"And was like "yeah this is crap it's going nowhere"... Boy was I wrong!"
Richard Michael Alvarez, creator of the series, on his opinion of the creation of the series

Stupid Mario Brothers or StMB is a relatively popular Nintendo fan series hosted on Richalvarez's YouTube channel. It is independently made by a group of friends who also made Youtube News and Arthur vs. The Druids vs. The Grail.

The show features a Massive Multiplayer Crossover of many Nintendo characters such as the titular Mario and Luigi, as well as a few from from other franchises. It places them in the real world, where they can do anything from playing their own game to saving the entire world.

The show officially ended on June 5, 2012 with episode 75 "The Super Mario Brothers".

It received a sequel with the Darker and Edgier The Plumber Knight Returns set decades after the events of Stupid Mario Bros, and then on November 20, 2015 another sequel titled Stupid Mario World; this series is closer to the comedic tone of Season 1, and picks up few years after the original series (well before the events of The Plumber Knight Returns). The series concluded with a second movie, Stupid Mario Brothers: Legacy, released in 2017.

Now has a recap page in construction.

This series provides examples of:

  • Accidental Misnaming: Zubashi's name is mispronounced a lot.
  • Action Girl: Mona and Daisy, even Peach briefly serves this against Nox.
  • A Good Name for a Rock Band: X and the Ys version with Johnny Mushroom and the Kingdoms.
    • Along with Wario's short lived band Tommy Fungus and the Dungeons.
  • April Fools' Day: Episode 55 was delayed for two weeks, replaced with a video PSA about smoking by Snake.
    • The same thing was repeated with Episode 68, only with a skit featuring Julian (Snake) and Austin (Brock) where Julian plays Resident Evil 4. Richard hilariously lampshaded the fact people fell for it the second time around.
  • All Just a Dream: The beginning of Episode 46.
  • Arson, Murder, and Jaywalking: In Episode 10:
    Donkey Kong: Can you guys forgive me?
    Mario: OF COURSE NOT! Did you think I would just forget about this, Pauline, and the toilet seat!
  • Artifact Title: The show started off as a nonsensical comedy with no real plot and the characters engaging in random slice-of-life activities. Once they decided to add more elaborate story arcs the show became more dramatic and less "stupid".
  • Ascended Extra: Walgina gets a bigger role in Season 3.
  • Aside Glance: After Link drank bad milk and the others said he won't be in Season Three, Ash says his fans will be pissed, but Mario says they'll get over it. Cue this trope.
    • Wario and Waluigi do a few of these in the finale.
  • Back for the Finale: Everyone except Ash, Daisy, Peach, Otacon and a handful of other characters returns for Season 5. Link in particular makes one last appearance in the final episode.
  • Back from the Dead: Almost every villain. And it's lampshaded every time. The most notable example so far is a comment made by Snake to Tommy Vercetti in Season 5:
    Snake: I'm sick and tired of people coming back from the dead for no reason! This time, I'm gonna kill you, and you're gonna ''stay'' that way!
  • Back Stab: Practically a theme.
  • Badass Biker: Wario's WarioWare costume. (He still needs a bike though)
  • Badass Normal: UPS and arguably Fed Ex. That is, when they don't use slap combat.
  • Badass Longcoat: The Darkness sports one of these, as does Liquid Snake and Blaire Vherestorm.
  • Berserk Button: If you know what's good for you, never dance in front of the Dance Instructor.
    • Be sure to never pitch a video game idea to Bob and Joe. Ash succeeds with his Pokemon idea, however.
      • The Darkness has an unfunny one when Wario tells him he's still in Mario's shadow.
      • Do not insult Ace of Base (the band that sings The Sign) in front of UPS, or ELSE.
  • Big Bad:
    • Season One: Bowser
    • Season Two: Nox Decious
    • Season Three: Wario
    • The Movie Act I: Bowser
    • The Movie Act II: The Darkness and Mr. L
    • Season Four: a Big Bad Ensemble in The Trifecta (a.k.a. Blaire, Ken and Liquid)
    • Season Five: Ganondorf's Army AND The Darkness's Army (Well until the Enemy Mine)
    • The series finale retcons Ganondorf into having been this all along.
  • Big Bad Ensemble: Season 4’s Trifecta and Season 5's two main enemies, Ganondorf's Army and The Darkness's Army
  • Big Damn Heroes: Peach saves Mario from Wario at the end of Season One.
