Rassbur

From Tardis Wiki, the free Doctor Who reference

Commander Rassbur was the head of an Ice Warrior team sent covertly to Peladon. Having learned a group of mercenaries were going to steal treasure from the planet, Rassbur and his team were sent to observe and stop the theft. They set up in an abandoned refinery beneath the Citadel of Peladon.

They were able to kill most of the mercenaries when they tried to flee after their theft. However, Nic Reece threw a Sontaran fragmentation grenade at them and collapsed the tunnel they were in and escaped. Rassbur and some of the other Ice Warriors managed to survive and return to the Bruk for medical attention. (PROSE: Legacy)
