Your ultimate weapon.

Mother of God...

 

Dafuq? If I had an unstoppable super weapon I would use it to defend myself as much as I possibly can.
My super weapon would be a Laser Gatling Gun, shooting lasers and smaller laser gatling guns. Yes, it's an endless gatling gun storm.

 

No weapon, i would just jump on everything's head.

 

What is this? Muramario?

 

Possibly... Also, as Amnesia has reminded me multiple times, a chair is not a valid weapon.

 

I would use a......Kero Ball!!!
(any one get the reference?)

 

Mine would be an airborne regiment of midget wrestling zombies that would parachute in and take care of business, one small bite at a time!

 

The heat seeking intergalactic ballistic anti-plasma missile
EDIT:It can(and has) wiped out entire races by destroying entire planet systems.

 

An army of kamikaze manned nuclear missile pilots.

 

2nd ultimate weapon a robotic Tri-raptor which fires plasma, lasers, poison gas, flamethrowers, and grenades.

 

A broken beer bottle. Bash some brains out in a violent manner!

 

Bass Cannon, feel the power of MUSIC!

 

Both of my Uber weapons destroy everything remotely near them. Why would I constantly blow up planet systems with my anti-plasma missile or wipe out ecosystems with my Robo-Tri-Raptor?

 

An giant, uber-charged Gravity gun that can fling planets and stars around

 

We all forgot the most simple yet destructive one.
teh nuke.

 

Legendary Electrified Yataghan! Sooooooo EPIC!

 

A giant katamari

 

I would use the power of "modding"!

Erm... well, get a friend who knows how to do that...

Or maybe a... Gundam!

Oh, that's 2 weapons. I guess that's cheating. Wait! I'll use the power of...

CHEATING!

 

A sonic death ray.

 

A fish.

as long as you don't make copies of yourself, you should be k.
