Maybe in the fanfiction, the Lightning Armor has a hidden ability. Naruto discovers that when he combines it with his shadow clones in a certain way, he can create a massive electrical storm. He could use this to defeat a powerful enemy that was thought to be unbeatable. It would be a cool and unexpected development in the story.
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. This would create a lot of tension and drama as he has to figure out how to master it without hurting those around him.
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.
One possible plot twist could be that while wearing the Madara armor, Naruto gains some of Madara's combat skills and memories. This makes him question his own identity and purpose. He might start to see things from Madara's perspective, which could lead to conflicts within his team as they don't understand his sudden changes.
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. Naruto then has to figure out their scheme while still trying to master the techniques, adding a whole new layer of drama and conflict to the story.
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.
One possible plot twist could be that Naruto's early mastery of the Rasengan catches the attention of Orochimaru much earlier. Orochimaru might see Naruto as a more immediate threat or a potential vessel with even greater potential than before. This could lead to more direct and dangerous attacks on Naruto, forcing him to grow even faster in his combat skills and strategic thinking.
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 idea could be Naruto discovers an ancient scroll that details the secrets of the black lightning armor and he has to train in isolation to master it. This could lead to him developing new techniques related to the armor.
Well, the plot could involve Naruto coming across a powerful being from the Dragon Ball universe who decides to teach him the Kamehameha. Naruto, being the eager learner he is, starts practicing it. He might struggle at first because the chakra control required for the Kamehameha is different from his normal jutsu. But as he trains more, he gradually gets better. He could then use this new skill in a big battle against a common enemy, surprising his friends and foes alike.
