Arakssor was an Ice Lord who led a group of dissidents on Mars.

Millions of years ago, the Martian civilisation faced strife when Arakssor led like-minded Ice Warriors in an attempt to take over his people's government. His aim was to turn his race from a noble, peaceful species into a conquering one. He was stopped due to the intervention of the Time Lord known as the Doctor and the Martian elder Geldar. Arakssor and his band of war criminals were banished to primitive Earth, where they were imprisoned in the ice of the Antarctica under a sentence of life imprisonment. During a skirmish in the prison, all the individuals within the facility were frozen, including the Doctor and Geldar.

There they remained until the year 2012, when a human expedition led by Lord Barset accidentally woke the Ice Warrior criminals and Arakssor. He quickly took over the facility whilst attempting to track down escaped humans and the Doctor. When his forces had secured the prison, Arakssor freed his opponent Geldar from the ice and murdered him in cold blood. Arakssor planned to take over Earth and become the supreme ruler of the Ice Warriors. He would turn them into the brutal warrior race he had envisaged.

In furtherance of this task, he used a Sonic cannon from the prison to heat the Earth's waters and destroy human civilisation by bringing about a terrible ice age. His later attempts at contacting Mars also failed and he learnt that his people were gone. Mars were now uninhabitable. The Doctor thwarted Arakssor's plans by summoning a Martian warship. It attacked the prison from orbit. The renegades' punishment for escaping imprisonment was death. The facility collapsed and Arakssor was mortally wounded by weapon fire from Genevieve Marceau. The tunnel he was in collapsed. Freezing water claimed the Martian warlord's life. (AUDIO: Frozen Time)
