Sontaran

The Sontarans (pronounced "Sohn-TAHR-ans") are a belligerent and militaristic clone race. The Doctor has encountered them at least four times during his travels.

Physical characteristics


A clone race, the Sontarans are humanoids with large, bulbous heads and stocky bodies. They have grey-brown skin and deep set features. They have three digits on each hand (two fingers and a thumb). They are enormously strong and very tough, due to the high gravity on their home planet. Despite this, Sontaran muscles are designed for load bearing rather than leverage, which means they can be easily tied up. One of the few ways to hurt or kill a Sontaran is via a small access port called a "probic vent" at the back of the neck. There are no female Sontarans, since they rely on cloning.

They are typically seen wearing their distinctive battle armor, which resembles a thick grey space suit. Their helmets are round and almost featureless except for two eye holes and a small, flat crest running from the forehead to the back of the neck. They generally carry around a rod-like weapon and a translating device.

Technology


The Sontarans are reasonably advanced, though all their technology was designed for use in the war with the Rutan Host. They use odd, spherical spaceships and can make advanced robots for various purposes. They can use and make a wide variety of hand-held weapons, though they usually use a thin, rod-like energy weapon. This energy weapon is used for energy projection and hypnotism. They can create around a million clones every four minutes, which allows them to sustain massive casualties. The Sontarans have achieved crude time-travel technology which is effective, though not on par with the Time Lords. They have been seen trying to get the Time Lords' more effective time-travel technology.



History
The Sontarans are engaged in a destructive war with the Rutan Host and have been for thousands of years. The Sontarans have reached nearly every galaxy during the course of this war. It's unknown what started this conflict, but this war has driven both cultures. Some of their known exploits have included kidnapping humans for experiments, developing their own TARDIS and invading Gallifrey, but all attempts were stopped by the Doctor.
