SuperMarioGlitchy3, more commonly abbreviated as SMG3, is the overall main antagonist of the SMG4 series.
He serves as one of two main antagonists of the first three seasons of the series (alongside Bowser), the main antagonist of Season 4, Season 5 and Season 6, a minor antagonist of Season 7 and Season 8, the secondary antagonist of Season 9, and the overall main antagonist of Season 10, serving as the main antagonist of The YouTube Arc.
He is SMG4's evil doppelganger who was first discovered trying to copy SMG4's videos and had attempted to kill him ever since. He (and Wario) were the people responsible for turning Waluigi back to normal at the end of WOTFI 2018. After the T-Pose incidents, he retired from villainy to start a therapy television series called Dr. SMG3, which was first seen during the climax of the Waluigi Arc. It lasted until A Day In The Life Of Everyone where his therapy show was cancelled, and later started his own production company which was later destroyed, forcing him to go back to his dark ways. He eventually formed a plot to seize Susan Wojcicki's YouTube Remote and used its power to erase SMG4 from existence and take his place as a YouTube juggernaut.
He lived in a colossal fortress located in an unknown realm, and his best friend was Nintendofan996 (Nintendofan997's doppelganger). He also earned a psychiatric degree before the events of SMG4 VS SMG3.
As of Season 10, SMG3 now has original voice lines similar to SMG4's in the previous season. However, his voice actor was unknown as Luke and Kevin have been keeping SMG3's voice actor a secret until SMG4: War Of The Fat Italians 2020 where his voice actor was later revealed to be James Bailey. He was previously voiced by Luke Lerdwichagul in Mario's EXTRAS: MarioTube 2 on TheAwesomeMario.
After many challenges and a rap battle, SMG3 was defeated and sent to the Internet Graveyard for his abusive usage of the YouTube Remote and for sending Susan and Mario's friends to this place. He made one last attempt in making his career again by starting a podcast and interviewing a Ugandan Knuckles, but was then attacked by it. However, James Bailey revealed via Twitter that he will return someday in the future videos but how he would escape the Internet Graveyard (and the methods he would use to do so) is currently unexplained.
Being the arch-rival to SMG4, SMG3 was slightly the opposite of SMG4 in terms of appearance. His shirt and cap were of a darker blue color, while his overalls were black, also retaining gold buttons. His Garry's Mod model showed a skull emblem on his cap that wasn't visible on his Super Mario 64 model.
In SMG4: Mario's Spicy Day 🔥 onward, he spoke in a flamboyant Australian accent.
Background and Super Mario 64 Bloopers: SMG4 VS SMG3
Most of SMG3's past, including his childhood, is unknown. At some point, he enrolled at a meme school and there he met SMG4. Throughout his time at the "Meme School", SMG3 became jealous of SMG4's popularity and how good he was at making memes, resulting in the former briefly becoming obsessed with trying to achieve fame.
Years later, after SMG4 started his YouTube channel, SMG3 began fragrantly plagiarizing his videos in an attempt to steal his fame. This attempt was short-lived, however, as SMG4 figured out what was happening and confronted SMG3 at his hideout along with his friends. SMG3 ultimately lost the fight and was thrown out of his building. As a result of having his chance at fame stolen from him, SMG3 became SMG4's arch-enemy, not stopping his evil acts until he was successful at destroying the YouTuber's reputation and his life.
In his first appearances, SMG3 was prone to being a very arrogant, selfish, stubborn, vain, and merciless bad guy who appeared to be an incompetent villain, using useless tricks to defeat his foes, but with very little success. In his later appearances, he began to show a much darker personality, now that he was promoted to being the main antagonist. Despite appearing to be more evil, he continued his incompetent acts and usually tried to do something unusual to save himself, commonly hurting him in the process, yet protecting or enabling him to escape successfully. Like Francis before him, he was also a coward, as he only relied on a strong object to protect himself rather than getting into a physical fight.
Like SMG4, SMG3 seemed to be a showoff on Bowser whenever they bother on something they think they are better with. He always desired to do anything that got rid of SMG4 and killing everyone in his path that defends him.
In SMG3's mind, he is meant to be the evilest person in the world, not Waluigi; this was why he helped Wario and the rest of the heroes during the end of the Waluigi Arc.
