Spartan was born Yon (or Yohn) Kohl, a flesh and blood Kherubim and member of the Pantheon Class on Khera. Growing up like most of the Pantheon, Yon was trained to be a warrior from birth. The creatures he learned to fight against were the Daemonites, his races sworn enemy. He became a war lord that was so respected that his body was used as the template for the Spartan Guards (see Kherubim Technology). Some thousands of years ago, Yon was aboard a Kherubim vessel that found itself locked in battle with a Daemonite ship in the space above Earth. The ships battled fiercely and both were damaged and crashed to the planet. Over the next thousands of years, the Kherubim-Daemonite war continued, but both sides began to blend in with the humans that surrounded them (Kherubim looked human and Daemonites could shape shift and steal bodies) and their battles became less and less visible.
In the 1930's Yon Kohl changed his name to John Colt and began a career as an adventurer and and American Hero. His abilities weren't as great as some other Kherubim on Earth (like Mr. Majestic) so many believed he was just a normal man, his abilities no more than anyone could acquire if they trained, persevered, believed in themselves, and believed in the nation. He was major John Colt, a normal American serving his country. He was a super patriot, the Captain America of the Wildstorm Universe. Because of this, he was chosen to be a member of a special team built to stop an alien menace.
Spartan was created by Brandon Choi and Jim Lee.
In the early 60’s a Daemonite named Helspont made a move against humanity. He tried to start a nuclear war between the most powerful nations on Earth in order to get humans to destroy themselves so the planet would be empty for the Daemonites. Lord Emp, a Kherubim, created Team 1 to combat Helspont and the villains he had gathered to help him. Team 1 was made up of many characters that would go on to their own roles in the Wildstorm Universe and John Colt was asked to be a part of this team. He accepted, becoming the field leader of the group. As soon as the team was formed, they were sent into battle against Helspont, who had already seized control of a US missile base so he could get access to a nuke.
As Helspont got ready to launch the missile, Team 1 arrived and a fight ensued. Team 1 was vastly outnumbered and things quickly got out of hand. John was taking on a legion of Daemonites on his own, but they were getting past him and were making their way to the member of his team that was responsible for stopping Helspont's bomb from launching.
John was in the middle of the aliens but couldn't take them all out so he ordered Majestic to use his laser vision to kill them all. Majestic didn't want to do it since it would kill John too, but there was no other choice so he blasted them all away. Even though John sacrificed himself, the team still failed and the missile was launched. Fortunately, one member of the team (Regiment) jumped on the missile and destroyed it as it flew, possibly dying in the process.

WildC.A.T.s - Spartan/Hadrian
Though John's body had died his mind lived on. Before he had been killed, Emp copied John's personality so he could attach it to a prototype Spartan android later. Emp perfected the android and in the 90's when he started the WildC.A.T.s, Spartan was born and was made the leader of the team (His codename was Spartan after the android guards on Khera but he also went by Hadrian).
He had no memory of Team 1 or his life before and though he had his/Yon Kohl/John Colt's personality, he was emotionless and acted very much like the robot he was. It wasn't until the team was together (and the addition of Voodoo) that Spartan started to come alive. He and Voodoo started a relationship and he started using the name Hadrian more when he wasn't on the battlefield.
After the team went on a mission to stop the Daeomites from reactivating their ship the Kherubim ship was found as well. However their ship was set to detonate and the team flew the ship into the atmosphere so it would harmlessly explode and the team was thought to have died and only Spartan survived but his body had sustained major damage. He was repaired by Stormwatch and even became a member for a time until his death during a mission. Else where it was revealed the WildC.A.T.s had lived and use the ships hyperdrive to travel to Khera.
While there they found that the battle with the Deaomites was over thousands of years ago and Khera was the victor. Using a backup disk of Spartan Emp rebuilt him in a more powerful body using Kherubim science and acted as Emp's guard. He would come across a plot to kill Zealot and before he could reveal this he was almost destroyed. Luckily the team found him repaired him and stop the plot. After finding out much of the terrible things the Kherubim had done they left the planet.
After going home the team traveled to Gamorra island to battle the ruler Kaizen Gamorra. It was discovered he was really John Colt whose body had been healed and sent to replace the captured Gamorra. After a battle with Spartan that ended with Kaizen being dethroned he was killed by Mr. Majestic again. John Colt was now awakened in Spartan who even began to use the name John Colt.
Later after the team disbanded after Zealot's apparent death, Emp and Spartan went to battle the villain Kenyan. Emp hoped he could get Kenyan to kill him so he would be able to ascend and the release of energy would take Kenyan with him, but he instead took his own life, however Spartan killed Emp and thanks to some upgrades survived the explosion.
