all over his body and much harder blue-ish skin. He is much larger than Cannonbolt.
Wildvine has five tentacle-like legs, four claws on his hands, and venus flytrap-shaped flaps covering its head. It has pods on it's back that are either explosives or smoke bombs. He also has one eye in the middle of his face.
Wildvine can grow seeds on its back that contain a whole host of substances (both non-lethal and lethal), partly control surrounding plant life, extend all parts of his body,can grow and retract most of his body and can merge with plant life, like a tree, then control its branches and other parts. He is also capable of digging underground as shown when fighting the Yenaldooshi in Benwolf (episode). Since Wildvine is a plant based alien, he can also grow defenses on his body like thorns extremely quickly. Wildvine is much more adept at its plant like abilities unlike Swampfire.
Upchuck has four strong, adhesive tongues that can stretch to great lengths, allowing Upchuck to latch onto large objects and reel them in with relative ease. Upchuck's mouth and stomach can also stretch, allowing him to swallow and digest objects fairly larger than himself. Upchuck possesses several acid-filled stomachs that dissolve almost all forms of matter, except, ironically, ordinary human food and other organic matter he hates. The items ingested are converted into explosive balls of liquids that can be expelled at will with great accuracy. He can also make them curve, like a boomerang, shuriken, or frisbee.
He can also use the energy as an acid. Upchuck seems to be able to take a surprising amount of punishment for a creature of its size, taking the force of a moving car impact as well as surviving after being thrown through a wall. In the Ultimate Alien episode Duped, it is shown th he can spit out slime like Spitter.
Way Big is a To'kustar and he is the biggest alien in Ben's arsenal. Way Big's extraordinary size of over 120 feet (approximately 67 meters) grants him immeasurable strength and invulnerability to even the strongest and most powerful of attacks.
Due to his enormous size, Way Big can easily overpower most of his opponents because he packs enough power to beat an entire army. His size also grants him incredible strength and he has also shown great durability, withstanding fire from enemies while barely even feeling them.
For his size Way Big is incredibly fast but takes a bit of a build up. He was able to run around a trash monster bigger than he was and generated a cyclone like effect that sucked up the monster and sent it hurdling into space. Way Big can also fire powerful cosmic rays
In addition, he is immensely strong and powerful even for his size. He can create shockwaves equivalent to earthquakes, beat Vilgax twice, and even outmatch Evil Way Big (a "member" of his species, hence the name) and send him flying all the way from Tokyo to outer space/the moon (in Cosmic Destruction), but it should be noted he use the poltis altiare to fight Evil Way Big/Albedo.
Ditto is a small, humanoid alien with the ability to clone himself without limit. Every clone operates independently, regardless of whether or not the others wants them to, and each clone is indistinguishable from the others. The child-size Ditto is also no stronger or faster than his size suggests.
All of the clones share a link with each other, making it so that when a clone is hurt, the other clones feel its pain. Also, if one clone is killed, the others are automatically killed as well, thus negating the ability to form many clones. If one of the clones is separated from the others by a great distance, then when the Omnitrix times out, the wearer will not transform back into normal, or be able to become another alien until all the clones are brought back into one. Ditto, while cloning, is vulnerable because when he clones opponents can attack them.
Eye Guy's upper-body is covered with eyes, hence his name, although he ironically has no eyes in his head, which consists of a mouth and a very large pair of bat like ears for his head.
From his eyes, Eye Guy can fire numerous green energy beams. The eyes can be merged to create different effects, such as three on his shoulder which can form a freezing beam. By merging every eye into the large eye in his chest, he can fire his strongest energy blast. When he does, his eye almost detaches from his body. It is unknown how this will work in Ultimate Alien because he does not seem to have his chest eye. He also can climb walls.
Blitzwolfer is the first form that was taken from another alien via capture mode. Blitzwolfer first appeared in the episode Benwolf, when Max goes to see an old friend who lives in New Mexico. In the episode, after some continued fight, Ben's Omnitrix is scratched(with no damage on it) by the Lobon thought to be the Yenadooshi. The Omnitrix was somehow stuck between Capture Mode and Active Mode, and as a result, the transformation is gradual instead of instantaneous (like a werewolf).
Blitzwolfer is very muscular, tall, has dog-like back legs, stands on his back legs, and has a face and muzzle that looks like a Mexican wolf's face and muzzle. He also has many animal-like tendencies. Blitzwolfer has enhanced strength, speed and agility; supposedly being able to lift approximately 500 lbs and run over 70 mph. In addition to Blitzwolfer's formidable claws, fangs, and muscles, he can emit an ultrasonic howl if the parts of his quadra-hinged muzzle is opened and a shout is let out. He can also do a jump attack by using his claws to slash the air.
