SMG4

SMG4 is usually portrayed as either the only sane man at Peach's Castle or as a stereotypical meme-loving addict. In earlier appearances, SMG4 was constantly annoyed with most of his friends' flaws and stupid behaviors; SMG4 dislikes Mario’s stupidity, Luigi's childishness, Toad's grumpiness, Steve's randomness, Peach Toadstool’s bossiness, Fishy Boopkins’ naiveté, and Bob Bobowski’s selfishness (which is he ironically responsible for). being shown as one of the more intelligent people in the room. He and Mario would also often find themselves saving the world (or just their lives) from supervillains like SMG3 and occasionally Bowser (though the latter was usually just faced by Mario), as well as destructive gods of power like Ztar and The Monster. When SMG4 wasn't dealing with all this chaos, he could usually be found in his room, making videos or looking at memes on his computer.
Despite normally being intelligent and sensible, SMG4 still had his many quirks. For instance, he was shown being terrible at dating, and would often get picked on by Mario for it. He also takes part in and has a lot of girly hobbies (most of which he appears to be embarrassed by and tries to hide from others). This is mostly seen in the video that Mario secretly recorded of him, A Day In The Life of SMG4, in which he can be seen hopping around like a "pretty ballerina", playing with dolls, and being sad that Twilight was cancelled. In SM64 Guides: How To Get Dem Coins, he was shown to have an alter ego called the "Wallet Inspector." As this character, SMG4 would put on 19th century English gentleman attire before going around and stealing people's wallets. Also, despite usually being one of the smarter members of the cast, SMG4 still has his moments of stupidity. Going back to Mario's video, SMG4 was shown doing random stupid activities, such as screaming "pingas" on a flagpole and not being able to recognize his own reflection. The most iconic example of these moments happened in Super Mario 64 Bloopers: Who Let the Chomp Out, in which SMG4 throws a super star at the Chain Chomp, briefly making him invincible (which even Mario was baffled by, calling him stupid for it). SMG4's less intelligent moments are most prominent in Season 1, in which he is consistently shown to (almost) be as stupid and immature as Mario, with Nintendofan997 instead taking the role of the castle's straight man. This would lead to many conflicts between the two, which would eventually help in sparking the now iconic War Of The Fat Italians series. Despite these moments, however, SMG4 was still shown as the straight-man in the castle, being one of the most sane and intelligent cast members in the classic era (along with Toad, Peach, and eventually Meggy, who would arguably surpass him).
After Meggy was introduced, SMG4 became prone to a lot more goofier moments and stupid jokes. He would end up developing a meme addiction, which would become a defining part of his character. Arguably the biggest and most destructive example of this meme addiction was in 2 MILLION FAN COLLABERATION SPECIAL! (SSENMODNAR), in which SMG4 is shown capable of creating a meme bomb (which is arguably the first form of meme energy manipulation seen on the series), which he had apparently been forming for 5 whole weeks before that, and it threatened to destroy the Mushroom Kingdom. According to Peach, this wasn't even the first time he had done something like that. SMG4 (especially in older episodes) sometimes had a questionable moral compass. As mentioned previously, he would also often get into trouble with the law, committing various crimes and illegal activities, usually in attempts to get Mario his spaghetti. SMG4 has many other flaws. He could easily become overprotective of his work, sometimes refusing to hang out with his friends in favor of making bloopers. Despite usually having a brotherly relationship with his peer, Mario, the two were also prone to incessant fighting and conflicts. SMG4 can also be very easily annoyed. For instance, the stupidity and antics of people like Mario and Steve sometimes drove him crazy. He was also annoyed by obsessed fans, or generally annoying people, like Frankie, Fishy Boopkins, SMG69 (who he got so fed up with that he ended up permanently killing him by flying and throwing him into the sun, once gain showing his criminal tendencies), and initially Bob, back when he was constantly asking to be in his videos. SMG4's ignorance and naiveté can also cause him to be careless about other people's situations, making him unintentionally be a bad friend. The best example of this is in SMG4: SMG4's Origins, where it is revealed that SMG4 was virtually careless and ignorant about the mental state of the citizens of the Mushroom Kingdom, even tolerating Mario's stupidity. When he made his first video, SMG4 immediately became hooked to his newfound hobby and recorded everyone he came across, partially taming their stupidity in the process. When SMG4 realized that everyone was still stupid even though he got rid of the problem, SMG4 shrugged it off, thinking that there's nothing wrong with "a bit" of humor in everyone's lives. This is can be seen to a lesser extent in SMG4: If Mario Was In... Splatoon 3, in which he and Meggy are so tunnel-visioned on getting the stupid Mario back that they don't consider trying to befriend the normal Mario, and once again force the stablized plumber back into the bastardized, problematic shell of his true self (though, to be fair, their actions did lead to the Nintendo characters no longer being segregated by Lawyer Kong in that arc). SMG4 also somehow completely forgot about Princess Peach in the ruins of her castle and left down there for several months, then years, not even remembering until the events of SMG4: Let's Go Visit Peach!. However, he did eventually return to rescue her in SMG4: Saving Princess Peach.
SMG4 is also prone to being jealous and selfish (usually in regards to his YouTube channel). One of his biggest flaws (besides his meme addiction and carelessness) is his how worked up he can get over his videos. SMG4, in general, has always shown to take his YouTube channel way too seriously, which has caused problems numerous times in the series, and sometimes leads him to commit various morally questionable acts in the process of making them, usually due to jealousy.
Despite his flaws, SMG4 has been shown to be a brave, compassionate, thoughtful, and loyal friend, and is genuinely a good person overall who truly does care about his friends, especially Mario

