Superhero week. Day 6.

UFO, Martians, aliens.. Do they really exist?

Decades ago, J'onn J'onzz was teleported to Earth from Mars and stranded here. Since then he has used his extraordinary abilities to protect and serve the people of Earth.

Centuries ago on the planet Ma'aleca'andra, the Green Martians known as M'yrnn and Sha'sheen gave birth to twin sons. The bearing of twins was uncommon among the Martian culture, and as such, the first of the twins was named J'onn J'onzz, whose name means "Light to the Light." 

In his secret identity, to blend into humanity, he is a gritty hard-boiled police officer.

"I am Mars' sole survivor. There is a reason for that."
