Mister Glasses
From Multiversal Omnipedia
Mr. Glasses was a mutated gremlin who drank a brain-enhancing serum. His greater intelligence made him the effective leader of the gremlins in Clamp Center. Mr. Glasses nearly led a gremlin invasion of New York City, before Billy Peltzer had them drenched in water and used the Electro-Gremlin to incinerate them all.
