One common theme is rivalry - turned - friendship. Their initial intense rivalry gradually transforms into a deep bond as they face various threats. Another theme is power - up. They often find new ways to increase their power together, like in some fanfictions where they discover a new fusion technique.
The relationship could start with hostility. Towa might see Goku as a threat to her plans and Goku sees her as an evil force. But then, when they are forced into a situation where they need to rely on each other, like being stranded in a strange realm. They begin to see each other's strengths. For example, Goku might admire Towa's intelligence in dealing with the strange environment, and Towa might be impressed by Goku's unwavering determination.
One interesting story could be where Goku and Bulma go on an adventure together to find a new Dragon Ball. In this fanfiction, they face many challenges and along the way, they start to realize their feelings for each other are deeper than just friendship. It shows a different side of their relationship compared to the original series.
I really like 'Goku and Bulma's Unexpected Journey'. It has a great plot where they are thrown into a parallel dimension. There, they have to rely on each other more than ever. The author does a wonderful job of exploring their characters and how they interact in this new and strange situation.
The appeal lies in the combination of two strong characters. Goku is a well - known and powerful fighter, and Caulifla is a fierce and determined Saiyan. Their interaction can bring out exciting battles and interesting character development.
One popular story could be 'The Bond Beyond Rivalry'. It explores a deeper friendship between Goku and Vegeta as they face a new, extremely powerful enemy together. Their combined power and the way they start to understand each other on a more personal level makes it an interesting read.
One possible plot could be Goku and Turles forced to team up against a new, powerful enemy. Maybe a villain from another dimension that threatens both their home planets. This would force them to put aside their differences and combine their unique fighting styles.
One interesting fanfiction could be where Bulma and Goku have to team up to save the world in a unique way that wasn't shown in the original series. Maybe they have to travel to a different dimension together and face new enemies.
Their relationship could develop through mutual respect for each other's strength. Goku, being the pure - hearted Saiyan he is, might start to see that Turles has potential for good deep down. Turles, on the other hand, could be in awe of Goku's power and gradually change his view of Goku from an enemy to a rival and perhaps even a friend.
