Critical reception to the character has been positive. "Anime News Network" stated Vash seems to have been influenced by Western films and compared him with Himura Kenshin from the "Rurouni Kenshin" manga because of their pacifism. "Manga Life" compared Vash's way of life with that of the American Midwest in the 1800s. They called his characterization "fantastic" based on the personality he displays when facing enemies as he refuses to murder anybody. When more of the character's past is revealed because of his conflict with his enemies, "Manga Life" said Vash's true self makes him more engaging, something which is expanded by the artwork. Vash's reintroduction in "Maximum" drew positive comments with a reviewer from "Mania Entertainment" saying both new and existing readers would be attracted by the restart of Vash's journey after moments of peace. In a later review, however, "Mania Entertainment" said some events that happened to Vash might come across as repetitive because his pacifism keeps backfiring and no proper solution has yet been given. As Vash's philosophy was tested in the finale, "Fandom Post" praised the consequences of his actions. "BlerdsOnline" noted Vash got so much grief the reader would also feel it when reading the manga.
