Synopsis for Harold Hutchins from Captain Underpants.
==History==
===Role in the books===
==== Early Life ====
Harold had a not-so-great life as a kid, his dad left, he was severely picked at school by Kipper and his gang and more. However, one time, George caught Kipper Krupp and The Gas Station Guy bullying Harold. So, George changed the sign " Free Brake Inspection " to " Free Bra inspection ". 
The Gas Station Guy was about to get George, until a couple of angry women came and beat im' up. George turned up and saw the kids that were snapping Harold's crayons and tore up Harold's Drawings. George shouted them to leave him alone, but Kipper laughed and told his gang to get him. But George got his Tie and said "I am gonna to Indiana Jones ya!" . 
He manages to beat up them, George threatens them to never mess with him again alongside Harold. Where Kipper yells " U-U-Uncle Benny! " and Krupp comes. George and Harold come to the the detention office. And Harold draws pictures of Heroes vs Monsters, George asks what's Captain Underpants'/monster's name. Harold says he dosen't have a name because it's just a drawing, not really a story. Harold asks if he wants to draw, George declines since he a writer. Harold gave him some Papers for him to write in, and George writes..." The Adventures of Dog-Man ". And ever since that day, George and Harold become friends and " Treehouse COMIX inc. " is born.
This made the two become fast friends. However, they couldn't take Kipper's tyrannical rule any longer, so they decided to constantly prank him, causing him to be embarrassed in front of his friends. However, Kipper eventually catches on to the setting and the next day and him and his gang steal the pizza that George and Harold had bought for the kindergartners to torture them even more. Enraged, the two friends retaliate with another big prank on the bullies. First, they fill the four bullies' lockers with shaving cream to pass it off as ectoplasmic spirit juice. While it initially worked, Mr. Krupp points out that the "ectoplasm" was apparently sprayed through the holes in the doors. Infuriated and tired of the anonymous pranks, Kipper and his friends begin torturing the kindergartners to answer them, even stealing more pizzas that George and Harold actually counted on to steal from them because they ordered them to get double the ghost chili peppers (Piqua Pizza Palace's the hottest chili peppers) that cause the bullies' tongues to burn off completely, resulting in them being sent to the nurse's office. George and Harold end up creating a comic book that tells the story of Wedgie Magee and the sign of his curse, all matching their pranks. After Kipper and his gang "see" the ghost (George on stilts, wearing giant pants), they run outside in terror during a severe thunderstorm and power outage.
On Monday morning, Kipper gives a $5 bill to Donny Shoemeyer and promises to return all the money he stole from him. Elsewhere, Kipper's friends give money to kindergartens and do good deeds for them. Kipper and his friends eventually returned all the money they stole and never picked anyone again. George and Harold later called off Wedgie Magee's vengeful wrath after they were certain that their enemies had indeed been reformed. The boys dedicated their lives to pranks and creating comics. 
====Present====
In The Adventures of Captain Underpants, George and Harold remained friends in the the fourth grade, and continued their usual pranks and comic creation, in this case, the creation of what would be the highlight of the rest of their lives; Captain Underpants. Mr. Krupp, sick of their pranks, plans to sabotage their pranking spree so they would become obedient students. He gets video footage of them setting up pranks that result in the school football team losing a big game. He informs them of his victory, and blackmails them with a ridiculous list of demands, promising to give the tape to the football team if they don't comply. George and Harold are forced to be slaves to Mr. Krupp and be completely obedient to him.
Sick of being a slave, George orders a 3D Hypno-Ring, and he and Harold hypnotize Mr. Krupp. After retrieving the evidence and replacing it with a video belonging to Harold's sister, they abuse the powers of the Hypno-Ring and get revenge on Mr. Krupp. They use the hypnosis to make Mr. Krupp believe he is a chicken, then a monkey, then Captain Underpants. This ultimately backfires when Mr. Krupp jumps out the window to fight crime. The resulting mayhem led to encounters with two robots and a small mad scientist in a diaper. The two then revert Captain Underpants back into Mr. Krupp by pouring water onto his head, but the effect of transformation by the snap of fingers remains.
