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.
There was a lot of controversy about the strongest villain in Dragon Ball. Different search results mentioned different villains, including Ratize, Fliesa, Buu, Sharu, Dr. Gro, Zamas, and so on. Since there was no clear and unanimous answer, it was impossible to determine who the most powerful villain in Dragon Ball was.
The Saiyan Saga is quite memorable. It introduced the Saiyan race to us and the threat they posed to Earth. We got to see Vegeta and Nappa land on Earth, and the Z - fighters had to fight for their lives. Goku's return and his battle with Vegeta was epic.
The most unforgettable villain in Dragon Ball MT was Babe. If you are a fan of Dragon Ball, you might want to try reading the book "Dragon Ball: Attack of Ratize" written by the author, Darknorth Fishbird. The main character fought Babe once. I hope you like this fairy's recommendation. Muah ~😗
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.
One of the interesting power - ups could be his Ultra Instinct form. In fanfiction, it might be further enhanced, like having different levels that are not shown in the original. For example, he could have an Ultra Instinct - Kaioken combination which would be extremely powerful.
A popular version of Bardock in fanfiction is the one who has a premonition of the destruction of the Saiyans much earlier. This Bardock then tries to take actions to prevent it, like gathering other Saiyans who might be sympathetic to his cause. It makes him a hero figure right from the start, rather than just a victim of Frieza's wrath as in the original story.
One of the most interesting storylines is Goku's journey to become stronger. His constant battles and training to protect the Earth are really engaging.
Bulma is a memorable character too. She's smart and resourceful. She invents a lot of useful gadgets throughout the series. Without her, the search for the Dragon Balls would be much more difficult. Also, Krillin. He's Goku's best friend from childhood. His underdog status and his determination to keep up with the stronger fighters make him a character that fans remember.
One of the most exciting storylines is the Saiyan Saga. The appearance of Vegeta and Nappa, powerful Saiyan warriors, on Earth brings intense battles. Goku's fight against Vegeta especially is thrilling as they both push their limits. Another great one is the Cell Saga. The creation of Cell, an ultimate bio - weapon, and the Z - fighters' attempts to stop him are full of suspense.
