Tito Jimenez (adult in "Jeffy's Puberty!")
He is the first and oldest child of Nancy and Jacques Pierre François, and the older brother of Feebee, but since his biological father Jacques faked his death and after he killed Nancy by shooting her in the head in "Jeffy's 18th Birthday!", he is now the adoptive child of Marvin and his wife, Rose.[6][7] Despite this, he still has his clone, Scooter, who is currently wandering around outside of Mario's house somewhere.

The things that he does in his everyday life is annoying and torturing Marvin, hanging out with Junior and his friends, causing trouble, hating school, making messes, throwing plates full of green beans, eating chocolate cake, and much, much more.

Jeffy was born on August 21, 2004, and grew up in the deprived environment of the suburbs with his mom. He never attended school due to his mom's irresponsibility and his father forgetting about him. He also lost his toes through an unknown incident. This was seen in "Jeffy Breaks His Leg!".

He also drives a 2007 Chrysler PT Cruiser convertible aka the PP Cruiser.

He formerly had a 2020 Chevrolet Corvette C8 and a 2001 Buick LeSabre aka Jeffy's spray-painted car.

Born in Paris, Jeffy moved to Florida in 2005 with Feebee, his little sister, who was later killed in a bike accident in 2015 as Nancy took her helmet to use as an ashtray. Her death was the reason why Jeffy always wears his helmet wherever he goes.

After Nancy had enough of his antics, Jeffy was dropped off at Mario and Bowser's apartment lot. Jeffy lived with Mario and his family in the apartment (Causing havoc around the house, especially towards Mario), although the latter hated him before being evicted from the apartment and having to relocate to the new house.

After his wealthy father faked committing suicide and willed his money to Jeffy, Nancy returned to reclaim Jeffy in order to receive Jacques' money when Jeffy turns 18, but was arrested and incarcerated for child abuse, prostitution, and several other crimes. After Nancy's arrest, Mario chose to officially adopt Jeffy as his son and the two now begin to bond every day.

As of today, he is still Mario’s now adopted son and spends his days misbehaving and torturing the latter, playing with Junior and his friends and continuing to cause havoc and destruction.

Ever since during 2020, Jeffy has begun to suddenly become smart and helpful on rare occasions such as the time when he became a detective to help Mario getting out of jail and the time when he watch a scary movie with Mario, and Mario keep lying about the strawman movie while Jeffy proves he is lying. But despite this, Jeffy still loves his family.

He is also shown to be heartless, as shown in "Jeffy the Doughnut King!", where Brooklyn T. Guy told him that his boss was dying because he hadn't eaten a donut, but he didn't care, and he just replied by saying he was bored.

Jeffy has been raised in poverty due to his father abandoning Jeffy alongside his mom and sister.

Jeffy has gone to different places with his mom before abandonment.

Jeffy is somewhat different than the average young adult, with a tall and slim posture. He wears a blue bicycle helmet (with brown messy hair under it), usually has a pencil shoved up his nose, has blue crossed eyes, along with a yellow T-shirt that reads "jeffy" on it which his mother wrote so he would not forget his name. Apparently, when a different word is written on it, he thinks his name is that word as seen in Jeffy’s shirt when Junior wrote “poopy butt” on it. Jeffy thought it was his actual name to the point of losing 100,000,000 dollars because of it.

He wears short dark blue jeans with a Pamper diaper (which, according to Jeffy himself, is on the outside so it doesn't get dirty), which he occasionally spanks. He wears black Adidas sneakers. His biological appearance seems to be mixed between his parents, with his blue eyes inherited from his mother and his dark brown hair inherited from his father. His face is oval shaped with two teeth and around the nose, along with two eyelashes and a uni

History
BabyJeffy
Jeffy as a baby
Jeffy was born on August 21, 2004, and grew up in the deprived environment of the suburbs with his mom. He never attended school due to his mom's irresponsibility and his father forgetting about him. He also lost his toes through an unknown incident. This was seen in "Jeffy Breaks His Leg!".

Jeffy has been raised in poverty due to his father abandoning Jeffy alongside his mom and sister.

Jeffy has gone to different places with his mom before abandonment.

He is also shown to be heartless, as shown in "Jeffy the Doughnut King!", where Brooklyn T. Guy told him that his boss was dying because he hadn't eaten a donut, but he didn't care, and he just replied by saying he was bored.

