Wolfie: I do not own anything related to Supernatural or Lucifer, just this AU. I was inspired by other Lucifer/Supernatural crossovers, it will start at the beginning of Lucifer season 1 and during Supernatural season 4. I'm sorry if Maze and Dan seem out of character but it works well with my story. Lastly this is a Fem Lucifer AU, and if you want this to be a romance fic then just let me know! Now please read, review, and I hope you like the book so far.

Chapter 1

Dan sighed slightly in annoyance as he left the club, pinching the bridge of his nose. He thought this would be an easy case, where all he needed to do was look into the death of the singer Delilah. And then the only witness to the killing threw the LAPD detective quite the curve ball. He could still remember talking to the raven haired woman who ow me the club the shooting happened infront of. She claimed to be Lucifer, but that wasn't the weirdest part. Despite the fact that she had been there during the shooting she was fine whilst Delilah was riddled with bullets. And when he asked her how she survived she claimed to be immortal, and he knew that this was out of his league. Fishing his phone from his pocket he dialed a number he never thought he'd have to call again. The phone rang once, twice, thrice before the call was finally picked up by the owner of the phone on the other side of the call.

"Hello?" Bobby asked as he answered his phone, holding it between his shoulder and ear as he opened a large, thick, dusty looking book.

"Hey Bobby, it's Dan." Dan stated as he climbed into his car and didn't do anything else but shut the door behind himself.

"Dan, haven't heard from you since-." Bobby started to say whilst flipping through the book he had just opened moments ago.

"Since that werewolf you helped me with a while back." Dan finished, reminiscing about that fateful event as it was still fresh in his mind.

"Right. So what'd you call about, Dan?" Bobby asked curiously as he left the one book open and then opened another one.

"I think I got something that's right up your alley. I'm working a case about a shooting, and the witness claims to be immortal. I'd normally brush this off as trauma or insanity, but she says she's Lucifer." Dan said, remembering how Bobby had informed him about the apocalypse.

"Huh, well I'll put my best men on it Dan." Bobby said as he knew just who to call.

"Thanks Bobby." Dan said with a sigh of relief.

Meanwhile driving down a back road was a loan black 67 Impala. Sam sitting in the passenger seat like usual as Dean sat behind the wheel driving. The younger of the two immediately fished out his phone when it started ringing and answered it when he saw it was Bobby. Putting the call on speaker phone so that Dean will be able to hear it and talk to their father figure too. Sam and him sharing a glance for a moment as they hoped that this call was news about Lucifer and the apocalypse. Though they certainly got more than they hoped for when Bobby told them about Dan and this so-called female Lucifer. Dean didn't need to hear anything else after Lucifer was in LA as he jerked the wheel to the right, making the car do an illegal u-turn. Sam nearly dropped the phone in response to this, telling Bobby he'd call him back later. He could understand why Dean was in such a rush to get them to LA to get the full story from the Dan guy Bobby mentioned though.

After all this was their chance to get the drop on Lucifer, but there was just something that wasn't sitting well with the younger Winchester. If this truly was the archangel they were after it was honestly odd. They hadn't known that Lucifer had found a willing vessel yet, let alone a female one. And she's just, minding her own business and being a witness to a shooting? It just didn't make any sense to Sam, after all Lucifer is free now! Shouldn't she be trying to take over the world or something? Dean honestly wondered the same things that Sam was wondering about Lucifer. But the elder Winchester was mostly worried about the vessel that currently held the archangel. Had the girl really wanted to let Lucifer in, or had she been tricked like the last guy Lucifer was wearing? And what happens when they get there to try and stop the archangel? Will she be left burnt out and dead or will they get there in time to save her? Dean hoped that it was the later, no one else should die because of that archangel bastard.

No more than 12 hours later after a long drive to LA and one conversation with Dan Espinoza later an 67 Impala pulled up to the club Lux. Sam and Dean stepping out of the car almost in unison, rocking a set of suits today. Approaching Lux's bouncer they flashed him their FBI badges, immediately being allowed in seconds later. For a place that had opened a half hour ago it was already bustling with club goers. Just hoards of people drinking or dancing to the loud music that was thumping throughout the club. Bartenders and servers worked without batting an eye at the masses, but there was one person who stood out from the rest. Sitting in the middle of a circular booth, drink in hand was the woman that Dan had told them about, Lucifer Morningstar. She sat there in the booth in a long sleeve off the shoulder A-line high split dress. One leg crossed over the other and a smirk on her equally blood red lips as she seemed to be holding a conversation with a male club goer. Though the conversation fell silent when Sam and Dean approached the two occupants of the booth.

"Miss. Morningstar?" Sam asked politely, causing Lucifer to turn her gaze towards him curiously.

"Depends on who's asking." Lucifer stated with a Cheshire cat smirk on her painted red lips.

