One of the Corps most distinguished fallen Lanterns, Arkkis Chummuck’s career with the Green Lantern Corps began when he killed the previous Lantern of his sector in personal combat.

Arkkis Chummuck was a scientist who aided his people in invading the forces of Xanshi. Using a yellow armor, he defeated Reever, the Green Lantern of Xanshi unintentionally killing him. As per his peoples custom, ate his remains.

Arkkis was chosen by the ring to join the Green Lantern Corps. He returned to his homeworld of Toomey IV where he used his new powers to force his people from further conquest, ending the war with Xanshi. However his actions did not go unnoticed by the Corps chief prosecutor who prosecuted Arkkis under the charge that he had used his ring to conquor Toomey IV.

Arkkis was instantly put on trial. At the trial, Arkkis was defended by Reever's brother who stated that the Green Lantern acted nobly to end the war. Arkkis was acquitted and Malet Dasim was charged by the Guardians to act as his supervisor while Arkkis learned the ways of the Corps.

Arkkis was a good friend to Hal Jordan and Katma Tui among other Lanterns. When the villiam Malador tried to usurp the power of the central battery, Arkkis battled him until both villain and hero were vaporized in a blinding explosion of energy.
