Arretan androids were humanoid androids which were created in 2268 to hold the minds of Sargon, his wife Thalassa, and their friend Henoch, who were the lone survivors of their race.

They had placed their minds in spheres, becoming beings of pure energy. The android bodies would have given them mobility and allow them to leave their planet. They borrowed Human bodies to build the androids.

The plan failed when Henoch, enamored with the return of physical sensation, tried to destroy Sargon and keep possession of his host, Spock. Although Henoch's plan was foiled, Sargon and Thalassa ultimately did not use the android bodies, as they decided they did not have the discipline to use their mental powers in the physical realm.

By 2401, an Arretan android body was kept in storage among Section 31's high-security artifacts at Daystrom Station. (PIC: "The Bounty")

The Arretan android was portrayed by William Blackburn.
