Killswitch Tane, a veteran activist of the Universal Primate Captivity Crisis movement at Strangelove University of Science and Medicine of Virgo, has been on several primate retrieval operations in the 29 years since earning their Practical Theology Doctorate. Having long lived by the tenets of Doctor society, Killswitch decided to join the cause of the Critical Earth Expedition for the benefit of the primates. Now, as their mission leads them to Earth, Killswitch and the Doctors will attempt to put their skills and education to work as best they can for the sake of the primates there.
