What is your video game weapon?

What is your choice of destruction? Do you prefer the traditional sword in melee combat? Perhaps deadly magical fire balls suits your fancy. Whips, clubs, fists, guns, giant stuff panda bears, whatever you think would be the most awesome weapon on a character. Tell us about your ideal weapon and what kind of special effect (if any) it could bring.

I want grenades that can cause miniature black holes that act like a map hazard. Obviously it would have to be limited or you'll break the map (then again maybe the map transitions to deep space...)

 

Lu Bu's Sky Piercer which has killed millions, and probably throw in Commander Shepard's N7 Armor.

 

Does a lightsaber and cool force powers count?
