His friends might be initially shocked but then find it hilarious. Ron would probably tease him good - naturedly. Hermione, on the other hand, would be more concerned about how to reverse it at first but then accept it as part of Harry's new look. Some of his Slytherin rivals might use it as an excuse to taunt him more, thinking he looks ridiculous.
Well, his relationship with Ginny could be interesting. Ginny might think he looks cute with green hair and it could be a new inside joke between them. His teachers would also react differently. Professor McGonagall might be a bit stern about it, asking him how it happened and if it will interfere with his studies. Professor Snape, of course, would likely make some snide remarks. But overall, Harry's true friends would stand by him no matter his hair color.
His presence could make Harry more protective. Harry might be more cautious in his adventures, not wanting to put his little brother in danger. For example, when dealing with the Marauder's Map, he might be more hesitant to use it if he thinks it could expose his brother to trouble. Also, his friends like Ron and Hermione would have to adjust to having a younger, perhaps more inexperienced, person around. They might feel responsible for him as well.
Some might find it charming. For example, his friends like Ron and Hermione might see it as just another part of Harry's unique personality. It could make him seem more approachable to those who are drawn to his non - conformist ways.
Well, it would probably strengthen his relationship with his friends. His friends would be happy for him to have his parents back, and it could lead to more group activities like family - style outings. For instance, they might all go on picnics together with Harry's parents.
If he transfers, his relationships with his Hogwarts friends would be greatly affected. Hermione and Ron might feel betrayed or worried about him. They might try to convince him to come back. His relationships with his teachers would also change. Some teachers might be sad to see him go, while others might think it's for the best.
Long - term, if his rebellion is for a just cause, some friends might come to understand and support him fully. However, in the beginning, it would likely be a rocky road. His relationships would be tested as he challenges the very institution that has been a big part of their lives. There could be a lot of arguments and debates among them, with emotions running high as they all try to figure out where they stand in relation to Harry's rebellion.
Her powers would likely cause some students to be afraid of her. Those who don't understand the underworld powers might keep their distance. But some adventurous students might be intrigued and want to be her friend just because she's so different.
His friends might be a bit worried at first. Hermione, for sure, would be concerned about the potential danger of having a snake around. Ron might be a bit scared too, considering his fear of spiders and general uneasiness around things that seem a bit dark. But if the snake turns out to be helpful, they might come around.
His relationship with Ginny might be affected. Ginny could be very protective of him and worry a great deal. This could lead to some sweet, tender moments between them as she takes care of him during his seizures.
His relationships would be significantly different. With Ron and Hermione, he might not form the same close bond as in the original story. Since Dumbledore is more of an authority figure, Harry might be more aloof from his peers at first. But he could also attract different friends who are interested in Dumbledore's teachings.
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.
