Ooh i love this thread!
lets see...
Real World
5. Taser- Scare the crap out of your friends! Watch both friends and enemies squirm helplessly on the ground for AS LONG AS YOU WANT! Make really funny drunken home videos! Lose your ability to procreate/taste/see/smell!
4. Throwing Ninja Stars- hold 6 of em between your fingers, arms crossed in front of your chest, fling outwards. That would look so badass. Throwing stars or kunai... either one
3. Sawed off shotgun- need i say more?
2. Broadsword- You know it would be SO badass to walk down the street with a big ass sword strapped to your back or slung over your shoulder. something bigger than you and heavier too. put on some 300 rock and go in slow motion and you could get any girl on the planet
1. Katana/Dual Katanas- as Tweedy said, Katanas can defeat any other weapon! Doubt me? Watch Rurouni Kenshin. All you need is a Katana and a mastery of Bato Jutsu and you can dodge bullets!
Fantasy
5. Halo Battle Rifle- not the most powerful weapon, but comeon, anyone sees you holding Mastercheif's weapon and they'll cooperate.
4. Phaser- ITS GOT SETTINGS! You can use it like a taser for some semi-harmless fun, or obliterate someone!
3. Nuclear gun from the Foundation novels- instant desintigration anyone? and not only on people, think of how it would help our trash situation?
2. Athena's Blades lv. 5 from God of War II- extending swords that also give you kick ass, semi-slow motion specials, other really fast specials, and glow red.
1. I'm gonna go with the lightsaber here. I dont think i need to explain myself
Honorable mentions- they almost made it
Plasma grenades from Halo- same reasons as Tweedy's
Gears of War rifle/chainsaw- bam bam bam BRRRRRRRRRRRRRRRRRRRRRRRRR!
Whatever the thing was called from the Matrix that blinded Neo in the 3rd one. With all the electricity.
Napalm- *laughs maniacally*
Magic Wand- very cool, but wimpy looking...
The hundreds of metal balls from Aeon Flux, the stuff that took out the wall
Could Pokemon count? anyone would love to have one, personally i'd go for a Mew.
Sol Blade from Golden Sun 2- Megiddo!!!!
Tail from Alien... oh yea.
a Mage Staff
i have a lot of honorable mentions dont i?
