🚨Important🚨

(Before we start, just wanted to say that this chapter has a crossover with a Netflix serie 'Lucifer'. I started to see this serie with my dad and then this idea appeared in my head so deal with it :) )(There is no spoliers about the serie or something like that, althought there is gonna have a little twist or something)

(Also, this is a long chapter, like, longer than the usual)

"Y/N! Wake up!" Peter and Harley shook me awake and practically screamed at my ears. They were still in their pj's and their hair was messy, probably they woke up now too.

"What time is it?" I said with one eye open and my morning voice.

"Doesn't matter! Dad isn't here! He's not even in the tower!" They screamed. I immediatly got up and regret it the moment I did because I was now dizzy.

"WHAT?! No no no no, people are gonna see him, they're gonna speak to other people, and the media will find out! Fuck!" I started to freak out. I honestly think I'm gonna have a panic attack, like, NO ONE can know about this. "Did he leave somthing? Like a note? What time is it, god damn?" Maybe I'm freaking out to much, maybe not.

"Boss left a note beside the elevator when he left and it's currently 11:00 am." FRIDAY spoke up. 11:00 am?! Why didn't my alarm woke me up? I looked at where my alarm clock is supposed to be and he is indeed there, but destroyed, okay... I stormed out of my room and went to find the note beside the elevator, my brothers followed me confused but then understood that I was going to find and read the note. When I reached the elevator, I found the note on the little table that we have beside it, I don't know why we have it, and in it was writted:

Sorry sweetheart, but I had to go, you weren't in bed either so I just left this note.

Had lots of fun last night.

-T.S.

"Okay, he thinks he had a one night stand, so he's probably in his years of playboy now, which mean that he's an adult now. He could be anywhere then, but he said that he was going to work, so he probably headed to Stark Industries, but knowing him, probably not. Peter, go spidermaning around the north of the city to see if you can find him or just a lead. Harley, take Happy with you and try to find him by car in the south. I will walk on the streets and stay in the center. Got it?" They nooded and Peter went to his and Harley's room to get the suit and jump out of the window to go spidermaning. Me and my twin went to change first and then got in the elevator and went to the lobby, where Happy was.

"Happy!" Happy turned around from where he was and signaled for us to slow down.

"No running. You know the rules." He said with his usual annoyed face, but with a little smirk.

"Doesn't matter that right now. Dad's gone! He isn't at the tower! Peter went to look for him in the north of New York, I need you to take me by car to the south so we can look for him there, and Y/n will walk in the center." Harley said in a hurry while trying to take Happy to the elevator to go to the garage. I waved at them and went running out the door.

Where would a genius billioanire playboy philanthropist go? A party? No, it's to early for that. Work? As I said before, not Tony Stark. He can- Oh shit! I have an idea! "FRIDAY, show me the footage of dad leaving the tower and the path that he did." Why didn't I thought of that first? Because I was freaking out, I guess.

FRIDAY put the camera footage in the sunglasses that I was using and I stopped in my tracks to see, of course that I wasn't going to stand in the middle of the street, so I went to an alley that was almost beside me. There I saw dad leaving the tower with a suit, no it wasn't an iron man suit if your confused, probably on of the suits that was on the closet, and then he went to the same path that I was doing, yey. I started making the same path that he did and when 'we' stopped, 'we' were in front of a bar. Seriously? At this hour? "FRIDAY, what hour did he enter? And, has he got out of here?"

"Boss was here at 9:30 am. He left at 11:00 am, the exactly hour you woke up." FRIDAY said to me, showing the footages of dad leaving the bar and the hours.

"Okay FRI, lead the-*boom*" Suddenly I'm on the floor and my glasses aren't on my face, I search for them and when I found them, I reached out my hand to grab them but someone grabbed them first. I looked up to see a tall, dark haired guy, looking to be in their teenage years, like me. He handed me my glasses and smiled, I took them and put them in my face and then grabbed his hand that he still had stretched in my direction to help me get up. "Thanks."

"You're very welcome." The guy seems to be british due to his accent. I kind of like those accents, like, when they say 'bloody hell', I don't know, I'm weird. "What's your name, mysterious girl?"

"I'm Y/n Stark-Barnes." I said to the boy and he made a 'o' expression with his face.

"So your the daughter of the man that escaped death with a battery car in his chest!" He exclaimed and I was honestly offended by that. Like, the dude just said that about my dad, who does he think he is?

"I'm sorry, but who are you to be saying those things about my dad?" I angrily said to him. He looked surprised by what I said.

"I'm Lucifer Morningstar, the devil himself." He smirks and puts his hand out to me to shake, which I do.

"So, you're one of those people that pretend to be other people just to be cool? Like, seriously, the devil?" I asked him confused, totally forgetting that I need to find dad. He looked confused too and a little surprised.

"No, of course not! Why would I do-" He got interruped by two human beings behind him shouting his name, he looked at them and smiled. While he looked away, I examined him, he is tall, like I said, he has fancy clothes, like a suit, and fancy shoes. Why would a teenager dress like that. "Ah! Chloe! Detective Douche!"

"Lucifer! You can't disapear like that! We were worried!" Chloe, I assumed, exclaimed with sings of worry and relief in her face.

"Chloe, you sound like worried parents talking to their child." Detective Douche said. What kind of name is that, like, I'm really confused.

"Yeah yeah. Chloe, Dan, this is Y/n. Y/n, this is Chloe and Dan. Where's Maze and Amenadiel?" He looked around trying to find this Maze and Amenadiel persons while me, Dan and Chloe waved at each other with little smiles.

"They went off somewhere. Let's go Lucifer, I'm sure Y/n has other things to do." Chloe said and then I remembered, I need to find dad! That's the reason I'm outside!

"I need to go now! It was nice meeting you all but I really need to go now!" I quickly said and started to walk away.

"Wait! I'll go with you! See you later people!" Lucifer said. Why is he coming with me? I just met him. Is he like that with most people? "So, what are we looking for? Is it something important?"

"What? How do you know I'm looking for something? Why did you came with me in the first place?" I asked him confused. FRIDAY was giving me the directions to where dad went. I'm seriously hoping that it's not an apartment or something like that, like, for fuck's sake, it's 11:50 am dad, you're not supposed to be doing this kind of things at this hours.

"Well, you're looking everywhere so I assumed you were looking for something, or someone. I came with you because, why not? You just live once, and you seemed to need help." Lucifer said. Is he crazy? For all he knows, I could be leading him to a trap or something.

"Okay, that makes sense. But yeah, I'm looking for someone. A very important someone. I guess you can tag along with me, but I really don't need help, I already have my brothers help. They are looking on other places in New York. You-" Why's there something always cutting us off? Anyway, Peter was calling and I answered in my earpiece. "Hey Pete, you found him?"

"No, I just wanted to check with you. I already called Harley and he said that he hasn't found dad yet and he has been almost everywhere. By the way, I found Wade so he is helping me trying to find dad." Peter said while probably swinging by the buildings where he was.

"I found company too. His name is Lucifer, I'll tell you guys later. By the way, I remembered that we could have just asked FRIDAY to tell us where he is, but don't worry, I'm already on it. Bye-bye." I said and hang up the call before he speaks again because then he's just gonna ask question and I prefer to hear it later. "So, how old are you? Why did you call Dan, I think it's his name, 'Detective Douche'?"

"I'm seventeen, almost eighteen, and before you ask anymore questions, I'm gonna answer them all. Dan and Chloe are my friends, Maze is also my friend and Amenadiel is my brother. I call him that because he wants to be a detective in the future and he's a douche." He smiled at me and continued to walk with me to where dad is which is an unknown place for now. "Now it's my turn. How old are you? Is this Peter guy one of your brothers? Who are you looking for?"

"I'm sixteen and yes, Peter is one of my brothers. My other brother is Harley, my twin. And the person I'm looking for is... You're gonna find it weird, I'm not gonna say it." I told him, shaking my head.

"Oh come on, I'm the Devil, what is more weird than that?" Okay, he really thinks that he is the Devil, hm?

"I'm looking for my dad..." I said, looking straight ahead of me and not to his face, he is probably thinking that he should never have joined me and that I might be crazy, which isn't totally false.

"Isn't it supposed to be the other way around? Like, your father be looking for you and not you for him? And why?" That surprised me, he doesn't seem to be thinking what I thought he would be thinking.

"Don't tell anybody, okay?" He nooded and then I explained to him what happened. From time to time he would laugh or just nood or be confused, I'll have to admit, it's kind of great to talk with someone that doesn't have a clue what's going on in your life, about what's happening.

"Bloody hell. That's amazing and confusing." He exclaimed. There it is, the 'bloody hell' that I love hearing just because of the accent and because I find it funny, I don't know why. The rest of the way, we just talked a bit more, getting to know each other and eveything. When we arrived at the place that dad was supposed to be, he was about to leave that exact place,so you could say that we got here in time.

"Tony! Wait!" I screamed, running up to him with Lucifer behind me, as he turned to look at us, confused.

"Excuse me but who are you?" Dad asked us with a coffee in his hand. Where did the coffee appear from? Oh well, it doesn't matter now.

"I'm Y/n and this is Lucifer. You have to come with us for the day. I promise you, it's just today." I smiled at him but he still looked suspicious. "Just trust me, please." He nooded slowly and came closer to me because we were still a few meters apart. "How old are you now? Just so I know."

"I'm 22 years old and you look to be around fourteen and he looks like fifteen. Am I getting kidnapped? By teenagers?" He asked, a bit confused, looking me and Lucifer up and down. So, if dad is already 22, the accident already happened and it's kind of the reason he is like this now. Drinking and one night stands.

"Does this looks like a kidnapping? And I'm actually seventeen and she's sixteen." Lucifer said, standing beside me.

"Well seen. Do you have a car?" Dad asked. I was already one step ahead of them and had already texted Harley to come pick us up, then I texted Peter saying that he could go to the tower and change to normal clothes that me and Harley were on our way there.

"The ride should be here any minute now." I informed the two guys that are with me and they nooded. We waited five to ten minutes before Happy and Harley got here and when we entered the car, the two of them gave Lucifer strange looks. Guess we should drop him off now. "Lucifer, where should we drop you off?"

"Well, I was thinking of staying with you for a bit more because this has been fun. But if you don't want me to stay, it's okay." He said with a hopefull look in his eyes.

"For me, you can stay, you're cool. But I don't know if Harls there or Peter are okay with it. Do you mind?" I asked Harley and he shrugged. "Wait. What about Chloe, Maze, Amenadiel and Detective Douche? Wouldn't they be worried about you?"

"Nah. They're fine, they know I'm with you, well I don't know if Maze and Amenadiel know but Chloe will tell them. It's totally fine." Lucifer said and then stared out of the window. The rest of the trip to the tower, which took, more or less, 20 minutes, nobody talked much, we mainly just listened to the music that was playing on the radio. When we arrived, the questions started, well, kind of.

"This was the place that I left this morning. Why am I back here?" Dad asked, having no clue what was going on.

"Well, you weren't supposed to leave the tower today, so your back. Tomorrow you will be back to your normal life." Harley spoke up when we were entering the tower to go to the elevator so we could go to the living room and relax, Happy would stay down here to do his job. When we finally reached the living room, Peter was in the couch, watching TV. Wade probably had something to do and couldn't come.

"Hey Pete." My twin and I said at the same time and then we high-fived each other. Peter looked away from the TV and at first he was confused with dad and Lucifer, but then his mind remembered that dad isn't still back to normal and I had found company in my search for dad.

"Hey guys. You must be Lucifer, and you Tony. I'm Peter, Y/n and Harley's brother." Peter got up from the couch and came towards us to greet us properly with a simle and shake of hands. We went to the couches and sat down for a while, just seeing random things that were on the TV and when we were all hungry, we decided on ordering chimichangas.

After we ate the chimichagas, they were delicious by the way, we saw a movie like usual. The movie that we saw is one of my favorites, 'Top Gun'. It was amazing like always and Tom Cruise, my god (I'm sorry, but it's true. The things about the movie are my personal opinion. If you want, you can change the movie that you saw). After that, Peter and Harley decided to go to the lab, so they went there and took dad too. I decided to just chill in the living room and since Lucifer was here, play a game with him. Before I could do or say anything, in front of me appeared a hologram saying 'pops is calling'. I kind of shoved Lucifer out of the couch before FRIDAY answered the call. "What in the blo-" Before he could say anything else, I threw a pillow at him and made a 'sush' noise.

