Maybe Elsa's powers get out of control and Naruto, with his skills, comes to her world to help. During the process, they start to fall for each other. And in the context of lemon fanfiction, it could lead to some steamy scenes that involve their emotions and physical closeness, which is not really suitable for a general audience.
A plot could be that there is a magical mix - up that brings Naruto and Elsa together. They have to work together to solve the problem. As they spend time together, they discover new things about each other and feelings start to develop. But when it comes to lemon fanfiction, it often adds in sexual or overly romantic and sensual elements that deviate from the more innocent crossovers. It's important to note that this type of fanfiction is often not for everyone and may not adhere to the original characters' personalities in a proper way.
One possible plot could be that Naruto somehow ends up in Elsa's world and they initially have a misunderstanding but then gradually develop an attraction. And then, in a rather inappropriate way for non - lemon versions, there could be some romantic and more adult - themed interactions.
Perhaps Tora accidentally eats a lemon - shaped fruit that gives it the ability to talk. Naruto then has to keep Tora's new ability a secret while they go on a journey together to find a way to reverse it. Along the way, they face many challenges and meet different characters from the Naruto universe.
One possible plot could be that female Naruto discovers a hidden grove of lemon trees that have special powers. Akamaru senses danger around the grove and together they have to protect it from enemy ninjas. Another plot could be that a lemon - themed mission is given to female Naruto and Akamaru, like they have to retrieve a rare lemon for the village's medicine.
One possible plot could be that Naruto somehow gets transported to the Land of Ooo (where Princess Bubblegum is from). He could team up with her to fight a common enemy, like a powerful new villain that threatens both their worlds. Naruto's ninja skills and Princess Bubblegum's scientific knowledge and leadership could be combined to defeat the foe.
I'm not really into that kind of crossover lemon fanfiction, but you can try searching on some fanfiction websites like Archive of Our Own. Just be aware that not all such content may be appropriate or well - written.
One major problem is that it's a non - canon and rather strange combination. Naruto is from a ninja - themed anime and Elsa is from a Disney princess movie. Mixing them in a 'lemon' context is disrespectful to the original concepts of both.
A plot could be that a lemon - loving Pokémon starts causing trouble in the area where Ash and Squirtle are. Ash and Squirtle team up to stop it, and along the way, they discover that the lemon - loving Pokémon has a sad backstory related to being over - hunted for its love of lemons. They then try to find a way to protect it and also satisfy its lemon cravings in a more sustainable way.
One plot could involve a lemon - themed Pokémon contest. Misty wants to enter and win, but she needs a special Pokémon with unique abilities. Mewtwo, who has been observing humans from afar, decides to help her. They train together, and during the process, they face many challenges. The lemon aspect could be incorporated in the design of the contest stage or the types of Pokémon moves that are more effective during the contest. In the end, they not only become closer friends but also gain a new understanding of each other's worlds.
A plot might involve a girl who has a special ability to communicate with insects. She meets a particular insect that is different from the others. As they interact more, there could be a slow - burning relationship. In the context of 'lemon', it could mean that there are some more adult - like emotions and interactions, like a kind of forbidden love or a very intense connection that defies the norms of human - insect relationships.
In a 'Naruto is Ranma' fanfiction, a possible plot could involve a powerful villain who wants to use the powers of both Naruto's ninja world and Ranma's world for evil. Naruto and Ranma would then have to team up, along with their respective friends. Naruto could teach Ranma's friends some basic ninja skills, and Ranma could show Naruto's friends how to handle his transformation curse. This would lead to a lot of comical and action - packed situations as they fight the villain and try to save both worlds.
One plot could be that Naruto is discovered by a traveling minstrel who sees his potential and decides to train him. As he becomes a singer, he uses his new - found fame to promote peace between the villages, using his songs to tell the stories of the ninja world and the importance of unity.
