-Four months before Dean was sent to hell-

Screams and blood that was all I have ever known. Being the child of a demon that was the environment I was raised in. Alastair had one pet project, one that he was working on for 24 years. A born demon, you see demons aren't born like humans they are made. So having a born demon must make them even more powerful than any other demon in hell.

It was true to an extent, I was powerful but I had a soul. The demons used human bodies so when I was born onto this earth I gained a soul. An with my soul I used all of its pure power to pray to god. To save me from a fate I had no part in. In hell I prayed every night to be set free. It never happened until 24 years after my birth that someone heard me.

"Why do you pray demon?" A voice called to me from up above.

I looked up and smiled a sweet smile. Someone finally could hear me.

"I am not like the others. I was born a demon but I have a soul. I am bound here but I wish to live a mortal life. I wish to be free of this cell to do some good in the world. Please angel will you help me?" I asked waiting for an answer.

"Why should I help you? You are a demon spawn of one of the worst demon torturers know to our kind." The voice replied.

"I will give you my soul. I will bind myself to you so I can do no harm to an innocent. I will do anything you wish just please free me from this hell!" I cried and fell to my knees.

"You will regret your words demon I promise you this." The angel said and pulled me from hell.

It felt like forever while I was being pulled up from hell but when I finally fell onto the ground it hurt. I looked around and saw a field with wild flowers growing all over. Then to the left of me there was a man with short spikey black hair and a trench coat.

"I am Castiel an angel of the lord." He said and walked towards me slowly.

I looked at my human body. Light brown skin, hair down to the floor as dark as demon's eyes, really large breasts…like ridiculously huge. I just shook my head and turned back to Castiel.

"My name is Mackenzie but you may call me Mac." I told him and smiled.

He dug around his coat pocket and pulled out a chocker. Just a little black chocker with a cross on it.

"This collar will bind you to me. You will do as a I say when I say and protect or kill who I say is that understood." Castiel said and opened the collar to put around my neck.

"I understand completely Castiel. I will obey." I told him as he placed the collar around me. I would do anything for the angel that set me free.

-Two months after Dean came back from hell-

I woke up in my motel room, stretching my arms and legs. I knew that Castiel wanted me to find the Winchester brothers and protect them but there was going to be a small problem with his plan.

I dressed in black leather biker boots, black jeans, bindings on my breasts to make them as flat as they can, black cotton button up shirt, a black bandana over the lower part of my face and a black cowboy hat. Over all of this I wore a long black leather duster. For some reason I still couldn't get the walk down. Didn't need people to realize I was a girl because I couldn't keep my ass in line. In this outfit I was Mac, the man. No one saw me as the woman that I was. An since my voice was a little too high pitched I couldn't mask it. So I never spoke in front of others.

I walked out of the bathroom to see Castiel. He looked at me and I could see that he needed me for something. I walked towards him and waited for him to tell me what he wanted me to do.

"We are going to save the boys. Come." Castiel said to me and walked towards the door. I nodded and followed him.

We basically flashed towards the location where the boys were. They stood surrounded by demons. You could tell that they have gotten the shit beaten out of them and they were on the last bit of their strength.

Castiel looked at me and nodded. I grabbed my two tonfa blades; blades that were held off to the side of the handle so the user can swing them in their fists.; and charged. I killed two demons with one swing. Dean and Sam turned to see me, not knowing what to do. I walked towards the others and stood in waiting.

The last few demons just stared at me for a second then they ran away. Leaving the bodies they were riding on the ground. I smirked and flipped them off.

"Mac!" Castiel yelled at me. I bowed my head in "shame" for the bad thing I did but on the inside I was laughing my ass off.

"Cas what the hell is that?" Dean yelled as he pointed at me.

I would be hurt if I cared that much. I looked towards Castiel waiting for an answer.

"This is Mac, the demon I told you about." Castiel said as he walked towards me to make sure I was not hurt. He looked for any cuts and nodded his head.

"Yeah well I didn't think you would find some Nightmare on Elm's Street reject to be your little man slave!" Dean growled as he too looked me over.

I arched my eye brow and sighed. I mean I knew Dean was going to be hard to get along with but seriously why did he have to be such a little girl.

