In a fanfiction, Future Gohan and Android 18 could have a relationship based on redemption. Android 18 has done some not - so - great things in the past. Gohan, being the good - hearted Saiyan he is, could see the potential for good in her. He might try to guide her towards a more positive path. This could involve Gohan protecting 18 from other threats, and in return, 18 could use her android powers to help Gohan in his battles. Their relationship could be a slow - burn type, gradually evolving from distrust to a strong friendship or even more, depending on how the fanfiction unfolds.
They could have adventures where they explore new planets. Gohan's curiosity as a Saiyan and 18's fearless nature would make them great explorers. Maybe they'd discover a new form of energy on an uncharted planet that could help Gohan become even stronger or give 18 some new abilities.
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.
A possible plot is that Android 21, who has some glitches in her system related to her emotions, is healed by Gohan's kindness. As a result, she starts to develop feelings for him. They then have to deal with the fact that their relationship is not accepted by some in the Z - Fighter community because of Android 21's origin. This leads to a story full of drama and self - discovery for both of them.
Definitely their strong bond. They have been through so much together, so highlighting their loyalty and trust for each other is great. Also, their different fighting styles can add action - packed scenes. For example, Gohan's more methodical and strategic approach against Trunks' more impulsive and aggressive style.
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.
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.
Maybe in the fanfiction, Android 18 gets injured while protecting Gohan from a new powerful enemy. Gohan then takes care of her and in that time of vulnerability, they realize their feelings for each other. This could lead to them exploring a relationship while also trying to figure out how to defeat the enemy that still lurks.
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.
Well, a common plot might be that Gohan discovers a new side of Android 18. Maybe she has a hidden talent for cooking or art, and Gohan is really intrigued by this. They could start spending more time together exploring her newfound interests. Or perhaps there's a plot where an old enemy returns, and Gohan and Android 18 are the only ones who can stop it. In the process, they realize their feelings for each other are stronger than they thought. Another one could be a story where Android 18 is having trouble adjusting to life among the Z - fighters, and Gohan helps her fit in, which leads to a romantic relationship.
