Critical reception of "Zombiepowder." as a whole mostly deemed it mediocre and average. Two reviews from Anime News Network ranked it as a C, it received a C+ review from MangaCast, a Den of Geek review gave it 3/5 stars, and an IGN review concluded it was "no better or worse many other shōnen titles" with "not much to separate it from the massive stock of shōnen series that are similar to it." Jason Thompson included it in a list of "mediocre" shōnen action titles whose clichéd nature and "ripped-off" character designs left them interesting only to readers unacquainted with the tropes of the genre. The universal criticism in these reviews is that the series as a whole lacks originality, with most mentioning that it reads very much like the author's first effort it is, and would therefore appeal mostly to fans of the author. While he echoed most individual criticisms of the English-language reviewers, a divergent conclusion was reached by Russian critic Alexander Gorban of "Animemaniacs Magazine Online", who believes that "Zombiepowder."s fundamentals were all strong, and that the failure of the series in Japan was instead due to Tite Kubo's overreach in publishing a series in the highly-competitive "Weekly Shōnen Jump" at such a young age. Had the freshman author been serialized in a less prominent magazine, asserts Gorban, "Zombiepowder." would have been allowed longer to establish itself and could have developed into a series at least as good as "Bleach".
