I'm just here to dump some TG info here regarding WayForward's latest game, Double Dragon Neon. Picture 96 (of 97) in the Concept Art section has a genderswapped version of Billy named "Lilly". Of course, you have to beat the game to unlock this option and, sadly, I don't have any way to upload that image.
If anyone wishes to do so, by all means, have at it.
