Waluigi

Waluigi is a character introduced in Mario Tennis as Luigi's rival. In Super Smash Bros. Brawl, Waluigi is an assist trophy. When Waluigi appears, he stomps opponents into the ground, then continues with a barrage of kicks. He then finishes with either a powerful kick, or a swing of his tennis racket. Luigi in Brawl can color swap to a color like Waluigi, just like Mario in Melee he could color swap to Wario's color.