SMG4 is similar to Mario
He wears a long sleeved blue shirt under white overalls, white short gloves and pale brown boots. His buttons are yellow and diamond shaped. A blue cap with a more bold and squarer emblem S on the front of his cap.
His hair is short and black and is more noticeably from the front, and has more wide upside down triangular bangs/spiky forms.
He has a slight pinkish white skintone, dark blue eyes and the pie eye shape. The model has a slight bigger nose although still roundy
He is 5'1" tall (155 cm)

SMG4 hates spaghetti, which is referenced in SMG4: Mario University. Ironically, Luke Lerdwichagul likes spaghetti.
SMG4 has the second most appearances in the series, only behind Mario.
The song that best described him the most is Justin Bieber's "Baby".
SMG4 didn't like school, and dropped out of freshmen year. He admits this might reflect badly on him to some.
His color code shares that of Stanley the Bugman from his Super Smash Bros. Melee trophy, a plumber alongside a Wario lookalike in The Super Mario Bros. Super Show! episode, Plumber's Academy and the Player 4 skin in the minigame Mario Bros. Battle in the Super Mario Advance series. However, Luke stated in Hobo Bros that it's actually just random colors he chose.
According to SMG4: Mario goes to DIDNEY WORL, SMG4's worst nightmare is his first-ever blooper, Super Mario 64 Bloopers Short: The Cake Is a Lie! But he has a picture of the video on his wall in his castle.
In Super Mario 64 Bloopers: Operation G.A.Y it was revealed that SMG4 was Chinese.
SMG4 appears in the fan-made game Super Smash Bros. Lawl (not to be confused with the web series of the same name) as a playable character.
MarioMario54321 made him a protagonist in his movie Back to the Fourth Dimension (The Rainbow Colonies).
SMG4's favorite Mario game other than Super Mario 64 is Super Fat Mario as stated in his SM64: The SMG4 QNA (400k subs :D).
He has been featured multiple times in the VS show Cartoon Fight Club. Some of SMG4 opponents have been SML Mario, Jeffy, ExplodingTNT, and TheOdd1sOut, and he has won against all of them effortlessly.
Judging by the War Of The Fat Italians series' titles, he might be of Australian-Italian nationality. However, the title could also be referencing how SMG4 is a Mario Recolor, and that Mario is Italian.
He has 2 Yoshi forms in super mario 64 bloopers: race for golden overalls (green and pink).
SMG4 holds a degree in memes, starting from SMG4: Mario University.
As revealed in SM64 Christmas 2014: The Bowser That Stole Christmas., he still believes in the Easter Bunny.
SMG4 is shown to listen to One Direction in times he's upset, namely their most popular song 'You Don't Know You're Beautiful', as shown in Super Mario 64 Bloopers: Smart(ass) Mario. Despite this, he'd mock Toad for the same thing when Toad accused him of being gay for missing Mario's moronic personality.
SMG4 is shown to drink beer, as shown in Super Mario 64 Bloopers: ÐД gℓђ when he's working on his computer and carelessly accesses the virus malware from its undebugged system, he mentions going to grab one, but wasn't able to due to Mario dumping several into his spaghetti.
SMG4 is overly obsessed with his work and may lash out at anyone who disrupts him. This attraction appears to be natural, as only mere minutes after being born, he grew an urge to create content after discovering the power of YouTube. This obsession has apparently come to the point where SMG4 made "baby videos" of his computer, much to his own dismay when he attempted to discover his past.
Ironically, even though SMG4 cannot stand Mario's stupidity and constantly insults the plumber's intelligence, SMG4 is technically the one responsible for making Mario stupid, as SMG4's Guardian Pod corrupted him beyond relief and made him the opposite of his mainstream self. Possibly meaning that everyone (including him) somehow forgot everything that happened when SMG4 showed up. Additionally, SMG4's arrival technically made Princess Peach a naggy housewife-like figure (though compared to Mario, it was due to the stress rather than SMG4's USB), Luigi apparently bisexual, and Toad a hateful person. Thus, SMG4's arrival had a mostly negative effect on the Mushroom Kingdom.
Despite this, SMG4's arrival also had a positive effect on the kingdom as Bowser eventually mellowed out and became friends with Mario (thus ending their rivalry and hatred of one another) and (possibly) created the Mario Recolors, which would later become his friends. Also, had Mario not become stupid, he would have not accidentally stumbled into other people who would later become friends with him.
He is one of the few members of the gang to be confirmed to have canonical magical powers, alongside Melony. However, this is debatable due to SMG1 claiming that avatars have extraordinary abilities.
Although he is considered a straight man to the group, he can have moments where he acts idiotic, as displayed in SMG4: The Mario Convention! and SMG4: The Day SMG4 Posted Cringe.
Despite having been depicted as the same guy prior to the Genesis Arc, SMG4 as a character is NOT Luke Lerdwichagul, but rather a being with his voice born from a USB. This is further evidenced when the opening advertisement where Luke turns into SMG4 is deleted from SMG4: If Mario Was Smart. SMG4 only sometimes represents Luke.
However, some events that have happened to Luke, such as getting hacked, are said to have happened to SMG4 as well.
Luke uses SMG4 as his persona on some non-canon videos such as Announcing My Biggest Project Yet, My whole life has been leading up to this, and mostly, his storytime videos (this may show that SMG4 is canonically speaking on behalf of Luke even when he has no idea who Luke is and simply calls him "strangely familiar" and "the unfathomable being of the great beyond" by SMG2).
SMG4 is also shown to have roughly worse video making and/or editing skills than Luke as shown in SMG4 Simulator and other videos (where he also seems to have his own channel despite shown to have Luke's channel due to a low level of views and likes).
In numerous videos, he is shown to like pineapple pizza, which is known as being the worst pizza. In SMG4: Mario waits for pizza, Even the people who he orders the pizza from thinks he has a mental disability. In Mario Joins Discord, him mentioning pineapple pizza causes a full on flame war.
SMG4 is the third character to get a redesign, with the previous ones being Meggy and Saiko. Additionally, he breaks the record for keeping his original appearance for the longest time, with a total of 11 years; with SMG3 being second (10 years, 11 months 1/2), Fishy Boopkins being third (6 years, 3 months), Bob being fourth (6 years, 1 month), Saiko being fifth (4 years) and Meggy being last place (1 year, 9–10 months).
SMG4 (alongside SMG3, Fishy Boopkins and Meggy) is one of the few characters who has been redesigned more than once.
tho technically if you count non-redesigned characters then that would mean Mario has the record of keeping his original appearance for the longest time while also appearing in videos up to the recent SMG4 videos.
Updated SMG4 Redesign, the S on his cap has static glitch effects which reference to Glitch Productions and represents that he was originally “Glitchy” because his original YouTube name is "SuperMarioGlitchy4".
His Tarot Arcana is XII - The Hanged Man.
Although his full name is technically "SuperMemeGuardian4", the shortened and mainly used form of his name "SMG4" is used on his identity card in SMG4: Mario Does His Laundry.

