, it's not just a random throwaway gag that pops up unexpectedly only to sink forever, it's a complete piece of continuity not thrown away, but still set aside. While it cannot participate

- Darker Than Black: OVA is a Deconstructive Parody on the series... with a Reset Button at the end.
- Detective Conan has an ongoing spinoff manga series called Detective Conan Special Edition that is going on on a children's manga magazine. While it agrees with most canon elements of the main series, it's not drawn by the original mangaka (and hence has some Off Model issues) and The Syndicate never appeared outside of the First Episode Spoiler. It's lack of firm link with the canon can be demonstrated by how, despite being a Long Runner itself (>30 volumes), its story were very seldomly adapted into the anime, even though such a thing would be very helpful in preventing Overtook the Manga.
- Many Pokémon movies - while a few of them are shown to be part of the canon, one wonders how the Victini movies would fit in, due to them being the same movie, but with different twists.
- In the early days of Magic: The Gathering, a number tie-in novels were published by HarperPrism and a comic series was published by Armada. When the Weatherlight saga began and Wizards of the Coast started its own novel line, the continuity was revised (This is commonly referred to as "The Revision"). Any material in the old publications is considered Canon unless new material directly contradicts it.
- This is the status of the Vertigo Comics line of DC Comics: it started as part of the DC Universe, with most if not all characters simply being mature readers takes on existing characters, but has grown progressively more separate (and also began introducing new titles with no connection to the DC Universe). Basically, a Vertigo story featuring a DC character only applies to the main universe IF a story in a DC comics says it did. For example, we know that Dream of the Endless exists in the DC Universe because he (or rather his replacement) has appeared in issues of Justice League of America and Justice Society of America. However the versions of Hell from those universes do not match.
- Though even those interpretations of hell remain as Loose Canon due to the fact that the Sandman series posits that there are multiple parallel afterlifes. In addition, for the most part, Vertigo depicts Hell as subjective; DC depicts Hell as objective.
- Given how most Sam & Max comics usually only last three pages and how most stories (including the cartoon and video games as well) are mostly standalone, an official canon for the overall franchise is a really hard thing to decipher. The only time continuity really comes into play these days is in the Telltale Games Sam & Max series and tiny references to past cases (like Jesse James' severed hand from Sam & Max: Hit The Road appearing in recent episodes of the Telltale Games Sam & Max.
- The 2003 film Hulk essentially is this to the 2008 film The Incredible Hulk. The latter picks up with the hero where we left off with him at the end of the previous film, but 'adjusts' certain elements of the back-story...although the specifics of that back-story have very little bearing on the plot of the film itself.
- Superman Returns also uses this regarding the first two Superman films, particularly as despite being set a few years after Superman II, it is seemingly set in contemporary times instead of during the eighties.
- It could be said that the Evil Dead films have this relationship. Each film streamlines and slightly alters the general events of the previous film before continuing the story from where it ended. Army of Darkness even replaces the closure of Evil Dead 2 to make its plot work better.
- The Pony POV Series has several chapters which Word of God has specifically said are optional for readers to consider canon or not, depending on their personal preference. This includes Luna's sidestory and the "Battle Pros" chapter. The former is refrenced somewhat in the actual canon, but never truly confirmed.
- Pinkie Pie's Side Story, detailing the end of the G3 universe through her witnessing the Cosmic Retcon that must be done or the universe ends. Word of God has pretty much left it up to the readers rather it's a prequel, a non-canon standalone story, or just a fever dream of Pinkie Pie.
- The Getting Back on Your Hooves sidestory "Another Happy Mother's Day" is said to be this by Word of God, being one valid possibility as to the fate of Checker Monarch. Ironically, it's actually a Recursive Fanfiction written by Alexwarlorn, the writer of the above Pony POV Series, the two authors being good friends.
- The LOST tie-in books and video game aren't canon (except for the Incident Room in the game...) but they don't interfere with canon by involving background characters and just mentioning the canon events as happening elsewhere. (The one trip-up spot here is really the part right before the end of the video game where you have to save Jack and Kate from the Others. There's no reason why that wouldn't come up again in the series...)
- Very common with TV series tie-ins in general. Most of the Buffy the Vampire Slayer and Angel tie-in novels are this way, as are the CSI: Crime Scene Investigation franchise tie-ins.
- The third-season The West Wing episode "Isaac and Ishmael" was specifically intended to be canonically vague - it opens with the actors telling us not to worry about where it fits into the show's chronology (which is wise, given that it falls in the middle of a cliffhanger and its resolution), but no one ever actually says that it isn't canonical.
