If You Could Make Your Own Weapon, What Would It Be/Look Like?

Excalibolg

Chainsaw gun that shoots chainsaws and dubstep.

Persuadertron! The brainwashing gun! Make your own personal mob of fanatical brainwashed minions! =D

The Wet-Fart Gun. Whoever gets shot with it will make a loud wet fart that drizzles with brown and stinky fluids coming out of one's rectum. Could be hilarious at conventions.

A guitar that shoots fire and/or flaming shotgun shells from out of the headstock every time the user strums.

The Pencil of Mass Destruction.

A gun that shoots out chainsaws

A gatling gun that shoots boiling hot hotdogs

HL3 Gun, it shoot a copy of HL3 with a Gaben inside.

A gun that removes all the sounds made by the target.

It wouldn't necessarely be a "weapon", but you could do a few fun things with it.

If i'd make a weapon it would be a stick that would break easily.
I'd probably try to sharpen one of the ends, or tie a knife at the edge, which would fall off when used.

I have no weaponcrafting skills.

Vodka Shotgun

A Portal Gun that will release the Kraken out of portal when used.

A jacket that functions as a more advanced HEV Suit which allows me to form a weapon of my choice using nanomachines.

A Disembowel Ray, with settings varying from "Peruvian Death Pepper Chili" to "Atomic Meltdown." Imagine packing this baby in a crowded mall or sporting event, strolling through the opening doors by yourself on Black Friday as everyone else crawls toward the nearest restroom.

I'd take two piston driven guns, remove the recoil springs, and then attach the two bolts with a toggle lock.

When one gun fires the other bolt slams forwards, so you get a magdump that alternates between barrels.

I made myself a gunblade + other swords out of steel

a .50 bolt action sniper rifle with a suppressor and transformed to be used by left handed... or a big pump action shotgun.

grenade of healing

1Gg antimater bomb...

It would look like me, but faceless and powers on par of a Saiyan.

His arms with guns mounted on them

A Crossbow combined with an AA-12 and a grenade launcher on it.

A sleeve gun. These things exist, but they are so badass, a gun in a sleeve! Probably shooting .45 ACP bullets.
