Dramens

Tall humanoids who put McCoy on trial

A tall, slender humanoid species from the Dramia system who arrested Leonard McCoy for mass murder, blaming his inoculation programme for a plague that had wiped out most of Dramia II nineteen years earlier.

The Dramens appear in the Animated Series episode Albatross. They are much taller than humans, with long limbs and elongated heads, and their justice is known for being swift.
When the Enterprise delivers medical supplies to Dramia, the Dramens produce a warrant for McCoy. Nineteen years earlier he had led a vaccination programme on Dramia II, and soon after he left a plague that changes the colour of its victims' skin killed nearly everyone there. Spock is refused time to investigate, so Kirk takes the ship to Dramia II, shadowed by the security chief Demos.
They find a survivor, Kol-tai, who remembers McCoy as a saviour, but the plague then strikes him and the Enterprise crew; only Spock is immune. The cause proves to be an aurora passing through the system. Spock breaks McCoy out of prison, the doctor finds an antidote, and the Dramens honour him.
