Who would be the most interesting characters in a 'Harry Potter raises Tsuna' fanfiction besides Harry and Tsuna?

One possibility could be that Harry, with his knowledge of magic and experience in fighting dark forces, takes Tsuna under his wing in the magical world. He could teach Tsuna about different spells and how to handle magical creatures, which would be a new and exciting experience for Tsuna who is used to his own world in 'Katekyo Hitman Reborn!'.

In some fanfictions, the idea of Tsuna and Harry Potter swapping places is really fascinating. They have to adapt to each other's worlds and learn new ways of using magic. It shows how different yet similar their two worlds are in terms of magic systems and challenges.

Well, for Harry, he'd develop a deeper understanding of different kinds of magic and people. Since Tsuna comes from a different background, Harry would have to adapt his teaching methods. This would make him more flexible. Tsuna would start to develop a more adventurous spirit. He'd be more willing to take risks as he sees Harry's courage. Also, in terms of their relationship, they'd go from being strangers to a family - like unit. Tsuna would look up to Harry, and Harry would feel a need to protect Tsuna at all costs. This would shape their personalities in different ways, with Harry becoming more protective and Tsuna more trusting.

Reborn is often involved. Since he is Tsuna's mentor, he could play a crucial role in guiding Tsuna during his time - traveling adventures. Maybe he has some knowledge about time travel that he imparts to Tsuna.

The main characters are Harry and Tsuna. Harry, who has a complex past and a strong sense of justice, decides to take Tsuna into his care. Tsuna, on the other hand, is a character with his own unique personality. He is not very confident initially but has hidden strength. Along with them, we might also see other characters like Dumbledore in Harry's world, who could support Harry in his decision to adopt Tsuna, and characters from Tsuna's family and friends circle who could react to this new situation.

One interesting storyline could be how Harry Potter's experiences with death and his mastery of it influence Tsuna in a new magical world that combines the universes. Maybe Harry teaches Tsuna some of his unique magical skills related to death, like communicating with the dead, which could be used in Tsuna's battles against his own foes.

Hermione would be really interesting. Her thirst for knowledge would make her eager to learn from Bilbo's tales and experiences. She could also help Bilbo understand the complex magic of the wizarding world. Another great character would be Gandalf. If he somehow made his way into the wizarding world, he could offer his wisdom and guidance. And of course, Ron. His loyalty and sense of humor could provide some great comedic moments and also a strong friendship with Bilbo.

Well, perhaps in this fanfiction, Harry, now Tsuna, has visions of his past life at Hogwarts during his battles in the KHR world. These visions give him an edge as he can draw on the spells and strategies he used against Voldemort to fight his new enemies. Also, his relationship with Reborn could be really interesting. Reborn might be intrigued by Tsuna's strange bursts of knowledge and skills that seem to come out of nowhere, which are actually remnants of Harry's past magical training.

Yes, there are some really interesting 'Harry is Tsuna' fanfictions out there. You can often find them on popular fanfiction websites. Some explore unique crossovers between the two characters' worlds, like how Harry's magic might interact with Tsuna's abilities in the world of 'Katekyo Hitman Reborn!'.

One challenge could be the differences in the settings. Harry Potter has a very distinct wizarding world with its own rules and institutions like Hogwarts, while Tsuna has his own world with different power systems. Blending these two settings in a believable way is no easy feat.