In Captain Underpants and the Attack of the Talking Toilets, George and Harold must see a poster advertising the school's annual Invention Convention, but they discover they are banned from attending or participating due to their previous prank on last year's convention. The two then decide to sabotage the inventions on display, except for Melvin Sneedly's invention the PATSY 2000 (which could convert 2D pictures to 3D life forms), in exchange for Melvin not tattling. However, the resulting chaos leads Melvin to break his promise and snitch on them, resulting in the two to be put in detention.
After creating another comic book, the two decide to print copies to sell on the playground. But seeing that teachers were in the office, they decide to use the PATSY 2000, thinking it is actually a simple copy machine. However, the PATSY 2000 brings the Talking Toilets from the comic's cover to life, bent on eating everyone in their sights. Mr. Krupp then spots them exiting the study hall, and promptly suspends them. However, the teacher's careless abuse releases the Talking Toilets, who eats them all up except for George, Harold, and Mr. Krupp (who becomes Captain Underpants once more). After the useless act of shooting underpants into the Toilets' mouths, the three heroes feed the man eaters cafeteria food, causing them to vomit out the teachers and pass out.
Unfortunately, the Turbo Toilet 2000 appears and eats Captain Underpants. Locking themselves in the school, George and Harold hastily create a Robo-Plunger and bring him to life, successfully beating the behemoth. After clearing their suspension with the revived Mr. Krupp, George and Harold command the robot to repair the school and take all the toilets to Uranus. After the ordeal, George and Harold become Principal for a Day, and launch a festival on the playground as the teachers and Melvin are forced to repeatedly write sentences on a chalkboard.
In Captain Underpants and the Invasion of the Incredibly Naughty Cafeteria Ladies from Outer Space (and the Subsequent Assault of the Equally Evil Lunchroom Zombie Nerds), After seeing a soda volcano in science, George and Harold decide to prank the Cafeteria Ladies with the same idea. They create a fake birthday cupcake recipe from Mr. Krupp that contains baking soda and vinegar and give it to the lunch ladies. Instead of making a batch of cupcakes just for Mr. Krupp, the Lunch Ladies decide to make cupcakes for the whole school and make 100 batches of the recipe at once. This results in a large wave of green goop filling the entire school. George and Harold deny involvement, as they did not intend for the Lunch Ladies to make that large a batch.
Fed up with George and Harold's pranks, the cafeteria ladies quit. Almost immediately, three strangely reptilian Cafeteria Ladies apply for the job, and Mr. Krupp takes away George and Harold's lunch privileges by making them eat with him. After disgusting and sickening Mr. Krupp with their strange mixture of sandwiches (such as peanut butter and gummy worms), George and Harold sneak out only to discover that the students eating lunch have been transformed into evil Zombie Nerds. Now sitting between a window and an island counter they grab the mysterious substance and dump the contents out the window and on to an oblivious dandelion. Shortly after, the strange reptilians are forced to grab another container of the substance, located in their UFO on the main campus building. Inside they find some Anti-Evil Zombie Nerd Juice, some Ultra Nasty Self-Destruct Juice, and some Extra Strength Super-Power Juice. The aliens however then suddenly come in and lock them in a cell, but luckily George and Harold hid the juice cartons they found behind their backs. Zorx starts the ship up so that the ship is hovering a few feet above the school. Klax then takes some Super Evil Rapid Growth Juice from the fridge so that the aliens can put the juice in the spray gun which will shower the juice over the zombie nerds. While laughing victoriously at their apparent victory, George and Harold swap the labels of the juice cartons and the signs of the spray gun and fuel tank, so the aliens pour self destruct juice into the fuel tank instead of rapid growth juice into the spray gun, which makes the spaceship explode.
