History Fanon / SuperMarioBros

* Fans typically consider the Nintendo DS remake of ''VideoGame/SuperMario64'' to actually be a direct sequel to the original, plot-wise, due to its vastly different story.. It helps that nothing exists to deny that both games happened in the same canon so far.

** While not confirmed in canon, many fans have widely accepted the theory of 9-Volt having inherited a good chunk of his Nintendo collection from 5-Volt. Especially since a lot of his collection is stuff that would have come from her childhood (Such as the UsefulNotes/NintendoEntertainmentSystem, the UsefulNotes/GameBoy, etc) and that she, like her son, is also [[Main/LikeFatherLikeSon a gamer who is shown to be very fond of Nintendo herself]], even stating that the games in her collection in ''Gold'' (Which of course are Nintendo related) are all games that she has played in her childhood.

* Rosalina is sometimes depicted as related to Peach but what the relationship is depends on the person. She might be Peach's older sister, she might be an [[AlternateSelf alternate version of Peach]], or her mother, or her ''daughter'' from an AlternateTimeline or previous version of the universe. The most "plausible" relation is the idea that Peach is descended from Rosalina's brother (who was mentioned in the [[VideoGame/SuperMarioGalaxy storybook]]), which would make Rosalina Peach's great-to-the-nth-power aunt. The only thing supporting this theory is young Rosalina's crown, which implies she was a princess of something at one point, and the fact she lived near a castle. Canonically, [[WhatCouldHaveBeen Rosalina was indeed to be related to Peach in some way]], but Miyamoto vetoed it, and it was never elaborated what said relation would have been.

* Stanley from ''Donkey Kong 3'' is Mario and Luigi's cousin.

* Regarding the visual differences between DK Island in the Creator/{{Rare}} and DK Island in the Creator/RetroStudios-developed titles, the common fan theory is that the Kongs decided to move away from the original DK island to get away from the Kremlings after their past attempts to kidnap the Kongs and their bananas, on top of nearly destroying their original island. This also works as a convenient InUniverse explanation as to why the Kremlings don't appear in the Retro-developed titles.

* While it's not confirmed, many fans theorize that Azalea from the ''Mario Golf'' handheld games is related to Daisy, if not her sister, due to both girls having nearly-identical appearances and color schemes (particularly after Daisy was redesigned in 2002, which has her gain a short hairstyle similar to Azalea's).

* Let's not forget the idea that the "modern" Mario, born in the Mushroom Kingdom as seen in ''[[VideoGame/SuperMarioWorld2YoshisIsland Yoshi's Island]]'', is the son or grandson of [[VideoGame/DonkeyKong Jumpman, the "original" Mario]]. This seems derived from Rare's ''VideoGame/DonkeyKongCountry'' series -- in which DK's elderly [[DependingOnTheWriter father or grandfather]] Cranky claims to be the original Donkey Kong who fought with Mario, a claim that is reiterated during [[https://www.youtube.com/watch?v=506GBPVZ4So one of Snake's Codec calls]] in ''VideoGame/SuperSmashBrosBrawl''. ''VideoGame/YoshisIslandDS'' seems to support this idea by having Baby Donkey Kong, implied to be the modern version of the character, appear alongside Baby Mario. On the other hand, ''VideoGame/SuperMarioOdyssey'' [[{{Jossed}} throws a wrench in this]] by having Pauline, who should be middle-aged or older according to this fanon, appear alongside Peach for the first time. Perhaps unsurprisingly, the idea that this Pauline is also the daughter or granddaughter of the original Pauline has sprung up from people who want to keep using this fanon. Pauline is sometimes considered a relative of Mario and Luigi because of this fanon, but it's not universal, since some people want to be able to still ship Pauline and Mario.

* It's not uncommon for fan works, mostly Bowser/Peach ones, to make Peach the biological mother of Jr or even all the Koopalings.

* An incredibly common fanon regarding Peach's name is the idea that Toadstool (her old [[DubNameChange English name]]) is the name she uses formally, whereas she uses Peach for more casual situations. However, this was never the case officially. Canonically, she is only referred to as Peach (or Toadstool in the early English titles), regardless of the context or situation. Alternatively, Toadstool is often used as her last name, even though the only game to suggest that was the English version of ''64'' and was never acknowledged again afterwards, as the name Toadstool effectively became retconned in favor of Peach, outside of rereleases and remasters of old titles. The idea that Toadstool is Peach's last name has [[OlderThanTheyThink hinted at since before the name change]]. [[AllThereInTheManual Non-game materials]] include relatives like King Toadstool and Grandma Toadstool, and ''WesternAnimation/TheSuperMarioBrosSuperShow'' has an incident where she refers to herself as "[[TranslationNod Princess P]]."

