Azaxyr

Ice Lord of Mars and leader of the Federation troops sent to Peladon (planet). 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 Five and, with Eckersley's help, tried to take over the Trisilicate mines of Peladon. He was thwarted by the Third Doctor, and killed by Sskel's sonic weapon while fighting Gebek. (DW: The Monster of Peladon)
