Powers/Abilities: Bathed in "stasis fluid" (a fluid filled with billions of nano-sized replicator and assembler robots) and injected with various other unidentified fluids, Biohazard was able to add, assemble and replicate any DNA it consumed. It instinctively reproduced any useful attributes of specimens it consumed and by consuming a victim's brain additionally gained the victim's full memories. The nanotech not only enabled Biohazard to shapeshift, but also allowed it to reproduce asexually. Unfortunately the severe damage originally inflicted to Kelly's brain and the consumption of various brains (and therefore their memories) left Biohazard confused and unsure of its own identity. With the added nanotechnology Biohazard was left with an urge to consume anyone that led it closer to regaining John Kelly's full memories.

  Biohazard's offspring was oblivious to the fact that it was merely a split-off pawn of Biohazard and not really in control of itself. With Biohazard's memories hidden in its subconscious the offspring looked and acted like Biohazard's creator William Hansen. Biohazard was able to suppress Hansen's personality at will and accelerate its own growth to shapeshift into a more dangerous form. This process was irreversible.


(Marvel Comics Presents I#62/4 - BTS) - The computer controlling the Deathlok cyborg electrocuted John Kelly's brain when Kelly tried to resist the computer's commands.

(Deathlok I#1) - Kelly's brain was removed from the Deathlok cyborg and Hansen asked if he could keep it. Nobody cared and Hansen took it with him.

(Deathlok II#13-14 (fb) ) - Hansen put Kelly's brain into a bath with "stasis fluid" to see if the technology could repair and revive John Kelly.

(Deathlok II#14 (fb) ) - Hansen made additional experiments with Kelly's brain, but eventually the lack of results made Hansen toss it into the garbage.

(Deathlok II#13-14 (fb) ) - Disposed of at a garbage dump the brain was repaired by the nanotech fluid and nourished itself with whatever garbage it could find including rotting food and tumorous cells from biopsies. Eventually the brain became strong enough to hunt for itself and killed a cat that tried to drag it away. Reproducing the most useful attributes of the cat Biohazard continued to hunt and soon killed the dump's security guard. With the guard's memories and body Biohazard was ready to hunt for his past.

(Deathlok II#15 (fb) - BTS) - Before leaving the dump Biohazard shed some skin to appear more human.

(Deathlok II#12 (fb) - BTS) - Biohazard consumed the brain of a S.H.I.E.L.D. agent named Eddie.

(Deathlok II#12) - With Eddie's knowledge Biohazard went to SHELD's records room where Harry Angstrom went through Deathlok's files. Biohazard attacked Harry and consumed his brain. Looking at an image of Deathlok Biohazard tried to remember if it had once been Deathlok and decided to learn more about Deathlok.

  With Angstrom's knowledge Biohazard continued his search for his true identity and killed an unidentified woman. It was sure that it had to eat Deathlok's brain to remember everything.

(Deathlok II#13) - Biohazard went to a cemetery in Brooklyn, New York to dig up Hansen. When a guard confronted Biohazard it decapitated the guard with one slash. After digging up Hansen Biohazard consumed Hansen's brain and gained new fragments of his origin. Biohazard wanted to talk to Hansen and began to regrow Hansen's body inside it.

  When the body was regrown completely Biohazard puked it out. The reborn Hansen had all the original's memories, but was infected with Biohazard's DNA, which slowly grew inside him.

(Deathlok II#15 (fb) ) - The parent Biohazard body went into hibernation after the birth of its offspring and was found by the police. Regarded as shed skin S.H.I.E.L.D. picked up the lifeless Biohazard and examined it. They learned that Biohazard's DNA once belonged to John Kelly and created a nanotech inhibitor to fight Biohazard.

(Deathlok II#14 (fb) - BTS) - Meanwhile with Biohazard's DNA slowly growing inside Hansen's new body Hansen felt compelled to go to Deathlok (Michael Collins) to tell him about Biohazard. This Biohazard's actual mission was to consume Deathlok's brain.

(Deathlok II#14) - Hansen visited Michael Collins' home where Collins as Deathlok was with his wife, child and sister-in-law. Though Deathlok was surpised that Hansen turned up alive, he listened to the former Cybertek employee, who told him everything about the creature Biohazard that grew from John Kelly's brain and wanted the complete back up of Kelly's memories, that was stored in the Deathlok cyborg's new brain. Suddenly Hansen realized that coming to Collins made no sense at all and Biohazard took over and attacked Deathlok and his family. Unable to kill the monster Deathlok told his family to flee, but his wife returned to give him his gun and was caught by Biohazard.

(Deathlok II#15) - After tackling Biohazard to safe his wife, Deathlok was beaten down by the monstrosity, but it was stopped short from consuming his brain by S.H.I.E.L.D. Agent Earl Angstrom, who attacked it with a Mandroid armor and used a nanotech inhibitor created through knowledge gained from Biohazard's shed skin to temporarily block Biohazard's shapeshifting ability. Angstrom and Deathlok then forced Biohazard into an unbreakable Adamantium canister.

(Deathlok II#15 - BTS) - The alleged skin came to life and escaped S.H.I.E.L.D.'s Helicarrier after killing several S.H.I.E.L.D. agents.

(Deathlok II#15) - The parent Biohazard body continued his mission to reunite Kelly's family, not knowing that his second body had failed to consume Deathlok's brain. Biohazard found Kelly's wife Karen and daughter Sara riding horses in Central Park and attacked them, but Deathlok and Mandroid (Angstrom) came to save them. They immediately realized that the parent body was too big for their Adamantium barrel. Unfortunately for Angstrom it also seemed immune to the nanotech inhibitor. Still planning to consume Kelly's family to be with them again, Deathlok approached Biohazard slowly and tried to reason with Kelly. The monster stopped his assault on Kelly's family for a second and Deathlok took the opportunity to attack the monster, cut it open and rip out Kelly's brain. Deathlok then tossed the brain into the Adamantium barrell and the parent Biohazard body dropped dead because without the brain it couldn't regenerate anymore. Angstrom burnt the body with a blast from the Mandroid armor.

Comments: Created by Dwayne McDuffie, Denys Cowan & Mike Manley.

And John Kelly was still not dead because his memories were still stored inside the Deathlok cyborg and he eventually escaped the cyborg by taking over one of the Cyberwarriors to become SIEGE. Never heard of him? Come on! He was a member of the Initiative's Florida team the Command until he they were attacked by zombies in Marvel Zombies 3#1.

BTW isn't it ironic that Hansen, who had tossed away the brain like garbage, was eventually used by it as a pawn....sure it wasn't the real Hansen anymore, but at least it thought it was. Hansen's first death wasn't much better either as it was caused by another Cybertek creation--Warwolf.
