The Shredder is a man who goes in a suit…..nope. Actually he’s a little red alien who goes in a suit and than goes in another suit. Hmmmmmm. Captain America is a super soldier so all of his skills are slightly higher than a human’s. Or at least they should be. The Shredder has a magic thunder sword so that gives him the edge. Shredder wins.

Update Captain America’s Nova form definitely takes the win here.
