For making their relationship believable, you should show the development gradually. For example, if it's a friendship, start with small interactions like sharing a meal or a common interest. If it's a romantic relationship, let them first get to know each other's personalities. The OC should respect Android 21's nature, whether it's her fighting side or her more gentle, food - loving side. Also, have them face challenges together that strengthen their bond.
There is a fanfic called 'Beyond the Battlefield'. In this story, Goku and Android 18 are forced to team up for a mission. As they work together, they start to understand each other better. The author does a great job of writing their dialogues, which are full of humor and some underlying tension.
Character development is key. In a good 'Goku x Android 18 fanfic', we should see both characters grow and change because of their relationship. For example, Goku might become more in - tune with his emotions, and Android 18 could become more open. Also, an interesting plot that goes beyond the typical fight - and - save - the - world scenario is great. Maybe something like them exploring a new world together or having to solve a mystery.
One possible plot could be a story of Goku and Android 21 teaming up against a new and powerful enemy. They start off as reluctant allies. Goku is initially wary of Android 21 due to her being an android, but as they face challenges together, they begin to understand and respect each other's powers. They could learn new techniques from one another and in the end, become friends. This would be a great way to show their growth and the power of friendship across different species in the Dragon Ball universe.
The plot could be about a power struggle. Cell, always seeking more power, might see Android 18 as a key to achieving ultimate strength. Android 18, on the other hand, would resist his attempts. This back - and - forth struggle could form the core of the fanfic.
One possible theme is friendship. Despite their different origins - Future Trunks being a Saiyan from the future and Android 18 being an android created by Dr. Gero - they could develop a deep friendship. This friendship might be based on mutual respect for each other's strength and abilities.
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.
A possible relationship could be a friendly rivalry. They are both powerful in their own ways. Goku is a Saiyan with incredible physical strength and combat abilities, while Android 21 has her own set of unique powers. They might constantly challenge each other to friendly spars, which would help them both improve their skills and also deepen their understanding of each other.
Android 21 is an interesting character in the Dragon Ball series. Fanfics about her can range from exploring her backstory in more detail. For example, some fanfics might focus on her time before she became the Android we know, her relationship with other characters like Goku or Vegeta, and how she copes with her new - found powers and existence.
