Skaldak Grand Marshal Skaldak was an Ice Warrior titled the sovereign of the Tharseesian Caste and vanquisher of the Phobos Heresy . According to Eleventh Doctor , Skaldak was " the greatest hero the proud Martian race [ had ] ever produced . " Biography . He commanded a fleet called the Nix - Thassis , with his daughter , Iclar beside him . Despite being an Ice Lord , he wore the armour of a typical soldier due to the amount of protection it gave him . ( PROSE : " The Jeopardy of Solar Proximity " ) The Doctor also claimed that his foes honoured him so much they carved his name into their flesh just before they died . ( TV : " Cold War " ) In a battle against the Dalek s over Knossos , Skaldak held off their attack so that his daughter could escape . His ship was then trapped in the gravitational pull of a star . Deciding to bring the Daleks down with him , Skaldak boarded their ship , and killed many on board . He escaped the ship by using the Daleks ' temporal technology , hoping it would send him somewhere cold . ( PROSE : " The Jeopardy of Solar Proximity " ) He wound up frozen in the ice at the Earth ' s North Pole around 3000 BC . 5 , 000 years later , in 1983 , Soviet scientist Professor Grisenko found him . Impatient enough to not wait until returning to Moscow , Piotr , a crew member of the " Firebird " , thawed Skaldak with a blowtorch . Disorientated from the sudden awakening , Skaldak went on a brief rampage that caused the submarine to begin to sink . After the Doctor saved the " Firebird " by guiding it to an underwater ridge , Skaldak was knocked out and captured , and later learnt how long he been in the ice , which sent him into a state of grief . This was exacerbated when he attempted to contact his fellow Ice Warriors , but they didn ' t respond . Feeling he had nothing left to lose , he left his armour to learn more about the submarine and the humans . As soon as he learned about the nuclear missiles on board , he decided to fire them and wipe out humanity as payback for attacking him . However , just as he was about to fire them , another encounter with the Doctor made him hesitate , and the Doctor ' s companion , Clara Oswald , appealed to the memory of Skaldak ' s daughter to make him stop . Moments later , a spaceship belonging to Skaldak ' s fellow Ice Warriors arrived to rescue him . He left on the spaceship , and deactivated the warheads as a final show of mercy before he left Earth . ( TV : " Cold War " ) Personality . Like most Ice Warriors , Skaldak was honourable but when he was desperate he threw away his honour and started crawling around the submarine out of his armour , something that was considered highly dishonourable among the Ice Warriors . Believing that he was the last of his kind , Skaldak decided that honour didn ' t matter any more and devoted himself to getting revenge instead . He was ferocious in battle , and his reputation was legendary ; it was said that his victims carved his name into their skin before they died . He tore most of his victims to pieces in the submarine in order to learn more about human physiology . However , Skaldak did have a sensitive and sentimental side . He was upset by the death of his daughter and in honour of her memory , he stopped his murderous rampage , after Clara reminded him that if he went through with his plan he would cause other people to go through the same pain he ' d suffered when he lost his family . Skaldak showed his honour and mercy by deactivating the warheads before he left Earth , having originally intended to use them to start another World War . He also showed respect to fellow warriors , even if they were his enemies , and complimented the Captain on his strategy of negotiating " from a position of strength " . ( TV : " Cold War " ) Behind the scenes . Skaldak was the first Ice Warrior to be seen on - screen outside of his armour . However , only his hands , arms and face can be clearly seen , the rest being either blurred or out of shot . Thomas Wolff voiced Shaldak in the German dub of " Doctor Who " .
