Sentry has recently been revived (or has reappeared) by the Apocalypse twins through the use of a death seed, which they obtained by killing a Celestial with Thor's old weapon. The purpose of this was to create a new team of Horsemen, known as the Horsemen of Death, the team consists of Banshee, Grim Reaper, Daken and Sentry.
In the year 2000 Bob Reynolds, a seemingly normal man, suddenly recalls that he is the superhero known as the Sentry, the man with the power of one million exploding suns. Along with this recollection, he also realizes his arch-nemesis, the Void, is returning to the world. Reynolds immediately begins seeking out the rest of the world's most prominent superheroes to warn them of the coming threat.
Various heroes' memories of Sentry are restored as Reynolds talks to them individually. Peter Parker had taken a photo of Sentry that had earned him a Pulitzer prize. Sentry had also flown countless times with Angel to help him overcome his fear of falling. And Hulk has never forgotten Sentry, whom he only ever referred to as Golden Man. Sentry had helped Hulk keep control of his rage; later, this was revealed to be a product of a calming aura the Sentry can give off, which helped the Hulk work to be a force solely for good and to gain public approval. The people eventually remember their own memories about the Sentry and his former sidekick, Scout. Most importantly, Mr. Fantastic remembers that he and Robert Reynolds had been best friends and that Sentry had often teamed up with the Fantastic Four to fight the world's greatest threats. Over time the general public slowly remember the Sentry and the good he had done for the world.
During the course of an investigation into why the world had forgotten Sentry, Richards and Reynolds make a discovery: the Void and the Sentry are two parts of the same torn psyche. The reason the world forgot the Sentry was that Reynolds had used his power to erase the Sentry from the memory of everyone in the world, including his own, thus destroying the Void once and for all. With the heroes of the world united and waiting for the Void to come, Reynolds comes to the realization that he must make the sacrifice again. With the help of C.L.O.C., Mr. Fantastic, and Doctor Strange, he once again erases the memory of Sentry from the world.
Marvel promoted a limited series of The Sentry as an appearance of a forgotten Stan Lee hero of the Marvel Silver Age. This story was, of course, fabricated and further pushed by the comic magazine Wizard: Guide To Comics. The hoax involved a false discovery of lost sketches by artist Artie Rosen of a Stan Lee created superhero predating the Fantastic Four.
Major Story Arcs
The New Avengers
In the first issue of New Avengers, Robert Reynolds is a prisoner of the Raft, a prison built specifically to house super-villains. He had voluntarily imprisoned himself for the murder of his wife, Lindy Reynolds. During a jailbreak at the Raft, Sentry turns and defends several of the Avengers from Carnage, who had already beaten several members to a standstill. Sentry easily overpowers Carnage, flies him into the depths of space, and tears him in two.
Taking a great interest in the now free Sentry, the Avengers begin investigating his dark persona. They soon realize that the Void is actually the result of a cerebral virus created by Mastermind. This virus damaged the Sentry's ability to remember any facts of his life. In a cry for help and an amazing show of power, Sentry transferred his memories into comic book writer Paul Jenkins, who transferred those memories into a popular comic book series. Emma Frost releases Sentry from the bonds of his virus, and he recalls much about his life, including that he never actually killed his wife and that his Watchtower stood atop Stark Tower, where he had subconsciously hidden it from public view.
With his memory recovered, he joins with the Avengers and begins fighting alongside them.
Destruction of The Void
Returned to the world, the Sentry captures the hearts of the public. Newspapers begin referring to him as "the Golden Guardian," as he saves hundreds of lives on a daily basis; Reynolds' psychological problems, however, had worsened. Unable to reconcile that Robert Reynolds, the Sentry, and the Void were the same being, the Sentry contained the Void in a vault in the Watchtower. At C.L.O.C.'s urging, Reynolds' psychiatrist Dr. Cornelius Worth enters the vault and finds only a chair and a mirror. When Cornelius confronts Reynolds with this, Reynolds becomes confused and runs to the fairgrounds where he first gained his powers.
