Earth 2 by James Robinson, Nicola Scott, Eduardo Pansica and Tomas Giorello (DC Comics)
When DC Comics announced their status quo changing "52" event, they teased that one of their mainstream heroes would come out as gay. In June 2012, Alan Scott, the original Green Lantern, came out in the pages of Earth 2 which is set in an alternate reality of the DC Universe.
"He doesn't come out in issue two; he is already a gay man," writer James Robinson said in an interview with Rolling Stone. "Alan Scott is super-heroic, he's super gallant, he'll die for the earth, he'll die for its people, he's everything you want in a hero. I imagine he's such a Type A character that when he realized he was gay, he was like, 'Okay, I'm gay, now I'm just gonna go on with my life.' He's so accepting of it himself and he's such a compelling person that the world knows Alan Scott's gay. He's such a leader, he's such a good man, that the Justice League don't care. And that's a healthy depiction of a team and how it should be."
