Tigris Teal, an up and coming purveyor of the Hyperspace field, learned of the Universal Primate Captivity Crisis from activists attending Common Quasar Technical School of Leo and joined the expedition to free the captive primates of Earth. Having lived life among the Pioneer caste, Tigris had helped to settle many new colonies in the galactic frontier, but decided to find a new purpose helping others with the Doctors. With their sights now set on Earth, Tigris and the Doctors will do what they can to liberate the primates that remain in captivity there.
