Moving on to everyone’s favorite green skinned alien, the Martian Manhunter.
Origin: J’ohn J’onzz being a Martian, lived on Mars with two factions of Martians, the Green and the White. J’ohn is teleported to Earth by a scientist, who dies at the shock of seeing him. J’ohn shifts into a human form to disguise himself and to fight crime while he waits to go back to Mars.
Life: J’ohn later becomes a founding member of the Justice League of America. He also joins the Justice League International. He lives a long life as a hero, until he is killed during the Final Crisis. He is prominently shown as a Black Lantern during Blackest Night, fighting Barry and Hal. At the end of the Blackest Night J’ohn is one of the few to be revived. He plays a key role during Brightest Day, becoming the earth elemental.
Why he’s on the list: While Dick is the heart of the DCU, J’ohn is the heart of the Justice League. His death kicked off the horrible Cry for Justice sadly, but it was believable how hard his death affected Hal and Ollie. J’ohn is one of the strongest characters in DC, with powers on the level of Superman. Brightest Day shows him at his best, using his skills to find the other Martian while still showing his softer side. Also he has an addiction to Oreos, that once deprived of them he went on a rampage.
