KX Launcher

A KX Launcher is a handheld long distance artillery weapon.

Capabilities
The KX Launcher is used to launch a poisonous bullet, designed by Caesar Clown to kill Big Mom. According to Caesar, one bullet is more than enough, while he prepared three for the alliance's plan.

Although it is deadly, it cannot pierce through Big Mom's extremely tough skin.

Trivia

 * The poison of the weapon is based on real-life VX nerve gas, the deadliest nerve agent known to man.
