I do hope we get at least a few new series represented as well.
Seeing the new characters being Jimmy, Squidward, Raphael, and Vlad, I would also assume Donatello and Zuko are pretty surefire choices as well.
Obviously the biggest missing series here remains to be The Fairly Oddparents... maybe they just couldn't get through the legal hoops without backing from Nick themselves to pay for those licensing budgets.
Other than the obvious with Timmy, any other series that you guys really want to see get a rep?
While it's not my thing I know Winx Club was popular, and they own it outright to my knowledge, so that could be neat.
El Tigre is a personal favorite for me and I'd love to see him.
Rocket Power is way outdated but I always liked Reggie and Otto's design. Either of them would be cool.
I know Glitch Techs has a sizable fanbase and Miko has a really standout design and potential for a cool moveset even if some of the "gamer culture" stuff kinda makes me cringe.
Kitty Katswell could be fun for a spy moveset, though I know she's kinda the only standout character from TUFF Puppy people care about, for obvious reasons (she's also voiced by an A-list VA so.. if she does get in its probably with an impersonator.)