Snare-oh's appearance differs slightly from the other Thep Khufans. His eyes and the gaps between its bandages glow green instead of purple. Snare-oh also has black bracers and greaves, as well as a smaller mask and the Omnitrix symbol on his left shoulder. Snare-oh can speak, even though the other Khufan that attacked Ben seems to be mute. In originial series, Ben didn't know how to use Snare-oh's powers when he turned into this alien.
Similar to those used on Egyptian mummies, Snare-oh is also covered in many bandages. This allows Thep Khufans to reshape their bodies at will, splitting themselves apart to dodge attacks and reforming to counter- attack. To compensate for its relatively weak form, these aliens can recover from basically any injury, including being torn into confetti by a large fan, almost instantly and with no visible repercussions. When Ben first uses the form, he had trouble figuring out how to control it; Ben quickly discovers how to stretch his bandages, but has not displayed knowledge of the advanced reshaping techniques yet. Snare-oh can also use his bandages as some sort of tentacles which allows him to grab his enemies and throw them with ease with out the use of his super strength. Snare-oh's bandages make him extremely light, allowing him to be thrown by beings with human strength or blown away by strong enough winds. Despite his build, however, Snare-oh is still incredibly strong. In addition to strength, Snare-oh also has a surprising amount of speed and agility, enough to scale walls and dodge attacks with relative ease. His composition also allows him to survive in a vacuum. This is probably due to the fact that his body is made of fibers that come from the shell-like head. The head is the only "true" part of the creature.
Frankenstrike can generate "green" (unlike like the normal purple of the species) electricity and manipulate the resulting energy to attack enemies or adhere himself to metal through magnetism. He also possesses enhanced strength and intelligence. Frankenstrike has two conductor coils on his back which can generate the electricity and a power pack on his back with which he can control technology by connecting the wires on his back into a device. He also can withstand attacks fairly easily, and is very tough. Due to his robotic nature, he can survive in a vacuum.
Spitter is a Spheroid alien from the rainy planet of Scalpasc. He is a large, green, blowfish-like alien. His ability is to spit slime at high pressures. It was first used by Ben in Ben 10,000.
Spitter has showed only one ability so far. He inflates (possibly from the creation of the green-yellow slime) and then spits out a concentrated blast of slime. The slime is very slippery and can be acidic and has been shown to be highly conductive. It is also assumed he uses his sharp teeth as an offensive weapon.
Spitter resembles a pufferfish, and sort of looks like a pufferfish when puffed up. His legs are black, and his yellow bulbs resemble eyes. He also has little spikes on his head.
Articguana is a blue iguana-like alien, of the species Polar Manzardill from the polar planet X'Nelli. He can breathe freezing vapor and was used by Ben in Ben 10,000 to freeze Vilgax. He was first called "Absolute Zero" by the adult Ben, but was changed by child Ben to Articguana.
His appearance somewhat resembles a cross of a fish and an iguana. He has the powerful ability to work with cool temperatures, and he can freeze his enemies before they can even lay a hand on him. He seemingly wears white pants and a black open-front shirt with white cuffs. He has three dorsal fins reaching down his back, and gills on the sides of his head. He also has small spikes around his face. Much of Articguana is still unknown.
He can create an icy blast from his mouth capable of freezing objects instantly, as shown when he freezes a large amount of water in only a few seconds. It seems that he can even control ice and cold air. This is called cyrokenisis.He can live in very cold temperatures. Seeing that he has gills, it is possible he can breathe underwater and is an adequate swimmer.
Buzzshock can pass through any electrical source with amazing speed, and has the ability to manipulate electricity. Buzzshock can duplicate himself when he is cut in half or has enough power. He can also fly. Although not too much has been revealed, this little alien can really shock, and its species has a dangerous(and very immature) sense of humor. All powers were seen in the original series in the episode Tourist Trap. Unlike regular Megawhatts, Buzzshock's electricity is the color green, because of the Omnitrix.
Swampfire is a humanoid plant like alien that has an overall green and black colored body mostly with a flame-pattered head and root-like feet seemingly connected to rocks. Also, the top portion of his body has red petals same as the color of his head. His species is taller than that of an average human, and has a distinct rotten smell that only worsens with heat and/or fire.
Swampfire has the power to control fire and plants. He can reattach severed body parts and/or regenerate them with ease. His fire abilities include throwing fireballs, shooting flamethrowers, releasing heated air, immunity to fire, and burn enemies with a ring a fire as shown in Vilgax Attacks. His plant controlling powers include controlling outside plants, spraying methane gas, vine generation, burrowing underground and from one place to another as tall plant-like structures, and seed bombs that once thrown, grow into a flurry of vines and plants who are under his control. He is also shown to have superhuman strength and semi-invulnerability. Furthermore, shown by Albedo in The Final Battle Part 1, he can spray sleeping powder that knocks his foes out cold.
