It is simply known as The Doctor. It's like a minigun, except it has 200,000 barrels, each of which is 12 feet in diameter. Each barrel fires a small concentrated burst of hypothetical energy, which transforms into physical being as anything in the known universe once it reaches it's target. Sometimes it's bullets. Sometimes it's an animal. Sometimes it's an ancient god wielding a magic sword. ANYTHING IS POSSIBLE. However, whatever the projectile becomes, it is always on fire. Each barrel fires at approx. 500 trillion bursts per second, and it never runs out of ammo. It contains within it several black holes, some antimatter, some regular matter, some dark matter, some neutral matter, about half of the time vortex, thousands of small parallel universes, and a small capsule of Satan's blood. Every time it fires, somewhere in the universe, a star explodes and a criminal realizes the error of his ways. It also exists exactly one second in the future, so it knows what you're going to do before you do.
I could keep going, but I'm getting bored with this.