Cornelius follows Reynolds to the fairgrounds where the Sentry and the Void had been fighting. The Void claimed that Reynolds transformed into the Void rather than the Sentry, and that the Sentry was merely a guilt-borne byproduct of that transformation. With only half of Robert Reynolds' memories (the Void possessing the other half), the Sentry isn't not sure the Void was wrong. The Sentry chases the Void away and then explains to Cornelius why Reynolds had hired him in the first place. Reynolds subconsciously wanted someone to reveal the Void's existence to the world so he would no longer have to hide that aspect of himself. The Sentry told Cornelius that he knew all along that the Void was never in the Watchtower's vault. He knew that if Reynolds believed the Void to be in the Watchtower, the Void would really be there. This kept the world safe from the Void for as long as the Sentry could keep up the charade.
The Sentry then reveals the true way he gained his powers. He ingested a super soldier serum developed in order to get high as a teenager. The Sentry then visited Dr. Strange to determine if he was real or not. Strange tricked the Sentry into traveling to his old Professor's research facility, and on an attempt to prevent any further destruction, the two men confined the Sentry in an illusionary realm in which he was a mental patient and superheroes didn't exist. The Sentry breaks free of the illusion and, after confronting the Professor, travels to Antarctica to confront the Void in order to discover what memories of Reynolds the Void has in his mind.
In the Antarctic battle, the Void reveals that the serum Sentry ingested was actually super-saturated, an exponentially more potent super-soldier serum than what created Captain America. This was considered dangerous by SHIELD because Sentry's blood could be used to create enough serum to power the entire world population; several attempts had been made against both the Void and Sentry to kill him. Enraged by this news, the Sentry flies into space and hurls the Void into the sun, claiming that he was no longer needed to balance out the Sentry's acts of good. The Void swears to return.
During the Superhuman Civil War, the Sentry sides with Iron Man's Pro-Registration program. He accompanies a S.H.I.E.L.D. squad to battle Wolverine and tells him that he didn't want to get involved but saw no choice; the Sentry claims that he has to stop the ugly business, even if that means becoming a part of it for a while. He then knocks Wolverine unconscious and hands him over to S.H.I.E.L.D. Later, the Sentry flies to the moon in an attempt to escape from a battle among the New Avengers, believing that every path he can choose will ultimately lead to the death of people he knows. There he is confronted by the Inhumans; believing him a threat, the Inhumans order him to follow them into Black Bolt's presence in the so-called "Blue Area" of the Moon. After a discussion of the Civil War events with the still unaware Inhumans, he rekindles his friendship with them and almost resumes his past relationship with Crystal. He is then confronted by Iron Man himself who finally convinces a still reluctant Sentry to join him. Stark tells the Sentry that his support will help Captain America, leader of the anti-Registration faction, to understand that the world is changing. Three days after the climactic battle of the Civil War, the Sentry publicly announces his support of the Registration Act. He is identified as one of the 142 registered superheroes of the Initiative.
World War Hulk
Sentry's watchtower on the top of Stark Tower is destroyed when Hulk and Iron Man first fought in New York. Mister Fantastic makes a machine that can duplicate the soothing aura Sentry uses to calm down Hulk, but the Hulk isn't fooled by it. All the while, Invisible Woman and the President try to call the real Sentry, but he ignores their pleas.
After seeing Hulk on TV deciding to force Mister Fantastic to kill Iron Man in a gladiator battle, Sentry finally decides to fly to New York to stop Hulk, remarking "It's time to play God." The Sentry arrives and engages the Hulk, starting to lose control and to unleashing his power on a level not seen before. So much energy is released during the battle that both the Hulk and Sentry revert back to their normal human states and Bruce is able to knock out Robert with a weak punch.
