Waluigi

Luigi's purple nemesis shares the green good guy's strong abilities across the board. In fact, Waluigi even improves on Luigi in some respects. His karts, too, are some of the craziest around. Waluigi is known to be sneaky; he is a big Bob-omb thrower! In Mario Kart Wii Waluigi has good drift and accelaration stats making him good in Grand Prix and VS.
