Note: This article contains spoilers for Doctor Who season 12 episode 10.
Surprisingly, The Doctor Who season 12 finale has just confirmed a 44-year-old fan theory.
In the 10th episode, it was revealed that the Doctor isn’t a time lord. Instead, she is the mysterious Timeless Child whose origins remain anonymous.
Additionally, it was revealed that The Doctor is the only living being capable of regenerating, and the Time Lords only picked up the experience as an outcome of joining her DNA with theirs.
Later on, Jodie Whittaker’s Doctor found out that there was many Jodie Whittaker’s Doctor of herself that she wasn’t aware of, stretching way before the supposed first Doctor William Hartnell.
Most of the fans were unhappy with this reveal, and many suggested that it has ruined almost five decades of Doctor Who lore, and this plotline may be mentioned in the 1976 episode ‘The Brain of Morbius.’ In the event, Tom Baker’s Doctor comes up against a Time Lord criminal called Morbius, with both of them being hooked up to a machine that enables them to have a real battle of wits. The Doctor saw all of his previous incarnations,
but it didn’t stop there as viewers were shown eight more unfamiliar faces.
At the time, viewers suspected that these other individuals must have been previous incarnations of Morbius. Still, the producers did confirm that these were pre-Hartnell versions of The Doctor.
Producer Philip Hinchcliffe, author of the 1996 book Doctor Who: A History of the Universe revealed:
“It is true to say that I attempted to imply that William Hartnell was not the first Doctor.N We tried to get famous actors for the faces of the Doctor, but because no one would volunteer, we had to use backroom boys.”
Doctor Who airs on BBC One in the UK and BBC America in the US.
