Kyle Rayner is a top member of the Green Lantern Corps from Earth. After the rest of the Corps was destroyed, he alone was selected to bear the last power ring and carry on the title. Although he acted alone for many years, when the Corps was reformed, his skill level gave him a position as an Honor Guard, only behind Salakk and the Guardians in the chain of command of the Corps. He has also been a host for the Ion entity, and a member of the Justice League.
