Well, in this fanfiction, it could be that Harry Potter has come across some sort of ancient magic or artifact that has changed him. Maybe this magic has a connection to Tobi's essence or the type of power that Tobi wields. Additionally, he might be trying to protect his friends in a different way. Tobi has his own way of safeguarding what he holds dear, which might seem appealing to Harry in a difficult situation. Or, there could be a prophecy or a hidden message that he has misinterpreted, leading him to believe that acting like Tobi is the right path to take.
In the 'harry potter acts like tobi fanfiction', Harry Potter's behavior could change in several ways. Tobi is known for his ability to manipulate situations to his advantage. So, Harry might start using his knowledge and skills in a more calculating way. For example, he could be more strategic in his interactions with his friends and enemies alike. Instead of being straightforward, he might play mind games like Tobi does. He could also become more solitary, as Tobi often keeps to himself, and only reveals his true intentions when it suits him. This would be a significant departure from Harry's more open and honest nature in the original series.
One way could be to give Harry a more mysterious and aloof side like Tobi. Maybe he starts using illusions or misdirection in battles at Hogwarts, similar to how Tobi uses his Sharingan abilities. He could also adopt Tobi's habit of speaking in riddles, making his classmates and teachers wonder what he's really thinking.
Maybe he's on a secret mission. He could be trying to infiltrate an enemy group that Tobi was associated with. By acting like Tobi, he hopes to gain their trust and gather information.
Another theme is often the discovery of new magic or secrets. Since Tobi is an outsider in a way, he might stumble upon things that the regular Harry Potter characters haven't. This could be a hidden spell, a lost artifact, or a secret chamber. And this discovery then drives the plot forward as he has to deal with the consequences of it.
If Harry Potter started acting like Tobi Uchiha, it would change his relationships completely. His friends would be confused and probably a bit hurt. Hermione, being the logical one, would try to figure out what was wrong with him. Ron might feel betrayed. In battles, Harry could use tactics similar to Tobi. Instead of straightforward dueling, he might use distractions and illusions, which would be a new and unexpected approach in the wizarding world, throwing his opponents off guard.
There is a fanfiction titled 'Tobi and the Forbidden Magic'. In this story, Tobi discovers a long - forgotten magic in the Harry Potter universe. It delves into how he tries to master this magic while also dealing with the suspicions of the Hogwarts faculty. It's a story full of mystery and intrigue as Tobi has to keep his discovery a secret from those who might not understand.
Well, perhaps in this fanfiction, when Harry Potter wears Tobi's mask, he gains some of Tobi's mysterious powers. He could use these powers to secretly spy on the Death Eaters, getting valuable information to help the Order of the Phoenix. Maybe the mask also gives him a new look that confuses his enemies, and he uses this to his advantage in battles.
Well, it could be really exciting. Maybe Harry would have some of Tobi's memories or skills. He might use Tobi's combat knowledge in the wizarding world. For instance, if Tobi was a great fighter in his previous life, Harry could suddenly be more proficient in dueling.
One possible plot development could be that Harry begins to undermine the existing power structures at Hogwarts. He might start by sowing seeds of doubt among the students and teachers, just like Aizen did in his own world. Another could be that he forms a secret group of followers who are loyal to him and his new ideals.
Perhaps Harry would try to take over Hogwarts in a more forceful and underhanded way. He might try to oust Dumbledore or other authority figures, using his new - found 'Scar - like' traits. He could also form an unlikely alliance with some of the dark wizards or creatures, thinking that they can help him achieve his power - hungry goals. For example, he might team up with some of the Death Eaters who are still lurking around, which would be a huge shock to the wizarding world.
