There are the only 2 guys from The Avengers that translate well to a hockey jersey (in this blogger’s humble opinion): Captain America and Iron Man. I actually made one for Thor, but it looked weird. You just need to buy a plain green practice jersey for the Hulk.
These are rather generic-looking and could possibly be offered one day (would need to dispose of the S.H.I.E.L.D. logo). Unless Marvel trademarked the American flag, amirite??
