Organian

The Organians are a one-episode super race who intervened when the Federation and Klingon Empire both sought control of their homeworld, Organia. They appear only in the TOS episode "Errand of Mercy".

Attributes

The Organians appeared to be human, but they were eventually revealed to be beings of pure energy. The extent of their powers is unclear, but they were able to prevent the crews of both Federation and Klingon warships from operating their consoles, thereby preventing a battle between two fleets.

Organization

The Organians appear to be loosely organized, having a single leader to speak for them. How this spokesperson is chosen is unknown.

Threat Assessment

The Metrons appear to possess great power which is presumably inherent to their energy-based physiology. They could presumably overcome any of the major powers in the Alpha Quadrant if they chose to do so, but they have no apparent interest in conquest. As staunch pacifists, they are not even dangerous to invaders, although they might use their powers to disarm antagonists if sufficiently motivated.
