Vash doesn't die. The manga's storyline keeps him alive through all the challenges and adventures. The creators chose to give him a different fate than death.
Definitely not. Vash is a figment of someone's creative mind. It has no roots in true events. The entire concept is built from scratch for the purpose of providing an enjoyable and imaginative experience for viewers and readers.
The relationship can be developed through shared experiences. For example, if they are in a life - or - death situation together, like being trapped in a collapsing building. Vash's protective nature towards Rem can shine through, and Rem can show her trust in Vash. Another way is through communication. They could have deep conversations about their pasts, their fears, and their hopes for the future.
Yes, there might be. It could be about Naruto somehow being a fan of Vash. Maybe in this fanfiction, Naruto discovers Vash's story and is inspired by his non - violent ways of dealing with enemies, despite having his own ninja way. He could try to incorporate some of Vash's philosophies into his own ninja world.
One common theme is Vash's struggle with his past. His actions in the past and the consequences they've had on him are often explored. Another theme is his relationships, like his friendship with other characters or potential romantic relationships. His pacifist beliefs are also a big theme, and how he tries to uphold them in different situations.
One great Vash the Stampede crossover fanfiction is the one where he crosses over with the Cowboy Bebop universe. It's really interesting to see how Vash's pacifist nature clashes and also meshes with the more morally ambiguous characters in Cowboy Bebop. The author does a great job of maintaining Vash's character while exploring new storylines in the Bebop world.
