Wapeach Has Been Revealed!
Waluigi, one of Nintendo’s most meme-able characters, did not make his first “WAH” until 2000, when Nintendo was developing Mario Tennis for the N64 and needed an extra character for Doubles matches. Someone suggested making a Wario equivalent for Luigi and giving him a pun name based on the Japanese word “igiwalui” (loosely translates to “a bad person”). Miyamoto had no involvement beyond final approval, so if he didn’t like it, the world might have never seen Waluigi, but he fortunately loved the concept.
