My vote is for colossusBecause he is been like this since the beginning and no one in the whole universe (except Seatin) uses him.....Venom pool is good on his own because of regen,power flood(not sure),health block and bleedDuck is also pretty good with armor,thundershock,regenIron patriot gives regen ,stun and power floodMs. Marvel fury stacks are insane.Old man logan berserk ability is useful as it increase his damage ......SO IT IS COLOSSUS FOR ME.....Hope u all agree with thisMy 5* colossus is dupped and is of no useðŸ˜ðŸ˜ðŸ˜ðŸ˜ðŸ˜
