Miro

Miro was the commander of the first Thal expedition to Spiridon.

Miro was killed on touchdown when their ship crashed, leaving Taron, the mission doctor, in command. His associates were forced to abandon their ship and deceased commander to carry out their mission on Spiridon. His body was discovered at the ship's controls by Jo Grant some time later.

Miro's remains were disintegrated with the Thal ship when Daleks discovered the wreck and engulfed it in an explosion with their gunsticks. (TV: Planet of the Daleks)
