Definitely include Whis. His knowledge and his ability to train Goku can be a great plot point. Beerus, the God of Destruction, can also be included. His temper and his power can create high - stakes situations in the fanfiction. Additionally, Chi - Chi could be added. Her possessive love for Goku can create conflict when it comes to Bulma's friendship with Goku. And Future Trunks is another character that can bring a sense of mystery and urgency to the story with his knowledge of future events.
I think the message from Goku manga could be anything from a call for help to a declaration of victory. Maybe it's a secret he's sharing or a strategy for a big fight. You never know with Goku!
Shinra stands no chance against Goku. Goku has gone through countless battles and has mastered powerful techniques. His strength and experience give him a huge advantage.
One pairing that pops up is Goku and Chi - Chi. Their relationship as husband and wife can be explored further in fanfiction, especially in scenarios where Goku's Saiyan nature clashes with his family responsibilities. Additionally, Trunks and Future Mai is a pairing that has some popularity. Their relationship in the future timeline and how they support each other can be the focus of some great stories.
Goku could teach Naruto how to fight without relying too much on ninjutsu. Goku mainly uses his physical strength, speed, and ki in combat. Naruto could learn to better use his own physical abilities, like hand - to - hand combat and quick dodges, which would make him a more well - rounded fighter.
Well, Vegeta would be a likely character. He might be initially suspicious of the female Goku. Maybe he thinks she's a threat or just can't believe there's another Goku - like being. He could be there to add some comical moments as he tries to understand the situation.
In general, it's a bit of a toss-up. The strength of Manga Goku and Anime Goku can vary depending on the specific arcs and battles. Sometimes, it might seem like one is stronger in a particular situation, but that could change in another.
