He is the legal guardian of Jeffy, the fiance of his girlfriend, Rosalina (as of August 12, 2017), and ex-husband of Peach.
Mario's appearance is the same from the games. He has a short build with a well physique and a round nose. He wears a red cap with an "M" on it. He has blue eyes, a red shirt, blue overalls with two yellow buttons, white gloves, and brown shoes along with brown hair and a darker mustache and eyebrows. The only difference he has between the SML and game variations of him is that he is mostly bald instead of having a full head of hair.
Mario was a man born in Venice, Italy, who then moved to Brooklyn to start a plumbing business with his brother Luigi (who was born in Naples), later on, he started an adventure. He was originally called Jumpman and first appeared in the Donkey Kong series, until he found the Mushroom Kingdom and married Peach. Mario always had to save Peach and her kingdom from Bowser, usually with his brother Luigi, until the SML era. At some point, he bought a house and invited his friends to live with him.
Mario is a down-to-earth sane man, one of the few SML characters who is made for the regular feel rather than solely for laughs. Mario is a responsible man, owning a house while supporting Black Yoshi, Shrek, Mama Luigi (before he died), Woody, Tony the Tiger, Mr. Pig, Toad, and temporarily the Angry Birds before kicking them out.
He is rather clever, being able to trick Bowser into letting him and his family move in with him. He also outsmarted him by finding out he put poison into his food.
Out of all the characters, is the smartest and least retarded character along with Chef Pee Pee, Cody and the Brooklyn Guy. He's the generic guy stuck in a house of morons and weirdos.
Mario is also sometimes a bit of a pushover, letting people like Black Yoshi and Shrek live with him when they drive him crazy, even though he could kick them out. In Mario's Family Moves Out!, he admits that he doesn't know why Shrek, Black Yoshi, Tony, Woody, and Toad live with him.
Mario often gets angry and frustrated when dealing with the stupidity of those around him. Ever since Jeffy was introduced, he became more irritable and a bit more of a jerk.
He stands as the voice of reason in the house and often acts as a foil to people like Bowser, Mama Luigi, Black Yoshi and Tony.
Mario has been shown to be somewhat shallow, such as in Mario's Beautiful Date!, where not only tries to kill himself due to having no one to love but also constantly asking if the woman was attractive as his main concern, not thanking Bowser or Black Yoshi or the Brooklyn Guy for getting him a "girl".
Mario's main flaw is that he's a creeper and a stalker towards women, as he kept whining and stalking Peach, during his loneliness. He even slept with Peach's thong. When he met Rosalina (after Peach got a restraining order against him), Mario's lonely status ended once and for all.
Another flaw of Mario's is that he tends to get jealous over Rosalina paying attention to someone other than him such as D-Money Senior, Jeffy, Shrek, or her turtle.
Mario also complains about little things, such as having to climb up stairs in The Warp Pipe!. He is also shown to be ungrateful sometimes. He can also be tempted into doing something he shouldn't, as he killed Rosalina's pet turtle, who she adored.
Mario is usually nice and generous, however, he begins to develop an often cruel and inconsiderate side in 2016. He tried to abandon Jeffy at the park in Where's Jeffy? and in Mario's Turtle Problem! where he brutally kills Peewee by setting him on fire and bashing him into a wall, causing him to crumble to bits.
Mario is also revealed to have a cowardly side, as in Jeffy's New Toy!, he becomes extremely frightened by the electricity going out, whimpering and insisting that he needed a flashlight. In The Secret Door!, he tries to avoid going in the door after Jeffy screamed going inside of it.
Mario is shown to be a both good and bad father to Jeffy. He truly gets concerned about Jeffy's wellbeing, teaches Jeffy lessons when Jeffy acts misbehaved, and cannot live without Jeffy. However, Mario sometimes scolds Jeffy for minor things, can be hypocritical towards Jeffy, and wanted Jeffy dead prior to Jeffy's Parents!.
Despite his flaws, is shown to have a kind heart, as he agreed to adopt Jeffy because he felt sorry for him, and he let Jeffy play his cat piano to his heart's content after that.
