NON: Non was imprisoned with his wife in the Phantom Zone when Krypton was destroyed, and he, his wife (Astra), and an army of other aliens managed to escape the Phantom Zone when Kara Zor-El's pod first crashes into Earth. Astra leads them with the intention of saving Earth from humanity, but for years they are hunted by the American government's DEO, while Kara Zor-El, known as Kara Danvers on Earth, grows up. Once Kara takes on the mantle of Supergirl, she aids her adoptive sister Alex Danvers, DEO agent, in hunting the Phantom Zone escapees. Non pressures Astra to proceed with her plan to "save" the Earth, despite her knowing that she must kill her niece Kara to succeed. After Astra is killed at the hands of Alex Danvers, Non takes command of the remaining Kryptonians and sets out to do her bidding.
