Badass Gay

Western Animation

 * OK K.O.! Let's Be Heroes has Enid, a badass bisexual witch, Red Action, a lesbian from a future fighting team, Lord Boxman, the pansexual evil leader of Boxmore, and Professor Venomous, the bisexual former hero Laserblast.
 * Steven Universe:
 * Gems don't have sex as humans understand it, but they do have fusion, which is treated similarly in some ways. Fusion between gems of the same stype is "normal", and just produces a larger gem of the same type. Fusion between different types of gems (which produces a new type of gem, distinct from the components) is treated as unusual/inappropriate/perverse. The pairings below are "gay" both in the human sense (all gems are, or at least appear, female) and in the gem sense (because they're heterofusions).
 * Pearl is an expert fencer and tactician, helps defend the Earth from alien attacks on a constant basis, and had feelings for Rose Quartz that were romantic. Also a discount lesbian, given that she's a female-presenting alien.
 * Garnet is a weird example, since she's a stable fusion of two Gems who are deeply in love with each other, meaning that she's literally the physical embodiment of a discount lesbian romance and is very badass.
