Fan Casting Reaper

In the late 1930's a mercenary named Eric Wayne was hired to kill Captain America by Hydra. After failing he was given a second chance and sacrificed himself to save Red Skull. After falling into a super collider Eric was given cosmic powers but was dying and so Baron Strucker saved him by experimenting on him with the space stone which gave him limited immortality. He then went to fulfill his mission and kill Steve Rogers but was taken down and remained in the plane that Steve Rogers, Red Skull, and him were all frozen in. Eventually sometime in 2015 he was freed from the ice by a still unknown person. After trying to kill the Avengers he was taken down and imprisoned by S.H.I.E.L.D. He remained in this prison until Super-Human War I of 2018. After the war the timeline was changed by the East Coast Avengers using the time stone. Now Eric is free, the brother of Simon Williams, was born some time after Simon, and is named Eric Williams. Even though these things have changed, the stuff that happened with him and Steve Rogers did happen but no one remembers it. About more than 20 years into the future in a dark version of the timeline where Eric is still the Reaper he follows Lucas Bishop to the past where he is stuck as an recurring villain for both the X-Men and Hawkeye. Now there is a good Eric Williams who is a part of the X-Men and an evil Eric who was a part of Intelligencia and the two are destined to meet and one of them must kill the other.
