History
Wonder Man was a member of the Underground founded to defeat Hydra's Captain America. When Iron Man understood that heroes needed the fragments of the Cosmic Cube, they traveled around the world for them but discovered only two of them. The evil Steve attacked the Underground and stole the fragments. While "Cap" did this, Simon fought Hulk. It's unrevealed if Wonder Man was present when the heroes' triumphed against Hydra.[1]