    • DK saves Mona from Pauline in Episode 67.
  • Boom, Headshot!: How Snake kills Liquid the second time around and Pink Mist comes out.
    • Repeated in Episode 61 with Tommy Vercetti. Seriously.
  • Bond One-Liner: "Goodbye Mr. Vherestorm. It was nice meeting you" After Waluigi kills Blaire Vherestorm.
  • Booze-Based Buff: In the finale, when Captain Morgan drinks some rum to fight, it gives him effects like the Invincibility Star.
  • Boy Band: Johnny Mushroom and the Kingdoms - they even do music videos from time to time, and are often said to be better than The Jonas Brothers.
  • Bread, Eggs, Milk, Squick: Blaire's offer for Ken to join the Trifecta was a promise of $10,000 and Chun-Li's head on a stick.
  • Breaking the Fourth Wall: Happens quite often, the best known example being when Snake, Otacon, and Ash visited Richard to make him edit their entire trip to Merlin's Table. Later, when the Darkness approaches Luigi and Wario in an attempt to start an alliance, they say he will have to wait a week (the episodes are released once a week), after which the Darkness objects and says he is sick of breaking the fourth wall.
    • The example that will stay on all fan's minds is Mario's last words: "Thank you for giving me the best five years of my life."
  • Breather Episode: Episode 45 and Act 1 of The Movie.
    • Most episodes of any season before the season's respective Big Bad shows up about halfway or three fourths of the way through.
    • All but the final episode of Season 1.
    • Episode 71.
  • Brick Joke: In "The Interactive Adventure," Luigi ended up inheriting a mansion. In the first episode of Season 4 he sold it for a life supply of USB flash drives so he could never run out of memory. In Episode 53, Mario returns after he gains his memory back prompting Luigi to suggest a flash drive.
    • At the beginning of Season 4, Snake claims that he saw his brother Liquid (whom he believed to have killed in The Movie) drinking Starbucks. When it is revealed Liquid is alive we find out Blaire recruited him to the Trifecta by finding him drinking Starbucks.
  • Broke Episode: "The Interactive Adventure." Mario was too lazy to pay rent and the landlord didn't accept gold coins as currency.
  • Brought Down to Normal: Mario, Luigi, Wario, and Ness suffer from this from the end of Operation Blind Storm to the latter half of Season Four as part of The Darkness' Evil Plan.
  • Buffy Speak: "I believe it was my foot that had the stepping on!"
    • "That was suck!"
  • Cain and Abel: Merlin and Nox Decious.
  • The Cake Is a Lie: Or 'pizza' in this case!
  • Call-Back: Plenty, the most recent being the first episode of Season 4 (as well as Act I) recreating the opening to Season 1.
  • The Cameo: The Random Bum from Youtube News pops up as a member of the Mafia in Season Four. Only to be killed by Max Payne.
  • Catchphrase:
    • Luigi: "What are we going to do now Mario?"
    • Ash: "I Gotta Catch 'Em All"
    • UPS: "What can brown do for you?"
  • Cerebus Syndrome: The very first season was largely centered on the Mario Bros. goofing off until Episode 15, after which they became much more serious while alternating between their serious and goofy selves: in Season Four, every character is a clever mix of both their serious and goofy selves, or as Mario puts it in Episode 57, "seriously funny."
  • Character Blog: Two, by Kamek and Mario.
  • Chekhov's Skill: UPS's first and later appearances show him singing I Saw the Sign. Luigi eventually hires him to replace Mario as lead singer for JMK in Season 2
  • The Chosen One: or perhaps The Chosen Two: Mario and Wario
  • Chuck Cunningham Syndrome: Ash, Peach, Daisy, Otacon and several others were forgotten after their appearances in the Move and Operation: Blind Storm. According to the Subscribe Voice, Ash is living back in Kanto and Episode 75 suggests Peach is back in the Mushroom Kingdom waiting for the Mario Brothers. The rest still don't have an explanation for their absences (Something which the Subscribe Voice lampshaded).
  • Christmas Special: In which UPS intern Francis makes a mistake, resulting in the Mario Brothers believing that the other brother did not get them a Christmas present.
  • The Comically Serious: Snake. Subverted in The Interactive Adventure when he tries to be funny but fails and is beaten by Wario. But, by the end, he gets the Super Mario Bros. laughing with a banana joke—that is, until Wario beats it with Two Bananas.
