Zappo

Zappo is a monster that likes to run around, point his plastic handgun at passerbys in the street and yell, "Zap! Zap!"
In truth, Zappo would like to have a real death ray weapon.
One that would vaporize and maim with great efficiency.
Fortunately, those weapons only exist in the secret stashes of the army who are sensible and use them very responsibly.
