* BannedEpisode: "Hot Springs Planet Tenrei" never saw the light of day on America's Creator/{{Toonami}} block due to its excessive nudity and sexually suggestive content. Not even Creator/AdultSwim aired it during the show's short run there (though they simply re-aired the Toonami edits rather than making their own version[[note]]hypothetically, an Creator/AdultSwim cut of this episode would have some of the nudity unedited. Aisha ranting about wanting a hotter hot spring while naked would be affected, as would most of the stripping in Urt's booby-trapped video, but the rest of the nudity would more or less be intact[[/note]]). Over in the UK, the cartoon channel CNX attempted to air the episode, but a lot of cuts had to be made to pass the censors. This edit was too short and too messy to watch, so it was shelved. While most anime episodes with excessive fanservice that get banned from television are filler, "Hot Springs Planet Tenrei" was different. This episode actually was vital to the overarching plotline. The [=DVD=]s and online are the only places you can see this episode as it was originally (both in Japanese and English). However, this was [[https://twitter.com/Clarknova1/status/937414215920508929 finally averted]] in 2018 during the show's return run on Toonami. Complete with a TV-MA rating[[note]]During that run, the rest of the series oscillates between TV-PG and TV-14[[/note]], it aired entirely uncut, save for a few minor edits, such as Aisha's nipples being erased during the aforementioned scene.

* KeepCirculatingTheTapes: Now {{Averted|Trope}}. Along with every other Bandai-licensed show, the rights to Outlaw Star fell into limbo when the company went belly-up in 2011. It took some time, but eventually this show, along with a few other Creator/{{Sunrise}} shows, found a new home at Creator/{{Funimation}}.
