For information about the Super Mario version of this character, go here.
|Please note the following:
Robert "Bowser" Bernard Koopa Junior.  usually referred to as Bowser Junior, or simply Junior is one of the main characters in the SuperMarioLogan series. His and Bowser's real names were revealed to be Robert in "The Koopa Kids!", however, that video was non-canon as the Koopalings miniseries was a remake. However, their name of Robert might be revealed as canon sometime in the future to help comply with the cease and desist order when Bowser is to be called by his biological name.
From 2013 to mid 2016, he was the spoiled son of Bowser, and was usually parented by Chef Pee Pee, who was constantly annoyed by him. However, as of late 2016 to onwards, he became somewhat more mature. His relationship with Bowser improved to the point where they both love each other and started to bond everyday. Currently Junior rarely bothers Chef Pee Pee, however, Chef Pee Pee still hates him.
In his early years, he was the arch-enemy of Brooklyn T. Guy and Principal Steinbeck. However in later years, he is sometimes the arch-rival of Chef Pee Pee.

Bowser Junior's personality was extremely variant in earlier videos and over time has had numerous different sides to him.
From 2013 to early 2016, he is shown to be bratty, annoying, racist, dimwitted, whiny, demanding, and mindless and most fans hated him.
Junior is known for being an annoyance to everyone around the house, especially towards Chef Pee Pee, and always caused a disruption that usually leads to Bowser yelling at Chef Pee Pee for it or sometimes vice/versa.
Whenever he asks for something, he usually pesters Chef Pee Pee asking for what he wants. On many occasions, he asks for something very stupid such as in "Bowser Junior's Midnight Snack!" when he asks Chef Pee Pee to buy him a snack at the gas station even though Chef Pee Pee told Junior that there is a mountain of snacks to eat at the house.
He is also a somewhat picky eater especially in later videos and was also a spoiled brat because in "Bowser Junior's Summer Vacation", he demanded Chef Pee Pee to buy him all the trains but he only got two from the store. Junior loves his train toy Thomas a lot, so he gets depressed if he loses it as shown in "Bowser Junior Loses Thomas!"
He also got rabies and started acting weird in "Bowser Junior Gets Rabies!". When the rabid squirrel bit him, he turned into a wild animal and was foaming at the mouth. Chef Pee Pee gave him a pill and that made Junior feel better and then he bit him. At the end of the video, Bowser Junior said that "Chef Pee Pee was having "babies" himself.
One of the most notable things about Junior is how he has changed over time. In his first appearances in 2013-14, Junior was portrayed as a spoiled brat who portrayed a general child that age.
As of 2015, Junior started to become smarter and more intelligent, but still was stupid sometimes when he was with Joseph and Cody. Since Bowser Junior has turned 8, he has gotten a bit more mature.
One notable video with this was "The Baby Project!" where Junior was strongly encouraged to do as good as possible and fighting the retardedness of Jeffy. It is a very unique aspect of how Junior is growing over time since he stopped acting bratty over his early years.
It's pretty apparent that Junior has some serious mental instability, if anything happens that may affect him badly, or something doesn't go his way, he will react in very unhinged and insane episodes.
In "Bowser Junior Needs Glasses!" Junior wore glasses and his friends made fun of him so he read a medical book and got smarter and thinks he's smarter than everyone.
In "Bowser Junior's Flu Shot!" Junior was scarred after he got his flu shot and was on a wheelchair and wore a cast on his leg where he got his flu shot and claims to have been "shot" by the Brooklyn guy.
And in "Bowser Junior's Cookies!" He left a sticky note which had cookies written on the fridge and was hoping for Chef Pee Pee to get him cookies but Chef Pee Pee said that he didn't see it and Junior kept repeating he didn't see it and placed sticky notes all over the house and the car. It's also noted that Junior doesn't have a sense of empathy because he told Joseph to stop crying over his “dead” mom in "Bowser Junior Sneaks Into A Movie!".
On several occasions, he is found to racially prejudice black people. This is evident in "Black Yoshi's Job" (Black Yoshi is asked to babysit Junior while Bowser and Chef Pee Pee go to the hospital) when Junior is surprised to see Black Yoshi walk up to him while he is playing with his dinosaurs. Junior cries, "Oh my god! Black Guy! Don't take my money! Protect me, dinosaurs!" Black Yoshi then asks, "Why is everyone in this house so racist?"
