Martian Manhunter

J'onn J'onzz is a green-skinned extraterrestrial humanoid from the planet Mars, who worked as a detective in Apex City under the persona of "John Jones". He is a charter member of the Justice League of America.

Background Information
In the parallel universe, known as Earth-One, the year is 1955 and Dr. Erdel is working on a communication device, with the hope of making contact with extraterrestrial life. Upon its first use, he realizes that he had inadvertently created a teleportation beam. Amazingly, this device pulls J'onn J'onzz to Earth in his martian form. The shock of the encounter kills Dr. Erdel and leaves J'onn with no method of returning home.

While on Earth, J'onn J'onzz decides use his powers to fit in, adopting a human-like appearance and calling himself "John Jones". He joins the police force, and becomes a detective in Apex City. In this role he is secretly able to use his alien powers to help the inhabitants of his new planet. All the while, he hopes that Martian technology will advance to a stage that will enable his rescue.

In late 1956, J'onn J'onzz is able to briefly make contact with his home planet Mars and his parents.

J'onn eventually reveals his existence to the world, by openly fighting crime in a green-skinned form.

By 1964, he wanted to become a 'full-time' member of the newly formed Justice League. In order to do this, he knew that he had to free himself up from his secret persona, detective John Jones. So he allows his secret persona to be killed in action by the Idol Head of Diabolu, an artifact which generates supernatural monsters. For the next few years he will be in battle against the Idol Head. Shortly after its defeat he takes the persona of Marco Xavier in order to infiltrate the international crime cartel known as VULTURE.
