Grash

	Sword of Orion
	Bruce Montegue

Grash was a crew member on the Vanguard. He disagreed with Deeva Janson's captaincy, and created a mutiny, because she wouldn't agree for Grash to execute the Doctor and Charlotte Pollard. His mutiny eventually failed, when he fell under the control of the Cybermen, but they killed him when he went insane. (AUDIO: Sword of Orion)