Superhuman Strength: SMG4 is almost as strong as Mario, being able to punch and throw people very far away, as well as being able to keep up with the plumber in combat on multiple occasions. An example of his strength can be seen at the end of the rap battle in SMG4: War Of The Fat Italians 2020, where he kicked SMG3 into the street below so hard, it resulted in a crater. However, SMG4 cannot physically lift as many things as Mario can.
Superhuman Speed: SMG4 has been showcased to have superhuman speed various times throughout the series. One notable example of this was in SM64: ṩṩἔᾗмὄḋᾗᾄʀ 8 (150k special), in which he flies SMG69 all the way to the sun in about 4 seconds, similarly to Mario in R64: Mario Simulator.
Superhuman Reflexes: In addition to his speed, SMG4 also has superhuman reflexes. This is best shown in SM64: Bad Star's Back! 300k special, in which SMG4 successfully dodges every single bullet being fired (in incredibly close range) from a machine gun by a teletubby. He also does this in Super Mario 64 Bloopers: 0% of Spaghetti, in which he and Mario dodge missiles being fired from the guy they robbed.
Superhuman Durability: Like his friends, he has survived almost all of the abuse his enemies inflict him with. An example of this being in SMG4: War Of The Fat Italians 2020, which had one the challenges being to pronounce Susan Wojcicki's last name. With each failure, SMG4 was horribly tortured, including being set on fire, crushed, beaten up, and blown to smithereens. He is also shown being able to survive a black hole in SMG4: SMG4 NEWS, and even survived a universe being thrown at him by Eldritch Zero in SMG4 Movie: REVELATIONS.
Flight: On rare occurrences, SMG4 has been shown capable of flying. One of the most notable examples of this is, once again, when the threw SM69 into the sun.
Hand-to-hand Combat: While not as good at fighting as Mario is, he has been shown on multiple occasions to be capable of holding his own in combat, such as being able to fight Mario for extended periods of time (though Mario usually wins), as well as taking out an entire army of psychotic teletubbies in the aforementioned Bad Star's Back episode.
Meme Bomb: In 2 MILLION FAN COLLABORATION SPECIAL! (SSENMODNAR), SMG4 created a gigantic ball of energy by gathering energy from internet memes (similar in concept to the Spirit Bomb technique from Dragon Ball). It had enough power to destroy the entire surrounding area of Peach's Castle, turning it into a charred wreck.
Sub-Zero Temperature Tolerance: At the end of SMG4: 3 MILLION SUB FAN COLLABORATION! and SMG4: War On Beeg SMG4, he appeared in space (which has a fatal temperature) without any protective garments.
Vacuum and Gravitational Adaption: As shown above, SMG4 shows no signs of pressure when in outer space.
Black Hole Survival: SMG4 has also been shown capable of surviving a black hole in SMG4: SMG4 NEWS.
Memory Sharing: In SMG4: TRASH FRIENDS, he shows SMG3 how he lost the USB by shooting beams from his eyes into his partner's, causing SMG3 to “remember” what happened, even though he wasn’t there at the time.

