The battle against the ultimate demon begins, and Castiel and the other angels are in for the fight of their lives.


Castiel and the rest of the angels watched as Dean's skin got darker and darker, his form solidified, even his hair and clothes turning to molten stone. He struggled against it, grunting and growling. But the rock got harder and harder, and there was silence as Dean became trapped on his own skin. The angels were still, poised as if waiting for the inevitable shock wave. Nothing happened. They started to relax.

Castiel examined Dean. That couldn't have been it, could it? He took a step closer, into the elaborate devils trap. He froze. He could have sworn that the statue of Dean had turned it's head. He knew he wasn't mistaken when it did it again. Dean's head gave a violent jerk, a crack appearing along his neck with red light gushing through.

"Prepare yourselves!" Castiel commanded. "Show no mercy!"

The red light spread to Dean's body in an elaborate jagged pattern. The individual stones separated as Dean's form grew larger and larger, molten lava flowing underneath. His clothes burned off, and the more Dean thrashed around, the brighter his inner light seemed to glow. Dean's feet had morphed into cloven hooves, horns had sprouted from the top of his head and curled over his head and under his ears. His lower jaw jutted out more than his top, the teeth growing in length.

The entire building shook with Dean's every growl and roar. The holy water icicles directly above Dean started to melt, and the cold water that rained down on him turned into steam, but didn't seem to bother him in the slightest. He was almost to the ceiling now, his features completely unrecognizable as the man he was before. His roars died down, and Dean eventually stopped thrashing. He slumped over and didn't move.

Castiel felt a strange tugging at the very core of his being. Confused as to what was happening. He looked at the other angels. The looks on their faces told him they were also experiencing the same sensation. One of the angels gave a yell, and Castiel turned to see that angel breathing hard, clutching her chest. A small glowing white orb was floating in front of her. The woman starred horrified at the soul floated towards Dean, and went through his flesh. That woman's face appeared on Dean's molten skin, her face twisted in agony.

Dean's horned head lifted, a low growl shaking the foundation of the building. More souls were being ripped out of the angels vessels, and all were encased within Dean's fiery bowels, and the more souls that he took in, the more awake and alert Dean became. It was soon apparent what exactly Dean was.

He wasn't just a demon. He was the living, breathing, walking personification of hell. Fire, darkness, and eternal torture; all were encased in Dean's body. He didn't have a consciousness like his other demon form. Then he had wanted to destroy the world. Now, all Dean wanted to do was capture as many souls as he could and lay waste and havoc where ever he went. Hell walking, the sky would bleed and the oceans would dry up.

But first he had to get through these pesky angels.

Castiel felt a final yank in his being and gasped in pain as Jimmy Novak's soul was ripped from its body. As soon as the soul was out, Castiel immediately felt his skin start to tingle. Now that Castiel didn't have a human soul in his vessel to keep his angel powers in check, Castiel's angel power started to have effects on Jimmy's body. Other angels were experiencing the same. Silver light started to branch over their skin, and wings began appearing feather by feather. Castiel knew that it would not be long until his powers over came and destroyed his vessels body. They had to act fast to free their souls from the fiery depths of Dean.

A few angels were already flying around Dean, searching for weak spots and None of them dared attack the torso or chest, where the souls of their vessels were being stored. And besides, that part of Dean was completely made up of fire. Only Dean's hands, hooves, and head were covered in hard stone. As Dean walked, the holy water icicles melted and splashed to the ground, drenching the rapidly changing Castiel.

His form was growing taller, and he could feel his other set of eyes beginning to open up just underneath his other ones. The hair was falling off, and soon the clothes were burning away as well. His skin was giving off a white light, and it soon became overwhelming. Castiel knew that if he didn't keep himself under control, then Jimmy would never be able to reclaim a place in his body.

Castiel concentrated hard and tried to minimize the overflow of angel power. It slowed a little, just enough so that he wasn't growing anymore, but he had gained about fifteen feet in height.

Other angels were barley able to keep their vast powers under control. Especially those battling Dean. They had concentrated their attacked on a large jagged crack that ran over Dean's right eye, on his brow.

Dean howled and started to grab at the small pesky white flying things that were attacking his head. He knew what they were, and he also why he didn't like them. Stupid little pigeons that thought they were so much better than everybody else. Annoying, obnoxious, pompous jerks. But they were no match for him. They could never kill him.

Castiel took off and joined his brothers and sisters in the fight. He arched high and came soaring back down, his fist drawn back and collecting much of his power into that fist. Castiel started to pull away at the last second, and flared his wings out. He threw his fist forward, and there was a white shock wave that emanated when his fist collided with the rough stone.

