Despero debuts in chapter fifteen of Year Two, having been attacked by the Sinestro Corps in space and thrown down to Earth, landing in Chicago where his impact sends him through several dozens stories of a building. His fall is stopped by Sinestro, who is 'outraged' by his attack on Earth. Despero is tackled out of the building and into the sky above, and the alien tyrant expresses his fury over Sinestro's games and for his Corps for attacking him. Sinestro suddenly tells Despero to stop, confusing him, and Sinestro then uses his ring to take control of Despero's hands and force him to strangle Sinestro, all the while the warlord 'pleads' with him to stand down.

Despero demands Sinestro release his hands when Sinestro summons an orb construct around Despero's head and neck. Just as Green Lanterns Hal Jordan and John Stewart arrive, Sienstro snaps Despero's neck, killing him. Sinestro had been using Despero to further gain Hal and John's trust, and afterwards discards his body onto a nearby rooftop.
