History
In 1970, Cory was recruited for NASA's Apollo program to test a top secret experimental ship. In 1972, he went to the moon with his daughter Ella's drawing in his suit. He then went to NASA top secret Base on the darkside of the moon. There, he piloted the Apollo X on what was supposed to be a quick round trip, but he then disappeared and was possibly presumed dead by NASA and his family.
However, the Apollo X's Holdover capsule then had him land on Hinrichs V. Sometime after the landing, Cory's DNA was rewritten, changing him to a creature native to the planet. For 291 years, he survived as a creature.
In 2261 of the Alternate reality, Cory was discovered by Captain James T. Kirk and a landing party from the USS Enterprise. At first(TOS - Lost Apollo comics: "Part 1", "Part 2"
