Sasuke is often a character used as a guardian in fanfiction. His powerful skills and his connection to Naruto make him a likely candidate. He can use his sharingan to detect threats and protect Naruto from danger.
Kakashi could also be a common guardian in these fanfictions. He is Naruto's teacher and has a wide range of skills. He can use his copy - ninja abilities and his intelligence to safeguard Naruto.
Most fairy guardians in fanfiction are beautiful and ethereal. Their appearance is often described with delicate wings, glittering skin and bright, colorful eyes. They are also very intelligent and resourceful. When faced with a problem, they can come up with creative solutions. For instance, if they are outnumbered by enemies, they might use their knowledge of the local magic to create a diversion or a trap.
Well, Naruto himself is often a popular character in such fanfictions. His determination and his growth as a ninja make him a central figure. Sasuke can also be quite popular as he has his own complex backstory and his power is formidable. Among the 12 Guardians, the ones with the most unique abilities or the most tragic backstories tend to stand out. For example, if there is a Guardian who has the power to control time but at a great cost to himself, he might be a fan favorite.
It depends on the specific fanfiction. It could be Naruto and his friends taking on the role of eternal guardians. Or perhaps some new characters created by the author for this concept.
Most likely Naruto would be one of the main characters. Since it's a Naruto - based fanfiction, he'd probably be at the center of the story. And maybe some of the Guardians from 'Rise of the Guardians' would also be main characters, like Jack Frost.
Most likely Naruto would be one of the main characters. After all, it's in the Naruto universe. And then there would be the fairy guardians. They could be named characters with their own distinct personalities, like a headstrong fairy guardian or a wise old fairy guardian.
Other Naruto characters like Sasuke or Sakura might also be important. Sasuke could be involved in Naruto's new role as a 'guardian' either as a supporter or a skeptic. Sakura, with her medical skills, could play a role in helping Naruto in his 'guardian' - related adventures, perhaps by healing those affected by new threats that come with the combination of the two universes.
Obviously Naruto would be one of the main characters since he is the guardian. And there would probably be some Pokémon characters like Pikachu or Charizard that he interacts with.
Since there are many 'guardian of fire' Naruto fanfictions, the main characters can vary greatly. It could still have Naruto as a main character, along with the new 'guardian of fire' character, who could be an original creation for the fanfiction.
Another theme is power and growth. The fairy guardian usually brings some unique power or knowledge that helps Naruto in his development as a ninja. It could be a new jutsu or a way to control his chakra better.
Power and growth is also a frequent theme. Characters from both universes usually have to develop their powers further in order to face the new threats that come with the crossover. For example, a Naruto character might learn to use some Fairy Tail - style magic, or vice versa, which shows their growth.
