Villain Overview

You guys are SO immature!
~ Melvin's catchphrase in the book series.
I don't get it. What's so funny?
~ Melvin's catchphrase in the film.
That rashy goon Diaperado was right. A team is the key to defeating Captain Underpants and achieving Melvindication.
~ Melvin taking about his plans to take over the world.

Melvin Richard Sneedly, also temporarily known as the Bionic Booger Boy, is the secondary antagonist of the Captain Underpants franchise.

He is a child prodigy and perhaps the smartest student currently attending Jerome Horwitz Elementary School, but is also the school's biggest tattletale/sellout when he assists mean teachers for extra credits and is greatly disliked by lots of the students for this reason. He is also George and Harold's rival and "nerdy nemesis".

In the feature film, he was voiced by Jordan Peele of MAD TV fame, who also voiced Beta Wolf in the 2016 Warner Bros. animated film Storks. In The Epic Tales of Captain Underpants, he is voiced by Jorge Diaz. In the scholastic audiobook series, he is voice by Len Forgione.

Personality[]

Melvin is known to be a tattletale and he is arrogant. He is sometimes selfish such as when he refused to save people unless George and Harold changed their comic about him in book 7. However, he was more than willing to save people for a full year as a superhero in book 11, being perfectly willing to help people even if the emergencies were minor and not even caring when he room was severely damaged because a lady needed help.

Unlike most students, Melvin does not have a sense of humor which is the reason why he is Professor Poopypants' henchman in the film.

Just like Mr. Krupp, Melvin hates George and Harold because they are mischievous. However, his anger towards them is justified on a few occasions, like in book 2 where he understandably broke his promise and snitched on them for ruining the science fair for the second year in a row.

However, he was more than willing to rescue George, Harold and Captain Underpants in book 10. In the TV Series’s he frequently team shows up with the heroes and helps them against bigger threats, even if for usually self-serving reasons.

In the Hack-a-ween movie special Melvin reforms and joins George and Harold. It's revealed he only hated Halloween due to being alone and is happy when George and Harold invite him to go with them on Hack-a-ween.

Appearance[]

Melvin has pale tan skin, freckles, and light orange-brown flat hair with some of it swept upward. Melvin wears glasses, a white collared shirt, a red bow tie, a yellow vest, shorts, and brown shoes. In the movie, the frame of Melvin's glasses are green, his bowtie is a golden yellow color, and he sports a watch.

As the Bionic Booger Boy, Melvin retains his spectacles, facial features, and bow tie. However, he is covered in mucus, sports robotic limbs, and is notably taller, a result of him being fused by his Combine-O-Tron 2000 with a robot and his own mucus.

History[]

In the books[]

Melvin debuts in the second book as the local nerd and snitch, who created the PATSY 2000 (a device similar to a 3D printer) as part of a science convention. He tells George and Harold it can bring images to life. They aren't impressed, however. Melvin reluctantly agrees not to mention that he saw the two ruining the science fair in exchange for them not tampering with his PATSY 2000. However, he (rather understandably) changes his mind later when he decides to tattle on George and Harold after the science convention is cancelled because of George and Harold's pranks, which he got caught up in.

When George and Harold use the PATSY 2000 to create copies of their comic book, it spawns the Talking Toilets and the Turbo Toilet 2000, who terrorize the school. Later, Melvin is placed in detention (since he tattled) along with the other teachers when George and Harold become Principals of the Day as they throw an all-day carnival for all of the other students and is forced to write "I will not be a tattletale" multiple times.

Melvin is one of the students who get turned into a zombie nerd by Zorx, Klax & Jennifer in the third book. In the fifth book, he bears witness to the attack of Wedgie Woman's robotic George and Harold.

Melvin serves as the main antagonist of the sixth and seventh books. In the sixth book, Melvin debuts his latest invention, the Combine-o-Tron 2000, and showcases it to his classmates by combining his pet hamster Sulu with a robotic hamster body. He tries to get the newly-transformed bionic hamster to showcase his powers, but when Sulu refuses, Melvin threatens Sulu with violence, resulting in Sulu beating up Melvin. Melvin leaves the school in humiliation, leaving George and Harold to adopt Sulu as their own while the other students go to try out a prank they made, the Squishy.