Appearance
Jeffy is somewhat different than the average young adult, with a tall and slim posture. He wears a blue bicycle helmet (with brown messy hair under it), usually has a pencil shoved up his nose, has blue crossed eyes, along with a yellow T-shirt that reads "jeffy" on it which his mother wrote so he would not forget his name. Apparently, when a different word is written on it, he thinks his name is that word as seen in Jeffy’s shirt when Junior wrote “poopy butt” on it. Jeffy thought it was his actual name to the point of losing 100,000,000 dollars because of it.

He wears short dark blue jeans with a Pamper diaper (which, according to Jeffy himself, is on the outside so it doesn't get dirty), which he occasionally spanks. He wears black Adidas sneakers. His biological appearance seems to be mixed between his parents, with his blue eyes inherited from his mother and his dark brown hair inherited from his father. His face is oval shaped with two teeth and around the nose, along with two eyelashes and a unibrow.

Personality
"Jeffy, you know what? You're so hard to raise! You don't listen, you argue and you break stuff!"
— Mario confronting Jeffy for his lack of niceness in Jeffy's Switcheroo!.
Jeffy started off as a mentally disabled stereotype, before changing into a stupid and misbehaved person who swears like a sailor, explodes in anger at any slight against him, and knows a lot about perverted acts for someone his age. Over time, he has matured and does not annoy Mario and Rosalina as much as he used to. He barely swears anymore and only acts more like a troublesome child. He is also known to be very strong, possibly one of the strongest characters in SML, as he tends to beat up bullies, hit balls really hard, and has a high pain tolerance. Overall, Jeffy's personality has gone through more changes than any other character in SML.

He has a habit of spanking his diaper placed outside of his pants as well as soiling his pants often. When he is called a "bad boy" or in some cases a "r\*\*\*\*d", he tends to have a breakdown by throwing his head and hitting it onto any surface but calms down when he is called a "good boy" (this is no longer the case after the events of Jeffy Loses His Pencil!). However, his breakdowns can become extreme and violent, which involves curse words and being rude towards Mario and Rosalina. He also flips his desk in "First Day Of School!" because the teacher (Who is Jackie Chu) assigned a 10-page essay that was due the next day and cusses (mostly the F-word) at Jackie Chu, saying "ARE YOU FUCKING HIGH?!" He often says "Why?" whenever someone tells him what to do or what not to do. He even keeps saying it whenever someone answers him. He also has a habit of calling things he likes "pee-pee." He also often says "I don't even know" when asked questions.

He likes to put his "pee-pee" in various objects, especially Cheerios boxes, to the point where he somehow even impregnates one and develops romantic feelings for it.

He deeply resents Bully Bill, who picks on him and subsequently beats up all the time, but the person he hates even more is his teacher, Jackie Chu.

He is also afraid of trivial and ridiculous things, such as animals, toilets, snow, ostriches, a flu shot, and the number 7. Based on characteristics, it is suggested that he has mental disability. His mother delivered him to Mario because she did not love him for unknown reasons (according to Jeffy). He also has a fear of water. This is shown in Jeffy's Bathtime!, when he refused to take a bath. It is also shown in Jeffy's Swimming Lessons!, when he refused to take the swimming lessons and would scream when in water. Because he has a huge fear of water he would drown almost immediately. This is shown in Jeffy's Swimming Pool!, when he drowned in the pool due to his difficulties of swimming.

Despite not being that intelligent, Jeffy has shown traits of intelligence, but in a stupid way at times, such as in Jeffy's Homework! when he reasoned that the equation 8-4=8, since they are taking 4 out of the equation, even going on a profanity-laced rant as well as getting very smart over the years as Mario thinks he will not notice anything or remember anything but he does so he is not very dumb anymore. He is also an extremely skilled painter, a trait passed down from his father. He has also shown signs of intelligence as in Jeffy Gets Ran Over, where he remembers everything that happened to him after getting knocked out by Mario's car, as well as knowing that Mario is the one that hit him.

Jeffy has shown to be demanding, even more than the level Junior displays, as seen in Jeffy's Bedtime!, where he demands that Mario and Rosalina make his green eggs and ham, "Jeffy Gets Potty Trained!" when he demands that Rosalina give him marshmallows instead of peas, "The Hitman!", where he wanted Jello after Mario gave him green beans, he refused to eat his McDonald's Chicken Nuggets because he wasn't given 20 toys and threw them away, in "Locked Out", where he demanded chocolate cake, cried when Mario didn't give him it and locked Mario out to enjoy the cake, especially in front of Mario, and in "Jeffy Gets Help", when Jeffy yells, screams, and throws a temper tantrum because Mario said that he would not watch SpongeBob SquarePants.