Ultimate Swampfire is the evolved form of Swampfire. Ultimate Swampfire's pyrokinetic and chlorokinetic abilities have dramatically increased. Though he can no longer regenerate his resistance to damage has increased. His blue colored flames are three times hotter then Swampfire's. He can shoot huge blue fire balls with powerful destructive power, create fire tornadoes and suck in enemies.
Goop is a shape shifting, self regenerating, almost indestructible green blob. Goop can wrap his slimy body around his foes and throw them around. Ben usually becomes Goop to avoid damage or needs a flexible form. Goop controls his slime with an Anti-Gravity Projector in a shape of a small UFO, and if the slime and the Anti-Gravity Projector are separated at least two feet the slime will become inert until the Anti-Gravity Projector recollects it, though in recent appearances, it seems that he can move without it unless the button on it is turned off. The Anti-Gravity Projector can cause the slime to take any shape and even hover off the ground and nothing can cut through Goop and he can imprison someone inside of the slime, his Projector can also hover alone and cut enemies.
Big Chill is a humanoid moth like alien whose wings and antenna can fold into a hooded robe big chill. Big Chill is capable of breathing a freezing vapor that automatically lowers the temperature and encases it in a layer of ice. Big Chill can also generate a freezing beam from his hands that he can manipulate at will. Big Chill's body contains a density altering protoplasm that allows him the ability to turn invisibility and intangibility. Big Chill also possesses enough strength to lift a car.
Ultimate Big Chill is the evolved form of Big Chill it can do everything big chill can do but he can breath much colder close to absolute zero and freeze much faster he also can create ice flames which is a heat draining plasma beam it consumes heat from any thing it touches.He can also survive in the deeps of the ocean and in space.
Chromastone is a silicon based life form made of nearly indestructible super dense silicon and also has the ability to absorb energy like a conducterand channel it into ultraviolet laser beams or intense natural light which can destroy whole turrets he is also able to alow energy to pass through him his body via light refraction which is blasted back at his foe he can produce blast with out absorpsion it may be due to sun light street light or just ambient energy he can also create energy shields to defend him self he posesses super strength he also has the ability to generate he is also very durable and has flight.
Humungousaur is a Vaxasaurian with the ability to grow taller at will up to 60 feet possesses super strength his strength increases with his size and a thick layer of skin the protects against injury Humungousaur has proven durable enough to survive in space for a few minutes also took a car speeding car hitting at him with out being hurt he is very strong he was able to lift a building and throw it on Aggregor he also can roar loud enough to push or scare away enemies.
Ultimate Humungousaur is the evolved form of Humungousaur but his strength is well above the normal Humungousaur. His skin is nearly impenetrable and also has the ability to shoot bones from his hands and has a mace tail.
Spidermonkey is a Arachnichimp Spidermonkey is alien with four arms and four eyes. Spidermonkey can spin webs from his tail that are as strong as steel. Spidermonkey has strong adhesive skills, superhuman agility, above average strength, and enhanced hearing.
Ultimate Spidermonkey is the evolved form of spidermonkey but like all of the Ultimates has an increase in power. It spits webs out of its mouth by splitting its jaw instead of shooting out of tail. His webs are stronger then Spidermonkey's and he can shoot much much more webs and also is physically stronger.
Alien X one of Ben's most powerful aliens and is a Celestielsapien from the Forge of Time. Alien X is omnipotent and able to warp reality and space/time itself becoming nearly invincible. The only problem is any action including not limited to simple movement and transforming back to ben at least two or three must agree on it this reveals to be a major weakness and they almost never agree on anything.
Echo Echo is a Sonorsian. Echo Echo can scream at a ultra sonic frequencies capable of shattering metal. Echo Echo can also make duplicates of himself. The duplicates are not linked as he can make an almost unlimited amount. He also seems to have enhanced strength as he was able to kick off the trunk door from Ben's car.
Ultimate Echo Echo is the evolved form of Echo Echo. Like Echo Echo he control and manipulate sound. He is a lot stronger then Echo Echo as he can create sonic booms that can shatter metal, steel and iron easily. He can also fly by projecting waves around himself allowing him to fly fast enough to cause a sonic boom and open a portal to hyperspace. He can create sounds waves strong enough to contain a mini nuke. He can also make sound disk that have major destructive power hit Kevin though several buildings.
