Unus worked for Apocalypse
and was sent into Old New York City to search for remaining humans how lived there and to destroy them. While on a mission for Apocalypse he encountered a human girl and Bishop, who resisted him. He then ordered his Infinites to destroy both the girl and Bishop when the X-Men
showed up and attacked the Infinites and Unus. During the battle Unus managed to sneak up on Magneto
with a plastic gun and threatened to kill him. However before he could kill Magneto, Iceman managed to freeze him before he could get his shield up. Iceman then smashed the frozen Unus into pieces, killing him.
