Description
Highly advanced civilization, apparently humanoid, of unknown origin, possessing great powers.  The Metrons intervened in a conflict between the original Enterprise and a Gorn ship in 2267.  The two ships had been involved in a territorial dispute over planet Cestus III.  Seeking to avoid unnecessary unpleasantness in their space, the Metrons sent Enterprise Captain Kirk and the Gorn ship commander to an artificial planetoid, where they were expected to fight to the death.  Kirk won the fight, but declined to kill his opponent, prompting the Metrons to reevaluate their opinion of humankind.  A Metron representative said they had not expected Kirk to demonstrate the advanced trait of mercy, and said that they were so impressed they might wish to contact the Federation in just a few thousand years (Arena -TOS).
