Torchwood: Audio Original 10: Mr Invincible

And that, that was the end of the Torchwood audios, until the release of The Conspiracy several years later. Oh, sure, there was The Exodus Code a few months after, but what promised to be a new start petered out, a single release. This was almost a Doctor Who story in structure, strange phenomena, someone who thinks they're a superhero, a mysterious awkward child. Felt very much like early Torchwood, rather than the darker more serious drama the show became. Still good, as always.

There were the full-cast dramas, and then there were the "audio originals" which were dramatic readings (a short audio book for which no book existed).

The full-casts include Lost Souls, which was commissioned for Cern's LHC activation day, three plays commissioned for radio broadcast (similar to how the Eighth Doctor Adventures were originally made for BBC7) later released in a set with Lost Souls as Torchwood: The Radio Adventures, and another three plays broadcast alongside Miracle Day branded as Torchwood: The Lost Files.

Doctor Who Audio Originals also exist, and have been semi-ongoing since Series 4 (they are currently in the middle of a short serial featuring the Twelfth Doctor and some new companions, set between S9 and S10).
