Brain Gremlin is a major antagonist in the 1990 American comedy-horror film Gremlins 2: The New Batch.

After uncovering a science lab at Clamp Enterprises, one of the gremlins drank an intelligence potion, giving it the ability to speak fluent English in a British accent and a (slightly) more civilized demeanor.


Brain Gremlin can be distinguished from other gremlins by his expressive orange eyes, glasses, brown skin, wooden pipe, blue shirt, and gray tweed jacket.
