Once banned from the world of mainstream comic books by the infamous Comics Code Authority, LGBT characters now have a stronger presence in the world of superhero comics than ever before, with gay and lesbian heroes like Batwoman, Northstar and Green Lantern Alan Scott openly declaring who they are — and even getting married. Today, DC Comics told Wired that it will continue to expand the LGBT diversity of its superhero universe by introducing the first openly transgender character in a mainstream superhero comic.
In Batgirl #19, on sale today in both print and digital formats, the character Alysia Yeoh will reveal that she is a transwoman in a conversation with her roommate, Barbara Gordon (aka Batgirl). Taking care to distinguish Yeoh’s sexual orientation from her gender identity, Batgirl writer Gail Simone noted that the character is also bisexual.
