Kara Zor-El (Arrowverse Earth-38)

Kara Zor-El is Supergirl, the cousin of Superman. She fights crime and alien threats in her hometown National City in conjunction with the DEO. At the age of 13, Kara was sent to Earth to look after her cousin Kal-El. This did not go according to plan as after Krypton's explosion, shockwaves knocked the pod off-course and into the Phantom Zone. She arrived at Earth 24 years later, when Kal-El had grown up to become Superman. She then realised that she didn't have the mission anymore as her cousin had already grown up, so her cousin brought her to Eliza Danvers and Jeremiah Danvers, who adopted her as their daughter.
