* InvisibleParents: With the exception of Boopkins[[labelnote:*]] (whose father is a recurring side character)[[/labelnote]], Saiko[[labelnote:*]] (who doesn't have parents due to being a video game character brought to life)[[/labelnote]], and Melony[[labelnote:*]] (who doesn't have parents due to being a transmogrified watermelon)[[/labelnote]], very little is known about the gang's parents (or family in general), with them mentioned ''very'' infrequently or, in some cases, never at all. In the case of the Mario characters, this carries over from [[Franchise/SuperMarioBros their home franchise]].

[[caption-width-right:350:Prepare to lose IQ when you're with the crew![[note]]From left to right: [[ScoutOut Shroomy]], [[CuteAndPsycho Saiko]] (before her redesign), [[GamerChick Tari]] (before her redesign), [[SleepyHead Melony]], [[TheCutie Fishy Boopkins]] (before his redesign), [[AttentionWhore Bob]] (before his redesign), [[ActionGirl Meggy]], [[NervousWreck Luigi]], [[AdaptationalDumbass Mario]], and [[AuthorAvatar SMG4]] ([[OverlyLongGag before his redesign]]). Not pictured: [[TheLancer Bowser]], [[CloudCuckoolander Steve]], [[AdaptationalJerkass Toad]], [[HairTriggerTemper Princess Peach]], [[NiceGuy Axol]], and [[PsychopathicManchild Kaizo]]. [[/note]]]]

* UncertainDoom: Just like Peach, he was last seen in the hallway of the castle after being defeated [[spoiler:before it sinks into the ground for good. While Peach is shown building a shuttle to escape the demonic maw her castle is now in as of "The Stupid Mario Movie", Toad is nowhere to be found]].

* OnlySaneWoman: In "Stupid Mario [=3D=] World" and some of her other earlier appearances. [[spoiler:This might even be an {{exaggerat|edTrope}}ion; it's implied in [="SMG4's=] Origins" that she was the only one unaffected by [=SMG4's=] appearance, although she has clearly lost a bit of her sanity from dealing with everyone's antics]].

* SanitySlippage: [[spoiler:Unlike everybody else in the series bar the SMGs, she was the only one not to be affected by [=SMG4=]'s arrival. However, after years of dealing with Mario, this fact has been diminished as she is now stuck in a state of near-permanent rage and exasperation with everybody's antics.]]

* AbusiveDad: Considering his father's first actions at his birth were voicing how ugly and horrifying he was, immediately attempting to ''kill'' him on the spot to "prevent him from laying eggs", and finally callously throwing him out the window, leaving him to grow up without any semblance of parental love, it's easy to explain why Mario is the way he is.
** Averted in later episodes [[{{Retcon}} where it's heavily implied]] Creator/ShigeruMiyamoto himself is Mario's dad. Miyamoto clearly cares about Mario but is too much of a CloudCuckoolander to be of any real help.
* {{Acrofatic}}: Zigzagged. Mario usually has a hard time physically exerting himself, but he has a surprisingly high level of agility when he has a clear goal in mind.
* AdaptationalJerkass: In this series, Mario is portrayed as a selfish, amoral JerkAss obsessed with [[TrademarkFavoriteFood spaghetti]], a stark contrast to his more traditionally heroic depiction in Nintendo's games. [=SMG4=] admitted in a 2015 [=QnA=] that the reason behind this is because he thought the generic hero character would be boring. Increasingly Subverted since 2016, while he's still largely amoral and selfish, he has largely [[TookALevelInKindness taken a level in kindness]] and does genuinely care about his friends. Subverted further in "[=SMG4=]’s Origins", where it’s revealed [[spoiler:he was like his game counterpart before the arrival of [=SMG4=].]]
* AdaptationalDumbass: '''This point cannot be emphasized enough.''' With the way he is, one has to wonder how he even made it to adulthood. [[spoiler:"[=SMG4's=] Origins" reveals he wasn't always dumb.]]
* AesopAmnesia: He gets this a lot in the series, and it gets ''really'' bad at a few points. One moment he could be mourning the presumed loss of his friends and a few episodes later he might be willing to kill them all.
* AffectionateNickname: "Red", courtesy of Meggy.
* AmbiguouslyBi: He was in a relationship with Peach during the earlier episodes, but there were some male characters he admitted he would "Smash" in "Smash or Pass". Of course, his one true [[TrademarkFavouriteFood love]] points him in a direction other than gender.
* AnimationBump: Since [=TheInvertedShadow=] joined Glitch Productions, Mario's animation has become more smooth and flowing in comparison to his ragdoll movements in other videos, a good example of this being in the ''Mario Does Stuff'' sub-series.
* AntiHero: Has shades of ClassicalAntiHero with his idiocy and generally being a loser at life, but also has bits of the modern variety with him being a [[JerkAss total prick]] and actually being the ''cause'' of the situations the main cast get involved with. However, he slowly begins shedding this with a more GoodIsNotNice disposition.
* ArtShift: Frequently shifts between his ''Videogame/SuperMario64'' model (rendered in either [=SM64=] itself when using movement or in Garry's Mod when in ragdoll mode) and a Wii-era or Super Mario Odyssey Mario model depending on what's funnier for the moment. Other times he can become a sprite drawn in one of several styles.
* AttackOfThe50FootWhatever: In addition to the various times where he grew himself via power-up or magic spell, he can become this if the [=SMGs=] use their powers to transmute memes into him.
* AwesomenessByAnalysis: [[SmartBall He has a rare moment of this]] in "Stupid Mario World", when, after he and Yoshi get knocked off of Rainbow Road and sent flying towards Earth, Mario somehow manages to calculate the exact area of Bowser's bouncy castle and lands both himself and Yoshi into it perfectly.
* AxCrazy: At times. He once threatened [=SMG4=] with a knife for asking if he can have some of his spaghetti.
* BarbieDollAnatomy: Whenever Mario is naked, this trope applies.
* BarrierMaiden: [[spoiler:As the Avatar of the [=SMG4-verse=], the entire universe will be destroyed if he dies.]]
* BellyButtonless: When he's naked.

