Mario was made by converting Nintendo's model from Smash Bros. Brawl to male basic. I then worked in some parts from some of their other games and made some new ones. I resized all the portions and brought in a cape from Ren's Superman. I also gave it Ren's Superman keyframes since they seemed the closest match to Mario's moves.
The bug is on the knuckle covers which drag though it's more noticable in CTool than in game.