"Agent's Angus and Young." Dean said as him and Sam flash Lucifer their FBI badges before putting them back in the inside pockets of their jackets. "We'd like to talk to you about the death of Delilah." He said causing the devil in disguise to frown, clearly not liking how casual he was about that topic.

"...We will continue this business transaction at a later time." Lucifer said as she looked at the male next to her who looked about ready to protest. "For now, go and speak to Maze." She said before the male could argue with her as he nodded slowly, leaving the booth in search of said person. "Now, how do you know about Delilah?" Lucifer asked with an arched eyebrow, all business all of a sudden as she motioned for the two to sit down.

"The crime was brought to our department's attention by a Detective Espinoza." Dean explained, seemingly professional as he accepted the offer to sit down as Sam did the same.

"We wish to further shine light on this situation Miss. Morningstar, and we were informed of your statement to Detective Espinoza's fellow Detective, Chloe Decker." Sam said as Lucifer glanced at him, her head tilting to the side slightly as she watched him.

"I see, then you should know that the man who shot her was just a hired gun. He wasn't who truly wanted Delilah dead." Lucifer said as she took a sip from her so far untouched drink, leaving a blood red lipstick mark behind on the rim of the glass.

"And why should the FBI believe this statement to be true, Miss?" Dean asked, trying to be polite despite wanting to just end this so-called Lucifer here and now.

"Because I never lie, I despise liars." Lucifer stated as she looked Dean directly in the eyes. "Which is why I must say, it's very bold for you to lie directly to my face, young hunters." She said as she then looked at Sam, both men stiffening as her eyes glowed red.

"...How long have you known?" Sam asked hesitantly as Lucifer's eyes faded back to their natural dark brown.

"Since you walked through the door." Lucifer stated as she placed her glass down on the table.

"Then why haven't you killed us if you know what we are?" Dean asked, his gruff demanding tone causing Lucifer to chuckle.

"Because your curious, are you not?" Lucifer questioned, smirking again as she got her answer when neither Winchester argued with her. "You're wondering why I'm here in LA, in a club, rather than doing what your bible has foretold." She continued as Sam and Dean glanced at one another.

"I'm wondering a lot of things. Like since when are you British? And a chick?" Dean asked, feeling bold enough to say such things since Lucifer hasn't tried to kill them.

"What, is this form not what you truly desired to see me as?" Lucifer asked as she leaned closer to Dean, working her mojo on him immediately.

"No, no this is, definitely an improvement over the other body you snatched up." Dean admitted with a flirtatious smile, only to be shocked at what he had said.

"The, other body?" Lucifer repeated to herself, confused as to what Dean had meant.

"How are you here, Lucifer? Last we saw you were in Carthage, summoning Death." Sam said causing Lucifer to look back towards him again.

"The horsemen, Death? Why would I want to summon that old stick in the mud?" Lucifer asked only to have her eyes widen in realization. "Bloody hell, that thing actually got released?" She asked as her question confused Sam and Dean greatly.

"That thing?" Dean repeated, brows furrowing in confusion.

"Then that you in Carthage, wasn't you?" Sam asked, wondering if that assumption was correct or not.

"Of course not. Do you honestly believe I would want to participate in the bloody apocalypse when I have all of this? I have money, liquor, a penthouse all to myself. I have men and women alike just dying to fulfill their truest desires with me. It's my own paradise on earth." Lucifer said, she liked it here too much to have some apocalypse screw things up for her.

"If that wasn't you then why did he say he was?" Dean asked, there was no way there could be two Lucifer's, could there?

"...I think we are done with this conversation, gentlemen." Lucifer said rather than answering Dean's question.

"No we are not done with this conversation." Dean said, he did not come all this way just to not get answers.

"I said we're done here!" Lucifer snapped, her eyes glowing red again as her snapping gained the attention of her faithful demon companion.

"Everything ok here Lucifer?" Maze asked as she approached the booth, demon's weren't ones to be concerned or caring, but she does when it comes to Lucifer.

"Yes Maze, everything is fine. I'm just, tired." Lucifer reassured as Maze looked at the two men who are obviously hunters.

"I suggest you leave her alone, before I have security make you leave." Maze stated as both Sam and Dean caught the distinct smell of sulfur peaking through the smell of sweat, liquor, and massive amounts of perfume/body spray. And them without their holy water...

"We were just leaving anyway." Sam reassured with a smile as he stood up, Dean begrudgingly doing the same. "If you can think of anything else, this is our number and where we'll be staying." He said as he wrote said things down on a business card and tried to hand it to Lucifer, only to have Maze snatch it from him instead. "Ok, we'll see ourselves out now..." Sam said as he walked towards the exit, making sure that Dean was following alongside him.

Lucifer sighed slightly when they were gone as she finished her drink. Putting on a brave face as she continued to perform her usual daily and nightly activities. And when it was all said and done she was up in her penthouse, the club below still thumping with music as it was still open. Having changed out of her dress into more comfortable clothing and had removed her makeup as she stood on her balcony. Looking out at the lights peaking through the darkness of the LA night as she smoked a cigarette. Turning around just in time as the elevator that led up to her home dinged and the door opened to reveal Maze. And she looked none too happy as she approached the devil in disguise. Obviously about to go on a rant of some kind judging by her posture and current body language. Lucifer really wasn't in the mood to hear it but she knew that if she didn't then Maze would take her rage out on some unsuspecting human.

"Lucifer what is going on? Those men were hunter's, why were hunter's here?" Maze asked, obviously mad despite the concerned nature of her questions.

"Maze." Lucifer stated, trying to get the female demon's attention

"They're not here because of us are they? Or did one of the other demons screw up and put them on your trail?" Maze asked, continuing to talk despite the fact that Lucifer was trying to get her attention.

"Maze." Lucifer tried again as she sighed out a puff of smoke.

"Just tell me why they're here and I'll deal with it." Maze said as she cracked her knuckles, clearly itching for a fight.

"Maze, they were here because it is now free of the cage." Lucifer said, effectively cutting off Maze's rant about going back to Hell before it even began.

"What?" Maze asked, wondering if she had heard Lucifer correctly.

"And it has already summoned the four horsemen." Lucifer continued to speak as she finished her last cigarette for the night.

"...So then what's the plan?" Maze asked, after all Lucifer must have made a plan for a situation like this, right?

"Putting that, thing, in a cage was my plan!" Lucifer snapped, this was all just so frustrating. "I thought it would at least buy me a few apocalypse free millennia, not a few years." She said as she stalked past Maze and back into her penthouse, making a b-line for her personal bar.

"So you have no plan then?" Maze asked, wanting to clarify that this is what Lucifer was telling her.

"No Maze, I do not have a plan." Lucifer said as she poured herself a glass of whiskey, giving Maze the clarification she wanted. "...But I know of two hunters that might just have one." She said as she caught sight of the business card that was now abandoned on her kitchen counter.

"No, you'd better not be thinking about what I think you are." Maze said as she caught a glimpse of that all too familiar glimmer in Lucifer's eyes.

"Oh but I am, Maze. I am indeed." Lucifer stated as she took a sip of her drink.

"You can't be serious, Lucifer." Maze said, wishing that the other girl was indeed not serious about this. "They're hunters, you can't trust them." She said, hissing out the word hunters as if it was a bitter taste in her mouth that she had to quickly spit out.

"Who said anything about trust, Maze? I'm just going to make them an offer they cannot refuse." Lucifer said as Maze sighed in frustration, there was no way of talking the devil in disguise out of this now.

"Just, be careful..." Maze said as she gave up trying to argue, for now.

"When am I not?" Lucifer asked with an amused smirk. "Wait, don't answer that." She added a few seconds later once she realized that there was evidence that would contradict what she had just asked.

Maze lightly shook her head at this as she headed back into the elevator and back down to the club below. Lucifer watched her leave as she took a deep breath, her faithful demon companion had every right to be worried. Hunters always seem to see things in black and white when it comes to monsters. So there was almost no chance that they wouldn't do the same with angels. Or in her case a fallen arch angel labeled as the Devil. But Lucifer knew that she would be ok, after all she doubted these boys knew about angel blades, let alone how to kill an arch angel such as herself. With that thought in mind she was confident that she could interact with these hunters without endangering herself. The only thing she has to worry about is other angels though, like her stick in the mud brother Amenadiel. If he saw her consorting with humans, let alone hunters that are trying to stop the apocalypse. Well, he'd certainly have a shit fit and would most definitely attempt to stop her and return her to hell. But he hasn't succeeded so far, and he certainly won't start to succeed now.

Meanwhile in a local LA motel Sam and Dean had changed into their normal clothes and were attempting to regroup. They had just learnt that there are basically two Lucifer's, one is a slowly pealing ass bent on jumping into Sam's body and starting the apocalypse. Whilst the other one is a hot chick that is more concerned with running a club in Los Angeles. Would they have to worry about her joining in on the pro-apocalypse team? Or is there a small chance that this Lucifer could be on their side and that she might just help them? They won't know unless she actually comes and tells them what she is going to do about this. But, judging by her reaction Dean insisting that the conversation wasn't over they might not get to talk to her again. And both brother's were sure that if they tried to force Lucifer into a conversation that demon Maze would be there to stop them. So really they were grasping at straws on what to do right now. But since it was late the two of them decided that it was high time they hit the sack for the night. Assuming that they'd be able to figure this out better with fresh eyes and well rested minds.
