Doctor Who

Doctor Who is a British Sc-Fi Television show that started broadcasting in 1963, it follows the adventures of the "The Doctor" - a Time-Lord from the planet Gallifrey who is able to travel though time in her machine "The Tardis".

Since the shows initial broadcast, it has become a significant part of British popular culture and celebrated its 50th Anniversary in 2013 with the special episode "The Day of the Doctor" written by then show runner Steven Moffat. 

The show will celebrate its 60th Anniversary in 2023 with Russel T Davies set to return as Showrunner.

Thirteen Actors have headed the role on screen since William Hartnell's initial incarnation, the current incarnation is played by Jodie Whittaker who is set to depart in October 2022 and will be replaced by Ncuti Gatwa.

The plot device used to explain the change between actors is officially known as "Regeneration" which allows a critically injured incarnation to renew themselves, it was initially created to allow William Hartnell to step down due to failing health and be replaced by Patrick Troughton and was known as "Renewal", the now official term "Regeneration" was first introduced during Jon Pertwee's Final Serial "Planet of Spiders".

The "Regeneration Cycle" was first introduced in Tom Baker's Serial "The Deadly Assassin" where it was revealed that Time Lords could regenerate 12 times for a total of 13 incarnations, further more details were revealed in Peter Davison's "The Five Doctors" where it was revealed that a Time Lord could been granted multiple cycles allowing further regeneration's - something that was finally used in the Doctor's Case in "The Time of the Doctor".

Incarnations of the Master:

Unlike the Doctor, when the Master first appears he is already on his final regeneration having "wasted" his regeneration cycle. In "The Keeper of Traken" he takes over Tremas body to escape death. By the time of "The Five Doctors" he is offered a new regeneration cycle by "Borusa" on the condition that he saves the Doctor from the Death Zone however they are never received as "Borusa" is revealed to be the villain of the story. 

In the TV Movie, the Master is executed by the Daleks and requests the Doctor returns his remains to Gallifrey, however he is able to escape and like Tremas takes over another persons body - this time Bruce. 

When the Doctor finally catches up with the Master, he is living as Professor Yana, a human scientist tasked with taking the last of Humanity to "Utopia", he finally discovers who he really is and regenerates and takes on the fake identity of Harold Saxon. In "The Sound of Drums" the Master reveals that he was resurrected by the Time Lords and given a new Regeneration Cycle to fight in the "Time War".
