http://www.comicfic.net/fic/andrea/baaad.htm)
Author: Andrea
Fandom: Marvel (X-Force from long ago)
Character(s): Cable, Domino, X-Force (Cannonball, Boom-Boom, etc.)
Author Summary: Cable confronts an unknown mutant and, well, things go baaad.
Review: This fic made me laugh so hard when I first read it. you don't have to know a lot about X-Force from ages past, if you know that a) Cable is normally a bad-ass man who carries big guns and that b) Cable and Domino's relationship is made of love and snark (a whoooole lotta snark), then you're pretty much set. The rest will fall into place, and if it doesn't, you won't miss out on the amusing nature of the fic. Go read!
Excerpt: Nathan Summers, also known as Cable, volatile leader of the mutant vigilante team X-Force, was infected with a techno-organic virus as a small child. He'd been sent into the future in hopes of a cure, and in lieu of that had learned to control the virus with his telekinetic powers. Today he'd finally been cured.
He always thought he'd be happier about that.
