Waluigi first appeared in Mario Tennis in 2000 as Wario's doubles partner and a rival to Luigi, created to give Wario a counterpart in Nintendo's Mario spin off games. Voiced for many years by Charles Martinet, the character became known for his lanky design, purple outfit, mischievous cackling and drawn out vocalisations. Online, clips of his yells were isolated for soundboards and edits, where the elongated name call summed up his theatrical, attention seeking personality. It remains popular in gaming memes because it is instantly recognisable even without any visuals.
