Reddit user hugeleakeractually, who originally leaked the upcoming free-to-play Smash-esque fighter MultiVersus, made a new post mentioning a number of other potential upcoming characters.
The post contained two separate lists of characters potentially coming to MultiVersus. The first set, which were confirmed via datamining, are apparently mostly finished and practically guaranteed to make an appearance at some point in the games life.
Joker – DC
Raven – DC
Gizmo – Gremlins
Marvin the Martian – Looney Tunes
Lebron James – NBA
Rick – Rick and Morty
Morty – Rick and Morty
Scooby-Doo – Scooby-Doo
Daenerys – Game of Thrones
The Hound – Game of Thrones
Wicked Witch – The Wizard of Oz
Godzilla – GodzillaReddit
The second list includes some rather unusual characters, some of which might not happen over licensing, with a vague explanation of what to expect.
Johnny Bravo – Johnny Bravo (he was in the initial pitch and had work done. He will come eventually)
Fred Flinstone – Flinstones
Mad Max is on hold last I heard. Not sure if it was an IP related issue. Same with Harry Potter who is definitely on hold (not sure if any development was ever even done).
Here’s a few more characters I can confirm that are very likely to be coming:
Samurai Jack – Samurai Jack
The Powerpuff Girls – Powerpuff Girls (all one Fighter)
The Animaniacs – The Animaniacs (also all one fighter as far as I’m aware)
Duck Dodgers/Daffy – Looney Tunes
Scorpion – Mortal Kombat
Ben 10 – Ben 10
Ted Lasso – Ted LassoReddit
Like anything, things could change at the drop of a hat, like the countless times Ash was confirmed for Mortal Kombat despite it not happening, but it does suggest a strong commitment to the fighter long term.