weaknesses: Mario's Life: As Mario is his Avatar, SMG4's form would be severely damaged if he dies, which almost happened if SMG1 and SMG2 had not interfered to save Mario's life from SMG0.
Ultimate Meme: In SMG4: Lord Of The Memes, he created the Ultimate Meme, and whoever has it can control the Internet.
Anti-Meme Corruption: When manipulating the power of Anti-Memes, his personality becomes overtaken by power corruption, causing him to do reckless things and sing the praises of the very God Box they were trying to stop. He'll return to normal when he stops.
Stress of Content Creation: As the owner and operator of the SMG4 YouTube channel, SMG4 gets very stressed when matters relating to the channel are on the line, leading him to irrational behavior when he's in a creative funk, which is the entire plotline of IT'S GOTTA BE PERFECT.
Sensory Overload: In SMG4: THE NEW CASTLE!!, SMG4 gets overstimulated from loud music which made him trigger his sensory overload and he kicked goths out of his room for being too loud.

SMG4 was born inside a guardian pod, after the fate of Spudnick and the Toytoy Kingdom, and it was plugged into the SMG4 Universe by Luke Lerdwichagul (SMG4's real-life counterpart). His Guardian Pod crashed in the field outside Peach's Castle and its entrance opened to release SMG4, who didn't know his identity and was confused of his surroundings. He explored the Mushroom Kingdom and unbeknownst to him, SMG4's Guardian Pod was making most of the population incredibly stupid and flanderized, also making the Kingdom's resident hero Mario an idiot with mental issues, and as a result of Mario's transformation, Princess Peach turned into a bossy and naggy ruler. During his sightseeing, SMG4 noticed a computer and taking a liking to it, decided to stay in the Kingdom to make memes out of Mario and his friends, posting them on the Internet afterwards.

He later witnessed the arrival of SMG3 in his own Guardian Pod and they became mortal enemies just by disliking each other's presence by a simple insult. After SMG4 and Mario dumped SMG4's Guardian Pod into the Dark Web, thinking he saved the world, SMG4 left the kingdom as it is, since he believed there was nothing wrong with the residents having some humor and fun (though SMG4 likely grew annoyed and tired of everyone's antics as the years flew by). Afterward, he participated in Meme School, where SMG4 became SMG3's rival in memeology. He successfully graduated from the Meme School, unaware that SMG3 became utterly jealous of him, which would lead to his hatred of the future YouTuber. Knowing only the acronym of his name, he started calling himself SuperMarioGlitchy4, which was also the name of his YouTube channel at the time. As such, he would make videos detailing what he thought could've been Mario and Luigi's origins.

The Super Meme Guardians are six individuals known as Niles, SMG0, SMG1, SMG2, SMG3, and SMG4 who act as guardians of both the Meme Life Cycle and the Avatar of their universe. Each is sent to inhabit a universe in through the "Guardian Pods" and take on the form of their avatar in any color except red.

The latter five are all natural born Meme Guardians who were born from their USBs or, in SMG0's case, originally part of the game they hailed from and have a Number to give them individuality. As for Niles, he is an artificially created Meme Guardian made by the God Box as a negative incarnation of SMG0 and thus doesn't resemble his Avatar.

The SMGs seemed to be sent to a universe in pairs: SMG1 and SMG2 were sent to the Toytoy Kingdom to protect their avatar, Spudnick, yet failed to save him from Niles; while SMG3 and SMG4 were sent to the Mushroom Kingdom to protect their avatar, Mario, but due to Niles' interference, instead became enemies and failed to carry out their purpose for many years.

