Katmos

The Tyrannical leader of the Elementals.

Prehistoric Period
During the Prehistoric era, Katmos was a tyrannical ruler who had conquered the entire Elemental race. He had committed genocide on the Clay Elementals, leaving Sondu as one of the few survivors.

When the world was to be hit by an asteroid, Katmos took 5 others (Kierza, Sondu, Gole, Corito and Heri) into a "Sanctuary Pod" which would survive the catastrophe.

Modern Day
Katmos' pod was discovered by David Kapatelis, who opened it and released the Elementals. Katmos then killed the team on the dig-site.

Katmos and the Elementals came up against The Green Lantern, Sana and The Flash. Katmos left once The Green Lantern and The Flash were under their control.

Katmos had Heri killed when he tried to leave the Elementals.

When Kierza reported that the local Heroes had recruited Sondu and were coming, Katmos decided to return to the Pod and go back into hiding.

When they returned to the pod, the remaining Elementals were destroyed. Katmos was the last to die after The Green Lantern destroyed his pod.

Powers and Abilities
Iron Skin - Due to his physiology, Katmos' skin had all the strength and durability of Iron.