Junior is also known for sharing fake stories. For example, in "Bowser Junior's Flu Shot!", He explains to Joseph and Cody that a guy came in with a gun, shot Bowser and Chef Pee Pee, and getting shot in the knee.
Also, in "No Crust!", he explains to the Brooklyn Guy that Chef Pee Pee used a chainsaw to "kill" his sandwich, in reality, all he did was cut the crust. In "Chef Pee Pee The Octopus!", he falsely said Chef Pee Pee wants to be an octopus. In the video "Loch Ness Monster!" Junior showed a fake video and lied about it for a while. Though he did owe up to it in the end.
He has made extremely poor choices on more than one occasion such as in Bowser Junior gets Rabies and Bowser Junior's Doll like trying to pet a rabid squirrel and trying to throw water bombs in the house respectively and lacks common sense which leads to him being half dumb.
However, despite all of this, even Junior is capable of genuine kindness, the shining example of this is when he felt bad for Chef Pee Pee's suffering on his birthday, and as an apology, threw a surprise birthday party for him, with Joseph and Cody's help! He even apologizes for treating Chef Pee pee badly for the entire time they've known each other (although, thanks to the new status quo, this is rendered redundant via negative continuity).
Despite being a generally dumb character, he has shown to act smart on some occasions such as "Bowser Junior's 1st Grade! Part 5" where he states that blue stars are hotter than red stars, in "Cool Cody!" where Bowser Junior figures out how to change Cody back to normal, in "Bowser Junior's Bad Luck!" he states that superstitions are not real and that all the bad luck he was getting were coincidences.
In "Bowser Junior's Piggy Bank!" he knows how to stop his dad from getting arrested without getting himself in trouble and in "BroKEN" where he has the idea to put the one-piece tuxedo on Ken and give it to Cody so he stops crying. Along with Joseph, Bowser Junior keeps trying to prove to Cody that Ken is a doll and that the Sun is a planet (although he no longer seems to argue this after "Bowser Junior Goes To The Sun!"). He also uses a bowling ball, a trail of Cheez-It, an oven, a golden watch, and an electrified doorknob as a trap to kill 3 robbers (1 survived but was imprisoned).
As of late 2016 or early 2017, He doesn't act very bratty anymore, as he improved from military school. He's also simply grown up over the past few years, as he was just 4 in his first modern appearance. Despite this, however, Bowser Junior’s brattiness returns at the beginning of "Bowser Junior's 9th Birthday!" where his father punished him for destroying his flat-screen TV but the best example of this is in "Bowser's Christmas Problem" where Bowser explained to him that Santa Claus isn't real though this was never spoken of him again. Starting from Season 9 and Onwards, He has retired from being a brat, he became more mature, more good Koopa-being and fans started to love him as a mature, and a good person. He and Joseph both think the sun is a planet because of its spherical shape.
As of late 2019, Junior has reverted back to his bratty and stupid nature. This is evident in The School Project when he makes up excuses to make Cody seem more guilty when he accidentally destroyed his helicopter and takes revenge by destroying his project. He also likes to accuse Cody for poor reasons such as assuming he forgot about his birthday in Bowser Junior's 21st Birthday and decides to threaten Cody in Bowser Junior's Revenge. He also has a habit of confusing simple English such as thinking the word "Birthday" is actually 2 words.
As of 2021, Junior has become far more ignorant, mean and malicious as of recent videos. In Cody's New Friend!, Junior decided to get Cody's terminally sick friend Luke Emia arrested just to get Cody to hang out with him again. On top of that, Junior has completely forgotten the concept of cancer and death and thinks dying means going to space. In Juniors IPad!, Junior has also shown heartless behaviour as when Brooklyn T Guy made up a story about a dying kid Junior simply responded with "sucks to suck." Even though the story was made up, this heavily implies that Junior no longer cares about other people and only cares about himself which is a major downgrade from his 2016-2019 self.
- Caring (Sometimes)
When Bowser Junior was born, he started as an evil baby who burnt Mario and kidnapped Peach until Black Yoshi wounded him. Following the end of MLSDA, Bowser started dating Shelby, but she would later leave him, leaving Bowser Junior with no mother. Bowser would always choke his son with cotton balls, causing his fears of it.
