"Back off, I have a shrinkgun! Do you want to be shrunk? No one wants to be shrunk. That's the point, it's a shrinkgun! Back off!" - Myron Reducto.

[cryogeist]

a huge drill that gose into the middle of the earth and plants a nuke f with me and the planet goes boom im in control

 

[flipsalty]

Mass hydrogen ping.

Which once released into the air would separate the hydrogen atom from oxygen leaving huge pockets of pure fuel grade oxygen in an area that could probably be ignited from the sun's rays alone. Which could probably cause a catalyst in a body of water and then in less than a second the entire Pacific could be a literal ocean of fire.

All in all game over.

Hydrogen and Oxygen make water, not air. Oxygen is already in its base form in the air and yet no spontaneous explosions. And it would be impossible to split them in liquid water, oxygen turns to gas at -300F and hydrogen at -400F. So you're better off freezing the planet.

I would bring back the dinosaurs, make them bullet proof, unleash them in a major city's , and wait

My afro laced with poison. People go "oh awesome, can I touch do it?!" I say yes, doing a mild maniacal laugh and as they touch it they die! MUHAHAHAHAH!

That or a zombie army.

 

[viking97]

Or a Lombax cloning program.

dude you'd only need like five. that would be enough. you just have to be sure they're all EVIL.

 

[Withall]

Hmhm... I'd go for a "hairline-cracker" machine. Just make hairline cracks in reality. Make all sorts of stuff happen. Sudden gravity shift, anyone?

 

[Captain Pancake]

For that I am glad that the world cup is over and won't be gracing south africa for a while.

Well quake 4 had the dark matter gun, which did the same thing.

2 space cannons either side of the earth, aimed at the center, 1 firing anti-neutronium and the other firing neutronium.

[viking97]

A genetically modified, poisonous super-algae. One that flourishes in fresh and salt-water of all temperatures and environments, and expands/multiplies at an exponential rate. It would spread across the world's water supplies within months and ultimately destroy all life.

Of course, I would hold the world at ransom before I unleashed it! MUAHAHAHAHAHAHAH!