  • Composite Character: In-universe example: Merlin, the Darkness, and Link combine with Mario so he can hold the Master Sword and beat Ganendorf in Episode 75.
  • Continuity Nod:
    • Wario's job at the printer shop reappears in Act I as his Summer Job. This however leaves us to wonder if Waluigi is still employed.
    • Luigi's Mansion is mentioned in Season 4.
    • Season 5 contains a bunch of characters and locations from previous seasons as part of being the last season.
  • Dark World: Ganon trapped Link in the Dark Realm. It is also revealed that Ganon plans to merge the dark realm and real world.
  • Dead Serious: When someone as famous as Link dies, you know things are getting serious.
  • Determinator: Mario is this so much in Season 5 that it impresses Merlin. It's all Justified because of what's at stake.
  • Did You Actually Believe...?: While speaking with the Wario Bros. and their attempt to join him in Episode 26, Nox Decious calls out this trope by name.
    • The Narrator addressing the viewers about the fake ending of Season One: "Did you think that was the real ending? You're stupid, you must be one of those stupid people!".
  • Disc-One Final Boss: Bowser serves as this for The Movie and the series as a whole. He was initially the Big Bad of Season One when it was initially focused on the Mario Bros but when more Nintendo characters and new, more powerful villains arrived, he was sidelined and Demoted to Dragon. He serves as this for The Movie as he is the main villain of Act I before The Darkness reveals itself as the true main villain.
  • Dismantled MacGuffin: The Nether Emblems: The Shield, the Cross and the Hilt.
  • Disney Death: Mario in the Movie
  • Disproportionate Retribution: Scott Masterson's motivation for joining Ganondorf's army was to get revenge on Donkey Kong for stealing the rights to Johnny Mushroom and the Kingdoms from him:
    Scott Masterson: Donkey Kong! You stole my band. (laughs) Now you're gonna learn what it's like to lose something you love: your life!
  • Double Vision: used often due to the limited number of actors. The most notable example is probably any scene with Mario and Merlin, which requires a split screen.
  • Easing into the Adventure: Happens in the first episodes of seasons two and three, as well as in the first act of The Movie
  • The End of the Beginning: The season three finale was named this
  • Enemy Mine: Mario and The Darkness's armys actually do this (much to everyone's surprise) to take down Ganon.
  • Enemy Within: Mr L...
  • Energy Ball: Fireballs
  • Everyone Join the Party: The Season One finale has almost every character from that season.
  • "Everybody Laughs" Ending: The fake ending of Season One was this
  • Evil Counterpart:
    • Wario and the Darkness to Mario
    • Waluigi to Luigi
    • Liquid to Snake
  • Evil Is Hammy: Most villains, most notably The Darkness.
  • Face–Heel Turn, although it's against Luigi's will
  • Evil Sorcerer: Nox Decious.
  • Faking the Dead: Wario
  • Fearful Symmetry: Just watch Episode 29...
  • Fighting from the Inside: Luigi vs. Decious
  • Fireballs: This is a Mario parody so it was pretty obvious.
  • Finger Poke of Doom: Played with in Episode 67; when Waluigi wakes up from his coma claiming he is still in perfect shape, Wario proves otherwise by simply poking him in the forehead.
  • Flash Step: After Fed Ex insults Ace of Bace, UPS literally defeats him and his group of ninjas in the blink of an eye.
  • Floating Head Syndrome / Evil Overlooker: visible in in this poster for The Movie
  • Foreshadowing:
    • In the blooper/ramblings of Episode 31; Chris (the actor of Luigi) said "Well that's the end of Decious... for now!"
    • A lot of this was done in Season 3 for The Movie.
  • Funny Background Event: Episode 55 and all following episodes are completely based around this... with NINJAS.
  • Fun with Acronyms: the Mothers And Fathers Italian Association
  • Fun with Subtitles:
    • All letters from Bowser or any other character come with subtitles, regardless of whether you understand them or not.
    • Michael Myers and Jason speak with subtitles in The Interactive Halloween.
  • Generation Xerox: A major theme for Episode 75, which focused on the similarities between Mario and Luigi and their ancestors Merlin and Nox. To drive this point home Nox even said "What are we going to do now, Merlin?". Luckily Mario and Luigi's lfe ended better than Merlin and Nox's.
