Another plot could revolve around the teamwork aspect. In the Tournament of Power, we could see a group of fighters from different universes who have to work together despite their differences. They develop a new fighting style that combines their individual strengths, and their journey of learning to trust and cooperate with each other could be the main focus of the fanfiction.
Perhaps a story where a previously unknown fighter enters the Tournament of Power. This fighter has been training in seclusion and has powers that are a combination of different techniques from various universes. They start off as an underdog but quickly become a force to be reckoned with, making allies and enemies along the way.
One interesting plot twist could be a character who was thought to be weak suddenly unlocking a new and extremely powerful form during the Tournament of Power. This form gives them an edge over stronger opponents and changes the whole dynamic of the battles.
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 plot could revolve around a team-up that no one expected. Like a villain and a hero from different universes having to work together in the Tournament of Power. They start off distrusting each other but gradually learn to respect and rely on one another. This could add a whole new layer of drama and character development to the fanfiction.
If Broly joined the Tournament of Power, it would be an absolute game - changer. His raw power is off the charts. He could easily take on multiple opponents at once. He might start by targeting the strongest foes, like Jiren. His uncontrollable rage could work in his favor, as opponents would be intimidated. However, his lack of teamwork skills could also be a drawback. But with his power, he could probably just brute - force his way through many battles.
Goku is typically considered very powerful in this context. His ability to constantly evolve and reach new forms like Ultra Instinct makes him a force to be reckoned with. Vegeta is also powerful, with his own growth and development throughout the series. Then there's Jiren. His raw power and the fact that he was able to hold his own against Goku in Ultra Instinct form shows how strong he is. But it's also important to note that in fanfiction, the power levels can be adjusted and new characters can be introduced. There could be a character who is a hybrid of different races in the Dragon Ball universe and has powers that combine the best of those races, making them one of the most powerful in the tournament of power.
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.
A plot could involve Cooler getting trapped in an alternate dimension where the rules of power are different. He has to figure out how to adapt and escape while also facing off against strange new foes. Or perhaps he discovers a long - lost relative who has a connection to Earth, and this forces him to reevaluate his stance on the planet and its inhabitants.
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.
One idea could be introducing a new, underdog character who has a unique power that no one expects. For example, a character with the ability to copy and enhance the powers of those they touch. This would create an interesting dynamic in the tournament as they could turn the tables on stronger opponents.
