Yamcha could be a good addition. He has his own martial arts skills and a history with Goku. His insecurities about being overshadowed by Goku can be explored in a male - centric fanfiction. Tien is another strong character. His multi - armed fighting style and his disciplined approach to martial arts can make for some exciting scenes when paired with Goku. And let's not forget Gohan. As Goku's son, he has his own story arc and powers that can be incorporated into the fanfiction in an interesting way.
Vegeta would be a great addition. His rivalry with Goku and his pride as a Saiyan would add an interesting dynamic. He might be initially jealous that Goku is getting to fight and train with the God of Destruction. But then he would also want to prove himself and join in the action. Whis could also be included. His knowledge and calm demeanor could help in situations where the power of Goku and the God of Destruction gets out of hand.
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.
Vegeta from the Dragon Ball series is often popular. Fans like to write about his reaction to Naruto's world and how he might interact with the characters there. Also, Sasuke from Naruto is frequently included. He could be a rival or an ally in the fanfiction, given his complex character. Another one could be Piccolo. His calm and strategic mind would be interesting to incorporate in stories involving Naruto's more chaotic ninja world.
Bulma could be involved. Since she has a relationship with Vegeta and is friends with Goku, she might try to mediate between them when Goku snaps at Vegeta. She could be the voice of reason, trying to calm both of them down and make them see each other's point of view.
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.
Bulma could be one of the main characters. She has been with Goku since the beginning and could play a role in bringing the reader and Goku together. Maybe she discovers some old technology that has a connection to the reader and uses it to reunite them.
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.
Vegeta is a great choice. His rivalry with Goku adds a lot of drama and action to a fanfic. Also, Piccolo, as he has a long history with Goku and has been both an enemy and a friend. Another good character could be Gohan, Goku's son, as it can explore their father - son relationship further in the fanfic.
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.
In some 'Goku meets Goku fanfiction', they could team up against a super powerful enemy that neither could defeat alone. They would combine their signature moves like the Kamehameha for an ultimate attack.
