Doctor Who fans left reeling by series 12 finale’s huge twists
The episode included some shocking revelations about the Doctor's true identity **SPOILERS FOR SERIES 12 FINALE**

Published:
Doctor Who wrapped up its 12th series last night on BBC One and it’s quite possible that some fans got a little more than they bargained for.
The climactic finale tore up the lore that had comprised Doctor Who canon for the last 50-odd years, once again calling into question the lead character’s true identity.
The biggest reveal was that the Doctor herself is not actually from Gallifrey after all, but a mysterious being of unknown origin.
The ability to regenerate is something that was once unique to her, but the Time Lords spliced their genetics with her to gain this handy skill themselves.
All these revelations allowed for the addition of several other Doctors to the show’s official canon, including those briefly glimpsed in the fan favourite story The Brain of Morbius.
Needless to say, the episode got fans talking…
Chris Chibnall just made everything canon. Fan films. Big Finish. Thasmin fanfics. Everything. #DoctorWho

Twitter user @sisterhood_karn was thrilled that the “Who” of the show’s title made sense again after years of big reveals regarding the Doctor’s identity.
We have no idea who the Doctor is or where they come from. The title makes sense again! #DoctorWho?

Meanwhile, @shes_biochem pointed out that this was far from the first time that Doctor Who has changed its own mythology…
People are like “CHIBNALL SHOULDN’T MESS WITH 50+ YEARS OF CANON!!! HOW DARE HE!!! ” Like Russell T Davies didn’t kill off the timelord race and Moffat squeeze a whole ass doctor between 8 and 9. Weak argument, get over it #DoctorWho

The Cybermen made their return in the finale, this time more threatening than ever before as they too gained the ability to regenerate thanks to some tinkering by The Master.

The episode left things on a major cliffhanger, as the Master was left (possibly) dead and the Doctor was incarcerated by the Judoon on an asteroid prison in the far reaches of space.

Generally, fan reaction seems to have been positive, but inevitably when such sweeping changes are made, some viewers aren’t going to be too pleased.
Everyone who hated Moffat now wishing for his return now #doctorwho pic.twitter.com/Z6lbqcSl0v
