Sontarans come from a large, dense planet named Sontar in the southern spiral arm of the galaxy which has a very strong gravitational field, which explains their compact stocky form. They also are far stronger than humans. Sontarans are all descended from the genetic stock of General Sontar (or Sontaris), who used newly developed bioengineering techniques to clone millions of duplicates of himself and annihilate the non-clone population. He renamed the race after himself and turned the Sontarans into an expansionist and warlike society set on universal conquest.

Species Name: Sontaran

Type: Humanoid

Physical Traits: Stocky build, greenish brown skin, and a distinctive dome-shaped head. Although physically formidable the Sontarans' weak spot is the "probic vent" at the back of their neck through which they draw nutrition. It is also part of their cloning process. It provides incentive to continue moving forward in battle since retreat would expose this area to their enemies. They have been killed by targeting that location with a knife, a screwdriver, a mallet and an arrow. They are also vulnerable to "coronic acid".

Height: 5-6 ft

Weight: 170 lbs

Mobility: Legs

Sensory Organs: Visual

Communication: Vocal

Reproduction: Sontarans reproduce by means of cloning and thus for the most part are extremely similar in appearance. Sontarans can mass-clone themselves at rates up to a million embryos every four minutes. Thereafter the clones take just ten minutes to grow to adulthood.

INT: 3D6, WIS: 3D6, STR: 4D6, DEX: 3D6, CON: 3D6, CHA: 3D6, MR: 3D6, HPs: CON +D20.

Orbit/Climate: 1 AU. Very stable, circular orbit, very stable surface temperature.

Atmosphere: Standard Oxygen/Nitrogen with significant ozone component in the stratosphere.

Oceans: 30%

Gravity: 100%

Feeding Habits: Ominvore

Lifespan: 70 years

Technology: 9. Sontarans mainly use spherical or semi-spherical single  occupant spacecraft. They also have large motherships on which the small Sontaran spheres are carried. The Sontarans have a variety of weapons. Their trademark weapon is a small rod with two handles and a plunger at one end giving it a syringe style. But this is so it can be held and fired using three fingers. It shows the ability to fire a beam which can disarm by knocking the weapon out of the wielder's hand, hypnotise as well as cutting through wood and killing. They also use Meson Guns , a large silver rifle with a red fuel tank in the centre which is a kind of flame-thrower. Generals also carry batons which can fire an orange beam that can stun a target.

Culture: A malevolent, truly malicious race with no redeeming qualities at all. Sontaran society revolves around the Sontaran Empire and have an extremely militaristic culture; every aspect of their society is geared toward warfare and every experience is viewed in terms of its martial relevance. Sontarans have detached, smug personalities, and a highly developed sense of honour. All Sontarans have monosyllabic names, many beginning with an initial 'st' sound. Subdivisions of the Sontaran military structure include the Sontaran G3 Military Assessment Survey and the Grand Strategic Council, the Ninth Sontaran Battle Group, the Fifth Army Space Fleet of the Sontaran Army Space Corps, and the Tenth Sontaran Battle Fleet. Military titles include Commander, Group Marshal, Field Major, and General.

Government: Military Dictatorship

Population: Unknown due to horrendous casualties in their ongoing war with the Rutan Host race but considered in the millions.
