Waluigi[a] is a fictional character in the Mario franchise. He plays the role of Luigi's arch-rival and accompanies Wario in spin-offs from the main Mario series, often for the sake of causing mischief and problems. He was created by Camelot employee Fumihide Aoki and was voiced from 2000 to 2023 by Charles Martinet, who described Waluigi as someone who has a lot of self-pity and would "cheat to win".
