The story could develop in a very different way. Harry might continue to live a normal Muggle life, completely unaware of his magical abilities. He would probably grow up thinking he was just an ordinary boy, going to a normal school and having normal friends.
In the fanfiction, it could be that Harry's aunt and uncle managed to intercept the letter before it got to Harry. They were so determined to keep Harry away from the wizarding world that they might have found a way to stop the owl or trick the postal system. They could have used some kind of Muggle - magic repelling charm they got hold of somehow. This would be a very interesting twist in the story as it shows how far they would go to keep Harry ordinary.
The story could develop with Harry trying to find a way to get his magic back. He might go on a quest, searching for ancient spells or magical creatures that could help him. For instance, he could seek out the Phoenix, known for its magical healing abilities.
The story could develop with Harry being shunned by some in the wizarding community. They might see him as a has - been or a disappointment. But he might also find a small group of allies who believe in him regardless of his lack of magic. They could help him find new ways to contribute to the fight against evil, like using his knowledge of magic to outwit dark wizards even without being able to perform spells.
The story might progress with Harry becoming bitter about never getting the letter. He could start to resent the wizarding world. However, as he grows older, he might start to notice strange things happening around him that he can't explain. Eventually, he could start to investigate on his own and find out about Hogwarts and the wizarding world in a more roundabout way. This could lead to him having a more complex relationship with the magical community compared to the original story.
The development could also involve a journey for Harry to understand and control these new Deadshot - like aspects. He might struggle with the more violent nature of Deadshot's skills compared to the wizarding code of ethics. Meanwhile, the wizarding world would be in an uproar as they try to figure out what's happening to Harry. There could be a sub - plot where the Ministry of Magic tries to control or stop Harry from using these un - wizard - like abilities, while Harry has to decide whether to embrace them fully to defeat Voldemort once and for all.
Well, if Harry Potter was raised by Orochimaru, his magic might develop in a rather different way. Orochimaru is all about experimentation and pushing limits. He might encourage Harry to explore the darker aspects of magic earlier. Harry could end up with a more unorthodox style of spell - casting, perhaps mixing some of the dark arts with traditional wizardry. But he would also have to fight against Orochimaru's more immoral teachings to stay true to his own values.
His character would likely be more confident. Growing up with a loving mother like Lily, he wouldn't have the insecurities that came from the Dursleys' treatment.
He might become more isolated. As his friends might not fully understand what he's going through with these new memories, Harry could start to pull away from them. This would force him to become more self - reliant and introspective. He'd have to dig deep into his own identity to separate himself from Voldemort's influence, which would lead to a more complex and mature Harry.
His character could become more self - reliant. Without his glasses, he has to find new ways to navigate the world, which might make him more independent. He would learn to trust his other senses more.
Since Vegeta has a very different upbringing compared to the Dursleys or the wizarding world in general, Harry's magic would be shaped by Saiyan values. He might be more inclined to use magic in ways that enhance his physical abilities, like using spells to increase his speed or strength during combat. This would make his magic development more about augmenting his body's natural capabilities rather than just learning traditional wizarding spells.
