Chendaki

The Chendaki are a race of bloodthirsty warriors that rely on their intimidating physical appearance to gain an advantage over their enemies. Interestingly, their brain is not located in their head, allowing them to survive if it is removed.

History
The Chendaki are one of the most well respected warrior races in the universe, and their name is known in all corners of the galaxies. They are not necessarily malevolent, but are willing to enter brutal combat to ensure a victory. They are known for their harsh treatment of their criminals, opting to send them to be judged by the Tachyon Judicial Alliance. One such criminal had his head removed and was sent into deep space. He eventually arrived on Earth, and took up the mantle of the Headless Horseman. Following his subsequent disappearance from the planet, two Chendaki soldiers tracked down the Doctor and Jess, who had aided in his rescue, demanding to know what had happened. Briefly, the Chendkai were wiped from existence before the Doctor reversed the process.

Physical Appearance
The physical appearance of the Chendaki is their most valuable possession, particularly when combat is involved. Their skin varies in colour, but they share similar facial traits: large, bulging eyes, scales covering their skin, and a mouth full of razor sharp teeth. Chendaki soldiers wear heavy duty armour to protect themselves from laser blasts.

Powers and Abilities
Apart from their intimidating appearance, the Chendaki do not bear much in the way of natural ability. They have a great deal of brute strength, and their civilisation is notably advanced. They possess an array of weapons, capable of vaporising their enemies.