Now Junior spends his days hanging out with Cody, Joseph and Jeffy, as well as Toad (off-screen nowadays).
Chef Pee Pee
In earlier videos, Bowser Junior always annoyed Chef Pee Pee with his stupid requests, making Chef Pee Pee hate him. Because of this, every time when Junior is about to do something that could be dangerous in some way. In later videos, He would stop bothering Chef Pee Pee and ask him for something, even though Chef Pee Pee still hates him.
Chef Pee Pee, similar to his hopes and dreams of killing Bowser, sometimes hopes he kills Junior in the process, but sadly for Chef Pee Pee, this never happens. He also annoys him by asking to play toys with him. Junior loves spending time with Chef Pee Pee but he never showed love back to Junior, There are rare occasions where Chef Pee Pee is nice to Junior, such as at the end of Bowser Junior's Big Vacation!, taking him to Disney World without so much as a complaint. For some reason, he is not angry or insulted from Chef Pee Pee calling him a Brat/Idiot/Slut.
In the SML Movie “Bowser Junior’s Doll!”, Junior has made a better hatred for Chef Pee because he thinks that he is a snitch. When Chef Pee Pee goes to Junior's room while wearing disguises, He said “Nah, it’s just me n**ga!” and leaves his room in laughter much to Junior's Fury. As Chef Pee Pee gives Junior a bowl of macaroni and cheese, he was tricking him to give him macaroni and cheese much to Junior's Fury. As Junior has had enough with Chef Pee Pee for pranking him, He gets the voodoo doll and thinks that the voodoo doll is Chef Pee Pee and begins to hit it and send it off to space along with Chef Pee Pee being send off to Space. As Junior tries to apologize to Chef Pee Pee for his selfish behavior, he was wondering where he is. As Chef Pee Pee was suffocating to death in space, He yells to Junior's name.
In "Bowser Junior's New Room!", Junior is now Chef Pee Pee's roommate, much to the despair and annoyance of the latter, yet to the pleasure do the former because Junior's old room was taken over by his father as punishment for eating his strawberry donut and sneaking out of his room. After Junior says he loves him, Chef Pee Pee mutters the same, yet does not say it directly to Junior.
As of Bowser Junior's Prank Gone Wrong!, it's safe to say that Junior has lost every form of respect toward Chef Pee Pee, making him deaf and wishing he never existed. It's also clear that Junior is very hypocritical towards Chef Pee Pee as when the latter has shown to care for him such as in Bowser Junior's Rat Problem, Junior never seems to return the favor.
Status: Neutral (Enemies on Chef Pee Pee’s side)
Bowser Junior frequently interrupts his dad while he watches Charleyyy and Friends. Bowser occasionally likes his son, but he hates when he annoys him. He basically annoys him a lot and sometimes it leads to Bowser getting on him and on more than one occasion abuse him. However, this was in older episodes. In later episodes, Bowser showed his good side to Junior, saying that he loves his son even though he still hates when he annoys him. But despite this, Bowser would always protect his son no matter what.
Status: Neutral (Friends on Junior’s side)
Bowser Junior and Joseph (whose last name being "His Friend From School") are friends that mostly meet at school or at Junior's home to play toys. What often happens is, if somebody is cooler than Junior, Joseph is on their side rather than on Junior's side. They have surprisingly made out a lot, especially in the Playtime Series.
In certain episodes, Joseph and Junior do not get along. For example, when Joseph got a new shell in Joseph's New Shell!, Joseph started bullying him and even beat him up with his new friends. Junior also invited Joseph over for a sleepover in Bowser Junior's Wings!, when he attempted to break Joseph's wings with a hammer because he was jealous of his new shell as it meant stealing the girl he had a crush on.
On some occasions, Junior can be very harsh to Joseph. For example, in "The South Pole Santa!", when Joseph suggested adding milk to the hot chocolate, Junior had a fit and poured the hot water on Joseph giving him third degree burns and in "Joseph's New Shell!", he ignored Joseph's injury by eating Cheeto's instead.
Bowser Junior and Cody get along pretty well with each other. Like Joseph, he invites Cody to his house regularly. There are many times when Bowser Junior is really mean and harsh to Cody. Cody keeps trying to tell him the truth about things (like the Sun being a star, Pluto no longer being a planet or the Earth being round), but Junior never listens and his nonsensical logic and denial make it unfairly hard and stressful for Cody to reason with him. In The School Project!, Cody and Junior got into an argument because he broke Junior's toy. Joseph also took Cody's side as they both told Junior it was an accident.
Cody sometimes even acts very harsh towards Junior like in Cody's Revenge where Cody had enough of Junior bullying him and decides to blackmail him and if Junior doesn't do whatever Cody says he will tell his dad that he broke a bowl. Throughout Cody's Revenge, Cody has cruel towards Junior by making him do stuff that he defiantly will regret. Cody even ruins Bowser Junior's Golden Thomas.
Cody is shown to be very bisexual towards Bowser Junior as every chance he gets, he will try to moleste and/or spank him. While Junior is very well aware of this. He will always be Cody's best friend but Cody fails to see this. In The Remote! Cody uses the remote to rape Junior along with everyone else in the world for 5 years. Cody also likes to take advantage of Junior's loyalty.
Most of the time, Junior likes to make fun of Cody's mom because of how fat she is by calling her animal names and how she should be in the ocean or a Zoo. While Cody sometimes ignores this, Junior's jokes can go way too far which makes Cody want to beat him down or even joke about how Bowser Junior doesn't know his real mom. In the present, Cody is now used to Junior making fun of his mom.
Status: Friends (enemies on some occasions)
Before late 2016 Bowser Junior usually hung out with Toad. They were very good friends, although Toad usually got Junior in trouble, such as in April Fools!. This was in the older episodes. Later on, their friendship came to an end when Bowser Junior matured more. Junior later moved on to hang out with Cody, Joseph, Jeffy, and Richard Goodman. Toad would later lose his status as the main character as of mid-late 2017, and Bowser Junior hung out with him less frequently.
Status: Friends (formerly best friends)
Even though they rarely interact with each other, they seem to get along quite well in the recent episodes. In Bowser Junior's Game Night 3, They can get along well when yelling at Jeffy. They often get along well too in Jeffy's Birthday! and Smart Jeffy and says that whenever Junior is around, Jeffy gets less involved with him. However, in Mario and Bowser's Stupid and Crazy Adventure, Mario implied that he hated Junior. Despite that, in the recent videos, they often get along well.
Status: Friends (enemies originally)
Bowser Junior met Jeffy for the first time in Bowser Junior's Game Night 3. At first, Junior thought Jeffy was weird but overtime, the two bond and start a strong relationship. In recent videos, Junior and Jeffy go on adventures, play together more frequently and even do criminal activity together.
However, there are some rare occasions where Jeffy and Junior betray each other in certain situations. For example in Jeffy's Punishment!. Junior gets mad at Jeffy to reacting to being shocked and even wants him to leave the school.
In Jeffy's Kids!. Junior sees Jeffy's kids and starts eating them. Jeffy sees Junior for eating P*ss hole 1 and 2 and even calls the police to have him arrested leaving Junior confused and upset because he never knew P*ss hole 1 and 2 were Jeffy's actual kids.
In Jeffy's Pokemon Card!. Jeffy betrays Junior once again by being selfish about a Pollytoad-EX which was the only Polly Junior was missing in his collection. Junior then began to develop a hatred for Jeffy throughout the episode. At the end, all was lost when Jeffy burns the Pollytoad-EX in front of Junior leaving him upset.
But currently. The duo seems to get along just fine, while Junior deals with Jeffy's lack of intelligence and Jeffy deals with Junior's problems with life. The two share a strong relationship and together. They do all sorts of misadventures. Like when they skipped school in Jeffy and Junior Skip School!, they sneaked out of the house without permission in Jeffy and Junior Sneak Out!, they sneaked away to Disney World during a pandemic in Jeffy and Junior Sneak to Disney World!, they even went to prison together in Jeffy and Junior Go To Prison!.
In Smart Jeffy, Junior caught Rosalina's attention by calling her "Busty Tits" and told her that Jeffy had an accident on the trampoline that was in his playroom. In Jeffy and Junior Sneak To Disney World!, he, along with Jeffy and Joseph were caught by Rosalina. Bowser Junior calls her an old lady.
