Azaxyr

Azaxyr was an Ice Lord of Mars and leader of the Federation troops sent to Peladon. He turned out to be a member of a breakaway group eager to return to return to the Ice Warriors' former militaristic glories. He became an agent of Galaxy 5 and, with Eckersley's help, tried to take over the trisilicate mines of Peladon. He was thwarted by the Doctor and killed by Sskel's sonic weapon while fighting Gebek.
