Morphius Dumbassius

A creature that can transform their body into any shape or form they want but they are limited by their minds and physical capabilities as in their base forms they are the size of a straw but they can miraculously create machines of mass destruction on a whim, one example of their machines of mass destruction is the "Fun" which can shoot cartoonishly large bombs by pulling a trigger next to the barrel of it

Person 1: Fuck, Morphius Dumbassius spotted near town
Person 2: yeah, we're definitely screwed
