* ActorAllusion: William Conrad is named after the character from the radio show Gunsmoke. He also bares a striking resemblance to Patrick Stewart.
* BigNameFan: Professional example. Scriptwriter Yosuke Kuroda was a ''huge'' fan of the Trigun manga and, in an unusual move for a series of this length, insisted on writing all 26 episodes himself. Nightow depicted him in the {{omake}} to [=TriMax=] Vol.2 and he's nearly as insane as Nightow.
* ChannelHop: The manga did this out of necessity. It began publication in ''Shonen Captain'', but the magazine shut down in early 1997, right before the story reached Fifth Moon and Knives's [[TheReveal reveal]]. After finishing the last chapter for the then-final collected volume to give the series some sense of closure (albeit a real DownerEnding), the story lay dormant for over a year before finally being picked up by seinen magazine ''Young King Ours'' and continuing as ''"Maximum"''.
** Amusingly, it was during this SeriesHiatus that JVC came knocking about making an anime. On the plus side, it allowed Nightow to be more involved in early development than a manga-ka would normally be.
* CreatorPreferredAdaptation: Yasuhiro Nightow '''''loved''''' the anime, largely ''because'' it was able to distill so neatly the manga's basic messages. He even drew the anime's filler characters into later manga chapters whenever an opportunity presented itself.
* FanNickname: Leggie or Leggah for Legato; Bashu (i.e. the Japanese pronunciation) for Vash; Wolfie, Wolf, Nico or Nick for Nicholas D. Wolfwood; sometimes Naibuzu (the Japanese pronunciation) or "Several Forks" for Knives.
* OvertookTheManga: An unusual example, as the anime was planned from day one to be 26 episodes, yet still caught up to the manga's story six episodes before the end despite being front-loaded with {{filler}}. The result was a defining example of AdaptationDistillation, as the final episodes contained the essential themes Nightow wanted to showcase but just hadn't gotten to yet.
* PortmanteauSeriesNickname: "[=TriMax=]" for ''Trigun Maximum''.
* ShowAccuracyToyAccuracy: Kaiyodo released an action figure of Monev in 2002 that proved popular with toy collectors. Only one problem - [[http://www.oafe.net/shocka/monev.php it only superficially looked like the character.]] The only bit that was accurate were the arm guns. The suit's color, the face mask and various details were altered and the muscle mass was sufficiently enhanced. It was really artistic license at play, since the rest of the toys were on-model. So why was it so popular regardless? The figure was 10 inches tall and massively articulated, plus it was imported to the US by Diamond, meaning a lot of people who had no familiarity with the series were buying it just because it was far beyond what most action figures of the time were like.
** [[http://www.oafe.net/yo/monev.php Then they made another version, this time in clear plastic.]] Actually, the only Monev toy to even halfway look like the character was the Kubrick block figure.
* TheOtherDarrin: The only voice actor to return to reprise their role for the movie's English dub was Creator/JohnnyYongBosch as Vash the Stampede. Jeff Nimoy and [[Creator/DorothyEliasFahn Dorothy Fahn]] were both interested in reprising their roles (of Wolfwood and Meryl, respectively), but Creator/{{Funimation}} replaced them behind their backs mid-negotiation. Lia Sargent was also replaced as Milly, but this was expected as she had retired from voice acting years earlier.
** The story gets crazier. Apparently Bosch, Nimoy, and Fahn originally approached Funimation with the position "You'll take all of us or you'll get none of us". After that, Funimation managed to get Bosch who had [[Manga/{{Beck}} worked with them before]] alone, and persuaded him to go to Texas anyway without telling the others. Unsurprisingly, Nimoy and Fahn were livid when they found out, and Nimoy (who has been surprisingly candid about the ordeal when asked) has said he finds it difficult to forgive Johnny. Note that the reason there was an impasse in the first place is because the terms Funi was offering were such that Nimoy and Fahn would have lost income.
* WhatCouldHaveBeen: Much like ''Manga/InuYasha'', ''Trigun'' was one of the Creator/AdultSwim anime shows that was meant for Creator/CartoonNetwork's Creator/{{Toonami}} block but ended up airing on [adult swim] instead due to content issues (in this case, it was due to the amount of gun violence that would have to have been edited down... and a few scenes got censored on [as] anyway)[[note]] The most notable cut made in the Adult Swim airing was in Episode 7, where Brilliant Dynamites Neon shoves his gun in Kaite's mouth and keeps it there for nearly 30 seconds.[[/note]]
** Oddly enough, ''Trigun'', along with the original 1963 ''Anime/AstroBoy'', was showcased during the April Fools Day 2012 Toonami broadcast, despite the two not having aired on Toonami before.
** Ever since Toonami was revived on [adult swim] hours, ''Trigun'' now has a chance to make an official premiere on Toonami (again, much like ''Manga/InuYasha'' before it). So far, however, it has yet to do so. Though considering ''Badlands Rumble'' was picked for their December movie marathon...
* WordOfGod: Nightow says that Kuroneko-sama is female. He has also provided Wolfwood with about half a dozen middle names to go with that 'D.'
** The best obviously being Dokonokuminomonjawaresumakinishiteshizumetarokakora, meaning "daily cigarette intake".