Captain Underpants jumps off the spaceship with George and Harold, claiming that he can use toilet paper to swing onto the ground as he proclaimed that he did it in his last comic book George and Harold wrote earlier. Of course, the toilet paper breaks because it cannot support their weight, so the trio start falling to the ground fast, but Captain Underpants' cape then acts like a parachute, making them fall more slowly and gently to the ground. However, they, unfortunately, end up landing near the mutated dandelion, who then grabs Captain Underpants down with its teeth and knocks George and Harold onto the school roof. George and Harold give Captain Underpants some of the superpower juice to help him break free and defeat the dandelion. The juice gave him the ability of enhanced strength and the ability to fly. After the dandelion is defeated, George wonders how to get the zombie nerds back to normal. Harold suggests using the anti-evil zombie nerd juice to fix the problem. George notes that he was hoping for something more dramatic, but as they are running out of pages they should do it. Mixing anti-evil zombie nerd juice with root beer and having all the zombies drink it, they turn everyone back to normal, but not before getting the Captain to dress back up like Mr. Krupp and pouring water on his head.
Something has changed about Mr. Krupp though because he drank the super-power juice, so now whenever he becomes Captain Underpants, he can fly and use other superpowers, thus making it harder for George and Harold to keep tabs on him (evident after a girl snaps her fingers in front of Mr. Krupp while she was listening to music). Instead of Harold and George looking out the window witnessing Captain Underpants running into the city. They are outside on his cape clinging on as he flies into the city instead.
In Captain Underpants and the Perilous Plot of Professor Poopypants, George and Harold are forbidden to go on the school field trip, so they have to stay behind and clean the teacher's lounge. To get back at the teachers, they rig the place so they are covered in Styrofoam packing peanuts. Mr. Fyde sees this and decides to quit, thinking he's going crazy.
Sometime later, George and Harold get a new science teacher named Professor Poopypants and everyone laughs at his ridiculous name. The next day, Professor Poopypants builds a new robotic gerbil jogger and everyone is impressed, at least until George and Harold ruin everything and cause him to be laughed at again. Worse, they make a comic book about him as an evil villain.
Professor Poopypants shrinks the school and forces the entire world to change their names into silly names or they'll be shrunk out of existence. In George and Harold's cases, they are renamed "Fluffy and Cheeseball". Fluffy and Cheeseball summon Captain Underpants and have him grab the professor's growth machine. Unfortunately, Poopypants shrinks Captain Underpants and the machine, so Fluffy decides to use the growth machine to make Captain Underpants as big as a giant. But he accidentally makes Cheesball's hand big as well.
After a big battle in Flip-o-Rama, Captain Underpants defeats Poopypants and the boys return the school and everyone in it to their normal sizes as well as give them back their old names. When Poopypants is arrested, George and Harold question why he didn't change his name instead of forcing everyone else to change theirs.
After receiving a letter from Poopypants (who now goes by Tippy Tinkletrousers), George and Harold realize that they shouldn't have made fun of Tippy in the first place, then, he wouldn't have turned evil.
In Captain Underpants and the Wrath of the Wicked Wedgie Woman, When Ms. Ribble announces that she will be retiring, the boys decide to make a comic book about her. When she disapproves, she sends them to the principal's office. At that same time, they trick Mr. Krupp into signing a card for them, which they later pass off as a marriage proposal. The following week, the wedding arrives and Ribble reveals that she doesn't want to marry Krupp. At first, Krupp is happy about this, but when she begins insulting him, Krupp reveals that George and Harold were behind the trick, as always. The boys run for their lives, avoiding Ribble nearly strangling them.
