History
Little is detailed about Bobby's life before the zombie plague arrived on Earth-2149, however it can be presumed that it followed much the same path as Iceman of Earth-616.
Presumably, Bobby was at the Xavier Institute when it was attacked and arrived at the S.H.I.E.L.D. Helicarrier with the other X-Men and Magneto.
With the extremely varied bunch all assembled on the Helicarrier, Nick explaind how serious he believed the situation to be; that it was the end of the world. He also explained that whatever the histories of those assembled, they were all on the same side.
It can also be assumed that he was part of the team sent back down to the surface to battle the zombies, unsuccessfully,[1] it would seem, as when Beast and Reed Richards find a sizable stash of meat in Latveria and the surrounding area, a zombified Iceman and a huge horde zombies head off to lay siege to Castle Doom. Unable to gain access to the fortress, Bobby got attacked by the re-animated corpses of the Deadite Legion, although he ultimately survived the attack.[2]
Later, he tried to feed on Dr. Betty Swanson. While Headpool unsuccessfully tried to convince him to give up on his addiction to human flesh, this was revealed to be a distraction as the main universe's Deadpool barged in on a motorcycle and pinned Iceman against some loose debris, leaving him to fruitlessly scream for help.[3]
