The Brain Gremlin is a character from the movie "Gremlins 2: The New Batch". He was a normal Gremlin until he drank brain hormone, which caused him to become more intelligent than the rest of the Gremlins. Murray Futterman hosed him with water, and Billy and Kate set the Electric Gremlin loose. The Electric Gremlin electrocuted the Brain Gremlin, causing the Brain Gremlin to fry and melt, killing him.
