His relationship with the Avengers would be different. They might see him as Natasha's legacy. For example, Clint might take on a more protective role towards Peter, seeing him as a part of Natasha that still lives on. And Tony could be more involved in mentoring Peter, not just because of his own interest but also because of his respect for Natasha.
Peter's relationship with his friends at school would also change. He might be more secretive about his home life and his connection to Natasha. But at the same time, he could be more confident in himself, knowing that he has the strength and skills passed down from his mother. He might also use Natasha's wisdom in dealing with bullies or difficult situations at school, like using her tactics of misdirection or using his opponents' strength against them.
Peter's relationship with the Black Widow - related characters would be unique. He could meet characters from Natasha's past in the Red Room. These characters might either try to use him or protect him, depending on their own agendas. Also, his relationship with Yelena could be complex. Yelena might initially be skeptical of Peter but later come to accept him as part of the family.
Peter might be more reserved and calculating like Natasha. Instead of his usual impulsive self as Spider - Man, he would think things through more carefully. His sense of humor might also be a bit darker, influenced by Natasha's past and her own brand of dry humor.
Peter would probably have a closer relationship with the Avengers, especially those who were close to Tony. For example, he might have a special bond with Pepper, who would be like a mother figure to him. And he would be seen as more of an insider from the start compared to his normal origin. He could also get more direct training from the likes of Captain America or Thor.
One possible plot could be that Peter grows up with Natasha's skills and values. He might be trained by her in combat and espionage. For example, he could learn how to use different weapons and how to deceive enemies just like Natasha. Maybe they go on secret missions together, with Peter gradually proving himself as a worthy heir to Natasha's abilities.
At first, it could be strained. Loki might not be the best father figure right away. He may be more focused on his own goals and not fully understand how to be a dad. Peter, on the other hand, would be confused and perhaps a bit resentful.
His sense of loyalty would be strongly influenced by Bucky. Bucky is known for his loyalty to Steve, and Peter would inherit this trait. He would stand by his friends and family no matter what. Also, his combat skills would progress rapidly under Bucky's tutelage. He'd become a formidable fighter at a young age, and this would boost his confidence but also make him a target for villains.
The son might have a very close relationship with his father's friends. For instance, if Edward has a best friend, the son could look up to that person as an uncle - like figure. They could go on adventures together and the friend could teach the son things that Edward might not be able to.
He might be more disciplined. Since Peggy was a very no - nonsense and disciplined person, Tony could inherit those traits. He may be less reckless compared to his original character in the MCU. He would also have a different sense of purpose, perhaps more focused on upholding Peggy's values.
He would likely be more otherworldly. Since Gabriel is often associated with the divine or supernatural, Harry might have an air of mystery about him. His powers could be on a different level compared to the regular Harry Potter character, perhaps more angelic in nature.
He would be more physically capable. Natasha's training would make him better at hand - to - hand combat compared to the original Harry. He might also be more confident in dangerous situations.
Peter's powers would be a blend of his parents' skills. He could have the super - soldier - level strength and stamina from Bucky, which would make his web - slinging and acrobatics even more powerful. From Natasha, he might gain the ability to analyze situations quickly and come up with effective strategies on the fly. His senses could be enhanced in a different way too. Instead of just the typical spider - sense, he could have a more refined sense of danger detection, like Natasha's ability to sense threats in the spy world. Also, his fighting skills would be a unique combination of Bucky's military - style combat and Natasha's fluid and sneaky fighting moves.