However, aside from his evil traits and stints as a villain, SMG3 has proven himself to be a bumbling, goofy dork much like his rival; his cameo appearances showed him doing normal hobbies, including eating chicken, taking long naps, reading JB mags, even starting a club for villains. For some reason, he even enjoyed partying, though he was also somewhat bratty and his behavior was akin to a crybaby.
In the YouTube Arc, SMG3 became a much more despicable individual. His grudge against SMG4 increased beyond its limit, but to an extremely heinous degree; he had no qualms in not only trying to rip him off, but also outright erase him from existence, and violently lashed out and retaliated to any suggestion that SMG4 is better than him. He was very short-tempered and aggressive even to his own gang, as he bullied and degraded Whimpu, had a complete lack of sympathy for JubJub when he missed his older brother Fishy Boopkins, and even electrocuted Belle when she badmouthed him. SMG3 also showed total inability to acknowledge or take responsibility for his own poor ability in directing videos, pinning all the blame on his gang and claiming that he can do better than SMG4, despite all other evidence to the contrary. He also had an utter lack of flexibility; instead of playing his gang's personalities and traits to their fullest, he forced them to act exactly like their counterparts, despite all of him being clearly unfit for their roles. He also had unawareness of recent events, as he thought Bob still has a rapping career even though the latter had stopped rapping; he made his Bob counterpart, Rob, promote the latter's rapping album.
This increased villainy of his eventually backfired on him, as SMG4's Gang was able to remind his gang of his poor and inhumane treatment, causing them to turn against him. When he was defeated and backed into a corner, he cowardly tried to claim that his actions were nothing but a mere prank in order to appeal to the good nature of his enemies, only to be ignored by all of them and banished to the Internet Graveyard. He then proceeded to show that he learned nothing in trying to create a podcast of his own, and ended up getting brutally attacked by Ugandan Knuckles.
Once again, he is the main antagonist. He battles with Mario, but when he is distracted, a magic rock restored Mario's memories. Mario gained the upper hand and knocked SMG3 away, much to the SMG4 twin's dismay.
As the main antagonist, SMG3 appears once again without Bowser this time. He proceeded to trap SMG4 and the others in a nightmare world which has their known enemies haunting them. However, they all escaped and found SMG3 relaxing in a bathroom reading Justin Bieber magazines where they then beat him up.
He appears to take over the world and battle Mario. However, upon seeing him naked, SMG3 decides to postpone his plans. He later appears sitting on a toilet.
He has a brief cameo when SMG4 and Mario are fighting a dragon.
Reprising his role as the main antagonist, SMG3 proceeds to create a master plan that will destroy SMG4 by bringing back all the enemies to life which somehow involves the Nightmare Stone's usage. Ultimately, the plan fails.
SMG3 proceeds to hire a teleporting hitman to destroy SMG4 and the others. However, the plan failed when the hitman accidentally died.
In this blooper, SMG3 gives Mario a bomb disguised as a cake for Starman3's celebration. It then blows up Peach's Castle, ruining the celebration. This is one of the rare moments where SMG3 wins in the end.
Once again as the main antagonist, SMG3 revives The Monster (called Pepsi by Mario). He seems to do a decent amount of damage to the Kingdom. But when the monster falls down, he loses again.
He appears as one of the people whom Luigi asked for the way to Mario's House because Mario kicked him super far out of the house. However, SMG3 ignored him.
In this episode, he has appointed the main antagonist role by Bowser's boss, making Bowser the secondary antagonist and his partner. They tried to do evil schemes together but they were small stuff. They eventually decide to steal the princess just like in their original plans. However, when attempting to do so, they encountered her taking a bath where she asked for shampoo. She eventually found them in horror and when Mario found out, he immediately kicked them out of the castle.
Back to being the secondary antagonist, SMG3 is working with a YouTube noob who tries to destroy SMG4 because his videos were unpopular and wanted to know from him how to become like SMG4. SMG3 back-stabs him just to save SMG4, proving he is less evil in this episode.
Once again, he is the main antagonist. He works with a crazy Japanese guy who explodes when SMG4 finds them. When SMG3 sets the island to explode and he sends in the submarine, it is instead a truck (which sinks), so he gets trapped along with the others when they are about to die.
He isn't ready to give up yet though. He then uses a robotic suit to destroy SMG4, Mario, Luigi, and Peach. He fails to get Mario and SMG4 but then goes to Peach and Luigi. Much to SMG3’s dismay, he throws Peach at his screen, causing him to fall. He finally surrenders and accepts his fate, but SMG4 realizes the robot is indestructible, so they all go in SMG3's robotic suit. Soon after, the island explodes and the suit is flung out of it into the water.
