Fanon / Super Mario Bros.

Go To

Super Mario Bros. and its many spin-offs tend to be low on plot and characterization, leading fans to fill in the gaps.

  • A large amount of SMB Fanon originates from Lemmy's Land. Lemmy's Land has a fairly large, mostly serious fanfic section where most of the internet's SMB fanon spawns, while the "Scribbles" section is usually there to make a laughing stock of every Mario character. The "Interviews" often go both ways.

  • The tendency to use The Adventures of Super Mario Bros. 3 personalities of the Koopalings paired with the games' names for them is a pervasive piece of fanon, despite allusions to their canon personalities in Mario & Luigi: Paper Jam. In fact, these personalities are so popular that quite a bit of SMB fanfic is exclusively about the Koopalings!
  • The widespread belief that the Mario Bros. originated in Brooklyn and ended up in the Mushroom World through a freak accident. The Marios being from Brooklyn was canon in Japan at the time of Mario 64's development and 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 Yoshi's Island 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.
    • 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. Super Mario Bros. 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.

  • Let's not forget the idea that the "modern" Mario, born in the Mushroom Kingdom as seen in Yoshi's Island, is the son or grandson of Jumpman, the "original" Mario. This seems derived from Rare's Donkey Kong Country series — in which DK's elderly father or grandfather Cranky claims to be the original Donkey Kong who fought with Mario, a claim that is reiterated during one of Snake's Codec calls in Super Smash Bros. Brawl. Yoshi's Island DS 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, Super Mario Odyssey 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.
  • Whether or not Bowser has a last name — in Japan he's called "Koopa," but has been localized as "Bowser, King of the Koopas" since the instruction manual for the first game. The "King Koopa" name was used in the Super Show, and even after Super Mario Bros. 3, follow-up cartoons (and the movie) kept the name. It was clarified once or twice in The Adventures of Super Mario Bros. 3 ("I'm Bowser Koopa. King Koopa to you!"), but rarely in the games, which only makes things more confusing:
    • The Koopalings are all surnamed "Koopa" — but this arises from the localization. In Japan the characters didn't have names in their initial appearance in the Japanese Super Mario Bros. 3 manual and are only referred to by their first names during the Enemy Roll Call of Super Mario World(confusingly, taken from the U.S. localization of Super Mario Bros. 3''). Don't get us started on Bowser Jr.
    • Since one of the Koopalings' names is "Morton Koopa, Jr," following the American version of events suggests that Bowser's full name would have to be Morton Bowser Koopa, Sr. That or their mother was named Morton, which is even more confusing. This, of course, assumes that Morton Senior wasn't Morton Junior's grandfather, or they don't have an uncle named Morton... Basically, there has to be a Morton in that family tree somewhere. Or even more humorously, Bowser just named his son Jr. just to mess with people's heads. Since all of the Koopalings are named after musicians or people associated with music, Morton Koopa Jr. is most likely named after Morton Downey Jr. Some fans take this to be Bowser just named his kids after musicians he likes. In-universe, there's still no explanation, though.
    • Speaking of the Koopalings, Shigeru Miyamoto has stated that they are currently not Bowser's children, making them his minions and Bowser Jr. the only child, but fans are very slow to adopt this. This in turn renders Bowser being the father of the eight Fanon itself. However, it should be noted that this was originally NOT the case: this Japanese page has three different story descriptions for Super Mario Bros. 3 (two from Famicom and Super Famicom manuals, one from the backside of the cartridge box), and the Koopalings are called Bowser's kids in all of them. A fan theory makes them Happily Adopted by Bowser, which would make them technically not related to Bowser but his children nonetheless. Other fans see them as Bowser Jr's cousins. This was later Jossed in Mario & Luigi: Paper Jam, where Bowser treats them as bothersome minions, but even that hasn't stopped some fans.
    • From the Super Mario Bros. instruction booklet: "One day the kingdom of the peaceful mushroom people was invaded by the Koopa, a tribe of turtles famous for their black magic." So, the Koopa is the name of the species. Bowser is their king.
