Currently in Closed Alpha, ‘MultiVersus’ is a 2v2 fighting game that uses all manner of characters from properties owned by Warner Bros. This means you can currently have matchups that involve Wonder Woman taking on Shaggy from Scooby Doo, or perhaps Jake and Finn from Adventure Time battling it out against Arya Stark from Game of Thrones and Tom & Jerry. A datamine, however, has revealed multiple characters that could be coming to the game in the future.
