HeatherÂ Douglas, AKA Moondragon, is a telepath, martial arts master and geneticist with a somewhat convoluted origin story. When she was a child in Los Angeles, her family came upon Thanos landing his spaceship -- so, like any villain, he blew up her family's car and left her as the lone
survivor; her father's being (or something) was then transferred into Drax the Destroyer. While the MCU might not be able to make her Drax's daughter (or fit that entire backstory into their 'verse), she'd be a great addition considering she's also been an Avenger and a member of the Guardians of the Galaxy, which would help strengthen ties between Marvel Studios' film and TV properties. Moondragon is also openly bisexual. She'd be a much needed badass LGBTQ character added into the MCU and someone that could expand their space-related world on Earth, even if she never makes it into the cosmos, and vice versa.