** Insulting, disrespecting or even ''saying'' that spaghetti is anything but delicious is a good way to make him come after you. Denying him of it is even worse.
** Don't say ''WesternAnimation/DoraTheExplorer'' is stupid and boring. Otherwise, he'll open up a premium can of ass whooping on you.
** Don't hurt his brother ''or'' his friends, ''especially'' Meggy. "Mario and the T-Pose Virus", for example, gives us a ''massive'' one in the form of Bob leaving his brother Luigi to die. Mario goes straight into TranquilFury mode before throwing Bob off Peach's Castle without a second thought when this one was pressed, and [[spoiler:he punches Wario and is ready to further fight him for electrocuting and then threatening Luigi]].
** ''Mario Does Things'' establishes that ''VideoGame/AmongUs'' is one for him. In the fifth video, he threatens to eat Frankie’s limbs [[DisproportionateRetribution because he posted an Among Us meme]].
* BewareTheSillyOnes: He's a lazy, unintelligent, spaghetti-obsessed idiot… but when spaghetti is insulted or his friends are harmed, ''steer clear''.
* BigBrotherInstinct:
** He has his moments toward Luigi. Most notably in "Mario and the T-Pose Virus". When [[DirtyCoward Bob]] obstructs the pathway to the roof, leading to Luigi becoming a T-Pose Zombie, Mario is ''furious'' and throws Bob off of the roof without hesitation.
** He also has this towards Meggy to an almost heartwarming degree. [[spoiler:This is best shown in the Anime Arc on two occasions. First in "Meggy's Bootcamp" when he comforts a crying Meggy by offering her ''his'' spaghetti and assuring her that his friends will be with her when she's down; and then in "Final Hours" when he digs through the rubble and remains of the destroyed Ink-Zuccer 3000 trying to rescue her – he's completely oblivious to all the chaos erupting around him and clearly would have kept digging had he not been ''physically dragged away'' before the island exploded.]]
* BigGood: Ultimately shares the role with [=SMG4=], being one of the main protagonists of pretty much every season up until Season 9, when Meggy became the tritagonist.
* BlackSheep: In "The Grand Mario Hotel", he's revealed to be this among all the Marios in TheMultiverse. For [[DoomMagnet good reasons]].
* BlowYouAway: Gains these powers in "Final Fantasy Mario".
* BreathWeapon: After swallowing the Old Man's KamehameHadoken in "Mario the Olympian", he shoots it back out as a flamethrower, [[CruelAndUnusualDeath killing both the Old Man and Frankie simultaneously]].
* BrainwashedAndCrazy: In WOTFI 2022, Lawyer Kong brainwashes him [[spoiler:and all other Nintendo characters into fighting the [=SMG4=]-original characters in a series of challenges. He thankfully gets returned to normal just in time for the rap battle.]]
* ButtMonkey: Especially after 2021, Mario has been seen as the subject of misfortune whether or not it was his fault. Prior to this, he wasn't this as often as the likes of Luigi, Toad, or Fishy Boopkins, but he still found himself in many undesirable situations that didn't always end with him escaping unscathed (and even then, it requires a lot of effort to do so).
* TheCaligula: If Mario gets a position of power, expect him to be fair and just at first, then ultimately become a tyrannical dictator. In "The Spaghettipocalypse" Luigi even states that Mario ruling the world is worse than him getting hurt.
* CatchPhrase: "Mama-f***er!".
* CannotTellFictionFromReality: A running gag in the ''Mario Does Things'' sub-series is Mario watching a meme or game clip of a character doing something he dislikes and then taking out his rage on their real counterpart. A good example is when he saw gameplay of Rosalina drawing an ''Among Us'' crewmate and in his rage flew into space to eliminate her, all while Rosalina's eating ice cream unaware. There are, however, a [[PlayedWith few incidents]] where the memes ''are'' directly connected to reality.
* CharacterDevelopment: Starting from [[CerebusSyndrome the Waluigi Arc]], Mario has become less of a jerk to those around him, most notably Luigi and Meggy. Though his JerkAss tendencies still surface every now and then.
* CharacterizationMarchesOn: His romantic interest in Princess Peach diminished over the years, likely having become utterly fed up from having to rescue her countless times without getting much in return, in addition to her demanding and patronizing treatment of him. Mario refuses to help her make money for the Mushroom Kingdom in "Mario's Spageti Delivary" and even gets the cops to attack her in "The Visitor". By 2018, he is more or less indifferent to her.
** He still chose to "Smash" her in "Smash or Pass"… but only after putting a paper bag over her head.
* CharacterTic: He has a tendency to go cock-eyed when confused, [[TheDitz which is basically always]].
* TheChewToy: Especially in later episodes, where he gets smacked and pushed around a ''lot'' more than before, often getting into trouble even when he isn't the conflict's instigator.
* ChildishOlderSibling: Like in canon, he's Luigi's older brother, yet he's a {{Manchild}} of the highest order.
* ChubbyChaser: If "Mario Plays: Smash Or Pass" is any indication, he has a preference for people as fat as he is.
* {{Cloudcuckoolander}}: His default state of mind.
* ComedicSociopath: Mario's worst actions are played for laughs.
* ComicalOverreacting: Has a tendency to go ''[[AxCrazy apeshit crazy]]'' at the most minor offenses.
* CrouchingMoronHiddenBadass: With his LethallyStupid actions and extreme idiocy, you'd think he couldn't handle himself in a fight… and you'd be wrong, as Mario proves that when he actually uses his wits (and his own stupidity when ''that'' fails), he can overcome pretty much anything thrown at him. "A Totally Normal [=SMG4=] Episode" and "Mario's Mask of Madness" are excellent examples of this.
* CuttingTheKnot: While playing ''Dungeons & Dragons'', Mario defeats the FinalBoss by punching [=SMG4=] (The Dungeon Keeper) in real life.
* DeathIsCheap: As expected with a classic video game character, he always respawns. It takes an out-of-universe EldritchAbomination to ''genuinely'' kill him.
* DecompositeCharacter: In some episodes, he and [[VideoGame/DrMario his doctor counterpart]] are separate characters.
* DependingOnTheWriter: Became this as more staff came onboard and Luke's/[=SMG4's=] focus shifted. While Mario is generally depicted as TheDitz, he can sometimes be a [[BunnyEarsLawyer somewhat levelheaded leader who can make good decisions]] or a [[DirtyCoward cowardly]] {{Manchild}}.
** 2022 was the most extreme case of this yet, with him flip-flopping between being a [[TooDumbToLive complete idiot who can barely function]] and the [[OnlySaneMan most relatively well-adjusted character]] ''almost every episode''.
* DirtyCoward: Will often shift the blame to his friends to get out of trouble, leaving them to suffer the consequences. Although he's not as bad with this as Bob.
* DisneyDeath: In the 10th anniversary special, Zero tortures him via MindRape, and after Zero's defeat, he seems to have died from it, but then his left arm turns back to normal and he wakes up asking for [[TrademarkFavoriteFood spaghetti]].
* DoesNotLikeSpam: Mario will not touch vegetables, even if he's teetering on the brink of death from starvation (remember, tomato is a fruit). Once when he's forced on a diet, he eats broccoli… and his body rejects it.
* DoomMagnet: Pretty much everywhere Mario goes, destruction and chaos soon follow.
* DopeSlap: He's often on the receiving end of this, courtesy of his more-sane friends like [=SMG4=] or Meggy. Even Luigi is not above this.
