Margot Robbie's Harley Quinn and 17 Other LGBTQ+ Superheroes

Season one of The CW's "Batwoman" features the canonical story of Ruby Rose's Kate Kane getting kicked out of a military academy for being in a relationship with a female cadet. Kane became the first queer iteration of Batwoman in 2006, 50 years after she was introduced as Batman's love interest, per Autostraddle. Rose left the series after the first season and Javicia Leslie's Ryan Wilder took over Batwoman's cowl. Ryan is a lesbian.