On Monday, Ms. Ribble tells the boys that she has changed their grades so that they will become left back as punishment for their little stunt (including a made-up grade called a "G"). To stop Ms. Ribble, the boys dig up their Hypno-Ring to trick her into changing their grades back to normal, but also tell her she won't think that she is Wedgie Woman, the villain from their latest comic book. Little do they know that the Hypno-Rings cause women to do the opposite of what they are commanded to do. That night, Ms. Ribble (who now thinks she's Wedgie Woman) reads George and Harold's comic books and attacks them at the treehouse for some information. Just then, some Super Power Juice spills down on Wedgie Woman's hair and it causes her hair to operate like arms. She takes George and Harold back to her house to build robot duplicates of them to chase Captain Underpants.
George and Harold escape Wedgie Woman’s house and sees Captain Underpants hanging from a pole because the robots sprayed him with starch. The boys tries to inform him that he’s not really weak, but he won’t believe them. When they can’t buy any fabric softener, they then draws a short comic story telling his secret origin and that starch can’t hurt him. This makes Captain Underpants confident again and he defeats Wedgie Woman’s robots. George then tricks Wedgie Woman into spraying hair remover, which takes away her magic beehive (along with the boy's hair). Using the Hypno-Ring, the boys erase Wedgie Woman’s memories of her evil double identity, the wedding, changing George and Harold’s grades, and planning to retire. They also make her into a kinder and better person, which makes their class a better place for learning.
In Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy, Part 1: The Night of the Nasty Nostril Nuggets, George and Harold create a new fad called, "Squishies", where you put two packets of ketchup underneath a toilet seat and it squirts people's legs. Melvin doesn't care and wants to show off his newest invention, the Combine-O-Tron 2000, which emerges people's molecules together. 
He uses a hamster named Sulu and a bionic super hamster robot. When Sulu won't obey him, he threatens to smack him with a paddle, but Sulu spanks him back using his powers. Melvin runs off and disowns the hamster, so George and Harold adopt him. Melvin tells on George and Harold for getting everyone’s legs covered in ketchup and Krupp sends them to detention. To get revenge, the boys make a comic book depicting Melvin as an evil villain.
The very next day, George and Harold brings Sulu back to class to do some neat tricks, but then Melvin arrives and has been turned into a snot monster. He explains that he tried to combine himself with a robot, but then sneezed at the last second and now he’s become a monster. George asks him how long it will take to change him back, Melvin replies that it will take about six months. During his time as the Bionic Booger Boy, Melvin starts grossing everyone out and getting snot all over the place.
Sometime later, Krupp and Miss Anthrope take the class to a tissue factory, which causes Melvin to grow to a large size and rampage through the city. Miss Anthrope threatens to send him to detention, only for Melvin to snatch her. The boys summon Captain Underpants and he saves her. When the drool from a disgusting sloppy kiss changes Captain Underpants back to Krupp, Melvin swallows him whole. Just when all hope is lost, Sulu saves the boys and defeats Melvin.
Melvin’s parents arrive to inform everyone that they’re trying to make a machine to change Melvin back to normal, but George suggests they just switch the batteries in the Combine-O-Tron, to which Mr. Sneedly takes credit for. When Krupp and Melvin are returned to normal, they begin acting strangely. Just then, three Robo-Boogers come to life, smash the Combine-O-Tron and chase the protagonists.
In Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy, Part 2: The Revenge of the Ridiculous Robo-Boogers, After Sulu blasts the Robo-Boogers into space, the four walk back to school. They then realize that the Combine-O-Tron must have caused Mr. Krupp and Melvin to switch bodies. Melvin (now called "Mr. Melvin") explains that it will take six months to build another Combine-O-Tron, since the old one got smashed. George suggests that Mr. Melvin could build a time machine to go back into time and recover the machine before it got smashed, though Melvin takes credit for it. When Melvin snaps his fingers, Mr. Krupp (now called Kruppy The Kid) turns into Captain Underpants (now called Captain Kruppy the Underpants Kid) and flies out of the window.
The boys explains the whole thing to Mr. Melvin, who decides to use his "power" to blackmail George and Harold into making a comic about him destroying Captain Underpants and how he plots to transfer Captain Underpants' powers into his body when they switch back. If they don't comply, they will have extra homework for the rest of their academic careers.
The boys then show Mr. Melvin the comic book they made, which does the opposite of what he told them to do. He then gives them detailed instructions on what to do when they get to the past. He also warns them not to use the time machine for two days and give it a day to cool off. Otherwise, they will end up in an alternate dimension, but the boys don't listen and change the letters on a sign.
The boys end up in the past, where they find their past selves. They manage in switch the Combine-O-Tron with a fake one and erase Mr. Sneedly's memories of seeing them. Just then, Miss Singerbrains grabs the inventions and decides to take them to the police, mistaking them for dangerous weapons. When George and Harold can't catch up to her, they borrow a pterodactyl from prehistory and use her to catch up Singerbrains. Harold grows attached to the pterodactyl and decides to name her, "Crackers", even though George tells Harold that they are not keeping her. While George looks after Miss Singerbrains, he orders Harold to take Crackers back to her natural time period. Little does he know that Harold went against his orders and took her back to the treehouse instead. George and Harold make it back to the present and reunite with Mr. Melvin and Captain Kruppy the Underpants Kid. The two switch their bodies back to normal, but Melvin has taken away all of Captain Underpants' superpowers and mocks him for it. When George and Harold see that the Robo-Boogers have returned and are terrorizing the city, they try to tell Melvin to go do something, but he refuses unless they write a new comic about him. 
Since Melvin won't listen to reason, the boys decide to stop the Robo-Boogers themselves. They discover that Vitamin C is their true weakness, so Captain Underpants starts irritating them to anger them and make them squirt orange juice into their faces, destroying them. The news arrives and Melvin tries to take credit, only for George and Harold to put Captain Underpants' powers back into their rightful place. Melvin is then chased by some civilians that Captain Underpants annoyed while he was in Melvin's body. George and Harold go home only to find out that Harold took Crackers back to the treehouse. George tells Harold they can let her stay for the night, but they are taking her back the next day. The very next day, George and Harold take Sulu and Crackers back to the time machine to return Crackers home. Harold doesn't want to because Melvin said they should give the machine a day to cool off, but George doesn't listen and they use the time machine anyway, causing some sort of meltdown to occur. 
In Captain Underpants and the Preposterous Plight of the Purple Potty People, George, Harold, Crackers, and Sulu find themselves in an alternate universe where everything is opposite; the teachers are nice, the school has tasty food, Melvin is dumb, and their enemies have become good guys. When they try to go home, they find out that Sulu and Crackers have been kidnapped by their alternate dimension counterparts. They find a comic book telling the origin of their twins' evil minion, Captain Blunderpants, who apparently has turned their treehouse into a swinging bachelor pad by robbing stores. 
George and Harold go over to their evil twins' treehouse, where they see that Crackers and Sulu are being hypnotized into being wicked slaves. However, since Crackers is a girl (unbeknownest to the boys), it doesn't work on her and she flies them back to the time machine. When they get into the Purple Potty, their evil twins, Sulu and Nice Mr. Krupp follow them back to their world. They make it back to their own world and try to go back to the time machine to save Sulu, but George's father comes along and reminds them that it is Grandparents Day and they should come and have some dinner with their families. 
They hand George's grandma and Harold's grandpa a comic book they made for them, but refuse to sit down and eat, leading to an argument with George's dad. While arguing, George and Harold's grandparents drink the super power juice while reading the comic books. Just then, George and Harold see their evil twins making Sulu grow large with the Goosy Grow 4000 and making him rampage through the town. When the boys see that the super power juice is gone, they go down to Mr. Krupp's house to turn him into Captain Underpants. Captain Underpants defeats Sulu and the boys manage to change Captain Blunderpants back into a nice principal. Just then, there is a rainstorm and Captain Underpants changes back into Krupp and Nice Krupp changes back into Blunderpants. 
