Peter might be more confident. With his parents alive, he has a support system. They could guide him, which might make him less impulsive. He may not have to figure out everything on his own like in the original story where he's on his own. So his decisions could be more thought - out.
His character could become more closed - off. Losing Peter, who was such an important part of his life, might make Yondu build higher walls around himself to avoid getting hurt again.
The embarrassment can also help Peter grow in his relationships. He may learn to laugh at himself more, which can endear him to the other Avengers. And he might become more open with them about his insecurities. This new - found openness can lead to stronger bonds within the team as they understand him better. In the long run, it shapes Peter into a more well - rounded and relatable character in the fanfic.
Naruto would likely be more confident earlier. With his mother around, he'd have someone who unconditionally loves and supports him from the start. He wouldn't have to seek as much approval from others. His growth might also be more focused on learning Uzumaki techniques rather than just trying to prove himself. He could be more stable emotionally as Kushina could help him deal with his inner turmoil, like the Nine - Tails situation.
Neville would become more confident. Knowing that his parents are healed, he no longer has that underlying pain and worry. He would be more assertive in his actions and decisions, and might even take on more leadership roles at Hogwarts or in the wizarding world in general. For example, he could be more outspoken in the DA meetings.
In the fanfiction, Peter's character development is quite remarkable. Initially, he's a bit naive and inexperienced in the world of the Avengers. But as time goes on, he picks up on their combat strategies. He becomes more strategic in battles, not just relying on his spidey - sense. Socially, he grows too. He learns to communicate better with the other Avengers, understanding their different backgrounds. He also starts to mentor new, younger heroes, showing how far he's come from being the new kid on the block.
There could be. Fanfiction is a vast world full of various creative ideas. Writers might be attracted to the idea of Tony and Pepper being Peter's parents as it can bring new storylines, such as how they would raise Peter in the Stark household, with all the technology and wealth at their disposal. It could also explore how Peter's powers would be incorporated into their family dynamic.
She becomes more nurturing. In most of these fanfictions, Natasha, who is usually seen as a tough spy and fighter, softens up. For example, she starts to cook for Peter, something she might not have done before.
He becomes more confident in some ways. With wealth, he has more resources at his disposal, so he can approach problems more boldly. For example, he might not hesitate to take on bigger threats because he can afford the necessary equipment and backup.
Peter often develops a stronger sense of family. Before, he might have felt alone, but with Natasha as his adoptive mother, he starts to feel more secure. He becomes more confident in himself too. For instance, he might be more willing to stand up to bullies at school.
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.
