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.
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.
It's quite accurate. The anime version of Trigun Stampede mostly adheres to the manga, with just a few minor differences that don't significantly impact the main plot or character development.
I think it does to a large extent. There might be some minor tweaks here and there, but the core plot and characters are pretty much in line with the manga.
Trigun Stampede takes some liberties compared to the manga. It changes certain story elements and character traits to offer a fresh perspective, but this might not please all manga purists.
