Quick Robin, to the bat closet
DC's coming out
If you asked me to list all the characters that batted for the home team I could produce a massive list, however most of it would all be from head cannon. Thats not to say that a few characters have not had their moments. Except Aquaman, I'm pretty sure his preferences go against pretty much every human law ever devised. What are the others into? That is something, my friend, that will be answered.
Now I distinctly remember a few comics here and there through various publishers that have had gay and lesbian characters, the first I personally remember was Rainmaker from Gen-13 . Some claimed that her “orientation was controversial” but to be honest, I never met anyone who actually read comics that cared. It was however still a matter of tongue and cheek comments here and there, and or over the top super-lesbian fantasy fan service to a largely younger male audience.
