Im going to go with InuYasha on this because his Tetsaiga has a power to shoot diamonds. But i don't know why no one picks them up after the battle, then they complain about money (Facepalm)

Naota Nandaba and his flying V.

The pink dildo Chuck Greene can use in Dead Rising 2. Why? IT'S A MOTHERFUCKING PINK DILDO AND YOU KILL ZOMBIES WITH IT. 'Nuff said.

@Kaheliini you havent watched Panty & Stocking yet huh? they take "killing Zombies with pink and green dildo's" to a whole new level in one episode.

@break Actually I have, I just didn't remember that particular scene :D Well, the bottomline is that dildoes make great weapons.

at least against squishy Zombies.

Fact: If it's an epic weapon, Gilgamesh has it's original inside his Gate of Babylon:

Also, he has a chain called Enkidu which can bind even gods, and Ea, an anti-world (!) weapon.

However, his most powerful weapon is his body:

@Akidzuki a little correction: his chain cant bind EVEN gods, it can bind ONLY gods. its effectiveness rises the more divinity you have and sinks the less divinity you have. so a god could never escape it, while a normal human could with ease. or a squirrel.
