The Cybermen have been a regular feature for Doctor Who since their debut in "The Tenth Planet" all the way back in 1966. Their first appearence coincided with another major milestone for the show -- the Doctor's first-ever regeneration from William Hartnell into Patrick Troughton.
Back in those days regeneration was called "renewal," and, moreover, the Cybermen were very, very different. For all the upgrades they've gotten over the years, the Cybermen never looked more different than they did in "The Tenth Planet."
Yes, as Peter Capaldi's 12th Doctor prepares for a little regeneration of his very own, the original Cybermen from the planet Mondas are set to return after a 51-year absence in the episode "World Enough and Time."
What makes these Cybermen different? Are they weaker, stronger, faster, slower? What are their likes and dislikes? How can you make a Cyberman of Mondas swipe right?
These are the important questions, really.
And so, without further ado, here is everything you need to know about the original Cybermen.
