In such a fanfiction, apart from Harry, there could be a gang of street urchins. One of them might be a girl who has a special connection with Harry. And then there are the professors at Hogwarts. Snape would probably have an even more difficult time with this street - raised Harry. He might see him as a troublemaker at first. And Dumbledore would be the one trying to guide Harry in this new, different situation, still seeing his potential.
Well, for sure Harry is the main character. There could be a mean street vendor who harasses Harry. In the wizarding world, Sirius Black could have an interesting role. He might be more of a kindred spirit to Harry, having been on the run and living a rough life himself. And the Weasley family would be a contrast to Harry's street - upbringing. Their warm and family - oriented nature could either draw Harry in or make him feel out of place.
Obviously, Harry Potter himself. Then there could be a Texan version of Hagrid, like a big - hearted rancher who discovers Harry's magical abilities. There might also be a local witch or wizard who acts as a mentor, someone with a thick Texan accent. And don't forget about the muggles in Texas, Harry's classmates at a regular school before he goes to Hogwarts. They could be curious, tough - as - nails Texans who don't quite understand Harry's strange behavior at times.
Obviously, Harry himself. Then there could be German - born wizards and witches who become his friends or mentors. There might be a strict German potions master like Snape in Hogwarts. And perhaps a German - version of Dumbledore, an old and wise wizard who guides Harry.
Obviously, Harry Potter himself. Then there could be some Canadian - born witches and wizards as his friends. Maybe a tough - as - nails girl from the Yukon who is an expert at ice magic. And a laid - back boy from Vancouver who has a special talent for communicating with magical forest animals.
A 'Harry Potter raised in streets' fanfiction would show a very different side of Harry. He might not be as well - mannered as in the original story. Growing up on the streets would make him more resourceful. He could have formed alliances with other street kids, some of whom might be magical too. When he gets to Hogwarts, his values would clash with the more sheltered students. He may also be more attuned to the darker aspects of magic, having seen the worst of the Muggle world. His wand - work could be more instinctual, developed from his need to protect himself in the streets.
In such a fanfiction, Harry might form different relationships. Instead of the friends he made at Hogwarts right away, he could meet other outcasts on the streets. These could be either magical or non - magical beings. His view of the wizarding world could be more jaded as he's had a rougher start, and he might be more distrustful when he finally enters Hogwarts.
Well, aside from Voldemort, there might be corrupt elements within the assassin organization that raised Harry. They could see his magic as a threat to their power and secrecy. Also, there could be some dark wizards who team up with the assassin enemies of Harry. These villains would be more complex as they combine the danger of dark magic with the stealth and combat skills of assassins. And there could be a new character, perhaps an assassin who was once a friend but turns bad due to jealousy or a thirst for power, creating a more personal and dangerous threat to Harry.
Voldemort would still be a major enemy. But with Kratos raising Harry, Voldemort might face a much more challenging opponent. Also, any dark wizards or creatures that oppose Harry would be in trouble. Kratos wouldn't tolerate any threats to Harry, so even the Death Eaters would have to be extra careful. Another potential enemy could be those in the wizarding world who oppose Kratos' methods of raising Harry, seeing them as too brutal or un - wizard - like.
Some of the Death Eaters who might have survived or changed their ways in an alternate universe could be the slashers. They would bring their knowledge of the Dark Arts and their own twisted view of the wizarding world. Bellatrix Lestrange, if she had a different path, could be a very interesting slasher figure in such a fanfiction, as she is extremely powerful and unpredictable.
Maybe there is a social worker named Mrs. Johnson who is trying to help the homeless in the area. She tries to reach out to Percy, but he is initially hesitant because he has trust issues. These characters can all interact with Percy and shape his story while he lives on the streets.
Since it's a fanfiction, it could vary. But surely Harry Potter would be one of the main characters. There might also be some original characters created by the author, like a street - wise wizard who befriends Harry and shows him the ropes of the wizarding streets.
