As an expert in the field of Mathematics, Simulacra Kaufman has long been a prominent name amongst the ranks of the Doctors, and now uses that influence to help steer the focus of their primate liberation efforts. A child of the Zealot caste of Apskellion Space Apes, Simulacra was left behind in a conflict with the Doctors and was taken into their care and raised as one of their own, but waits for the day that they can break free and return to their own people. Now, as their mission takes them to Earth, Simulacra and the Doctors seek to confront the Homo Insipiens for their failure to free their captive primates as they had promised to do so long ago.