Tattletron 2000

The Tattletron 2000

Soon after, Melvin falls victim to the Squishy and gets the boys into detention by tattling on them by tell Principal Krupp they told everyone, including Miss Ribble, to do it. To get back at him, the duo writes a slanderous Captain Underpants comic about Melvin, much to his anger. In it, Melvin becomes mayor by being a tattletale and makes lots of rules getting people arrested. When all the jails are full, Melvin builds the Tattle-Tron 2000, a jail with robot limbs, to catch the rule breakers himself. When it reaches the school, they call for Captain Underpants to help, but he couldn't fight the robot without hurting everyone inside. He decides to pour prune juice into it so the robot would "poop" everyone out, setting them free. Once only Melvin is left, Captain Underpants fights him, sends him to Jail for Dumb Kids, and sets everyone else free. Wishing to get revenge on George and Harold for this, Melvin creates a robotic human body with the intention of becoming a bionic boy and thus the most popular student at school. However, his cat allergies trigger due to being near the family cat, and he sneezes and covers himself in his own mucus during the transformation, turning him into the Bionic Booger Boy.

What was separated from Melvin which became the Robo-Boogers.

Melvin initially enjoys the benefits of his transformation, such as being the star football and volleyball player and having his personal water fountain. However, when flu season hits, Melvin begins to behave strangely. When the class visits a tissue factory, Melvin becomes a gigantic and evil monster as a reaction to the tissues, forcing George and Harold to turn Mr. Krupp into Captain Underpants to fight him. Though Captain Underpants manages to rescue Ms. Edith Anthrope during the attack, her sloppy, wet kisses revert him back to Mr. Krupp, and Melvin devours him. Melvin then goes for George and Harold, but Sulu arrives and battles Melvin. Melvin's parents soon arrive, and under George's suggestion, recalibrate the Combine-o-Tron and restore Melvin and Mr. Krupp to normal. However, Mr. Krupp and Melvin begin to act like each other, and the remnants of the Bionic Booger Boy become Carl, Trixie, and Frankenbooger, the Robo-Boogers, and give chase to the group, destroying the Combine-o-Tron in the process.

In the seventh book, after Sulu subdues the three Robo-Boogers, George and Harold realize that Mr. Krupp and Melvin have switched brains. Mr. Krupp (now Kruppy the Kid) orders Melvin (now Mr. Melvin) to rebuild the Combine-O-Tron, but when Mr. Melvin claims the process could take six months, George suggests that Mr. Melvin build a time machine and acquire the Combine-O-Tron. Mr. Melvin, stricken with the idea, inadvertently transforms Kruppy the Kid into Captain Underpants and decides to get his original body back and gain Captain Underpants' powers. He orders George and Harold to make a comic that depicts him as cool or he will have their teachers give them 12 hours of homework every night for the next eight years.

Wonder Nerd

The Wily Wonder Nerd

The next day, Mr. Melvin instead finds yet another slanderous comic, Captain Underpants and the War of the Wily Wonder Nerd. In it, a cotton field is soaked in waste from a power plant and the cotton is made into underwear. Mrs. Sneedly buys a pair for Melvin, but it turns him into a giant. As he walks to school the next morning, he causes lots of damage because of his height, the army is no match for him and a tank lands on the gym teacher, resulting in the school calling for Captain Underpants. The hero finds that the underwear may shrink when washed, so he begs the Wonder Nerd not to dump him into the lake. Feeling sadistic, the Wonder Nerd walks into the lake to dump Captain Underpants in, but the underwear shrinks causing him to blow up like a balloon. Captain Underpants then pops him with a bird and sends him Jail for Dumb Stupid Nerds.