Blunderpants then starts attacking George and Harold when all of a sudden, George's grandma and Harold's grandpa arrive and use their new superpowers to defeat Blunderpants, while George and Harold use the Shrinky Pig to shrink their evil doubles. The boys return Sulu back to normal and send their evil twins back to their own dimension. Unfortunately, the cops arrive and arrest them for robbing the bank (it was really their evil twins).
In Captain Underpants and the Terrifying Re-Turn of Tippy Tinkletrousers, After getting arrested, George, Harold, and Krupp are put on trial for nearly an entire year and are found guilty. During their time in juvie, George and Harold actually enjoy it because they have a music teacher and an art teacher. When Tippy Tinkletrousers breaks out of jail, he nabs George and Harold to get information on Captain Underpants out of them. Thinking quickly, the boys snap their fingers and change Mr. Krupp into Captain Underpants. When Captain Underpants causes Tippy to freeze his robotic pants.
Realizing that the Captain is too powerful for him to beat, the Professor decides to go back in time five years ago to escape from him. Tippy does so and successfully escapes from Captain Underpants. When Kipper Krupp and his friends encounter Tippy Tinkletrousers, who had traveled back in time to the point where the bullies had just fallen for the ghost prank. Upon seeing Tippy appear before them (as they assumed he and his robo-pants were Wedgie Magee's ghost due to it being dark outside), the bullies go insane and start to do nonsensical things, such as eating dirt. Kipper and his friends eventually get sent to the Piqua Valley Home for the Reality-Challenged, where the former science teacher of the Jerome Horwitz Elementary School, Morty Fyde, resides in the future. This in turn got Benjamin fired as that made the authorities assume he was responsible for Kipper and his friends' breakdown.
When Tippy causes Mr. Krupp to lose his job and prevent him from becoming Captain Underpants, it cause Dr. Diaper to blow up the moon and the aliens to succeed in turning everyone into zombie nerds. Tippy then goes back in time again to undo his mistake.
In Captain Underpants and the Revolting Revenge of the Radioactive Robo-Boxers, After Tippy fix his mistake, the boys travel back in time with their pets, but accidentally take Mr. Krupp with them. Big Tippy sends his smaller self back ten minutes to find where, then back there then, where the small ones zap themselves back and steal the Goosy-Grow 4000, which turns Tiny Tippy extremely massive. When Big Tippy attempts to use his nuclear bomb to kill Captain Underpants, Supa Mega Tippy zaps himself back in time (with his twin) and kicks Big Tippy and his bomb away into the Gulf of Mexico. When the bomb explodes, it blows a huge crater and kills the dinosaurs.
The five protagonists and their captor then travel to the African savannas where the boys and their pets gain the trust of some cavemen who inhabit the surrounding jungles. The cavemen are taught English through drawings and subsequently, the boys make the world's first comic book (which involves drawings of traps working on Supa Mega Tippy). The Neanderthals, inspired by the book, then set traps for Tippy and defeat him. He then sets off his freeze ray (which has been tampered with by his younger twin so that it could not be turned off), and the Goosy-Grow 4000 enlarges the ice which appears to make Crackers' condition deteriorate and causes the Ice Age (and freezing Supa Mega Tippy himself).
George, Harold, Crackers, Sulu, and the cavemen run over to Mr. Krupp to free him. However, the ice encases everyone and freezes them. When all hope seems lost, Tippy, now 200 feet tall, grabs everyone with his robotic hands. Then, George and Harold snap their fingers again, turning Mr. Krupp back into Captain Underpants. Captain Underpants rips off Tippy's robotic pants, leaving him standing there in his boxers.
