(AU, What if Michael and Lucifer wanted to stop the apocalypse, too? If they reached out to their destined vessels to help them? What would the Winchesters say?

Warning: Wincest! Sam/Dean/Lucifer, Michael/Jo in other chapters, not in first two chapters at least. Yes, it may get graphic and language does get worse. They do have sex in later chapters with one of their Angels hosts and Jo comes in and Michael falls in love with her, don't read if you get offended!

(For further clarification, the Angels do join with their hosts but do not take them over. They share possession of the boys' bodies. The room where they meet is a magic place they set up in between the boys' mentally so they can be separate souls, both the normal boys and the Archangels but in the end, the Archangel and the boy they are inside do function as separate entities at all times. They just use the same body to do it when not in the white room.

When I speak about the archangel, I am meaning the archangel soul. When It has the boys or Bobby's name, it is the person's soul that is in charge at that time. They coexist as two separate entities in the host bodies but therefore they are definitely different people in there, with separate thoughts and everything. Although they are more powerful when both souls work together to merge long enough to battle or something, mostly one or the other is in charge. A bit like Schizoprenia, but this time there really is someone in there with you.

If it says Michael is doing something, Michael's angel soul is doing it, not Dean's. If Lucifer is doing it, then it is Lucifer is doing it.

John does appear in later chapters, I promise. He is still a part of the boys' lives, such as they are.)

This is my take on how they could all put together to thwart the apocalypse and save their world and Heaven too.)

The two brothers stood facing each other in the field. It was a good day and the battle for the apocalypse was about to start. Hazel eyes met green eyes, as brother faced brother. They merely awaited their appointed hour to begin.

One month earlier

"You heard me." Sam repeated as Lucifer stood looking at him, no, at them, puzzled.

"You heard my plan, right? You know what this means, don't you?" Lucifer thought maybe the Winchesters had misunderstood. His demon followers were on the ground, dead, thanks to the tall man before him and his brother. Lucifer was glad; this talk didn't need an audience.

"I did." Sam nodded, "In return for my agreeing to share my body and mind with you by saying yes, you spare my brother, and those I love."

"Why?" Lucifer asked sincerely, this feeling inside him was something he hadn't felt before, confusion.

"I love them. They are my family. I want them safe so I will say yes if you won't let harm come to them." Sam said smiling sadly into his brother's eyes. Dean moved to his side and took his brother's hand.

"I get that, I do. I will be inside you the whole time. We will exist together, as two souls in the same body. Both equally in charge of it, but joined in purpose." Lucifer assured him.

"I get to be me still, right? You aren't going to possess me and make me do horrible things like the angels said you would?" Sam asked, Lucifer came up with worse plans than Dean did.

"Of course not, I don't want to destroy your soul, Sam. I want to share your body. Your soul will still inhabit the body and own it, I will just share the body and own it as well. Co-possessing it, sharing it but neither one of us actually owning it. They don't know me well enough to say what I will do and what I won't do, which is why this plan should work." Lucifer smiled, Sam liked this plan, he was sure of it.

"Dean, you understand you're part of this plan, right? You don't have to worry about being taken over. You also will share your body with Michael but coexist as separate souls inside your body." Lucifer turned to look at Dean. Dean nodded and looked at his brother. It was a bad plan but it was the best one he had heard so far.

"Okay, then. Call Michael." Lucifer said and watched Dean close his eyes in frustration. He may not like the idea but he would go along with it.

"Michael, come to me. I want to say yes now" Dean looked around and saw nothing. They waited , looking around the room. Nothing happened. Dean growled, this plan would never work if Michael did not come. "Michael, if you do not get here right now, I am going to change my mind, I mean it!" He shouted and prayed at the same time. Next thing they knew, a bright angel appeared before them and dimmed until it had taken a semi-human appearance. Lucifer smiled at his brother, who smiled back.

"I assume you heard Luci's plan?" Michael drawled, throwing his brother an exasperated look.

"It's Lucifer, not Luci." Lucifer grumbled, his older brother ignore the words. It was an old argument.

"Yes, we did." The boys nodded.

