Who Was the First Openly Gay Superhero?

The answer depends on whether we count implied or confirmed representation. Extraño (Gregorio de la Vega) is widely recognized as the first openly gay superhero in mainstream comics, debuting in Millennium #2 (1987) published by DC Comics — he was explicitly written as gay, a notable first for a major publisher. Marvel's Northstar (Jean-Paul Beaubier) had been heavily implied to be gay since his debut in X-Men #120 (1979), but his sexuality wasn't explicitly confirmed in print until Alpha Flight #106 (1992), where he also became the first superhero to openly declare 'I am gay.' Northstar later made headlines again in Astonishing X-Men #51 (2012) when he married his partner Kyle, the first same-sex superhero wedding in mainstream comics.
