The 'lemon' in an Android 18 fanfic could imply a sense of freshness. Her character is already quite unique, being an Android. So, the fanfic could play on that by having her bring a new perspective to the story. For instance, she might introduce new technology or ways of thinking to the other characters.
Some fanfictions might portray them as protectors. They could be the ones to stand up against any form of injustice in the world of the story. Their android abilities give them an edge in these situations. They are also sometimes shown as curious about human culture. For instance, they might try different human foods or participate in human festivals, which adds a fun and relatable aspect to their portrayals.
One common storyline could be their adaptation to human society. They might struggle with understanding human emotions and relationships. For example, in some fanfictions, they could be learning about friendship in a more in - depth way. Another could be their adventures together, perhaps using their unique powers to solve problems in the world they live in.
They might start with some hesitant glances and then progress to small touches during their training sessions together. Eventually, they could share some passionate embraces.
Well, it could be a relationship based on power dynamics. Goku is extremely powerful, and Android 21 is no slouch either. They might engage in battles that gradually turn into a form of respect for each other's abilities. And then, this respect could evolve into a deeper connection. For example, Goku could teach Android 21 about the joys of a fair fight, and she could in turn show Goku some of her unique Android - related skills or knowledge.
Maybe in the fanfiction, Goku accidentally uses a new technique that causes him and Android 18 to be mentally linked. Through this link, they start to understand each other on a deeper level. They then find themselves drawn to each other's strength and determination. But they have to hide their growing relationship from their friends and family who might not understand.
The contrast between their worlds. Naruto comes from a world of ninjas, chakra, and elemental powers, while Android 21 is from a more technologically advanced setting with androids and superhuman abilities. When these two are put together in a fanfiction, it creates a unique blend of different concepts that can be really exciting to explore.
It could be a story where Naruto's positive energy starts to influence Android 21's darker side. Android 21 has a somewhat sinister side to her in the original context. But Naruto's infectious optimism and his belief in the good of people could start to change her. They might go on a journey to find a way to completely purge Android 21 of her negative tendencies, and in the process, they develop a deep bond.
Common themes often involve the unexpectedness of their relationship. Since Goku is a pure - hearted warrior and Android 18 was initially an enemy. In lemon fanfictions, there might be a focus on the passion that arises from this unusual pairing. Also, themes related to redemption and acceptance can be found, as Android 18 might find acceptance in Goku's world, and Goku might see her in a new light. This all gets intertwined with the more 'lemon' aspects which are often used to heighten the intensity of their relationship.
An Android 18 lemon fanfic could take on many forms. One idea could be that Android 18 discovers a new side of herself. She might start to have emotions she didn't expect, like a newfound sense of compassion or even a love for art or music. The 'lemon' part could be used as a metaphor for something sour that she has to overcome, like a difficult past or a misunderstanding with other characters. This could lead to a journey of self - discovery and growth for her, making for a really engaging fanfic.
