Vegeta is also very likely to be a hero in the new story. He has grown a lot throughout the Dragon Ball series and in DB Legends, he might play a crucial role in fighting new threats. His Saiyan pride and his determination to surpass Goku could drive the story forward in interesting ways.
Well, we might expect new characters to be introduced in the new story of DB Legends. This could include some fan - favorite characters from the Dragon Ball universe that haven't been in the game's story before.
I'm not sure specifically as there could be many interpretations. It might be a fan - created story about a girl and Gohan in relation to a red machine. Maybe it's a story where the girl has some sort of encounter or adventure with Gohan that involves this red machine.
Sadly, I have no idea which author wrote the 'girl in the red machine gohan fanfiction'. Fanfiction is often created by many different people all over the world, and this one could be by an amateur or someone who just wanted to explore this particular scenario with Gohan and the girl and the red machine.
The length of DB mangas differs. It depends on factors like the story's complexity and the author's vision. Some might run for just a few volumes, while others could have dozens.
