SMG3 (short for SuperMarioGlitchy3) is SMG4's arch-rival and the recurring antagonist in SuperMarioGlitchy4's Super Mario 64 Bloopers. 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.
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!, contradictory to Baldi's belief.
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.
At his first appearances, SMG3 is prone to be very arrogant, selfish, stubborn, vain and merciless bad guy who appears to be a 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 Main Antagonist. Despite appearing to be even 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.
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.
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 and found doing normal hobbies, including eating chicken, taking long naps, reading JB mags, even starting a club for bad guys. He even enjoys partying.
SuperMarioGlitchy3 first appeared in SMG4 vs SMG3 as the main antagonist. In that video he had flagrantly plagiarized SMG4's previous bloopers, but was eventually caught by SMG4 and Mario. When SuperMarioGlitchy3 escaped, MejiaCantilloGustavo threw a paper at him and got a paper cut. In his initial appearance he appears to be a much more incompetent villain.
SMG3 is again a major antagonist in Crystal Funhouse, only to appear without Bowser. He traps SMG4 and the others in a nightmare world, with there known enemies haunting them. He ends up getting caught and beaten up in the bathroom, reading Justin Bieber magazines.
In Hunt for the Hero's Clothes, he appears to take over the world and battle Mario, but seeing him being naked, he decides to fight him next time. He later appears in the episode, sitting on a toilet as a cameo appearance.
In Bowser and the Nightmare Stone, Bowser and SMG3 use their nightmare stone to abuse the good guys and trap them in a nightmare world. But in the end, an unknown warrior appears and damages the stone.
In SMG3's Plan to Destroy SMG4 'Cause He Felt Like It, he is the main antagonist. He conducts a master plan to destroy SMG4 by bringing all the enemies back to life (using the Nightmare Stone, somehow) to destroy SMG4, but fails.
He made another appearance in The Imposter to hire a teleporting, shapeshifting hitman to destroy SMG4 and the others, but again fails due to the hitman's incidental death.
In The Monster, he is once again the main antagonist. He revives The Monster/Baby Mario (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.
In A Lost Luigi, he appears as one of the persons to whom Luigi is asking for the way to Mario's House, to which he got kicked out by Mario, but SMG3 doesn't take care of him, like if he wasn't there.
In Two Evil Friends., he is officially appointed the new main antagonist role of the bloopers by Bowser's boss, making Bowser the secondary antagonist and his partner. They both do evil stuff, but only manage to do little things. When they think of a plan, he and Bowser decide to steal the Princess as its original. They both try to kidnap Peach, but when she asks for the shampoo (unaware that it was SMG3 and Bowser instead of Mario), she finds both when Mario comes in and kicks them out of the castle.
In The Mystery of the Missing White and Blue, he is the secondary antagonist, 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.
In Super Happy Magical Fun Fun Island, he is the main antagonist yet again. 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 drowns so he gets trapped along with the other gang when they are about to die.
He isn't ready to give up yet though. He then uses a robo 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 reaction, he throws Peach at his screen, causing him to fall. He finally surrenders and accepts fate, but SMG4 realizes the robot is indestructible, so they all go in SMG3's robo suit and the island explodes while getting flung out of it into the water.
In Retarded64: Retard Karts 101, he got squished in a street by Mario, who was riding his kart without taking care of people walking in the city.
His next appearance was Birthday Freakout., this time the secondary antagonist, helping a crazed, angry Enzo assassinate Mario for eternity after he ruins his birthday party (thanks to Steve being "invited" to the first party). But however, SMG3 goes on SMG4 and Mario's side while Enzo counts while playing hide and seek, because if he finds them he kills them. He manages to escape from Enzo's extreme up-to-eleven terror, while he gets arrested by the cops, pushing his rage up twice.
Ever since then, SMG3 has made small appearances, and more before (including in 2 Hands 1 Job).
SMG3 returned as the catalyst villain in Bad Stars, having created a "bad star" to destroy the Mushroom Kingdom, but it ends up escaping to Delfino Plaza thanks to merging with a Toad. Since it attacks Mario, Bowser, SMG4, and SMG3, they plan to make a good star to defeat the bad star (this time Bowser uses an Old Man to create the Good Star). But since the Bad Star is immortal, they tie it on a boat to get it away from them.
