The Gizmobuster Gremlin is one of the many gremlins in Gremlins 2: The New Batch.
He is first seen at a bar where most of the Gremlins where when humans evacuated Clamp Skyscraper and the Brain Gremlin was giving a TV interview, where the Gremlins were watching him on the TVs.
He wears a T-shirt with a logo similar to the Ghostbusters logo with Gizmo in place of the ghost. He was with a gremlin who was reading the book Dinner After Midnight in New York, where the Gizmobuster shirt Gremlin was holding a very light-brown colored teddy bear and both gremlins were laughing about it. He presumably dies along with all the other gremlins when they get electrocuted by the Electric Gremlin.
