What are some interesting plot ideas in Dragon Ball Super Si Fanfiction?

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 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 Trunks and Mai going on a time - traveling adventure together to prevent a new threat in an alternate timeline. They could use their combined skills and knowledge to outwit the enemy.

Maybe Raditz gets sent to an alternate universe in Dragon Ball Super. There, he meets different versions of the Z - fighters. He has to team up with them to fight a common enemy that is threatening both universes. This would allow for some cool battles and character development for Raditz as he learns from these new allies.

One idea could be a time - traveling adventure. The Super Trio (let's say Goku, Vegeta and Gohan) get sent to a different era in the Dragon Ball universe, like the age of the Saiyans' home planet. They have to deal with the primitive Saiyan culture while also trying to find a way back home.

One idea could be a tournament where characters from Dragon Ball and Smash Bros universes compete for a super powerful artifact. This would bring together the unique fighting styles of both, like Goku's Kamehameha against Mario's fireballs.

One idea could be a story where the Saiyan Blue form has an unexpected side effect. For example, it could start to drain the user's life force slowly but surely. Goku discovers this during a battle and has to find a way to either control it or reverse the effect while still fighting powerful foes.

One idea could be creating a new character who has a unique power that challenges the existing power hierarchy in the Dragon Ball Super universe. For example, a character who can manipulate time in a different way than Whis or Beerus. Another plot could involve a tournament where fighters from different universes have to team up in unexpected combinations. This would lead to new rivalries and friendships. And perhaps a plot where the Dragon Balls are used in a completely different way, like to restore a destroyed universe but with some unforeseen consequences.