"and?" Michael asked, looking at his brother as if to say, are we really going to do this? Lucifer nodded and shrugged, it was the best plan he could come up with. Michael didn't say a word but rolled his eyes, his little brother came up with some of the most cockeyed plans he had ever heard but they usually worked so he was willing to go along with it.

"We agreed with him, this should work." Dean said nervously and looked at his brother, seeing if he was changing his mind yet. He didn't mind being smited if that was the case. Sam nodded and the brothers took a steadying breathe then went to stand in front of their assigned angel, looking trustingly into their glowing eyes. The angels smiled back at them.

"Yes, Lucifer. I agree to let you take me as your vessel." Sam said, eyes closed and mouth set into a line.

"Yes, Michael. I agree to let you take me as your vessel." Dean wore a similar expression as his brother, they were twins in that moment.

Lucifer and Michael smiled softly at their vessels and shook their heads. You'd think they were facing a firing squad or something, the two brothers shared a thought sighing. These boys must really think badly of them to think this was that bad of an experience.

Lucifer came up to Sam and stroked his face, smiling, "Beautiful man, I accept." He let go of Nick's body and entered Sam's.

Michael approached Dean and smiled as well. "Brave warrior, I accept as well." He went into Dean and then the deals were done.

The boys collapsed on the floor and the four began to plot.

Xxxxxxxxxxxxxxxxxx

They were now in a white room, a magically created room between both men's minds that allowed the souls to separate and talk as themselves, not as they shared the bodies. In this room, they would be Michael, Lucifer, Sam, Dean. Their souls were themselves here and could talk here together then left together to fight or whatever required both souls, the angelic one and the human one, to do. They could also be in their own heads, but have only one of the souls being dominant, the angelic or the human, they would be able to communicate from angelic soul and human soul, carry on conversations, show images to them that way as if talking to each other as humans do face to face.

At the moment, the souls were plotting a way to stop the apocalypse. They sat a long table in the middle of the room and faced each other. They were having a meeting, each soul with its own chair and opinions to add to the plan.

"Wow, this is so not what I pictured when I agreed to this." Dean grumbled, the room was so bright he had to shield his eyes. Sam was doing the same thing, the light was blinding in here.

Michael rolled his eyes and looked at his brother. "Lucifer, turn down the light, would you? You're blinding them." Lucifer looked embarrassed as he had not realized he was shining that much and turned it down to where he did not glow but tried to be dimmer, it did not help at all, he was still too bright. 'Angel of Light' Michael muttered at his brother and gave a long suffering sigh. Lucifer smiled at his brother's annoyance, amused.

The boys wished for dark shades to help make it easier for them to see and they magically appeared on their faces, shielding their eyes. That felt much better.

"So, what do we do now?" Dean asked, Michael laughed.

Sam just scowled, "Come on, the apocalypse is here. Let's do this thing sometime today."

The angels sighed, they were so impatient.

"Well, first thing we have to do is stop the weather changes and release the horsemen from their raids on the Earth." Lucifer stated and Michael nodded.

"I got this one." Michael said and then him and Dean disappeared for a few moments then popped back in. "Done." Michael said sitting down and Dean followed his lead.

"Death said thanks and to leave him out of it next time." Dean smirked, remembering Death's face when they had appeared before him. "He's mad at you. Best avoid him for a while." Pestilence had tried to make Dean sick not realizing he wasn't really himself anymore. Michael had enjoyed that smiting, Dean remember fondly. War was pissed but obeyed when Michael showed up and told him to cease and return to where he came from. Famine had hissed at him from his wheelchair and tried to suck him into himself. Dean shot angelic rays into the guy's mouth instead and he had exploded, he had enjoyed that too.

"So, what now?" Michael asked, Lucifer's plan, Lucifer's rules.

"We lay low and wait." Lucifer sighed, "We need somewhere to hide. The others aren't going to like this."

"I don't really care what they think. Zachariah thinks he can tell me what I am supposed to do and that I have to follow his plan." Dean grumbled and growled. Sam agreed whole heartedly with his brother on this one.

" No matter, it is imperative that they not figure out our plan until it is time. They will interfere." Michael said authoritatively.