Forms and Variations
Fire Mario is a transformation of Mario when using the Fire Flower. His appearance and powers stay consistent to the games. He used it in Mario's Turtle Problem! to burn Pee-wee to death.
Wing Mario is a transformation of Mario when using the Wing Cap. He used it in the MLSDA episode Mama Luigi
Wing Mario is also used in SuperMarioLogan's earliest videos.
Stupid Mario takes on an appearance similar to Jeffy, and only appears in Jeffy's Cat Piano Problem! A certain group of fans gave this form the nickname "Meffy". He takes on this form when Jeffy is controlling his brain to do whatever Jeffy wants. In Jeffy's Cat Piano Problem, Jeffy uses this ability to get his cat piano back.
Mario likes Black Yoshi, but he, however, gets annoyed with Black Yoshi's gangster and freeloading ways and tries to get him to be responsible and a law abiding member of society, but Black Yoshi doesn't listen to him. Black Yoshi still cares about Mario and he brought him and Rosalina together.
When Mario first met Rosalina, he started to fall madly in love with her. He was also willing to find Rosalina's star, Luna for her. Since then, he has become loyal and devoted to Rosalina and started to love her even more. However, Mario can get annoyed with Rosalina being an airhead and gets irritated by Rosalina's constant taking about the stars. He usually gets frustrated with Rosalina about Jeffy. He also gets jealous when Rosalina pays attention to someone other than him. In The Ring!, Mario was planning on proposing to her, but failed because Jeffy desroyed the ring. In Black Yoshi's Mistake!, Mario proposed to Rosalina, and Roslaina accepted, and they are now going to be married some time in the future.
While Mario thought that Mama Luigi was retarded, he was Mario's favorite friend. This is because of all of the wacky and crazy adventures they had in the series of Mario & Luigi's Stupid & Dumb Adventures. Mama Luigi was stupid and nonsensical, and loved Mario, and vice-versa. This is why his death was the saddest death in MLSDA.
Luigi is Mario's brother. While they don't hang out with each other a lot, and he isn't in many videos, they are still really good friends and brothers.
Mario, like everyone else, hates Toad. Toad even got him arrested when was beating up Black Yoshi for killing Peach. Mario once helped Mama Luigi beat Toad up for touching his nickel. However, Toad is seen traveling around with him in a few videos like The Big Thanksgiving.
Mario sorta likes Shrek but gets annoyed at Shrek due to his constant begging for him to buy him cheesecake and walking all over him. But in the early videos, Mario and Shrek got along better. He also dislikes Shrek because he calls him "Donkey" and freeloads off him.
Mario usually hates Bowser. He hates Bowser because he's always kidnapping Peach. Mario also hates bowser because he killed Mama Luigi, Luigi, and Peach in Mario and Luigi's stupid and dumb adventures. In Mario and Bowser's Crazy and Stupid adventures, like the title suggests Mario pairs up with Bowser to find who kidnapped Peach (and Charleyyy that he saw on TV got kidnapped and without Mario knowing, he later finds out that the scene where Charleyyy was being kidnapped was part of the script). They don't like the fact that they're working together, however, the duo works together to come up with great ideas like torturing Sonic to get answers. They have also started to team up in adventures in newer episodes.
Mario was married to Peach for a long time. However, when Peach got pregnant, she started yelling and being rude to Mario. Despite this, Mario still loved her, however. However, when Peach found out that Mario was bald, Peach got a divorce with Mario and he was heartbroken. Mario still liked Peach and wanted to remarry her. When Mario found out that Peach was pregnant with Sonic's baby, Mario hated Peach.
In and Bowser's Crazy and Stupid Adventures, wanted to save Peach and hope that she will love him again. When he saves her, Peach tells that if she saves her baby, she will love him forever. When and Bowser save her baby, finds out that Peach likes as a brother and tells that they can start their relationship over and then get married (which they never did). daydreams of killing Peach after she double crosses him in MABSACA.
In Mario's Valentines Day Problem!, he tried to re-date Peach by pretending Rosalina's gifts were for Peach. Thankfully, he realized that she was being a jerk and permanently dumped Peach to stay with Rosalina.
Mario met Bowser Junior once. But it is known that Mario hates Junior because he kidnapped Peach in the Mario and Bowser's Stupid and Crazy Adventures series.
