* The VHS/DVD release of ''WesternAnimation/AGoofyMovie'' contained the ''WesternAnimation/GoofTroop'' episode "Calling All Goofs". The DVD also included the ''[[Series/WaltDisneyPresents Disneyland]]'' special "The Goofy Success Story".

* The first season of ''Series/{{Dollhouse}}'' was originally signed to thirteen episodes for the broadcast run as well as the DVD set. However, this included the pilot episode, which {{FOX}} decided was too confusing and didn't get into the action quickly enough, and so they didn't run it. Therefore, the episode count for the broadcast run was reduced to 12. However, delivering just twelve episodes would violate the contract they had with the company putting out the [=DVDs=], so a stand-alone thirteenth episode was created strictly for the DVD. As a result, the DVD set has fourteen episodes: the twelve episodes broadcast, the stand-alone thirteenth, and the original unaired pilot.

* The DVD release of ''WesternAnimation/LiloAndStitchTheSeries''[='=]s [[GrandFinale finale film]] ''WesternAnimation/LeroyAndStitch'' contains the then unaired episode "Link" as a bonus feature. It aired as the final episode of the show the following month. This instance also notable because this episode is one of only five episodes that were legally released for home video in the United States, and is also the ''only'' one that is still available to purchase in [[Franchise/LiloAndStitch the franchise's]] home country to this day.

* ''WesternAnimation/SpongebobSquarepants''

If the 13th episode is part of the original showing instead of a bonus, the group is called a ''Cour'' (french for 'a run').

* ''WesternAnimation/TeenTitans'' put a "lost episode" as an extra for the DVD movie. It explained a secondary season 5 villain and was half as long as a normal episode so they couldn't put it on the air.
** This episode was also available earlier online, if you had a special code from a cereal box.

* Many ''WesternAnimation/{{Rugrats}}'' VHS releases from the mid-90s and early 2000s included episodes months (and in the case of "Dil We Meet Again", two years) before they would debut on TV. ''Dr. Tommy Pickles'' contained "Hiccups", "Autumn Leaves", and "Grandpa's Bad Bug", ''Angelica Knows Best'' contained "Word of the Day", and ''Make Room For Dil'' contained "Dil We Meet Again" and "Big Babies", and ''Christmas'' contained "Falling Stars".
** Other tapes would include (at the time) unaired episodes as the main feature and the previously aired episodes as bonuses. ''A Rugrats Vacation'' included "Vacation", ''A Rugrats Thanksgiving'' included "The Turkey Who Came To Dinner". ''Runway Reptar'' included the titular special, ''I Think I Like You'' included "Be My Valentine", ''Discover America'' included the titular episode, ''Kwanzaa'' included "A Rugrats Kwanzaa", ''Easter'' contained "Bow Wow Wedding Vows", ''Halloween'' contained "Curse Of The Werewuff", ''Christmas'' contained "Babies In Toyland", and ''Mysteries'' contained "Murmer On The Ornery Express".

* The [=DVD=] release of ''Anime/ParallelTroubleAdventureDual'' has an extra episode tacked onto the end that partially undoes some of the events of the show's GrandFinale.

* The DVD release of Anime/SaberMarionetteJ's SequelSeries has a 26th episode that focuses on the Marionettes new lives [[spoiler: as humans]]. Notable I'm that it wasn't broacast in Japan, but was broadcast in Latin America.

* Although it wasn't a TwelveEpisodeAnime, the final episode of ''Anime/ExcelSaga'' (Episode 26: "Going Too Far!") was submitted to air on TV. True to the parody nature of the preceding 25 episodes, #26 was a parody of gimmicky, shock-value final episodes; in addition to content that could have never aired in its timeslot, the episode also runs exactly one minute longer than normal. It was added to the Japanese and overseas [=DVD=] releases because it'd never get past the censors (which was the whole point).
* The ''Anime/UtaKata'' bonus episode gave some added conclusion to the end of the series, as well as ending on a HereWeGoAgain note.
* ''Anime/PleaseTeacher'''s bonus episode references two characters' "new" physical relation, despite previous implication.

* The DVD edition of ''Manga/ElfenLied'' features a 14th episode. [[spoiler:In this episode, the viewer can see how Lucy was caught.]]
* ''VisualNovel/HigurashiWhenTheyCry'' came with Nekogoroshi-hen (Cat Killing Chapter), a single episode scenario based on a light novel.

* ''Anime/{{Kamichu}}'' has ''four'' bonus episodes. Yes.
* ''Manga/{{Sola}}'' was already thirteen episodes, but it still got two bonus episodes. Only one was fanservicey. The other was set before the first episode of the broadcast.
* ''LightNovel/{{Baccano}}'' is another thirteen episode series. It got three DVD-only episodes that, due to [[AnachronicOrder the nature of the series]], retroactively fit into the story.
* The ''Anime/CowboyBebop'' movie could be considered to be a two-hour long bonus episode, as it takes place within the continuity of the series despite being made after the series had ended.
* ''Anime/NanakaSixSeventeen'' has a bonus episode that doubles as a DayInTheLimelight, as it focuses almost entirely on secondary character Amemiya rather than either of the main characters.
* The fourteenth episode of ''Manga/HidamariSketch [[OddlyNamedSequel2ElectricBoogaloo X365]]'' is a DVD-only release.
* Not a TwelveEpisodeAnime example, but the first season of ''VisualNovel/{{Clannad}}'' gave us [[EnsembleDarkhorse Tomoyo's]] OVA, her route in animated form.
** ''~After Story~'' gave us Kyou's OVA.

* ''Manga/KOn'' gave us episode 14 in the final Blu-ray. It followed the girls New Year's Eve, but with an new twist not in the manga; They performed at a local Live Show. After all that was done, the episode shifted back to following the Manga at the end.
* ''Anime/SoundOfTheSky'' has two episodes exclusive to the [=DVDs=]. One of them involves the underage cast being UnsuspectinglySoused.
* ''Anime/AngelBeats'' will have additional episode included in 7th Blu-ray release.
* ''LightNovel/{{Durarara}}'' gets two extra chapters available only on DVD. One of them is episode 12.5, which features a wacky mix of red bags (and Mikado's group in a pretty ridiculous situation); while chapter 25 includes a full battle between Izaya and Shizuo. (Mikado and Anri end up in a pretty awkward situation, and Celty is chased once again by the cops.)

* ''Anime/GreenGreen'' had a 13th episode that upped the sexual content to straight-up hentai. This episode was not licensed for the dub.
* ''VisualNovel/{{Shuffle}} Memories'' came with an unrelated 13th episode that put the main cast in the World of Gods on a fishing trip.
* ''Anime/JewelpetTwinkle'''s 53rd episode is a 28 minute long OVA with new opening and ending sequences which is included in the Blu-ray box set release of the series. It's centered around the adaptation of a character, previously residing in Jewel Land, to the human world, and so it's less humorous and more of a character study than most other examples on this list.
* ''LightNovel/SundayWithoutGod'''s bonus 13th episode is divided into three parts, with the first part taking place between episodes 9 and 10, and the second and third parts taking place before the series.
* ''Anime/IlSolePenetraLeIllusioni'''s bonus 14th episode serves as a prequel, showing more of the bond between Akari and Fuyuna, and how Luna got started as a magical girl.

* The HotSpringsEpisode of ''Manga/DearS''. Labeled "Episode 9.5," it was an excuse for massive and gratuitous {{fanservice}} and LesYay.
* ''LightNovel/CatPlanetCuties'' has a post-season episode where the main characters play a variety of "[[StripPoker strip]]" party games.

* ''Franchise/AceAttorney'': When the first game was originally released in Japan on the Game Boy Advance, it only had four cases. Two games later, the trilogy was ported to the Nintendo DS then localized, and the first game recieved an extra case titled Rise from the Ashes. Because it was written after the first three games were released, it contains [[CallForward several hidden references to the later games]].

* The DvD release of Anime/SaberMarionetteJ's SequelSeries has a 26th episode that focuses on the Marionettes new lives [[spoiler: as humans]]. Notable I'm that it wasn't broacast in Japan, but was broadcast in Latin America.

* ''WesternAnimation/TheSimpsons'' had its first seventeen seasons and its twentieth season made available on home media before production of further season collections ceased in order to focus on making the show available on streaming services. However, two episodes that aren't part of those seasons escaped this fate due to the virtue of this trope -- Season 23's "[[Recap/TheSimpsonsS23E9HolidaysOfFuturePassed Holidays of Future Passed]]" can be found on the Season 16 Blu-Ray, while Season 25's "[[Recap/TheSimpsonsS25E13TheManWhoGrewTooMuch The Man Who Grew Too Much]]" can be found on the Season 17 Blu-Ray.

* Both the ''FreaksAndGeeks'' and ''Series/{{Undeclared}}'' DVD sets contained unaired episodes.

* The complete set of ''DrKatzProfessionalTherapist'' gives us three episodes that were unaired in the U.S.

* The DvD release of Anime/SaberMarionetteJ's SequelSeries has a 26th episode that focuses on the Marionettes new lives [[spoilers: as humans]]. Notable I'm that it wasn't broacast in Japan, but was broadcast in Latin America.

* The sole season of the animated cult series ''{{Downtown}}'' was eventually released on a two-disc set by the creators. The DVD included the "bonus" Halloween episode, which never got aired during the original run - but was shown in various non-US countries when it ran in syndication.
