A United States Air Force colonel who interrogates Captain Kirk in 1969 after catching him breaking into a base to remove evidence of the Enterprise.
Colonel Fellini appears in the first-season episode Tomorrow Is Yesterday. The Enterprise has been thrown back to the twentieth century and photographed by Captain John Christopher's interceptor, so Kirk and Sulu beam into the air base at Omaha to take the film and tapes. Kirk is caught.
Fellini questions him with rising exasperation. His prisoner has a strange uniform, odd equipment and no papers, and answers everything with a joke. When the colonel threatens to lock him away for two hundred years, Kirk reflects that this would be about right.
Spock, Sulu and Christopher arrive to free the captain, and Fellini and his guards are overpowered. Once the ship returns through time, none of it has happened. He was played by Ed Peck.