As for SMG0, he was sent alone to Mage to protect his avatar, Fred, until the God Box created an Artificial Meme Guardian named "Niles" to be his partner, but this backfired when the box corrupted Niles and forced him to take over Zero's form like a parasite in order to become an eldritch virus obsessed with creating a "perfect universe".

The story of the Super Meme Guardians is central to the Cosmology Saga, as it follows their origins, the Avatars, and their long unseen conflict with the virus known as "Eldritch SMG0" and the mysterious entity existing out in the Great Beyond known as the God Box.

He is Mario's guardian and closest ally (Rival in the War of the Fat Italians series), the de facto leader of his gang, and SMG3's former nemesis. Very passionate and protective of his work, he seems to play the sane man who is often annoyed or shocked by Mario's idiocy, as well as the insanity of the world around him. Despite this, Mario and SMG4 are the two that began their group of friends that have grown over the years to include many different characters who have joined the duo in going on many zany adventures, and fighting great enemies in story arcs.

During the SMG4 Cosmology Lore, SMG4 began to wonder about his origins and following the invasion of the virus called "Zero" that sought after Mario, he began to unravel the truth behind his past and his purpose as a Super Meme Guardian. Unfortunately, following this, he was stuck fighting for his channel's existence against Nintendo in The Lawsuit Arc that temporarily resulted in the end of his gang, until Mario managed to undo the damage, with SMG4 being allowed to keep his channel on the condition that he use a original design moving forward, and he deeply thanked Mario for saving everything and everyone.

Following the events of The Lawsuit Arc, SMG4 began to realize that SMG3 was surprisingly getting more popularity than him online due to his streams and collaborations. This caused SMG4 to become envious of his partner and ultimately caused him to seek the "perfect video" to make his channel the best it could be resulting in him slowly becoming unstable due to repeated failure and lashing that anguish out on his own friends in a fit of rage as he locked himself in his room. This eventually turned to true madness as a consequence on SMG4: MAR10 DAY, where he attacked the guests and unintentionally ruined the party, before returning to his room. Shortly after returning, he orders a mysterious keyboard from an unknown entity that corrupted him by a strange, eldritch entity substance. After getting possessed, SMG4 began a 100-hour livestream countdown where he slowly becomes more insane than he already was from making his perfect video with many unsatisfied attempts as well as him becoming more and more corrupted from typing from the keyboard.

After the clock reaches zero during the "........Announcement??????" video, Meggy and SMG3 entered the room to find that SMG4's condition has considerably worsened due to the entity's influence that causes him to repeat chanting that "IT'S GOTTA BE PERFECT" and over in an unnatural voice, where his psychotic aura begins manifesting eldritch symbols.

The ultimate culmination of SMG4's insanity and efforts to create his ultimate video was him made Peach's Castle being overtaken by a strange, eldritch substance that ultimately destroyed the castle but did manage to help SMG4 realize that everyone would still enjoy his content regardless of whether it was "perfect" or not, including from SMG3 who officially became part of the gang due to his involvement.

Now with his resolve clear once more, SMG4 sought to amend for his mistakes by building a new castle where he would be responsible for his own life from now on instead of having to piggyback off other's ideas/help. From there, he used his life savings to purchase an abandoned carnival called "The Showgrounds" and, over the course of several months, finally succeeding in creating The SMG4 Castle where he could begin a new era of videos and stories with the gang.

In the Remastered64 series, despite being redesigned, his old Mario Recolor model is still used for the purpose of remaking an old video in the past to match the events of said chosen video being remastered. Along providing voice lines from Luke Lerdwichagul as well like in the modern videos. These videos are just remakes of old videos, and fit into the canon when the original one took place.

In MEME HUNTERS and SMG4 and the Meme Factory, he starts to build his own factory by which, using Leggies, he creates more memes.

If you've ever wondered what would happen if Nintendo took a wild ride through the depths of internet culture and emerged on a meme-fuelled trip in a World of Weirdness where Hilarity Ensues rule supreme, then SMG4 is exactly what you're in for. Join SMG4, Mario, Luigi, Meggy and all their friends in the many wacky adventures as they dive into memes and deal with their own personal struggles. But while the fun and memes roll in, the absurdity might just spiral into dire consequences, threatening to change their lives permanently.

No matter how terrible things get, though, the gang always finds a way out—sometimes by the skin of their teeth, and other times by fully embracing the chaos in the most meme-filled way possible. Along the way through the deadliest challenges, the crew's bond grows stronger like never before over time as they delve deeper into the origins of their own history to fight their everlasting scars from the threats they encounter, as well as learning the values of their purposes, overcoming the harsh realities of life itself, and fully embracing the unknown.

