1) Spartan- Snce there Society depended and was dedicated to Military service and this weapon derived it's name from their tactics, It would be natural that the Spartans would use the Phalanx CIWS. This is one Bada$$ 20mm Gatling Gun. Fit for the Ultimate fighting man.
2)Lady GaGa- This is one crazy B**ch, A woman with this much wacadoo stylings would be an FMG 9 it could be incorporated into the Stupid Clothes she wears.
3)Klingon- Being a Warrior Society, much like the Spartans. They would be dealing with a Futuristic weapon system. They would bring out MTHEL(Mobile Tactical High Energy Laser).
4)Gary Busey- This Man, he needs no Weapons but that of his wit. His own Son has said, "He's always telling stories about monkeys and toads and rockets. I can never understand what he's talking about."
Anyone that says stuff like this, "One night...at [the hospital], I was sitting in bed...and saw the Grim Reaper standing in the corner. He was seven feet tall, with a brown robe. He pointed to me and said, 'Relax, it's not your time to go. You have been given gifts. These gifts are ready to be received by mankind. So get on your feet and improve.' Then he laughed, spun his scythe and left. I wasn't asleep and I hadn't been for days. Whether this was a premonition or an angel in disguise, I don't know.", Needs no weapon. Besides who wants this man with a gun.
5)Cajun/Bayou guy- I have no other reason than I just picture some Cajun Boating around the swamp with a Mossberg .410 Bolt Action. It is just the image that pops into my head. This Guy with this Shotgun.
