While leading a training exercise in a Kryptonian jungle, she split her team to retrieve three beacons for the Explorer Guild. She sent Nam-Ek and Dora to the south for one, Dev-Em and Kell-Ur, her boyfriend, for another, and partnered with Thara for the third.
Dev-Em bitterly questioned her authority, but Kara dismissed him and 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 couldn't save him. She accused Dev-Em of his murder, battled and subdued him, and had him arrested to the Kryptonian Law Council. Kell-Ur's murder was the first in a thousand years.
Her leadership and valor earned her a team of her own, with a scout mission captaining Scout Ship 0344 to colonize a new world. Kara and her subordinates entered stasis chambers during the journey, intending to sleep for ten years until arriving at their new world, but when Kara awakened, she found that Dev-Em had escaped from prison ten years ago, secretly boarded her ship, and killed the entirety of her crew. The two fought as the ship approached Earth, resulting in a crash landing on Ellesmere Island, Canada.
She followed her lifelong dream and enlisted in the Kryptonian Explorer Guild, trained as a pilot and leader and remained determined to accomplish her goals. She cared about her family, but even knowing she may never see them again, she bravely set out 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.
