Biography
Nilson, along with Solow, was a convert to the ideology of the East Bloc, the power bloc opposed to the base. After the death of Solow's husband and parents, Nilson convinced her that the philosophy of the East Bloc was the answer to all of life's problems, but for the East Bloc to wipe out all suffering and injustice on Earth, sacrifices would have to be made.

Nilson used Maddox to commit sabotage on the base. After he was discovered by Vorshak, Nilson took Tegan Jovanka hostage. Nilson threatened to kill Tegan, but the Fifth Doctor blinded him with an ultraviolet converter. He stumbled down the corridor and was eventually shot and killed by the Sea Devils.
