Zhukov (Cold War)

Zhukov was the captain of a Soviet submarine that stuck under the north pole in 1983. He and Proffessor Grisenko discovered the legendary Ice Warrior Skaldak in the North Pole. As Skaldak started rampaging around the submarine, the Eleventh Doctor and Clara Oswald arrived, TARDIS materialising right in front of Zhukov and the astonished and suspicious crew members, before disappearing again because the Doctor had switched on the HADS. The Doctor helped stabalise the submarine and Zhukov thanked him but shortly afterwards he threatened to have both the Doctor and Clara shot. It was then that Skaldak arrived but was electrocuted and chained up by the crew.

Skaldak escaped from his armour and moved around the submarine, picking off Zhukov's crew one by one. The Captain found the Ice Warrior threatening to kill Proffessor Grisenko and tried to shoot him but the Doctor pursuaded him to try negotiating instead. Zhukov agreed but still aimed his gun at Skaldak who congratulated him on his tactical advantage, before adding that he wasn't as at much of an advantage as he'd hoped. The Ice Warrior's armour came stomping through the submarine and Skaldak went back inside it, making him immune to the crews weapons as he prepared to detonate the submarine's nuclear missiles. Clara managed to talk him out if it, reminding him of the loss of his daughter. Then the submarine was pulled to the surface by an Ice Warrior ship, to Skaldak's delight. The Ice Warrior teleported off the ship and left the submarine undamaged in the North Pole. The Doctor then asked Zhukov if he could give him and Clara a lift to the South Pole, since the TARDIS had ended up there. (TV: Cold War)

Personality
A man dedicated to his duty, Zhukov cared about his crew but still believed that a mission must be completed, even if it cost people their lives. He would not hesitate to tell people the exact severity of a situation, telling his crew that their air was running out and that they would most likely all die. He was suspicious of the Doctor and Clara after they appeared from a blue box which had literally materialised out of thin air but decided not to harm them since he felt that he and his crew owed the Doctor their lives after he stopped their submarine from crashing.

Although he was a Captain, Zhukov realised that he was out of his depth in the situation with Skaldak and thus followed the Doctor's lead, although he still threatened to shoot the Ice Warrior when he found him. The Doctor talked him out of it, but Zhukov asserted that he would allow negotiation but only if it was from "a position of strength". Skaldak congratulated him on his tactic and Zhukov acknowledged his praise with a curt "thank you", even as he had his gun pointed at him.

After being rescued by the Ice Warrior's Zhukov lost his serious attitude and let out a laugh of relief, having believed that rescue was unlikely.
