Kara Zor-El

Kara Zor-El is the last daughter of Krypton, who was sent to Earth alongside her cousin, by her parents, right before Krypton exploded. Kara's pod ended up getting knocked into the phantom zone, where she remained dormant for 32 years, before she crash landed on Earth. She soon became the sidekick to Superman, under the codename Supergirl, later becoming a member of the Titans.

Early life
When Kara was 13, Krypton was on the verge of destruction. In order to save her and her cousin, their parents placed them in pods, sending them to Earth. Kara's pod got knocked off course, however, and ended up in the Phantom Zone, frozen, for 32 years.

She finally crash landed on Earth in the year 2009, where she was rescued by Superman and the Kents. She soon after became Supergirl, and was taken under Superman's wing.

Personality
Kara is a very outgoing and curious teenager, still adjusting to the likes of Earth. She does fear things that caused the destruction of her planet, such as Brainiac, whom she had a mental breakdown over.

She is willing to do what needs to be done, just like her cousin, as shown when she flew into space to stop a missile before it reached the sun.
