John Stewart was pretty fascinating on that show because he dodged so many tropes usually put on black guys in genre fiction. That was likely due to Ben Tucker and McDuffie being in such influential positions, and Bruce Timm never struck me as tone deaf about stuff like that.
I'd probably bring the Jinx relationship from the toons over into the comics. That would make Cyborg more interesting in the comics, and she is probably Cyborg's best love interest in any medium, in my opinion. Cyborg isn't really an idealized hero, so it actually fits well that his girlfriend would be some weird evil girl. The toons, of course, put a silly spin on the whole thing, but a clever writer could get a lot of mileage out of that.