As the secondary antagonist, SMG3 helps a crazed, angry Enzo assassinate Mario for eternity after he ruins his birthday party (thanks to Steve being "invited" to the first party). However, SMG3 goes on SMG4 and Mario's side as Roprinplup14 counts while playing hide and seek, because if he finds them he takes them out. He manages to escape from Roprinplup14's extreme up-to-eleven terror, while he gets arrested by a police officer, pushing his rage up twice.
Since then, SMG3 has made small appearances and more before (including in Super Mario 64 Bloopers: 2 Hands 1 Job).
Returning as the catalyst villain. SMG3 created the Ztar to destroy the Mushroom Kingdom but it escaped to Delfino Plaza because it accidentally fused with Toad. After its attack on Mario, Bowser, SMG4, and SMG3, they made Good Star to counter Ztar, with Bowser using Old Man Hobo as the fusion material. Although they succeeded in defeating Ztar, it is immortal so instead, they tied it to a boat and had Good Star watch over it.
He and Bowser are teamed up as the main antagonists. They have joined Hobowarts, a wizard academy, both being on Team Slytherbastards. SMG3 and SMG4's rivalry is shown in an almost close way as in SMG4 vs. SMG3, unlike in Bad Stars. When SMG4 and Mario tried to escape, they overheard SMG3 questioning the wizard rock about why the rock invited SMG4 there. Even though SMG4 tries to clear stuff up by trying to become best friends with him, it turns into a fight, leading into a competition.
After both of them lose to Po and Steve (however they weren't in the competition, making it strange), SMG3 turns into an inverted form following a mistake invoked by SMG4 saying they could still be best friends; he is then defeated by SMG4 via the "flippy and old sand" (which is Mario's idea to make SMG4 beat SMG3), destroying the academy from the force of the explosion.
He appears as the leader of a group of bad guys. Dr. Eggman tries to join it, but SMG3 doesn't want him in his club, causing Eggman to do evil stuff. However, SMG3 still doesn't let him in the club (as all he just did is stealing a lollipop from Stacy's baby (which is actually a police officer), and destroy someone's lunch). Eggman then makes a demon (Perfect Chaos) and SMG3 says that is the evilest thing in the world and then he runs away in a panic because the demon is going to kill everyone (but Toadwardo destroys it).
He makes a cameo appearance where he tries to be a hero by riding the Koopa Clown Car to crash onto Roprinplup14. However, he missed him and fainted after crashing miserably.
He asks Mario where to buy "pet Russian Dolphins", implying that he likes them.
Mario tried to kill him by putting him (with Bowser) in the lake of the garden of Peach's Castle, thinking he is responsible for the appearance of a lot of evil pipes in that same garden. However, the real commander of the invasion is the King Pipe, who led a revolt against Mario for incompetent plumbing.
SMG3 appears at Mario and SMG4's talking room as a cameo where he complains about how he isn't invited to the party. SMG4 then tells him that he only appeared in Bad Stars, upsetting him.
He appears amazed to see SMG4's fans being angry at SMG4 because he got an idea block.
He wakes up after sleeping in a dump/"SECRET LAIR" when he sees the "Bad Star" getting humped by Mario flying through the sky. He then goes back to sleep.
He is briefly seen in an armchair, watching Mario naked doing pole dance on a tree.
SMG3 denies Bowser's help call when he wants to get off the Sky Observatory. After Bowser says that he used his toothbrush as a toilet cleaner again, he flips out and angrily starts mashing the keyboard, blocking a wormhole. Bowser smugly notes this works every time.
He created a Crazy Koopa that steals shells before being blown away by the shell-less Bowser.
He is seen trying to do an evil plan, but Bowser is doing retarded stuff. Shortly after, SMG3 is being chased by the police and crashes outside the bank (due to an old lady). SMG3 tells Bowser to attack the enemy, but Bowser crashes into the old lady, not the cop.
He followed SMG4 and Mario who crashed at Snowman's Land. He tries to attack them both with another one of his machines, but Mario appears on it and makes SMG3 fire a laser at a slope, causing an avalanche. SMG3 runs into Old Gramp's House, where SMG4 is taking shelter. The avalanche blocks the entrance to the house, so the two are trapped together. They slowly lose their minds (due to hunger), and go crazy, and later start to have sex. Mario gets in (thanks to Old Man Hobo's rocket launcher) and takes both SMG3 and SMG4 back home.
