One possible plot could be that Harry starts to have strange dreams and visions which are actually Obito's memories. He begins to question his own identity and purpose. As he delves deeper into these memories, he might discover new magical abilities or ways of thinking that are influenced by Obito's ninja world experiences. This could lead him to form new alliances at Hogwarts and change the way he approaches the battle against Voldemort.
Sure. In this fanfiction, Harry could be raised in a world where ninjutsu is the norm. Since Obito has a rather tragic backstory, he might be overprotective of Harry. Harry could bring some of his own magic - like knowledge of spells - into the Naruto world, which would make for an interesting dynamic. He might also make friends with Naruto or Sasuke, and together they could face off against common enemies, with Harry having to balance his two very different heritages.
A possible plot could be that in a parallel dimension, Harry Potter is actually Obito Uchiha reincarnated. He is born into the wizarding world but still has some latent memories and powers from his past life as Obito. As he grows up in Hogwarts, he discovers his unique abilities which are a blend of magic and the powers of the Sharingan. He uses these to uncover a hidden conspiracy within the wizarding world that is related to an ancient dark magic that has similarities to the dark powers in Obito's original world. Along the way, he has to deal with his own inner demons, just like Obito did, and also face off against the traditional threats in the Harry Potter universe like Voldemort and his followers, but with a whole new set of skills and a different perspective due to his dual - natured identity.
A plot could be centered around Obito's past and how it parallels some of the characters in Harry Potter. For example, Obito's experience of loss and his turn to the dark side could be compared to Severus Snape's story. Obito could be drawn into the conflict between the Order of the Phoenix and the Death Eaters because of his own complex moral compass. He could use his knowledge of different jutsu to create new spells or counter - spells in the wizarding world, all while exploring his own redemption arc similar to some of the characters in Harry Potter.
One plot implication could be that Naruto is initially distrusted by some in the village. They might see the Sharingan as a symbol of danger or the Uchiha's past misdeeds. This could create internal conflict within the village. Also, Naruto might be hunted by enemies who fear the power of the Sharingan in his hands.
Maybe in the fanfiction, Snape watches Harry's memories in an attempt to find some hidden secrets. He could be looking for clues related to Harry's connection with Voldemort. As he delves deeper into the memories, he might start to understand Harry's courage and loyalty in a way he never did before.
Harry would likely become more cynical. Obito's experiences of betrayal and loss could make Harry less trusting. He might also become more secretive as he tries to figure out these new memories on his own.
One interesting plot point could be that Harry discovers a hidden agenda of Voldemort that was unknown to everyone. Maybe there was a part of Voldemort's plan that was so well - hidden that only by having his memories can Harry find out. This could lead to a new race against time to stop something that Voldemort had set in motion long ago.
One possible plot could be that Naruto uses Ashura's memories to unlock new powers. These powers could help him in battles against stronger enemies. For example, he might remember some ancient sealing jutsu from Ashura's time.
One possibility could be Naruto having to deal with Obito's past traumas and memories while trying to use his own ninja skills. He might struggle to convince Obito's old allies that he's not the same person. For example, he could have to face Kakashi and try to explain the situation without revealing too much of Obito's secrets.
Well, it could be about Kakashi finally finding Obito after a long search. Maybe Obito has changed a great deal, and Kakashi has to come to terms with this new version of his old friend. They might have a battle first due to their different paths, but then they start to talk and remember their past together, like their time as teammates in Team Minato.
