Ivan Petrov
From Tardis Wiki, the free Doctor Who reference
Ivan Petrov was a Russian soldier from the Crimean War, who had been abducted by the War Lords, who failed to hypnotise him into participating in their simulated version of the war. He fought against them as a member of the resistance. He, like all the surviving victims of the War Lords, was returned home by the Time Lords. (TV: The War Games)
