SuperMarioGlitchy3, more commonly abbreviated as SMG3, is SMG4's evil doppelgänger and a major antagonist of the SMG4 series. He initially served as one of the two main antagonists of the earlier seasons of the series (alongside Bowser), the main antagonist of the middle seasons, and a recurring antagonist of the later seasons. He's SMG4's evil doppelganger who was first discovered trying to copy SMG4's videos, and now tries to kill him. He (and Wario) are the people responsible for turning Waluigi back to normal at the end of WOTFI 2018. After that, he retired from villainy to start a therapy television series called Dr. SMG3 which was seen during The Waluigi Arc. It lasted until A Day In The Life Of Everyone where his therapy show was cancelled, causing him to go back to his villainous ways.
He lives in a colossal fortress located in an unknown realm, and his best friend is Nintendofan996 (Nintendofan997's doppelganger). He also earned a psychiatric degree before the events of SMG4 VS SMG3. He also won a Mushroom Kingdom award for most outstanding citizen during the events of SMG4: Mario's Late!, contradicting Baldi's belief. Much like Toad, Bowser, Wario and Waluigi, he did not get enough screen time in Season 9 however he appeared the least in Season 7.
Being the arch-rival to SMG4, SMG3 is slightly the opposite of SMG4 in terms of appearance. His shirt and cap are of a darker blue color, while his overalls are black, also retaining gold buttons. His Garry's Mod model shows a skull emblem on his cap which often isn't visible on his current Super Mario 64 model.
In more recent episodes, starting with SMG4: Mario Gladiators. His GMOD model, now a recolored model of Mario from 2017 game Super Mario Odyssey, has more detail to his outfit, with more vibrant colors, alongside a denim texture and lacing on his overalls.
In his first appearances, SMG3 is prone to be a very arrogant, selfish, stubborn, vain and merciless bad guy who appears to be an incompetent villain, using useless tricks to defeat his foes, with very little success. In his later appearances, he begins to show a much darker personality, now that he was promoted to be a main antagonist. Despite appearing to be more evil, he continues his incompetent acts and will usually try to do something unusual to save himself, much of the time hurting him in the process, yet protecting or enabling him to escape successfully.
Like SMG4, SMG3 seems to be a showoff on Bowser whenever they bother on something they think they are better with. He always seems to want to do everything to get SMG4 and killing everyone in his path that defends him.
In SMG3's mind, he's supposed to be the evilest person in the world, not Waluigi, hence why he helped Wario and the rest of the heroes during The Waluigi Arc.
However, aside from his evil traits and stints as the villain, SMG3 has proven he can be as much as a bumbling, goofy dork as his rival, and is shown having found doing normal hobbies, including eating chicken, taking long naps, reading JB mags, even starting a club for bad guys. For some reason, he even enjoys partying. Not to mention that he is also bratty and a crybaby.
Being the main antagonist in his debut episode, SMG3 had flagrantly plagiarized SMG4's previous bloopers, but was eventually caught by SMG4 and Mario. When SMG3 escaped, MCGustavo threw a paper at him and got a paper cut. In his initial appearance, he appears to be a much more incompetent villain.
Once again, he is an antagonist, as he battles with Mario but Mario's stupidity and idiotic personality gets him defeated.
As a major 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.
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 was 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 was 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 Luigi'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 was flung out of it into the water.
As the secondary antagonist, SMG3 helps a crazed, angry Roprinplup14 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 kills them. He manages to escape from Roprinplup14's extreme up-to-eleven terror, while he gets arrested by the cops, 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 was immortal so instead, they tied it to a boat and had Good Star watch over it.
He and Bowser are teamed up as the 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 Negative SMG3 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 was 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 was stealing a lollipop from Stacy's baby (which was actually a The Police), 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 was responsible for the appearance of a lot of evil pipes in that same garden. However, the real commander of the invasion was 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 wasn'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 on 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 is seen trying to do an evil plan, but Bowser was doing retarded stuff. Shortly after, SMG3 was 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 was 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. Mario gets in (thanks to Old Man Hobo's rocket launcher) and takes both SMG3 and SMG4 back home.
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 which 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 was 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 was a different take on SMG3 because he was never a king in a kingdom before.
Due to his acts in the previous video, he was 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 was one of the contestants, though he was only seen in 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 was 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 was 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 Dreamland's food supply out of pure evil intentions (and because he was 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. The session works, and Wario and Waluigi reconcile, but SMG3 is unenthusiastic about the situation 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 fighting with him.
Once again as 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 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 was revealed to have kidnapped Bowser for over a month to be a guest on the show. His show was also eventually canceled, forcing SMG3 to revert back to his evil ways.
Mario finds SMG3 digging a tunnel to Area 51. It was 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 was foiled by SMG4, Mario and Saiko Bichitaru and he was 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 was 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.
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 and in SMG4: Mario vs IT 🤡
Lack of Motivation
Unlike some villain characters who have a reason for wanting to kill Mario and company (like Roprinplup14 when Mario ruined his party) or taking over the world, SMG3 appears to have no reason at all for all the terrible things that he does or tries to do, mostly wanting to ruin SMG4's reputation and kill him. When he explains his reasons, he simply says "Because I want to!" In Mad Mario, he simply wants to take away all of the Mushroom Kingdom's internet and create a site where people have to watch his videos, implying that he wanted to become just as famous and popular as his rival. Additionally, the probable reason for why he became a supervillain was out of anger at SMG4 for stealing his chance at fame. However, he also commits crimes that aren't even related to SMG4, an example being SMG4: If Mario Was In... Kirby Star Allies, where he stole Dream Land's food supply because he was poor and couldn't afford actual food, despite the fact that he's seen living in a house.
SMG3, being a supervillian, 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.
SMG3 seems to have magic powers and uses sorcery on his enemies. Some of them include:
