Living Flesh Supercomputer

The Living Flesh Supercomputer was a nefarious entity which Box suspected was at work by 2019 at the school attended by Tasha Williams' young cousin. (PROSE: Out of the Box)

Behind the scenes
The school-controlling Living Flesh Supercomputer originates in Class, a horror webseries created by Stuart Hardy, spanning twelve instalments between 2016 and 2020. It was used in Out of the Box with Hardy's permission. Although not otherwise directly connected to the Doctor Who universe, Class was initially created under the guise of a satire of what the then-recently-announced, but not, as yet, debuted, Doctor Who TV spin-off of the same name might hypothetically look like.