He appears in a skit with Toast Guy
In the blooper "SMG3's Gauntlet of Gloom", he is once more the main antagonist. SMG3 is revealed to have recorded various events that made SMG4 look like an idiot. He then escapes to his fortress, where he deploys a large set of booby traps, while he prepares to post the recording on YouTube to ruin SMG4's career, completely oblivious to the fact that Bowser also wants to steal the footage.
Mario and SMG4 managed to reach his lair and confronts him, though the footage had reached 95%. While Mario and SMG4 manage to survive the booby-trapped hallway, though not much, the uploading is at 99% and it appears that SMG3's plan would succeed. However, much to SMG3's frustration, Bowser drops from the ceiling and destroys the computer. Infuriated, SMG3 sets his fortress to self-destruct, while he jumps from a window, escaping but falling to his supposed death. This episode is so far the only one that truly showed SMG3 being a threatening villain.
He is again the main antagonist. SMG3 is the king of the Kushroom Mingdom. He attempts to capture Mario and Luigi and actually does capture them. He is able to obtain his own kingdom after making a wish using Grand Dad, though he somehow did not create a replica of Mario and Luigi, even though he created a replica of Bowser and Peach.
SMG3 wants Mario and Luigi to "complete his kingdom" because apparently, he "needs the real idiot brothers to complete the set" However, the Bowser from the Kushroom Mingdom comes and has the same intentions as normal Bowser. While SMG3 is caught up in getting Bowser to go away, Mario and Luigi escape. This episode is a different take on SMG3 because he is never a king in a kingdom before.
Due to his acts in the previous video, he is nominated in the Best Villain Award 2017 for littering.
In this episode, he is walking down an alleyway where he encounters Picolas Cage holding a gun threatening to shoot him, telling SMG3 to eat his fruits and vegetables. Panicked, SMG3 promises that he will eat his fruits and vegetables, and Picolas Cage, who is glad to hear this, backs off.
SMG3 is one of the contestants, though he is only seen on Floor 5. He is shown jumping from mushroom to mushroom when one falls and starts collapsing into the lava. Left with no other options, SMG3 decides to jump to a mushroom near the exit. Though he is just about to make it, Bowser hops along and stomps on him, causing him to fall into the lava, eliminating him from the challenge.
SMG3 is seen to be the main antagonist yet again. SMG3 kidnaps everyone and pits them against each other for prize money. After Mario emerges victorious in every challenge, SMG3 reveals that it is just an experiment to see who he would hire as an enforcer, but the red plumber throws a rock at the latter, causing him to get angry and engage Mario in a fight. Bob, who then randomly shows up, presses random buttons in SMG3's throne, opening a door that reveals the defeated participants, who then angrily burn SMG3 and hang him at the entrance to Peach's Castle.
SMG3, dressed as Darth Vader, steals Dream Land's food supply out of pure evil intentions (and because he is poor and couldn't afford to actually buy food). Mario offers to help him, only to be kidding and kick him off the Halberd, defeating him.
SMG3 is visited by Saiko, who is attempting to sell rocks to him. At first, he refuses, but when Saiko forces her way in his apartment and threatens him, he angrily agrees to buy whatever she's selling. When Saiko reveals that she's selling rocks, SMG3 thinks she's joking and laughs uncontrollably, but when Saiko states that SMG4 bought 1,000,000 rocks (which means he's better), SMG3 remembers his rivalry with SMG4 and agrees to buy 2,000,000 rocks off Saiko.
SMG3 makes a surprise appearance at the end, as the therapist that Wario hired for him and Waluigi to reconcile. The session works but SMG3 is unenthusiastic about it and joins the other characters as they leave to play video games.
SMG3 is awarded The Mushroom Kingdom Award for saving the world from Waluigi with his therapy. SMG3 taunts SMG4 over this, who gets angry and starts attacking him.
He is once again the main antagonist. With the help from Wario and Waluigi, he captures Mario. Now having employed Wario and Waluigi as his minions, he steals all the internet routers in the Mushroom Kingdom, with his plan being to create a site centered around himself, where people can only watch his videos. Upon doing so, he causes an apocalypse with almost everyone understandably nearly losing (or all of) their sanity, due to needing the internet to survive. With the joint effort of SMG4, Mario, Luigi, Toad, and The Wild Childs (Meggy, Tari, and Saiko), he is defeated yet again.
