History Fanon / PuellaMagiMadokaMagica

* Homura's [[spoiler: timeline count.]] In the series, it's shown to be five at the least. Though it's a point of debate among the more technically-minded fans, most fanfic writers take a more dramatic approach, suggesting anywhere from [[OlderThanTheyLook several dozen]] to [[ReallySevenHundredYearsOld several hundred,]] with some heading into [[TimeAbyss the thousands.]] Stories that don't provide a count still often show her acting as if [[spoiler: resetting the timeline]] is almost meaningless to her. No matter which way, they all seem to agree that the ones seen in the series were only a very small fraction of what she went through. WordOfGod confirmed this to a degree, claiming that it was "approaching 100." The lowest number that tends to appear in fan discourse is around 14, based on how many [[spoiler: strings are seen around Madoka at one point]] as well as Act Zero, though this is the minimalist count and the latter is considered to be a distinct story from that of the main series.

** On a less extreme note, the idea that Homura specifically saves the cat from the opening [[spoiler: to ensure it can't be run over and save it so Madoka doesn't make a wish to revive it]] is a common concept that would be shown in an official work in ''Act Zero''.

* The idea that the constant [[spoiler: time travel trips Homura made]] supercharging not just Madoka as per canon, but also the rest of the main cast is a popular theory, particularly used to explain certain factors in ''Rebellion'' involving Homura. An idea that this was what allowed Sayaka [[spoiler: to become a Magical Girl when she hadn't in the first timelines]] was a popular theory, though Act Zero would imply other explanations.

* The reason that Magical Girl costumes look the way they do isn't explained in series, only hinted at via Madoka's doodles of her own possible Magical Girl outfit she makes in the second episode that look very similar to her eventual outfit. However fans generally assume, much like in other Magical Girl series like ''Nanoha'' and ''Miraculous Ladybug'' that the costumes are, to various degrees of intent, conscious creations of the Magical Girl in question based in their own idea of what a Magical Girl should look like.

* Are magical girls [[TheAgeless immortal]]? The series is pretty ambiguous on the issue; Mami and Kyoko both age, but Homura doesn't (though her powers could be a factor). A great number of fans, though, have suggested that magical girls have some form of eternal youth, either being able to freeze their age or being ageless as a consequence of having [[spoiler: a body that's already dead]]. Not helping is the canon itself being vague on this point: in ''[[VideoGame/MagiaRecordPuellaMagiMadokaMagicaSideStory Magia Record]]'' [[spoiler:19-year-old Mifuyu is pushed into joining the Magius because she believes she's getting weaker as a result of aging]], meanwhile in ''[[Manga/PuellaMagiTartMagica Tart Magica]]'' the character of [[spoiler:Perenelle Flamel]] does not have an explicitly stated age but can be calculated from her date of birth in real life to be 108 years old [[OlderThanTheyLook despite appearing no older than 30]] and it's implied she's even older than that, with Magia Record implying she, alongside [[spoiler: Elisa and Melissa, are still alive in the present day]], while [[spoiler: Mifuyu's]] concerns are countered by similar Magical Girls in ''Magia Record'' who lack this issue despite a similar age and tenure and implications magic loss is more a result of mindset (like Kyoko's loss of illusion powers) than anything inherent to age, [[spoiler: which events in Act 2 support]], and members of the Tokime Clan are descendants of at least one Magical Girl, meaning that Magical Girls are still able to have children.

* Homura's [[spoiler: timeline count.]] In the series, it's shown to be five at the least. Though it's a point of debate among the more technically-minded fans, most fanfic writers take a more dramatic approach, suggesting anywhere from [[OlderThanTheyLook several dozen]] to [[ReallySevenHundredYearsOld several hundred,]] with some heading into [[TimeAbyss the thousands.]] Stories that don't provide a count still often show her acting as if [[spoiler: resetting the timeline]] is almost meaningless to her.

The lowest number that tends to appear is around 14, based on how many [[spoiler: strings are seen around Madoka at one point]], though this is the minimalist count.

* They're all lesbian. No exception. The fanon especially leans towards Homura (for crossing the "Ambiguous Relationship" line with Madoka too many times to count) and Kyoko (the tough tomboy who changed her whole attitude and [[spoiler: eventually gave up her life]] for [[spoiler: Sayaka]]. When it comes to those who are attracted to guys (but also pretty much always also attracted to girls), that list tends to include Sayaka (who canonically is interested in Kyosuke, though writing her as being oblivious to the fact she actually has no romantic interest in boys is not unheard of in fanfics) and Mami. Madoka tends to fluctuate, though it is rare to have her not be in a relationship with Homura or another girl in most works that aren't deconstructive.
** While often not a magical girl herself, Hitomi tends to be seen as one of two ways and one is that of someone who is attracted to girls as well but [[TransparentCloset so far in the closet it doubles back into becoming obvious]]. The other end, typical of RonTheDeathEater treatment, makes her a HeteronormativeCrusader.

* While there is some hints in canon that [[spoiler: the timelines that Homura jumps to are not completely identical to each other without the butterfly effect]], as for example one has some hints [[spoiler: that Kyosuke played guitar in one timeline instead of violin]], often fanworks will increase the differences between them to put Homura in [[spoiler: various strange, whacky hijinks to either establish sufficient changes to bring on a different ending, or just to put Homura in unusual situations for a bit of fun.]]

* The exact illnesses that Touka, Nemu, and Ui were suffering from prior to Iroha's wish [[SoapOperaDisease were never identified in canon]] beyond a few symptoms and the fact that the three were in long term care prior to Iroha's and their own wishes, with only a few traits identified like Touka hyperventilating and restricted diets. Fanfics will give them an explicit or general diagnosis as the story demands, though a slight trend tends to somewhat ironic conditions with [[InsufferableGenius Touka]] having a brain condition, [[JockDadNerdSon Nemu]] having a neurological condition, and [[TheHeart Ui]] having a heart condition.

* Magical Girls being able to use their true nature to [[TheNeedless stave off hunger, albeit at the cost of Soul Gem Corruption]], was common idea in fan stories that logically builds off how Soul Gems affect other ailments of the body such injury and illness that has come up in various canon stories prior to later parts of Magia Record confirming it.

* While no media has depicted Magical Girls being able to use their true nature to [[TheNeedless stave off hunger, albeit at the cost of Soul Gem Corruption]], it is a common idea in fan stories that logically builds off how Soul Gems affect other ailments of the body such injury and illness that has come up in various canon stories.

* The existence of Magical Girl gangs in other cities, often with squabbles with Kyoko she mentions being on the run from when she comes into the story. While eventually shown in ''Magia Record'' via Promised Blood, the idea predates them and was loosely based off groups like the Pleiades Saints, who did in fact have a history with Kyoko.

* The reason that Magical Girl costumes look the way they do isn't explained in series, only hinted at via Madoka's doodles of her own possible Magical Girl outfit she makes in the second episode that look very similar to her eventual outfit. However fans generally assume, much like in other Magical Girl series like ''Nanoha'' and ''Miraculous Ladybug'' that the costumes are, to various degrees of intent, conscious creations of the Magical Girl in question.

* The Incubators [[SupernaturallyValidatedTransPerson being perfectly able to grant wishes to trans girls and other non-gender conforming individuals]] has not been seen in canon, but is common in fan stories under the general note that A: it has not been disproven, and B: if the Incubators could do it, they would have no reason not to.
