A Human named Charles Evans, the only survivor of a crash landing on the planet Thasus, was granted considerable psionic powers so that he might survive.

After Charlie misused his powers and caused considerable trouble for the crew of the Enterprise, the Thasian appeared as a translucent, floating Human face.
