Jarl

Jarl was a Cyberman from the planet Mondas, and was a member of the second Cybermen force which invaded the Snowcap Base in Antarctica in December 1986 with the intention of detonating a Z-Bomb in its missile silo. Jarl and the other Cybermen were eliminated during the invasion when their home planet and power source, Mondas, disintegrated. (TV: The Tenth Planet)
