A Boltzmann Brain is a type of intelligent being, usually defined as a Cosmic Entity of sorts, formed from mathematical or physical chaos rather than the normal organic processes which generally give rise to life. Although extremely unlikely, random changes in the quantum structure of a universe may give rise to a self-aware entity; this process never occurs in almost all universes, but in the infinitely large higher-level -verses it occurs infinitely often. Therefore, there are an infinite number of Boltzmann Brains in existence.
