Brain spawn

Home Planet: Unknown (probably no planet, as they came into being before the first planets formed)

General
The Brain Spawn are a race of big, flying brains who travel from planet to planet and destroy all sentient thought, which they hate, eventually eliminating the planet in question. They came into being milliseconds after the Medium-Sized Bang. They have been at war with the Nibblonians ever since. The Brain Spawn's ultimate goal is to gather all the knowledge in the universe. This ultimately leads to the construction of The Infosphere. The Brain Spawn cannot see, they only can detect the Delta Brain Waves of a sentient being. Their chief combat ability is to send out a stupefication field that eradicates all intelligence within the blast radius, presumably the field attacks the Delta Brain Wave itself. This makes Philip J. Fry the ultimate champion against the Brain Spawn, as he lacks the Delta Brain Wave and therefore can neither be seen nor fought by them. The Brain Spawn hate conscious thought for several reasons, among which is the fact that thought by others than themselves hurts them. This is one of their few weaknesses.

The Brain Spawn have three apparent classes:
 * Small Brains: Foot soldiers of a sort, not very intelligent, but have huge numbers. Capable of stupefying an entire planet in a matter of hours.
 * Big Brains: A sort of "General", more intelligent, capable of speech, and can trap beings in fictional worlds created from books.
 * Huge Brain: Only one ever seen, capable of firing a beam that can instantly kill large dinosaurs.
