TARDIS Index Files

TARDIS Index Files was a YouTube series that showcased Doctor Who aliens and villains, explaining their histories and what they're capable of.

They are presented by the TARDIS scanner in the Twelfth Doctor's control room. Like Mr Smith's data updates and the Monster Files, they were presented from an in-universe perspective with no references to the "real world" outside of the "Subscribe" end screen.

The Index Files were a monthly feature on the official Doctor Who YouTube channel, and feature illustrations from Rachael Stott.
