Barney Juniper has long been tenured in the field of Electromagnetic Acceleration but began to grow tired of the monotony before seeking the challenge of joining in the Doctors' primate liberation efforts. As a senior expert in their field at the Apus Core-99 Township, Barney dropped their post without delay upon learning of the Critical Earth Expedition. With their sights now set on Earth, Barney and the Doctors will do what they can to liberate the primates that remain in captivity there.