Using the pants as a net, Captain Underpants, George, Harold, Crackers, and Sulu take the cave people over to France, giving them a new place to live. When they return to Tippy, asking for a ride back to the future, Tippy squirts water from the water bottle at Captain Underpants' face, turning him back into Mr. Krupp. While they are all falling, Crackers is getting sicker and sicker for some strange reason. Tippy then captures the five with his hand, and they all get ready to go back home. George and Harold both vow to start acting more mature and take their classes seriously as they go forward in time.
George and Harold are then transported to the future by Slightly Younger Tiny Tippy, who is now gigantic, thanks to the Goosy-Grow 4000. But it turns out they are now teachers at Jerome Horwitz Elementary, and Mr. Krupp is an old man. After getting rid of their evil future selves by vowing never to take life seriously, they snap their fingers, turning both Mr. Krupps into Captain Underpants, and they beat up Slightly Younger Tiny Tippy, who afterward attempts to use his nuclear bomb to blow up the entire galaxy. 
After that, Crackers and Sulu decide to save the entire galaxy by sending Slightly Younger Tiny Tippy and themselves back to the time before the universe existed (13.7 billion years ago). The three are then killed by Slightly Younger Tiny Tippy's giant nuclear bomb and the universe is formed. It also turns out that Crackers had laid a brood of eggs (revealing Crackers to have been a female) and George, Harold, and the younger Captain Underpants all decide to take care of them. Suddenly, George's and Harold's nemesis, Melvin, in a giant Robo-Squid, appears and captures George, Harold, Captain Underpants, and Crackers' eggs, taking them back to the past.
In Captain Underpants and the Tyrannical Retaliation of the Turbo Toilet 2000, After returning Captain Underpants home, George and Harold back home, before Melvin warns them of bad to come. After turning Captain Underpants back into Mr. Krupp, the boys try to nap as they haven't slept in 30 hours. Unfortunately, it turns out that while running from Tippy Tinkletrousers in Book 10, they ended up missing a full school day, and they tried to explain everything to their parents but they didn't believe them, and as a punishment, they are forced to do five hours of yard work. Upon finishing, George then realizes they have a test day tomorrow, prompting them to stay up all night to study. In the morning, they fall asleep in their treehouse, causing them to miss their tests. The next day, Mr. Krupp gleefully reveals that this was actually "Super Secret Test Day" and that the boys got all zeroes on their tests. He also reveals that makeup tests are prohibited and the final exams have been canceled, meaning final grades have already been calculated; while George barely gets a passing grade, Harold fails, causing him to repeat the fourth grade, and separating the two boys in school, much to the glee of the teachers. 
George convinces Harold to travel back with the suit to take their tests, but they now have duplicates from that point. After explaining to their past selves what happened, George opts for the two pairs to switch off every other day. As the Yesterday versions go to their houses that Sunday night, the original boys have a sleepover at their treehouse, watching movies while eating pizza and soda. The next morning at school, the original boys go to school to make copies of their latest comic but are caught by Miss Anthrope. 
George tries to convince her that she is dreaming, but Yesterday George and Harold suddenly arrive at the office, making her realize she has seen two versions of the boys. Fully convinced she is dreaming, she strips naked. The Yesterday versions warn the boys to stay away from school, but the original boys pull some pranks that make all the school's teachers similarly crazy. When Mr. Krupp sees that all teachers are naked, and the two Georges and Harolds, he is speechless and starts repeatedly saying "Buh-buh-bubba-bobba-hob-hubba-hubba-wah-wah." The police eventually come, and one of the teachers pants one the officers, causing all the teachers to be arrested for indecent exposure, reckless endangerment, and pantsing the police officer, while Mr. Krupp is sent to an insane asylum.
