The Mutant Phase

The Mutant Phase was the fifteenth monthly Doctor Who audio story produced by Big Finish Productions the third of their "Dalek Empire" semi-linked stories.

It was an early example of a non-original piece of Doctor Who fiction published by Big Finish. It was in fact a remake of an unlicensed audio drama published by Audio Visuals.

This was, according to the fictional timeline, the first performed story to feature an encounter between either the Fifth Doctor or Nyssa and the Daleks.

Publisher's summary Edit

In the 22nd century, the Daleks have occupied planet Earth. By the 43rd century, only a handful of humans survive. Still further into the distant future, a Thal scientist must choose whether to betray his heritage, or see the universe destroyed.

When the Doctor and Nyssa find themselves trapped in this deadly chain of events, they must decide who their real enemies are. What is certain, however, is that no matter where the Doctor turns... his arch enemies, the Daleks, will be waiting for him.

What could possibly be worse than that? The Mutant Phase...