Jeffy is shown to enjoy playing pranks, as seen in "Jeffy's Cellphone!", where he prank calls several places, including an employee named Josh and a prostitute, resulting Rosalina thinking Mario is cheating and beating on Mario, and in "Shrek The Babysitter!", where he locks Shrek in the bathroom with the help of Bowser Junior. Both of these videos shows that he seems to be less unintelligent, causing many fans to think that this could be a normal version of Jeffy, despite all of his intelligent moments in the series. Some people [who?] think Jeffy pretends to be mentally disabled. When his real mother Nancy tried to claim him back, Jeffy begged Mario to let him stay and promised to be a good boy (and kept his promise by not playing the cat piano when he went back inside), indicating that he loves Mario very much. Jeffy's obsession with swearing may be from his mother and the way she acted in front of him and treated him.

Despite of all this, he is generally more on the friendly side and the bad things he does is mostly due to his unintelligence. He has his fair share of good deeds that battle the evil ones, such as being considerate to Hansel in three episodes. He is most likely misunderstood after suffering pain from his biological mother and witnessing his twin sister's death, which might explain his outburst problems.

Although he is unintelligent, he was shown to be an adult to Mario in some episodes such as the time when he caught Mario spilling water all over his bed and Mario wanting to play with his Lego rather than eating his food. And sometimes he does not like to believe people like in The Halloween Heist.

Throughout his time in the series, his intelligence has steadily increased; as of 2022, he is of average intellect, able to come up with clever plans (such as in Jeffy and Junior's Big Heist!) and successfully escaping from his mother in Jeffy's 18th Birthday!.

Controversy
Jeffy has proven numerous times to be one of, if not SML's most controversial character. Many fans have criticized him, ever since his debut, saying that he's an offensive stereotype of the mentally disabled. Logan responded to these claims by saying that Jeffy was meant to be similar in-vain to Chef Poo Poo, not mentally disabled.

After "Jeffy's Bad Word!" and "Locked Out" were released, Jeffy received an immense amount of hate from older fans, due to his downright, horrible behaviour towards Mario that would usually land him in trouble, due to Jeffy lying. Worse, Jeffy had now begun to grow a fanbase, of mostly children and young teenagers, adding even more controversy. After "Jeffy's Parents!", despite some still hating him, most started to feel sympathy towards him, due to the reveal of his backstory, with his mother, Nancy.

Jeffy's fanbase, only grew more when "Jeffy The Rapper!" and "Jeffy's Fidget Spinner!" were released. These videos exploded in popularity, and caused children to fall in love with Jeffy. Getting to a point, that some even began treating him like a god. Older fans immediately took immense hatred towards Jeffy's newfound fanbase, due to their constant demand for more Jeffy videos, disliking ANY that didn't feature him. In "Jeffy's Fun Day!", he received a poor reception. Whilst never confirmed on whether or not some had begun treating Jeffy like a god, an example of what they could be like, can be seen in the SML Creepypasta, Not As They Seem, in which they served as the main antagonists. They're portrayed, as a group of six completely insane individuals, who's devotion to Jeffy had reached reached a point, that they had created an entire religion around him. Worse, Jeffy was now starting to be imitated by his young viewers.

On December 12th 2017, UK tabloid company The Sun, reported that a seven-year-old boy had attempted to hang himself with a noose, in a similar way to how Jeffy almost did in the now-deleted, and infamous, "Jeffy's Tantrum!". The mother of the child discovered this and reported the news to The Sun. Rather than blaming herself, however, she chose to blame Logan. The article can be viewed here. Logan then apologized and assured that his videos are not to be imitated; despite this, YouTube started demonetizing and age-restricting all of his videos. A few months later, "Jeffy The Rapper!" was reported on by the news, as second to third-grade-children were now being disciplined after mimicking Jeffy's behaviour (mostly boys). A now privated YouTube video showed an entire school bus of children singing Jeffy's song in the video, "Why?".

In late 2018 and early 2019, Jeffy had now become universally despised, as his actions and use of words were deemed inappropriate by many. The younger fans began outnumbering the older fans, by pressuring Logan to make more Jeffy videos, to the point that every video, where Jeffy was absent, such as "Toad's Mistake!" (2017) and "Attack of the Killer Shrimp!" were panned by younger viewers simply because he wasn't there. Worse, classic characters like Woody, Shrek, and Mr. Pig, were heavily affected by Jeffy's takeover, as his increase in popularity, caused them to rarely, or in the case of some, never appear again. During the break-up drama in 2020, it was revealed that Chilly had pressured Logan to push Jeffy as SML's main star.

