Like other platform fighters such as Super Smash Bros. Ultimate and Nickolodeon All-Star Brawl, MultiVersus has a roster with plenty of crossover potential. Combining characters from all of Warner Bros' IPs, MultiVersus already has a wacky roster so far, even with only 16 being available so far. However, with so many potential fighters that could be added to MultiVersus, fans are often speculating on what new characters will be brought to the game next.
