Bio: Also known as Gangmi, Yeti, Raksa, he is an Earth Elemental built on the remains of a Neanderthal. He fled with survivors of the Cro-Magnon's genocide to the Himalayas, where they became mistaken for "Snowmen" and were eventually wiped out by disease from a Western army.
He promised Matango that he would remain neutral in the conflict between Green and Grey, and has a dormant spot of fungus on the back of his neck in order to keep him so. When he allows Swamp Thing to free the other Earth Elementals, a member of the Grey activates the fungus for takeover.
After the defeat of Matango, the now infected Otehrah becomes the leader of the Grey, but he calls off the war with the Parliament, even though the Grey still want total control of Earth.
