Despite Waluigi's popularity gain as an Internet meme, he has yet to appear outside of "Mario" spin-offs, most notably being his lack of playability within "Super Smash Bros. Ultimate" (confirmed when the character was announced as a non-playable Assist Trophy during E3 2018), which was met with negative reception from the gaming press and social media, with websites such as Reddit and Twitter leading the outcry; online Change.org petitions have been created in support of Waluigi being added as a playable character, garnering thousands of supporters. IGN's Joe Skrebels described his non-playable status within the game as "...a slap in the face for those who want a playable Waluigi."
