Cyber-Leader (Revenge of the Cybermen)
From Tardis Wiki, the free Doctor Who reference
A Cyber-Leader was in command of an ancient Cybership which attempted to destroy the planet of gold, Voga, to stop the production of glitterguns. After planting bombs in the core of Voga failed, he planned to ram the Nerva Beacon in to Voga.
It was killed when the ship was destroyed by the Vogan rocket Skystriker. (TV: Revenge of the Cybermen)
This Cyber-Leader was among the foes whom the Fourth Doctor saw call out to him in his mind shortly before his fall from the Pharos Project radio telescope, which resulted in his regeneration to his next incarnation. (TV: Logopolis)