"I'm Sam." Sam introduced himself and presented his hand. I shook it welcomingly.

"You don't talk?" Sam asked me as we let go.

"Mac has no reason to talk therefore Mac doesn't speak. Now let's get back to Bobby's I have much to tell you." Castiel said for me and grabbed all of us.

When I opened my eyes I saw that not only was I in a devil's trap but we were in an old house. I sighed and sat down on the ground while the others dealt with what they needed.

"Boys what the hell is that?" Bobby screamed and pointed at me.

"That is our tamed lion Bobby. Meet Mac the friendly demon."Dean replied and patted my hat.

I growled at him but continued to stay sitting.

"Do not tease Mac. I could take Mac back with me and you will be left without a guardian." Castiel warned.

"I don't need some body riding bitch to protect me and Sam." Dean yelled.

Before Castiel was able to reply I tensed and looked towards the window. I had to think of something. Something to protect them from the Witness that were coming. I thought quickly and then realized that they maybe able to find a way to stop them but I knew a quick way to do it. I turned to Castiel and snapped my fingers.

The ground shook, the lights dimmed, the floor boards started to crack and give way to what I summoned.

"What the hell is he doing?" Dean screamed.

"This is why you don't piss off a demon Cas brings you dumbass!" Sam screamed at Dean.

I watched as my Cerberus climbed from the pit to do what I commanded. It stood up in hellish glory. Three heads ready to attack. I smiled and created the symbol into the wood I was standing on. I pointed to it and made the killing motion by moving my index finger across my neck.

Cerberus barked and I snapped my finger again. He howled and ran out of the door. Chasing after the Witness to protect the people inside.

"What the hell was that?" Bobby asked looking through the whole that was his front door.

"That was Mac's hellhound. You did not tell me that it was Cerberus." Castiel said to me.

I shrugged my shoulders and watched as he ran all through Bobby's lot and destroyed some of the Witness that were out there.

"What is it doing?" Sam asked.

"It would seem that someone summoned The Witness and Mac is making sure that they don't do too much damage." Castiel said as he walked around the devil's trap.

"I think it would be best if you let Mac out of the trap now." Castiel told them as Cerberus came charging back into the house.

Sam walked over and scrapped a little of the paint off the floor. I walked out of the trap and petted Cerberus for a job well done. I knew there were more around but now at least we have a few of them destroyed.

"Will Cerberus attack us?" Sam asked as he watched the two of us bond.

I shook my head no and grabbed Sam's hand. I placed it on the center head and made him rub the fur.

Sam's face went from fear to joy in seconds. He could see that besides the fact that this dog has three heads and smells of brimstone it was pretty much a normal dog.

Sam got down onto his knees and petted all of the heads. Cerberus started to lick Sam's face but due to the fact that there were three heads Cerberus knocked Sam onto his back and he basically started to lick attack him.

Dean and Bobby just watched as a hellhound of legend, the one hellhound that every creature feared, was being a puppy and playing with Sam.

"Son of a bitch." Dean whispered. I looked at him and started to shake my shoulders in laughter.

"What's so funny?" Dean asked. I just shrugged my shoulders and walked into the kitchen. I was going to get something to drink but I stopped. I turned and walked to Bobby. I pointed to his sink and the cupboard that held the cups.

He figured that I was asking for a cup of water.

"Yeah go ahead." Bobby said as he watched me grab a cup and fill it with water. I drank all of my water and then washed the glass. I dried it and placed it back where I found out.

I took a notebook out of my coat pocket and wrote the words Thank you on them.

"You're welcome." Bobby replied.

I stood there watching Cerberus snuggling into Sam.

"This dog is awesome." Sam told me as he hugged Cerberus.

"That's great and all but how are we going to walk around with a hellhound with three head that normal people can see. What's your plan now Mac?" Dean questioned with a smug smile on his face.

I rolled my brown eyes at him and snapped my fingers. Cerberus came to me waiting for commands. I turned my eyes black and held my hand over him. He glowed and the turned into a shotgun. I put him in his harness that is around my leg.

I grabbed my notebook and pen again and wrote. "Now what douche nozzle."
