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.
One popular trope is the 'fish out of water' trope. When Vash crosses over into another universe, he often has to adapt to new rules and cultures, which makes for some really fun and comical situations. For example, if he crosses into a modern - day Earth setting, his old - fashioned ways and his gun - slinging skills seem out of place but also really cool.
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.

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.
Overall, Trigun Stampede adheres closely to the manga. Some minor details might differ for the sake of the adaptation's flow and visual presentation, but the core remains the same.
A prevalent theme is the exploration of their different worlds colliding. Vash has his own world of being a gunman with a mysterious past, and Meryl comes from a more normal background. Fanfictions often explore how they bridge that gap. For instance, how Meryl gets used to Vash's erratic lifestyle, and how Vash adapts to having someone like Meryl care about him in a different way than others.
A possible plot could be that Vash's world and Naruto's world start to merge. Naruto meets Vash during this chaotic time. Vash is initially skeptical of Naruto's ninja ways which seem so violent compared to his own. However, as they work together to save both of their worlds from destruction, they come to understand and respect each other. Naruto, inspired by Vash's selfless nature, starts to change his approach to fighting, and this causes a stir in his own ninja community as they are not used to such a pacifist - like Naruto.
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.
