other alien races, is recruited as his replacement in the Corps. Katma Tui eventually grows into one of the most respected Green Lanterns, but she and the rest of Korugar initially resists her appointment to the Corps. Due to Sinestro's actions, Korugar has come to consider the symbol of the Green Lantern Corps an emblem of terror and oppression. Punishment and villainy For using the power of the Green Lantern to instill fear rather than combat it, the Guardians banish Sinestro to the antimatter universe, a counterpart to the "real" universe made up of "negative matter". Sinestro ends up on the antimatter world of Qward, that universe's counterpart of the Guardians' homeworld Oa, which is ruled by the Weaponers of Qward, a race of warriors and scientists that bare a fierce hatred of the Guardians and all Green Lanterns.

After releasing Hal from the bubble to eliminate him, Sinestro is defeated and imprisoned in a green bubble by Hal, who does not take him back to his universe as it would go against the jurisdiction of the Guardians. Using a ring that can drain the Green Lantern's ring-power, Sinestro
