How does the concept of 'Harry Potter deaged' in fanfiction usually work?

In 'deaged Naruto fanfiction', usually Naruto is somehow magically or through some strange jutsu deaged. For example, he could be turned into a baby or a young child. Then the story explores how he copes with this new state.

The concept usually works in a way that the life debt can't be easily dismissed. It's like a magical contract. For example, if a character saves Harry from a deadly curse, Harry might find himself having to help that character in their own personal quests. This could range from something as simple as retrieving an item for them to getting involved in more dangerous and complex situations like facing off against a dark wizard that the character has a vendetta against.

Another way the 'Harry Potter is summoned' concept works is when a magical being with great power summons him. This could be a powerful wizard from another land or a magical creature like a phoenix or a centaur. They might summon Harry because they sense his unique magic or because they believe he has the ability to solve a problem that they can't. For example, a centaur might summon Harry to help deal with a dark magic that is corrupting the forest it guards.

In 'My Little Pony Deaged Fanfiction', deaging often works through magical means. It could be a spell gone wrong, like a young unicorn accidentally casting a deaging spell instead of a growth - enhancing one. Or it might be a result of some ancient, forgotten magic being unleashed in Equestria.

In fanfiction, the 'Harry Potter and Hedwig love' concept often works by expanding on the deep emotional bond they already have in the original series. Writers might give Hedwig more human - like qualities, such as the ability to understand complex human emotions. This allows for a more equal relationship between her and Harry.

Often, it's through some new form of magic. Maybe a spell or a potion gives him this ability.

The Thestral as a familiar in fanfiction often means it has a special connection with the wizard or witch. It can act as a guide, leading the character through dangerous places like the Forbidden Forest.

In Harry Potter fanfiction, a powerful harem often means that Harry is surrounded by strong female characters. These characters might have strong magical abilities, like being able to perform complex spells or having unique magical gifts. They support Harry in different ways, be it in battles or in his personal growth.

The concept often involves some sort of magical anomaly. Maybe a magical artifact malfunctions and sucks in Harry's magic, then transfers it elsewhere. Sometimes, it's a connection between two characters. For instance, if there's a deep emotional bond between Harry and another character, and that character is in a life - threatening situation, Harry's magic might transfer to them to save their life. It can also be a part of an experiment in a fanfiction where wizards are trying to understand the limits and transferability of magic, and Harry becomes an unwilling subject.

Well, it could be that a spell goes wrong. In the fanfiction world, spells can have all sorts of unexpected consequences. So a spell that Harry or someone else casts accidentally combines with some ancient magic that has a connection to the Rinnegan. This causes the Rinnegan to manifest in Harry. Another way could be that Harry discovers an ancient artifact in the wizarding world that has some sort of link to the Naruto universe, and when he touches it, he gets the Rinnegan. This then sets off a whole new adventure for him as he has to learn to control this new power.
