Jerbyn D. Diamond

Diamond and his sister.

Australian anthropologist, model and fitness expert who has tried to use science to explain some of the superhuman feats attributed to Tarvu. He was the first to suggest that Tarvu had developed gills as a child to enable him to survive for long periods underwater, and, controversially, that he may have somehow absorbed genetic material from Oobu or a member of his family.

This latter suggestion was interpreted by some conservative Tarvuists as an insinuation that Tarvu had had an affair with Ippi, Oobu's daughter.
