If you could have any video game weapon...

This is tough... To choose, I'd say any of the following:
Link's Master Sword: OWNAGE!!
Starman: I cannot be owned.
Gravity Hammer: Must I say why?
A Car From "Burnout": Those are weapons if you like it or not!
Maple Dragon Sword: Best. Maple. Weapon. EVER.
Beam Sword: Again, must I say why?
Shotgun: Simple, but effective.
Extreme Gear: WHACK! Did that hurt? Now I run- I mean ride!
Plunger: No reason! *cough* DAHHHHHHHHHH *cough*
Koopa Shell: Once again, simple, but effective.
Kirby's Warpstar: Boosh.
Boringness: Ever play "De Blob"?
Arwing: DO A BARREL-ROLL!
That's it. I'd pick ANY of these weapons. There are others, but I can't think of them. Later!