Mr. Melvin begrudgingly reveals his time machine, warning George and Harold of its side effects, and equips them with a mind eraser and a fake Combine-o-Tron. After some mishaps involving the librarian, Miss Singerbrains, and a pterodactyl they named Crackers, the duo retrieves the original Combine-o-Tron. Mr. Melvin tracks down Captain Underpants and gets their brains back in their original bodies. Meanwhile, the Robo-Boogers arrive at Uranus, latch on to a spaceship that was examining Uranus, and return to Earth. Captain Underpants, back in his original body, attempts to help, but finds that Melvin now has his powers. Melvin refuses to help unless George and Harold change the comic they wrote about him.

The trio destroy the Robo-Boogers with healthy oranges filled with Vitamin C, with Captain Underpants using a Squishy to finish off Trixie and Frankenbooger. They are questioned by Eyewitness Crew, but Melvin dubs himself "Big Melvin" and begins to claim responsibility for subduing the Robo-Boogers. George and Harold reacquire the Combine-o-Tron and restore Captain Underpants's superpowers. A defeated Melvin is confronted and chased into the sunset by an angry mob of people that Captain Underpants had disrupted while in Melvin's body.

As revealed in the eleventh book, shortly after the events of the eighth book, the Turbo Toilet 2000 returns from Uranus and disturbs Melvin's experiments. Melvin finds one of Mr. Krupp's toenails, uses it to acquire Captain Underpants's abilities (since the toenail has Mr. Krupp's DNA), and subdues the Turbo Toilet 2000. Once again known as Big Melvin, he basks in the fame of being a superhero, but he eventually becomes tired because citizens were calling him for minute problems. He tracks down George and Harold using a GPS in Sulu's robotic body, leading to him finding them in the tenth book and sending them back to the present in the eleventh book. He then warns them of the Toilet's return before disappearing. Melvin can be seen watching the teachers go crazy.

In the twelfth book, Melvin was sitting next to Yesterday George and Harold who had been sprayed to behave Melvin admitted he was starting to like them now. It's unknown if Melvin was sprayed but if he was it's assumed after the story ended the effects wore off as they only lasted 24 hours. In a Dog-man book, Melvin and Mr. Krupp end up chasing George and Harold who win an award.

In the feature film[]

Melvin appears as the secondary antagonist and the sidekick of Professor Poopypants. He first appears in the classroom where tells George and Harold he told on them changing the school sign since someone has to stand up for Mr. Krupp. During the Invention Convention, he debuts many inventions, concluding with the Turbo Toilet 2000. However, things go awry when George and Harold tamper with the Turbo Toilet 2000, reprogramming it to shoot out toilet papers. However, Melvin is able to catch them in the act thanks to another invention of his, the Tattle Turtle 200 (a toy tortoise with a security nanny-camera hidden inside). In order to get "extra credit" (and payback on George and Harold), Melvin turns over the Tattle Turtle's footage to Mr. Krupp, who then decides to use it as evidence to put George and Harold in separate classes for the rest of the school year as punishment for their pranks and to annihilate their friendship. This led to the creation of the film's version of Captain Underpants.

Later, after Professor Poopypants is hired as the new science teacher, he notices that Melvin is the only student who never laughed at his silly name, and the only one who likes his hatred of laughter. After studying his brain, Poopypants discovers that Melvin's brain lacks a Haha-Guffaw-Chucklotamus, the gland that causes laughter, which is why he has no sense of humor. Upon making this discovery, Poopypants recruits Melvin to help rid the world of laughter (it is not entirely known how Poopypants convinced him to or why Melvin agreed, but a deleted scene of the film indicates it may have been that Poopypants offered him more "extra credit"). To do this, they turn the Turbo Toilet 2000 into a giant mech, fueling it with rotten leftovers from the cafeteria and equipping it with a ray gun linked to Melvin's brain that erases humor.

Poopypants and Melvin attack the school and transform all the students (except George and Harold) into humorless zombies. Captain Underpants tries to stop them, but is quickly subdued due to not having any actual superpowers. While the Turbo Toilet 2000 is busy beating up Captain Underpants, George and Harold climb on top of the robot and try to reason with Melvin to get him to stop Poopypants. Melvin simply alerts Poopypants, who eventually manages to rob George and Harold of their humor. However, Poopypants accidentally restores their sarcastic sense of humor by saying "Uranus", which was the first thing that they had laughed at together.

