I have - sort of. A lot of it is one party racebent instead of their canonical races. Mostly not canonical pairings, though, but that's typical for all types of fanart. I think people fanart who they most like and/or who they think will get responses. Have seen a little Ororo Munroe stuff. Definitely CassSteph, though I do not ship it. But yeah, way more trio stuff, Tim/Steph, Dick/Babs, Bat/Cat and Ted/Booster. Well, Fire/Ice, but she's seemingly got quite a bit of European ancestry, given how she's depicted in comics. There's probably Connor/Kyle stuff, but I don't ship that, either, so never looked, and he's whitewashed a bit in some comics (fanart doesn't make that mistake and will even sometimes make him darker than he was in any comic canon). And, of course, he doesn't exist in the comics anymore. To what degree the WW pairings are canonical is nebulous. And many fanarts are of exes, too, because comics won't let characters stay together.But I NEVER SEE INTERRACIAL despite DC and Marvel has/had canon interracial romance.
