Subomar was a humanoid male, a teacher on Nukolee. He was Prince Raviki's earliest teacher, and was almost like a father to him.

In 2267, Subomar greeted Raviki and his escorts, James T. Kirk, Spock and Leonard McCoy, when they arrived at Nukolee in the Galileo. Just before they were to start for the palace, Subomar suddenly pulled out a gun and threated to kill Raviki, but was himself shot by the guards. Raviki was greatly upset that someone so close to him would make an attempt on his life. It was later determined that Subomar had been affected by gases from Sanduy's Comet, which triggered random bouts of temporary madness. (TOS comic: "A World Gone Mad")
