One idea could be Trunks traveling to an alternate universe where the rules of DBZ are slightly different. For example, the Saiyans never lost their planet but have a different culture. Another could be Trunks teaming up with a character from a different anime in the Dragon Ball Z world to fight a new, powerful enemy. Maybe a character from Naruto who has unique jutsu skills that could combine with Trunks' power in an interesting way.
First, decide on the other universe or character you want to cross over with Trunks. Then, think about how the two will meet. For example, if it's a crossover with a character from One Piece, you could have a strange energy anomaly that sucks Trunks into the One Piece world. Next, plan out the basic plot, like what their common goal will be, whether it's to defeat a new villain or find a way back to their respective worlds.
Another theme is power - up. Trunks is always looking to become stronger to protect his world. Fan fictions often involve him finding new ways to increase his power, like fusing with other characters in unique ways or unlocking hidden potentials in different universes. For example, he might fuse with a character from another crossover universe and gain new abilities. This not only makes for an interesting story but also shows his growth as a character.
It could be his father, Vegeta. Vegeta is known for his strict training methods and high expectations. If Trunks fails to meet those, Vegeta might punish him to make him stronger.
Yes, there are quite a few out there. Some explore their relationship in unique ways, like Trunks protecting Pan during a new threat in the Dragon Ball universe. You can find them on various fanfiction websites.
Sure. 'Trunks: The Lost Warrior' is a great one. It delves deep into a scenario where Trunks gets separated from his timeline and has to find his way back. It's full of action and his character development is really well - written.
One interesting dbz trunks fanfiction could be about Trunks' time - traveling adventures in more detail. Maybe it focuses on his experiences in the past and how they shape his character in the present. For example, his interactions with the Z - fighters in the past timeline and how that knowledge helps him in his own time.
There's also 'Trunks and the Fusion Realm'. In this fan fic, Trunks somehow gets transported to a realm where fusions are the norm. He has to figure out how to survive and get back home while interacting with unique fusion characters. It's really exciting as it explores new aspects of the DBZ universe related to fusions.
A fanfic could focus on Female Trunks' relationships. Maybe she has a special friendship with Bulma that is different from the original male Trunks' relationship with his mother. She could also have romantic interests that are shaped by her being a Saiyan and her place in the DBZ universe. It could explore how she balances her Saiyan warrior side with her more emotional and relationship - oriented side.
