Hey guys it's me and I have a new fanfiction to share with everyone. Okay I know I shouldn't post a new one yet since I have tons of unfinished ones here in the site. But I can't help it. This idea has been bugging me since well... I don't know, maybe October? I just need to put this up here. And after reading tons of HP/Avenger crossover I thought I needed to have a Daddy!TonyandHarry fanfiction. And as always this is a Fem!Harry fanfic.

Note: This story will mostly focus on the MCU and not much on HP verse. So might not see much of the wizarding world in here. It might pop out somewhere down the road, might make an arc or two about it but will not be the main focus of this fanfiction. Just a heads up guys~

Warning (s): Alternate Universe! Mainly MCU
Child!FEM!Harry
Child Abuse and Neglect

"You know what? Just tell them that I'm on vacation or something. Wait, or you can just tell them to suck it up!" Anthony 'Tony' Edward Stark glared at the piece of the electronic in his hand. He had half of his mind to tell Pepper to fire those old coots right there right now. But knowing his PA turned CEO, she's just going to shut the notion down. Tony grumbled, how dare they try to tell him what to do. He was Anthony Edward Stark! Billionaire, genius, playboy, philanthropist. He owns Stark Industries and he is the one who signs their paychecks every quarter. He's the boss and bosses can do whatever they want.

Stepping out from his black sedan, Tony took in the bustling city of London. It was hell lot of different than Malibu but there's nothing much changed since he was last here. It's been a while since he was here, yes he travelled a lot but he tended to avoid London all together.

"Yep it's been roughly six years. But who's counting?" Tony mussed, his mind travelling back to the reason why he was there in the first place.

…

It was bright sunny day in Malibu, California but it as always wasted on one Tony Stark who at the moment had barricaded himself inside his R&D lab working on his Iron Man suit. His improved Arc Reactor shone brightly against his grey muscle shirt as the man bustled around his lab tinkering away. He was in the middle of fixing from wiring on his helmet when a mechanical voice with a British accent called his attention.

"Sir. Ms. Potts just arrived. She asked me to go get you." JARVIS, Tony's AI said.

Tony stopped, dropping his tools on his working table before yanking the safety goggles from his eyes.

"Yeah. Be right there. Just give a minute will you J?"

"Of course Sir."

The sight that greeted Tony when he emerged from his Lab got the man thinking. His former PA turned CEO of SI and his current love interest; Virginia 'Pepper' Potts was lounging on his sofa staring at the vase filled with Lilies on the coffee table. Tony reminded himself to ask where the flowers came from.

"Hey there Pep!" Pepper titled her head sideways and smiled at Tony, waving him over.

"Hey Tony." She sat up. "Listen, I wanted to talk to you about something."

Tony blinked before shrugging a smirk appearing on his face. "Oh? You're finally admitting about your undying love for me?" He joked.

Pepper looked at Tony. "Really Tony?" She shook her head good naturedly before pulling a folder from her purse and placing it on the coffee table. "Kidding aside Tony, I want you to look over this."

Tony eyed the folder warily before looking right back at Pepper. "Huh…"he reached for the folder and started to scan through it.

"I found this while I was cleaning up some of your files in your office. I figured I'd asked JARVIS about this but decided to just ask you directly." Pepper said, but Tony hardly heard her. His grey eyes were glued on the folder, or rather on the photo that was inside the folder.

It was a polaroid photo of him together with a woman. Both had ice cream cones in their hands as they smiled at the camera. The photo was a little bit faded but Tony could clearly see himself and the woman.

Tony felt a pang on his chest at he stared at the photo. He could recognize those bright green eyes anywhere. There was no one he knew that had that hue of green for eyes.

'Only hers…'

"Lily." He breathe, he ran a finger over Lily's photo.

"So you know this woman? Who was she?" Pepper asked, she was genuinely interested in knowing who this Lily was. She knew that that Tony had many affairs with different women, but what she was curious what caused Tony to react like this.

Tony let out a long breathy sigh before hanging his head. "She was my girlfriend. Met her in London back in 1999."

Pepper blinked. "So she's a girlfriend girlfriend? Not the type of fling you used to have?"

Tony nodded. "Yeah. She was a Med Intern at the local hospital there. We met at some bar and just got along pretty well and a year later we were in a serious relationship." Tony trailed off, his eyes gaining a faraway look.

Pepper was surprised. She never expected Tony to have a serious relationship since well… Since it was Tony Stark. "So where is she now?"

"Dead." Tony mumbled darkly. "She's been dead for 6 years if you want to know how long."

"Tony I…"

"It's okay Pep. She's gone." Tony stood up and sauntered to his wet bar. He needed a drink, a strong one.

"Tony…"

"Pepper stop. Why are you suddenly so interested about this? She was my ex-girlfriend who is dead. It's all in the past." Tony snapped, before downing his drink.

Pepper approached Tony and slide next to him; she didn't look at him but was eyeing the bottle of scotch in front of them. "Because Tony. If what you told me about Lily Evans is true then what I am going to tell you just became more important."

Tony frowned. Confused at what Pepper is talking about. What's so important that she have to bring this all back?

Pepper sighed. "Tony. I don't know if you knew about this. Lily Evans was pregnant when she died in the car accident. Lily died but her baby." Pepper paused. "Her baby survived Tony. And judging by your reaction about her, I am guessing that that baby is yours as well."

Tony froze. "What?"

"Tony. You have a child out there. Yours and Lily."

…

Tony let out a long sigh as he reclined back on his car. His mind was having a hard time processing everything that happened to him in the last 24 hours. He rubbed his forehead with his hand and let out a groan. How come he never knew about Lily being pregnant? Sure they broke it off when he told Lily that he had to return to the US and run his family business. They broke up as friends. But Tony really did loved Lily. Then he found out that she died a year later. Why didn't she tell him?

"Do you know what-?"

"A daughter Tony, you have a little girl out there."

And now here he is back in London, with a single task in mind.

He's going to find his and Lily's daughter, and he's not going to return to California until he finds her.

"Sir?"

"Yeah Hap?" Tony looked at Happy Hogan; his bodyguard slash driver through the rear view mirror. He could clearly see that man was worried about him. Well he was worried about himself as well. He had no idea what he needs to do.

"Do you want to go to the hotel now or you want to go somewhere else first?"

Tony thought for a second before looking back at Happy. They were driving out of London and is approaching Surrey where Pepper had booked him a hotel to stay in. "Just drop me to the nearest park would you buddy?" He needed to think.

"Of course sir."

And done. Yeh this is a trial chapter. (And not to mention short OTL) I want to see how you guys will respond to this. I already have the next chapter thought out. But I'll post it if I get a review or two, so yeah gimme those reviews. (It's christmas!)

The plot is still a bit fuzzy but I promise that everything will clear out as the story progress, granted that you guys want to continue reading. But I might just continue posting or something... The muse is very VERY strong.

Tell me what you think okay? Yes? Good! Thank you!

Until next chapter!