After the Civil War, Tony recruits Robert to the Mighty Avengers, the newest incarnation of the Avengers. He is described as the most powerful member, but is still inexperienced in using his powers. A battle against Ultron proves to be a draw until Ultron sends a virus to take down the Helicarrier before initiating an assassination of Sentry's wife.
Enraged and looking like the Void persona, Robert attacks Ultron mercilessly until Ares has to knock him down and allow Ant-Man to introduce a virus in Ultron's programming, shutting her down. Sentry, however, refuses to relent in his attack on Ultron, to the point of nearly decapitating her while the virus has not yet been completely uploaded, forcing Ms. Marvel to knock him out. After Ultron's defeat, Sentry rushes to his watchtower to find his wife alive and well. Later, Tony is shocked and terrified by Lindy's request to either depower or kill her husband.
When the Mighty Avengers confront Doctor Doom for the Symbiote attack in New York, a time machine takes Iron Man, Doom, and Sentry back to the "Silver Age". Sentry goes to the Baxter Building to retrieve Mr. Fantastic's time machine in order to return to the present timeline. After knocking out the Thing, the trio returns to the present and resumes their fight. Sentry then subdues Doom and take him into SHIELD custody.
When the Mighty Avengers investigate a Skrull spaceship that crashed in the Savage Land, they discover that inside the ship are some of the superheroes that could have been replaced by Skrulls. When Sentry battles the Vision, he transforms into the Void who tells him that the invasion is his punishment for wiping his existence everyone's memory. Sentry panics and flees to Saturn in the middle of the battle, where he deals with his fractured mind. The Skrull believe that the Sentry was most powerful of Earth's heroes and that the only way to deal with him was to induce a mental breakdown. In an attempt to destroy his fragile mind, the Skrulls invade New York, attacking the watchtower where the Sentry's wife is living. When the Skrull is about to attack, Lindy is saved by Sentry in the form of the Void. He boasts to her that whatever the Sentry could not do, he could do as the Void. After the Invasion, Sentry is approached by Norman Osborn and they discuss Reynold's mental issues. Osborn tells the Sentry that the Void was just his imagination, and that he would help deal with these issues on the condition that the Sentry join the newest incarnation of Osborn's Avengers. Robert agreed and became one of the first members of the Dark Avengers.
The first mission of the Dark Avengers is to help Doctor Doom and the rest of Latveria from an attack by Morgan Le Fay. As the Dark Avengers and Sentry arrive in Latveria, they see Doom unconcious on the floor. When Morgan approaches, Osborn tells Sentry to unleash his powers to defeat her. Sentry easily rips off Morgan's head. Sentry then wonders if what he did was right or wrong, and Osborn assures him that what he did was right. The Dark Avengers seem successful in their first mission, as they defeat Morgan and save Latveria. Sentry starts to scream and there is an explosion. After it clears, Morgan Le Fay is seen alive and the Sentry is gone. After Morgan's eventual defeat, the Dark Avengers return to Avengers Tower. There is a brilliant flash of light as they arrive and the Sentry is seen alive and well, hovering in front of his tower. Norman manages to calm down the confused Sentry.
The next time Osborn calls upon Reynolds, it is in response to an Atlantean terrorist cell's attack on U.S. soil. Reynolds is surprised when Osborn doesn't ask for the Sentry, but instead suggests that the Void is needed to kill all but one of the terrorists as an act of vengeance. "But you said there was no Void," Sentry counters, and Osborn only repeats his request for what needs to be done. As a result, the Sentry performs the bloody task, leaving doubts as to whether the Sentry was still in control, or if the Void had once again taken over.
Sentry and the Dark Avengers go to San Francisco to quell the riots that are happening between humans and mutants. When the Dark Avengers and the Dark X-Men fight against the X-Men, Emma Frost enters Reynolds' mind and releases him from the Void's control, resulting in Sentry flying away from the battle. When Emma's hold over the Void's relinquished, it chases after Sentry but leaves behind a small part of itself within Emma, trapped inside of her diamond form.