  • Good Colors, Evil Colors: Mario and Wario's Beam Swords being originally blue and red made this clear (although they would later get beam swords that have their own color). This is expanded on in Season 3, where it's explained that the cores of Beam Swords actually change color depending on the wielder's morality. If the core is white, then the user is good, but if the core is black, then the user is evil. Nox Decious' personal Beam Sword, the Black Widow Blade, is crafted using black magic and thus has a black core regardless of who wields it.
  • Gotta Catch 'Em All: Ash and Brock's main intention with Pokémon. They're based more on their original characterization in the early episodes of the anime than anything else.
  • Grand Finale: Episode 75 (or its title The Super Mario Brothers) which is the longest episode of the whole show. Most episodes are close to ten minutes. This one is over an hour.
  • Greater-Scope Villain: Nox Decious serves as this for Seasons 1 and 3 as the mastermind behind Bowser and The Darkness; The Darkness serves as this for Season 4 as the true leader of The Trifecta and Ganondorf serves as this for the entire series before stepping up as the Big Bad in the final season
  • Halloween Special: Two in fact, one was a short spin off that didn't present much besides Halloween stories and only had Mario, Ash and Brock in it and the other was The Interactive Halloween (in which Freddy and Ghostface try to kill the Mario Brothers.)
  • The Heavy: Wario and Waluigi serve as the main physical threat to the Mario Bros in Season 1 as Bowser is the unseen Big Bad.
    • Wario serves as this for the first half of the show as the most recurring enemy to Mario. He is Co-Dragons to Bowser in Season 1, alongside Waluigi; a major, albeit secondary threat in Season 2 and the Big Bad in Season 3.
  • Heel–Face Turn: Wario at the end of Season 3.
  • Hero of Another Story: Every video game character in this.
  • Heroic Sacrifice: Link gives up his life to add to Mario's power in the finale.
  • Hijacked by Ganon: The Trope Namer does this, being behind most if not all the conflict of the series.
  • Hilarious Outtakes: Blame Matt (Wario) for them being so gosh darn funny.
  • Hong Kong Dub: Episode 27.
  • Hollywood Tone-Deaf: Walgina, Waluigi's Real World Girlfriend
  • Humanity Ensues: The Darkness, thanks to having a part of Mario's spirit. Thought through his life deciding that his true purpose was to kill his creator.
  • If You Won't, I Will: Subverted when Wario attempts to say this to Mario about fighting Luigi, but Mario interrupts, saying, "It has to be me."
  • I Know Mortal Kombat: In Act 1, Ash got the Mario Bros. and Peach out of prison by playing Ace Attorney for over 100 hours (as he finished playing Pokemon Platinum early).
  • "I Know You Are in There Somewhere" Fight: Variant, Mario tries this before his fight with a Brainwashed Luigi. It works at the end, though.
  • Improbable Aiming Skills: The General of the Darkness' army doesn't fight much, but when he does, he has yet to miss with a gun.
  • Infinity +1 Sword: The Nether Saber is described as such by Merlin, being the most powerful Beam Sword. Whoever wields it is guaranteed to win every fight.
  • Interrupted by the End: Episode 13 has this
  • Interspecies Romance: Between Pauline and Donkey Kong, much to Mario's disgust.
  • Irony: Waluigi reveals that he and Walgina broke him because she wanted him to stop wearing purple despite the fact she wears purple herself.
  • Ironic Echo: "Snap out of this fantasy, and come back to reality."
  • It's All My Fault: Mario says this during the season 2 premiere. Because the warp pipes are not working, Mario says it's his fault that there are no heroes in their world.
  • It Has Been an Honor:
    • Luigi says this to Mario in episode 43, when Mario and Luigi discover that they are the only two people that can go up against the Big Bad Wario, as they might not survive.
    • Also happens in Act II Part 4 with Solid Snake to Mario
  • It's Personal: Wario wanting to destroy Mario in Season 3
  • Jerkass:
    • Bob and Joe of RMA Studios.
    • Wario and Waluigi in ealier seasons.
    • Snake can sometimes be this too but then becomes Jerk with a Heart of Gold.
    • Mario himself has even shown this throughout the show, but it shows up most prominently in Season 4.
