During The Blackest Night, the Black Lantern Corps attacked Oa and attempted to claim the Green Lantern Central Power Battery. In order to combat this enemy, the Green Lanterns decided to release the Red Lantern Corpsmen Vice from the Sciencells and he immediately attacked the Black Lanterns. However, Alpha Lantern Chaselon's programming activated and he killed Vice whereupon the Black Lanterns attacked Chaselon. Killing him, his Alpha Lantern Power Battery fell and entered into an overload stage. Kyle Rayner managed to grab onto the battery and used it to create a shield around the Central Power Battery which exploded thus destroying the Black Lanterns. However, the explosion claimed his life and he died from the heroic act after saving Oa.
