One idea could be a fanfic where Goku discovers a new form that is a combination of Ultra Instinct and Super Saiyan God. This form gives him unique abilities and a new look. Another idea is to have Vegeta go on a solo adventure to a new planet filled with powerful foes that force him to develop a new fighting style. Maybe also a story where the Z - fighters have to team up with their old enemies like Frieza to fight a greater threat from another dimension.
A great 'dragon ball super fanfic' could be centered around the Saiyan race's history. Maybe there are some hidden Saiyan colonies that were not destroyed, and they have a different culture and way of fighting. Goku and Vegeta could discover these colonies and learn new techniques from them. Additionally, a story where Bulma creates a device that can enhance the power of the Saiyans even further, but it has some unforeseen side - effects, would be a great plot for a fanfic.
Well, a cool 'dragon ball super fanfic' plot could involve time - travel. For instance, Trunks goes back in time not just to change one event but multiple events that ended up creating an even more dangerous future. Or perhaps a story where the Dragon Balls themselves become sentient and start to manipulate the wishes made on them, causing chaos among the characters. Also, a fanfic where Piccolo trains a new generation of Namekians to be as powerful as the Z - fighters could be really interesting.
One idea could be a new villain from an unknown dimension arriving in the Dragon Ball universe. This villain has a unique power that nullifies ki attacks, forcing the Z fighters to rely on their martial arts skills alone.
One idea could be a story where Goku and Vegeta from Dragon Ball Super end up in the world of Dragon Ball GT by some sort of time - space rift. They then have to team up with the GT versions of themselves to fight a new, powerful enemy that is threatening both timelines.
A great idea for a Dragon Ball Super GT fanfic would be to explore what would happen if Vegeta was the one to find the Super Dragon Balls instead of Goku. Vegeta could have his own set of wishes that would completely change the power dynamics in the Dragon Ball universe. You could also create a story where the Z - fighters have to face a new enemy that was created as a result of the misuse of the Dragon Balls in the past, and they have to find a way to defeat it without using the Dragon Balls themselves.
One idea could be a story where a new character from an alternate timeline enters the Xenoverse 2 world. They have a unique power that disrupts the normal flow of time rifts. This new character teams up with the Time Patrollers to fix the chaos they unknowingly caused. Another could be a fanfic focusing on the backstory of an existing minor character in the game, like how they came to be a part of the Xenoverse in the first place.
One idea could be a time - traveling adventure where the heroes from different eras of Dragon Ball come together to face a new, powerful enemy in the Heroes universe. For example, Goku from the Saiyan Saga teams up with Goku Ultra Instinct from a later time.
A third idea is to focus on a tournament among the new generation. But instead of just physical combat, it also includes challenges related to knowledge of the Dragon Balls' history and power. This would not only test their fighting abilities but also their understanding of their own heritage.
One idea could be exploring an alternate timeline where Goku never hit his head as a child. He might grow up as a ruthless Saiyan warrior, changing the entire dynamic of the Dragon Ball universe.
Another plot could involve Towa traveling to different timelines not just to cause chaos, but to find a way to bring back a lost loved one. Maybe she has a family member from her own race who was killed in a long - ago battle, and she believes that by manipulating the Dragon Ball timelines, she can resurrect them. Along the way, she has to deal with the Z - Fighters who are trying to stop her time - meddling.
One interesting plot idea could be the return of an ancient and powerful villain from the Dragon Ball universe that was thought to be long forgotten. This villain could have powers that even the Gods of Destruction are wary of, forcing Goku and his friends to train in new and extreme ways.
A plot could revolve around a group of underdog fighters in Universe 2 who train in secret to enter the Tournament of Power. They face numerous challenges during their training, including a lack of resources and interference from more powerful groups. But through their determination and unique fighting styles, they manage to make a name for themselves in the tournament.