* DrivenToSuicide: He is not immune to this, especially in the ''Mario Does Things'' series.
** While his constant deaths in ''Mario Does Things'' are PlayedForLaughs, his mental breakdown during the Lawsuit Arc where he repeatedly jumps off the Smash field and drives his kart into a wall are ''not''.
* DrunkWithPower: When someone as impulsive and unrestrained as Mario gets any measure of power, no matter how small, expect tyranny and apocalyptic disasters to follow.
* TheDitz: Long story short, he's a pain to everyone in the castle because of his extreme levels of stupidity.
* DumbassHasAPoint: This version of Mario is an absolute idiot, no denying that, but he does make some good arguments every now and then.
** After he and Toad destroy all the milk Luigi was carrying in "Mario Goes To The Fridge to Get A Glass of Milk", he simply suggests for Luigi to go back to the factory and get some more. Luigi protests but Toad actually agrees it's a not a bad idea – as an employee, nobody would be suspicious of Luigi walking in there and taking up crates to deliver since that's his actual job.
** He objects when [=SMG4=] refuses to let him help their team in "Mario's Hell Kitchen", and notes that it's unfair that he's being left out. While Mario is indeed an awful cook, he is right that it's a little unfair to single him out for it when the rest of the team consists of people who are equally bad (Bob, Boopkins), if not even worse than him at cooking (Meggy).
** When a recently human-turned Meggy thinks she can mop the floors easier as an Inkling in "Mario Does the Chores", Mario correctly imagines that she would be wrong. Inklings are creatures made from ink, and the water would dissolve her if she didn't have a RespawnPoint on standby. Plus, no longer being weak to water is an interesting perk to being human.
** In "The Day [=SMG4=] Posted Cringe", [=SMG3=] blackmails various Youtubers into helping him by threatening to post cringe videos on their accounts, which [=SMG4=] decrees as [[SeriousBusiness the most vile thing ever done]]. Mario retorts by asking about Francis's [[spoiler:genocidal plans for Inkopolis]]. Sure, [=SMG4=] brushes him off and it's treated as a joke, but Mario asking him if what [=SMG3=] did was worse than what Francis did is basically implying that [[SkewedPriorities he should get his priorities straight when it comes to recognizing true evil.]]
** In "If Mario Was In… Anime," when Axol loses his title as the world's best anime artist, Mario quickly realizes, and points out, that it's because ever since his Inkweaver broke, Axol hasn't really drawn any manga or anime and just spends most of his time fawning over Melony. Axol acknowledges this, and it gives him the incentive to repair Inkweaver.
* DumbassNoMore: In "Mario Can't Play With You Anymore", Mario is forcibly reverted back to his canon personality (jolly, heroic, etc.), removing his stupidity. This isn't a good thing as it also causes him to forget [=SMG4=] and all his non-Nintendo friends. [[spoiler:He's successfully re-corrupted after being shown several memes.]]
* EpicFail: When cooking. Or most simple tasks for that matter. But when it comes to true problems…
* EveryoneHasStandards:
** Even ''Mario'' can't stand Frankie's stupidity.
** His reaction to [=SMG4=] stupidly bankrupting himself by buying 1 million rocks in "The Mario Hustle"?
--->'''Mario''': "Mario think you a dumbass motherf*cker."
** He is horrified when he finds out what happened to [[spoiler:Spudnick]].
** Several life-hacks shown in "Mario tries Life Hacks" have Mario racking his brain at how stupid they are.
** Mario makes some weird decisions in "Mario Plays: Smash or Pass", including wanting to smash himself, but he passes with prejudice on [[BestialityIsDepraved the Kongs]], the Koopalings and Bowser Jr, and is downright horrified to see [[PaedoHunt Baby Mario]] on the list.
** "Mario Googles Himself" has Mario detesting anything depicting incest between him and Luigi.
--->''(Mario sees himself and Luigi kissing)'' "...Well, if that's the case, [[DrivenToSuicide gun]]!" ''(A hand reaches on screen and gives him one)'' "Well, thank you very much-" ''*bang*''
* ExpressiveHair: His moustache either grows or shrinks to reflect whatever's on his mind.
* FailureIsTheOnlyOption: Whenever he cooks.
* {{Fartillery}}: Often. In "War of the Fat Italians 2013", one fart was enough to ''fill up the entire scene with gas''.
* {{Flanderization}}: Mario's {{Manchild}} traits were ramped up to the nth degree in the second half of 2022, making him an even bigger manchild than he ever was before. Some prime examples are "How To Train You Mario" and "All I Want For Christmas Is Mario To FREAKIN BEHAVE". This has thnakfully been undone ([[Recap/SMG4MarioBreaksTheMcDonaldsIceCreamMachine for the most part]]) in 2023. There's also "If Mario Was The Last Man On Earth", which had him destroy his friends' pizza, leading them ''and the rest of the kingdom'' to banish him from their activities.
* FoolishSiblingResponsibleSibling: Mario is the Foolish Sibling to Luigi's Responsible Sibling.
* FeedItABomb: Mario inhales and swallows a [[Franchise/{{Splatoon}} Splat Bomb]] in "If Mario Was In... Splatoon", causing [[YourHeadASplode his head to self-destruct]].
* FishEyes: Sometimes it gets to the point where he spends entire episodes like this.
* FreakyFridayFlip:
** With [=SMG4=] in "The Switcherooveralls" and "The Swap".
** With Steve in "Mineswap", causing him to become a ''VideoGame/{{Minecraft}}'' skin and Steve to become a ''VideoGame/SuperMario64'' PaletteSwap.
* TheFriendNobodyLikes: Throughout most of the series, Mario was a senseless nuisance who caused everyone around him grief, even getting kicked out in "Mario Joins the Circus" because everyone was so fed up with him. A combination of Mario mellowing out and hanging around a newer cast of characters starting in 2016 have since thoroughly lessened this status for him, but he can still be a handful at times. "If Mario Was The Last Man On Earth" in particular has them [[spoiler:leave Mario out of the making of a record-breaking pizza after he ruined their previous attempt - leading him to accidentally wreck it again after [[GoMadFromTheIsolation going insane]].]]
* FunnyBackgroundEvent: Often when the focus is on another character, you can count on Mario to be doing something weird in the background.
* GagNose: Extending his nose became one of his powers by 2021.
* GeniusDitz: Started to lean into this beginning in 2017, especially during story arcs.
* GiveMeBackMyWallet: With Yoshi in "Wallets and Dinosaurs".
* GoMadFromTheIsolation: Mario cannot handle being alone, and it's driven him coo-coo-crazy at least twice.
** In the 2019 Christmas Special, he misses the bus to Florida because he's asleep in [=SMG4's=] room and locked the door so no one can wake him. Once he realizes his friends left without him, he spends the rest of the day building lookalikes of the main cast from items in the castle… in the process also creating future major character Melony.
** In "If Mario Was the Last Man On Earth", his friends dump him after he ruins their first attempt at breaking a world record. Within not very long, he's completely lost it; he has a conversation with three mannequins he dresses as [=SMG4=], Luigi, and Meggy (even ''he'' realizes this is silly); and eventually hallucinates Hobo-Mario who he mistakes for god.
* GodzillaThreshold:
** In "The Grand Mario Hotel", the [[TheMultiverse other Marios]] end up seeing him as so LethallyStupid that they decide to team up to kill him. To put things in perspective – one of them is Bootleg Mario from "THE BOOTLEG DIMENSION", someone who once caused a RealityBleed SuicidalCosmicTemperTantrum that Mario had to stop.
** In "Smart Mario", Mario's latest bout of idiocy is such that everyone in the castle, even Luigi and Meggy, decide to force him to become smart through one of E. Gadd's inventions. This despite how they (save E. Gadd) see it as a last resort. [[StatusQuoIsGod It doesn't last.]]
* {{Greed}}: Over spaghetti and (sometimes) coins.
* GuileHero: [[NotMakingThisUpDisclaimer Yes, really.]] He often shows this when battling, using his environment or [[IgnoranceIsBliss blissful stupidity]] to his advantage.
* HiddenDepths: Mario can do ''some'' things well…
** "Freddy's Spaghettiria Security Breach" shows that Mario's a natural at making pizza despite normally being a LethalChef. He also shows this in "Mario Destroys the Environment" despite not being able to make an edible pizza the week before; his pizza is so good a group of sentient trees ''willingly'' sacrifices itself to create a pizza stand for him.
** He's also good at building things when he feels like it. For example, assembling beds for Melony twice when Axol couldn't. He can also build {{humongous mecha}}s to terrorize his friends in challenges.
* HypocriticalHumor: In "If Mario was [[VideoGame/AmongUs AMONG US]]" he said that red is a stupid color despite the fact that he wears red.
* ICallItVera:
** In "The Plumber Problem", he put a sombrero on a [[VideoGame/MarioKart banana peel]] and named it "Eduardo".
** He calls his spaghetti "Sarah".
** He names a rock "Jason" in "Mario Gets Stuck On An Island".
* IdiotHero: He's one of the two overall [[BigGood Big Goods]] of the series, but is clearly very immature, dimwitted, and often reckless. [[spoiler: [[WhamEpisode SMG4's Origins]] reveals that he used to be like his video game counterpart before SMG4's Guardian Pod landed in the kingdom and turned him into the spaghetti-obsessed dumbass he is today.]]
* TheImmune: Mario frequently finds himself immune to the episode's big problem, leaving him as the only one able to save the day.
** Mario takes up the role of Frodo in ''Lord of the Memes'' as he's immune to the corrupting effects of the ultimate meme, being too dumb to figure out why it's so funny.
** The Mario Mask has no effect on him in "Mario's Mask of Madness" because, well, he's already Mario.
** He's immune to the titular ''Clown Fever'' because he ''always'' makes a fool of himself.
* InnocentBlueEyes: Heavily inverted. He has blue eyes like in canon but is a {{Jerkass}} and InsufferableImbecile.
* {{Jerkass}}: Before he TookALevelInKindness, Mario was a profoundly careless, destructive, self-centered glutton who lacked a moral compass; and despite clearly caring for his friends, he let his love of food constantly overshadow his relationships. He still shows signs of being a DirtyCoward from time to time.
* JerkWithAHeartOfGold: Nowadays, while he may occasionally be a [[ItsAllAboutMe selfish]], [[{{Greed}} greedy]] {{Jerkass}}, he's shown multiple times to care for his friends in his own way.
* TheyKilledKennyAgain: Despite the show's CerebusSyndrome, Mario is still prone to this even though it's less frequent than in pre-2017 videos. Luke/[=SMG4=] passes this off as RuleOfFunny, but given Mario's [[BarrierMaiden true nature]], there's probably a good reason for it.
* KickTheDog: To Luigi throughout ''all'' of "Mario for Hire", [[LaserGuidedKarma but it bites him in the end]].
* LackOfEmpathy: There are times where Mario only cares about what he wants, though it is mostly due to his idiocy. There are also times where he suggests ViolenceIsTheOnlyOption, even when people suggest a different way.
* LaserGuidedKarma: He will rarely if ever escape karma's grasp.
* LawfulStupidChaoticStupid: Make no mistake. He may look like an idiot and talk like an idiot but don't let that fool you… he really is an idiot. However, his idiocy can be for different causes DependingOnTheWriter
* LethalChef: It has been shown that Mario cannot cook, and any attempt at cooking solo will [[FailureIsTheOnlyOption always fail]]. Unless, we are also shown, it's pizza…
* LethallyStupid: When he isn't being a {{Jerkass}}, he is causing destruction through his own [[TheDitz stupidity]].
* LikeBrotherAndSister: To Meggy, said almost word-for-word by Meggy during one of her livestreams.
* MajorInjuryUnderreaction: Mario got more and more used to [[TheChewToy constantly being abused]] as the series went on, and now tends to react to [[NighInvulnerable normally-lethal injures]] with mere annoyance. "Mario Does Literally Anything For Views" demonstrates this pretty well with the "Mystery Buttons" segment, where he's more hurt by insults than he is by ColdBloodedTorture.
* ManChild: Despite being an adult, Mario is perfectly willing to play in toy stores, lay traps for Santa Claus, and do all sorts of insane antics without a second thought.
* MasterOfDisguise: Or rather the master of ''fail'' disguise, as shown in "Master of Fail Disguises". [[LatexPerfection The actual physical disguises he uses are accurate]], but he's [[PerfectDisguiseTerribleActing bad at imitating other characters' mannerisms.]]
* MeatOVision: In "Spaghettipocalypse", a delirious Mario starts seeing everyone as spaghetti. He proceeds to try to eat (and make love with, as he would with the dish) everybody.
* MindRape: Poor Mario had this happen to him by Zero in the 10th anniversary special, Zero made Mario see memories of Zero's birth and how he was defeated before.
** On a less serious note, watching several cringe Nintendo memes in a row does this to him.
* MoodKiller: Tends to be this in genuinely emotional situations.
* MoralityChain:[[invoked]] He has one in Meggy Spletzer. After meeting her in 2017, he began showing more compassion to the cast in general and Luigi in particular. It's thanks to her that his actions rarely cross the MoralEventHorizon. She's basically the only person he listens to, so sometimes it's her job to tell him ''why'' what he does upsets people (e.g. the Christmas 2022 Special when he indirectly hurt Melony's pet axolotl). [[spoiler:This shines especially in the Anime Arc, where he offers Meggy the spaghetti she had bribed him with to participate in the Splatfest training to comfort her and assure her he has her back.]]
* MoralityPet: Meggy and Tari. Ever since Mario met them, he became a little bit nicer and started to finally care about something other than himself and spaghetti.
* MyGodWhatHaveIDone: "All I Want For Christmas Is Mario To FREAKIN BEHAVE" shows a rare example of him genuinely feeling guilty about how his carelessness and stupidity hurt people; when Meggy points out how much Axol Junior (who got injured as a result of Mario trying to sneak some food) means to Melony, he becomes genuinely apologetic, and spends the rest of the video trying to make up for his actions.
* NakedPeopleAreFunny: Has gone naked frequently. Exaggerated in some videos, such as "Hunt for the Hero's Clothes" and "Mario Swag".
* NiceJobBreakingItHero: He's frequently the reason things go wrong in most videos. For example, he shows Cap'n Lardbutt his "pirate booty" in "The Pirate Plumbers", [[spoiler:only to unexpectedly unleash the squid monster]].
* NiceMeanAndInBetween: Is the "Mean" part of a trio with Luigi and [=SMG4=], being an immature, selfish, and destructive IdiotHero who is a JerkWithAHeartOfGold at best.
* NighInvulnerability: Mario has survived nearly everything that has been thrown at him whilst being barely fazed, with only an EldritchAbomination being able to even get close to killing him. [[spoiler:It's likely a side effect of being the universe's BarrierMaiden.]]
* NobodyPoops: Very averted in "100 Ways for Mario to Die (The Right Way)", which lists his 20th death (#81) as "crapping on the rug". Needless to say, Princess Peach [[DeathGlare was]] not [[UnstoppableRage amused]].
* NoMeansYes: If this trope occurs involving him, it can usually lead from a small question to the main plot elements, such as from telling [=SMG4=] if he wants to show his swag to the public to actually showing his swag in "Mario Swag", from asking Toad if he got his camera ready right to him and [=SMG4=] doing "the awesome war" in "War of the Fat Italians 2013", and from telling Luigi if he can have a spaghetti machine to go to a casino with Luigi in "Casino, Cards and Chaos".
* ObfuscatingStupidity: Meggy said in a Q&A session that she believes Mario is a lot smarter than he pretends to be. We see this during {{story arc}}s when [[LetsGetDangerous things get serious]], and even during some regular episodes where, for example, he proves to be surprisingly good at building stuff ("The Bed" and "Mario Alone").
* OffWithHisHead: Happens occasionally in the main series and ''a lot'' in ''Mario Does Things''.
* OlderThanHeLooks: Zig-zagged. Early episode "the (TOTALLY ACCURATE) documentary of mario" claimed Mario was born in 1928, but he looks his canon age of 24-26. Modern episodes take no real position on his age.
* OnlySaneMan: Yes, he can be this, thanks to some occasional strokes of intelligence. It's rare, but if he's not causing or indulging in chaos, he'll usually be critical of it.
* OOCIsSeriousBusiness:
** When ''Mario'' is angered by someone else's stupidity, you know they're really dumb.
** When Mario is legitimately scared, things get [[CerebusSyndrome serious]]... [[PlayedWith sometimes]], because he's just as likely to be scared of serial killers, eldritch abominations, and [[spoiler:Zero]] as he is to be scared of a lack of spaghetti.
** Mario's TranquilFury is a surefire sign that someone's fucked up.
** Normally violently protective of his spaghetti, [[spoiler:in "Meggy's Bootcamp, Mario ''willingly'' gives it to Meggy because he's so concerned about her well-being after she has a breakdown about how horribly she treated him and the others during Splatfest training.]]
** Even the world's dumbest man [[DrivenToSuicide can't handle]] learning that his world is a simulation.
** During the ''Revelations'' movie, when Niles possessing Melony tries to re-merge with [=SMG0=], Mario kicks him and has this to say:
--->'''Mario''': "Mario's not the smartest guy in the room. But Mario knows enough to say that you need to shuttup and let Melony go."
** PlayedForLaughs in "Mario Goes To The Zoo", where he picks up the SanityBall and becomes the OnlySaneMan, emphasizing how bonkers everybody else went.
** Mario usually doesn't care how much his antics hurt others, but when he accidentally gets Axol Junior hurt in "All I Want For Christmas Is Mario To FREAKIN BEHAVE" and upsets Melony in the process (especially given [[spoiler:what happened to AJ's namesake]]), even he realizes he's gone too far, though Meggy has to [[WhatTheHellHero spell it out to him first]].
* ParentalAbandonment: His parents threw him on the side of the road when he was born, on account of him being such a hideous baby, his father tried to kill him "before he laid eggs". For all we know, [[FreudianExcuse it's pretty much why Mario is the way he is]]. This may be {{retcon}}ned though as "[=MAR10=] Day" shows he's the product of Miyamoto-san eating some bad spaghetti and puking him out.
* PalsWithJesus: He's pals with Slenderman, Siren Head, and Huggy Wuggy among others. Averted with Jesus himself, who appears from time to time in this series but doesn't like Mario much.
* PetTheDog:
** He warned Luigi of the Chain Chomp that was chasing him and [=SMG4=] in "Who Let the Chomps Out?", compared to earlier videos where he would likely just throw Luigi in to distract the Chomp.
** In "Mario and the retarded spaghetti factory", after escaping from his prison cell, Mario proceeds to rescue a woman in the cell next to him, even though he had no reason to... ([[KickTheDog at least until he shot the woman for reminding him of Peach]]).
** Mario says it best in "Meet the Mario". As long as his needs are met, Mario would try to act nicer. The thing is [[WellIntentionedExtremist he's]] very dumb even then. And most often, his needs are far from being met.
** In "Meggy's Bootcamp", [[spoiler:he genuinely comforts Meggy as she's [[HeroicBSOD having an emotional breakdown]] over what a {{Jerkass}} she had been, [[AwLookTheyReallyDoLoveEachOther even giving her the spaghetti she had bribed him with earlier]]]].
** In "If Mario Was In… Nickelodeon", During the chaos he causes with Cosmo's wand, he apparently wished for Melony to have a pet axolotl. This may be he wanted to make Melony feel better after [[spoiler:Axol's death]] (the episode aired shortly after the end of the Genesis Arc). Unfortunately, this was semi-{{retcon}}ned in "All I Want For Christmas Is Mario To FREAKIN BEHAVE".
** Perhaps the biggest example so far was from the 2021 Christmas Special. As Santa's replacement, even though he was forced to, he does his best to make everyone happy, and most of his gifts are actually well received. All of his efforts were repaid in the end when everyone comes to celebrate Christmas with him.
* PlotArmor: Justified. [[spoiler:He's the Avatar of Nintendo World ([=SMG4=] is its guardian), so if he dies, ''the rest of the universe dies with him''. That gives the universe itself a motivation to sweep [[TheManyDeathsOfYou The Many Deaths Of Mario]] under the rug, though an EldritchAbomination like Zero could kill him off for real.]] It's for this reason that he's classified as a B-tier.
* PsychopathicManchild: Is just as crazy as he is immature.
* RageBreakingPoint: Has a massive one in "[=SMG4=] Christmas 2018", where he goes ''apeshit'' on Bob. Though Bob deserved it after all he did, [[OOCIsSeriousBusiness it's out of character for Mario]].
* RealityWarper: He's able to rip open portals to/from the void with his bare hands, dimension-hop through backwards-long-jumping, break physics in general, handle black holes, summon Satan (sometimes by accident), phase through walls and doors, and create a new recurring character (Melony). No one else ever notices.
* TheReasonYouSuckSpeech: He gets these often. Usually it is well deserved but they rarely, if ever, affect him.
-->'''[=SMG4=]''': "MARIO, YOU'RE RETARD WITH A MENTAL DISORDER, OK?!"
-->'''Peach''': "First, you almost destroy the world, and then you don't take out the trash properly! Why do you have to be so useless and difficult?!"
** It's been shown that if ''Meggy'' gives him one, it's more likely to get through to him…
--->'''Meggy:''' "Dude…! Axol Junior means the world to her! She's been caring for him ever since… well… you know. And you really injured him, Mario!"\\
'''Mario:''' "WAHHHHH!! MARIO'S SORRYYYYYY!! Mario will go say sorry right now!"
* RedIsHeroic: He wears red overalls and his iconic red cap just like his main counterpart, but thanks to the AdaptationalJerkass and AdaptationDumbass treatment he's been given here, he's an AntiHero and a JerkWithAHeartOfGold at best, or a VillainProtagonist at his worst.
* RedIsViolent: Again, he wears red overalls and a red cap, and can sometimes be quite destructive and reckless at times if unprovoked.