In Spells n' Wiztards, 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 try to escape, they overhear 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, this is so 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 in Sonic the Derphog: The Evilness of Eggman (?) in which he is the leader of a group of bad guys. Ivo Robotnik tries to join it, but SMG3 doesn't want him in his club, so Eggman has to do evil stuff, but SMG3 stills doesn't let him in the club ('cause all he just did was stealing a lollipop from Stacy's baby (which was actually a Policeman), and destroy someone's lunch). Eggman then makes a demon (Perfect Chaos) and SMG3 says that is the most evilest thing in the world and then he runs away in panic because the demon is going to kill everyone (but Toadwardo destroys it).
In Retarded64: Freddy's Spaghettiria, he asks Mario where to find "Russian pet dolphins".
In Problematic Pipe Problems, Mario tried to kill him by putting him (with Bowser) in the lake of the garden of Peach's Castle, thinking he was responsible of the appearance of a lot of evil pipes in that same garden. But the real commander of the invasion was in fact the King Pipe, who led a revolt against Mario for incompetent plumbing.
In SM64: The Retardness of 2014, SMG3 appears at Mario and SMG4's talking room as a cameo, and complains about how he wasn't invited to the party. SMG4 tells him that he only appeared in Bad Stars, upsetting him.
In The Idea Block., he appears amazed to see SMG4's fans being angry at SMG4 because he got an idea block.
In M. K. Nature Channel, he's briefly seen on a harmchair, watching Mario naked doing pole dance on a tree.
In SM64 Bloopers: Shoot to the Observatory in the Sky, 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 starts mashing the keyboard, blocking a wormhole. Bowser smugly notes this works every time.
In Meet the Bowser, 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.
In SnowTrapped, 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. Soon Mario gets in (thanks to Old Gramps 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 a 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, oblivious that Bowser also wants to steal the footage.
Mario and SMG4 manages to reach his lair and confronts him, with the footage have 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 has succeeded. 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. This episode is so far the only one which truly showed SMG3 being a threatening villain.
In SMG4: Welcome To The Kushroom Mingdom, he is again the main antagonist (have to note this, iz important). 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 for whatever reason he did not create a replica of Mario and Luigi, 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 Bowsur 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.
SMG3 also appears in Ssenmodnar 12 - STOLEN SPAGHETTI EDITION where he's walking down an alleyway and 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 also makes a cameo in Stupid Paper Mario.
In The Mario Channel: MARIO'S CHALLENGE, he is shown jumping from mushroom to mushroom when one falls and starts collapsing into the lava. SMG3 decides to jump to a Mushroom near the exit, he just about makes it but Bowser hops along and knocks him into the lava.
In SMG4: Mario Gladiators, the main antagonist yet again. SMG3 kidnaps everyone and pits them against each other for a 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 just throws a rock at the latter, causing him to get angry and engage Mario in a fight. Bob then showed up and randomly pressed buttons in his throne, opening a door that revealed the defeated participants, who angrily burned SMG3 and hung him in the entrance to Peach's Castle. SMG3 then says "F*CK".
In If Mario was in... Kirby Star Allies, 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 JK and kick him off the Halberd, defeating him. He's a silly little idiot.
In SMG4: The Mario Hustle, SMG3 is visited by Saiko, who is attempting to sell rocks to him. At first he refuses, but when Saiko threatens him, he 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.
In SMG4: War Of The Fat Italians 2018, SMG3 appears 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 go to play video games.
In Mario's Late! SMG3 is awarded The Mushroom Kingdom Award for saving the world from Waluigi. SMG3 taunts SMG4, who gets angry and starts fighting with him.
In SMG4: Mad Mario, he is the main antagonist. With the help from Wario and Waluigi, he captures Mario. Now having employed Wario and Waluigi as his minions, with their aid he steals all the internet in the Mushroom Kingdom. This causes an apocalypse with everyone understandably loosing their sanity. With the joint effort of SMG4, Mario, Luigi, Toad and the Wild Child's (Meggy, Tari and Saiko) he is defeated.
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:
