Another good option could be Whis. Whis is very knowledgeable and powerful. Pairing him with Caway would allow for some really cool storylines. He could train Caway in the ways of the angels, and Caway could bring a fresh and different energy to Whis's rather calm and collected world.
One interesting story could be about Caway's hidden powers. Maybe she discovers she has a unique ability that can change the course of a big battle in the Dragon Ball Super universe.
Gohan would be a great character to pair with Future Trunks. They are both strong and have a deep connection to protecting the future. Their combined power and intelligence could make for some really exciting storylines.
Goku is a great character to pair with Bardock. Since Goku is his son, it can create some really emotional and action - packed scenes. They can train together or fight side by side against common enemies. Another good option is Vegeta. Their different personalities as Saiyans can lead to interesting interactions. Bardock's old - school Saiyan ways compared to Vegeta's pride can make for some engaging storylines.
Another good pairing could be with Bulma. Since she is his mother in his own timeline, but in fanfiction, they could have a different kind of relationship. Maybe she helps him with some advanced technology to enhance his fighting abilities.
Vegeta could also work well. Vegeta's pride and determination, along with his powerful fighting skills, would contrast nicely with the Supreme Kai's more reserved and wise nature. They could learn from each other and have some intense rivalries within the story.
Gohan and Rock Lee would be a unique pairing. Gohan is a powerful fighter who also has an intellectual side, while Rock Lee is all about hard work and physical training. They could learn a lot from each other, like Gohan teaching Lee about energy control and Lee showing Gohan the value of intense physical conditioning.
Well, obviously Goku, Vegeta, and Gohan are the core Super Trio. But you could also include Piccolo. He has a long history with Gohan and his strategic mind could add a lot to the team. Another great addition could be Trunks. His future - knowledge and sword - fighting skills can bring a new dynamic.
Goku is, without a doubt, one of the most popular. His constant pursuit of strength and his ability to overcome seemingly impossible odds make him a favorite for fanfiction writers. They can create all kinds of new adventures for him, like facing off against cosmic threats even greater than what he's encountered in the shows.
Vegeta is also highly popular. Writers often like to write about his pride as a Saiyan and how he overcomes his own ego to become a better fighter and a better person. His relationship with Bulma and his rivalry - turned - friendship with Goku are rich areas to explore in fanfiction.
Goku is often a very popular character in fanfiction. His never - ending pursuit of getting stronger and his iconic Super Saiyan forms make him a great focus. Writers love to put him in new and challenging situations, like facing off against a super - powerful, self - created enemy.
