This is the start of your new life, Brian; a life without worry or pain or loneliness, a life filled instead with colors and music and euphoria, a life of light and pleasure.
~ Aylmer influencing Brian to use his liquid.

Aylmer is the main antagonist of the 1988 comedy horror film Brain Damage. He is an alien parasite that manipulates his host by drugging them with his brain juice.

He was voiced by the late John Zacherle.


Aylmer is an ancient parasitic alien revered throughout history from the liquid he secretes, which drugs the human brain. His diet consists of brain matter from living organisms. While fed animal brains throughout his life, Aylmer grows tired of it and escapes. He comes across the apartment of Brian, and manipulates him into feeding him brains in exchange for the liquid drug.
