Unless we have a Green Lantern episode, I'm going to rule Sinestro out of the picture. Definitely Kobra, Ocean Master, Queen Bee, Ra's al Ghul and the Brain as they have been mentioned in episodes (minus Ghul, for whom an action figure has been made). I might even say the Joker, seeing as he has appeared in the YJ Comics. Though admitisly I don't know the context of his appearence.
