In the original Harry Potter series, Harry is a part of the British wizarding community, with its own set of rules, traditions, and power structures. However, in the 'Harry Potter raised by Zeus' fanfiction, he would be part of the Greek mythological cosmos. His upbringing under Zeus would mean that his values, his understanding of power, and his relationships would all be different. For example, in the original series, friendship at Hogwarts was important, but in this fanfiction, he might have a different set of relationships with demigods and other creatures from Greek mythology. His concept of heroism would also be influenced by Greek ideals rather than the more modern - day heroism presented in the original Harry Potter books. Moreover, the way magic is perceived and used would be distinct, as Greek magic has its own unique characteristics compared to the magic in the wizarding world.
The plot would likely be very different. In the original, Harry was raised by the Dursleys, which led to a lot of his character development. In fanfiction - raised Harry, he could be raised by wizards who teach him magic from a young age, so he'd be more advanced when he gets to Hogwarts. His understanding of the wizarding world would be different too.
The biggest deviation would be in Harry's character. In the original, he is kind - hearted and values friendship and justice. Raised by Sephiroth, he could be more cold - hearted. Also, the power dynamics would change. Harry might not rely on the same magic sources as in the original but instead on Sephiroth - inspired powers.
The magic system would be different. In the original Harry Potter, magic is mainly about spells and potions. But with Link as a mentor, Harry might use magic in a more physical and instinctive way. For example, he could combine magic with sword - fighting skills. Also, his social skills would be affected. Link is often a lone wolf, so Harry might be less sociable and more independent compared to the original Harry.
The most obvious deviation would be his upbringing. Instead of being bullied and neglected by the Dursleys, he'd be in a nurturing environment. This would likely make him less timid and more self - confident. Also, his knowledge of the wizarding world before Hogwarts would be far greater.
The biggest deviation would be in Harry's upbringing. Instead of growing up with the Dursleys, he's with the Queen. So his values and manners would be very different. He'd be more accustomed to a life of luxury and formality. His attitude towards authority figures in the wizarding world might also be different. He might not be as intimidated by the Ministry of Magic officials as he was in the original story.
In this fanfiction, the way Harry is perceived by others would change a great deal. In the original, Harry was often seen as a hero - in - the - making boy. As a girl, she might be seen as more delicate or have different expectations placed on her. This would impact how she is treated by the Ministry of Magic, other students, and even the magical creatures. Also, her magical abilities might be explored in a different light. Maybe she would be more intuitive in her magic due to her different upbringing as a girl.
The biggest deviation would be in Harry's upbringing. In the original, he was raised by the Dursleys, which was a very different environment compared to a Yakuza - influenced one. His values and skills would be very different. For example, he might not be as meek as he was in the beginning of the original story.
The tone would be a major deviation. Instead of the mix of adventure and coming - of - age in the original, it would be full of dread. Harry's character would be less optimistic.
The biggest deviation would be in Harry's character. In the original, Harry is inherently good - hearted. But with Crowley as his mentor, he might be more morally grey. His decisions would be based more on self - interest rather than the common good.
The biggest deviation would be in Harry's upbringing. Instead of the Dursleys, he has Davy Jones as a mentor. So his moral compass would be different. Also, his magical knowledge would be a blend of wizardry and the strange magic of Davy Jones.
