Some fanfictions may focus on the Grand Priest's relationship with the other angels. For example, a story could explore how he trains and mentors them. It could also delve into any possible rivalries or tensions among them, with the Grand Priest having to play a mediator role. This would give more depth to the whole angel hierarchy in the Dragon Ball lore.
One interesting Grand Priest fanfiction could be one where he has a secret past that is slowly revealed. Maybe he was once a regular Saiyan who was chosen by the gods for a special purpose. This could lead to a whole new perspective on his character and his actions in the Dragon Ball universe.
There is a fanfiction that explores the Grand Priest's origin. It details how he came to be in his position of power. It involves a lot of lore from different parts of the Dragon Ball universe and ties them together in a really interesting way. It's a long read but well worth it if you're interested in the character.
In the Dragon Ball Super series, the Great Divine Priest had 13 children. The angels of the twelve universes were all children of the Great Divine Priest. Their strength was far above the God of Destruction. These angels, like Weiss, had light blue complexions. This characteristic was similar to that of the high priest.
One idea could be exploring the Grand Priest's past. Maybe he had a different role in the universe long ago. Another could be a story where the Grand Priest has to make a difficult decision that goes against the will of the Omni - King. Or perhaps a story where the Grand Priest trains a new character to become a powerful being in the Dragon Ball universe.
It could be another powerful being from outside the known Dragon Ball universe. Maybe a being from a parallel dimension who sees the Grand Priest as a threat to his own plans for universal domination. Another option could be a rogue Angel who has turned against the Grand Priest and the current order of things in the multiverse.
In the finale of Dragon Ball MT, Goku had actually died in the battle with the Super One-Star Dragon. It was the Dragon God who revived him in a special form. At this time, he was no longer human. After defeating the One-Star Dragon, Wukong left with the Divine Dragon. The Dragon Pearl merged into his body and began the purification process. There were many scenes that hinted that Wukong's human body was dead. For example, the combat suit he left behind was picked up by Xiaofang, and there were no footprints when he went to visit Clint. Some people thought that Wukong had become a god and had gone to another world with the Dragon God. In the end, the old Xiaofang saw Wukong return. This ending meant that Earthlings had to solve their own problems, not rely on Dragon Ball or always let Goku solve their problems. The story of the Dragon Ball ended with Goku and the Dragon God flying away, which also announced that the Dragon Ball world was about to say goodbye, but the wonderful stories of the Dragon Ball world still remained in people's hearts.
There are fanfictions where Bulma travels to different timelines. In these stories, she might meet alternate versions of herself or the other characters. For example, she could end up in a timeline where Vegeta never came to Earth, and she has to find a way to return to her own timeline while also dealing with the differences in this new world. It makes for a really exciting read as she tries to adapt and use her wits to survive.
There could be a fanfiction where Beerus has to train a new saiyan. This would be cool as we could see his unique training methods and how he might deal with the saiyan's stubbornness. He might use his godly powers to push the saiyan to new limits. It would also show his relationship with the saiyan race from a different perspective. Beerus is known for his laid - back but powerful nature, and this would be an interesting dynamic to explore in the story.
One interesting 'Dragon Ball Trunks' fanfiction could be one where Trunks has to face an alternate version of himself from a different timeline. It could explore his inner struggle as he tries to understand how different choices could have led to such a different version of himself.
One interesting Dragon Ball Champa fanfiction could be about his backstory before coming to the Tournament of Power. It might explore his relationship with Beerus in more depth and how they became rivals.
One interesting Gin Dragon Ball fanfiction could be about Gin, a new character, joining Goku and the gang on their adventures. Maybe Gin has a unique power that helps them in battles against new villains. Another could be a fanfiction where Gin is from a different dimension and has to adjust to the Dragon Ball universe's rules.
