As an expert in the field of Industrial Technology, Bronto Armitage 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. Bronto was originally content to be stationed at the Cardioc Terminal performing duties to benefit the Doctors, but upon learning of the Critical Earth Expedition they decided to step away and pursue the path of activism. Now, as their mission leads them to Earth, Bronto and the Doctors are dedicated to the liberation of the primates in captivity there.
