Eragon would probably have a different view on power. Since he was raised by dragons, he would see power as something to be respected and used sparingly, as dragons do. He may also be more fearless, as dragons are often seen as powerful and fear - inspiring creatures. His communication skills with dragons would be far superior, and he might struggle to communicate as effectively with humans.
One idea could be that Eragon discovers unique dragon magic only accessible to those raised by dragons. For example, he might be able to communicate with all dragons on a deeper level, not just his own. Another plot could involve him facing challenges from dragon - haters who fear his special bond with the dragons. They might try to break the bond or harm him.
His character would likely be more wild and free - spirited. Dragons are not bound by human rules, so Naruto might be less inclined to follow traditional ninja etiquette.
He'd likely be more fearless. Dragons are fear - inspiring creatures, and growing up with them would make Harry less intimidated by threats. He might be more direct in his actions and less likely to second - guess himself.
Harry would likely be more wild in a sense. Dragons live by their instincts, and he'd pick up on that. His magical abilities could be more primal. Instead of relying on the spells taught in Hogwarts, he might use magic in a more raw and unrefined way. Also, his sense of loyalty might be more towards the dragons rather than the wizarding community initially.
Harry would probably be more wild and less bound by wizarding society's norms. Dragons don't follow human rules, and being raised by them would make Harry question and break free from some of the traditional wizarding ways. He might be more instinctive in his actions and decisions, just like how dragons act on their instincts.
His relationships would be very different. He might find it hard to relate to other wizards at first. He'd be more used to the company of dragons, so he might seem a bit aloof to humans. But he could also form very deep and loyal friendships because of his dragon - influenced sense of loyalty.
Well, one possibility is that Naruto would grow up with dragon - like powers. He might be able to breathe fire or have super strength. And his view of the ninja world would be very different, as he was raised in a dragon's lair rather than the Hidden Leaf Village.
Her character development would likely be different because of her gender. She might face more discrimination from the Viking community at first. However, her time with the dragons could make her more resilient and determined to prove herself. For example, she may be more cautious in some ways as females in Viking society were often expected to be, but her dragon - raised side could make her bold when it matters.
Well, in many fanfictions, it could be Igneel and another dragon like Metalicana. Igneel is Natsu's adoptive father in the original series, and Metalicana is Gajeel's dragon. Combining them in a fanfiction as Natsu's caretakers could lead to some really interesting character dynamics.
Another theme is identity. The dragon blood makes Eragon different from others. Fanfictions may focus on how he struggles to come to terms with this unique part of himself, like in stories where he tries to hide his dragon - blood - related traits in a normal human society within Alagaësia.
