In some fanfictions, there could be a rogue Android. This Android might have been created by a mad scientist and has its own agenda. It could be super - strong and intelligent, constantly devising plans to either destroy Trunks and Pan or use them to achieve its own goals. Maybe it wants to use the Dragon Balls to upgrade itself further and become invincible.
One interesting storyline could be Trunks and Pan going on a quest to find a rare Dragon Ball that has been lost in a parallel dimension. They face all kinds of strange creatures and challenges along the way.
Their relationship could develop through training together. As they train, they learn to respect each other's abilities more. For example, Trunks might be impressed by Pan's tenacity and Pan could admire Trunks' strength.
One interesting plot could be that Pan and Trunks go on a journey to find a lost Dragon Ball. Along the way, they encounter new enemies and have to use their combined skills to defeat them. They might also discover a new form of energy that is related to the Dragon Balls.
A fanfiction could explore Pan's journey as a Super Saiyan in Dragon Ball GT in relation to her family heritage. She might struggle with the pressure of living up to the Saiyan legacy. Her Super Saiyan transformation could be a turning point where she finally accepts her role and uses her power to protect those she loves, while also learning about the true meaning of being a Saiyan.
Well, clearly Trunks and Pan are the main characters. Trunks is a half - Saiyan with a strong sense of justice and great power. Pan is also a Saiyan - human hybrid, full of energy and determination. Their different personalities and abilities make them interesting to write about in fanfiction.
A possible fanfiction could be set in a future where Pan discovers a hidden power within herself. Trunks, being the more experienced one, helps her control and master it. They could face off against a new, mysterious enemy together, and through their battles and shared experiences, their relationship deepens as they rely on each other's strengths.
One interesting storyline could be Trunks and Pan going on a time - traveling adventure together. They might visit different eras in the Dragon Ball universe and face various challenges that were not part of the original story. For example, they could end up in a time when the Saiyans were still on Planet Vegeta and have to figure out how to get back home without disrupting the timeline too much.
One common theme is growth. They both grow as characters, whether it's in terms of their fighting abilities or their emotional maturity. For example, in many fanfictions, Trunks helps Pan to become a better fighter and Pan helps Trunks to open up more emotionally.
One interesting fanfiction could be where Baby Pan discovers a hidden power within herself to resist Baby's control in a more unique way than in the original story. Maybe she forms an unexpected alliance with some of the other Z - fighters.