  • As for Bowser's wife, fanon states her name is Clawdia and she is the Missing Mom to the Koopalings, and often Jr. as well. Depictions differ on whether she's deceased or divorced. Less common, but "Clawdia" is also a name used for Bowser's mother. The name "Clawdia Koopa" comes from an old Urban Legend of Zelda that she was mentioned in a UK issue of Nintendo Power. Not only did that not occur, but Nintendo Power didn't exist in the UK.
  • It's not uncommon for fan works, mostly Bowser/Peach ones, to make Peach the biological mother of Jr or even all the Koopalings.
  • Most fans believed the manual for Super Mario Land 2: 6 Golden Coins 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 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 flip-flops. In Mario Party 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 Super Smash Bros. Melee claims that Wario and Waluigi's relation to each other is unknown, though admittedly Smash Bros trophies are known to make mistakes.
  • There's the tendency to assume that the Mario Bros. and the, uh, Wario Bros. are cousins. Officially, Mario and Wario have a rivalry that stretches back to childhood (when Mario was actually Wario's antagonist), but any relationship between the Good Bros. and the Bad Bros. is mostly speculation.
  • Another common assumption among fans is that Wart from Super Mario Bros. 2 is Bowser's brother, who was transformed into a frog somehow (the exact method varies from fan to fan, most being either a lab accident or that he was transformed by Bowser in a bid to get the throne).
  • Elsewhere in the 'verse, the Wario Land games have a recurring Pirate Girl named Captain Syrup. The games have never confirmed the assumption that her first name is Maple.
  • One item that is assumed, but only ever shows up in spin-off games, is best expressed by Brentalfloss' "Mushroom Kingdom":
    Mario! He gets mad superpowers
    from eating leaves and flowers...
    • Mario's power-ups in most of the series have usually been shown to activate on contact, and are also depicted this way in Super Show and its successors. Some early material, such as the Nintendo Adventure Books, depicted Mario eating power-ups; however they have multiple inaccuracies and are non-canon.
    • The Mario & Luigi 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.
  • There is a consensus that Mario and Peach were upgraded to First-Name Basis between Super Mario World and Super Mario 64. Between this period is when they really began becoming friends, and it is also considered when the romance between Peach and Mario really began. This fanon is used to explain why Peach suddenly went from going by her surname (Princess Toadstool) to her given name (Princess Peach) in-series. Later games partially contest this idea; both Mario & Luigi: Partners in Time and Yoshi's Island DS suggest that the Mario Bros. have been close to Peach since they were infants/toddlers. Partners in Time even sees Mario and Luigi invited to the castle for play dates with the baby princess.
  • Many fan arts of Daisy depict her with either a tan or as Ambiguously Brown, much like her appearance in the N64 era, to go along with the (somewhat misguided) fact that she lives in a desert.
  • To go with the above, Princess Daisy has all but moved from Sarasaland to the Mushroom Kingdom. Her tanned skin from the Nintendo 64 era went away because she's not in the desert anymore.
  • Peach and Daisy as cousins. Some strategy guides have called them cousins, but they're unofficial.
  • In the Japanese fandom, Count Bleck's father from Super Paper Mario is believed to be the chief of the Tribe of Darkness.
  • Rosalina is sometimes depicted as related to Peach but what the relationship is depends on the person. She might be Peach's older sister note , she might be an alternate version of Peach, or her mother, or her daughter. The most plausible relation is from the idea that Peach is descended from Rosalina's brother (who was mentioned in the 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.
  • Rosalina is always described as a princess in fanon. In canon, however, she is never referred to as royalty. She is just "Rosalina," not "Princess Rosalina" or "Queen Rosalina."
  • Ashley from WarioWare is usually interpreted as being eight due to the fact she looks and sounds like a little kid, rather than a teenager like she actually is. Urban Legend of Zelda is that she's eight in Japan but sixteen internationally, but that's not true. Her age is never referenced in Japan.
  • Look at any Luigi/Daisy fan art and Luigi will almost always be depicted a fair bit taller than Daisy. This is either a misconception or an attempt to distinguish them from Mario/Peach. Their height difference is not nearly as pronounced as that of Mario and Peach is, but Daisy is actually slightly taller than Luigi.
  • Daisy never appears in main games because she puts up too much of a fight to be kidnapped. Alternatively, she is so desperate to be in a main series game that she wants to be kidnapped.
  • Daisy is frequently depicted as being chubbier than Peach and Rosalina. It was originally a derogatory concept, however her fans began to draw her as a Big Beautiful Woman too. When Daisy is combined with Peach and Rosalina, they're made into a Big, Thin, Short Trio.
  • It was common for Rosalina to be presented as The Stoic, The Woman Wearing the Queenly Mask, or an Emotionless Girl. However, with appearances in series like Mario Kart, that's changed. She's still depicted as more regal than other characters, though.
  • Early canon from Japan, Korea, and the Americas had Peach as having a living father who is conveniently off-screen. Fans usually depict her as being orphaned as a teenager, and in canon she just has no onscreen parents.
  • The concept that everyone is an Animated Actor is a popular one, mostly due to Miyamoto likening the relationship between the characters to the trope. The characters are animated actors for Super Mario Bros. 3, but it's only confirmed for that game, and even then in a tongue-in-cheek manner, with the actors comment being a metaphor for how Mario and Bowser can be arch-enemies one game and go-kart buddies the next.
  • 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.
  • An interesting bit of Luigi fanon from the Wii era involved presenting Mr. L as his wicked inner shadow, which seems to have been born of a historical accident — Mr. L's debut game occurred within the same era as Super Smash Bros. Brawl, where Luigi was described as having an inner darkness and his Limit Break was the Mind Screw Negative Zone. This has mostly disappeared as of the Wii U era, now that Nintendo has let up on the Darker and Edgier characterization.
  • Miyamoto's interview with iJustine revealed that that Toads were initially concepted as genderless. This fact gained a whole new life in fandom, where they're considered a genderless race taking on gendered characteristics, creating a lot of confusion when it comes to Toads previously established as explicitly male and female in RPG games like The Thousand-Year Door. However, this becomes easier to swallow with the distinction between gender and biological sex according to some paradigms.
  • 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 Mario Kart 64 but was replaced with Donkey Kong; the Magikoopa who blasts Mario away from Peach's Castle in Super Mario Galaxy (a Prima trading card for SMG confirms that it was indeed Kamek out of Japan); the Magikoopa who aids Bowser in Mario & Luigi: Bowser's Inside Story (confirmed to be him in the remake's Bowser Jr.'s Journey mode); and the Magikoopa who was a boss in Yoshi's Safari. One game, Super Mario RPG, does have Kamek in it, but he was unnamed or misnamed in the English versions. Bizarrely, 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 one to tell for sure if it's Kamek is if a Yoshi's Island reference is made.
  • Pauline has lingering feelings for Mario. They're Amicable Exes in canon but fans can't help but see Pauline as still wanting Mario back, even though Mario himself has moved on. This is usually used as a joke in Die for Our Ship Peach/Mario works, but appears more innocently as well. Her cuddling Mario's gift in the intro to one of the Mario vs. Donkey Kong games could count as Ship Tease. This goes hand-in-hand with the idea that Pauline sings "Jump Up, Super Star!" from Odyssey about Mario.
  • It's near-universally accepted by the fandom that Mario is 5'1" (155cm), Luigi is 5'9" (175cm), and Peach is 6'1" (185cm). Mario's height comes from a statue described as "life-sized" by Nintendo, but it's unlikely this number actually applies to canon, since the series tends to liberally use Your Size May Vary. Consider, for example, how comically short Mario is compared to the realistically proportioned New Donkers in Odyssey. note  Luigi and Peach's heights come from estimating how tall they should be using Mario's height as the starting point. note 
    • It's worth noting that the measurements for Luigi's Balloon World in Super Mario Odyssey do indeed put Mario's height at about five feet... Which just raises more questions about the New Donkers, who by this measure are somewhere around nine to ten feet tall.