* TheRival: Mario is one to basically ''every character'' in the series at some point, except ''maybe'' Luigi. How serious and/or friendly the rivalry is depends on the other character and the situation. In particular, he's [=SMG4's=] main rival in the first seven ''War of the Fat Italians'' episodes.
* SanityBall: Holds one whenever he deals with Frankie, who is EVEN DUMBER than he is.
* SkewedPriorities: The Mushroom Kingdom is going to be taken over by Shy Guys? He doesn't care. The Shy Guys are also going to destroy all the spaghetti in the Kingdom? ''Holy shit! This is serious''. He's since begun doing it for more selfless reasons, such as his friends, although it still takes prodding to get him to fully cooperate.
* SmartBall: When the situation calls for it, he will drop all forms of stupidity and get to work to solve it quickly, such as...
** Whenever he deals with the [[VideoGame/FiveNightsAtFreddys animatronics]], such as tricking the withered animatronics into attacking their toy counterparts and jumpscaring Purple Guy and the Puppet.
** Tricking [[VideoGame/{{Deltarune}} Jevil]] into flooding the arena with incredibly lethal weapons.
** Using the couple-hour window before Wario & Waluigi robbed Peach's castle (where Mario was left alone on Christmas) to set up traps.
** When Minions infested the world thanks to the release of their latest movie, he quickly tries to find ways to destroy them all and doesn't stop until he completes his task.
* SociopathicHero: At his absolute ''worst'', he can be completely intolerant to the feelings of others or even the ''cause'' of the horrid situations the main cast get involved in. This happens either because of his own stupidity or outright malicious intent. [[TookALevelInKindness He's mostly dropped this since 2016]].
* SpontaneousMustache: {{Inverted}}. Mario obviously has a moustache 99% of the time (often stretched to a comically large size), but sometimes it suddenly disappears when he's particularly shocked or disturbed.
* SuddenlyVoiced: Downplayed. He’d used voice clips from his real-life voice actor Charles Martinet for years, but starting in 2021 he began using the Uberduck.ai Mario voice for some of his lines.
** Played straight during the "War Of The Fat Italians" raps, where he gets full voiced lines.
* SyntheticVoiceActor: As of 2021, Mario started using the Uberduck.ai Mario voice for some of his lines in addition to his standard Charles Martinet voice clips.
* TheyKilledKennyAgain: He dies a lot, usually thanks to his own stupidity, but he always comes back afterwards. [[spoiler:His nature as his universe's Avatar means that permanent death will destroy the universe, though.]]
* ThirdPersonPerson: Just like in canon, he slips into this.
* TooDumbToLive: Mario dies on a frequent basis due to his stupidity. For example, he eats things that would make a nuclear waste disposal retch, his reaction to a wall of death is to ''stick his face in it'', and when he got his hands on a Death Note? He angrily killed himself '''by accident.''' Without his friends to guide him around, he would die even more often. But, as noted above, [[TheManyDeathsOfYou his many deaths]] don't stick for several reasons.
* TookALevelInDumbass:
** In "Who Let the Chomp Out", he proceeds to ''[[TooDumbToLive stand on a Chain Chomp's pedestal]]'', all in an attempt to mock [=SMG4=].
---> '''[=SMG4=]''': "[[LampshadeHanging DON'T GO FULL RETARD ON ME NOW]]!"
** This has also been slightly inverted over time, where Mario has some moments of being the relative OnlySaneMan (such as questioning if [=SMG3=] hacking into a bunch of [=YouTube=] accounts is really more evil than [[spoiler:Francis's full-on genocide]]), and he tends to solve problems through creative thinking more. Unfortunately, this has also been slowly PlayedStraight over time in terms of his maturity as well, making him [[{{Manchild}} behave more like a child]] to the point where he has to be ''babysat''.
** ''[=SMG4=] Origins'' reveals that [[spoiler:Mario used to be as smart as he is in the canon ''Super Mario'' series, and that his stupidity was caused by the flash drive that [=SMG4=] arrived in.]]
* TookALevelInJerkass: In "Mario for Hire", where his LackOfEmpathy is exaggerated and he is completely remorseless when he sics the [[VideoGame/TeamFortress2 Heavy]] on Luigi. [[LaserGuidedKarma Luigi gets back at him]] at the end though.
* TookALevelInKindness: Evident since 2018. While his stupidity can still land him (and others) into trouble, he still acts way more amicable with the people he cares about and is more willing to help those in need. It shines most especially in ''Meggy's Destiny'', where he participates in the last Splatfest with Meggy alongside Luigi and Tari and is defensive of her against the jerkish opposing team Killer Ink.
* TrademarkFavoriteFood: Spaghetti, to an absolutely ''ludicrous'' degree.
* TranquilFury: It's rare, but even he's not below slipping into this. When he does, ''get outta there!''
* TrueCompanions: With Meggy. He may not show it often, but he does respect and care for her in his own way. This extends to his brother and his other friends, too. Particularly Tari, who (as the designated female ButtMonkey of the series) is by far the most likely to join him in his crazier antics.
* UnstoppableRage: Chica and the other animatronics had to learn this the hard way. If Chica hadn't found the spaghetti on the floor and proclaimed it tasted like shit...
* UnsympatheticComedyProtagonist: Was this before, and still has his moments even today, but has been improving since 2017.
* VillainProtagonist: Of ''a lot'' of episodes, some examples being "Mario for Hire" and "Mario Gets Into [=NFTs=]". He's more of a NominalHero whenever he isn't.
* VomitIndiscretionShot: Frequently. Also parodied/subverted with him turning away from the scene. This occurred in "The Visitor" while Bowser Robot is singing, "Mushroom Wars" when the gang reacts to Dr. Robotnik's "just let your head flop back" lesson, and in "Clone o' Mario" by a recently-created Mario clone.
* VitriolicBestBuds: Mario is actually great friends with Bowser whenever they aren't fighting over Peach or something else. He also genuinely cares about the rest of the gang despite their antics. This was best shown in the "Lawsuit Arc", where he can't bear living in a world where his friends from Nintendo have been reset to their canon personalities and his non-Nintendo friends have been exiled and stops at nothing to try and save them.
* WeirdnessMagnet: For every adventure started by Mario's stupidity, there's another that he'll just stumble into. A frustrated Saiko lampshades Mario's status as one in "War on Beeg [=SMG4=]":
--> '''Saiko:''' "WHY DOES CRAP LIKE THIS ALWAYS HAPPEN WHEN I'M WITH YOU?!"\\
'''Mario:''' "[[WesternAnimation/TheSimpsons I don't know.]]"
* WeWantOurIdiotBack: "Smart Mario" has the others turning [[InsufferableImbecile Mario]] smart after putting up with his stupidity for so long. Things go well at first, but Mario proves that even though he's smarter now, he's still just as immature as when he was an idiot. In fact, he plans to get revenge on everyone for treating him as such. This makes the others realize even though Mario was stupid, he wasn't as threatening, prompting them to change him back.
* WhatTheHellHero: [=SMG4=] gives these to him often.
* YourHeadASplode:
** This is death #36 in "101 ways for mario to die (the right way!)". Mario, upon seeing Toad no longer has his Justin Bieber magazine, becomes so happy he becomes light-headed.
** Gets this after eating a live Splat Bomb in "If Mario Was In... Splatoon", thinking it was a Dorito.
** His head blows up often when watching Nintendo memes or other internet videos too stupid even for him.

