Obviously this show already has a huge cast and it… honestly kinda has its biggest issues drawn from that, but nonetheless it will expand its catalog of heroes and villains every season in exciting new ways. What characters do you think we’ll see? Or see more of?
Personally, this is who I think could appear, at least briefly:
Jason Todd as Red Hood
Harper Row as Bluebird
Cisco Ramon as Vibe
Dolphin as… Dolphin
Wendy Jones as Windfall
Off the top of my head, those are the characters I think we’ll see that are already in the show. We’ll probably see who is most definitely Damian Wayne as a child, but he won’t be a major character still, especially not Robin.
As for new characters completely, that’s, of course, hard to say, but I’ll take a guess at:
Those are admittedly the only Legionnaires I know of off-hand. And no, I don’t expect all of them.
As for other completely new characters, I’ll let you all guess. I can’t think of any hinted-at characters right now. Don and Dawn maybe? I don’t think a time skip would be that long for them to make sense, though.
