Yeah, that hidden one he has is pretty cool.

Hands down, The uber version of Gravity Fun from HL2, i mean com'on, what's there NOT to like about it.
If you were offered one, there's no way you could reject it.
Too amazing.

probably Dai-Jo staff in beyond good & evil or a blitzball in final fantasy x

haha yeah Wakka's blitzball in Final Fantasy X... good times

Real-world: Browning M2 Machinegun. Held the world record for longest range confirmed sniper kill for 35 years. (huzzah for Carlos Hathcock)

Fictional: Bolter(Warhammer), Elven Courtblade(D&D), Uriziel(Gothic1), Punishment(FFVIII).

It gotta be a lightsaber

Sour cream. If you cram enough of it into somebody's throat....

Actually... video game wise, it'd have to be the enemies from Kirby's Adventure. Or maybe it's Kirby's stomach... whatever that allows him to gain powers from others.

BFG9000 from Doom. Best.weapon.ever.

Or Blaster Chaingun, it can blast walls off.
Or the Death Star, it can destroy planets.
Or a halo ring, it destory universes.

Gotta be the archers ; )
