The Gremlins are the titular antagonists of the popular movie franchise of the same name "Gremlins", based very loosely on the mythological creatures said to vex aircraft these monsters were notable for being mischievous and chaotic, obsessed with destruction and cruel practical jokes. They are largely-unknown reptilian goblin-like creatures. The Gremlins also had a primitive social-structure with more cunning/vicious members gaining higher rank via bullying or outright murder - the most powerful of the Gremlins in the original film was the cunning but deadly "Stripe".
