Mars was once divided between green and white Martians, but they achieved peace after J'onn J'onzz, a Manhunter officer and the best among them, represented Mars in a peace treaty along side Protex, the representative of the white Martians. J'onn has a wife named M'yri'ah and a daughter named K'hym. He also has a twin brother, Ma'alefa'ak, who has a strong hatred for Martians because he lacks the telepathic abilities innate to their kind. While on a mission, J'onn learns of a deadly virus on Mars spreading through telepathic communication. He returns home, just to witnesses his family die. In that moment, J'onn is unintentionally teleported by Dr. Saul Erdel to Earth in Middleton, Colorado on the year 1963. J'onn establishes a psychic link with Erdel, who dies shortly afterward due to old age. Stranded on Earth, J'onn learns about humanity and is inspired by Martin Luther King's speech, he takes on the appearance of a black man, the identity of John Jones and becomes a detective, befriending detective Diane Meade, who discovers his secret but decides to help him. In the 80s, John gets approached by another Martian, M'gann M'orzz, who reveals Ma'alefa'ak spread the virus. J'onn confronted his brother with M'gann's help, defeating him and adopting M'gann as his niece. They stayed together until the present day. As heroes emerged, J'onn disguised himself and went around the country observing the others waiting for when to intervene.
