In this fanfiction where Harry is deaged to three, there would be significant changes in his relationships. His relationship with Hermione and Ron would be completely different. Instead of being their equal in age and experience, he'd be like a little toddler they need to look after. Hermione might take on a motherly role, trying to teach him basic things. Ron could be the one who tries to make him laugh with silly jokes. And the whole Hogwarts community would have to adapt to having a three - year - old with a great destiny in their midst. There would be concerns about how Voldemort or his followers might try to take advantage of his weakened state as a child.
One common theme is the rediscovery of innocence. When Harry is deaged, he gets to experience the magic world anew, without the heavy burdens he had as a teenager. For example, in many such fanfics, he's excited about simple spells again.
Hermione and Ron would most likely be main characters. They are Harry's closest friends in the original story. Since Harry is deaged, they would play important roles in taking care of him or guiding him in some way.
In some fanfictions, Harry Potter might discover a hidden magical object in the bathroom. For example, a secret passage could be revealed behind a mirror or a sink when he's in there alone, leading him to a new adventure or a place filled with ancient magic.
Well, Harry could get involved in some really off - the - wall pranks. Since he's bored, he might decide to play some elaborate tricks on his friends, like magically changing their voices during class.
In fanfiction, if Harry Potter disappears, it could lead to chaos at Hogwarts. His friends like Hermione and Ron would likely be on a desperate search for him. They might suspect the Dark forces at work again, and start investigating all the possible places where Harry could have been taken or hidden.
In fanfiction, Harry Potter could be wrongly accused of using dark magic in court. Maybe some false evidence is presented against him, like a planted dark magic item. And he has to fight to prove his innocence.
Well, it could be a meeting between Harry and some long - lost relative. Maybe a wizard from a far - off land who has a connection to his family. It could bring new revelations about his past and powers.
In fanfiction, the possibilities are endless. It could be that they go on an adventure to a previously unknown magical land or face a powerful dark wizard who was thought to be defeated.
Well, it could go in many directions. They might travel to a previously unknown magical realm or encounter creatures that were only hinted at in the original series.
Another theme is the exploration of nature vs. nurture. Fans wonder if a de - aged Tom, when placed in a different environment, will still grow up to be the evil Voldemort. This leads to stories where he is raised by different families or groups in the wizarding world, and we see how his character develops.
