Thompson accompanied Captain Kirk, Commander Spock, and Doctor McCoy to the surface of Mygdalus III. After the landing party's arrival, Thompson suffered severe head trauma and massive internal injuries. After the attack ended, the Mygdalians were able to completely heal Thompson. Thompson then returned to the Enterprise, still feeling great from his recovery.
Unbeknownst to him and the crew of the Enterprise, Thompson was somehow cloned by the Mygdalians. Thompson and the Enterprise then made contact with one of his clones on a Orion freighter. Dr. McCoy then conformed that the clone is Jason Thompson much to the original's surprise. McCoy then deduced that Thompson was somehow copied in a way. Thompson along with his clone then accompanied Capt Kirk, Commander Spock and Dr. McCoy as they investigated further on Mygdalus III. There they found over 2,472 exact duplicates of Thompson in stasis. (TOS - Burden of Knowledge comics: "Uncertain Prescriptions", "A Matter of Perspective", "The Burden of Knowledge")
