Ganatus (The Mutant Phase)

Ganatus was a companion to Professor Ptolem, and a long time friend. He was part of the Thal research group that helped the Daleks into the effects and cause of the Mutant Phase. After the mutant phase invaded Skaro and the Dalek Emperor forced the Doctor to return the the 22nd century, the Emperor implanted his mind into Ganatus' to make sure Ptolem and the Doctor did their work. This caused the paradox that caused the mutant phase in the first place. (BFA: The Mutant Phase)