SMG3 continues to run his Dr. Phil-style show. He is revealed to have kidnapped Bowser for over a month to be a guest on the show. His show is also eventually canceled, forcing SMG3 to revert back to his evil ways.
Mario finds SMG3 digging a tunnel to Area 51. It is later revealed in SMG4: The Day SMG4 Posted Cringe that he went there to steal all the YouTubers' passwords. He posts cringe to try to destroy SMG4's channel and blackmails YouTubers to defend himself. Unfortunately, his evil scheme is foiled by SMG4, Mario, and Saiko and he is forced to watch 10 Hours of UwU AMSR video, much to his dismay.
SMG3 attempted to hack SMG4's computer by locking it, but his plans were foiled by a now-intelligent Mario and he is banned (presumably on Club Penguin) for doing so.
He appears as SMG4's nightmare.
He appears in one of the challenges where either SMG4 or Mario made him laugh. Naturally biased towards SMG4, he laughed whenever Mario did something to SMG4, causing Mario to win that challenge.
In SMG4: Mario's Spicy Day, SMG3 tricks Mario with a spaghetti offer so that he can be featured on his company. He records multiple videos with Mario which later, SMG4 discovers thinking SMG3 is up to something sinister. Eventually, SMG4 destroys Snitch Productions thinking he had foiled his plan. SMG3 explains all he wanted to do is to entertain people and remarks on how successful SMG4 is in school while he is always below him in popularity and ranking. Realizing his mistakes, SMG4 tries to apologize but this fails. SMG3 then warns SMG4 that he will come back, disappearing without a trace. A few moments later, SMG3 comes from behind, kicking SMG4 in the balls. The video ends with SMG3 levitating up into the air, mocking him.
SMG3 starts an audition for a play that loosely reenacts the episodes, SMG4: If Mario Was In... Splatoon 2, SMG4: Mario Gets His PINGAS Stuck In The Door, and the story arcs of the SMG4's series while being disguised as a Cromulon from Rick and Morty. He has chosen the actors who are trying to get a role in the play, including Mario, Belle Fontiere, JubJub Boopkins, Rob the Scarecrow, Whimpu, a Luigi Doll, and a watermelon wearing Meggy's headgear, who had gotten the roles. After the play, the SMG4 cast realized the reenactments weren't an original play and it turns out to be a production of Snitch Productions, and SMG4 ran off to find SMG3, who he knew had written the play.
After when both groups of SMG4 and SMG3 escalated into a fight. Mario then was able to stop the bickering between the two content creators and led to a truce between two factions (although SMG3 still had a grudge). The two factions finally came to an end, calling for peace with each other, and both went their ways.
At SMG3's base, SMG3 and his crew are planning on stealing the YouTube Remote from Youtube's headquarters. SMG3 managed to get Mario to join his plan by having the latter think of Greg's death in SMG4: Stupid Mario Arcade. The gang then attempted to obtain the remote but failed after they were caught by Susan Wojcicki and banned from the headquarters. Luckily, Shroomy had stolen the remote as his evil counterpart, triggered by Mario throwing a demon mask at him. However, Mario felt betrayed by SMG3 after he discovered that the latter was planning on using the remote to delete SMG4 from existence. Before Mario could stop SMG3, the head of Snitch Productions used the remote to summon the Content ID, kidnapping Mario so he could be sent to the Internet Graveyard.
SMG3 and his gang developed a plan to erase the events of prior SMG4 episodes. Each member would jump into portals that took them to the debut episodes of their counterparts in SMG4's gang. In those episodes, they would prevent their SMG4 counterparts from ever meeting Mario. SMG3 demonstrated this effect by having Tinky Winky throw Frankie out of the latter's debut episode, sending Frankie to the Internet Graveyard. But as he prepared to enter the portal for Super Mario 64 Bloopers: Account Loss, SMG3 was confronted by SMG4's gang. SMG4 ordered his gang to follow their counterparts into the portals in an attempt to protect their current timeline, while Mario stayed behind to try freeing the Youtube Remote. Nevertheless, SMG3 and his gang were able to succeed in their plan. By preventing the past versions of Tari, Bob, Saiko, Fishy Boopkins, Luigi, Meggy, and SMG4 from forming relationships with Mario, the SMG3 gang has successfully deleted the current iterations of SMG4's gang from their world, sending the latter to the Internet Graveyard alongside Susan Wojcicki.
