The Lab Assistant was a Terachnoid who was on Yerek. He was being bullied by two Thugs that Ratchet killed. The Lab Assistant then gave Ratchet a Grav-Tether and taught him how to use it, despite the fact that he was a "primitive type." He then told Ratchet that Pollyx was last seen at the Azeril Caverns.