  • Killed Off for Real: By the end of Season 5, the people well and truly killed off are Ganondorf, Nox Decious, Darkness, Blaire Vherestorm, Scott Masterson, Liquid Snake, Tommy Vercetti, Merlin and Link. (although Link will reincarnate sometime in the future)
  • Knight of Cerebus: Once Link shows up, the story kicks off and the Bros. and friends face progressively darker foes throughout the rest of the series.
  • Language of Magic: the counter curse in Act 2 Part 6 of The Movie
  • Large Ham:
    • Any role played by Richard
    • Wario is this trope in earlier seasons, and has become one again after season three where he was a Big Bad.
    • Max Payne appears to be this so far.
  • Laser Blade: Like in Super Smash Bros., they are called Beam Swords.
    • Lampshaded by Wario and Mario in Season 4
    Wario: So why do we fight with Li.... uhh I mean Beam Swords?
    Mario: I don't know. They use them in Super Smash Brothers.
  • Lighter and Softer: Season 4 until The Darkness and Decious return. Previously we've dealt with evil copies of Mario and Luigi, Bowser, and a temporarily evil Wario. Now we have comic relief ninjas.
  • Line-of-Sight Name: Snake gets one in The Interactive Adventure. "My name is um... Stapler...Cheeto!"
  • Loony Fan: More like a Crazy-obsessed-stalker-who-makes-you-unable-to-sleep-at-night Fan, as evidenced by her "Let's Get Hammered" Mario T-Shirt.
  • MacGuffin: The Nether Saber and the Truth Stone.
    • And then the Master Sword in Season 5. Since it's the only thing that can defeat Ganon.
  • Man Behind the Man: Ganondorf is effectively behind most of the major conflict in the series; he was involved in the first revival of Nox Decious, who in turn created the Darkness, who in turn created the Trifecta, who paved the way for Ganondorf and his army. The Darkness serves as this for The Trifecta in Season 4.
  • Mandatory Line: Doug Orofino gets only one line as Waluigi in Episode 26, much to his annoyance as shown in the bloopers.
    Wario: "Just keep your mouth shut and let me do all the talking!" Waluigi: "Fine!"
  • Manipulative Bastard: In Season Four, Professor Oak willingly tricks Gary and Brock into doing several mundane tasks for him just so they could find out from him which one of them sucks more. Oak eventually claims they equally suck for not turning down the tasks. As a result the two fight over which one of them hates each other the most which Oak uses to his advantage once more.
  • Medium Awareness: Plenty. For example, Wario complains about being unable to get a flashback.
  • Merged Reality: Ganondorf's real plan is to combine the Real World and the Dark Realm.
  • Mind Rape: Luigi with his scenes with Decious...
  • Mood Whiplash: As mentioned above, the first season was entirely focused on comedy, while becoming serious from Season Two onwards.
  • Motive Rant: Happens quite often. A good example is FedEx's confrontation with UPS in Episode 13.
  • The Movie: The Movie. Operation Blind Storm has the spirit of this trope, but isn't as long as the movie.
    • Many consider the finale, Episode 75 as a movie due it's long length.
  • Mutual Kill: Nox and the Darkness.
  • Mythology Gag: In Season Three, Link drinks expired milk. He temporarily loses his ability to speak and goes to bed shouting like he does in his own series. In Season Four, Wario and Mona end up in a relationship. In the WarioWare games, Mona actually has something for Wario. (It should also be noted Wario's actor Matt and Mona's actor Erin are boyfriend and girlfriend).
  • Names to Run Away from Really Fast: Nox Decious, The Darkness
  • New Years Episode: In which Mario and Luigi celebrate the New Year and Wario is desperate to join them (noting the episode is non canon as a reason to join them) but is left with a hobo.
  • Nice Job Fixing It, Villain: In Episode 74, a ninja taunts Wario (who had just abandoned his friends) and his threats sufficiently piss off Wario to the point where he rejoins his friends.
  • Nightmare Sequence: Luigi has two concerning Nox Decious
  • Ninja: Though they are very lazy and stupid. But make for a Funny Background Event.
  • New Job Episode: In Season One, where Mario and Luigi are tired of plumbing, decide to try out a bunch of jobs but fail every time.
  • No Name Given: The "Package Delivery Men" are only known by the company the represent.
  • Not Quite Dead: The Darkness TWICE as of Season 4
    • Liquid Snake in Season 4 only to die later.
    • Mario in Act II
  • Oh, Crap!: "I said" courtesy of Max Payne
  • Overly Long Gag: Mario's Big "NO!" after a crazy fan stole his hat.
