Kyle Rayner

Kyle Rayner is a fictional comic book superhero appearing in books published by DC Comics, usually in those starring the Green Lantern Corps, an extraterrestrial police force of which Rayner is a member. Created by writer Ron Marz and artist Darryl Banks, Rayner first appeared in Green Lantern vol. 3, #48 (1994), as part of the "Emerald Twilight" storyline, in which DC Comics replaced Green Lantern Hal Jordan with Rayner, who was the sole Green Lantern for years until the late 1990s. During this period he was also briefly known as Ion.

Following Jordan’s return to Green Lantern status in the 2004–2005 limited series Green Lantern: Rebirth, and the 2005 crossover event "Infinite Crisis", Rayner returned to his alias of Ion. After the events of the "Sinestro Corps War", Rayner returned to his original role as a Green Lantern officer, along with a promotion to Honor Guard Illustres of the Corps.
