I saw this fan work done in gaia and so I decided to make my own. This is of the doctor who series with all the actors who played doctor who. Ya see the original doctor who's,William Hartnell, health deteriated to the point where he could no longer play the role so they got patrick Troughton to play the new one,the way they handed him the mantel of the doctor is to have William do one more episode so that he could rengenerate into patrick. So began a tradition of when the actor ether quit,got to sick,or was fired he would be replaced by someone else,so a regeneration would happen and the next actor would take over. I hope you like my doctors!! Also here is who's who and how long they played as the doctor.
