Naruto himself would be a great choice. He's always been about transformation in a way, with his Nine - Tails power and his ability to change people's minds. Using the permanent henge, he could do all sorts of crazy things like infiltrating Orochimaru's lair in a new form.
Kakashi could be an interesting main character. He's full of secrets already. Using the permanent henge, he could disguise himself as one of his old comrades who has passed away to relive some memories or to teach his students a valuable lesson about the past and the sacrifices made.
One key element is the exploration of the permanent henge itself. How it was obtained, what are its limitations and powers. For example, it could be a result of a forbidden jutsu or a unique encounter. Another element is the reaction of other characters in the Naruto world. Do they see the character as a threat or an opportunity? And of course, the impact on the overall plot of the Naruto - inspired story.
One idea could be a character using the permanent henge to blend into an enemy village and discover their secrets. For example, Naruto could use it to look like a random civilian in the Sand Village and find out about their new defense strategies.
Sakura could be a great choice. She's already a strong and determined character. If she were to use the female henge to transform into the Kyuubi, it would show a new side of her power and her ability to adapt. She could use the Kyuubi's strength to protect her friends and the village in a more unexpected way compared to her usual medical and combat skills.
Sasuke could be a rival. He's always been highly skilled and competitive. His Sharingan could potentially see through some of the henge master's henges, creating a constant challenge for the henge master to come up with more advanced henges.
It could be that new characters are introduced in 'Naruto Henge Wears Fanfiction'. They might be characters who have a special connection to henges, either they are experts at using them in new ways or they are affected by the misuse of henges. These new characters could drive the plot forward along with the well - known Naruto characters.
Obviously Naruto would be one of the main characters as it's about him being the master of henge. There might also be his friends like Sasuke and Sakura. They could play roles in Naruto's journey to master henge, either by supporting him or challenging him in some way.
Sure. 'The Hidden Henge' is a great one. It explores unique storylines with the permanent henge concept in the Naruto universe. The characters are well - developed and it has some really interesting twists on the original Naruto plot.
Armin could also be a main character in such a fanfic. He's known for his intelligence. As a permanent titan, he could use his smarts in unique ways. He might try to figure out the secrets of the titan form from the inside and communicate with the other characters in unexpected ways. For example, he could leave clues or messages for his friends using his titan abilities.
He might also get help from his friends. For instance, Sasuke could sense that something is wrong with Naruto. With his Sharingan, Sasuke might be able to see through the henge and then use his own powers to help Naruto break free. Or Sakura could use her medical ninjutsu knowledge to somehow counter the effects of the henge on Naruto.
The plot could involve Naruto using the henge to transform into a swimsuit - clad figure as part of a bet. His friends bet him that he can't stay in a particular henge for a whole day, and the swimsuit henge is what he chooses. Along the way, he has to deal with the embarrassment of being in such a form in public places in the Hidden Leaf Village, like the market or the training grounds.