In Bowser Junior's Game Night 3, it is stated that Mario and Junior have never met, since, according to both Mario and Chef Pee Pee, they have never been in the same video before. This is not true because they actually have been in several videos together and then there's the fact that it's been established many times that they know each other, but it's possible they may have forgotten about each other. Since Logan plays both characters, it makes sense as to why them appearing in the same scene is extremely rare.
Mario hates Sonic. While Sonic has only appeared in a few videos, Mario hates his guts. Mario hates Sonic because he is a rival and that Sonic was dating Peach. In the end of MBCSA, Sonic died so that Mario never has to worry about Sonic ever again.
Mario hates Jeffy because he is annoying and stupid. Although he is protective, such as when he lost Jeffy where he eats, and when Jeffy had a gun, he was looking and telling Jeffy to put the gun down (even though he should've been happy because he wouldn't have to deal with Jeffy anymore). He also shot Jeffy with a Nerf gun in Bowser Junior's Nerf War! In Where's Jeffy? , Mario abandoned Jeffy at the park. However, when Jeffy turned smart, Mario liked him very much and told him that he was proud that he was his son, and was sad when he turned back to normal.
However. in the episode Jeffy's Parents!, it showed Mario's good side on Jeffy. He missed Jeffy when his mother came to take him home. After learning Jeffy's mother was abusive towards him, Mario called the cops on her and had her arrested. Then, instead of sending Jeffy to the orphanage, Mario adopted Jeffy, now officially becoming a legal parent. He even let Jeffy play with his cat piano for one whole day.
Despite their differences, Mario and Jeffy still love each other deep down, and can't live without each other.
Chef Pee Pee
Mario seems to respect and like Chef Pee Pee. Usually interacting with him positively. In The Ring! Chef Pee Pee even helped him try to find his ring,and babysit Jeffy. They do however also compete with eachother on certain occasions, like in The Golden Egg! where they were competing over finding the golden egg first.
Mario has been one of the most well-received characters in the entire SML Universe, and fans claimed in 2016 that Mario was punished for "doing the right thing" in Jeffy's Bad Word!.
However, some fans after Happy Merry Christmas! started to hate Mario because he said inappropriate things to Rosalina and locked Jeffy in a closet, causing a few fans to lose their positive reception for Mario.
In Jeffy's Parents!, Mario did the right thing by adopting Jeffy, making Mario's postive reception come back. To this day, Mario remains a loved character.
Many fans still feel sympathetic for Mario, though, since Rosalina and Jeffy continue to torture Mario, despite Jeffy promising to become a good boy in Jeffy's Parents!, and subsequently breaking his promise in future videos where he goes back to his old ways of torturing Mario, although with some videos showing his improvements.
Mario has lost his status as the main star due to Junior appearing in many more episodes than Mario and his friends. This created the term "SuperBowserJuniorLogan" by a critic, which debuted in Bowser Junior's Macaroni.
In SML canon, all of Mario's adventures in the Mario series happened prior to the beginning of the series, confirmed in Mario's Turtle Problem!.
Logan had Lovell hold Mario in a couple of MLSDA episodes for an unknown reason.
Mario's plush is a Mario Party 5 Plush which is rare nowadays.
Mario is starting to get convicted of doing bad stuff to people or that he shouldn't do because whenever Jeffy does bad things he never gets in trouble and ends up having people blame Mario for what Jeffy did, but he doesn't do anything wrong. They think that he lies all the time.
In The Hitman!, he acts like a deuteragonist as he helps the Loan Dolphin with his evil plan.
In the Super Mario (Nintendo) universe, Mario's birthday was actually on October 11 while in the SML universe, his birthday is in November, the date is currently unknown.
Mario was born on many different years during SML Movies. His Nintendo birthyear was in the 1980s and Logan had stuck with it in early SML Movies, however Bowser Junior's Clown Car! states that he attended his senior year of high school in 1985, meaning he was born in 1967. In Episode 1 of Who Wants To Be A Millionaire? Mario states his first game started in 1942, implying he is in his 70s.
Mario is very durable. He was able to survive hypersonic punches from Sonic.
