beta (muv-luv)

"Beings of the Extra Terrestrial origin which is Adversary of human race".

Primary antagonists in Muv-Luv. An alien race that was first spotted on Mars in 1958, arrived on the moon in 1967, and arrived on Earth in the Uighur region of China in 1973 killing 36 million in a week and reducing the Earth's population to 1 billion in 20 years. They consist of distinct classes each with little to no physiological similarities and very little is known about them as all attempts to communicate with or understand them were largely failures.
