Supergirl

Kara Zor-El was sent from Krypton to protect her baby cousin, but spent 24 years stuck in the Phantom Zone. By the time she arrived, her cousin was already Superman, and she grew up with the Danvers. Kara saves her sister Alex's plane and becomes Supergirl. She learns Alex works for the DEO, run by Hank Henshaw, who is really J'onn J'onzz, the Martian Manhunter. The enemies come from Fort Rozz, the Kryptonian prison that crashed with her, including her aunt Astra and Astra's husband, Non. Astra dies, and Non activates Myriad. Kara breaks the hold with a message of hope, beats Non and nearly dies flying Fort Rozz into space. In the end, a pod crashes near the city.