  • Once an Episode:
    • In the first season it was the mailbox and the running up the hill
    • And also, they recently had the Subscribe Voice at the end of the episodes.
  • The Only One Allowed to Defeat You: The reason Wario killed Nox Decious
  • Ooh, Me Accent's Slipping: Played with. In season three, after Mario's accent vanishes, Luigi notices it and says they're beginning to sound more Irish. Cue Mario denying it... in an Irish Accent. And in the final two seasons, Mario tends to speak in Rich Alvarez's normal speaking voice quite a few times.
  • Pink Mist: Appears after Liquid get killed here.
  • Pirates: In The Interactive Adventure and are part of The Darkness's Army in Season Five. They're effective to an extent but some of them tend to get drunk on rum.
  • Please Subscribe to Our Channel: A pretty unique one too as Richard performs a funny voice at the end of every episode (and video for that matter) that goes like this:
    "Please Subscribe, it's free and easy. Just click the Yellow Button and for every time you subscribe to Richalvarez *followed by a witty line or joke*"
  • Precision F-Strike: Tommy Vercetti has this reaction to seeing Brock and Gary in the Season 5 premiere.
    Tommy: Who the f*ck are these idiots?!?!
  • Pre-Mortem One-Liner: "You picked the wrong day to be an asshole". Waluigi to Blaire Vherestorm
  • Private Eye Monologue: Max Payne says his out loud, parodied in that Max has one in the games.
  • Public Domain Soundtrack: Dance of the Knights from Prokofiev's Romeo and Juliet Ballet is used as Nox Decious' theme.
  • Put on a Bus / Written-In Absence: Happens quite a bit.
    • Waluigi has this happen when Waluigi gives the others his powers and falls into a coma, thanks to the actor living quite far away. He then returns in Season 5 only for him to overstrain himself and become stuck in and out of consciousness.
    • Brock, played by Austin, has the same problem but managed to come back for Season 4 and 5.
    • Peach and Walgina had this happen for a different reason—they've since broken up with the main actors.
    • Link as claimed by Ganon in Season 5 got trapped in the dark realm by him.
  • Rage Against the Mentor: Mario to Merlin on Link's death
  • Refugee from TV Land: The reason Mario and Luigi first come to the Real World is for a vacation.
  • Real Life Writes the Plot: Also happens quite a bit.
    • Brock's actor moving to San Francisco.
    • Doug's (Waluigi) trip to Australia.
    • Peach's actress was Richard's (now ex) girlfriend, and Walgina's actress (also ex) was Doug's. Mona's actress is also Matt's (Wario) girlfriend.
  • Rule of Funny: Why Ganondorf's voice (done by Matt) is so ridiculous and Hammy.
    • But is no longer as serious as he is now Season Five's main villain.
  • Running Gag: Plenty.
    • Taco Lax being mentioned by either Wario or Waluigi. Sometimes both of them.
    • Pokeballs never work
    • DK chases the Wario Bros.
    • Gary calls everyone a loser
    • Donkey Kong wails every time someone mentions Pauline's death
    • In the bloopers:
      • the "20 Dollars" joke
      • Matt shouting out random things that appear on the camera. (For example, "BEN & JERRY'S!" and "LUMBERRRRRRRR!")
      • "I roll with gangs", a joke originally made in Episode 1's bloopers.
      • There's also "From Mona?", which started from a joke in Episode 51's bloopers. It later appears in the bloopers for Episode 53, and seems to be on it's way to becoming a Running Gag.
  • Sad-Times Montage: Episode 2, after Luigi leaves
  • School Is for Losers: Brock reasons his return from Reffing School was because "School is for Slow-pokes".
    • Subverted when he revealed in Season Four that he finished Reffing school with honours.
  • Sdrawkcab Alias: Nilrem (Merlin)
  • Screw This, I'm Outta Here: Ness performs this, also pointing out he's a kid
  • Series Fauxnale: It was originally intended for Stupid Mario Brothers: The Movie to be the series finale after many crucial cast members moved away, ending the series after three seasons and a movie. However, after realising that enough cast members remained in town to keep the series viable for continuation, Richalvarez decided to continue the series, giving it two more seasons and three more specials.
  • Sharing a Body: Luigi and Nox Decious not only share a body but used to share a mind.