Mario is SMG4's best friend and his avatar; however, the two are prone to incessant fighting, even over minor issues. SMG4 frequently gets fed up with Mario's antics and stupidity, often insulting the plumber with homophobic slurs or calling him a r*****/dumbass. Mario also has problems with Glitchy; for example, he finds SMG4's SM64 bloopers unnecessary and stupid (feeling especially angered and insulted when SMG4 claimed making videos was more important than having fun with him), oblivious to the fact that his existence and well-being hinges on the production of these videos. Mario and SMG4's hostility towards each other has practically been monetized with the annual War of the Fat Italians.
In Seasons 1–2, Mario and SMG4 almost never considered each other friends, and in fact have shown signs of hating each other. SMG4 in particular found most of Mario's antics extremely annoying, and he often made it clear he thinks of Mario as a terrible friend and wanted the plumber out of his life. Thus, when some characters antagonized Mario, SMG4 would often take the antagonist's side. Not helping is the fact that SMG4 in his debut was apparently racist towards Italians (Mario was born from an Italian mother). This hatred of Mario was taken to the extreme in "The Elevator", where after Mario and Luigi seemingly died at the end, the YouTuber instead partied around the Bros. graves and made fun of them. However, it is likely that SMG4 mellowed out and began finally accepting Mario for who he was and thus, truly began enjoying his company, restoring their friendship.
The two first met not long before the events of the the first episode. When SMG4 first saw Mario, he asked him to do something stupid for his video, allowing him to tame the Italian. The two would go on to make "the stupidest sh** ever". SMG4 only met Mario after the latter got corrupted by his "ship", thus he never knew Mario's original personality.
In SMG4 Deleted, SMG4 was sent to the Internet Graveyard after SMG3 prevented to two from ever meeting. Mario was saddened by these events and realized that he was now alone but later was glad that the latter was still alive.
While SMG4 is at times annoyed by Mario's stupidity, he is solely at fault for the way he behaves. As revealed when he first arrived in the Mushroom Kingdom, his Guardian Pod zapped Mario and made him act like the stupid fool he is today.
Mario and SMG4 seem to have a love-hate relationship, but they remain friends for several reasons. SMG4 has been shown to care deeply about Mario, and after a particularly tough ordeal will ask the latter for forgiveness. Mario will also get sappy during these scenes, but his emotions have often been used or discarded for comic relief. SMG4 has also become more protective of Mario after learning that he is one of Mario's guardians (the other being SMG3) and presumably values Mario's safety more than ever after learning that if he dies then everything dies. In short, Mario and SMG4 are perfectly fine with one-another when something crazy isn't happening.
However, this bond of theirs would be strained when SMG4 would work on his perfect video for weeks, isolating himself away from everyone, his friends and Mario included. This would get even worse on MAR10 Day when the router was accidentally knocked by Wario in the chaos and caused SMG4 to be enraged to the point of lashing out at everyone and blamed them for disconnecting the internet when he burst out of his door. After SMG4 attacked and kicked everyone out, he unintentionally ruined Mario’s special day that he is unaware of in the process even though Mario just wanted him to join the celebration. When he lashed out at him about that, he hurts his friend's feelings when he was going to give him a "Best Friend award", but he chose to care about his video rather than him.
When SMG4 announces his retirement as well as the show’s conclusion, Mario is the only member of the Glitchy Gang who struggles to accept it. After going on a journey through the five stages of grief with past SMG4, he finally comes to terms with SMG4 for retiring and ending the show before they go their separate ways.
Status: Best Friend

While he sometimes called out on Mario for abusing Luigi, SMG4 rarely interacts with him, often hanging around with Mario instead. However, on the rare occasions that they do, SMG4 often treats Luigi in the same condescending, abusive manner that most others do. However, despite that, he seems to care for him, as the latter tried to furiously kill Mario with a chainsaw after that one killed Luigi in Luigi Wants to Build a Snowman., and stated in SM64: Meet the Luigi that he feels bad about him being a character always beaten up and forgotten. There would be times that SMG4 would mistreat Luigi however, as shown in The Swap, where he said that Luigi was "adopted and nobody likes him", while stuck in Mario's body.

Status: Friend

SMG4 doesn't care too much for Toad, seeing him as grumpy. Likewise, Toad finds SMG4 a nuisance. However, the two are always in close proximity and often go on adventures together, usually accompanied by Mario.

Status: Neutral

Bowser sees SMG4 as a friend, despite him and Mario destroying his home in SMG4: Mario waits for pizza.

Status: Friendly

They see each other a lot, though no one is quite sure if they are friends or not. SMG4 constantly insults him, calling him an "annoying piece of green sh!t", and showing that he hates Boopkins for some reason. As of 2017, he stopped hating him and became his friend.
He sided against Fishy Boopkins during the Food War.

Status: Friend

SMG4 and Meggy don't interact a lot, though, in many videos, there are stupid things in the background that are not easily found. Some show TV screens of Meggy and SMG4 1v1’ing with Splattershots. Overall, their relationship is neutral, for most of the time. However, they have some rivalry in War of the Fat Italians 2017, due to Meggy supporting Mario. In addition, he sided against her during the Food War.

