The MultiVersus meme phenomenon stems from the chaotic crossover nature of the Warner Bros. Discovery platform fighter, which famously pits characters like Shaggy from Scooby-Doo against heavyweights like Superman or Arya Stark. The most iconic trope within the community is 'Ultra Instinct Shaggy,' a fan-created power fantasy that became so popular the developers officially canonized it in the game's marketing. Memes often focus on the absurdity of these matchups, the game's rocky release and relaunch cycle, or the anticipation of leaked characters joining the roster. It serves as a digital playground for crossover enthusiasts who love seeing disparate worlds collide in the most nonsensical ways possible.