- Doctor Who is often this, but most of these cases during the '60s and early '70s were due to the BBC wiping most of their tapes for storage - In short, from their view, the storylines they created were just as disposable as the episodes.
- Warhammer and Warhammer 40,000 have this for almost everything. Major events get retconned all the time, and it's up to individual writers what they consider canon for their story. Due to the sheer size of the setting and suspect in-universe sources of background info (which is generally presented as propaganda for one faction or another, making its reliability conveniently dubious) things they don't like can usually just be ignored and left ambiguous.
- The Drowsy Chaperone: In-Universe, Man-in-Chair never elaborates on the actors playing George and Trix. However, the booklet that comes with the 2006 Cast Recording contains fake liner notes from the record of the Show Within a Show, naming both of them.
- Metal Gear:
- Metal Gear Solid Mobile. It hits the Reset Button at the end by erasing Snake's memory so it doesn't interfere with canon. (Though that doesn't explain why Otacon doesn't remember any of the events either...) It doesn't help that it's so hard to get hold of that it's virtually a Missing Episode.
- In The Darkness Of Shadow Moses and The Shocking Conspiracy Behind Shadow Moses, in-universe backstory documents included with Metal Gear Solid 2, were both intended to be canon at the time, but have been ignored for convenience (particularly the plot point regarding Metal Gear possessing only a dummy warhead, the background information about "the real Naomi" who went missing in the Middle East and the fate of the main Naomi). That said, not much is specifically contradicted between the games and the books and some of the things that are contradicted are likely intentional. The stuff that isn't contradicted (like the background details of Nastasha and Ames' relationship) is presumably canon.
- Some of the "Snake Tales" shorts included with Metal Gear Solid 2 Substance - the stories are certainly not part of the main continuity, but some fill in background information that is probably canon:
- "Confidential Legacy" is the most obvious one - the story about Meryl working with Gurlukovich is definitely non-canon, but it also goes into a lot of detail about Meryl's family situation which is regarded as canonical, naming Meryl's legal father for the first time and delving into his military position and job. It also contains the only explanation thus far for why Snake and Meryl are not a couple in Metal Gear Solid 2.
- "Big Shell Evil" shows Snake demonstrating a photographic memory talent to memorise a long computer password. He never actually uses this ability in the canon, but there is still a very sad Call Back to it in Metal Gear Solid 4 in a sequence where the player may have him forget a computer password, demonstrating he has lost this ability. In addition to this, it elaborates on Snake and Otacon's friendship circumstances and interpersonal quirks, along with "External Gazer".
- "Dead Man Whispers" fills in a lot of detail about Vamp and Scott Dolph's relationship. The canon has Snake mention in an optional radio conversation that "rumour has it" that they were lovers. "Dead Man Whispers" makes it very clear that they both deeply loved each other, as Vamp is shown to sacrifice himself in order to protect Dolph. It also gives some characterisation to Jackson, the original leader of Dead Cell and Fortune's husband, and goes into detail about what exactly the financial corruption scandal he was involved in was.
- Metal Gear Solid: Portable Ops, not being made by Kojima, is canon only insofar as it doesn't contradict anything else.
- Metal Gear: Ghost Babel adds some detail to Big Boss's backstory (such as his student Augustine Eguabon) that was presumably supposed to be canon at the time, and gives a lot of background information and worldbuilding to Galzburg/Gindra, the country where Outer Heaven was located.
- Half-Life: Opposing Force (note that the expansions were made by a different company than original producers Valve) introduced the main character (marine Adrian Shepard) who proved quite popular among the fanbase; and the mysterious "Race X" from another, unknown world who happened to arrive at Black Mesa during the events of Half-Life and made a weak attempt to conquer Earth. Their canonicity is pretty much a gray area: it was never completely exiled from canon, but they did not appear in the series again. Same goes for Blue Shift; though Barney Calhoun made his way into Half-Life 2, the supporting characters (Dr. Rosenberg) and the exact events are semi-canon at best.
- A generic, unnamed guard in Half-Life offers to buy Gordon Freeman a beer if they leave Black Mesa alive. While Barney Calhoun appears in Blue Shift, he comments in Half-Life 2 that he still owes Gordon that beer. Calhoun never directly encounters Freeman during the course of Blue Shift, though it is conceivable that many guards (perhaps even all guards) owe Gordon Freeman a beer for some reason or other.
- The only detail from expansions that Half-Life's writer, Marc Laidlaw, has explicitly declared canon is Black Mesa's nuclear destruction in Opposing Force's ending.
