One thing to keep in mind for this ongoing game is that besides marketing (and occasionally favorites like Velma), some characters initially get in over others for practical reasons (while Morty
did get in before Rick, both were still announced together), so it's really a case-by-case basis.
Meanwhile, in NASB, the staff mainly lobbies for characters that are interesting/they or the fans like, since there's no guarantee that it'll have a long support cycle.
On a lighter semi-related note, Harley's spin-off got renewed for another season.
As cool as Gwen and Vilgax would be, I don't think they'd pass over Ben when he's the one with all the requests.
This.
And no, the what-if episode in which Gwen had the Omnitrix is not an excuse, either, before anyone brings that up.
is that counting the times wil.e appeared without the road runner? cause i don't the road runner ever did so i'm not sure they should be even
It's...hard to say, actually. Though it does help that when Road Runner doesn't appear with him, Bugs Bunny is there instead, I guess.