* It was common for Rosalina to be presented as TheStoic, TheWomanWearingTheQueenlyMask, or an EmotionlessGirl. However, with appearances in series like ''VideoGame/MarioKart'', that's changed. She's still depicted as more [[ProperLady regal]] than other characters, though.

* The widespread belief that the Mario Bros. originated in Brooklyn and ended up in the Mushroom World through a freak accident. ([[DelusionConclusion Or simply hallucinated the whole thing]]). The Marios being from Brooklyn was [[https://www.destructoid.com/20-year-old-japanese-mario-64-interview-finally-gets-translated-388720.phtml canon in Japan]] at the time of Mario 64's development and [[http://uproxx.com/gammasquad/2014/08/mario-character-guide-1993-yoshis-real-name/ was adopted as canon by Nintendo of America in the 1990s]], but the accident portion originated from the cartoons and was used in the movie. Meanwhile, the ''VideoGame/YoshisIsland'' series of games flat-out state that the Mario Bros. were born in the Mushroom Kingdom, with fans reconciling the varying backstories by deciding they were born in the Mushroom Kingdom but grew up on Earth after infancy. Since ''Odyssey'' canonized Metro Kingdom, fans have since changed the idea so that the brothers were born in the Mushroom Kingdom and moved to New Donk City as kids, then moved back as adults.

* Many fan arts of Daisy depict her with either a tan or as AmbiguouslyBrown, much like her appearance in the N64 era, to go along with the ([[CommonKnowledge somewhat misguided]]) fact that she lives in a desert. Interestingly enough, starting from ''Mario Golf: Super Rush'', Daisy went back to having a tan.

** The ''VideoGame/MarioAndLuigi'' series shows the Bros. eating the various mushrooms (including the Mega Mushroom in ''Paper Jam'') but the Fire Flower simply activates on contact, exploding into sparkles in the later games.

** In fan fiction that uses the concept, an often-repeated idea is that Mario and Luigi are normal humans that get their special abilities from being in the Mushroom Kingdom, and that the same could apply to other humans from the real world. At its most basic, it extends to them jumping higher due to lower gravity. The ''Film/SuperMarioBros'' movie had a different but similar idea with the jump-boots the Bros get. This wasn't actually the case in the few games that treated the Brooklyn origin as canon, they'd simply always been able to jump like that.

* Most fans believed the manual for ''VideoGame/SuperMarioLand2SixGoldenCoins'' stated that Wario hired Tatanga to kidnap Daisy as a distraction when neither the game or the manual mentioned such a thing. This was even listed on [[Wiki/{{Wikipedia}} the Other Wiki]] for a while.

* To parallel Mario and Luigi, Wario and Waluigi are brothers. Various official sites and magazines/promotional events for Nintendo games have actually called them brothers, as do licensed guides from Prima, but it constantly [[FlipFlopOfGod flip-flops]]. In ''VideoGame/MarioParty 5'', pairing the two creates the team name "Wicked Bros." The thing that makes this only a possibility and not definitive proof? Less/non-related characters can also sport names to the tune of Adjective Bros. Really, the surprising thing is just that "Wicked" isn't usually used as their last name based off this. The trophy gallery in ''VideoGame/SuperSmashBros Melee'' claims that Wario and Waluigi's relation to each other is unknown, though admittedly Smash Bros trophies are known to make mistakes.

* Several games have had single Magikoopa characters/enemies which were nameless or seemingly generic, but the fandom has universally decided that they are all Kamek. Some examples include the Magikoopa who was going to be in ''VideoGame/MarioKart64'' but was replaced with Donkey Kong; the Magikoopa who blasts Mario away from Peach's Castle in ''VideoGame/SuperMarioGalaxy'' (a Prima trading card for ''SMG'' confirms that it was indeed Kamek out of Japan); the Magikoopa who aids Bowser in ''VideoGame/MarioAndLuigiBowsersInsideStory'' (confirmed to be him in the remake's ''VideoGame/BowserJrsJourney'' mode); and the Magikoopa who was a boss in ''VideoGame/YoshisSafari''. One game, ''VideoGame/SuperMarioRPG'', does have Kamek in it, but he was unnamed or misnamed in the English versions. Bizarrely, ''[[VideoGame/MarioParty Mario Party DS]]'' has him named Kamek, but in ''Mario Party 9'' he is named "Magikoopa" in the North American version... yet not the European version. Much of this confusion comes from Kamek not having a unique name in Japan outside of the aforementioned Mario RPG, where he was named Kamezard. Furthermore, in most appearances, Kamek is identical in appearance to a generic Magikoopa. Essentially the only way to tell for sure if it's Kamek is if a ''VideoGame/YoshisIsland'' reference is made.

