Well, Harry's relationship with the Slytherins could take an interesting turn. Normally, there's a divide between Gryffindors and Slytherins. But if Harry were acting like Riddle, some Slytherins might be intrigued. They might see him as a kindred spirit, especially those who admire Riddle's power and cunning. However, the more noble - minded Slytherins would still be cautious. And his relationship with the teachers other than Dumbledore would also change. They would be on high alert, watching Harry's every move more closely, suspecting that he was headed down a dark path.
His relationship with Ron would likely become strained. Ron, who values loyalty and friendship above all, would be put off by Harry's new - found Riddle - like behavior. Harry might start to see Ron as beneath him or not as useful, similar to how Riddle treated his less - than - worthy followers. With Hermione, she would probably try to reason with Harry at first. But as he continued to act like Riddle, she would become frustrated and might distance herself, as she would see the danger in Harry's new attitude.
Her relationship with Dumbledore would be extremely complex. Dumbledore, knowing her parentage, would be both watchful and perhaps a bit more guarded around her. He would try to guide her away from the dark path but also might not fully trust her at first. With Ron and Hermione, they might initially be shocked and a bit hesitant. However, their loyalty to her as a friend could eventually overcome their doubts, but there would always be a bit of unease, especially when it comes to using dark magic.
His relationship with Ron would be very different. Ron might be initially distrustful or even hostile towards Harry in Slytherin. But as the story progresses, they could come to understand each other better. Harry's relationship with Hermione could also change. She might be more cautious around him at first, but then realize that Harry is still the same person deep down. And his relationship with Draco would be much more complex. They could start as rivals, but then become allies in some situations, as they both have a connection to Slytherin.
The resemblance might also affect Harry's romantic relationships at Hogwarts. For example, if he had a budding romance with Ginny, Ginny might have some mixed feelings. On one hand, she loves Harry for who he is, but on the other hand, the visual reminder of Voldemort in Harry's appearance could cause some unease. Some other students who had crushes on Harry before might lose their interest, while new students who are intrigued by the mystery of his appearance might be attracted to him. Overall, it would create a lot of complex emotions and changes in how people interact with Harry at Hogwarts.
It re - imagines the universe by flipping the dynamic. Harry is usually the hero, but here he's acting like the main villain. This changes the power balance in Hogwarts and among the characters. For instance, instead of being a defender, he could become a threat to his friends.
One possible plotline could be that Harry starts to show an interest in dark magic like Tom Riddle did. Maybe he becomes overly ambitious in his studies, trying to outperform everyone in a way that borders on the obsessive competitiveness that Riddle had. Another could be that Harry begins to isolate himself from his friends, just as Riddle did when he was at Hogwarts, as he delves deeper into the knowledge that Riddle once pursued.
His relationship with Hermione would likely change. Hermione is used to the human Harry, but now she has to deal with a phoenix - form Harry. She would probably be very curious and start researching immediately about any historical cases of humans turning into phoenixes. Ron, on the other hand, might be a bit more hesitant at first. He's used to the regular Harry and this new form might seem a bit strange to him. But overall, his friends would be protective of him. They would want to make sure that he is safe in this new form and not exploited by those who might want to use his phoenix powers for their own gain.
His relationship with Hermione would be very different. Hermione, who is an advocate for house - elf rights, would be in a strange position. She might try to help Harry break the spell, but also be conflicted about treating him like a normal house - elf. With Ron, Ron might not take Harry as seriously at first in his house - elf form, but then realize that it's still Harry and they need to work together. And with Snape, Snape would probably be even more dismissive of Harry as a house - elf, but Harry would still find ways to get under his skin.
With Dumbledore, it would be a complex relationship. Dumbledore would be cautious yet intrigued by Harry. He would want to guide Harry away from the potentially dark path that his Nathrezeim upbringing could lead him to. Harry, on the other hand, might be resentful of Dumbledore's interference at first.
His relationship with his enemies would change significantly. Voldemort or his Death Eaters might not recognize Harry as a rabbit at first, which could give Harry an advantage in some ways. However, if they did find out, they might see it as an opportunity to either capture or harm him more easily. Among his friends in Gryffindor, they would all be very concerned. Neville, for example, might try to use his knowledge of Herbology to find a way to reverse the transformation. And Ginny would be especially protective, seeing Harry in such a vulnerable state as a rabbit.
Some of the more traditional wizarding families, like the Malfoys, would likely oppose Harry's actions. They have always held a certain view of the goblins as being inferior. This would further widen the gap between Harry and those who uphold such old - fashioned and discriminatory views. However, among the younger generation of wizards who are more open - minded, Harry's actions could inspire them to re - evaluate their own views on the goblins, and he could gain new friends and supporters from this group.
