Yeti Rhythm has long been tenured in the field of Cybernetics but began to grow tired of the monotony before seeking the challenge of joining in the Doctors' primate liberation efforts. Born of the more aggressive Zealot caste of Apskellion Space Apes, Yeti was abandoned in a New Frontier colony and adopted into a family of Doctors, eventually learning to embrace their more empathic ways. With their sights now set on Earth, Yeti and the Doctors will do what they can to liberate the primates that remain in captivity there.
