Cyberman (Prologue: The Fifth Doctor)
In an alternate timeline where the Cybermen used Time Lord resources to conquer all of time and space, after the Cybermen conquered Skaro and erased the Daleks from existence, (COMIC: Supremacy of the Cybermen) a CyberIsomorph was ordered by a Nomad Cyber-Leader to kill the Fifth Doctor, after he and Peri Brown were forced to land the TARDIS on Skaro. (COMIC: Prologue: The Fifth Doctor) This Cyberman, along with the rest of the timeline, was erased from existence after the Twelfth Doctor and Rassilon, at the end of the universe, used the regenerative energy within the Eye of Harmony on Gallifrey to restore the original timeline.
