Vath Sarn first appeared in DC Comics' Green Lantern Corps: Recharge #1 (November 2005), and was created by writers Geoff Johns and Dave Gibbons, and artist Patrick Gleason. The character is from the planet Rann, initially depicted as a veteran soldier of the Rann-Thanagar War, resulting in some tensions between him and his sector partner Isamot Kol, a soldier from Thanagar who was nevertheless more willing to look past their old conflict than Sarn. However, over time, the two move past their war history and become friends; when Sarn loses his legs during the Black Lantern Corps' assault on Oa, Kol actually has his own legs surgically transplanted onto Sarn, reasoning that his physiology will allow him to re-grow his lost limbs and wanting to give his friend the chance to continue his service in the Corps.
