Waluigi is a 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. He was created by Camelot employee Fumihide Aoki and was voiced from 2000 to 2022 by Charles Martinet, who described Waluigi as someone with a lot of self-pity. Waluigi's design is characterised by his tall stature, thin and lanky frame, and his purple and black outfit with purple hat, which displays an inverted yellow "L".

Charles Andre Martinet is an American actor. Martinet created the voices of both Mario and Luigi in the Super Mario video game series, portraying them from 1994 to 2023. He also voiced other characters in the series such as Wario, Waluigi, and the baby equivalents of Mario and Luigi, prior to stepping down as voice actor to become an official brand ambassador for the series.
