Alien Brain

The Alien Brains are a small floating race of alien creatures, named for their shape rather than their intelligence. In fact they are not quite independent thinkers, their programming is initiated in the vat-wombs in which they are grown and later imprinted by their purchaser. The Brain is a bio-weapon that will die for its master if need be. They have no homeworld but are known to be produced on 15 planets.
