Avery Grus has long been dedicated to their studies in Hueristic Research but has always held an interest in the Universal Primate Captivity Crisis and has now become committed to a missionary in the Doctors' liberation efforts. A dedicated Doctor through and through, Avery has always sought to offer aid not just to the Apskellion, but to the apes of all worlds, including those of Earth. Now, as their mission takes them to Earth, Avery 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.
