Kara Zor-El was 15 when her planet Krypton was destroyed by the World Killers and was sent in one of the last two functioning escape pods along with her baby cousin Kal-El. She was sent to protect her cousin on their new planet Earth, where they were being sent, but her pod was sent off course and she was frozen in time in the Phantom Zone. Decades later, her now adult cousin, who has become the hero Superman, finds her ship in the Phantom Zone and takes her to earth. Clark Kent then takes her to live with friends of the Kent family, the Danvers, and she changes her name to Kara Danvers and starts going to high-school in National City and becomes Suoergirl. But even though she has a new “home” she feels very out of place and like a failure because she was sent to protect her cousin and could not.
