The Doctor is IN

Ok so while my favorite Si Fi series is Incarnations of Immortality, my favorite TV show is Dr Who, specifically with the Tenth Doctor, David Tennant (went as him for Halloween last year). Some background information on the Doctor is that he is a Timelord and the last of his kind. He never ages and travels through time and space and whenever he is about to die, he can regenerate and simply take on a new body.
Here is a clip from one of the episodes.



In this clip you will see three forces fighting against each other. There are the humans, the Daleks, the ones that look like pepper and salt shakers, and the Cybermen who are the ones in the metal suits. So the Daleks are the reason that the Doctor is the last of the Timelords. The Daleks are little squid/jellyfish like beings who found out about the Timelords and build suits to help combat them. They were able to wipe out all of the Timelords except for the Doctor and he is in fact the only Timelord to actually kill Daleks through their suits. Now the Cybermen are the Daleks of the human world. An inventor was getting old and dying so devised a way to keep his brain alive and live forever in a metal suit, like a human upgrade. He started forcing people to do this and amassed an army of Cybermen.
In both cases of the Daleks and Cybermen, there is a corruption and perversion of technology, using it as only a means to conquer and EXTERMINATE. In fact, the Daleks have very common goals to the Nazi party. The Daleks travel the universe and will exterminate anything that is deemed lesser than themselves so that only the superior Daleks will remain in existence.
Now for a optional video, I give you, Chameleon Circuit with Exterminate, Regenerate.
