Mixodar was a male Humanoid in the 23rd century, a native to the planet Jodarr. He was adjutant to the new Emperor Ledoy.
History
In 2266, Mixodor met a landing party from the USS Enterprise, introduced himself to James T. Kirk, and provided horses for them to ride to Ledoy’s castle. Mixodor rode with Kirk, Spock and Montgomery Scott into the castle and presented them to the emperor. When Ledoy promised to bring the visitors to the Great Vrunon, Mixodar ordered that the imperial barge be prepared to set sail.
Later, Kirk volunteered to fight against a gordoon, a dragon-like animal, in arena combat. As he mounted with his horse with a joust, one of Mixodar’s spies noticed a hidden phaser. As that violated the rules, Mixodar confronted Kirk, who handed him the weapon. (TOS comic: "Spore of the Devil")