Dean roared and fell backwards on his back. He lay still for a while, and the angels watched, waiting for signs of life. They landed and hunched over gasping for breath. Castiel felt a small trickle of blood at the corner of his mouth. That hit had taken a lot more out of him than he had estimated. He had to keep some on reserve. But then again, maybe not. Dean hadn't moved.

Suddenly, with surprising speed for his size, Dean lurched up and forward. Roaring with all his might, Dean jumped, breaking through the roof of the warehouse and into the sky above. Without hesitation, the angels followed him through the hole.

Dean landed in one of the abandoned lots of the warehouse, the different storage containers stretching left and right. Angels landed on the roofs of the containers, surrounding Dean. Castiel flew above, examining the enormous creature. Castiel grinned when he saw what he was looking for.

Surely enough, there was a small, slow and steady leak of bright fire-orange blood dripping from Deans brow. Excellent, they had drawn blood. Now all they needed to do was collect a little, and remove the demon essence, soul, whatever it had become, once and for all.

Castiel dive bombed Dean, crashing his other fist into the side of his face. The other angels did likewise and took off from the roof. Dean tried to snatch and grab at the angels, like king kong with the airplanes at the top of the empire state building. He had managed to knock one angel out of the sky and into one of the storage units. Empty tin cans scattered across the ground and around Deans hooves.

The angles continued to bombard and barrage Dean with blows, and each and everyone of them had empowered their fist with their knock-out powers. On humans it only took two fingers. This was going to take a lot more than that. The angels were fast and agile, and could easily land a touch. But Dean was strong, and not even after fifty blows did he seem phased at all. Castiel was beginning to wonder if taking this thing down was even possible.

Dear god, please help us. Castiel prayed, which he thought was what all the other angels were doing. Some angels were beginning to tire, and were lagging in their maneuverability, making it easier for Dean to smack them out of the air. Castiel was one of only a few flying angels left, and Dean was still coming on strong, fueled by the souls he kept trapped in his bowels.

Castiel's vision was beginning to waver, and before he knew it, Dean's large clawed hand came whooshing towards him. He was spinning and falling through the air, and he hit the pavement with a loud crack and a small crater in the earth. Castiel stared up at the sky, blackness swimming at the edges. There was to way to take down this creature, this monster that was made up of fire and pain and suffering. Castiel prayed for help one last time. As he expected, nothing happened.

He heard Dean give a roar. But this was unlike any roar he had given before. It was filled with pain and surprise. There was a loud bang, and the earth shuddered beneath Castiel. Castiel managed to chase the blackness away one more time, and lifted his head to see what it was all about.

The huge demon was lying on the ground. His eyebrow was bleeding profusely, and there was no conscious light behind his eyes. Castiel looked around to see who had caused it. One light very far off in the distance, fading very fast, told Castiel all he needed to know.

Michael.

As if on queue, a booming voice whispered in Castiel's head; take care of him, my brother.

Angels gathered around the fallen demon, breathing hard, and some even cradling wounded limbs. One took a hand and dragged it across the earth, creating a large circle and pentagram around the demon. Before getting ready to do the extraction ritual, Castiel took one of the tin cans on the ground and went about to the demons head. The bright orange blood leaked out of Dean's face and across his forehead into the ground. Castiel let a couple of enormous drops fall into the can, which was enough to fill it halfway full. He then sealed the can and stepped out of the circle. The angels began chanting, and Dean's hideous demon form began to evaporate, the red and black smoke collecting together in one ball above him.

When the ritual was done, and the essence had finally been cleansed from Dean, one of the angels collected it in a silver canister.

Dean was lying on the ground, and somehow his clothes had all survived the ordeal. His skin was gray, and his eyes were moving behind his head. Castiel lifted on of Dean's eyelids to see that his iris was a swirling mix of gray, green, blue, and brown. Castiel looked down at his form. Removing the souls that were trapped in Dean's body was not going to be easy. Do-abble, but not easy.

Besides, now that Dean was stable, and his regular essence levels had been restored, it wasn't like anymore bad things could happen.

Right?


A/N: I'm evil, I know. So what do you guys think? Honestly, it could go two ways from here. Dean could return to normal and Sam would get cured, they live happily ever after (somewhat). OR I could shoot out a whole other story line that would take you further on this adventure with out favorite hunters. Comment and tell me what you would like.

Yay, Castiel got a chance to change into his true form. I don't know where I got the idea of four eyes, but he said in one of the new epsiodes this season that his true form was about the size of our empire state building? Idk, but he's tall. Sorry for any grammatical or pelling errors. Read, review, and enjoy!
