In fanfiction, if Goku trains with Grand Priest, he might achieve new levels of power. Goku is always eager to get stronger, and the Grand Priest is extremely powerful. He could learn new techniques that are beyond the Saiyan's current understanding, perhaps even something related to the Angels' unique powers.
Goku could develop a deeper understanding of the power he wields. The Grand Priest's training would not only focus on physical strength but also on the spiritual aspect of ki. This could lead to Goku having a more profound connection with his Saiyan heritage and the energy that flows within him. He may also become more patient, as the Grand Priest's training methods might be complex and require time to master.
There were a few novels that could be recommended. One of them was " Nirvana Rebirth: The AdorkablePrincess Wants Candies." The protagonist wanted to eat candy the first time they met, and the plot was very sweet. The other book was " You're Not as Bright as I Am ". The first time the male and female leads met was during an internship. The female lead grabbed the male lead's wrist and refused to let go. The male lead refused the female lead's invitation, but in the end, he sent the female lead home. The other book was " The Conquest Game: A Beautiful Wife Is Hard to Tame." The male and female protagonists met for the first time in a bar, and the male protagonist mistakenly thought that the female protagonist was a lady. The second time they met was on the racing track. These novels all have different plots and backgrounds. I hope you can choose a novel that you like according to your preferences.
Another possible main character could be the villain that forces the two Gokus to meet. This villain could be a new, super - powerful threat that the two Gokus need to deal with. Their meeting becomes a crucial part of the story to defeat this powerful foe.
One idea could be a story where the Grand Priest and Zeno are on a journey through the universes to understand the different cultures. They could encounter various powerful beings and have to make decisions about how to handle them. For example, they might come across a universe where the inhabitants are facing a great danger and they decide to use their powers to help.
I haven't actually read this fanfic yet. But if it's about Zeno and the Grand Priest, it could be really interesting. Maybe it explores their relationship in a whole new way, like how they interact behind the scenes in the multiverse. It could also introduce some unique plot twists based on their powerful positions in the Dragon Ball universe.
Fanfiction about the Grand Priest and a reader can be really interesting. It often explores unique relationships. Some might focus on the Grand Priest's mysterious nature and how the reader character interacts with it. It could be a story of adventure where the reader gets involved in the Grand Priest's world.
Well, it could be about Goku Jr learning some of Goku's most powerful moves. Maybe Goku teaches him the Kamehameha. They might also go on an adventure together, like fighting a new and powerful enemy that neither could face alone.