SMG3's gang was tasked by SMG3 to act like their SMG4 counterparts in a new video. However, with the exception of Melony, most of the cast didn't follow SMG3's instructions. Later, after Mario was freed from the Youtube Remote's freeze to chase SMG3, the cast didn't bother pursuing the former. Nevertheless, Luigi Doll was able to help SMG3 stop Mario after being given the Youtube Remote, having previously been tasked to buy a hot dog for SMG3. By summoning lots of Content IDs to kidnap Mario, Luigi Doll prevented SMG3 from getting defeated by his pursuer, albeit not knowing Mario stole his phone.
SMG3's gang is shown acting in a video shoot in front of Peach's Castle, shortly before SMG4's gang and Susan Wojcicki shows up to stop SMG3. However, upon being pinned by Susan, SMG3 presses the "factory reset" button on the Youtube Remote, causing its spirit to possess JubJub Boopkins. The spirit then demands both sides to participate in challenges to determine if wither SMG4 or SMG3 is worthy of the channel.
A variety of challenges occur, each consisting of someone from SMG3's Gang against someone from SMG4's Gang. SMG4 and SMG3 each try to pronounce Susan's surname, surviving their encounter with The Wario Apparition, and making the spiciest meme. After all the challenges, SMG3 offers to present his evil monologue about his past, but he instead puts it in the form of a play. He then grabs Fishy Boopkins to come up and threatens JubJub to give him the remote by dropping Fishy Boopkins off the building, JubJub expels the remote as SMG3 later catches it. SMG3 then starts a rap battle where SMG4's gang eventually manages to convince SMG3's gang of the truth about their employer. This causes them to turn against SMG3, siding with SMG4 in the process.
After defeating SMG3, the gangs manage to retrieve the remote back from SMG3. SMG4 then unfreezes Susan for her to summon a Content ID to banish SMG3 to the Internet Graveyard. Once SMG3 is banished to the Internet Graveyard, his former allies celebrate their victory and friendship with their SMG4 counterparts.
Meanwhile, in the Internet Graveyard, SMG3 starts his new podcast show with his new guest, Ugandan Knuckles, only for Knuckles to refuse and attack him after SMG3 questions the former if he wants to hear his rap. According to James Bailey on Twitter, SMG3 will return to get revenge someday in future videos.
Before his banishment to the graveyard, it has been revealed in this episode that SMG3 paid E. Gadd to make alternate versions of the cast, in case his Anti-Cast betrayed him. When E. Gadd called him to ask about his final payment, SMG3 was unable to pay E. Gadd because he got banished to the Internet Graveyard by Susan Wojcicki. As a result, E. Gadd threw away the no-texture clones of the SMG4 cast in the garbage, where they became sentient and swore vengeance. (This is also the proof that SMG3 has survived from Ugandan Knuckles' attack)
SMG3 makes a cameo in R64: Idiot karts 101 as one of Mario's victims to be run over. He appeared briefly in SMG4: Stupid Paper Mario trying to halt the group but ends up getting run over. In SMG4: Super Challenge 64, he makes a cameo hosting his therapy show on TV during Boopkins' challenge. He appeared again in SMG4: Untitled Mario Video during a montage of Mario causing mischief under the Goose's control. He has made a secret cameo in SMG4: Mario And The T-Pose Virus, when Bob Bobowski gets kicked down by an angry Mario, SMG3 could be seen infected. In SMG4: Mario The Supreme Leader, he is shown to support Long SMG4. Mario then creates Bong SMG4 (Beeg SMG4 & Long SMG4). Shocked at his suggestion, SMG3 praises Mario for the idea.
SMG3, being a supervillain, has a hefty amount of crimes committed throughout the SMG4 Bloopers Series.
SuperMarioGlitchy3 has a rivalry with SuperMarioGlitchy4, while Mario's main rival is Bowser (excluding Wario). Although they are natural rivals, they seem to get along well up until his banishment to the Internet Graveyard in SMG4: War Of The Fat Italians 2020.
SMG3 seems to have magic powers and uses sorcery on his enemies. Some of them include:
