A possible plot twist could be that Harry's ability to learn bending is actually a result of a long - lost family connection. His ancestors were from a world where bending was common, and this latent ability surfaces in him. However, this connection also reveals a whole new set of enemies who are after him not just because of his role in the wizarding world, but also because of his new - found bending skills.
One possible plot twist could be that Naruto has a really hard time controlling the Chidori at first. Since his chakra nature is different from Sasuke's who originally used Chidori. He might accidentally release too much chakra and the Chidori becomes a much larger and more uncontrollable form, causing chaos during his training sessions. Another twist could be that when Naruto finally masters it, it takes on a unique form because of his Uzumaki chakra. It might have some kind of sealing ability added to it, which is different from the traditional Chidori.
Maybe he turns into a cat because of a misfired spell from a young, inexperienced wizard. And while in cat form, he finds that he can communicate with the magical cats around Hogwarts in a way he couldn't as a human. They tell him secrets about the Forbidden Forest that could help in protecting the school.
One possible plot twist could be that Harry, as James' brother, has a different role in the fight against Voldemort. Maybe he's more of a behind - the - scenes strategist. Since he's in the family earlier, he could have different relationships with the other characters too. For example, his bond with Sirius might be even stronger as they grow up together more closely.
One possible plot twist could be that Kenpachi's rough and battle - hungry nature makes Harry a much more aggressive wizard. Instead of waiting for Voldemort to come to him, Harry might actively seek out dark wizards to fight. Another twist could be in the way magic is taught. Kenpachi, not being from the wizarding world, might introduce Harry to a more physical and unorthodox way of using magic, like using brute force in spellcasting rather than the traditional finesse. Maybe Harry would also develop a more carefree attitude towards the rules of the wizarding world, much like Kenpachi does with the Soul Society's rules.
One possible plot twist could be that Harry Dresden's magic system clashes with the wizarding world of Harry Potter. For example, Dresden's more rough - and - tumble approach to magic might get him in trouble with the Ministry of Magic. Another could be that Harry Potter, being raised by Dresden, develops a very different personality. He might be more street - smart and less naive compared to his original self. Also, there could be a plot twist where the enemies from Dresden's world start targeting Harry Potter because of his connection to Dresden.
In this fanfiction, a plot twist could be that Naruto's learning of Hiraishin and Rasengan is somehow linked to the Akatsuki's plans. They might be secretly manipulating events to make Naruto learn these techniques, with the intention of using him as a weapon or a decoy.

One possible plot twist could be that Naruto has a really hard time controlling the Lightning Armor at first. Instead of it enhancing his speed and power, it causes him to accidentally electrocute his friends.

A great plot twist could be that the explosion alchemy Naruto learns is actually a corrupted form. As he tries to master it, he starts to lose control of his chakra and his mind. He has to fight against the dark influence of this false alchemy while also trying to find the true and pure form of it. This internal struggle could be a major part of the fanfiction.
A really cool plot twist could be that the Hiraishin no Jutsu is linked to Naruto's Uzumaki heritage in a way that no one expected. For example, the jutsu was originally developed by an ancient Uzumaki clan member, and Naruto's latent Uzumaki powers are the key to unlocking its full potential. So, instead of just learning it like any other jutsu, he has to dig deep into his family's history and powers to truly master it. This would add a whole new layer to his journey and his connection to his clan.
One possible plot twist could be that Naruto initially struggles a great deal with Shiki Fujin. Maybe he accidentally activates it in a wrong way and it starts to drain his chakra in an uncontrollable manner. This could lead to a situation where his friends have to step in to save him, and in the process, he discovers a new way to control the jutsu.
