To develop Gohan's character in the fanfic, we could see him become more confident in his feelings for Android 18. He could start off shy and reserved but as the story progresses, he becomes more open and assertive. Maybe he even stands up to his mother or other family members if they oppose the relationship. Android 18's character development could involve her becoming more vulnerable. She's always been strong and independent, but with Gohan, she can learn to let her guard down. This could be shown through her sharing her fears and insecurities with Gohan, which in turn deepens their relationship.
For Gohan, his character could be developed by showing his struggle to balance his family life with his new relationship with Android 18. He might be hesitant at first because of his responsibilities. For Android 18, her character could be developed by exploring her emotions more deeply. Since she was an android originally, she could learn about love and friendship in a new way through her relationship with Gohan.
Gohan's character can be developed by having him face challenges that test his relationship with Android 18. For example, if the other Z - fighters don't approve of their relationship at first, Gohan has to decide how much he values it. He can also grow as a character by learning from Android 18's more practical and no - nonsense approach to life. Android 18, on the other hand, can develop by becoming more empathetic. As she spends time with Gohan, she can start to understand the importance of things like family and emotional connections, which are things she may not have fully grasped before.
Their relationship could be developed realistically by having them work towards a common goal. For example, they might be trying to stop a new villain from taking over the world. As they plan and execute their strategies, they see the best and worst in each other. Gohan might see Android 18's determination even in the face of great danger, and Android 18 might see Gohan's selflessness. These experiences can bring them closer and form a relationship based on trust and admiration.
Their relationship can be developed through shared battles. When they fight side by side against a common enemy, they learn to trust each other's combat skills. For example, if they face a group of powerful villains, Gohan can rely on Android 18's precision attacks and she can count on his brute strength. This mutual trust can be the foundation for a deeper relationship.
For Future Gohan, his character could be developed by showing his struggle to maintain hope in a desolate world. He could start to open up more to Bulma about his fears and insecurities. Bulma, on the other hand, could be developed by showing her determination to not let the Androids completely destroy their way of life. She might become more tenacious and less afraid to take risks. Their relationship could be developed as they rely on each other more and more, with Gohan seeing Bulma as more than just a friend who helps him, and Bulma seeing Gohan as a symbol of hope.
For the OC, you can start by giving them a distinct backstory. If they had a tough childhood, it might make them more resilient and street - smart. This could contrast with Android 18's initially cold and detached personality. The OC could gradually break through Android 18's walls with their kindness and determination. For Android 18, her experiences with the OC could make her more open and empathetic. Maybe she starts to care more about the well - being of others, especially the OC.
Their relationship can develop through mutual respect. Gohan respects Android 21's strength and intelligence, while Android 21 respects Gohan's kind heart. This respect can turn into friendship first. For example, they train together, learning from each other's fighting styles. Then, as they spend more time together, they start to notice little things about each other that they like, which gradually leads to a romantic relationship.
One possibility could be that in the fanfic, Android 18 sees Gohan's kind heart and strength. She might start to develop feelings for him as she watches him protect the Earth. Their relationship could be an interesting mix of her android nature and his Saiyan - human hybrid nature.
For Krillin, he could be developed by showing his growth in confidence. Maybe he takes on bigger threats without hesitation. For Android 18, her softer side could be explored more, like her maternal instincts if they have a child.
To develop Android 17 further, you could explore his relationship with nature more. Since he has that love for animals, show him trying to protect a large area of wildlife from human destruction. This would not only show his growth in his beliefs but also his ability to take on big challenges.
It depends on the specific fanfic. There are a vast number of Dragon Ball fanfics out there, and while some may choose to have Android 17 be Gohan's teacher, others might not. Some fanfics focus more on the battle aspects, while others explore different character interactions. So, you really have to search through different fanfics to find ones where this is the case.
A fanfic with Android 18, Gohan and lemon could be centered around a mystery. Maybe there's a lemon - scented object that has some sort of power or significance. Android 18 and Gohan team up to figure out what it is. It could lead to them exploring new places and getting to know each other better.