!!Classic (Introduced: 2011 - 2015)

[[folder:Princess Peach]]
!!Princess Peach
->'''Voiced by:''' Samantha Kelly (voice clips), Luke ([=MarioTube=] 2)
->'''First appearance:''' "[[Recap/SMG4TheCakeIsALie The cake is a lie!]]" (2011)
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/d4017fd9_f177_40ca_a4a1_10a189f4c5de.jpeg]]
[[caption-width-right:350:[[YouHaveFailedMe "Mario]]... [[OneWingedAngel RAAAAAAAAAAAAAAAARGH!"]]]]

The ruler of the Mushroom Kingdom and the castle Mario and almost everyone else resides in. In earlier bloopers, Mario had (on occasion) tried to get her affection, but almost always failed.
----
* AntiVillain: Unlike Waluigi and Bob beforehand, she's not openly malicious or villainous. Her reason for banning anime is more of a desire to protect her kingdom (and her castle) if anything. [[spoiler:She also allows those who are fighting for the unbanning of anime to make their case and is ultimately convinced by them to let it be unbanned]].
* ArtShift:
** {{Lampshaded}} in "Castle Royale", when she becomes so happy she turns into an animated GIF.
* ArcVillainess: Became one of these with "Mario's Illegal Operation", as she made the law banning anime forever in the first place, and keeps her position for [[spoiler:half of]] the Anime Arc.
* BelligerentSexualTension: Her and Mario's relationship is, for the most part, the two driving each other completely insane. Mario sees a punching bag with her face on it and alternates between punching it and [[BreadMilkEggsSquick humping it]]. Make of that what you will. However, apparently they had sex a few times in the older eras, if Mario walking out of her bedroom naked (granted this isn't exactly unique or unusual for Mario on the daily-o) in one episode is an indication, meaning at least prior to the relationship dissolving, they did find a healthy catharsis.
* BerserkButton:

