Azaxyr

Azaxyr was an Ice Lord of Mars and leader of the Federation troops sent to Peladon. He was secretly a member of a breakaway faction which desired to return to the Ice Warriors' former ways of military conquest. He worked for Galaxy 5 and, with Eckersley's help, tried to take over the trisilicate mines of Peladon. He was defeated by the Doctor and killed by Sskel's sonic weapon while fighting Gebek.
