Stripe

Stripe is the principal antagonist of Joe Dante's Gremlins (1984), a malevolent Mogwai distinguished by the white mohawk-stripe of fur down his head. Spawned from the offspring of the gentle Gizmo after the three rules are broken, Stripe transforms into a lizard-like green Gremlin and leads the destructive horde that overruns the town of Kingston Falls before being destroyed in a department-store fountain (Wikipedia)
