Eden was selected as one of the many unregistered superhumans, hand picked by Nick Fury, as part of his Secret Warriors and under the tutelage of Gateway. Initially, Fury attempted to recruit him to another unknown team, but Gateway refused.
After joining the team Eden went on several successful missions with them. On a particular mission where his powers were key in the team's escape he was badly injured. The team barely made it out alive, and Eden was left in a coma. He worked with the Secret Warriors after that.
Eden was recruited into the Avengers after the the conflict between Earth's Mightiest Heroes and the X-Men. Together with the other new recruits, he traveled to Mars to rescue the original team and fight Ex Nihilo.
When the Avengers fell under S.H.I.E.L.D. authority, Manifold was one of the members who left, and joined A.I.M., now under the leadership of Bobby da Costa.
