Eventually the Reaper joined forces with Kang and Ultron-59 and their "final battle" with the Avengers. Billy appeared to be friends with this future's Oddball and the two discussed Billy's desire for revenge against his brother and father. Billy and his brother were locked in battle until their father, the Vision, destroyed Ultron, ending the fight. As the Vision lay dying, he implored Billy not to give up on humanity the way he had when Wanda was killed. What exactly became of Billy following the Avengers' victory is unknown. Unlike Earth-616, Tommy inherited their mother's mystical abilities and the nature of Billy's powers were unspecified. As the Grim Reaper, Billy wielded a scythe of unknown nature, either technological or mystic, that could teleport back to him if it left his hand. The scythe could presumably cut what he wanted it to while harmlessly phasing through what he did not, such as when he impaled Jessie Wingfoot without injuring Ultron-59. During the battle with Tommy, his scythe was able to deflect mystical force bolts conjured at him. During "Battle of the Atom", Billy is seen as a member of the future X-Men who travel back in time to stop a group of impostors led by Beast. He is the Earth's new Sorcerer Supreme, and possesses the Eye of Agamotto. In the "House of M" reality, Wiccan and his twin brother are the twins of Wanda Magnus.
