Unhcegila is a Lakota snake demon of unbelievable ferocity and evil. Originally arising from the Atlantic Ocean (where it is believed he was imprisoned), he ravaged tribes in North America as he migrated to the Central US, residing in the sacred Black Hills of South Dakota (Paha Sapa to the Lakota people).
He is described as having eyes of fire and a fanged mouth, with impenetrable natural armor and claws like iron. His gaze is reported to cause instant insanity. Because he is a Class X entity, he is believed to be a GOO servitor or hybrid experiment of a GOO servitor breeding with another native life form. Currently, Unhcegila is imprisoned in the Homestake Paranormal Activities Research Center, a facility dedicated to research and control of Class X Native American Spirits. Uhncegila is an old enemy of Wakan Tanka, the Lakota Great Spirit, and seeks the destruction of her and her prophetess.
Unhcegila is reported to have up to 3 offspring at a time, are also reportedly Class X entities, who ravage tribes in their insatiable hunger and are fearsome opponents in battle.