* NotQuiteDead: At the end of "IT'S GOTTA BE PERFECT", [[spoiler:she's trapped in her castle as it's being swallowed by a giant monster, with no means of escape]]. Come "The Stupid Mario Movie", [[spoiler:not only does she survive this, she's building a shuttle to escape]]. [[spoiler:By the time of '"Let's Go Visit Peach!" however, she seems to have succumbed to the madness of the demonic monster]].

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/smg4_2_5.png]]

* TookALevelInJerkass: His gradual SanitySlippage following "[=SMG4=]... Are You OK?" leads to him becoming more and more anti-social and shunning himself out from the rest of his friends and refusing to partake in their activities in favor of trying to create his perfect video. It got to the point where he even derailed a Mario Does Things video to continue working on the perfect video on Mario's computer thanks to the internet being down on his end. It reached its head during "[=MAR10=] DAY" where he goes on a mindless rampage after Wario's HostileShowTakeover during the [=Mar10=] Day party knocks out the internet router, and ends with him yelling at Mario to "'''''JUST LEAVE ME THE''''' '''''[[PrecisionFStrike F*CK]]''''' '''''ALONE!!!'''''" Any swear beyond his trademark "Goddammit!" is just outright cruel and ''extremely'' out of character. [[spoiler:The following movie, however, does imply that this had something to do with DemonicPossession from his [[NonIndicativeName Completely Regular Keyboard]].]] [[TookALevelInKindness He does get better]] [[spoiler:[[MyGodWhatHaveIDone once his actions lead to the castle being destroyed and promptly consumed by the keyboard]]]].

* BrainwashedAndCrazy:
** In WOTFI 2021, [[spoiler:[=Ax0l=] creates a corrupted duplicate of Mario known as [=Mari0=] to fight the main [=SMG4=] gang in the final battle.]]
** In WOTFI 2022, Lawyer Kong brainwashes him [[spoiler:and all other Nintendo characters into fighting the [=SMG4=]-original characters in a series of challenges. He thankfully gets returned to normal just in time for the rap battle.]]

* TrademarkFavouriteFood: Pineapple pizza, [[PineappleRuinsPizza much to everyone else’s chagrin]].

* {{Flanderization}}: Mario's {{Manchild}} traits were ramped up to the nth degree in the second half of 2022, making him an even bigger manchild than he ever was before. Some prime examples are "How To Train You Mario" and "All I Want For Christmas Is Mario To FREAKIN BEHAVE". This has thnakfully been undone ([[Recap/SMG4MarioBreaksTheMcDonaldsIceCreamMachine for the most part]]) in 2023.

* ManOnFire: A common trait among Toads in this series.

* OriginalGeneration: Whereas the other characters were established from another franchise or were multicolored Marios, all of the newcomers since Shroomy have been completely original characters. Meggy's transformation into a human would later cement her as one too. And later than that, the in-universe Nintendo's forced redesigns of [=SMG4=], Fishy Boopkins, and Bob would have them follow suit.

* ArtEvolution: Starting with "It's Gotta Be Perfect", [=SMG4=]'s redesign was updated with a new model, which was more detailed and expressive than his old one.
* TheAtoner: After his actions as a result of his insanity led to Peach's castle [[spoiler:getting swallowed by an EldritchAbomination]] in "It's Gotta Be Perfect", he resolves to make up for it by building a new and better castle.

* DemonicPossession: After he starts working on his "Perfect Video" , he starts losing his sanity, alienates himself from his friends while becoming increasingly aggressive and continues to keep saying "[[MadnessMantra It's gotta be perfect]]" and eventually writes it repeatedly on the walls of his room with a 100 hour livestream of him working showing his workspace continuing to get darker every 24 hours. When [=SMG3=] and Meggy attempt to try and snap him out of it during an announcement video however, [[spoiler:he appears to have actually been expecting them while saying "it's gotta be perfect" three times as his face becomes nightmarish the third time while strange symbols appear around him and his voice gets as deep as it did when he used the anti-meme energy in the Revelations movie]].

** While his constant deaths in ''Mario Does Things'' are PlayedForLaughs, his mental breakdown during the Lawsuit Arc where he repeatedly jumps off the Smash field or drives his kart into a wall are ''not''.

--->''(Mario sees himself and Luigi kissing)'' "...Well, if that's the case, [[DrivenToSuicide gun]]!" (''A hand reaches on screen and gives him one'') "Well, thank you very much-" ''*bang*''

* GeniusDitz: Started to lean into this in later videos, especially during story arcs.

* HiddenDepths: "Freddy's Spaghettiria Security Breach" shows that Mario's a natural at making pizza despite normally being a LethalChef.

* LethalChef: It has been shown that Mario cannot cook, and any attempt at cooking solo will [[FailureIsTheOnlyOption always fail]].

-->'''Mario''': "Mario's not the smartest guy in the room. But Mario knows enough to say that you need to shuttup and let Melony go."

* ThirdPersonPerson: Just like in canon, he occasionally slips into this.

* TheFriendNobodyLikes: He's treated as one in-universe and is the biggest example of this in the whole series. Justified, as he's obnoxious, inconsiderate, lazy, incredibly selfish and just an all-around douche - or he's a disruptive, hyperactive annoyance when he's on a sugar high.

* TheFriendNobodyLikes: Not as bad as Toad, but Bowser isn't well-liked by most of the cast. That's slowly changed throughout the years.

** Despite his constant abuse and neglect of them, Bowser is horrified to see that he has lost custody of Bowser Jr. and the Koopalings and is more than motivated to get an A in Peach's parenting class to get them back.

->'''Voiced by:''' Creator/CharlesMartinet (voice clips), Kevin Lerdwichagul ([=MarioTube 2=]), David Phillips ([=WOTFI=] rap battles,"Breaking Luigi")

Mario's younger brother and one of the two {{Deuteragonist}}s of the series, specifically the deuteragonist of the classic era. He makes smarter decisions than Mario, but he's still as cowardly as he is in the actual games, if not more so.

* HiddenDepths: Starting with "To Become A God", he started taking up meditation.

* MistakenForGay: Frequently, usually from Mario. Turns out he's actually bisexual. However, later seasons show him to lean towards the homo side more often and he is especially more open about it from 2021 onward, having put up pride colors on a few occasions, a recent example being from the ending of "We Don't Talk About Luigi" where the sign that Luigi put up on his flower shop has the gay flag.

* NewJobAsThePlotDemands: DiscussedTrope as shown in "Wild, Wild Mario", where he is stated to have at least 53 part-time jobs. He also stated this in "Detective Mario and Pikachu" and "The Corn Trip". Justified as he did it to pay for Mario's damages.
