Mario during each arc of YGO that he had some involvement in:
Duelist Kingdom: Busy managing the plumbing for said Kingdom. Isn't aware of the whole People's souls getting imprisoned thing.
Dungeon Dice: Accidentally flooded Duke's house, courtesy of a VERY iffy plumbing issue
Battle City: Qualified and swept the duels he was involved in, but had to excuse himself from the tournament due to unresolved plumbing issues, back at his and his bro's work place.
Orichalcos: Still working on said unresolved plumbing issues. Did someone plant a bomb in the pipes?? Got challenged to an Orichalcos duel, off screen, which he won, handily. Kinda got confused when his opponent lost their soul, though... Also, he ATE THE LEVIATHAN-
KC Grand Championships: Qualified again, but for the same reason as Battle City, had to excuse himself due to unresolved plumbing issues.
Dawn of the Duel/Zorc: Note to self; evil dark dragon gods don't taste that good.
