Definitely their strong bond. They have been through so much together, so highlighting their loyalty and trust for each other is great. Also, their different fighting styles can add action - packed scenes. For example, Gohan's more methodical and strategic approach against Trunks' more impulsive and aggressive style.
Perhaps a plot where Future Gohan and Future Trunks accidentally travel to an alternate timeline. There, they have to team up with different versions of themselves to defeat a common enemy. This would involve exploring how they interact with these alternate selves and how they adapt to the new environment and challenges.
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.
One plot idea could be that Gohan and Trunks team up for a martial arts tournament. They train together, sharing their unique skills and techniques. During the training, they face various challenges that test their friendship and determination.
For Gohan, you could start by showing his growth from his previous experiences. Maybe he's more confident now and is taking on a leadership role. He could be mentoring Trunks in certain aspects. For Trunks, show his eagerness to learn from Gohan and his own journey of becoming stronger. He might start out a bit impulsive and learn to be more calculated as he spends time with Gohan.
One common theme is growth. Both characters often grow as individuals and in their relationship. For example, they might learn to overcome their personal fears or weaknesses while falling in love. Another theme is adventure. They usually embark on some sort of journey or face challenges together, which brings them closer.
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.