Jetray is a Aerophibian. Jetray has the ability to fire neuroshock blasts from his eyes and tail with destructive force and can also fly and swim at supersonic speed. Jetray is also a good hand to hand combat fighter and is very durable. He took gun fire from a jet fighter without injury and can survive in space with no need for air. Jetray can also can enter hyper space and move at speeds faster then light. He also possesses a certain amount of strength as he managed to push Ultimate Kevin back.
Brainstorm is a Cerebrocrustacean that possesses the ability to control electricity energy and make force fields around objects. Brainstorm can also telekinetically move objects from humans to a train using his electrical energy. He is also intellectually gifted, being one of Ben's smartest aliens.
Rath is an Appoplexian. It resembles a giant bipedal tiger and it's main power is superstrength, allowing Rath to toss cars around easily, leap large distances easily, and possesses enhanced agility. Rath is extremely durable, capable of taking laser blasts with no effects and even falling hundreds of feet with little to no damage. Rath also possesses a retractable spike on the top of each hand. These spikes are strong enough to cut into Plumber ships with ease and when stabbed into the ground can create shock-waves. Rath also likes to refer to himself into the third person and whenever he talks to someone he usually starts with "Let me tell you something" followed by the person's full name. Rath is a very powerful alien in Ben's arsenal but the main weakness is Rath is not very bright and is very aggressive.
Armodrillo is a Talpaedan that is a large robotic armadillo like alien. Armodrillo is capable of digging at incredible speeds, and can create earthquakes by pumping the jackhammer like pistons on the back of it's arms rapidly. Armodrillo alien is quite durable and possesses incredible strength.
Terraspin is a Geochelone Areio. It's power is to create powerful whirlwinds by retracting in his shell and blowing air through the holes on its chest. Terraspin and his race are also impervious to magic.
NRG is a Prypiatosin-B. It is a radioactive energy being that is clad in a special suit to keep its radioactive energy in check. In this form Ben can fire blasts of radioactive energy beams which burn and corrode metals. The suit grants enhanced durability, it is very difficult to puncture, drill through, and dent. The suit allows Ben to go into hazard zones as well.
Water Hazard is an Orishan. It has a hard exosuit which protects it from many forms of damage including radiation. It's main power is to shoot high pressurized blasts of water.
AmpFibian is an Amperi. It is a jellyfish like alien that possesses the ability to shoot lightning. He can also breathe underwater, swim at high speeds, fit through tight spaces, travel by turning into electricity and absorb electricity.
Shocksquatch is Ben's fourth electricity based alien. He is a thick muscular Yeti-like alien. The fur on the top half of his body (excluding his arms) is white, and the fur on the bottom is blue. He has pointed eyebrows and a pink face. He has two grey metal circular bolts on his jaws and on his hands. He is able to build up very large amounts of electricity, enough to temporarily immobilize a fairly powerful cosmic entity, as was shown in Ben 10/Generator Rex Heroes United.
Atomix has a humanoid robotic appearance. He has a white body with large green cylinders on his wrists that store atomic energy. Atomix acts with a righteous personality, and speaks to others with proper titles. Atomix has the ability to create atomic blasts, he is also able to fly.
Feedback is an Conuctoid. He has the ability to redirect, absorb and create electricity. Feedback has two antennae and a tail that feature plugs on the end of them, that allow him to draw energy to himself. He has four fingers each with a plug on the end of them. Feedback first appeared in Ben 10 Omniverse: The More Things Change, Part 1.
Bullfrag is an Incursean. He is a humanoid frog-like alien with 3-fingered hands and 2-toed feet. The only known abilities known is super agility and strength. Bullfrag first appeared in Ben 10 Omniverse: The Frogs of War, Part 2.
Toepick is an ogre like alien with a dark-green metal cage on his head. The metal cage on his head has two protruding horns on the sides. Toepick's abilities are fear hormones released when he opens the cage door on his head, the hormones can have extra effects at times including sickness and madness. Toepick first appeared in Ben 10 Omniverse: Special Delivery.
Astrodactyl resembles a cross between a pterodactyl and a gilder. He has a beak like mouth and small wings connected to a "jetpack" on his back. Astrodactyl has the ability to fly and has the ability to survive in the vacuum of space, he is also seen to fire energy beams from his mouth and use energy whips.
Fasttrack is a Citrakayah. A feline-like alien with a black and blue suit like color scheme. Fasttrack has super agility and speed, he also has super strength. Fasttrack first appeared in Ben 10 Omniverse: Basic Training.
Pesky Dust is a Nemuina. A short fairy like alien with blue skin and purple wings. Pesky Dust has the ability to fly, he also has the ability to create "sleeping dust" to put them asleep and to then enter their dreams to manipulate them. Pesky Dust first appeared in Ben 10 Omniverse: Outbreak.
