Cyber-Leader (Prologue: The Fifth Doctor)

In an alternate timeline where the Cybermen used Time Lord resources to conquer all of time and space, (COMIC: Supremacy of the Cybermen) a Cyber-Leader served on Skaro after the Cybermen conquered the planet and erased the Daleks from existence. When the Fifth Doctor's TARDIS forcefully landed on Skaro after being dragged through a time corridor, the Cyber-Leader ordered a CyberIsomorph to kill the Doctor. (COMIC: Prologue: The Fifth Doctor) This Cyber-Leader was erased from history when, on Gallifrey at the end of the universe, the Twelfth Doctor and Rassilon used the Eye of Harmony to regenerate the universe and restore the original timeline.
