A 'naruto all elements fanfic' could center around Naruto being cursed with an imbalance of all the elements within him. He has to find a way to control and harmonize them, perhaps with the help of an ancient sage who once mastered all elements. This could lead to new and powerful jutsu development.
Perhaps in the fanfic, the One for All quirk could be linked to Naruto's Nine - Tails chakra. The two powerful forces could either clash or merge, creating a completely new power dynamic within Naruto. This could also cause internal struggles for Naruto as he tries to control both the wild nature of the Nine - Tails and the unique properties of One for All.
One idea could be exploring a new elemental power that combines two existing ones in the Naruto universe, like Fire and Wind to create a super - hot tornado - like jutsu. Another could be a fanfic where a character has an elemental power that is usually rare, such as lightning water, which is a combination of lightning and water elements. You could also write about a fanfic where the main character discovers a lost elemental art that was once used by a powerful clan long ago.
One plot idea could be a character from the All for One world somehow ending up in the Naruto universe and having to adapt to the chakra system. Maybe they try to steal chakra powers like they steal quirks in their own world.
One idea could be a time - travel fanfic where Naruto or Sasuke go back in time and try to change certain events. This would allow for a lot of creative storytelling as they interact with their younger selves and try to prevent future tragedies.
One idea could be to create an alternate universe where Naruto has a different elemental affinity from the start. For example, instead of wind, he has lightning. Another could be a fanfic focused on the relationships between the characters outside of the main plot, like how Sakura and Ino rekindle their friendship in a more in - depth way. Or you could write about Naruto's training journey with a different mentor, say Jiraiya's long - lost brother who has a completely different teaching style.
One idea could be a fanfic where Naruto travels to a different dimension where the Akatsuki are the heroes. Another could be a story about Naruto's kids growing up in a world where there's a new threat that they have to face without their parents' immediate help.

One idea could be a time - travel fanfic where Naruto travels back in time to when he was a baby.

Another idea is a story where Naruto's friends find an old photo of him as a baby in a diaper and they all have a good laugh about it and then it leads to sharing stories about their own childhoods.
One plot idea could be that Naruto, with his masochist tendencies, volunteers for Anko's extremely tough training regime. Anko is initially puzzled by Naruto's eagerness to endure such harsh training but soon realizes that it's part of his unique personality. As they train together, they start to understand each other better and form a strong bond of friendship. Naruto's masochist nature actually helps him progress faster in the training, and Anko begins to respect his determination.
