From the files of U.N.I.T.:
This month we look at THE RUTANS: Green, blob-like aliens, engaged in an endless space war with the Sontarans. Rutans like the cold, have a natural affinity for electricity, and are able to shift their shapes.
A Rutan scout became stranded on the Island of Fang Rock, and after killing most of the lighthouse crew and some shipwreck survivors, planned to use Earth as a strategic point in the war with the Sontarans. The Forth Doctor and Leela were finally able to destroy the Rutan with a rocket launcher. The Doctor blew up its mother ship by using diamonds, and converting the lighthouse into a crude laser cannon.
