Claudia is not a character from the original Dragon Ball series. Goku is the main protagonist of Dragon Ball. He is a Saiyan sent to Earth as a baby. He is known for his powerful fighting abilities, his love for martial arts, and his kind heart. He has saved the Earth multiple times from various threats.
Another great plot could involve Goku facing off against other Gods of Destruction who don't believe he's worthy of the title. This would lead to epic battles where he has to prove himself not just with his power but also his newfound sense of divine responsibility.
Vegeta would probably be both jealous and intrigued. Jealous because Goku has achieved a new level of power through this fusion, and intrigued because he wants to see how this new being fares against enemies. He might also be secretly glad that Frieza, his long - time enemy, is now in a form that he can tolerate (barely).
Goku's reaction could be a mix of shock and joy. On one hand, he has been on Earth for so long without any real family connection to his Saiyan side. When he sees his parents, it would be overwhelming. He would likely be in awe of his father, Bardock, given his father's reputation as a strong Saiyan. And he would be eager to bond with his mother, who he has never known. He might also feel a sense of belonging that he has been missing all his life.
There's a fanfic called 'Goku's Hidden Power'. In this story, Goku discovers a new level of power within himself that even the Kais didn't know about. It delves deep into Goku's character, exploring how he copes with this newfound strength and the responsibility that comes with it. The action scenes are also very well - written.
In a fanfiction, Goku might be weakened due to a curse. He loses his Super Saiyan powers and has to start from scratch. This could lead to a great character - development arc. He might discover new ways to fight without relying on brute strength, like using his wits and strategic thinking more, and also learning new martial arts techniques from his human friends.
Perhaps a fanfiction where Vados senses a new threat approaching the universe. She enlists Goku to help her find a way to stop it. Along the way, they encounter strange new races and powers. Goku's simple but powerful approach to fighting combined with Vados' wisdom would make for an interesting dynamic as they search for a solution to this impending doom.
Goku's understanding of different universes and races could be deepened in fanfiction. Since Dragon Ball Super introduced the multiverse concept, fanfiction could explore how Goku interacts with and learns from beings from other universes, making him more worldly and less naive in some ways.
According to my current knowledge, there is no official sequels or extras for the God and God of the Dragon Ball. Although some people claimed to have seen a work similar to the sequels, the officials did not give any relevant information or confirmation. If you want to know more about the Dragon Ball God and God, it is recommended to read related novels or comics, or consult the author or bookstore.