"Fine." Sam huffed, and then brightened, "I know where we should go." They all looked at him puzzled. Dean figured it out before the others did, and groaned. It was a good idea; he just hoped they didn't scare the poor guy to death.

"I will drive the Impala there." Dean said, and gave them a look that said that this was what they were going to do and that was it. Lucifer chuckled to himself, Dean really was Michael's mirror image, his perfect vessel.

"Okay, I still don't see why we can't just pop over there. We have the power to now." Michael glowered at his vessel.

"One, it will scare the poor man to death. Two, I don't 'pop' anywhere, I drive there in my baby." Dean grinned. The others all mentally agreed that he was in love with his car, and it was a sick thing to observe. Dean continued smiling, he didn't care what they thought. Besides, he was not in love with his car, he just really really liked her.

The Impala roared into the salvage yard shortly thereafter and the boys sat in the car afraid to go in. Bobby was going to freak. They had only told him they were coming and they had found a way to stop the apocalypse, but they would tell him in person. Both boys knew this plan had to be explained in person, he did not know what they had done yet and he may not understand.

They groaned as Michael and Lucifer got tired of sitting there and took control of the bodies they were in. The boys watched on in indignation as the angels moved their limbs and approached the house. They begged the angels to let them be in charge as they knocked on the door, they had to explain this to Bobby themselves. The angels smiled smugly at them but let them take back control.

"Hi, Bobby." They said unison, nervous and uncertain. Bobby hugged them and let them come in. He had been worried about them. They walked into the study and sat down. Bobby went behind his desk and sipped his beer. The boys went to the kitchen and got one for themselves and went back in.

"So how do you idjits think you're going to get around saying yes to Lucifer and Michael? You do know that is the first hurdle. Those other angels ain't going to leave you alone until you do." Bobby asked, he didn't see a way out of that yet.

"About that…" the boys looked at each other and then gulped. They looked up at Bobby and gave him weak smiles.

"Yeah?" Bobby asked suddenly suspicious, he was beginning to smell a rat here.

"We already did that part." Sam blurted out. Dean threw him a shocked look and mouthed, 'Sammy, did you have to put it that way?' Sam ignored him and smiled. Dean looked at Bobby imploring, begging him not to freak out.

"You what?" He thundered, suddenly pissed. Stupid idjits! Then he had a thought as he glared from one boy to another and sat back down with a thud into his chair again. "You mean , they are possessing you right now? They are here right now? You are them, right at this moment?" he asked softly, he was confused, they didn't seem different to him.

"Yes, sorta. We are in charge right now but they are in here." Sam pleaded, "Don't worry, Bobby, we have a plan."

"They have a plan." He muttered into his beer, "Yeah that will end well." He had no clue what to do or say at the moment so he chose to say nothing.

"Yes, we do." Michael and Lucifer pressed to the surface, speaking through their vessel's mouths, Sam and Dean looking on knowing maybe Bobby may listen to the angels over them.

"Oh, it's you two." Bobby said weakly trying to hide his fear. The angels were speaking to him and smiling. He had no idea how to respond to them.

"Yes, it's us. We don't want to fight and we damn sure don't want to kill each other because some of our brothers and sisters miss Daddy and want to start a war so they can get back at him for leaving in the first place. They are throwing a tantrum and we don't want any part of it. We don't want any more people to die or to see the world destroyed." Michael explained as best he could.

"So why not tell them that?" Bobby asked.

"Because they won't listen. I have tried." Michael said sadly, the others had been most unreceptive to his pleas that this was not what their father would want. They didn't care, it was what they wanted and felt should happen, so he had been forced to come up with plan B.

"Okay, I'll bite. What do you think we should do now? Because if you haven't noticed, it's still the apocalypse out there." Bobby nodded out the window. The angels were on their side, so he was willing to give them a chance.

"We are trying to stop it. We just have to wait until the proper time and place are destined." Lucifer smiled, he liked this guy, he wasn't freaking out badly at all, tough old coot.

"When will you know this?" Bobby asked.

"Soon as the prophet does and writes it down." Lucifer stated as if it was the most obvious thing.

"Prophet, as in Chuck the writer?" Bobby gulped again, this was a weird visit.

"Exactly. We find out the where and when and show up at that place and time then go there. We can stop it from there." Michael explained. Sam and Dean smiled, Bobby was taking it well.

"So what do you need from me?" Bobby asked wondering why angels had come to him now.

"A place to lay low, Bobby." Dean said, Michael receded to the background so he could talk to Bobby. "We can ward this place so they can't see in and find us, the angels will help."

"I hate to risk smiting here but I have to ask." Bobby eyed his boys, suddenly worried, "What happens after, are the boys released from vessel duty or what?"

The angels looked sadly at the boys and the boys nodded. This was the part they had been dreading, Bobby may not like this part.

"We can't ever be released. We will be joined with them until the end of time. They will stay inside us. We are immortal now." Sam said sadly, "This is permanent." He looked to Dean for help, Bobby didn't look so good.

"We'll still be us, we'll just be them, too." Dead added quickly, "Please don't hate us, please don't turn us away. We will always need you, angel possessed or not." His eyes pleaded with Bobby.

"We need you to trust us on this." Sam pleaded as well, "Afterward, if you don't want us around anymore, you never have to see us again or even hear from us again. All we'll ask is you don't tell anyone about what we really are, others will not understand." The boys looked down at their hands and wanted to cry at the thought of losing Bobby in their lives but knew they had made their decisions when they had said yes. It was too late to change it now.

"Don't be stupid, ya idjits. Angel vessels or not, you are still my boys and I will always want you around like I always have. Besides, this way, I don't have to worry about you getting hurt too much on hunts anymore." Bobby smiled, the boys looked relieved. "So this vessel thing, does it come with benefits?" He had to know.

"Super strength, well angelic strength, at least. Faster healing abilities. Enhanced battle skills, that's about it." Sam said as Lucifer provided the details. Bobby nodded, he had hoped for that.

"We have wings like the other angels do now. You just can't see them with human eyes, but they are there." Michael smiled.

Sam and Dean nodded to Bobby and he just shook his head. "Never thought you boys would ever have wings either. " Bobby grumbled good-naturedly. The boys seemed to have the situation in hand, he didn't have to worry so much. Besides, they had two other angels to watch over them now.

He went to the kitchen and began to get ready to make supper. The boys' stomachs made a noise, they were hungry. Michael and Lucifer just sat back and let their vessels get a bite to eat, they had earned it. Shortly later, the boys went to bed and the angels sat in their meeting space they had created so they all could talk earlier. They discussed the rest of the plan and agreed that it could work.

Xxxxxxxxxxxxxxx

The group of four men sat in the graveyard, watching the clock. Well, three angels and a human. Castiel had been a little shocked when he had felt Lucifer and Michael inside his friends, Zachariah and then had made it sound as if the boys would be tossed aside once they said yes but it was turning out that was not the case. Now the angels were talking about helping the Winchesters stop the apocalypse. His world was in chaos, he was confused at what he was supposed to do now. He supposed he could play his part in the plan, protect Bobby.

The time came and the angels stepped out of the car and shut the doors. They walked to the middle of the field and stood there looking at each other, waiting for the last part of their plan to kick in. They hoped this would work, they all did not want to kill their brothers.

They all came with a whirlwind of feathers flapping and soft steps as they landed around the pair, their eyes calm and their attention on the impending battle. Zachariah stood smirking, like he had orchestrated all of this and it was working out the way he had wanted it to.

Dean had to fight the urge to smite the smirking angel on sight, Michael soothed him and promised that would come later. Dean quieted but glared inwardly at the angel and waited for his time to come. They didn't have to wait too long. The moment time struck, the angels, Michael and Lucifer, felt the power of it envelope them and pull them into action.

Lucifer tossed the rings to the ground and chanted. Michael turned to face the angels around them. The cage opened and the angels looked on in shock.

"We are not doing this." Michael commanded, his power pouring over them.

"We are not killing each other for your apocalypse." Lucifer announced with his brother, "This ends now." Both of them put away their weapons and stood there, waiting to see what their brothers and sisters decided. Most of them looked relieved or calm then flew off back to Heaven. One angel remained.

