What are some of the most interesting plot developments in fanfiction where Naruto can control all the elements?

One interesting application is his ability to create entirely new jutsus by combining different elements. For instance, he could mix fire and wind to create a super - heated blast that's more powerful than either element alone.

One interesting plot development could be Izuku using his new control over One for All to quickly master new quirks within it. He might surprise his classmates and teachers with his rapid progress in combat training.

One interesting plot development could be Naruto using his time - control ability to prevent the death of his parents. He might go back in time and change the events that led to their demise, thus altering the whole Naruto universe as we know it.

One interesting plot development could be Naruto having to deal with the Uchiha clan's history and secrets that come with the Sharingan. He might have to face the Curse of Hatred that the Uchiha are known for. Another aspect could be his relationship with Sasuke changing. Since Naruto now has a part of what makes Sasuke special, it could create a new dynamic between them, either one of rivalry or cooperation in a different way.

One interesting plot development could be Naruto's unique fighting style integrating with the peerage's combat strategies. His shadow clone jutsu, for example, could be used in new and creative ways during battles against other supernatural groups. It might also lead to some comical moments as Naruto tries to adjust to the more formal and sometimes strict rules within Rias' peerage.

One challenge could be the sheer amount of chakra it requires. Controlling all elements might demand a vast amount of chakra, and Naruto may find himself quickly drained in battles. For example, if he tries to use all elements simultaneously, he could run out of chakra and be left vulnerable.

Well, it could completely reshape the battles. Instead of relying on just one or two main elements like wind in the original, he can now use a combination of all elements to outwit his opponents. For example, he could use water to douse an enemy's fire jutsu and then follow up with earth to trap them.

In certain fanfiction scenarios, it could be through some kind of ancient training method that was long forgotten. Naruto stumbles upon an old scroll or meets an old hermit who reveals to him the secrets of controlling all elements. So, his discovery is more of a guided, knowledge - based awakening rather than a spontaneous one.

One possible plot development could be that Naruto uses his new - found control of the Nine - Tails to defeat a powerful enemy that was previously unbeatable. He might be able to combine his own ninja skills with the Nine - Tails' power in a more efficient way, like creating new and unique jutsu.

Perhaps Naruto uses Kushina's memories to better understand the political landscape of the village in the past. This knowledge could help him to navigate current political issues in the village more effectively. He could use the wisdom from her memories to make changes or prevent past mistakes from repeating, which would be a very engaging plot development.
