Marius Bellus, a veteran activist of the Universal Primate Captivity Crisis movement at Dwingeloo Research Group of Corona Borealis, has been on several primate retrieval operations in the 23 years since earning their Quantitative Biosciences Doctorate. Marius has long struggled to put their Doctorate to fulfilling use, having been relegated to menial duties at the Kong Township, but soon discovered the much more appealing missionary work of the Critical Earth Expedition. With their sights now set on Earth, Marius and the Doctors will do what they can to liberate the primates that remain in captivity there.