Status: Close Friend

They were seen playing together at the end of SMG4: Mario The Ultimate Gamer and in SMG4: The Intruder.... Later in SMG4: The Mario Carnival, SMG4 requests to help her to win tickets for the Eggman Football, and is seen carrying an overbearing amount later. SMG4 and Tari are good friends, and it's clear that he cares for her.
He sided against her during the Food War.
In SMG4: MAR10 D4Y SMG4 blocked Tari on Discord while trying to get him out of his room.

Status: Friend

Before the The Waluigi Arc, Waluigi's relationship with SMG4 seems to have relatively neutral, varying from blooper to blooper. Even throughout the Waluigi Arc, Waluigi didn't pay much heed to SMG4 until SMG4: War Of The Fat Italians 2018, where he tried to add SMG4 to his "collection" and forced him to partake in series of challenges alongside Mario, with the threat of being stuck in The Rejection Dimension forever if they didn't comply. SMG4 now heavily despised Waluigi for turning his friends into zombies and called him an "ass".

Status: Neutral

SMG4 has developed a hatred towards SMG3 after finding out that he's been stealing his videos. Their relationship has become even more violent and negative over time. However, there would be times that they would work together, as shown in SM64 Bloopers: SnowTrapped where they tried to get along after being snowed in an igloo, but they eventually go crazy and r******* from hunger. Oddly, SMG3 fought Mario more times than SMG4.
SMG4 had gone to the point where he immediately assumes that SMG3 is up to no good when SMG3 actually becomes popular and destroys his production studio as a result. Naturally, this led to SMG3 to coming up with a revenge plot to destroy SMG4, which ultimately fails.
After SMG4 finds out that SMG3 became the ruler of the Internet Graveyard, he decides that it's better than having him stay in the Mushroom Kingdom. Overtime, SMG4 began to trust SMG3 to the point where he asks him for help (only when he's desperate, of course). As of The SMG4 Movie: 10 Year Anniversary Special, his hatred for SMG3 seems to have died down.
He later ends up encountering SMG3 in SMG4: Mario and The Backrooms, where he, Mario, and SMG3 were all abducted via toilet. They end up teaming up due to their situation with Zero. When stuck in Zero's mind torture and SMG1 and SMG2 appear to help them, they are instructed to hold hands to use their Guardian powers. Both him and SMG3 are initially disgusted by this, but lighten up when they see that their powers work.
By the end of Genesis Arc, they seem to be able to tolerate each other more, excited about learning more about their meme abilities. By this point, SMG4 is on good enough terms with SMG3 that he'll willingly invite him over for the holidays even if the latter is likely to be a jerk to everyone.
SMG3 decided it was time for him to move out of the Internet Graveyard to build his own coffee shop/evil lair, "III's Coffee N' Bombs." next to the castle, moving in closer to his friends. Since then, he now changes his ways and becomes part of the crew as they go on their adventures and he has truly declared to bury the hatchet, thus he finally abandons his old evil goals of making SMG4's life miserable.

Status: Close Friend

Like many other characters, SMG4 is constantly annoyed by Bob and his antics. In SMG4: War of the Fat Italians 2017, when tasked with making Bob popular, he turned Bob into a cleaning product, which had him clean up various stains and Wario's ass, showing that he wanted to abuse him. As of 2018, SMG4 grew more accepting of him, but during SMG4: The Mario Purge (Halloween 2018), he refused to let him inside the castle to avoid the risk of letting the Teletubbies in.
When The Rapper Bob Arc started, he was neutral with his fame and thought it was good for him to be happy, but that changed during SMG4: Mario and The Diss Track. During Ultimate Diss Track, Bob called SMG4 an unfunny disgrace. SMG4 had been mad at Bob, but still shows compassion for him as a friend, specifically when Bob decides to change his ways.

Status: Friend

Initially, SMG4 saw the pair as two crazy hobos constantly chasing after him, but after it's revealed that they were trying to warn SMG4 about the day of reckoning and they help save him, Mario, and SMG3, he becomes thankful for them for helping, mentioning that he doesn't even know their names, prompting them to announce that they're SMG1 and SMG2, shocking SMG4 along with everyone else. They tell him to look for their Guardian Pod before sealing Zero away with SMG3's Guardian Pod, accidentally sealing themselves away as well.
After the whole incident, SMG4 couldn't stop thinking about the two and what they said, leading him to go on a search for the origins of the SMGs, especially since he knew next to nothing about himself. He, along with Mario, eventually discover how SMG0 destroyed SMG1 and SMG2's old universe by killing their avatar, Spudnick, horrifying them.
They eventually end up reuniting when SMG0 pulls him, Mario, and SMG3 into a mind torture simulation inside SMG3's USB, and SMG4 is more than happy to see them again. They educate SMG4 and SMG3 about meme energy and teach them how to manipulate the energy. They later escape the Guardian Pod and team up to stop SMG0 from using Mario for his plans.
After they succeeded in stopping SMG0, SMG1 and SMG2 thank SMG4 and SMG3 for their help and reveals that their family name stands for Super Meme Guardian (not "SuperMarioGlitchy") before saying goodbye, shocking Super Meme Guardians 4 and 3.
Overall, SMG4 seems to respect the two for being his and SMG3's predecessors and helping them on multiple occasions.

