Gary Mitchell

 Gary Mitchell is one of the first major antagonists of the Star Trek franchise, appearing in the second pilot episode of the original series. He served as First Officer of the Starship Enterprise, NCC-1701, during its five-year mission under the command of Mitchell's old friend, Captain James T. Kirk. Their friendship was deep, and their command was alaready shaping up to be a legendary one. An encounter with an energy barrier near the edge of the galaxy nearly wrecked the ship and began to evolve two of its crewmembers, Mitchell and Doctor Elizabeth Dehner, though Mitchell's mutations were the more obvious,extreme and immediate.

Mitchell began to exhibit psionic powers and abilities, and rapidly grew distant towards other Humans, even his old friend James Kirk. He began talking with an odd echo and exhibited glowing silver eyes, and described himself as having ascended to godhood. With Mitchell's power growing geometrically along with the threat he posed, Kirk at last took the advice of Science Officer Spock and Physicist Sulu and made plans to maroon Mitchell on a distant, little-used fueling station where the ship could also conduct repairs. Though Mitchell was fully aware of this scheme, the crew still managed to get him off the ship. All the while, Doctor Dehner, not yet awakened in her power, protested the plan to ditch and maroon Mitchell.

Once at the refueling station on Delta Vega IV, Mitchell began to move against his captors, killing several and leaving Kirk alone to face both him and the now-awakened Dehner. The two planned to remake the galaxy and the wider universe to suit their whims and beliefs. In what would become a series trope, Kirk convinced Dehner that, far from evolving and leaving the worst of Human behavior behind, the two were carrying it with them into their supposed godhood, and this surely meant they must one day turn on each other. He also pointed out how Mitchell already lacked compassion, something a god must always possess. Dehner fought Mitchell, lowering his power enough for Kirk to bury him under a mountain of rock, but died herself in the process. While making a full report, Kirk honored their memories by declaring the pair missing instead of deceased.
