Maybe in the fanfiction, Naruto's henge as Inari gets involved in a village mystery. The villagers mistake him for the real Inari and ask for his help. Naruto, while in Inari's form, has to use his ninja skills and wits to solve the mystery, all the while keeping his true identity a secret.
One idea could be that Naruto uses his henge to transform into Inari to teach the real Inari a lesson about self - confidence. He could go through a day in Inari's life, facing the same challenges Inari does, but handling them in a more positive way, inspiring the real Inari to change.
One idea could be the main character, who is a henge master, getting involved in a mission where they have to use their henge skills to infiltrate an enemy stronghold. They could transform into various characters to gather intelligence.
One idea could be that Naruto uses his transformation jutsu (henge) to transform into Latias. He could then use Latias' abilities like flying and psychic powers to his advantage in a battle. Maybe he's in a new, strange land where Pokémon exist and has to blend in by using the henge.
One idea could be Naruto using the Solid Henge to create complex and long - lasting structures for strategic purposes in a battle. For example, he could make a huge fortress that the enemy has to break through, adding an interesting twist to the fight.
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.
One idea could be Naruto using his henge to transform into the Kyuubi in a different way than expected. For example, instead of just looking like the Kyuubi, he could also gain some of its powers in a limited form while in the henge. This could lead to him surprising his enemies and allies alike.
One idea could be Naruto using the Henge no Jutsu in creative ways during a mission. For example, he could transform into a famous ninja from the past to deceive the enemy. Another idea is that Naruto accidentally henges into a different form that has unexpected powers.
One idea could be that the female Kyuubi form uses her unique powers in a way Naruto has never thought of. For example, she might be able to communicate with animals in a more profound way due to her connection with nature as a nine - tailed fox. Another plot could revolve around how she has to hide her femininity while in the Henge form to avoid unwanted attention in the ninja world. Maybe she struggles with maintaining the balance between her human - like emotions and the wild nature of the Kyuubi.
One idea could be that a girl uses the henge technique to transform into different characters while at the beach in a swimsuit. For example, she could transform into Naruto to compete in a beach volleyball game in his style, leading to some comical and action - packed moments.
Well, Naruto could learn more about empathy. By being in Inari's form, he experiences life from Inari's perspective. This might make him more sensitive to the feelings of others who are not as confident or strong as he is.
Perhaps there's an enemy who is only attracted to beautiful women in swimsuits and Naruto uses the Henge to lure the enemy into a trap. He has to perfect his female mannerisms and appearance to be convincing enough to draw the enemy in. Along the way, he might get help from Ino to style his 'female' look.
