Kara Zor-El was born sometime and somewhere on Krypton to Zor-El and Alura In-Ze. When she was old enough, she joined the Kryptonian Explorer Guild to train as a pilot. One time she and her team were in a training exercise for their new mission, to retrieve beacons for the Explorer Guild in a Kryptonian jungle. She sent Nam-Ek and Dora to the south, her and Thara to retrieve one of the beacons, and her boyfriend Kell-Ur and Dev-Em to retrieve one of the beacons.
Dev-Em bitterly questions her authority, but Kara dismissed him and she sent them off. While Kara was locating the beacon, she heard screams from Kell-Ur, who was about to fall off a cliff. She tried to help him up, but she failed and her boyfriend died. She accused Dev-Em for his murder, battled and subdued him, and had him arrested to the Kryptonian Law Council, and Kell-Ur's murder became the first in a thousand years.
She earned her own team and her own ship called Scout Ship 0344, and took off to colonize on a new world. Before they took off, Dev-Em escaped from prison and hid on [mKara's ship, killing her team except for her. When she woke up, she noticed Dev-Em on the ship and her team killed, and the two fought. This caused the ship to land on Ellesmere Island, Canada, on the planet Earth.
She desired to enlist for the Kryptonian Explorer Guild and colonize on a world when she was old enough. When she enlisted, she trained as a pilot with a team and was determined to accomplish her dream. She also cared about her family and her late boyfriend Kell-Ur. She was also brave, able to fight Dev-Em, who killed her boyfriend, and go on a journey far from Krypton.

- Deborah Snyder elaborated on the empty pod in the Scout Ship shown in Man of Steel. "You know what’s interesting, and I don’t know and I’m not going to say what it means or anything, but the one thing if you look closely when Henry’s going through the Fortress of Solitude there’s an empty… you know all the bodies… the pods? There’s an empty pod. I’m not going to say what, or if, it means anything but there is an empty pod there."
- When Zack Snyder was asked directly if the character she was referring to was Supergirl, Snyder responded, “No. [Laughs] I’m not going to say anything but, it’s a thing."
- David S. Goyer went on to say he did intentionally leave some loose ends, not as sequel bait, but just because he thought they were interesting. "There’s a shot there – and, it’s funny, at one point Zack took it out, but I cried ‘Uncle!’, and he put it back in. But you see there are four pods: three of them have skeletons in them, but one is open and there is no skeleton. Zack had missed it the first time he read the script. I pointed it out to him, and he was like, ‘Okay, that’s interesting. That’s an interesting loose end."
- In the DC Universe, Kara Zor-El is Superman's cousin, Supergirl. Kara dreams of flying and saving Kell-Ur from his death as a reference to Supergirl.
