The end of 2021 was eventful for the mascot platform fighter scene across the board. As Super Smash Bros. Ultimate was ending with the release of Sora as its final fighter, Nickelodeon All-Star Brawl stepped into the ring, but sadly did not last very long in the spotlight due to lack of content and being fairly buggy. Shortly after that Warner Bros. announced MultiVersus, another mascot platform fighter drawing on the extensive catalog of IPs at WB's disposal like Batman, Shaggy from Scooby-Doo, and Finn and Jake (as separate fighters) from Adventure Time. In its last major announcement, Nickelodeon All-Star Brawl confirmed voice acting was coming to the game.
