The Greatest Sci Fi Villains

In great fiction, you have a protagonist, the good guy, but you also need and antagonist, the bad guy. Many ties, the antagonist is the total opposite of the good guy. A good villain has the same intensity as the good guy. the villain is a key point of science fiction. Here is a list of my favorite villains in Sci Fi.

Gary Mitchell, Gary Lockwood, "Original Star Trek"
Mitchell was Kirk's right hand man and old friend. It was unthinkable for him to turn bad. After being struck by an energy barrier, he began to get super human powers. He was getting more and more powerful by the minute. A big theme in the original Star Trek is that absolute power corrupts absolutely. Kirk was forced to kill his old friend.

Commander Tomalak, Anderas Katsulas, "Star Trek: The Next Generation"
The Romulan Commander who always showed up when you least wanted him to. He is arrogant and always plotting something. In his first appearance, one of his shuttles strayed into Federation space and he demanded it back. In another episode, the Enterprise strayed into Romulan space and he was in charge of the situation.

Gul Dukat, Marc Alaimo, "Deep Space Nine"
This character went through quite an evolution throughout the series. He even worked with the crew and at times appeared to be becoming good. At the end he was revealed to be, the arch nemesis of Sisco and emissary of the anti prophets.

Borg Queen, Alise Krige and Susanna Thompson, "Voyager"
First introduced in "Star Trek: First Contact" she made frequent appearances on Voyager. The queen played a major role in "Voyager's" finale and was a major obstacle in the crew getting home.

Silik, John Fleck, "Enterprise"
Silik was indebted to his patron from the future and was fully devoted to the temporal cold war. He'd help Archer only if he had clearance to do so. He did help the crew learn of the Xhindi and helped Archer save earth from the alien, Voth.

Chang, Christoper Plummer, "Star Trek VI"
Many times when famous actors are cast in familiar sci fi series, it does not work. This was not the case here. Chang was a Klingon war hero who frequently quoted Shakespeare. He was arrogant and overconfident. He even quoted Shakespeare right before his ship was destroyed.

Shinzon, Tom Hardy, "Nemesis"
A clone of Picard, originally intended to replace Picard to provide vital intelligence to the Romulans. The project was scrapped and he was banished to the Reman mines. He is now full of hate. He intended to destroy earth. Picard had to use all of his skills to defeat him.

Emporor Palpatine, Ian McDiarmid, "Star Wars"
At first, he appeared to be a mild mannered Senator with no political ambition. He took advantage of several situations and maneuvered himself into power. He played both sides during the civil war and betrayed both sides. In the end he forgot that what goes around comes around and Vadir turned on him.

President Morgan William Clark, Gary McGurk, "Babylon 5"
Rarely seen on the show, his presence was felt. He looked like any ordinary member of Congress, not sinister at all. He had his predecessor assisted. When the truth came out he declared marshal law and set up a secret police. When he was about to lose power, he committed suicide and tried to take earth with him.

The Cigarette Smoking Man, William B. Davis, "X-Files"
The mysterious man who played a key role in the government's cooperation with the aliens, he obstructed Molder and Skully at every turn. At times he would help them. He played a pivotal role in the final episode.
