Mutt

Mutt is a member of the Sontaran race whose severed head has been repurposed for Solon's grotesque experiments. Displaying the motor reflexes typical of electrocuted Sontarans, its twitching mandibles and moving eyes prove its survival despite surgical separation from its body. The head serves as a power source and monitor for Solon's contraption, reducing the once-formidable warrior to a twitching component in Karn's dark science. Its presence underscores the episode's themes of dehumanization through technological domination.
