The Bat Gremlin is a fictional creature featured in the 1990 film Gremlins 2: The New Batch.
Bat Gremlin began as an ordinary gremlin before it drank from a beaker that contained a bat formula. It caused bat wings to sprout from its back. The Brain Gremlin injects Bat Gremlin with an SPF solution allowing it to fly through a wall and around New York City.
It swooped down and attack Murray Futterman who managed to grab its legs and throw it into wet cement. The Bat Gremlin slowly climbed out of the cement and flew to a perch on a church roof where the cement hardened, encasing the gremlin so that it represented a gargoyle.