- It is somewhat unclearly stated whether the Team Fortress 2 tie-in comic “Loose Canon” is in fact Loose Canon or not.
- Later comics and in-game updates build off of this comic as though it was canon, so it's only an example of In Name Only.
- In the Tales Series, the Tales of Fandom games are treated this way, at least by the parts of their audience that don't speak Japanese, due to No Export for You. Details may gradually trickle through the fandoms as Fan Translations are made, but since these can be unreliable, most fanfic writers consider them optional at best.
- Pretty much everything written by Michael Kirkbride for The Elder Scrolls lore outside of Bethesda is this. It's essentially treated as canon by most of the fanbase, but Bethesda has no official stance either way. Most of what he writes about is the more obscure aspects of the cosmology that doesn't get expanded on in the games, and lore figures the games never touch upon or that Bethesda is simply finished with (like Vivec).
- The Gunnerkrigg Court bonus pages at the end of every chapter represent two different varieties. Some of the pages just show brief scenes which are officially canon, but are rarely ever mentioned again. Other pages feature a white-haired girl named Tea who pops in to describe background details to the audience. The contents of her exposition are canon, but Tea has yet to appear in the comic proper, and she has interacted with a cartoon representation of Tom Siddell (a character that the real Mr Siddell insists is non-canon).
- The Order of the Stick comics that appeared in Dragon Magazine might fall into this. In one online strip where Haley mentions Belkar claiming to be a gourmet chef, he responds that it was in Dragon so he's not even sure if it's the same continuity.
- Templar Arizona: Bonus comics.
- Unwinder's Tall Comics:
- The Rant below page 32 specified that "It's not Tall Comics canon, but it IS Marmaduke canon." But fallout from the events of that page pop up again thirty pages later, anyway.
- Page 97 gives information about the in-universe authors of Powerup Comics. The rant below is quick to point out that this shouldn't be taken as absolute canon for Powerup Comics: "I mean, I consider it canon personally, and it's definitely Tall Comics canon that these are the real people behind Powerup Comics, but at the same time, I don't want to invalidate any fan theories about Powerup."
- After Homestuck ran an intermission featuring the Midnight Crew from Problem Sleuth, one member of the MS Paint Adventures forums began a forum-based adventure serving as a prequel to the intermission and starring the Midnight Crew's rival gang, the Felt. Although the author was eventually forced to cancel it due to accusations of forcing his fan fiction into canon, it was generally seen as this, especially due to the author getting permission from Andrew Hussie to use plot points and character designs that hadn't yet been featured in the main comic, and it was even given a Shout-Out by having Hussie slip a necklace resembling one worn by an Original Character from the forum adventure into the actual intermission. Andrew eventually declared it to be non-canon, however.
- Slapdash Application of Verbiage alternates between regular comics and "Tales of Dubious Canonicity", pieced together from previously-drawn artwork. Whether the events and dialogue of these comics have any bearing on the plot or characterization in the main comic is unclear.
- Questionable Content has a handful of characters who show up only in filler strips that the author writes when he doesn't have time to do a regular strip. However, he did write a multi-part New Year's comic with them, and one of them had a cameo in the comic proper. Oh, and there was also the birthday comic.
- In El Goonish Shive, according to the FAQ page EGS:NP stories "generally don't have continuity unless referred to in a later story, and aren't a part of the main storyline unless referred to in the story section." This means unless they involve things that obviously would not fit in continuity (like gratuitous Fourth Wall breaking) or explicitly say they are out of continuity (the Goonmanji storyline is a prime example) the EGS:NP storylines can be considered Optional Canon.
- Zuko's Story is a tie-in Prequel comic to The Last Airbender, the live-action film adaptation of Avatar: The Last Airbender. However, the writers went out of their way to incorporate details from the animated series. Except for Zuko and Iroh being drawn as their movie counterparts, the story would fit right in with the animated series, which was in fact the authors' intent. There is however no word on whether the series considers it to be canon.
- My Little Pony: Friendship Is Magic has the Comic Book spinoff which is of ambiguous continuity. As of yet, none of them flatly contradict the tvshow, but at the same time very little of what happens in the comics is referenced in the tv show, leaving it ambiguous whether the events of the comics are considered to have happened.
- Word of God from Hasbro states that the comic is considered canon until the cartoon says otherwise, such is the case with Daring Do. The comic started to hint that Daring was actually Twilight's mother. The episode "Daring Don't" revealed differently.
