John Stewart was selected to act as alternate Green Lantern of space sector 2814 should Hal Jordan become incapacitated. Idealistic, John championed the oppressed, eventually given full status in the Green Lantern Corps by the Guardians of the Universe. Sadly, John's career would be rife with tragedy, including the death of his wife Katma Tui at the hands of Star Sapphire, and the destruction of the planet Xanshi, a result of John's overconfidence.

As part of his self imposed penance John accepted the commission to unite alien cities stolen by a mad Guardian, which became Oa's "Mosaic." After the Corps disbanded, John began a tenure as leader of the Darkstars galactic peacekeeping force until he was crippled while defending the planet Rann. In a final act of friendship, Hal Jordan visited John and healed his injuries before sacrificing himself to heal Earth's sun. For a while, John worked at Shining Light Architecture, and advised Kyle as best he can.

Stewart recently retook his mantle as a member of the Green Lantern Corps after Kyle left him a note by Kyle which asked him to "Mind the Store" in his absence. Later in GL: Rebirth, after being cleansed of Parallax's influence by Ganthet, John helped defeat Parallax with the help of the other GLs. He is currently galavanting around various sectors of space, although mostly sector 2814, wherever the Guardians say he is needed.
