Wario

Wario first started off as an antagonist in the Mario games, but since then has sprouted his own games such as Wario Ware Inc. for the GBA, and Wario World for the Gamecube. He quite often makes cameos in non-traditional Mario games like the Mario Sports series.

Wario is known to be evil and real greedy. He's also famous for his bizarre behaviour, which is much more exploited in games themed after him like the Warioware series.

At E3 2006, it was announced that Wario will make his Super Smash Bros. debut in Super Smash Bros. Brawl for Wii. Not much is known on his moveset, but he will wear his costume from Wario Ware. It isn't confirmed whether the 'fart attack' shown in the trailer will be in the final game or not.
