Mutant (Revelation of the Daleks)

This Mutant was a product of Davros' experiments on Necros. He attacked the Sixth Doctor before Peri Brown killed him to save the Doctor. Before he died, the mutant forgave Peri and told the Doctor the Great Healer had used him as a genetic experiment. His appearance and hostility were caused by the experiments.
