Mario & Sonic at the Olympic Games

Waluigi is a fictional character in the Mario series of video games. He accompanies Wario in spin-offs from the main Mario series, oftentimes for... the sake of causing mischief. He was created by Camelot employee Fumihide Aoki and is voiced by Charles Martinet, who describes Waluigi as being someone who has a lot of self-pity and would "cheat to win." Waluigi was created by Fumihide Aoki and is voiced by Charles Martinet. His name is a portmanteau of Luigi's name and the Japanese adjective warui meaning "bad"; hence, a "bad Luigi". Martinet stated that the cornerstone of Waluigi's personality is one of self-pity, a character who feels that everything goes right for everyone but himself. As displayed in Mario Power Tennis and Mario Hoops 3-on-3, Waluigi features the ability to summon a body of water and swim towards each game's respective ball, which IGN editor Rob Burman describes as baffling. He is the same age as Luigi, and wears black overalls, a dark purple shirt, and a dark purple hat with a "Γ" symbol.
