5 Classic Doctor Who Scenes The Timeless Children Fundamentally Changed
5. Brain Of Morbius
Possibly the influence on this entire new era of Doctor Who, 'The Brain Of Morbius' features a sequence where Morbius and The Fourth Doctor are involved in a mental battle. During this scene, we see the previous incarnations of The Doctor, followed by eight other faces that are heavily implied to also be The Doctor.
This scene was shown again in The Timeless Children, during the montage where The Doctor uses her memories (enhanced by those she can access in the Matrix) to break out of her paralysis and entrapment within the Matrix of Knowledge itself.
Now we know these to be literal past faces of The Doctor, as Hartnell was never the first incarnation of the character, merely the first she remembers. But, that raises another question; if the other incarnations have been removed from The Doctor's mind, then how does Morbius access them?
Worth mentioning is that Morbius is one of the Time Lord's worst criminals, who may well have accessed knowledge beyond regular Time Lords. Also worth mentioning is that the Sisterhood of Karn were on Gallifrey before the species developed time travel. There is every chance that either of these entities had access to knowledge beyond that of The Doctor.