When Sentry makes his way to the Avengers Tower, his wife shoots him in the head with a ray gun. He is later seen arriving at the end of a battle between the Dark Avengers and Man-Thing in Louisiana. Sentry is then sent out to investigate an energy disturbance in a little town called Dinosaur, Colorado. Once there, he notices a man in a cowboy hat and tries to get his attention. Suddenly, his hand begins to glow black, almost as if on fire. Energy erupts from his eyes until he explodes. Osborn immediately assembles his Dark Avengers to find Reynolds.
Sentry is again shown alive, in what appears to be a high school gym. On the ground, energy continues to emanate from him. He appears to be dissolving, leaving him in great pain. Molecule Man enters and explains how he has never experienced molecules like Sentry's, before ripping Reynolds to pieces. The Sentry appears to disintegrate, but later reforms once again and confronts Molecule Man. He is able to stop Reece, force the villain to restore everything to the way it was, and then banish Molecule Man. Afterwards, he explains he realized the source of his power was the ability control molecules. Again, Osborn and the Avengers find themselves both in awe and deeply afraid of his power. After witnessing his power, Ms. Marvel tells Osborn that Scarlet Witch's mental breakdown was nothing compared to what Sentry may do.
Sentry once again seems to have escaped death when he appears behind Noh Varr claiming that Osborn needs to speak with him. A battle ensues in which Noh Varr begins to blast and throw cars at Sentry, which has little effect. Sentry claims he doesn't want to fight, but that Osborn had claimed he wants Noh Varr back "dead or alive". Noh Varr refuses to go to Osborn, claiming that the whole Dark Avengers team consists of criminals or the insane, to which Sentry responds that he, himself, is neither. Sentry is then blasted out of the sky by a girl using one of Noh Varr's weapons. He dodges the continuous assault of energy blasts and flies straight up through the clouds until a giant green explosion is seen from the ground. Sentry once again lands in the city and is soon joined by the rest of the Dark Avengers. When asked to find Noh Varr again, Sentry states that he used to have an aura which is no longer present, so he cannot.
Eventually, it is revealed that Osborn was indeed able to awaken the Void inside of Sentry, which slowly attempted to take control of his body. Claiming to be God, the Void was able to convince Reynolds to give up control of his Sentry form. Void then tries to cause massive chaos, but is reminded by Osborn that such actions could cause his own downfall, causing him to once again calm down.
It later becomes clear that the Void was Osborn's secret weapon, which he used to wipe Dr. Doom out from the Cabal since he refused to join them. Later, Sentry found out that his wife had committed suicide, although in reality Osborn had ordered Bullseye to kill her before Lester threw her out of the jet and into the ocean near Los Angeles.
Siege on Asgard
Osborn, deciding to cement his power base over America, chooses to attack Asgard under the guidance of Loki. As Osborn's secret weapon, Sentry is the first to attack the city and does battle with numerous Asgardians, including Thor. Ares becomes aware of Osborn's darker motives for attacking Asgard and turns on him. Osborn responds by sending the Sentry to defeat the War god; in the resulting fight, Sentry tears Ares in half.
After the death of Ares, Captain America and the Avengers arrive and Osborn's armor is shut down by Iron Man. In a final effort to snatch victory, Osborn orders the Sentry to tear down Asgard around them. When Osborn is finally taken down by Captain America and the Avengers, he reveals that he was the only person keeping Sentry in check. It now seems that the Sentry is merged with the Void.
The Avengers try to mount an offensive against the Sentry, but they are overwhelmed by his power. Loki, feeling responsible for all that he had done, uses the Norn Stones to reenergize the Avengers. Recharged for battle, the Avengers take the battle directly to the Sentry. Seemingly off balance, the Sentry realizes that Loki is helping the Avengers and instantly kills Loki by ripping him in half. Having lost their edge, Iron Man uses the SHIELD Helicarrier as a large bullet and rams it into the Sentry. The resulting explosion is nearly of nuclear level.
