One possible plot could be a battle of ideologies. Android 18, being a former villain turned anti - hero, might have different views on protecting the world compared to Future Trunks. Maybe Android 18 is more focused on self - preservation and the well - being of her small circle, while Future Trunks is all about saving the entire world from future threats. Their clash could lead to an epic physical fight where they test each other's limits.
Android 18. She has incredible strength and durability. Her android body gives her an edge in a physical fight. She can take a lot of damage and keep on fighting. Future Trunks is strong, but Android 18's power is on a different level.
Well, there's a fanfic called 'Trunks' Time - Travel Tales' that's really good. It plays around with the concept of Trunks' time - traveling in a very creative way. Then there's 'Future Trunks' Love Story' which, as the name suggests, focuses on his romantic relationships. Also, 'The Legend of Future Trunks' is a must - read as it expands on his character and his place in the Dragon Ball universe.
One common theme is time-travel. Since Trunks is known for his time - traveling adventures, many fanfictions explore this aspect further, like dealing with the consequences of changing timelines.
She can be quite independent. In fanfic, female Future Trunks is usually shown as someone who can make her own decisions and follow through with them. She doesn't rely on others easily and is confident in her abilities. She might go on solo missions to save the day, which shows her self - reliance. Moreover, she may also possess a unique sense of style that sets her apart from other characters in the Dragon Ball universe, which adds to her charm in the fanfic world.
He becomes more resourceful. In his own time, he's used to a certain set of circumstances. But during time travel, he has to adapt quickly to new situations and find ways to use the resources available in the past. For example, he might have to figure out how to use different senzu beans or power - up techniques that are new to him.
You need to do a lot of research. Watch Dragon Ball Z to fully grasp Future Trunks' character traits and his world. And of course, be familiar with the MLP series. When writing, focus on the character development. Let the two different sets of characters grow and change as they interact with each other. Maybe Trunks becomes more in touch with his softer side through the influence of the ponies, and the ponies become more confident in facing danger because of Trunks.
One great Future Trunks love fanfiction is 'Trunks' Heart.' It delves deep into his relationship with a new character. The story is beautifully written, with detailed descriptions of their interactions and how their love develops over time. It shows a different side of Trunks, a more vulnerable and loving side that we don't always see in the original series.
