One great theme is Naruto's training and how he overcomes various difficulties in his ninja training. For example, exploring his time with Jiraiya and how he hones his new skills.
Another interesting theme could be the relationships between the different ninja clans. How they interact, cooperate or sometimes have conflicts in the context of the Hidden Villages.
Also, fanfiction about Naruto's family, like his relationship with his parents in flashbacks or how he might start his own family in the future, would be a positive and appropriate theme for the Naruto fanfiction.
A great theme would be Naruto's relationships in a positive light. Such as his deepening friendship with his comrades like Sasuke and Sakura. Or perhaps his interactions with the new generation of ninja in the village, mentoring them and passing on his skills and values.
Some great topics would be Naruto's exploration of new jutsus. He could be on a journey to discover ancient ninja techniques that have been lost. Or, the story could focus on his family life, like how he raises his children to be strong and kind - hearted ninjas. Team - building adventures with his old friends and new comrades are also good topics.
One popular theme is the classic haunted house. There are many stories where people enter an old, dilapidated house and encounter strange noises, apparitions, and a sense of malevolent presence. For example, in 'The Haunting of Hill House', the characters experience a series of terrifying events within the spooky house.
Travel experiences are also great topics. We can talk about the different places we've visited, the local cultures we've experienced, and the amazing sights we've seen. It can be a beach in Bali or the ancient ruins in Rome.
There are many great topics. For example, you could have a fanfic about Naruto training in a new and unique way to master a new jutsu. This could explore his relationship with his mentors, like Jiraiya, during this training process.
Another positive theme could be Naruto's role as a leader. He could be leading a mission to help a neighboring village that is in trouble. This would show his leadership skills, his compassion, and how he uses his ninja abilities for good.
One positive theme could be Naruto and his friends going on a new adventure together to save a different part of the ninja world. They could face new enemies and develop new jutsu along the way.
Adventure themes are very popular. Writers might create new missions for the ninja teams, perhaps exploring uncharted areas in the Naruto world, facing new and powerful enemies, and how the characters develop their skills during these adventures. Another great theme is the redemption of characters. Some fanfics might focus on how a character who has made mistakes in the past tries to make up for it and find their place in the ninja world again.
Art is also a wonderful topic. We can talk about different forms of art such as painting, music and dance. For instance, discussing our favorite painters, the emotions that a piece of music can evoke, or the beauty of different dance styles.
Fanfiction that delves into Bella's artistic side could be really interesting. Maybe she discovers a passion for painting or writing, and the story could show how her creativity is influenced by her unique experiences. Also, fanfiction about Bella mentoring new vampires or werewolves in the ways of their respective worlds would be a cool concept. It would show her growth from a newbie to an experienced and respected figure in the supernatural community.