* After the events of ''VideoGame/WarioWorld'', Wario would shift away from living in a castle in favor of living in a house. While there is no official answer to this, the common theory amongst fans is that he still has the castle, but it isn't his primary living quarters, with his castle instead becoming a secondary/summer home for when he wants to get away from the city.

* Regarding the visual differences between DK Island in the Creator/{{Rare}} and DK Island in the Creator/RetroStudios-developed titles, the common fan theory is that the Kongs decided to move away from the original DK island to get away from the Kremlings after their past attempts to kidnap the Kongs and their bananas, on top of nearly destroying their original island. This also works as a convenient InUniverse explanation as to why the Kremlings don't appear in the Retro developed titles.
* Cranky is usually depicted to have a understandable grudge against Mario for defeating him in the original arcade game and then caging him up in ''Junior''.

* While their canon relationship is that of a antagonistic rivalry, some like to theorize that Captain Syrup has lingering romantic feelings for Wario.
* After the events of ''VideoGame/WarioWorld'', Wario would shift away from living in a castle in favor of living in a house. Fans have three common theories for why Wario's castle would disapepared. (A, It was somehow destroyed off-screen, (B, the worst ending of Wario World (in which Wario gets a tent) is the canonical ending, or (C, he still has the castle, but it isn't his primary living quarters anymore, with his castle instead becoming a secondary/summer home for when he wants to get away from the city.

** While the two don't interact much in canon and their exact relationship is unknown (though the one interaction they did have (which was on the ''Smooth Moves'' blog) was friendly, implying they're on good terms), Ashley and Penny are portrayed as having a close relationship in fanworks. What that relationship is exactly tends to vary across the fandom, varying between them being [[ScienceVsMagic rivals]], [[OddFriendship friends]], or [[OppositesAttract even]] [[LesYay lovers]]. ''Get It Together'' would subtly lampshade this idea by having a Wario cup purely dedicated to the two.

** As a bit of a compromise between her original and ''Gold'' designs, Penny is sometimes depicted in fanart with heterochromia (which she lacks in canon), with one being brown like her original design and the other being blue like her ''Gold'' design.

* While their canon relationship is that of a rivalry, some like to theorize that Captain Syrup has lingering romantic feelings for Wario.

* Elsewhere in the 'verse, the ''VideoGame/WarioLand'' games have a recurring PirateGirl named Captain Syrup. The games have never confirmed the assumption that her first name is [[PunnyName Maple]].

* Ashley from ''VideoGame/WarioWare'' is usually interpreted as being a young girl due to the fact she [[ArtisticAge looks like a little kid]] (she also sounds like one too in the earlier games), rather than the teenager she's stated to be in the Western localizations. As part of this, UrbanLegendOfZelda states that she's 8-10 in Japan but was aged up overseas for... some reason, but in reality, her age is [[VagueAge never even stated]] in Japanese material.

* Toad and Captain Toad are two separate characters, but a lot of fans like to make them one and the same, especially since the two are never seen together, and some early materials did identify them as the same character.

* The Volts from ''VideoGame/WarioWare'' have quite a bit:
** 18-Volt and 9-Volt are family, usually brothers. In his debut, 9-Volt's teacher comments that 18-Volt has "no relation to naughty 9-Volt".
** Some fans believe 18-Volt is slightly mentally disabled or autistic as a way to explain how he's still in 4th grade despite looking like an adult. Alternatively, he's YoungerThanTheyLook.
** Due to her skill and how big games are in the Volt household, some like to portray 5-Volt as a Let's Player, video game journalist, or Indie Game Designer as a way of supporting her family. The last one ended up being true to some extent: starting with ''[=WarioWare=] Gold'', she became employed at the game studio [=WarioWare=], but to what capacity isn't clear..
** The numbers in their names are usually regarded as some indication of age: 9-Volt is 9, 18-Volt is either also 9 (explained away as 9×2 due to his size) or 18, and 13-Amp is 13. 5-Volt is the only anomaly since she's an adult, though some take the number to be the age she got into Nintendo games.
* Due to its name, some speculate that Diamond City from the ''VideoGame/WarioWare'' games is located in Jewelry Land from ''Yoshi's Safari''.

* Tiny Kong is the only Kong who has developed much, if at all, since their debut game. Not even her older sister, Dixie Kong, looks like she's grown older. To explain this, Tiny Kong is YoungerThanTheyLook. She's 13-15 (or the Kong equivalent), but she hit a large growth spurt.
