Which character do you want to come out of the closet
for me seeing Thor falling in love with Silver Surfer would be epic, Thor holding Surfer's waist while Surfer screaming "I'm the king of the world" on the surf board, with the large throbbing asgardian penis rubbing his silver shiny butt. traveling the cosmic together.
or Superman finally embrace the love with Batman, Superman gets divorced, leave Jon and Lois, Batman gives up his secret identity. kills the Joker (who is madly in love with Batman). That way Superman and Batman can live in a secluded mountain area as Clark Kent and Bruce Wayne, they can take turn being on top.
