So all heroes some from the fan have made it in, so any of these...
Luke Cage (modern)
Multiple Man (Classic)
Team X Wolverine
Iron Man 2020
Hydro Armor Iron Man
Bulked up grey hulk
Extra rocky mutated thing
I think a Sue (blue/black costume) or Johnny or both are likely and I would love an ionic purple wonder man
Wave 2 did not do any characters they did in wave 1 if they do the same here out of the fan poll that would leave just luke cage & mutliple man
