Black Hanewana's personality could start off as mysterious. As the fanfiction progresses, the lemon aspect could be used to show a more gentle side. Maybe the lemon - scented aura represents a form of inner peace for Black Hanewana. Naruto's presence could gradually draw out this side, as they interact more and more. For instance, when Naruto gets into trouble, Black Hanewana uses its lemon - related powers in a protective way, revealing its caring nature.
For Naruto, his usual determination and cheerfulness can be maintained but with a new layer of vulnerability when it comes to his relationship with Madara. He might be more hesitant and shy in expressing his feelings at first. Madara, on the other hand, could have his stoic and powerful facade start to crack as he falls for Naruto. His cold exterior could give way to a more protective and affectionate side.
Naruto's personality could develop by him becoming more confident in his abilities due to the Kyuubi. He might start to see himself as not just a jinchuriki, but as a force to be reckoned with. Itachi's personality could be developed by showing his softer side when interacting with Naruto and the Kyuubi. For instance, he could show more empathy towards Naruto's struggle with the Kyuubi's power, and this could change how others in the fanfiction view him.
For Optimus, his sense of duty and leadership can be further explored. In a fanfiction, we can show how he balances his leadership role with his personal relationships, like with Bumblebee. For example, he might struggle between making the tough decisions for the group and protecting Bumblebee from harm.
Naruto's loyalty and his belief in friendship can be deepened in the fanfic. When he meets Rukia, he could start to understand different types of loyalty, like Rukia's loyalty to Soul Society. Meanwhile, Rukia's sense of justice might be challenged and broadened by Naruto's more free - spirited approach to right and wrong. This interaction would lead to the development of both characters in new and interesting ways. Naruto might also start to show a more mature side as he realizes the weight of Rukia's responsibilities, and Rukia could become more in touch with her own emotions as she experiences Naruto's passion.
For Naruto, his usual determination and eagerness to protect his friends can be maintained, but with an added layer of confusion when it comes to his feelings for Orochimaru. He might struggle with the idea of being attracted to someone who was once an enemy. Orochimaru, on the other hand, his cold and calculating nature could start to thaw. His curiosity about Naruto could turn into a more affectionate side, but he would still retain some of his mystery and ambition.
For Naruto, you could develop his character by showing how he reacts to Anko's more unpredictable nature. Since he is used to more straightforward people like his friends in Konoha, Anko's quirks could make him grow in terms of patience and adaptability.
For Juvia, you could explore her more vulnerable side. In lemon fanfiction, she could be shown as being more hesitant about her relationship with Gray at times, not just her usual over - the - top loving self. This would add depth to her character.
For Pikachu, you could develop his curious side more. Maybe he's always eager to explore new areas in the fanfiction, which sometimes gets him into trouble. Sylveon could be shown as the more cautious one, using its ribbons to hold Pikachu back when he's about to rush into danger.
Lucy's personality can be developed by putting her in different scenarios at Happy Lemon. Say she's a bit of a perfectionist. At Happy Lemon, she might notice that the presentation of the drinks isn't always perfect. Instead of just complaining, she could start helping the staff to improve it, which would make her more understanding and less critical. As for the Happy Lemon characters, like the employees, if they start off as a bit lazy, they could be inspired by Lucy's enthusiasm to become more hard - working and take pride in their work. You can also have Lucy introduce new ideas to the Happy Lemon crew, which would make them more open - minded over time.
Maybe in the fanfiction, Black Hanewana has a lemon - scented aura that Naruto initially finds strange but later realizes it can be used to calm angry villagers. They then go on a journey to find the source of this aura and its connection to an ancient prophecy.
