John Spartan. The Demolition Man. The original 117 (That was his cell number when he was in stasis, lol). Course, Chief has a ton of stuff in his advantage, but it'd be cool to see two action heroes face off.
Jimmy Johns is too freaky fast to keep track of. He's a hunter in the night, picking off the strays until the scared survivors form a group to try to take him out, but to no avail. They can't beat Jimmy Johns because not only is he freaky fast, he is also freaky good.
Dont bother screaming, dont bother crying, ignore all hope of mercy. Oh my God, they're everywhere.
