Going off of the Multiversus leak yesterday here’s my prediction for the roster within the first two seasons, from launch to characters added in each season.
We have Joker, and Banana Guard, so I’m thinking next few are going to being:
Jason- the other secret character, Warner owns the games, and with the Jason Universe account popping up, it feels too coincidental. If not him, it’s Johnny Bravo, but CN likes to forget about for no good reason, so I could see them make the devs add him later.
Beetlejuice- second or third season will take us through Halloween and we already know he’s coming. Eric Bazua also teased he’s voicing him. Plus the sequel makes it the perfect time.
-Wicked Witch, but extension of the same deal as Beetlejuice, they likely come at Halloween to promote the second part of Wicked.
-Barbie, one of the biggest movies in a long time for Warner, it’s a matter of when, not if for this one. But that when may not be early on.
-powerpuff girls and Dexter, with all the focus on their stages, and there even being unique boss fights with them. Plus jokers trailer confirms the former, if they are not at launch, they have to be coming soon after.
-Daffy Duck, plenty of teasing, iconic, new movie coming out, perfect timing.
—Marceline, I think the reason we have Banana guard Is because they already finished working on Marceline last year when they were teasing here. She will either be at launch or season 1. No reason to hold her off, especially after the controversy caused by BG.
And that’s about it for what I’d consider guarantees within the first few seasons here. A fair amount of popular choices, with a few unexpected ones that fans might actually really like.
