Let’s enjoy the many and various faces of the Doctor, regenerating in sequence! It’s simple, but hypnotic. The YouTube user Dave Clipson has made this Regeneration Cycle morphing from one Doctor to another in order. It draws out is the similarities between the faces.
You may see a seamless(ish) line between William Hartnell and Peter Capaldi in which hawklike noses and sharp eyes appear when you least expect them. After you watch the cycle a few times you’d be forgiven for claiming a distinct family likeness between all twelve Doctors. Never stop watching!
