If you were to create a weapon...

The Chuck Noris Tron 9000

 

A Pistol that uses mini Tesla-Coils to discharge large amounts of electricity in order to shock multiple enemies at once, forming a sort of chain-lightning. I call it the Tesla Pistol.

 

Like this one I found over the Big I-net?

You may or may not be able to buy that irl. It may or may not work.

 

I would think something very colorful, that could be shot like arrows

 

hm.. grandark from grand chase much?

 

Wow. This thread is getting quite a lot of replies... I LOVE IT!

 

Schrödinger's Gun.
A gun which simultaneously kills and does not kill your enemies.:alien:

And Occam's Razor in addition

 

Catana - sword in the shape of a cat

 

Ahem... Schrödinger's Catana, I presume?

 

The Trojan Rainbow, It's a giant wooden rainbow which has two rabbits and then when it's open they turn into a million tiny rabbits that cause immense amounts of fluffy destruction.

 

I like how you think. A blade that kills most likely in a simple manner?

 

Yeah, just like that

 

now that i think about it, i always wanted to dual-wield scythes

 

I don't think scythes are one-handed!

 

It may be a kama

 

well, these are!

 

Haha, I like the way you think!

While at it I wonder if it's possible to dualwield Shotguns as well, or if 2-handed weapons really do take two hands.

 

If you've ever played Diablo 2, barbarians can wield 2 handed weapons in one hand, but the stats would be weakened.
I think that, if you get past a certain part of the game, you should be allowed to wield a 2h weapon in 1 hand, but the power would be decreased.

 

A crab launcher, for maximum damage.

 

A piranha gun! that shoots piranhas!
