The Abandoned Son Of Krypton (Male Reader X Supergirl)

What happens when the Last Daughter of Krypton finds out she isn't the last of her kind as a pod containing her cousin is caught by the justice league, but a second more unstable pod contains her future enemy or ally and its threatening to destroy the justice league that she worked so hard to build.

But this isn't her story but rather yours, so what will you do Y/N will you leave krypton in the past or take off earth as the new krypton. You certainly have the power to do so, for you are her doomsday made manifest.
