Rutan

The Rutan Host are a race of amorphous green blobs.



Physical characteristics
The Rutans (singular Rutan) are shaped somewhat like jellyfish, with a green, glowing body and many light-green tendrils. These tendrils have surprising strength and they can climb sheer walls or overpower Humans with them. Rutan host can control and absorb electricity, which they can then use for defense and attack. A Rutan can kill a Human with their bio-electricity. Rutans can see, despite having no true eyes, but their vision is limited and monochromatic. They can also speak Human languages.

Rutan host are amphibious and native to a cold planet (Ruta III). They have trouble dealing with climates unlike the ones on Ruta III, such as in warm environments. (DW: Horror of Fang Rock)

Technology
The Rutan Host have unknown types of technology, though they are apparently less advanced then the Sontarans. Rutan spaceships are crystalline in structure and have the appearance of glowing balls of fire. These ships can control the weather to a degree. Individual Rutans can also shapeshift into other forms, but they need to know this form very well, usually after careful study and dissection. This skill was discovered and implemented in the early 1900s. (DW: Horror of Fang Rock)

History
The Rutan Host is engaged in a destructive war with the Sontarans and has been millions of years (though they had brief alliance during the Millenium War). (DW: The Quantum Archangel) All their actions have been to advance the war, such as scouting out new planets to use as bases. Though they originally controlled most of the Mutter's Spiral, by the 1900s, they were starting to lose the war and were forced to retreat to more fortified locations. (DW: Horror of Fang Rock)
