When Hal Jordan renegades and tries to leave, John joins the others in subduing him. However, this is a front: he later helps Hal escape, believing Superman has only good intentions. He goes back to Earth with Hal and discovers him and his Regime facing the Lanterns, with Sinestro and his Corps aiding the Regime. Once the Green Lanterns are taken prisoner John joins the Regime in enforcing peace around the world. Once an entire armada of Green Lanterns come back seven months later, Guy Gardner tries to make peace before things get out of hand. Shocked when Superman coldly rebuffs him by breaking his arm, John tries to stop the war to the best of his ability, though he is stopped by Sinestro. Having realized the Regime is not as well intentioned as he thought, John is killed by Sinestro to make sure Hal at least remains steadfast, with Guy taking the fall for John's death and being killed in turn by Hal. In the comic book continuation of the television series "Smallville," Stewart is a member of the Green Lantern Corps who works as a police detective for the NYPD in his civilian identity. He helps train Clark Kent in the use of his power ring, and later teams up with the hero to defeat Parallax. IGN ranked John Stewart as the 55th greatest comic book hero of all time describing him as one of the first dominant African-American heroes in the pages of DC Comics; IGN also stated that John Stewart has gone from "semi-obscurity in the mainstream to absolute recognition" thanks to his starring role in the acclaimed Justice League cartoons.
