J'onn J'onzz (Earth-51022015)

On the scientifically advanced civilization of mars, life was idyllic till the mentally unstable Ma'alefa'ak (Earth-51022015) released a virus that killed his entire people except for himself, his philosophical twin brother J'onn, and their niece M'gann M'orzz (Earth-51022015) were left. Angry at his brother's actions, J'onn took the infant M'gann with him to the one place Ma'alefa'ak went to: Earth. After landing on the earth, J'onn and M'gann were found by farmers Jonathan Kent (Earth-51022015) and Martha Kent (Earth-51022015). Living with the couple, posing as humans, they eventually moved to Metropolis, where J'onn debuted as a new superhero: The Superman.