Battered and beaten, the Sentry reverts back to Robert Reynolds and asks to be killed after realizing the damage he had caused. Thor is reluctant at first and wants Reynolds to pay for his crimes. When the Void begins to regain control, however, Thor summons a bolt of lightning with Mjolnir and delivers one final blow, killing both Robert Reynolds and the Void. Feeling remorse, Thor takes the remains of the Sentry and destroys them by throwing them into the sun.
The Sentry later returns after being repurposed by the Apocalypse Twins to become a Horseman of Death. When Wolverine's crew of Uncanny Avengers eventually discover the Twin's hideout, The Sentry makes a beeline for Thor. The only person able to tell the assault was coming is Wolverine, who's heightened hearing picked up the sonic-boom the Sentry created when he began flying towards them, however he moves too quickly for Wolverine to warn Thor, and consequently the most powerful member of the team is separated from the rest by the Sentry. Sentry later explains that he isn't angry at Thor for what he did, instead saying that he understands Thor's rage at the Void murdering Loki during the Siege on Asgard. The Sentry goes on to make references to a 'Mutant rapture' and tells Thor he won't kill him because he needs him alive, stating that it's "better for humanity". Confused, Thor asks him if the Void has taken control of him, to which the Sentry replies that the Void is no longer present in his psyche, and has been replaced by Death itself.
Powers and Abilities
The Sentry is one of the most powerful superheroes in the Marvel Universe. He has personally estimated the high level of his overall power by often stating that he has the "power of a million exploding suns." Spider-Man stated that Sentry fought Galactus to a standstill, although this is a hotly debated subject due to Spider-Man's penchant for satire and hyperbole. It was later revealed that this feat was not done alone as Sentry stalemated the world eater with the help of X-Man, Nate Grey, at one of his highest points in power.
- Superhuman Strength: his strength has enabled him to overpower beings such as Ares, the Olympian God of War, with ease, destroy Asgard by flying through the foundation, easily defeat Terrax, a creation and former Herald of Galactus, and break his axe, and engage and fight to a draw an immensely enraged Hulk whose power levels had increased beyond anything seen before. That fight resulted in both individuals reverting back to human form while sentry was apparently weakened more as he was knocked out by banner.
- Superhuman Speed: Sentry possesses exceedingly high-level super-speed. This allows him to perform such feats as catching a bullet in his hand and flying from the Earth to the Sun and back in a matter of minutes.
- Superhuman Senses: It has been observed that Sentry has extremely heightened senses. This is evidenced by Sentry's statement that he could literally hear the heartbeat of a butterfly in Africa while he himself was still in New York -even when thoght, this might be an hyperbole-
- Invulnerability: Sentry is one of the few superhumans to be considered invincible. Other than his fragile mind, S.H.I.E.L.D. and even Iron Man have not been able to find any other areas of physical vulnerability. Given that he was revealed to have been carrying on an affair with Rogue, he seemed to be resistant even to her powers.
- Telepathy: According to Emma Frost, Sentry is one of the most powerful telepaths on earth. He once wiped the memory of his existence from every person on the planet. Most of Sentry's mental abilities are used to maintain his physical form.
- Resurrection: Under extreme emotional distress, Sentry can resurrect another being from death. This was first manifested when Sentry brought his wife back to life by just his touch. Originally, he was not even aware that he had this ability, and was shocked that he was capable of doing it. Sentry has not gained full control over this power, however.
- Sentry has the ability to emit a wave of radiation that can calm the Hulk down.
- Matter Manipulation: After being blown apart by the witch Morgan Le Fay, Sentry later reformed at Avengers Tower under his own power. He was again thought to have been killed when his wife shot him with one of Noh-Varr's weapons and twice was seemingly destroyed by Molecule Man. After his last apparent death at the hands of Molecule Man, Sentry came back with the realization that he could also control all forms of matter to a molecular level, much like Owen Reece. Following the revelation, the Sentry was able to use his power to beat Molecule Man with ease and then teleport him to an unknown location.
