On the latest episode of The Flash, Barry Allen teamed up with Oliver Queen from Arrow. A lot of really awesome things happened in the episode, but one of the things that may not have been caught by everyone was what happened when Eddie Thawne complains to the police captain for the first time and tries to convince him that "The Flash is a public menace," in Barry's words. Meanwhile, the captain leisurely gets his burger ready to eat. While Eddie complains, the captain, thoroughly unfazed by the complaints, says, "My boyfriend is trying to get us to eat healthy, so work is the only place I can eat what I want." (Note that the captain is a man). So DC has introduced a character into the show, even if he has a small part, who is of the lesbian gay bisexual transgender (LGBT) community! That gave me the idea to list some of the LGBT superheroes because DC is becoming more inclusive than in the past.
For now, we'll just stick with DC Comics.
The newest iteration of Batwoman is open about being a lesbian. Whether it's a publicity stunt, something they've put in because they think it's a curiosity, or DC is trying to make LGBT acceptance more widely spread is unclear. But it's still cool to have her in the comics. She fights crime, maintains a relationship, and has A LOT of skeletons in her past. So in other words, she's got one thing more than Batman (other than the obvious), because he can't seem to maintain a healthy relationship to save his life.
2) Midnighter and Apollo
At one point they were married! Now, in the New 52, they're still both gay. They're still in a relationship. However, they're somewhat more cautious about who finds out. Still though, they're a gay couple. Also, their powers are super cool.
Bunker is a personal favorite of mine. He has Spiderman's quick thinking quips, Green Lantern's kind of powerset, and he's a sassy awesome Mexican besides. A relatively new addition, he joined the Teen Titans. If the Teen Titans had to have a token gay hero, Bunker was totally the right way to accomplish it.
4) Alan Scott
The New 52 brought back the original Green Lantern, Alan Scott. He's out and proud from the first issue, and he proposes to his boyfriend. However, an accident halts their happy plans and gives Alan his powers and a tortured past (isn't that always the way?)
So it appears DC is becoming more inclusive. There are others out there. I know there are more in the DC universe. Thought of one I missed? Tell me in the comments!
