John Stewart

John Stewart was the first black superhero to appear in DC Comics back in 1972.

Stewart – an architect and veteran marine – was chosen as the backup Green Lantern to Hal Jordan, but has since gone on to be a key hero in his own right.

There are rumours that he is set to be the main Green Lantern in the DC Cinematic Universe, with Tyrese Gibson potentially portraying the character.

He has also been a member of the Justice League, the Guardians of the Universe, the Darkstars and the U.S. Marine Corps and he has wielded the power of the Indigo Tribe.

Is Stewart your pick for the greatest Green Lantern?
