I know it isn't perfect (I just don't see Toad or the Baby Mario Bros. working, I'd love to be proven wrong though) but I tried to include as many characters as I could without going overboard (hence some of the alternate costumes). And I will admit to not knowing hardly anything about Pokemon so that's what the free space is for. And I really couldn't think of a better Mario series boss.
Have fun tearing it to pieces!
