This papercraft is John Stewart, a superhero in DC Comics' Green Lantern comic books, the paper model created by wackywelsh, the original template by Xavier. John Stewart is an architect and veteran U.S. Marine from Detroit, Michigan, who was selected by the Guardians as Hal Jordan’s backup after Guy Gardner was seriously injured in a disaster. Although Jordan objected after seeing that Stewart had a belligerent attitude to authority figures, the Guardians stood by their selection, and chided Jordan for his supposed bigoted outlook on the issue. Jordan explained that he just felt that even though Stewart might have the integrity for the task, he "obviously would have a chip on his shoulder bigger than the rock of Gibraltar."
In the early 1970s, John Stewart, an architect from Detroit MI, was selected by the Guardians to replace a comatose Guy Gardner as the backup Green Lantern for Jordan. When Jordan resigned from the Corps for an extended period of time, Stewart served as the regular Lantern for that period. Since then, Stewart was in and out of action due to various circumstances, even becoming the first mortal Guardian of the Universe. He also joined and led the Darkstars when the Green Lantern Corps were destroyed by Parallax. After that, he took over being Green Lantern for Kyle Rayner when he left Earth, also taking his place in the JLA. Now he has begun serving with Jordan as one of his sector's two designated regular-duty Lanterns, designated as Green Lantern 2814.3.
To Jordan, Stewart’s first mission began badly with the assignment of protecting a racist politician and Stewart took advantage of averting an accident to embarrass him in the process. However, Stewart soon proved his worth when an assassin shot at the politician, but Stewart refused to intervene with Jordan to move in response to the attack. Stewart had good reasons for this apparent dereliction of duty when he stopped a gunman from killing a police officer in the outside parking lot at the event while Jordan was pursuing a decoy. When Jordan confronted Stewart about his actions, Stewart explained that the politician had staged it for political advantage. With that adventure, Jordan concluded that Stewart was an excellent recruit after all.
For some time, Stewart occasionally filled in for him as Green Lantern when Jordan was unavailable, including some missions of the Justice League.
After Jordan gave up being Green Lantern in the 1980s, the Guardians selected Stewart for full time duty. Stewart filled that role for some years, during which time he married Katma Tui, the Green Lantern of the planet Korugar who was initially assigned to train John in the use of his ring. Kat and John served together within the Green Lantern Corps of Earth alongside Hal Jordan, Arisia, Kilowog, Salaak, and other alien Green Lanterns.
After John’s ring was rendered powerless through the schemes of Sinestro, and Katma Tui was murdered at the hands of the insane Star Sapphire, Stewart’s life began to unravel. First, he was falsely accused of killing Carol Ferris, Star Sapphire’s alter ego, and then falsely accused of theft by South Nambia. Jailed and tortured in South Nambia for weeks, John freed himself with his old ring, now re-powered thanks to the efforts of Hal Jordan. As a result, John inadvertently freed both a serial killer and a terrorist. When Jordan confronted John over his actions, the two friends came to blows until John realized the “revolutionaries” he had been aiding intended to murder innocent civilians. [Source: wiki]
