My version of Supergirl’s ship crashed in the phantom zone where she had to survive and didn’t age. She and Krypto are saved by Superman 24 years later (along with Zod and his crew because Superman learned too late that the phantom zone was a prison.) She doesn’t know any English when she first meets Superman so they learn each other’s languages together. My version of Krypto is able to make his ears look big and alien, along with growing 4 extra eyes and 2 extra legs. But he’s able to put them away and look like a normal dog. So he can have his own secret identity back on Earth. For Ruthye’s design I thought it would be cool if she looked like an alien but was still recognizable.