Jeffy's popularity has now reached a point that Logan is incapable of writing, or killing him off, without losing most of his subscribers, resulting in him instead coming back in some way, even after he appears to have actually been killed; worse Logan's address is publicly known, meaning if Jeffy were to be removed from the series, he would put his house, and friends, at risk, of being attacked, by hundreds, if not, thousands of angry Jeffy fans. Not as They Seem, also points this out, as the creepypasta's main protagonist, Cassey Green, stated that Logan would lose the same amount of, if not, more subscribers, than he did when Mama Luigi was killed off, if he were to do the same to Jeffy.

In modern day, the SML fanbase has accepted that Jeffy's stay is permanent, and has gotten used to the fact that he's SML's breakout star, and the mascot of the channel. It's not to say that not everyone has accepted this, however, as to this day, Jeffy remains heavily disliked by a big portion of the internet.

Pets
Pee Pee Suck (fish)

Pee Pee Suck was Jeffy’s pet fish that made an appearance in “Jeffy's Pet!.” However, Jeffy later ate him whole. His skeleton was seen in Jeffy Gets Stung by a Bee!.

Pee Pee Suck 2 (hamster)

Pee Pee Suck 2 was Jeffy’s hamster from "Jeffy's Pet!". She is also known as Melvin. However, in "Jeffy's Dog!", she went missing, and Brooklyn Guy was her new owner. She was mentioned to be dead in "Bowser Junior the Faker!".

Poopy Butt

Poopy Butt, formerly called Shitass was Jeffy’s dog from "Jeffy's Dog!". He was paralyzed from the neck down, because Rosalina got him from the animal shelter. His first death was in "Jeffy Gets Glasses!", where he was euthanized. In "Jeffy's Bad Dog!", he died from chocolate poisoning, but was later revived. In "Jeffy's Swimming Lessons!", he drowned. He was seemingly gone for good, as he didn’t appear again after that, however, he returned in "Mr. Goodman's Dog!".

Booger

Booger was a more exotic pet that Jeffy had. In "Jeffy's Pet Dinosaur!", he hatched Booger from an egg. However, it was a bad idea to keep Booger, because he isn’t house-trained. Mario once sold him to the Loan Dolphin in "Brooklyn Guy Pet Detective!". Also, Booger stopped appearing after "Jeffy Plays Baseball!", so it’s unknown if Jeffy still has Booger. However, this changed in "It's Ya Boy Duggie!", where it's shown that Jeffy has kept Booger as a pet. Booger was also revealed to be female in "Jeffy's Eggs!".

Orange Zebra

Orange Zebra was another exotic pet. He made his first appearance in "Jeffy's Pet Tiger!". However, he was way too dangerous to keep.

Loan Dolphin

Loan Dolphin was Jeffy’s temporary pet in "Jeffy's Pet Dolphin!".

Inventions
So far Jeffy has only created one invention, and that is the Piss Pal.

Piss Pal ("Jeffy's Invention!"): A smiley-faced sponge that is used for preventing peeing in someone's pants and reusing them every time someone uses one. On Shark Tank, Jeffy receives one million dollars after Pooby makes a deal with him. This then leads to him getting a cease-and-desist letter from the original company. The Piss Pal is actually a Scrub Daddy, the original invention that Jeffy stole from.
Children
Please note that most of them have died.

Puss Hole

Puss Hole is a baby boy, one of Jeffy’s children from "Jeffy's Kids!". He was later "murdered" by Bowser Junior.

Puss Hole 2

Puss Hole 2 is a baby girl, one of Jeffy’s children from "Jeffy's Kids!". She was later "murdered" by Bowser Junior.

Jeffy Junior I

Jeffy Junior I was Jeffy’s other kid from "Jeffy's Kids!". He looked a lot like Jeffy, except he was covered with Cheerios and had darker skin than Jeffy. And he always shit his pants. When Jeffy tries to potty train him, he flushes himself down the toilet, presumably drowning him.

Jeffy Junior II

Jeffy Junior II is a hybrid of Jeffy and Junior from "Pregnant Jeffy!". He was made thanks to Harry's impregnator. Jeffy Junior II was proven to be super annoying, but he also likes Mac and cheese like Junior and cat piano like Jeffy. Later, he destroys Junior’s Golden Thomas, and Jeffy’s cat piano. Jeffy Junior II was later sold to Jackie Chu.

No bun or anything because I like to watch them roll around.

Because if they do, then you're gonna have to start all over again. And then to drink, I want some of the water that the hotdogs were cooked in with milk.
