Wario hosts Wario Ware: Smooth Moves, and now invited Miis to play, despite their rivalry. This is the Miis and Wario's first appearance together.
Wario meets the Miis for a second time at Mario and Sonic at the Olympic Games.
Wario is in this game, and so are Miis, but only in the extra zone. Wario frequently likes to bully the Miis at the Star Carnival.
