One popular storyline could be Dark Naruto and Mikoto teaming up to face a common enemy. Maybe an ancient evil that threatens the Hidden Leaf. They combine their unique skills, Naruto's dark powers and Mikoto's Uchiha abilities.
Some fanfictions focus on the idea of Naruto being adopted by the Uchiha family. In this scenario, Mikoto becomes his mother figure. They might have heart - to - heart conversations about Naruto's loneliness and Mikoto's concerns for her family. Also, there could be a plot where Naruto's positive influence on Sasuke starts earlier because of his relationship with Mikoto, and this changes the whole dynamic between Naruto and Sasuke in a positive way.
A third storyline could involve a mission where Kushina, Mikoto and an older Naruto have to work together. Maybe there's a threat that only the combination of Uzumaki and Uchiha powers, along with Naruto's experience, can defeat. During the mission, they could face various challenges that force them to rely on each other. Kushina could show her strong - willed and feisty side, Mikoto her intelligence and grace, and Naruto his leadership skills. This would be a great way to explore their characters in a new context.
One interesting storyline could be a time - travel fanfic where Naruto goes back in time and meets a young Mikoto and Kushina. He could use his knowledge from the future to prevent certain tragedies from happening to their families. For example, he might try to stop the Uchiha massacre by changing the events that led to it. Another could be a story where Mikoto and Kushina become friends and train together, and Naruto somehow gets involved in their training sessions, learning new skills from them. Maybe they discover a new jutsu together that changes the course of the ninja world.

In some fanfictions, a popular storyline is Dark Naruto using Lightning Style to exact revenge. He might target those who wronged him or Konoha in his view. He could use his Lightning Style in really creative and unexpected ways, like combining it with genjutsu to create illusions of lightning strikes that are actually traps. This makes for an exciting and action - packed read.
One popular storyline could be where Dark Naruto and Hana team up against a common enemy. Their unique abilities combined make for an interesting dynamic in battle.

And then there are also fanfictions that focus on their potential romantic relationship, showing how they might fall in love despite their differences.
One popular storyline is where Harry, in his 'dark' state, teams up with Luna to uncover a hidden conspiracy within the wizarding world. They might face off against a powerful dark force that has infiltrated Hogwarts or the Ministry. Another is a more angsty plot where Dark Harry has some internal conflict and Luna is the only one who can reach his true self. For example, she might use her unique understanding of the magical world to show him a different path.
One popular storyline is the 'What if' scenarios. For example, what if Naruto had a different upbringing. Maybe he was raised by a different ninja or outside of Konoha. Another is the exploration of new jutsu creation. Fanfic writers often come up with unique jutsu for Naruto or his friends. Also, the idea of Naruto having different relationships, like a more in - depth friendship with Sasuke that goes beyond the canon, is quite common.
