He would likely be more stealthy. Natasha is known for her ability to move quietly and unnoticed, and Harry could inherit this trait. He might also be more physically fit and have better combat skills than in the original series.
Yes, it is possible. The combination of the magical world of Harry Potter and the spy - like skills and background of Natasha Romanov can create a very interesting and unique plot. For example, Harry could inherit some of Natasha's combat and espionage skills, which would be very useful in his battles against the dark forces in the wizarding world. He could use his stealth and combat abilities to outwit his enemies in a different way compared to the traditional magic - only approach in the original Harry Potter series.
She could be more resilient. Growing up as a black in a predominantly white wizarding world might have toughened her up. She may also be more community - oriented, drawing on the strong sense of community often found in black cultures. And she might be more in touch with her emotions, not suppressing them as much as the original Harry did.
Lemon could be brave like Harry. Since they are twins, she might inherit the same Gryffindor - like courage. She could be the type who doesn't shy away from standing up to bullies at Hogwarts, just like Harry does with Draco Malfoy.
He would probably be highly intelligent. Mycroft is known for his brilliant mind, and Harry would likely inherit that. He'd be able to analyze situations quickly and come up with solutions. Also, he might be more introverted compared to the original Harry. Mycroft is not a very outgoing person, so Harry could be more reserved, spending time thinking and planning rather than being in the spotlight all the time.
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.
A possible plot might be that Harry uses his Superman - like powers to help the wizarding world during times of peace as well. For example, he could use his super strength to rebuild parts of Hogwarts that were damaged in previous battles. Or he could use his flight to quickly transport important magical artifacts from one place to another. Also, there could be a plot where the wizarding community is initially afraid of Harry because of his non - magical powers, but he has to prove that he is still one of them and is there to protect them.
There could be a conflict between Harry and the existing wizarding order. The Ministry of Magic might view Harry as a threat because of his connection to Orochimaru. They would be worried that he might bring dark magic into the wizarding world. Harry would then have to fight against the prejudice and suspicion of the wizarding community, while also trying to figure out his own identity and loyalties.
Well, a plot could revolve around Harry inheriting Natasha's ability to read people. In the wizarding world full of secrets and hidden motives, this would give him an edge. He could sense when someone is lying or hiding something important. Also, there could be a story where the Avengers and the wizarding world have to team up because of a threat that concerns both, and Harry is the bridge between the two groups.
Hermione would definitely be one of his allies. She is smart and would be able to help him research about his new identity and how to control his powers. For example, she could find ancient texts in the Hogwarts library that relate to both the wizarding world and the Greek gods.
His friends from Hogwarts could still be his allies. Hermione would use her intelligence to help him understand his new situation. Ron would be there for moral support. Additionally, any friends or allies that Rias has in her world could also become Harry's allies. They might be magical creatures or other powerful mages.
