The older sister of the Girl of Steel, Alex Danvers may not have powers herself, but she remains one of the most badass characters in the Arrowverse. She’s helped tackle Earth’s deadliest alien threats as a member of the Department of Extranormal Operations, including a stint as its director, but now helps protect National City as the vigilante known as Sentinel. Though she’s certainly comfortable in a fist fight, a regular occurrence in her line of work, she wasn’t always comfortable in her own skin before coming out as a lesbian. But she’s now living her best life as an out gay woman, and even after heartbreakingly ending her engagement to Maggie Sawyer, she’s been able to find love again through her person, Kelly Olsen. Together with her sister, girlfriend and the rest of the Super Friends, Alex will stop at nothing to keep her friends, family and city safe from whatever threats still to come.
