Waluigi debuted in Mario Tennis in 2000 for the Nintendo 64, created as Luigi's lanky rival and Wario's partner in doubles. Voiced for years by Charles Martinet, the character became known for theatrical taunts, dances and an exaggerated evil laugh across Mario Kart, Mario Party and sports spin-offs. Clips of the cackle spread through gaming edits and meme soundboards because it is instantly recognisable in under two seconds, making it a shorthand for smug, cartoon villainy even outside Nintendo fandom.
