Coloth was a young male Ulk-Ra. He had a brother named Otchon.
Tasked by the chief male of his clan, Coloth underwent a rite to become considered a warrior: he went out into the wild with the goal of killing a beast and bringing back its pelt. However, Coloth was found by Ossu-male, an Ulk-Ra augmented by the War Lords, and captured. Coloth was kept trapped in woven vegetation for a while until - on orders from the War Lord programming - Ossu-male killed Coloth by slicing him open with his paws. (PROSE: War Crimes)
