Physically, he might become more rugged and less concerned with his appearance. Without the trappings of wizarding society, he may grow a beard or let his hair get long and unkempt. Mentally, he could become more introspective. He has time to think about all that has happened in his life, and this could lead to a deeper understanding of himself and the events that shaped him.
One possible reason could be to escape the fame and the constant scrutiny that comes with being 'The Boy Who Lived'. After all the battles and chaos, he might just want some peace and quiet to heal his mental and emotional wounds.
It makes him seem more self - centered at first glance. Traditionally, Harry was seen as the savior of Britain, so leaving it to its fate goes against that heroic image. But on a deeper level, it could also show his growth into a more complex character who has his own needs and boundaries.
It could change his life by giving him a new form of magic. For example, he might be able to combine the power of the stand with his existing magic, making his spells more powerful.
He could meet new witches and wizards from different cultures. For example, he might run into a powerful African wizard who has unique magical abilities related to nature magic. Or he could meet a Japanese witch who specializes in charm - making that is based on ancient Shinto beliefs.
The dynamics within Gryffindor would be greatly affected. His friends like Ron and Hermione would be confused and sad. The Gryffindor house would lose one of its most iconic members, and there might be a power shift within the house. Other Gryffindors might feel less confident without Harry around.
If the device in the fanfiction is a time - traveling gadget, it could completely transform Harry's life. He could go back in time to learn from the founders of Hogwarts, understand the origin of certain dark magic, and use this knowledge to prevent future disasters in his own time. It would also give him a chance to meet his parents and gain a deeper understanding of his own heritage.
His living conditions would change drastically. Instead of living in the wizarding world, he'd be in palaces. He'd have servants and all the luxuries that come with royalty. His friends at Hogwarts would be replaced by new acquaintances in the royal circle. He'd have to adapt to a very different set of rules and expectations.
A consequence could be that Harry starts to feel a sense of alienation from the wizarding community. Since he is isolated by the Order, he might not be as in - touch with what's going on outside his isolation. This could lead to him making decisions based on incomplete information when he finally gets involved again. Also, his mental health might suffer as isolation can be very tough on a person's psyche, and he could become depressed or overly anxious.
Another change in perception in Harry Potter fanfiction is regarding the relationships. Take the relationship between Harry and Snape. In the official books, their relationship is mostly antagonistic. However, in fanfiction, authors may re - imagine their relationship as a more mentorship - like bond. This could be due to exploring Snape's true motives earlier in the story or by changing certain events that happened between them. It gives a fresh perspective on the characters and their possible interactions.
He might become more in tune with nature. Since the Phoenix is a symbol of rebirth and nature in the wizarding world, Harry could develop a stronger sense of environmental magic. For example, he could be able to communicate with other magical creatures more easily, not just the Phoenix.
