The 'God King' concept can make Harry more confident. Instead of the sometimes - doubting boy we see in the original series, he becomes self - assured in his abilities and decisions. For example, he won't hesitate to take on powerful enemies.
It changes his relationships too. His friends might view him with a mix of awe and a bit of distance at first. Hermione might be both proud and a bit worried about how his new power will affect him. Ron could be a bit jealous but also proud to be his friend. And with his enemies, like the Death Eaters, they become even more afraid of him, which changes the power dynamic completely.
The concept of 'god' can completely transform the story. It can introduce new powers and abilities. For example, if a god gives Harry the power of instant healing, it changes the way battles and injuries are dealt with. Also, the moral and ethical framework can be altered. If there's a god - figure dictating what's right and wrong, characters might have to follow a different set of rules than the ones set by the wizarding society.
Immortality can turn Harry into a wiser character. He has the chance to study magic for centuries, and this makes him a master of many different forms of magic. His view of good and evil also changes as he realizes that things are not always as black and white as they seemed when he was young. He becomes more of a diplomat in the wizarding world, using his long - earned knowledge to prevent conflicts.
It changes it a great deal. In the original, Harry was a hero, but still a mortal with limitations. In 'Harry is God' fanfiction, he has unlimited power. For example, he can instantly defeat Voldemort without a big battle. He can also change the very fabric of the wizarding world, like creating new spells or magical creatures.
Well, it can make him more complex. He may have an inner conflict between his good - natured self and the new, darker side that comes with being a fallen angel. This could lead to him being more withdrawn or moody at times.
His character becomes more confident. Since he was raised by a god, he has a certain level of self - assurance that normal Harry might not have. He may not be as easily intimidated by Voldemort or other threats.
In fanfiction, when Harry is a 'feral child', it often makes him more independent. He doesn't rely on the normal support systems like other Hogwarts students. For example, he might not trust adults easily as he's had to fend for himself. This makes his relationships more complex, especially with Dumbledore who he may see as just another authority figure at first.
His view of magic would be different. Instead of just seeing magic as something to be learned from books or teachers, he would see it as a part of nature. So, he might be more creative in his spell - casting, using natural elements in ways that others in the wizarding world haven't thought of. He could be more attuned to the cycles of life and death, and this could make him less afraid of dark magic in a sense, because he understands it as a natural part of the magical world. For instance, he might see the use of certain dark spells as a way to control overgrowth or decay in nature, but of course, he would still have a moral compass about when it's right or wrong to use such magic.
The reincarnation can completely change the relationships. For example, if Harry is reincarnated, he might not have the same bond with Ron and Hermione. He could form new friendships that were not possible in the original story.
The Sentinel concept changes the Harry Potter universe in fanfiction by adding a new type of power dynamic. In the original series, magic is the main power source. But with Sentinel abilities, it's a more instinct - based power. So, it can change how characters interact with threats. For example, a Sentinel Harry would not just rely on spells to fight dark wizards but also on his heightened senses.
It often weakens his relationships with Ron and Hermione. Instead of relying on them, he may distance himself. For example, he might not share his problems with them as he used to.
