A brilliant scientist whose creation of a time machine allowed him to indulge his passion for women; he kidnapped them from many different times all over the world and held them prisoner in his house. His ship was stolen and his house destroyed by the Silver Ghost; the ship is now in Shamballa for safekeeping. After his plans for building a second time machine were again foiled by the Silver Ghost, Davidon was insane for a time. When he recovered, he helped Taylor Forest in her efforts to overthrow Needles Duncan, by supporting her with his own blood. He went through an agonzing cure to purge the vampiric influence from his body, and now serves both the Silver Ghost and one of his former victims, Hei Lian.