Meanwhile, Captain Underpants, having been swallowed whole by the Turbo Toilet 2000, gains superpowers from absorbing the chemicals inside it and defeats the Turbo Toilet 2000. As George and Harold laugh hard, the light bulb ray gun explodes because Poopypants overloaded it with power, which restores everyone's sense of humor and sending Melvin falling to the ground. before it explodes, Melvin reflects on whether to depend on his success or his survival, then yells "I choose survival!" right before the ray explodes and causes the Turbo Toilet to malfunction and start firing gigantic toilet paper rolls all over the school yard. Though Melvin survives the fall, he is then flattened by a toilet paper roll, which is then rolled across the school yard by a group of children.

It is unknown what happened to Melvin after the events of the film. It is possible he may have redeemed himself before the explosion and that the reverse-ray may have given him a sense of humour (as he smiles slightly before being hit by the toilet paper), but it is also possible that he was injured by the roll falling onto him and then irritated by the children, and therefore may still be evil and willing to return.

In the animated series[]

He serve as the secondary antagonist of the series, where he makes typical inventions that George and Harold frequently exploit to take the easy way out of their issues, despite the fact that it frequently generates the difficulty of the week. One of his most renowned creations is the Time Toad, which is employed multiple times during the series. He has a crush on Erica Wang since her intelligence is similar to his. A running gag is that he frequently comes up with insults that make no sense.

In Episode 13, Endenemys reveals that he is Melvin from the future. He fires Krupp, and expels George and Harold.

In the first episode of Season 2, Melvin and Endenemys (who has become Melvinborg) succeeded in taking over Jerome Horwitz Elementary School (which has been renamed Melvin Sneedly Elementary) and replaced all the teachers with robots.

In Episode 3 of Season 2, Melvinborg uses bee DNA to turn the teachers into a hive-mind, but he injects too much into one teacher (Ms. Ribble), turning her into Queen Zombee.

In Episode 6 of Season 2, He and Melvinborg got brainwashed by Splotch.

In the season two finale, when Melvinborg plans to kill Captain Underpants while the nanobots are inside his body, he realizes how genuinely evil he will become. He grows tired of his future self's lack of forethought and abandons the plan, causing his future self to vanish forever. The future Erica then states that this act of kindness could be the beginning of his transformation for the best.

In the third season, he accompanies the children to summer camp, but is the last to participate in the fun. During this season, he creates a comic book with George using a drawing technique heavily influenced by computers. When George convinces him to return to being closest friends with Harold, he becomes extremely upset. His intelligence is inadvertently reduced to that of a wild animal at one point. He regains his normalcy off-screen.

Throughout Season 3, he got more homicidal and violent, sometimes trying to kill George, Harold, Captain Underpants and his follow classmates, such as in "The Ludicrous Lunacy of the Loopy Laserlightmare" as his laser prison has death traps and nearly got George, Harold, Erica, Gooch, Bo, Stanley, Jessica, Dressy and Sophies killed and later trying to use the laser monster to kill George and Harold after discovering they had got out his laser dome, and in "The Shocking Showdown of the Staggering Sugamechanger", he creates a creature composed of one-third sugar, one-third trampoline, and one-third video game so that their parents won't sign them up for camp next summer and he can attend Outer Space Camp, which will place them all in danger and kill them all. but still remains as an anti-hero.

In the season 3 finale, Melvin build a machine and used it on scripted play with George’s and Harold’s classmates in costumes that made the monsters real and going to defeat the boys and Erica, Mr. Ree, Sergeant Boxers and Captain Underpants.

Melvin despises Halloween because he is lonely and allergic to candy, as shown in The Heartbreaking Havoc of the Haunting Hack-A-Ween. With Mr. Krupp, he plays a critical part in having Halloween banned. He is irritated when George and Harold make Hack-a-ween, and he is even more irritated when Gooch comes over (mostly because Gooch was paid to do so). When George and Harold urge him to go sneaking or nibbling with them, he appears eager to accept. He had, however, transformed the Hack-O-Ween balloons and a home into monsters to attack 38 minutes earlier. He assists George and Harold in saving the day, but he is let down when Halloween is revived due to his sweets allergies.

