Izlyr

Izlyr was the Ice Warrior delegate to Peladon when it applied for membership in the Galactic Federation. The Third Doctor initially suspected him and his servant Ssorg of being behind the attacks on Peladon. Izlyr was unhappy about this. However, since the Doctor had saved his life, he felt that he should pay off that dept by helping him. Izlyr helped the Doctor defeat Hepesh and Arcturus, the real culprits. He soon found out that the Doctor and Joe were not really earth delegates at all when he was greeted by the real earth delegate. When he went to find the Doctor however, he seen him go into the TARDIS and Dematerialise. (DW: The Curse of Peladon)
