The Flasher Gremlin is a gremlin that appears in both Gremlins and Gremlins 2: The New Batch, portrayed by a different gremlin in each of them. Both of them are seen wearing a trenchcoat and a pair of sunglasses, both of them have a penchance to open their coat to flash women. He isn't dangerous like the others, but considered inappropriate. He has an interest of Kate Beringer, as seen in both films. Also in both films, he was holding a cigarette in his mouth, although isn't seen smoking.
In the first film, the Flasher Gremlin appears behind the counter in Dorry's Tavern and flashes and scares Kate Beringer who is forced to serve the gremlins that are running rampant inside the bar. He was seen again at the movie theater where he laughs hysterically at the movie Snow White and the Seven Dwarfs, and sings along. He is one of the gremlins chasing Billy, Kate, and Gizmo as revenge for cutting off the movie. But then he burned and exploded to death by the gasoline explosion.
In the second film, a similar gremlin appears in front of Kate, but this time she gets angry and kicks the gremlin away, sending him flying and screaming "WHHHOOAAAHHH!!!". He was most likely destroyed by the Electric Gremlin.
The Flasher Gremlin has possibly influenced in the movie "Munchies", a parody of Gremlins, where the monster race that parodies the Gremlins called the Munchies have an interest of women.
