Ndora

Ndora, also called Kibo, was the fifth planet of System C-71. It was uninhabitable by humanoids, having lethally high levels of energy, but was home to a creature called the Energy Dragon.

In 2266, a Bandit asteroid ship being pursued by the USS Enterprise (NCC-1701) launched a missile toward Kibo/Ndora. Believing that it contained evidence to clear James T. Kirk of charges of treason, Spock and Leonard McCoy used cerebots to go to the planet and find the missile. They were attacked by the Energy Dragon, but the Spock cerebot drove it off with a phaser and returned to the Enterprise with the evidence.
