Create your own weapon and describe it.
Simple as the title presumes.
Create your own weapon. Describe it. Is it a metal cannon? a laser? a proton gun? a pistol? a club? a sword? an axe? a shield? an entire spaceship that is formidable enough that everybody assumes that it has the probability of being able to destroy entire planets with its mega ion-electric cannon that generates an energy ball that explodes with great force and burns up Earth and destroys you, me, and all of us, and I describe it as the Coli 😎
