Your weapon? With a .....twist?

[Sangtrain]

A Vorpal Bastard Sword that causes the decapitation at any target it is swung at(as in you could swing at their toes and it would cause their head to roll)

problem is it attempts to Behead it's owner when it is unsheathed and not swung constantly.

 

[Riddle78]

A Zweihander that's perfectly weighted and balanced to my person,and will adjust itself in every shape way and form according to me.
Downside? Every time I strike a living thing with it,its hilt heats up,and will only cool down if I drop it in the heat of battle.

 

[Simalacrum]

A super hover tank with a plasma cannon and chainsaw launcher.

Downside: It runs on Justin Bieber albums. You have to play them to power the tank.

You evil, evil man.

 

[jamradar]

A gun that shoots out dogs.

 

[katsumoto03]

A gun that teleports my enemies into the future.

Downside: It only sends them one second into the future...

 

[Doinstuffman38]

A gun that shoots chainsaws that explode on contact into balls of fire ants on fire.

Downside: It has a short range, and the flaming fire ants do not recognize friend from foe.

 

[DragonChi]

I so badly would want a big gun that, would make people think it would blow up the planet with one shot..but when u pull the trigger..all it does is shoot out a hand holding an large trout and slaps you across the face with it and then retracts.

 

[WOPR]

a Gun that can shoot Shurikens and Lightning
downside it could only be more awesome if it had breasts and was on fire

BUT THAT WILL NEVER HAPPEN!
(lol just kidding)

I'd have to say extremely powerful mech arms, downside, you have to amputate your own to use them

 

[TheYellowCellPhone]

A battle hammer that causes me to go into a coma every time I use it.

 

[garfoldsomeoneelse]

I keep having these weird dreams where I'm getting cheated on by this girl I'm not dating in reality. So I suppose I'd just make a monster as a physical incarnation of my insecurities; I believe the only way to describe the result would be "Eldritch Abomination".

The downside is that casual analysis of my dreams will show me just how immature I am.

 

[Singularly Datarific]

A nuke, but the catch is that it isn't actually a nuke, but a very detailed model of a nuke that the retailer sold me (Cheapskate).

 

[ZeikHunter]

My weapon would be a magic fountain pen that will make whatever I think come to life.

The downside is that I'm a closet pervert, so nude women would be my only resource.

 

[Sn1P3r M98]

Deathstar it's pretty much unbeatable
I mean there IS a two meter wide whole that if you MIGHT get a torpedo down could blow it up.
But it's ray sheilded, has enough guns to kill a whole army in three secounds flat and has a dark lord of the sith guarding it. I think I'm safe

I used to T-16 womp rats. I can totally nail your 2 metre thermal exhaust port.

OT: Vicious weapons in DDO. They deal an extra 1d6 to your target, but hit you for 1d3. Not bad if you have a healer or are fighting weaklings, but get yourself in a one on one with a monster with 10 times as many hitpoints as you and odds are good you'd be in trouble.

Oh yeah well I'll uses super advanced homing missiles to blow you outta the sky flyboy!

wait they need a twist...Umm well they are homing missiles. Say good bye to your house!

I expected homing missiles, so I set up a missile defense field. Shame that it makes everyone in the house vomit everytime it blocks a missile...

Que simultaneous family vomiting!

I can cloak on command. Downside: I can't be wearing any clothes while cloaked.

 

[CouchCommando]

A flame thrower disguised as a sniper rifle!!! they think that the best way to take you out is to get in close and WHOOOSH!! bbq.

 

[Elric Randall]

Amazing, slap-away-the-bullet karate powers that only work when I'm too depressed to get outta bed.

 

[ZeikHunter]

A needle rifle, but the downside is that the crystals are radioactive even when they're in the gun!

Since I'm thinking of this, the pen draws a second one so I get DOUBLE RADIATION!

 

[Elric Randall]

An array of magical creatures that can be summoned from small red-and-white orbs, each capable of anything from flight to water travel to telekinesis.

The downside is that none of the creatures can stop a bullet and still live.

 

[Siege_TF]

Plasma pistol. Gets Hot! I don't have an armor save. :<

 

[Elric Randall]

A book containing all knowledge, allowing one to reshape matter with a thought.

The downside being that the book can't be read, of course.

 

[Boom129]

transforming blade, default form thin bladed short sword with many thick, wave shaped "thorns" coming out both sides capable of catching a blade or slicing off more enemy with each hit. Weakness is it can only be used for melee. (though it can transform for long reach)