In the mini seires, He wants to uncover something wonderful in space to become a "science god" on earth. He tries to steal the Litlite ship and return it to Earth, and he later makes the initial contact with the Biglyans. He eventually gets captured by the Biglyans, but he eventually convinces them to anoint him king. He is shoved aside by the Biglyans after attempting to lead the Biglyan armada to Earth to take over. After the final fight with the Biglyans, he fled to Earth to take it over and converted all organic things into Melvin-like beings. Only for George and Harold using the Time Toad to fix it.

Trivia[]

  • Melvin is allergic to cats, as when his cat, Danderella, enters his room, he sneezes before he shoos it away.
    • Cindy and Gaylord still keep Danderella because they've had her before Melvin was even born and couldn't bear to get of her when Melvin's allergies were discovered. Of course, they couldn't have known that this decision would inadvertently lead to Robo-boogers terrorizing the planet.
  • He is also allergic to chocolate and gets a rash if he eats anything with MSG (monosodium glutamate).
  • Melvin doesn't have a sense of humor in the movie, as he doesn't laugh at all. However, in the series and books he does laugh, though in a mocking manner rather than when responding to humorous situations.
  • Melvin is depicted to have created the Turbo Toilet 2000 in the movie as originally a technologically advanced toilet before turning into a giant evil robot suit, whereas in the books George and Harold created it as a villain in their comics, even though they used something Melvin invented.
  • In book 7, when Melvin and Captain Underpants' brains are back in their own bodies, but Captain Underpants' superpowers are still in Melvin's body as Melvin plan. Melvin would not save anyone's lives from the Robo-Boogers unless he wanted George and Harold to change comic book about him and make him cool this time, which would've gotten everyone killed by the Robo-Boogers.
  • In book 8, in a universe where good and evil are swapped, Melvin is a dumb kid who does not invent. Despite this, the Turbo Toilet 2000 and Robo-Boogers are there.
  • He is mentioned in a newspaper that was about George, Harold, and Mr. Krupp's trial in book 9. It said that he laughed at them when the three are found guilty.
  • Despite being the smartest kid in school, he failed to notice that Mr. Krupp is wearing a toupee to hide his baldness problem.
  • In the book series, Melvin found out Mr. Krupp is Captain Underpants, however in the tv series and in the movie, he never found out Mr. Krupp is Captain Underpants.
  • Melvin is infatuated with hamnog, a fictitious drink inspired by eggnog, in The Xtreme Xploits of the Xplosive Xmas.
  • It may have been pointed out that the reason behind Melvin's evil nature was probably because of a bad home life, especially when it came to his parents as shown in book 6, when he told them no one in school respect his smart mind and he he will teach them all, his mom just say “That’s nice honey”, implied that his parents probably negligent and ignore him and in the tv show, that he has no friends and is lonely, especially in the halloween speical, which is one of the reasons he hated halloween.
  • It is demonstrated in The Frenzied Farts of Flabby Flabulous that Melvin was able to construct robots even as a young child.
  • He is modeled after a tattletale child that Pilkey knew from school, who has been given the alias "Michael Sneedman" to conceal his identity.
  • Unlike in the books, Melvin does not refer to the other children as being immature in the TV series. Instead, he employs distinctive epithets (such as "You unbaked bananas!") that change based on the episode.
  • The only episode of the TV show where Melvin is absent is The Disturbing Dilemma of the Dysfunctional Doppelgangers.
  • In both The Terrifying Perilous Misfortune of the T.P. Mummy and The Cunning Combat of the Covert Camoflush, he make cameo roles.
  • He has a theme song in The Epic Tales of Captain Underpants, suitably called "The Melvin Song."
  • In The Epic Tales of Captain Underpants in Space!, he exhibits periods of stupidity despite having a high IQ, such as the fact that he consistently falls for the Biglyans' traps even while George and Harold don't.
  • In the TV show, his refrigerator actually starts up by itself. When Melvin informs the police that he always pursues it, they don't believe him.
