Marvel Comics Mini version of Zombie Deadpool (Wade Wilson) designed in fusion 360
Little is detailed about Deadpool's life before the zombie plague arrived on Earth-2149, however it can be presumed that it followed much the same path as his Earth-616 counterpart.At some point he was infected, and attacked the Silver Surfer. He most likely fled the attack but also escaped the Power Cosmic zombies from getting himself incinerated and killed. He later transported from Earth-2149 to Earth-616, calling himself the Merc with half a Mouth (due to his lack of most of his jaw) and exhibiting a wide range of knowledge, which he used to take out Jennifer Kale's magic, and then attacked her. He appears to be killed when Wundarr the Aquarian threw him and Kale retaliated by luring Deadpool into the blades of a nearby skiff, completely tearing him apart. However, as the Prime Carrier he was contained within A.R.M.O.R.. Deadpool, now reduced to only a head, managed to escape from A.R.M.O.R. Headquarters with the help of Simon Garth by using the base's teleporters to escape to the bottom of the sea, where Deadpool's head infected all of the Men-Fish. Garth was compelled to travel to the island nation of Taíno in the Caribbean Sea, where he told Black Talon about the zombie plague. Black Talon assumed control of Garth, and captured Deadpool's head. However, Deadpool soon escaped with the help of Garth after biting one of Black Talon's guard.
