X VS X Because Mario/Sonic fights are always popular lol. Anyway, these two are pretty much considered the muscle bound douchebags from they're respective universes. I'm thinking a multi-round battle here. Round 1: Treasure hunting contest. 20 bags of money are hidden throughout a warehouse. Whoever finds the most money wins the round. Round 2: Golf cart race around a race track for 30 laps. Whoever finishes first wins the round. Round 3: All out fight. Whoever beats the other wins the round. Whoever wins the majority of the rounds wins the match.
