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).
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.
Chi - Chi is often a key character. As Goku's wife in the original series, she has a significant role in fanfictions too. She can be shown in different ways, sometimes being more protective or sometimes more involved in Goku's adventures with his harem - like group.
Well, in these fanfics, Bulma might be an important character. She could use her intelligence to create some sort of device or plan to stop Evil Goku. Also, Piccolo would be there. His strategic mind and powerful attacks would be crucial in the fight. And of course, there might be new characters created specifically for the fanfic, like a mysterious sage who knows the secrets to defeating Evil Goku.
Goku is almost surely a main character. His never - ending pursuit of strength and his role as the protector of Earth make him a central figure. Bulma could also be a main character in this fanfiction. She is highly intelligent and often provides crucial technological support in the Dragon Ball universe. Also, Goten might be involved as he is Goku's son and could play a part in whatever events are unfolding in this 'future' - related story.
The reaction of the Dragon Ball characters to Thanatos' invasion would be complex. Goku, as always, would approach it with a sense of adventure and the desire to test his limits. He would be the first to reach out to Thanatos in combat. Vegeta would be seething with anger at the thought of someone invading their territory. He would fight with all his might, using his Galick Gun and other powerful attacks. For the younger characters like Trunks and Goten, they would be inspired by the older fighters. They would follow their lead and contribute in their own ways. The non - Saiyan characters like Krillin and Tien would use their unique fighting styles and skills. The Dragon Ball universe has a long history of coming together against threats, and this would be no different.
Another popular character is Beerus. Since he is a powerful god in the Dragon Ball universe, when paired with Godlike Goku, it can lead to some really interesting power dynamics. They could have battles that shake the very fabric of the universe or team up to deal with an emerging evil that threatens the balance of all the realms.
Well, the Dragon Ball manga could go in various directions. It might introduce new villains, focus more on character development, or even have crossovers with other popular manga series.
The main characters are obviously Goku and Bulma. Goku is the Saiyan hero with his incredible strength and his never - ending appetite for fighting strong opponents. Bulma is the brilliant scientist who is always inventing new things to help in their adventures.
