Cyber-Leader (Prologue: The Fourth 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 led a group of Cybermen on a mission to convert the Fourth Doctor, eventually trapping the Doctor inside a mansion with a cyber-converted K9. (COMIC: Prologue: The Fourth 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. (COMIC: Supremacy of the Cybermen)

Behind the scenes

 * The Cyber-Leader and its subordinates were modelled on the "Cybercommander" re-design originally created for TV: The Dark Dimension, the unproduced television story for Doctor Who's 30th anniversary.
