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.
Well, if his parents are alive, they can offer him emotional support. For example, they can be there for him during tough times at school or when he's bullied. They might also help him with his scientific interests, which could lead to different developments in his superhero journey.
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.
His communication skills could be affected. Instead of his usual witty banter, he might be more growls and short, sharp commands. This is because his feral side has taken over some of his human communication tendencies. Also, his relationships with others would shift. His friends might be a bit scared of this new side of him at first, but then try to help him come to terms with it.
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.
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.
Well, it could make Hermione a lot more conflicted. Growing up with Death Eater parents, she might constantly struggle between the values she's exposed to at home and the ones she discovers at Hogwarts. For example, she might initially be more hesitant about befriending Harry and Ron due to her family's possible prejudice against 'blood traitors'. This could lead to a more complex and nuanced character arc as she gradually breaks away from her family's ideology.
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.
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.
