Deadpool's life mirrored that of his Earth-616 counterpart up to the point where the cannibalistic symptoms started appearing in infected hosts.
Becoming infected in an unknown period of time, Deadpool was turned into a cannibal and stayed in New York. The Punisher has hunted and killed him various times, but due to Deadpool's healing factor, he always comes back for another round with the vigilante. Punisher decided to bury him in pieces scattered across the city, but it also failed.
When Punisher was at his hideout with the priest and the child, Deadpool arrived and called for Frank, which got him gunned down. After Deadpool was crucified onto a wooden board with knives by Punisher, he told him about Patient Zero's proposal and that he was already there. When Punisher decided to go out and kill the King of Death and get Spider-Man's mate back, Deadpool, along with Black Widow and Scorpion, joined him on his quest.
Upon arriving, the group was ambushed by cannibals sent by the King of Death, resulting in them getting captured. Deadpool was locked in a cell and after regretting naming himself Deadpool and trying out Ratmeat, he killed Red Skull (who got too close) and escaped. He got Frank's bag of guns and started killing some cannibals present.
His ultimate fate is unknown, but was presumably killed when Punisher threw grenades at him when Wade was fighting Hammerhead.
