Harry is probably very protective in this kind of fanfiction. He feels responsible for Tom's future, so he guards him closely. He is also patient, knowing that changing Tom won't be easy. Tom could be initially very reserved and a bit of a loner. He may be suspicious of Harry's motives at first, but as he experiences Harry's genuine care, he starts to open up and show more vulnerability.
Harry would likely be very determined and compassionate. He has seen the destruction Voldemort caused, and so he is determined to prevent Tom from going down that path. His compassion comes from his own difficult upbringing and he wants to give Tom a better chance. Tom, on the other hand, would be complex. He may start off with a sense of entitlement and a thirst for knowledge and power, but as he is exposed to Harry's love and different values, he begins to change.
Harry is likely to be his usual self - brave, kind - but also a bit more nurturing as he's adopting Sasuke. He would be patient in dealing with Sasuke's often cold and aloof exterior. Sasuke, on the other hand, would be his brooding self at first. He's full of vengeance in his original story, but in this fanfiction, he might start to let go of some of that as he experiences Harry's care and the new world of magic.
Arceus, being a god - like being, would probably be very calm and wise. However, in this fanfiction, as it has a relationship with Naruto, it might also show a more affectionate and protective side. It could be a bit aloof at times due to its divine nature, but still show deep care for Naruto.
Minerva would be a strict but loving mother - figure. She would be very protective of Hermione and would use her wisdom to guide Hermione in her magical studies and in life. She might be a bit more relaxed in her personal interactions with Hermione compared to how she is with students at Hogwarts.
Hermione would likely be a main supporting character. She could help Harry in coming up with ways to educate Tom and keep him on the right path. Also, Ron might be there, providing some comic relief and also acting as a sort of brother figure to Tom, showing him what a normal family - like friendship could be like.
Harry might have a more complex personality in this fanfiction. He may struggle between his loyalty to his old friends and his new life with Narcissa. His sense of right and wrong could be tested in different ways, for example, when dealing with Narcissa's former Death Eater connections. Narcissa would be a strong - willed character. She's used to getting what she wants in the pure - blood society. But with Harry, she has to learn to compromise and open up, which is a big change for her. And she would be constantly worried about how her actions will affect her family's reputation and safety.
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.
The main characters are Cedric and Harry. Cedric, a popular and talented student at Hogwarts, decides to take Harry under his wing. Harry, who has had a tough life so far, now has to adjust to living with Cedric. There could also be minor characters that are important for the story, such as Cedric's professors who might notice the change in Cedric's behavior due to his new responsibility of taking care of Harry, or Harry's enemies who might be more cautious now that Harry is under Cedric's protection.
The main characters are Harry and Ginny. Harry is the one who makes the decision to adopt Ginny. He is the more experienced and well - known wizard. Ginny, who has been through her own share of adventures at Hogwarts, now becomes Harry's adopted daughter. There might also be other supporting characters like Hermione and Ron, who could be involved in the story, either helping Harry with the adoption process or being there for Ginny during this new phase of her life.
The main characters are Gibbs, who is a no - nonsense kind of guy from the NCIS world, and Harry. Harry is not just a normal kid but a wizard with a past full of battles against evil. There could also be other supporting characters from the NCIS team, like DiNozzo, who might be initially skeptical about Harry's magic but later become friends with him.
The two main characters are obviously Harry and Severus. Harry, the hero of the wizarding world, who has a big heart and a sense of justice. And Severus, the complex and often misunderstood former Death Eater and potions master.