    • To explain the above issue, as well as the fact that Odyssey shows Mario to be about the same height as Toad despite normally being a head taller, the Fanon has sprung up that Mario is in his small form rather than his normal size for the duration of Odyssey.
  • Much like Mario, there is a common assumption that the Green Yoshi who stars in Yoshi's Island, where Mario is a baby, is the father of the Green Yoshi who is friends with Mario as an adult. This theory was in place long before Yoshi's Island DS heavily implied that the two Yoshis are separate individuals.
  • Why Rosalina is how she is has never been clarified. We know she was once a normal seeming human girl but somehow turned into an ageless Mystical Waif. Her odd powers, ability to float, unusual (original) voice, and the fact it's implied that she's seen the universe rebuild itself several times has led fans to the assumption that Rosalina is a Physical God and a Deity of Human Origin, despite the fatc that as a playable character she can be killed by a Goomba.
  • Toad and Toadette as brother and sister is just as common an interpretation of them as the two being lovers, because Nintendo themselves can't make up their minds about which one it is.
  • No official reason has been given for why Pauline and Mario broke up and their romance has never been given any exposure. Fans often assume they just grew apart due to differences but remained close enough so that the break-up didn't sour their friendship.
  • One of the most prominent fanons is that Mario and Peach are a couple. While they have a lot of Ship Tease and are clearly the Official Couple of the series, most games make it clear that they're not actually dating yet. This fanon also applies to Luigi and Daisy, who aren't apparently dating despite Daisy's flirty attitude.
  • Waluigi being in love with Rosalina is prominent in fan-works due to Pair the Spares and Opposites Attract.
  • Stanley from Donkey Kong 3 is Mario and Luigi's cousin.
  • Waluigi having an amazing singing voice has started to show up after Matthew Taranto (creator of Brawl in the Family and one of the major contributors to Waluigi's popularity) released some Waluigi-themed song videos.
  • The Broodals are siblings and Madame Broode is their mother.
  • The Volts from WarioWare have quite a bit:
    • 18-Volt and 9-Volt are family, usually brothers.
    • 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 Younger Than They Look.
    • Due to her skill and how big games are in the Volt household, some like to portray 5-Volt as a Let's Player, Indie Game Designer, or video game journalist as a way of supporting her family.
    • 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 WarioWare games is located in Jewelry Land from Yoshi's Safari.
  • Pauline's blonde haired design was Pauline going through a blonde phase. She has since gone back to her natural color.
  • It's commonly believed that the manual for Super Mario Bros. says the Bricks Mario breaks within the game are transformed citizens and Mario kills them when he breaks them. Whilst the manual does say citizens were turned into bricks, it specifies only the unbreakable bricks that give Power Ups such as Coins and Mushrooms are transformed people. This seems to have originated from various satirical videos and articles about Mario being evil.
  • After Peachette was revealed, fan speculation spread that Peach isn't a human but she is instead an evolved species of Toad.
  • There's a large unspecified Southern kingdom on the map for Super Mario Odyssey. Fan speculation is that it's Sarasaland.
  • 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 Younger Than They Look. She's 13-15 (or the Kong equivalent), but she hit a large growth spurt.
  • Where Peach has Toads, and Rosalina has Lumas, many fans say that Daisy's subjects are either Pionpis (being the most humanoid of the Mario Land enemies) or Crazee Dayzees (to fit her flower motif, and round out the Mushroom, Flower and Star trio).
  • Due to one manual saying that Waluigi has friends outside of Wario and that he doesn't show up outside of sports games because he dislikes adventures, many have theorized that Waluigi is actually a fairly mundane guy who's only acting crazy when he's around Mario and his friends. Some have theorized that his name may not actually be "Waluigi" and that everyone just calls him that way because of his resemblance to Luigi and taking the role of Luigi's rival.
    • Some go further than this and theorize that Waluigi's friends are the random new human characters from the Mario Golf series; largely because those games covers state that Mario plays golf with his friends. Some have taken this as Mario accepting them as his friends, since they're friends of Waluigi.
  • Mario is sometimes characterized as being able to use the Backwards Long Jump to reach ludicrous speeds or even teleport in-universe.

How well does it match the trope?
