Potato Cannon

''' is an unique tool utilized by Ryūken Jr. during his battle against Comato and Ume. He also comically remarked it to be the strongest weapon in the Universe.

Design and Properties
Potato canon is a pipe-based cannon combustion of a flammable gas (aerosol, propane, etc.), to launch projectiles at high speeds. It is built to fire chunks of potato at the enemy rapidly. The projectile can be dangerous and result in life-threatening injuries, including cranial fractures, if a person is hit. The force of impact was seen to be strong enough to shatter rib cages and human skulls. By using, a low density gas (helium), it is able to break the sound barrier and finally achieve a super-sonic speed. It can fire around 10 potatoes before it needs to be reloaded again.
