Dr. Arnada was a doctor, a friend of Lydia Duane and Arthur Morwood-Smyth. When the pair found an amnesiac Elisa Maza walking a road on Easter Island, they took her to their hotel room. Then, they asked for Arnada to give her a checkup and find out why she'd lost her memory.
Arnada determined that some trauma must have caused her mind to blank out her past, and recommended they take her to see his brother in Honolulu, a neurologist, and more qualified to treat her condition. However, they were stopped by Goliath, who took Elisa back. The three tried to stop the gargoyle, thinking Maza endangered, but Goliath literally shrugged them off.
Arnada, Duane, and Morwood-Smyth trailed Elisa's "abductor," but instead found Nokkar. They allied themselves with the alien, becoming his new human friends. What happened to Dr. Arnada is as yet unknown.
Dr. Arnada was a good doctor, but otherwise seemed to be a normal human male of average athletic ability.
