It could also be that an existing character from the Harry Potter series discovers or develops this new power. Maybe Hermione, with her brilliant mind, somehow unlocks this ability and has to deal with the consequences. She would have to balance her new power with her existing knowledge and friendships.
There could be a new villain in the fanfic who has the 'master of the mind' ability. This villain could be causing chaos in the wizarding world by manipulating the minds of important people. The main characters then have to figure out how to stop this powerful foe and save the wizarding world from their control.
Since I haven't read it, I can't say for sure. But it could be the main trio - Harry, Hermione, and Ron. They are often central to most Harry Potter fanfics as they are the main characters in the original series. Their minds are constantly evolving throughout the books, so it would make sense if they were the main characters in this fanfic too, especially if the focus is on a 'well - groomed mind'.
It depends on the specific fanfic. But it could be Harry Potter himself in a new role as a puppet master - like figure. Or perhaps a new character created by the fanfic author who has the powers of a puppet master and interacts with the well - known Harry Potter characters.
Harry Potter would likely still be a main character. Since it's related to the Harry Potter universe, his journey and how his mind is affected would probably be a central focus.
Ron Weasley often appears in these fanfics too. His loyalty and friendship with Harry provide a great backdrop for stories involving mind - reading. For example, if Harry could read Ron's mind, it could lead to some comical or heart - warming moments as Harry discovers just how much Ron truly cares for him. Dumbledore is also a frequent character. His wisdom and mysterious nature fit well into the concept of mind - reading. He could be guiding a character with the power, or perhaps even have the power himself in some interpretations.
Obviously, Harry Potter is the main character as it's centered around him being the Immortal Master of Death. He would be a more powerful and perhaps more complex version of himself from the original series.
One interesting concept could be the exploration of new magical abilities. Maybe the main character has a unique way of controlling minds that goes beyond what we see in the original Harry Potter series. For example, they can influence the thoughts of magical creatures as well as wizards.
In Harry Potter fanfic, characters can be deeply affected by the Mind Arts. For instance, if a character is subjected to Legilimency against their will, it could lead to a loss of privacy and a sense of violation. On the other hand, if a character masters Occlumency, it can give them a sense of power and control over their own mind.
Obviously, Harry is a main character as he is the one who is a Jedi master in this fanfic. There might also be his friends from Hogwarts like Hermione and Ron. They could be involved in Harry's Jedi adventures, either helping him or getting into trouble along with him.
Well, surely the illusion master would be one of the main characters. But there could also be some of the original Harry Potter characters like Harry, Hermione, and Ron. They might interact with the illusion master, either as friends or as people who are initially skeptical of this new form of magic.
Obviously, Harry Potter would be one of the main characters as it's in his name. He's likely to be the one with the power of the master of storms. Hermione Granger and Ron Weasley would probably also be important characters as they are Harry's closest friends and are often involved in his adventures in any Harry Potter - related story.
