"Well, I could hit you with the wrench end, or stab you with the knife end. Knifewrench! For Kids!"
— The Janitor, Scrubs
...I'm pretty sure the creative process behind making (the weapons) boils down to taking a preexisting weapon, putting a gun in it, followed by the phrase "Cause Why The Fuck Not?" Just from what we've seen we have a rapier that can use magic and shoot ice and other shit - "Cause Why The Fuck Not?", a red death scythe that doubles up as a massive fifty-cal sniper rifle - "Cause Why The Fuck Not?", swords that can be shot and gauntlets that fire shotgun bullets - "Cause Why The Fuck Not?" and finally a baseball bat that fires grenades and can also be used as a bazooka. So, with this in mind I suspect the weapon of the final villain will be a lightsaber that is also a gun that shoots more guns that doubles up as a bazooka that can transform into an Apache helicopter. And, if that turns out not to be the case, well get on it Monty! "Cause Why The Fuck Not?"
