A/N : I wrote this story for Halloween and completely forgot about it, heres the prologue, the basic premise is that chuck is kidnapped by a mad genetic scientist and is experimented on and it's up to Sarah and Casey to find him. First chuck fic, hell this is my first fanfic, apologies for any mistakes.

Prologue

The beast loped quickly through the forest making no noise, radiating such an aura of danger that any living thing its scattered out of its way. This forest located in a small village, and never before had a creature such as this. Every animal knew on an instinctual level that this beast was unnatural, it was dangerous and it was hungry. It moved through the forest with deadly grace, claws glinting softly. The beast howled, its desire for blood and food lacing the inhuman sound. It kept its inhuman speed until it came up to a wide river cutting through the forest. It stood up on its hind legs pulling itself up to its full height of eight feet, covered from head to toe in brown fur, long fingers ending in sharp claws. A large jaw jutting out life a wolves' muzzle filled with razor sharp teeth covered in fresh blood.

It walked over to the river, crouched and drank greedily, drinking for the first time since its existence.

It stood once more, tilted its head back and let out a howl of blood lust.

Its ears twitched picking up a faint rustling of leave and soft footsteps. It turned around and crouched readying for a fight gazing into the opening in the trees.

Sarah Walker was rational woman, she knew people, she was aware of the dangers of the world. Hell she fought her fair share of psychos, murderers and terrorists, she had a firm grasp of the reality of the world she lived in. She was a conman's daughter, and now an agent of the CIA, she had seen it all and more. There were few things that unsettled Sarah Walker.

This was one of those "few things".

Jesus Christ, Jesus fucking Christ! Sarah ran a hand through her hair taking a deep breath and calming herself down. She was Sarah Walker "bad-ass ninja girl" as chuck had dubbed her, CIA agent, she had faced hairy drug dealers, treasonous spy organizations, arms dealers, and many of Awesome's outings. She was not afraid of anything.

So she gathered herself up and continued through the forest , gun gripped tightly in one hand and GPS in the other. She patted her front pocket to make sure the antidote was still there. The dot on the screen that indicated the targets was moving incredibly fast, if anyone else looked at the screen they would assume it was a car. But Sarah knew what it was, it was the beast, she continued walking hoping to intercept it. Thinking of it set another jolt of pain through her, she steeled her breath trying not breakdown, she could still fix this, fix him.

She glanced at the GPS again and found that it had stopped moving. She moved quicker through the forest until she came to the edge of the clearing of where it was. She crouched down behind the bushes and peered over it. The moonlight swathed the clearing in an eerie light glinting softly of the river.

There was nothing.

This didn't make sense it was supposed to be here, she checked the GPS. The large blue dot was there exactly where she was it blinked at her mockingly. She looked at the clearing more closely. She gritted her teeth, panic beginning to settle in her . Damn it, it was supposed to be hear it was-.

She spun around quickly gun gripped tightly in her trembling hand. There was nothing behind her, she let out a relived breath. There was nothing there, she let out a panicked laugh. She's been watching to many horror movies with chuck, what are the chances it would be right behind her, what idiot would think-

Sarah felt a warm breath tickle her exposed neck and froze, she heard soft breathing behind her. Gun gripped in her trembling hand she turned slowly.

Sarah found herself staring into something straight out of hell. Long snout, enormous teeth, and the eyes, oh god the eyes, blood red and full of hunger.

There was a scream, a gunshot, and a roar of inhuman anger.

so? good, bad? should i continue?
