HORROR OF FANG ROCK
Mentioned several times in previous episodes but never seen, the Rutans, fearless and ruthless enemies of the Sontaran Empire, have been engaged in a Fifty-Millennium long war.
Often spoken of as the winning side, in their one and only on screen appearance, I'm not quite sure that anyone imagined that such a victorious race would resemble these green blobs of nonsense, that wobble onto the set looking like massive radioactive Jellyfish...with extra green blobs of nonsense on them.
And yet, their appearance still doesn't prevent them from being incredibly powerful and manipulative.
When referring to themselves, it is always as a group unit, "We"or "us", suggesting that there is some form of hive mind, a link between the Rutans.
Upon murdering an old lighthouse keeper, Ruben, the first to die at Fang Rock, the Rutan then take his form and use it to appear as though nothing is amiss. They do however, resort to killing those who interfere, using the same method of electrocution as they would in their pure form.
Although maintaining the image impressively well, they did admit to the Doctor that they find human form difficult to hold.
