Nicknamed "Dr. Bear" for his physically huge body, Greg Bear Egan (グレッグ・ベア・イーガン Gureggu Bea Īgan?) is an iconoclastic scientist who was also part of the Tresor research team that initially studied Eureka and her relationship with the Nirvash. He was renowned as an 'out-of-the-box' thinker capable of combining various theories into a workable gestalt. He was previously married to Mischa of Gekkostate, and tends to act as if they were still lovers — for instance, he calls her "My little cub" and "kuma-chan", the latter meaning "bear". His behaviour often prompts Mischa to take an even sterner tone than usual with him. He is fond of candy, often has a stash of it somewhere on his person, and once told Renton that the candy was part of an important memory in his relationship with Mischa.
Possessing many insights on the Scub Coral, the Coralians, LFOs, and Eureka, Bear is both stunned and overjoyed to learn that from a scientific viewpoint they were found to be almost identical to the Vodarac teachings of Norb; the similarities were revealed in a taped meeting aboard the Gekko. The underground video of this, along with the information published in Ray=Out became one of the main factors for many people, including some military leaders, to reject what Dewey's group was doing. His name references the science fiction writers Greg Bear and Greg Egan.
