Definitely Hermione. She's so smart and resourceful that she can be a great asset to Harry in any alternate universe situation. Luna Lovegood could be another common character. Her unique perspective on the wizarding world can be really interesting in a different universe setting. And Snape, his complex personality and his connection to Harry's past can make for some really engaging storylines in these fanfictions.
Hermione Granger often appears. Since she is Harry's best friend in the original series, she can play an important role in helping Harry understand the new alternate universe. Ron Weasley is also common. His loyalty and humor can add interesting elements to the story. Dumbledore might also show up. His wisdom can be crucial in guiding Harry in the strange new world.
In some fanfictions, there could be a magical creature that has somehow found its way into the orphanage. For example, a house - elf might be there, either sent by someone to protect Harry or just lost. This house - elf could be a key character in the story, helping Harry with small tasks and providing some comic relief. There may also be a character from the Ministry of Magic who is sent to check on Harry's well - being in the orphanage, and this person could have their own motives and secrets.
Well, Hermione is often depicted in different ways in these fanfics. In some alternate universes, she could be a powerful dark witch instead of the studious and good - hearted character we know. Ron might be a super - confident and arrogant character rather than the sometimes insecure boy in the original story. Also, Snape could be a completely different person. He could be a jolly and friendly teacher rather than the brooding and complex one we are used to.
Severus Snape is a fan favorite in alternate universe stories. People are interested in seeing his character developed further, perhaps in a world where he didn't have such a complex relationship with Lily Potter. Harry Potter himself is, of course, a popular choice. Fanfic writers might create scenarios where Harry discovers his magic much earlier or has different adventures outside of Hogwarts that change his character development.
Hermione would likely be there. She's Harry's best friend and would not let him be in juvie alone. She'd probably be trying to find a way to get him out legally, researching all the laws and loopholes. Ron might also show up, being another one of Harry's closest friends. He could be the more impulsive one, thinking about breaking Harry out rather than going through the proper channels. Dumbledore might also be involved in some way. He has always been a guiding figure for Harry, so he could be working behind the scenes to ensure Harry's safety and find a way to clear his name.
Tom Riddle (before he became Voldemort) is a popular character to explore in alternate universes. Writers can delve into his early years, his time at Hogwarts, and what could have been different to prevent him from turning into the Dark Lord. Also, the Weasley twins are often used in fanfiction. Their prank - loving nature can be used to create all kinds of chaos and humor in different universes.
One interesting plot could be that Harry Potter is sent to an alternate universe where magic is used in a completely different way. For example, instead of using wands, they use hand gestures. Another plot might be that in the alternate universe, Voldemort won in the original world, and Harry has to find a way to reverse that in this new universe. Maybe in this alternate world, the Hogwarts houses have different characteristics and he has to adapt to that new social structure as well.
Hermione could still be a common character. Even in fanfiction where Harry is alone, Hermione might be mentioned in his thoughts or in flashbacks as someone who has influenced him. For example, he might recall her advice on how to study magic when he is facing a difficult spell alone.
Yes, there's a fanfic called 'Harry in the Alternate Realm'. In this story, Harry is suddenly thrust into an alternate universe where the Hogwarts houses have different values and the magic is a bit more primal. It's fascinating to see how Harry adapts to this new environment.
Often, Harry Potter himself still makes an appearance in these fanfictions. He might visit the alternate school for some special event or competition. Hermione Granger could also be there, perhaps as a guest lecturer sharing her vast knowledge. Ron Weasley may tag along with Harry. And of course, Dumbledore might be a figure that is mentioned or even has some influence over the alternate school, given his great wisdom and power in the original series.
Ron could also be there. He might be initially scared of the dragon but then grows to like it. His loyalty to Harry would make him support Harry's decisions regarding the dragon, even if they seem risky. For example, when they need to hide the dragon from the Ministry of Magic, Ron would be right there with Harry, coming up with crazy but effective plans.