Status: Allies

SMG4 first met "SMG0" during the 10 Year Anniversary incident, where he, Mario, SMG3, X and FM were kidnapped by the corrupted memes and brought to the Dark Web where he witnessed a monster attempt to destroy Mario, only for SMG1 and SMG2, along with the gang, to intervene.
Realizing that Eldritch Zero had a connection to his origins, SMG4 became obsessed with finding answers onto who and what Eldritch Zero was, going crazy in the process until Mario snapped him out of it. SMG4 realized he had to take his time finding answers and decided to look for SMG1 and SMG2's USB.
Upon discovering the USB, SMG4 and Mario saw the memories of SMG1 and SMG2, where he learned that Zero was an SMG like him and the others and that he for some reason killed Spudnick, the previous avatar. This made SMG4 realize how truly dangerous "SMG0" was and that Mario was his target, making it clear that he had to protect his avatar from the virus.
Upon Zero's return, SMG4 became worried for Mario's safety and had him hidden while Swag and Chris tried to destroy SMG0's USB. However, Niles (after possessing Axol) managed to drag him, Mario and SMG3 in the Backrooms before trapping them in SMG3's Guardian Pod. After escaping with the help of SMG1 and SMG2, SMG4 witnessed Niles' plan: convert Mario into his avatar, horrifying SMG4.
After a long battle, Eldritch SMG0 was defeated by Melony to the relief of SMG4 that Zero was gone. However, six months later, after following Melony in the God Box, he wakes up after crashing to find a mysterious blue, one-eyed person having tended to his, Mario and SMG3's wounds. When the stranger introduces himself as SMG0, SMG4 is shocked and wonders if he is the same "SMG0" they fought back home, causing SMG0 to realize Niles' actions and explains his backstory.
Learning the truth behind SMG0, SMG4 postulates that Eldritch Ax0l's death caused the real SMG0 to be separated from the evil of Eldritch SMG0: Niles. However, he is horrified when he realizes Niles' reason for possessing Melony and getting inside the God Box: he wants to refuse with SMG0 to become Eldritch SMG0 again and continue his plans. He tells SMG0 to hide but is too late as Melony (possessed by Niles) busts through the ceiling and successfully merges with SMG0 to become a virus again.
After the God Box's destruction, it is unknown how SMG4 felt about SMG0 after learning the truth. However, given that he prioritized getting Melony out of the God Box without even considering saving SMG0 at the same time, its possible that SMG4 didn't care enough about him to bother wanting to save him. This could be further emphasized by how none of the gang ever learned the truth about Niles being their true enemy as Tari thought that the Demonic Goop was the work of "SMG0" again, proving that SMG4 never bothered to explain it to anyone and thought nothing of him afterwards.

Status: Neutral

SMG4 learned about Niles when he, alongside Mario and SMG3, met the real SMG0 inside of the God Box when searching for Melony.
SMG0 explained that Niles was his partner, an artificial meme guardian that the God Box created for SMG0 to save his universe, only for Niles to betray him and kill their avatar, Fred and then possess SMG0 to become Eldritch SMG0. Hearing this, SMG4 finally realized the reason behind Eldritch SMG0's actions and that all of his feelings and misgivings towards SMG0 were wrong the entire time and saw Niles as the true threat, as well as the one who was responsible for killing Fred, Spudnick and (indirectly) Axol.
However, SMG4 then realized why Niles needed to possess Melony to get into the God Box: to find SMG0 and possess him again to finish what he started and was too late in hiding SMG0 when Niles ambushed them and tried to take SMG0 by force while also attacking Mario and SMG3. Trying to stop him and demanding that he release Melony, SMG4 was threatened at sword-point by Niles and after Melony was freed, was horrified to see Niles holding SMG0 captive, shocked upon seeing who the true essence of Eldritch Ax0l was.
Despite learning that Niles was the true evil that they fought, SMG4 never bothered to explain to SMG1, SMG2 and the rest of the gang that he was impersonating SMG0 the entire time since Tari thought that SMG0 was always their enemy given how she asked if he was the one responsible for the creep consuming Peach's Castle. Regardless, it's assumed that SMG4 continues to bitterly hates Niles to this day for being the one who "killed" Axol.