"Hey pops! What's up?" I said with my voice an octave up, I don't know why.

"Hey..." He looked at me with suspicion before he continued. "What's wrong? Your voice is high and you look weird. We're good by the way, we finished the mission now, we'll be back tomorrow morning probably."

"That's great! Sorry for not calling yesterday, we went to school and we forgot, sorry. But yeah, it went great! Today dad is 22 years old. We already had an adventuare." I rubbed the back of my neck because I don't know what to do and I just want to change the subject matter because they would probably freak out if they saw Lucifer here, a totally stranger to them, that I met today.

"What happen?" Uncle Rhodey asked, probably concerned with our little adventure.

"Well, we were going to school today and leave dad here, with FRIDAY and all, but that didn't happen. First, my alarm didn't wake me up because it was smashed, I don't know how or why, and then Peter and Harley woke me up at 11:00 am saying that dad disappeared. He left a note saying that 'he had fun last night' and things like that, basically he thought that he had an one night stand, so then, Peter went to look at the north of New York, Harley went with Happy to the south and I stayed in the center. After a bit, I found him, thanks to FRIDAY and the security cameras, and then we came home." I explained everything to them, everyone in the quinjet had joined the call so they could hear the story.

"Okay. But your all good, right?" Uncle Scott asked and I nooded with a small smile. Then Lucifer got off the floor and sat by my side, my eyes widened. Fuck.

"And they met me." Lucifer said with his smile.

"How's that?" Pops said with a dangerous look and I shoved Lucifer off of the couch immediatly and spoke quickly.

"No one! Bye!" I ended the call right away and looked at the 'Devil'. "You weren't supposed to do that! Now they're gonna be paranoid! FRIDAY ignore the calls that the avengers that are in the quinjet are gonna make until they're here." I exclaim and he is not even a bit affected.

"You need to relax. Tell me, what do you desire to do with the rest of your life?" Lucifer gave me a look that could hypnotise anyone but not me, I'm stonger than that, I'm going to pretend instead. I looked at him a look of someone that would fall for this and spoke.

"I... I want to be like my dad and pops. They inspier me to be better." I continued and he smirked, but then I dropped the act and spoke normaly with a bored expression. "And I want to eat ice cream too."

"Wait what? You were pretending." He looked shocked and, kind of, concerned. Why?

"What? Don't tell me that that works on people and you actually get to know what they desire?" He looked at me with worried and I was shocked. "Wait what? Why doesn't it work with me?"

"I don't know..." He got up and started to go to the window. "I'm just gonna make a call." After he made the call, he came back to the couch and sat down in silence. An awkward silence.

"Do you wanna go to the lab? See what they are making. Be with them." He just got up and started to walk to the elevator, so I took that as a 'yes'. I went after him and we got into the elevator, went to the lab and stayed there.

When it was time for dinner, we did the usual, call some place and order something. It was pizza again. Lucifer stayed here with us for dinner and the movie. During dinner, we decided that tomorrow, we wouldn't go to school again and just start going the next week, regardless tomorrow is friday so it really doesn't matter.

When it was time for the movie, we decided on watching 'Edward Scissorhands', I honestly haven't watched that movie in ages so it was good to see it again. After that, we must have been to tired to stay awake because we ended up sleeping on the couches. Peter and Harley in one couch, dad on a bean bag and Lucifer and I in another couch.

Heyyy guyssss, so sorry for the wait, it was because I didn't have ideas as I said, but now you ended up with a bigger chapter.

The chapters of these story usually have between 2100 and 2500/2600 and today you have...

3685 words

WHAT?!

But yeah, I think I'm gonna put the number of words in the end of chapters, I see a lot of people doing it, so why not?

I hope you liked this crossover with Lucifer. He's probably gonna appear in the next chapter, Idk, I still haven't writted it.

Stay safe!

Peace off my dudes

Love ya
