One popular Android's Trunks fanfic could be 'Trunks' New Adventure'. It might explore Trunks in a new and exciting situation, like facing an unexpected threat in a different timeline. Another could be 'Trunks and the Android Alliance', which could focus on his relationships with the androids in a more in - depth way.
Well, there's a fanfic named 'Trunks: The Android Slayer'. In this, Trunks might be depicted as a powerful hero who has to overcome the challenges posed by the androids in a really intense way. There are also fanfics that might explore his personal growth, like 'Trunks' Evolution' where he develops new skills and a deeper understanding of his powers while dealing with the android situation.
Some Trunks fanfics are centered around his growth as a warrior. They might depict him training in new and unique ways, perhaps with a mentor other than the usual characters in the Dragon Ball series. This can add an interesting twist to his character development.
One popular type might be adventure - themed fanfics where Android 18 goes on quests. Another could be friendship - based ones where she forms strong bonds with other characters from the Dragon Ball universe.
One great storyline could be them teaming up against a new, powerful enemy that neither can defeat alone. They start off not trusting each other fully as they have different fighting styles. Android 17 is more of a lone wolf type, while Trunks is used to fighting alongside his friends. But as they battle, they learn to work together, with Android 17 teaching Trunks some of his unorthodox combat moves, and Trunks showing 17 the value of friendship and teamwork in a fight.
A frequent theme is also friendship. Given their different backgrounds - Android 17 being an android and Trunks being a half - Saiyan - exploring how they become friends and trust each other can be really interesting. Some fanfics also touch on the theme of sacrifice, where one of them might be put in a situation where they have to sacrifice themselves for the other or for the greater good in the Dragon Ball universe.
In some fanfictions, there's a plot where Trunks and Android 18 are sent to a different dimension. There, they have to rely on each other completely to survive and find a way back home. This forces them to put aside their differences and work as a team, which in turn creates a deep emotional connection.
There's a fanfiction titled 'Unlikely Love'. In this story, Mirai Trunks and Android 18 are brought together by a strange time - travel anomaly. The story focuses on how they overcome their initial distrust. Android 18 is initially wary of Trunks due to his Saiyan heritage, but as they spend more time together, they realize they have more in common than they thought. It's a heartwarming tale of two very different characters finding love.
Perhaps it's a story of love and redemption. Future Trunks, with his tragic past, might find solace and a new purpose in life through his relationship with Android 18. She, on the other hand, could be softened by his kindness and start to see the world in a different light.
Many Android 21 fanfics focus on her struggle with her identity. Given her complex nature, writers often delve into how she reconciles her different aspects, whether it's her more benevolent side or her more menacing side. Also, crossovers with other anime or game universes are quite popular. For example, how she would fare in a world with Naruto characters or characters from other fighting games.
Well, one great way to find Android 17 and Trunks fanfics is to check out dedicated Dragon Ball fanfic communities on platforms like Reddit. There, fans often share and recommend their favorite stories. Maybe you'll find a fanfic where Android 17 and Trunks have to face a new, unexpected threat together and how they grow as characters through that experience.
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.
