One of the popular characters is Orochimaru. He was always interested in forbidden jutsu and seals in the original Naruto, so in fanfic he can be the center of many seal - related plots. He might be creating new and dangerous seals or trying to steal ancient seal knowledge. Another character is Tsunade. Given her status as a Sannin and her own unique abilities, fanfic writers can incorporate her into seal - related stories. For example, she could use her superhuman strength in combination with a seal to create a powerful attack. And Itachi is also often involved. His Mangekyou Sharingan abilities and his mysterious nature can be intertwined with seal concepts in very interesting ways.
Naruto himself is often involved in Naruto seals fanfic. Since he's the main character in the original series, writers like to explore his potential with seals further. Sasuke is also a popular choice. His Uchiha heritage and his own power - hungry nature make for interesting stories when combined with seal knowledge. Kakashi is another one. His Sharingan and his vast knowledge of jutsu could lead to some really creative seal - related scenarios. And of course, Jiraiya, as he was a master of many things including seals, and his relationship with Naruto can be further developed in fanfic with a focus on seals.
Sakura is frequently involved in Naruto seals fanfic. Although she was mainly known for her medical ninjutsu in the original, in fanfic she might discover a new talent for seals and use it to enhance her combat abilities. Shikamaru, with his high intelligence, is also a popular character in these fanfics. He could use his strategic mind to develop new seal techniques or figure out complex seal puzzles. Additionally, Hinata is often included. Her Byakugan could potentially be used in conjunction with seals in ways that are not explored in the original, like using the Byakugan to analyze and replicate seals more accurately.
Sakura is another character that can be involved. Her strength and medical ninjutsu skills can be combined with other offensive or defensive jutsus. For instance, fusing her superhuman strength punch with a genjutsu to create a more complex and powerful attack. Her growth as a character throughout the series also gives room for different fusion jutsu ideas in fanfics.
Sasuke can also be involved. His intelligence in combat and his knowledge of various jutsu make him a great addition to a fanfic centered around intelligence. He and Naruto can have intellectual battles or work together to face a greater threat.
Naruto himself is obviously very popular in these fanfictions as the main character. His decisions are the central focus. Sasuke is also commonly involved. Since Sasuke's actions and decisions often intertwine with Naruto's, fanfiction writers like to explore how different decisions from Naruto would affect Sasuke's path. For example, if Naruto made a decision that could sway Sasuke from his revenge - seeking journey.
Naruto is often involved. Since he has the ability to transform into the Nine - Tails in the original series, fanfiction might expand on this by giving him more shapeshifting abilities or different forms of the Nine - Tails transformation. For example, a more powerful and controlled version of the full - Nine - Tails form.
Sasuke is often involved. His powerful chakra and skills make him a natural fit for stories involving barriers. He could be trying to break through a powerful barrier or using his Sharingan to analyze and then counter a barrier technique. Naruto is also popular. His large chakra reserves could be used to power up or break barriers in unique ways.
Kakashi is another character that frequently shows up. His experience and cool - headedness make him a great character for a reborn character to interact with. The reborn character could learn from Kakashi or even teach him something new, creating an engaging relationship within the fanfiction story.
Naruto himself is often involved. Since Gear 4 is a power - up concept, it makes sense for Naruto, with his never - give - up attitude and strong chakra reserves, to be the one to either use or face Gear 4. He could potentially learn to incorporate it into his Rasengan techniques.
Naruto himself is often involved. Imagine Naruto henged into a powerful ancient sage form that no one has ever seen before. It would create a whole new set of adventures for him.
Obviously Naruto is often a main character in 'Naruto Crystal Fanfic' as it is related to the Naruto universe. Sasuke can also be involved, perhaps having a different view on the power of the crystal compared to Naruto.
Sasuke is often a main character in 'eye naruto fanfic'. Since he has the Sharingan, many fanfics explore different aspects of his eye power, like how he might develop it further or use it in new and unexpected ways. Another one is Hinata. With her Byakugan, fanfic writers can create stories about her using it in battles or for some other special purposes, like finding hidden secrets in the ninja world.
