Ssorg

Ssorg was the Ice Warrior sub-delegate, alongside Lord Izlyr, to Peladon when it applied for membership in the Galactic Federation. When Arcturus tried to kill the Third Doctor, Ssorg saved the Doctor's life by destroying the delegate using his sonic gun.

He later reported to Izlyr that their communications equipment had been destroyed by Hepesh. (TV: The Curse of Peladon)