- Immortality: He firmly stated that he cannot die meaning he is for all intents and purposes immortal.
- Telekinesis: As a horseman of death, he gained the ability to move object with his mind, being able to halt Thor's Mjolnir hurled at him only inches away from his face.
During the Civil War, Spider-Man and a group of SHIELD agents ranked Sentry as the most powerful of all Earth's heroes, with the Hulk ranked as second and Black Bolt ranked as third after lossing before the Hulk (It should be noted that at this time Thor was dead, so he didn't have a place on the list). While this arbitrary ranking is at best debatable (particularly given the events of World War Hulk), the Sentry is nevertheless one of the most powerful meta-humans on the planet and has even been called a "living H-Bomb" by Norman Osborn.
In one instance he projected the Void as an entirely separate entity, a giant monster. This may suggest some form of light manipulation and the creation of hard-light constructs, but should more likely be attributed to his control over matter.
As the Void, Robert has an even more diverse set of powers. It is thought by many that Robert is even more powerful as the Void than he is in his Sentry incarnation.
Earth-2149: Marvel Zombies
The infection started with an attack by an zombie version of Sentry from an alternate universe. He began eating those who were ascending into heaven until Ash confronted him and shot him in the face using his shotgun. Unfazed, Sentry punched Ash so hard that he ripped through the fabric of reality, sucking both Ash and Sentry into the Earth-2149 universe. Warped into New York City, Sentry started looking for food. His first victims were the Avengers consisting of Colonel America, Luke Cage, Hawkeye, Black Widow, and Ms. Marvel, the first heroes at the scene of the crash site. Within a short time, the virus had reached almost every superhuman in the world. What happens to this Sentry after the world is consumed is unknown, but he may have opened another hole in the fabric of reality and escaped.
Later another man called Robert Reynolds, a powerless version from Earth 2149, appears as one of the few survivors alongside the acolytes. Black Panther, another uninfected hero, gives him the Wasp's head and tells him to be cautious or else he could be bitten. Years later an older version of Bob returns to earth in Marvel Zombies 2. Wasp appears, as well, on a suit designed by Bob which would later be used by Hawkeye.
When the Marvel Zombies attack the Hulk, he reverts to Bruce Banner and is put under analysis by Bob. It is later revealed that Robert and Forge used the body of T'Challa's son to host Colonel America's brain. This causes an attack on both by Black Panther, but he is stopped by the new Colonel, who almost killed him before being stopped by Bob. When the zombies return, the heroes, now with zombie Spider-Man and zombie Luke Cage on their side, fight the zombies in order to prevent them from entering the space ship where the last humans remain.
While repairing Luke and Spidey's injuries, Bob kisses Wasp and tells her how he truly feels about her. To the other heroes' surprise, Wasp's feelings are similar.
While on watch, Bob is attacked by the zombie Bruce Banner who had somehow managed to escape from his prison. The attack makes Bob to accidentally open the force field, but he eventually escapes. The zombies realize their hunger is gone, but this revelation is soon interrupted by an attack from zombie Hulk, who attempts to feed on the humans. Though his fellow zombies try to convince him to stop, Hulk doesn't listen and a fight begins once again. Though the zombies fight valiantly, Hulk starts to gain the upper hand and kills Firelord, Iron Man, Phoenix, and Hawkeye. After their deaths, Bob arrives and sacrifices himself to the Hulk. Black Panther tries to stop him, but Bob says that it's the only way to stop Hulk, and that he has no reason reason to live anymore since he believes Wasp was killed by Goliath. After devouring Bob, the zombie Hulk reverts back to Bruce Banner who asks for the others kill him. The zombies agree in order to avoid another attack on the humans. Goliath is seen with the remains of Wasp, only a head now, and asks for her forgiveness. Wasp answers by saying that Bob was the greatest man she ever knew and that he cared for everyone equally. Goliath answers "You always knew how to make me feel small."
