This story does not have a beta!

A/N: Techno-path, All-speak Tony, seer Tony, All-speak Harry, Draconian-Bruce, All-speak Bruce, All-speak Stephen. Neglectful Albus Dumbledore! Evil Albus? Not Evil Voldemort? Additional notes at the end.

Parings: Remus x Harriet(FemHarry), Regulus(Bruce Banner) x CharlieW

After several outlines and brainstorming I came to realize that two pairings don't work out the way I had hoped for so I am changing them to fit more accurately with what I have in mind and that is Severus Snape x Antonia(FemTony) and Stephen(Stephen Strange) x Barty Crouch Jr. I am changing them for StephenxToni and BartyxSeverus. The reasons why: Barty came to see Stephen like a younger brother and cannot follow through the marriage, and Severus cannot go through as well, if it was Hari than maybe but not for Toni. By the time both Barty and Severus realize that they cannot do it, they had stablish a friendship with each other.

Also I have decided to put them in different houses, even if it would be easier to write them in one house, but they came to the realization that they need to be separate if they don't want to attract unwanted attention. I am still a little undecided on what to do with Voldemort but it will most likely end up with him dead. If you have suggestions for wands they are welcome, regular or custom made.

Summary: After Tony Stark, Bruce Banner and Stephen Strange died, Lady Death ask for a favor, considering the details that she gave them, they accepted. They were reborn in a new universe, different from their own, they wonder if their choice was the right one, the only thing that Tony could think was, damn his conscious and his desire for accountability.

I am not sure is Dorea is James mother, aunt or grandmother, so I set her as James's grandmother.

Chapter 3: Childhood part II

It was after they had turned five that Steph had said that he and Regulus got in contact. It was because of the death of Walburga, Regulus's grandmother, and that he literally had the house all by himself and Kreacher, his elf caretaker, all because of the Fidelius Charm. His great-grandfather Arcturus had confirm Walburga's claim in allowing Regulus to become the official Black Heir, that is because of Regulus Sr. death and Sirius imprisonment in Azkaban.

Stephen could move in after the funeral, they could also try to move Barty, after all they were going to need an adult to help them in the practical aspects of magic and potion making. Barty could also explain to them how the Wizarding World and Hogwarts function and what to expect from the Ministry of Magic and any other thing that they might need or find useful, considering that Barty Sr. works in the Ministry. Hopefully Barty Jr. would teach them about the old-ways that pure-bloods value in order to fit in along with the Black elder who decided to help.

Politics were a battle that one needed to be fully prepare if one wanted to have a fighting chance. Or at least that is what Toni claim. Considering who Toni was in her previous life, her worlds were taken seriously by Stephen and Regulus. Arcturus has taken the duty of doing what was necessary to get the Lestrange heir out of the orphanage, and helped them in their political education.

The Black adult had agreed to help them, and keep quiet about Barty Jr. He was offended by the treatment that Hari and Toni were subjected by that "Light" side and by their Muggle relatives, they might have been born Potter but they still had Black blood. They were especially angry at Stephen's treatment by Dumbledore as he is Lestrange-Black, and should had never being put in an orphanage considering that he had two living aunts that could had taken him in.

Toni and Hari were still require to go back to the Dursley but Toni had some manage to convince Petunia to leave them at the library for most of the day instead, that way they were out of her hair and Toni could get some schooling done, they would only be at Privet Drive for the nights. However they did not spend all of their time in the library, Regulus had included them as well as Arcturus in the secret of the Fidelius, so that could go and learn about magic (mainly theory) and all the customs of Purebloods that they needed to know being member of the House of Potter.

With Arcturus's help their magical schooling was progressing faster than what they had expected. And Toni had won a bet with the muggle librarian, so she was to help them get their muggle education. Considering that they were geniuses in their previous lives, the regular schooling was going to be a piece of cake, she only had to help Hari with her education. Both Regulus and Stephen took advantage of that bet as well, if they could advance their muggle education the better. Considering that they had their knowledge of their past life they were going to take advantage of it.

Toni decided to reestablish Stark industries in both worlds, in the muggle world it would be a technological based industries along with medical research and development, while in the magical world it would be for potions development, charms, magical objects, and other things. One thing that did not change in Toni was her knowledge of business and how to handle them. She decided to wait a little so she could make business plans as well as manage what their parents left them, she was planning on letting Hari have the inheritance as Hari was the first born so it belong to her, but that didn't meant that she would not try to expand the money.

She wanted to make sure Hari had a life were she didn't have to worry about things that they do now, the lack of room and the lack of food mainly, Toni didn't care much, she was used to the lack of food and sleep from her previous life, but that didn't meant that she was unaware of its toll. Undernourishment was a real pain in the ass, he was short as Tony and now it seems that both she and Hari were going to be short as well. She had to make sure that her sister has a happy life, to not let her be used or manipulated, she was good at that, there was a reason why she was called The Merchant of Death while she was Anthony Stark.

As The Merchant of Death Toni knew the game of manipulation and politics, and she would make sure to use everything in her disposal to help Hari, Stephen and Regulus not only survive but to succeed as well. There were a lot of things that she did not like and others that seem suspicious. She was going to make sure that they get alive of whatever that was happening or was going to happen, another thing that Toni found out was that her being a futuristic made her be a low-medium level seer, so she had some glimpses of the future and plan accordingly, and Stephen's history with the time stone had him in a similar position, so both of them made plans and Regulus would go over them to see if they need to be modify.

Getting Barty was not as difficult as they had expected, they had manage to convince Winky the house-elf to help them because they only wanted to help her young master. Hopefully the elf would not tell Crouch Sr. about Kreacher, Arcturus and Regulus Jr kidnapping his son, while Toni, Hari and Stephen waited for them and plan about his mental health. That was an issue that they still hadn't found an answer to.

The next day after they had taken Barty Jr. they found out that Winky was fire by Crouch Sr. that work well into their plans as they could keep Winky as Barty's main caretaker. They still needed to find a way to help Barty's mental health. Convincing Crouch Jr. to keep low and help them was not so difficult as well, they just had to remind him about Stephen being the Dark Lord's godson to keep him in line and help with their plans. The good thing was that they manage all of that in one year. They were six and had many plans for the future, Lady Death was happy to see young Hari was not alone and that her chosen guides were doing well with the limited resources and information they had, so far she was happy.
