Skaldak

From Tardis Wiki, the free Doctor Who reference

Skaldak was an Ice Warrior who held the rank of Grand Marshall.

He remained frozen in ice at the Earth's North Pole for approximately 5000 years, before being found by a Soviet scientist, Professor Grisenko, in 1983.

Impatient enough to wait until returning to Moscow, he was thawed by a crew member of the submarine Grisenko was serving aboard. (TV: Cold War)
