Guardians of the Universe

The Guardians of the Universe are supporting characters in the Green Lantern series. While normally used for heroic purposes, due to the Guardians abandoning emotions long ago they often mishandled the solutions of dealing with a situation on what is best to resolve it. In addition there have been a few guardians that have gone rouge such as Scar and Krona. Prior to the New 52 relaunch, despite their faults, the guardians were usually there to deal with the situation. Following the relaunch, they have begun to head towards a more villainous role due to their unemotional nature.

New 52
After brainwashing Ganthet to whom they previously banished before due to him possessing emotions, Ganthet as a result of this procedure and his previous experience as a member of the Green Lantern Corps began bringing up the flaws in their group, just like the case of the Manhunters and the Guardians now believe that the time has come to revive the First Lantern and working on creating the third army that will replace the Green Lantern Corps.

Among the goals of their agenda, besides wiping out their own Lantern Corps, they also intend to wipe out the other Lantern Corps as well as they deeply resent them, and have also taken action against them as well.
