Sentry (Robert Reynolds) - Fictional Character Biography - Dark Avengers

Dark Avengers

Sentry joins the Dark Avengers, Norman Osborn's personal team of Avengers, stating that Osborn is helping him in return after Osborn confides his own mental deficiency in Bob. Upon confronting the sorceress Morgan le Fay, the Sentry kills her only to have her respawn and kill him in turn. After the Avengers and Dr. Doom defeat Morgana, the team returns to New York City to find the Sentry reappears alive and well. After a terrorist attack by an Atlantean cell, Norman Osborn demands to speak to the Void and tells him to kill all the terrorists. The Sentry obliges but is seen with black eyes, indicating the return of the Void within the Sentry persona.

When riots break out in San Francisco, the Dark Avengers and HAMMER move in to contain the situation. The Sentry watches as the riots are quelled, when the Dark Avengers team up with Norman's Dark X-Men against the X-Men, Emma Frost frees the Void from Sentry to take him off the battlefield. However, a sliver of the Void becomes contained in her mind, forcing Emma to shift into her diamond form to keep it contained. When Psylocke, Professor X, and Cyclops attempt to help Emma, she subsequently passes the Void sliver to Cyclops, whom the Void felt could be of more use to it. However after years of dating and being married to the world's most powerful mutant telepath, Jean Grey, Cyclops uses all that she taught him to successfully lock the Void inside an unbreakable psychic prison within his own mind.

When Sentry returns to Avengers Tower, Lindy shoots him because she fears his mindset, but he returns unharmed.

The Avengers are sent to investigate disappearances in Dinosaur, Colorado, and the Sentry is disintegrated when he approaches the area. The team find that Owen Reece, the Molecule Man, secluding himself, is responsible. Reece is losing touch with reality, and struggles to differentiate between the real and his creations. After the other Dark Avengers have been defeated, Osborn's aide Victoria Hand convinces Owen to restore reality in order to be left to his own devices. The Sentry returns mid-conversation and attacks Molecule Man only to be destroyed again. The Sentry reforms once more, but this time under the Void's influence. When a missile distracts Owen, Sentry takes control of Reece's body and tells Owen to restore reality or die. Reece seemingly obliges him, but is killed, which causes Bob/Void to believe they cannot die. Bob regains control of his body, but doesn't seem to recall killing Molecule Man. Ms. Marvel muses that the Scarlet Witch's reality-rewriting nervous breakdown was negligible in comparison to the threat if the Sentry would lose control.

Sentry finds a runaway Noh-Varr in the streets of Manhattan. A battle breaks out and Sentry is distracted when a girl named Annie uses one of Noh-Varr weapons. This creates enough time for Noh-Varr to get away.

After shooting Robert, apparently killing him, Lindy records the Sentry's origins as a drug addict (previously revealed) and that he found the Professor's super serum by accident. After drinking the serum Bob destroyed the lab, killing his partner and two guards. As the Sentry, Bob lives a hero's life, forgetting about his past as a thief and addict, blaming them on "a boogeyman" that would become the Void. Lindy knew that Osborn's orders and replica of the serum were unlocking the Void again (Osborn calls him "his secret weapon"). When Bob recovers, his Void persona tries to kill Lindy while claiming to be Galactus, only to be stopped by the Sentry one, who tries to destroy the Void (and himself) in the Sun, only to survive and be convinced to return home.

Upon his return, the Void has now taken control of Robert's body. With black tendrils raining from the sky, the Void severely damages multiple buildings, killing some innocents. As the Iron Patriot, Osborn flies to the Void, claiming that he was breaking their "deal". Norman then has Bullseye murder Lindy.
