Sam was a male Human Starfleet crewmember in the 23rd century. He served aboard the USS Enterprise in 2266 under the command of Captain James T. Kirk, during an historic five-year mission that the starship undertook.
In that year, Sam and Kirk demonstrated some basic self-defense and throwing techniques in the ship's gymnasium for Charlie Evans, a young man whom the Enterprise was transporting to Earth Colony V. He became frustrated with his inability to master the same techniques. When Sam began laughing at him, he was sent to "oblivion" by Evans utilizing incredible psychokinetic abilities granted to him by the Thasians.
Background information Edit
In the script and episode, the character was named "Sam". The final draft script also characterized him as an officer.
In the novelization "Charlie's Law" by James Blish (released by Bantam Books), he was referred to as "Sam Ellis", an officer, who was part of McCoy's medical staff. Of note, a seemingly out-of-place lexicon entry for a "Mr. Ellis" also appeared in the Concordance; however, the corresponding text referred rather to Tom Nellis.
The Errand of Vengeance novels name this character "Sam Fuller".
