DB Heroes doesn't follow the manga exactly. It takes inspiration and builds on it, making changes to suit the specific requirements of the series. However, the core elements are still recognizable.
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.
The 'DB Cooper' story is about a man who hijacked a plane in 1971. He demanded a ransom of $200,000 and four parachutes. After getting what he wanted, he jumped out of the plane over the Pacific Northwest and was never seen again. It remains one of the greatest unsolved mysteries in American history.
Well, 'db crossover fanfiction' usually involves taking characters or concepts from different 'db' related works and mashing them up. For example, if 'db' means Dragon Ball, it could be about Goku meeting characters from another Dragon Ball - like series in a whole new adventure that wasn't in the original. It allows fans to explore 'what - if' scenarios and expand on the existing lore in their own unique ways.
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.