  • Shout-Out:
    Link: You can have my sword and shield.
    Peach: And you have my umbrella.
    Donkey Kong: And you have my fists.
    Ash: Poké Balls, that is....
    • Plus from Season 5:
    Snake: Uggh You're late
    Donkey Kong: *Crazy rambling*
    Ness: DK says "A Gorilla is never late, neither is he early and you're lucky if he arrives at all."
    Mario: Ganon under orders of the peoples of free Earth I hereby outlaw you from this planet.
    The League: *bursts into laughter*
    Ganondorf: Surely that's not the best you can do?
    Mario: Oh I can do better and don't call me Shirley
  • Say My Name: Happens during Mario's battle with Nox Decious.
  • Sliding Scale of Silliness vs. Seriousness: Each season was either silly or serious thanks to an Unpleasable Fanbase.
    • It's been lampshaded plenty of times and in episode 57, Mario claims that due to being serious when funny and funny when serious that he's decided to be seriously funny.
  • Soul Jar: Luigi
  • Spin-Off:
    • Though there's no official one, the Ash and Brock series comes close.
    • Richard has also said on multiple occasions that he plans for a UPS Spin Off (now confirmed as an Interactive Adventure).
    • Austin (Brock) and Daen (Professor Oak) produced their own spin-off name ''Stupid Pokemon Friends'' that follows on Brock and Oak's adventures after StMB ends. Sadly conflicts with Richard and RMA resulted in it being cancelled after one episode.
  • Spirit Advisor: Merlin acts as this during Season 5. The Darkness and Link join him in the finale.
  • Spiritual Successor:
    • "Super Mario News" on Machinima
    • The actors actually make occasional videos for Machinima, like the "Super Mario Drive Thru" series, "Dr. Mario Begins", "Super Mario Chat Roulette 1 & 2" and the "Snez Pez" series.
    • On a similar note, Richalvarez's next big web series since this one, The Plumber Knight Returns fits the bill.
  • Spoiler Opening: The opening sequences for Seasons 2 and 3. Which is why there's no opening for Season 4 or 5.
  • The Stinger: After the credits in the finale, there's a short scene of Mario, Luigi, Wario, and Waluigi all enjoying some milk.
  • Super Mode: Like in the games, Mario + Fire Flower = Fire Mario
  • Taking You with Me: In their second fight, Liquid shoots Snake after being shot himself while calling out this trope by name, but fails as Snake was wearing a bulletproof vest.
  • Talking to Themself: The actors are all the main actors' friends. This leaves them with a lot of doubling up.
  • Terrible Interviewees Montage: Mario and Luigi suffer this while trying to start the band in Season 1.
  • That Man Is Dead: Luigi is dead! But Mr L has just been born!
  • The Man Behind the Man / The Big Bad Shuffle: The Darkness and Decious both seem to take turns antagonizing the other, while also antagonizing the heroes.
  • I Am Old And Will Be Gone... Bitch
  • Throwing Your Sword Always Works: during Wario's battle with the Darkness in The Movie, Wario pretends to be dead and hurls his Beam Saber through the Darkness' gut, which seemingly kills him. However, as Waluigi failed to bestow a counter-curse upon Wario before his prolonged absence, the Darkness is still immortal and gets back up later on.
    Darkness: Gee, that stung!
  • Title Drop: Bowser in Act II: "THOSE, STUPID, MARIO BROTHERS!".
  • Toilet Humour: Quite a bit. While justified by the source material (as Wario has a fart attack), it is disliked by several fans. This caused a funny Take That! by Julian (Snake) over the forums:
    If you guys hate toilet humor, then you're going to hate the next episode when I eat poop and smear it on my face while throwing it at Mario's face and then swimming in a diarrhea fountain.
  • Took a Level in Badass: Mario in "The Interactive Adventure." He then Lampshades this.

  • Villains Out Shopping: In episode 65, Nox Decious plans to finish reading his latest issue of Sports Illustrated while Zubashi finishes preparing the troops... until Zubashi reveals he accidentally flushed it down the toilet.
    Nox Decious: You WHAT?! That was my limited edition swimsuit edition with bonus NFL coverage!
  • Waxing Lyrical: Done in this video of deleted scenes from Episode 36 between Wario and Ash, using the Pokemon theme song:
  • Wham Line: Episode 60 gives us the one which reveals how the Darkness survived the battle with Wario:
