Suggested by Destroyer Ultron has obtained many forms and abilities over the years. His latest one is the Sigma mode from Marvel vs Capcom 4. Despite this the match is close since Colossus obtained a fraction of the Phoenix Force a while back. That gives him a pretty big boost in combat. It won’t be enough to overcome Ultron’s speed or array of energy abilities but it will make this a real match. Ultron wins.
