Hadouken wasn't a weapon...
One that sticks out is Broad Legged from dotHack//GU. It's a giant fricken chainsaw sword of death. DotHack//GU had a lot of really awesome weapons like that.
Another is Soul Edge from the first Soul Calibur. A biological sword with a eyeball that looks upon you...a fricken demon sword that's actually a demon itself!