Spartan realized that the superhero lifestyle wasn't the most efficient way to meet Emp's wishes for a better world, so Spartan took the identity of Jack Marlowe and decided to wield the Halo Corporation as his tool to improve the world. It is during this period that a superhuman serial killer called Samuel Smith surfaces and had been making his way across the United States. Samuel targets Voodoo, injuring her throat and slicing off both her legs with his eyebeams. Smith also temporarily blinded Maul when the latter tried to defend Priscilla. Furious, Jack set a trap for the killer, who was finally killed by Grifter, although his death didn't give Marlowe any kind of pleasure or satisfaction.
Marlowe began to use Kherubim technology in order to produce high-tech equipment, far beyond any created with human technology. During this time Void, Noir, and Grifter joined the Halo Corporation. Void became a great asset to the corporation because her ability to teleport allowed her access to Otherspace, a realm of limitless energy. Noir discovered that the matter in Otherspace could be used to create batteries that would last forever. Betraying the corporation, he attempted to kill Void and reprogrammed Ladytron, another former Wildcat.
Marlowe saved Void by merging with her; this greatly increased his own powers as well as allowing him her ability to teleport. He easily defeated the newly reprogrammed Ladytron and transported Noir to Otherspace, where he would meet his death without a protective suit. Marlowe then utilized Noir's plans and began producing batteries that would last for an eternity.
This was only but the first step in a plan to better the world and he soon bought other companies, including an accounting firm. Edwin Dolby, an intellectual employed at the accounting firm, was fascinated by Marlowe's plans for the future and in time became his right-hand man. Meanwhile, Grifter performed black ops missions under Marlowe, including the liberation child laborers.
The discovery that Halo Corporation batteries could fuel a car indefinitely resulted in the production of Halo Cars. These Halo Cars that didn't depend on gasoline shocked the entire world and many politicians and businessmen marked Marlowe as a threat. An assassin was sent to Halo, but was easily handled by Marlowe, who wasn't impressed in the least by these threats. After Grifter learned the whereabouts of Zealot, who had been captured and imprisoned by her former followers, he orchestrated a mission to liberate her.
Although Marlowe said he could not help his effort due to his fear of harming the integrity of the Halo Corporation, he did use his abilities in order to manipulate the battle from behind the scenes so Grifter could be successful. Jack Marlowe also sponsors the Seminary. The Seminary is a school for young superheroes.
Because of actions taken by Nemesis orchestrated (unbeknownst to her) by the Wildcats old friend Tao, the world all but ended. The moon was destroyed, the Earth's orbit shifted, most of the planet's technology was obliterated, many heroes were missing, more SPBs than ever had appeared, and the Wildcats were only slightly better off than the rest of the world. The team was hit hard and the only reason they had a foothold in the world was because of the Halo batteries from 3.0. When most of the technology went out the energy in the batteries that could run forever kept the Halo building functioning.
It was damaged, but it still worked so the Wildcats kept it as a base and shelter for whatever people they could find in the outside world. They couldn't get any more power though because the energy only worked around the Halo building and they couldn't just go get more since Jack Marlowe's Void powers were the only way to get to the dimension where it came from and Jack wasn't Jack anymore. He'd lost his Void powers when a new Void was born (Captain Atom: Armageddon) and his more advanced robotic abilities had been lost during World's End as a result of a particularly destructive EMP in his vicinity.
He changed his name back to Hadrian (or Spartan) and was in an even worse state than he was at the beginning of Wildcats. He was back in his old body but the drastic shift from being practically a god to a robot really messed with his head and he no longer considers himself the leader of the team.
Powers and Abilities
The Spartans are fully sentient robots that are built as personal bodyguards as well as a police force on Khera. Each Spartan has a "brain" more powerful than any other computer (on Earth or otherwise), is programmed to be able to use any technology it comes across, is equipped with powerful lasers, is skilled in armed and unarmed combat, has superhuman levels of strength, speed and durability, superhuman senses, and posses the ability to fly.
Spartans are also capable of self-repair so they can mend themselves after battle. If the damage is too severe they can transmit their intelligence to other machines to stay alive. Spartan's connection with other machines is rather impressive. He can wirelessly connect with any computer system and bend it to his will. In an alternate future he showed himself to be adept at controlling hundreds of copies of himself in battle at once. Over the years Spartan has been upgraded many times and is even more powerful than he was originally. The greatest change was his acquisition of Void's powers.
Spartan is now capable of teleporting himself, others and objects from place to place with no effort. Distance is not an issue (he has easily gone from his office to space and back) and neither is precision. He can teleport specific things, large groups and even move different things all across the world at the same time. His teleportation also allows him to enter other dimensions at will. Aside from teleportation, Void's powers increased all of Spartan's physical attributes, making him now strong, fast and durable enough to face beings like Mr.
Majestic in all out combat and win. His use of energy has also been affected and increased. Not only are his energy blasts now more powerful, Spartan is able to create energy shields, holograms, and energy constructs formed from pink light, the signature color of Void's powers.
Spartan appeared in Deathmate crossover.
