** The American English dub, while staying mostly faithful to the Japanese version, has notoriously cut and edited the first two episodes of the Japanese version into one episode in the dub, effectively cutting out Atlas's origin story (meaning in the dub he wasn't introduced until later in the series and his past was only shown through flashbacks). The dub has been released on 2 separate DVD sets in different regions, a release in Australia by Madman, which along with all the dub episodes, including the first two uncut Japanese episodes with English subs. The other set released in the US by Manga Entertainment, while it had all the episodes in subbed and dubbed forms, the Japanese version of the first two episodes was cut like the dub version. While both DVD sets eventually went out of print, Creator/DiscotekMedia announced in March 2022 that they'd be coming to the rescue with a remastered Blu-Ray set that includes both the uncut Japanese version and the American English dub, with the Japanese version's episodes 1 and 2 and the American dub's spliced "episode 1" confirmed to be present.

Thus far, it is hard, if not impossible, for US fans to see the first two uncut episodes of the series. Unfortunately, both English DVD sets are out of print as of 2012.

* CreatorBacklash: According to a commentary on one of the 60's Astro Boy DVD boxsets, Osamu Tezuka hated one particular episode, "Midoro Swamp" aka "The Beast from 20 Fathoms". He farmed out the episode to a group of young anime/manga students, and the results dissatisfied him so much, that he personally destroyed every possible copy he could find. Unfortunately for him, a copy of that episode had already been shipped to the U.S. and dubbed (and would later resurface as a "Lost Episode" of the series on VHS), and the Japanese soundtrack (but not the footage) still exists and was included as an extra in the episodes release on the Astro Boy DVD sets.

* LateExportForYou: ''Astro Boy'' manga wouldn't be translated in English and released in the America until 2002 when Dark Horse Comics have acquired the rights. They also noted before they published the manga in that year, there's two unlicensed American comic adaptions that's not drawn by Tezuka, existed.
-->''"An American-style Astro Boy comic book was produced under the Gold Key imprint in 1965, but it was not drawn by Tezuka, and it was based on the animated TV show. In the 1980s, another ulicensed English-language Astro Boy comic book was created, but it too was not drawn by Tezuka. As a result, until the publication of the series by Dark Horse Comics in 2002, English-speaking fans of Astro Boy have had no way of knowing what the original manga story - the original Mighty Atom - was like."''

* KeepCirculatingTheTapes: Two story arcs from ''Mighty Atom Club'' magazine, "Jungle Devil Boundary" and "Chi-Tan", have never been reprinted (in Japan or otherwise).

* NoExportForYou: Only 5 episodes of the Japanese-language version have been released in North America as bonus features on the Right Stuf dub DVD releases, meaning that most of the episodes that weren't dubbed haven't come out in any version.

** And the English version cuts out even more episodes; only 104 out of the original 193 beast were ever dubbed. This is because the American dubbers had become increasingly worried about the violence in the show, America and Japan having taken Astro Boy in rather different directions, and a combination of fatigue over this and cultural differences in approach to animated stories (Japan wanted to resolve the story, America decided that 104 episodes was plenty to allow for reruns) resulted in the American studio cancelling its contract. Creator/OsamuTezuka himself had grown tired of working on Astro Boy and wanted to pursue other stories, hence why even the Japanese version ended at episode 193.

* MissingEpisode: Dub only - the 20th episode "Eternal Boy" has been omitted from release with the rest of the series in Digital and DVD form, mainly because the plot revolves around the Peter Pan story, which is still under copyright by Great Ormand Street Hospital in the US and UK. It was replaced with a clip show episode, with Tenma and Shadow discussing Astro's progress up to that point in the series.
