The puppy could change Harry's life in terms of relationships. His friends would all be drawn to the cute puppy, and they would spend more time together because of it. Also, it could potentially change how some of the other students and teachers view Harry. Some might see him as more caring because he's taking care of the puppy, while others might think he's being irresponsible for having a pet at school.
The puppy would add a lot of fun. Harry would have a new friend to play with. He could take the puppy for walks around the Hogwarts grounds. It would also give him a sense of responsibility outside of his usual wizarding duties.
If Snape adopted Harry, his life would be a mix of challenges and new opportunities. Harry would have to adapt to Snape's strict rules and high expectations. However, he would also learn things from Snape that Dumbledore might not have been able to teach him. For instance, Snape could give Harry a more in - depth knowledge of the dark arts and how to defend against them. Socially, Harry might face some difficulties as Snape is not a popular figure, but in the long run, he could become more independent and self - reliant under Snape's guidance.
It could make him more confident. With the symbiote's powers, he'd feel more capable in dangerous situations.
His relationship with Hermione and Ron would be strained at first. They would be confused and a bit scared. But as they see Harry resist the dark side, they would become more supportive. With Dumbledore, there might be a new level of secrecy and mistrust at the start, but Dumbledore would likely keep an eye on Harry to see how he develops. As for the other students, many would be afraid and avoid him, but some might be curious and try to befriend him to see what it's like to be around the heir of Voldemort.
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.
Harry Potter reborn as a Jedi would have a different upbringing. Instead of growing up with the Dursleys, he'd be in the Jedi Temple. This would change his perspective. He'd be more focused on the balance of the Force rather than the battle between good wizards and bad wizards. His relationships would be different too. He'd form bonds with other Jedi, and his loyalty would be towards the Jedi Order. His character would be less about the magic of spells and more about the power of the Force, but his core values of bravery and standing up for what's right would remain.
Darth Vader's training would make Harry more self - reliant. In the wizarding world, Harry often has help from his friends. But Vader would force him to rely on his own abilities more. Also, Harry's perception of good and evil might be blurred. Vader's teachings are not as straightforward as the ones in the wizarding world.
Harry might become more confident. Rebbekah is a strong character, and under her influence, Harry could learn to be more assertive. He'd no longer be just the boy who lived, but a part of a different magical family with different values.
He'd probably be more confident. Dante is a very confident character, and if Harry is his son, he might inherit that trait. He'd be less likely to be intimidated by bullies like Draco or even the Death Eaters.
With Hermione and Ron, it would be very different. If Harry is de - aged, they might see him as a younger, more vulnerable friend. Hermione could become even more protective, like an older sister. Ron might be a bit confused at first but would probably still be his loyal friend. Their dynamic would shift from equals to something more like Harry being the 'little one' they need to look after.
In this fanfiction, Harry's life at Hogwarts would be full of new discoveries. He could find secret passages that are overgrown with plants but are only visible to him because of his connection to Demeter. His friends might be a bit in awe of his new powers. He'd also have to deal with some jealousy from other students who don't have such unique abilities. And when it comes to Quidditch, he could use his nature powers to his advantage, like creating a gentle breeze to help him fly faster or making the grass on the pitch grow in a way that confounds his opponents.
