Limbo Lantern

During Blackest Night in this universe, Sinestro had joined as one of the New Guardians who fought against Nekron and had received the power of a White Lantern. Instead of sharing the power he had been given, he decided to keep the power for himself. Unable to control the ring's power by himself, Sinestro and the New Guardians failed to stop Nekron from killing the Life Entity. Nekron killed the remaining Lantern leaders and resurrected them, forcing them to join the Black Lantern Corps. Deciding that he could not live with his actions he tries to commit suicide, however, his body was fused with the powers of both a White and Black Lantern, making him the Limbo Lantern.
