General Cooper serves as a military authority figure in a leadership role overseeing defense and security operations against anomalous threats. He maintains direct interaction with the Federation for Extraterrestrial Research (F.E.R. Labs), an organization dedicated to studying extraterrestrial phenomena. Cooper exhibits skepticism toward the Ultra Force's methods during monster encounters, aligning with F.E.R. Labs' institutional stance questioning the necessity of lethal force against the Sorkin Monsters. His operational priorities emphasize conventional military protocols over the Ultra Force's direct interventionist strategies.

General Cooper's narrative function centers on representing institutional military authority and its inherent tensions with unorthodox defense entities like the Ultra Force. His involvement is strictly confined to the original narrative's initial conflict featuring King Maera, with no appearances in subsequent seasons, movies, OVAs, or spin-offs.
