America Guerra (Earth-8920)

"Some of us try hard to make the world a better place than it was when we found it. I know that's what I try to do. I won't always be successful. But that's life. I'm Supergirl. This is my life. I'm pretty happy with it. For now at least."

America Guerra, born as Aleta Boltagon, is the daughter of scientist Mander, the brother of Rynda and the uncle of Blackagar Boltagon. When Titanos was slowly being destroyed, Mander had to ensure his daughter would survive, sending her with a cryogenic pod to a safe haven to the same place her cousin was. Colliding with a asteroid, Aleta crash landed on Mexican, Earth for years until Blackagar, now going by the name of Superman, found and saved her. Inspired by him, America took the name of Supergirl and started to protect Metropolis as a vigilante alongside Superman, other superheroes, and alone.