But it's unknown if these two characters share a good relationship or not.
Brooklyn T. Guy
Before Season 9, Junior and The Brooklyn Guy formerly had bad blood against each other. They usually get into big fights in the Home Alone series and they didn’t like each other in the past years.
In Bowser Junior Goes To Military School!, Brooklyn T. Guy, as his full name was revealed, treated Junior and the other students badly, as they went through a dangerous course, as the other students were killed by an explosion, but Junior made it. Brooklyn Gu T.y was impressed. Later, Junior was trapped and ate disgusting things, including nails, and was even forced to watch Big Hero 6, as Brooklyn Guy even burned Thomas. After military school, Junior was not the same.
In Bowser Junior's Package!, he jacked his Gak which caused him to get revenge on him for backstabbing him.
However, this was in the older episodes. Later on, they seemed to get along, but in Jeffy's Kids!, Junior ate Puss Hole 1 and 2, so Jeffy called the cops. Brooklyn T. Guy then arrested him, calling him a “cereal killer”, and he was taken off to jail. But after the release of 2 Tickets, they are now currently friends as their past as enemies are over.
Status: Friends (formerly enemies)
In Bowser Junior's Stinky Friend, Junior was shown to be very sympathetic for Hansel (or "Stinky" as he calls him.) He snuck Hansel into his home and provided him with Chef Pee Pee's bed, as well as cheese balls, earning him the nickname "Cheeseball Man." Later on in the video, he'd try to get Hansel a job as an anesthesiologist, which didn't last very long. Eventually, Junior reluctantly had to kick Hansel out. Hansel stated that he loved Junior and that he'd never forget him before disappearing.
Along with Jeffy, Junior and Bully are secondary archenemies. Junior hates Bully because he took his 'Golden Thomas Train' from him and beats him up, but Junior retaliates by putting 'chopsticks' in his eyes, which causes him to give him back his 'Golden Thomas Train' toy and ran off screaming in pain. He also hates Bully because he always bullies Jeffy and never learns his lessons.
Junior has dark black eyes with white pupils on the underside. He wears a large bib and four small bracelets with two on each arm. He has skinny arms and legs and slightly long fingernails. He also inherits his father's red hair and pale yellow skin.
In his human form, Junior has fair skin, black eyes, short red hair, and horns. He wears a white bib that reads "JR" in black, an orange t-shirt, his black wristbands, green shorts, and orange shoes [his turtle form doesn't have shoes].

- Flight: In Joseph's New Shell! Joseph states that he can fly and junior can’t the hand holding junior fly's him, showing he can fly as well.
- Electrokinesis: In the episode SuperPowers, Junior and his friends get struck by lightning which gives them superpowers. Joseph and Cody get cool superpowers and Junior gets a lame one: Superhuman Flatulence, But, Junior touches them and he shocks them making them realize that he can zap people by touching them. Cody and Joseph and still make fun of him because his power was still lame, So then Junior cries loud and he then zaps a giant wave of electricity which makes them all lose their powers thus ending the episode.
- Super Flatulence: In the same episode, Junior gets super farts which is lame at first but it helped Chef Pee Pee when he needed to throw up.
- Legilimency: In the episode SuperPowers 2, he and his friends went in the microwave to prank Chef Pee Pee. They end up failing and Junior could read people's minds in an instant.

Despite being young, he has a criminal record. Most crimes are due to a lack of common sense and sometimes he did these crimes as revenge. (But he can't be convicted of the crimes due to his age.)

He also murders some other characters like Drawing Jeffy in Drawing Jeffy! and Scooter in Jeffy's Clone!
- Attempted Murder - In Home Alone! he tries to drive Thomas down a train track to kill Brooklyn T. Guy.

- Arson - He starts a bushfire on the 4th of July with illegal fireworks.

- Attempted Arson: In Bowser Junior's Revenge!, he and Joseph attempt to burn Cody's house down using a lighter but Cody's house was made of bricks.
- Kidnapping - He kidnaps Peach in Mario and Bowser's Stupid and Crazy Adventures. In Jeffy's Bad Christmas!, he along with Jeffy and Cody kidnap Santa Claus and hold him hostage.
