Notes

This is cross-posted on AO3

None of the characters from the Marvel world or the Harry Potter world belongs to me, I may use creators license in the book, and some ideas may be mine, but none of the characters or known facts about them belongs to me. Also, I've had to mess around with the timeline a bit so everything would fit together, Harry is born in 2000, but the first Avengers movie still takes place in 2012, which would be the year that Harry goes off to his second year at Hogwarts, so the story will take place in 2013 and beyond, however, the prologue takes place in 1999, and Lilly and James die in 2001.

This book was inspired by a book I read called "Man of Iron, Child of Magic," while the idea of how Tony is Harry's father, and that Steve goes with Tony to fetch Harry, and few other things here and there, a lot passed that is from my own ideas, and if you recognise anything from anywhere else, I either had no knowledge of it, or it's also a favourite prompt of mine.

This is the first time I am writing a book, and while I am Proofreader, for a translating team, and have edited my school's newspaper, when I was still in high school, I might still make a few mistakes, as reading over your own work is different from reading over other's. So please let me know if I make any mistakes.

Prologue

It was September time in London and Tony felt the chill through his suit he was wearing as he exited the vehicle to some other event he was supposed to attend, as he was the son of Howard Stark and had a legacy to continue, that didn't involve heavy amounts of alcohol and some one-night stand never to be seen again.

Tony was not looking forward to a night spent around snotty people who believed themselves above the rest. He was especially not looking forward to being around the people who thought he should be more like his father or the people who thought he should find a good woman and settle down and start a family, just so he could be a screw-up of a father like his father was.

After entering the building, Tony shrugged off his outer coat to be left standing in a three-piece black suit, with a red handkerchief in his breast pocket sticking out. Tony had already spotted the younger females looking at him with lust, even a few of the older married ones, but he wanted nothing to do with them. He was there to make a few large donations to a couple of different charities and then he had planned on getting drunk afterwards before his return flight home.

Later in that evening saw Tony approaching the bar after signing off a few checks and doing the bare minimum of socializing required at these types of events. Tony saw a pretty red-headed lady sitting at the bar, who seemed to be enjoying the event as much as he was. Deciding he may as well have some fun, he takes the open seat next to her and orders a drink, before turning to her to start up a conversation.

After spending the remainder of the night talking to the beautiful red-head lady, Lilly, Tony wants to invite her over. Their conversation had been pleasant, and Tony thought they had hit it off really well. Lilly had turned around and motioned at a guy to come over, Tony was curious as to why, Lilly turned back around and looked him over again, before smiling.

The man walked up behind Lilly and placed his hand on her shoulder holding eyes full of promise. Lily had then proceeded to introduce the man, James, as her husband. Tony's heart was sinking at the thought of this beautiful lady already being taken, and that this couple wanted something he wasn't into. Not that he didn't go both ways, just not at the same time. Tony would wait and see if that's what they really wanted; it wouldn't be the first time someone asked for something absurd of him.

Lilly had looked almost hesitant to speak again to Tony before she got right on it and had profoundly told Tony about how she and James had been married for the last year and a half, but they were unable to have any children due to an accident James had had in his last years of high school. She had then gone on about how James was from old family blood and if they had a child that didn't resemble him, their child would not have an easy life. Lilly had stopped at this point and had figured out what she basically telling him because James had remained silent besides for any gestures of agreeance. Lilly had looked over at James and it was obvious these two had shared a moment and that they were desperate at this point. James had got the confidence to finally ask Tony what they had wanted to since Lilly had called him over, and that was if he would be willing to donate his genetic material to them because Tony had similar features to him.

Tony was going to deny them of this offer, as he didn't a child of his own running around, but after he had looked into both their eyes and could see the amount of pleading in them, as well as hope, he couldn't refuse them. Tony agreed to donate his sperm to them, and it would all be done scientifically and that there would be no physical conception of the child. He also got them to agree to send him a photo of the child when it was along with the child's name. Also, with the option that when the child turns twenty-one, and if Tony had no children of his own, he would be allowed to see his off-spring and give him the option of taking over his company, if he didn't have someone he could trust. Tony asked to see the kid on his twenty-first even if he did have his own children, not that he thought he would, just to see him, and only be known as an old friend of theirs. James and Lilly agreed with this all, although that had seemed reluctant on the part of their child possibly taking over Tony's company, but Tony had reassured them, that it wouldn't be forced on the child, and he would probably have someone to take over anyways.

After that evening Tony and the Potters, as Tony had learnt later on, only met up one other time, and that was when Tony came to hand over the infamous cup to them, as wish them well and the best of luck with the pregnancy and their futures. Unknowingly to him that Potters will have written in their wills, once their ball of sunshine Harry James Anthony Potter, that should anything happen to them, that Tony was to be contacted and Harry to be put into his care. A week after Harry's birth, Tony received an image of Lilly and James holding a tiny baby in their arms, on the back read Harry's name and his date of birth, thirty-first July 2000.

Sadly, after the tragic night of Halloween in 2001, their wills were never opened and Harry was sent to live with Lilly's remaining family. A household where Harry grew up unwelcome and unloved. Harry was verbally, mentally, and emotionally abused in his childhood with the Dursleys, even physically abused at times, however rarely, he still was. He grew up bullied by his own cousins and under the staircase of house number 4 Privet. At age 11, Harry learnt he was a wizard and was to go to Hogwarts school of witchcraft and wizardry, where he was sorted into Gryffindor. Harry spent his first year at school battling trolls and possessed teachers, hiding dragons, creating friends with Ron and Hermione, and creating a rival with Draco Malfoy.

Tony had also spent the last eleven years wasting away in alcohol and sex when he wasn't stuck in his workshop inventing new weapons or other things, but that was all before he was kidnapped and forced to create a weapon for terrorists, all the while shrapnel was heading towards his heart, only being slowed done by a car battery. After Tony freed himself, his company stopped making weapons altogether and Tony became Iron Man.

The year Harry went into his second year of schooling at Hogwarts, was a big year for both Harry and Tony. Across the pond in America, Tony, along with the Avengers dealt Loki's and the Chitauri's invasion in New York. After the attack Tony realised that he needed to get his priorities right, so he asked JARVIS to keep a lookout for the names Lilly Potter, James Potter, Harry Potter, or any other people that might be related to them. Meanwhile, Harry had set off for his second year, where he battled with a basilisk and saved Ron's little sister Ginny from dying at the hands of diary Tom Riddle, or otherwise known as Voldemort.

On Harry's return to King's Cross station from Hogwarts, Harry had felt sick the whole train ride back, he was not looking forward to spending the summer with the Dursleys, but it was for the greater good, as he had once heard Dumbledore say to McGonagall one day in passing. After being fetched by his so-called family, surprised to see them all in the car, but after seeing all the shopping bags loaded in the backseats next to Dudley, Harry lost his shock as he made to sit in the trunk with large school trunk. It was on this trip home that they were t-boned by a drunk driver and rushed to the hospital. Vernon had died on impact, and Petunia was rushed into operation, to be eventually put into the ICU ward, Dudley had been left with a broken arm and leg, with a few fractured ribs, him being saved from a worse fate due to Harry's magic. Harry himself was covered in bruises and had cracked a good rib or two due to hitting his school truck on the impact, his left arm was also broken from being pushed up against the trunk. Both Harry and Dudley had been in a general hospital room, but Dudley's Aunt Marge had been quick to leave with him and not Harry, not speaking to him unless it was to blame him or to tell him he deserved ever injury he had. It was not one day later that JARVIS notified Tony that a hit had come up on Harry.
