Due to Nintendo's continued lack of attention towards Waluigi, Did You Know Gaming takes a look at some facts, secrets and Easter eggs relating to Waluigi! Waluigi first appeared in Mario Tennis on the Nintendo 64, and has since been a regular character in Mario spin-off titles including the recent Mario Tennis Aces. Waluigi also has a strong connection to Wario, and often appears alongside him as a pair, but not in Super Smash Bros Ultimate... We personally are hoping for a Waluigi game, or even Waluigi games in the future.