He sputtered on, mouth working like a fish stranded out of water. His eyes angry and hateful.
"No! this is not the way it was supposed to be. This is not the way the apocalypse was supposed to come about!" He shouted at the calm and composed angels before him, neither moving to kill the other or to approach each other.

"We don't care how you meant the apocalypse to be." Michael stepped toward the angry angel, "This was never our true apocalypse. It was yours, you were pissed Father left and never came back, so you decided to destroy his greatest creation to punish him for that."

"How can you know that? He wants this or he would have stopped this already." Zachariah hissed.

"Because he told me so himself. He didn't want this. That is why we are not doing what you had in mind." Michael assured him. Dean saw this was true, his father had talked sense into the avenging angel and made him see that this apocalypse was not going to be allowed, which is why he had approached Lucifer in the first place, to make a plan on how to achieve his father's wishes.

"You lie. Father is gone or dead. He is never coming back. You didn't do this, you lie!" Zachariah shouted hatefully at Michael, the boys could feel the righteous anger coming to the surface in Michael but said nothing, Michael would not tolerate insult to his father.

"You are close to blaspheming, Zachariah. Be still and say no more." Michael warned, his eyes/Dean's eyes burning green fire.

"No, I will not listen to you anymore. I do not blaspheme. Don't you get it, Dad doesn't care, we are in charge now. Heaven is ours, it's been ours for centuries. " Zachariah continued, not sensing the danger he was in, "God doesn't care what we do now!" he shouted, Michael was wrong, he was right.

"I warned you." Michael sighed and then reached into Zachariah's chest and pulled out his Grace. Then both Sam and Dean took control of their bodies and smiled at the man, who stood screaming in agony as his Grace was ripped out. Once Michael was done, they shoved him hard into the hole and locked the cage behind him. Zachariah screamed the whole way down and it made the boys smiled wider

They waited as Michael carried Zachariah's Grace back to Heaven and locked it away. When he returned, they got in the car and drove back to Bobby's, happy they had finally stopped the apocalypse and saved the world.

"So, what now, boys?" Bobby asked the smiling boys, their expression now taking on the characteristics of both the angel within them and the boys own features as well. The changes were imperceptible; The only reason Bobby could tell is he knew them so well. Their skin was also gradually becoming lighter, becoming slightly angelic like Castiel's. Their eyes held a small glow now, barely more than a shimmer over the pupil and iris. Their eyes were now both forest green, like Dean's was but with a blue circle around the pupil, like Sam's. When the angels were in control, their pupils became pools of bright light contained within them. They were bulkier and more muscular, they were more agile and stronger now, stronger than Castiel even.

They were still themselves but they were also the angels too. Bobby found that he was okay with that, the boys were good with it made it okay with him.

"Well, "Michael and Lucifer were in charge at the moment, their eyes glowed a bit. "We were thinking of this 'hunting' that the boys do, that we do now, I guess."

"We were thinking we would give it a try." Lucifer grinned devilishly at the thought of 'hunting' with Sam. Michael broke out in a wide grin that was pure Dean and looked at his brother then at Bobby. Sam and Dean clapped them on the back internally and were excited about it too. They all wanted to do this and the boys swore to help them get into it right and proper. The angels would be good at it, they were naturals to it, being warriors of God and all.

Bobby burst out laughing and finally had to force himself to stop." I'd better find you a hunt then." He gasped out and just looked at the smiling pair in front of him, their eyes becoming a mixture of bright light and forest green. They all were looking at Bobby now, Sam in Lucifer, Dean in Michael. He reached for some files and began to check them out.

He felt bad for the supernatural baddies. You really shouldn't mess with angel power, let alone angel-powered hunters. This was going to get interesting, so very interesting.

Xxxxxxxxxxxxxxxxx

(Sam and Dean may be angel possessed but they are taking it in stride, turns out Michael and Lucifer aren't so bad after all. Who knew? I got to feel a little bad for Zachariah though. He never did have the sense to know when to shut up.

Please read and review. Please let me know if you want me to make this a longer storyline or a one shot. I am unsure at the moment how I want to work on this one.)