Two weeks have passed, the Turbo Toilet 2000 flies down to Earth, while George and Harold, disguised as Talking Toilets, convince the Turbo Toilet 2000 to break down the asylum wall. Over the intercom, George snaps his fingers, turning Mr. Krupp into Captain Underpants, who fights the Turbo Toilet 2000 and wins, but the Turbo Toilet 2000's giant tears of pain fall on his head. Mr. Krupp directs the Turbo Toilet 2000 to George and Harold's treehouse, but the Turbo Toilet 2000 swallows him whole. While shaking the treehouse to get the Yesterday George and Harolds out, Crackers' eggs get cracked on the floor. The Yesterdays discover they are pterodactyl-hamsters, who smash the Turbo Toilet 2000 while rescuing the Yesterdays, after which Mr. Krupp is arrested as a dreaming loon. The four boys regroup and begin to declare this as a happy ending. However, George points out that while the day has been saved, there were a lot of loose ends in the story (the city being destroyed, the school staff being arrested, there being four Georges and Harolds, and the pterodactyl-hamster hybrids having thought that the Georges and Harolds were their parents). The boys then realize there's one final sequel.
In Captain Underpants and the Sensational Saga of Sir Stinks-A-Lot, Mr. Meaner became smart and takes control of an abandoned factory, and he makes a strange substance with sweaty gym socks called the Rid-o-Kid 2000. Yesterday George and Harold are told to go to his office, where he sprays them with Rid-o-Kid 2000, turning them into robot-like slaves. The other teachers are amazed at their behavior, though the other George and Harold are not, and they get sicker because of excessive homework. They see a commercial for the “Rid-o-Kid 2000” and disguise themselves as adults, making the children do fun activities for the teachers. The teachers call in Mr. Meaner, who, enraged at what he sees, dons his "Kid Killer 2000", now a robotic exoskeleton suit.
Deciding to seek help from adults they can trust, George and Harold go to their parents, only to find that they are happy with how their children have changed. Feeling heartbroken, they go to braniac Melvin Sneevly's house to find his Robo-Squid, then travel forward in time to find the older versions of Yesterday George and Harold, now famous graphic novel writers, and their families, with whom they are also disappointed. The older Yesterday and younger Today versions of George and Harold travel back in time and George and Harold stay in the treehouse while their future selves save the day.
Things are back to the way they were, and as young Today George and Harold return their older Yesterday counterparts to their own time, they find that Mr. Krupp's hypnosis effects have indeed worn off. Aside from Harold's initial confusion; he, George, and their older counterparts do not seem to care in the slightest. They decide, given there are a George and Harold to cover for them, they will use Melvin's time machine to find their pets Crackers and Sulu. 
It is unknown what happened to the present-younger versions of George and Harold after they went back in time in order to save Crackers and Sulu so that they could meet Orlando, Tony and Dawn. At the beginning of Chapter 4, the book mentions that there exists an ever-expanding multiverse, so perhaps present George and Harold, along with Crackers, Sulu and their offspring stayed in their present timeline after being saved, somehow got lost in the space-time continuum after trying to go back to the timeline where Yesterday George and Harold reside, or they got stuck in a certain timeline after their time-machine possibly broke. If any of these scenarios are the case, that might explain why they never revisited the timeline Yesterday George and Harold live in, who would later grow up to be the Adult George and Harold featured in the book.

George Beard and Harold Hutchins are two fourth-grade friends and next-door neighbors who often bring joy to their school, Jerome Horwitz Elementary School, by excessively pranking the staff at the school, especially their cruel principal, Mr. Benjamin "Benny" Krupp, which puts them at odds with him. The duo also creates comic books about a superhero named Captain Underpants, a character who has superpowers yet merely wears underwear and a cape. They sell these to their schoolmates through a comic company called "Treehouse Comix Inc.", located in their treehouse. 
George and Harold's pranks come to an apparent end when they are caught tampering with a toilet invention, the Turbo Toilet 2000, made by their tattletale classmate, Melvin Sneedly. Mr. Krupp decides to put the boys in separate classes, believing that he can end their friendship with it.
To prevent this, George hypnotizes Mr. Krupp with a "3-D Hypno-Ring" he received out of a cereal box, the boys notice that Mr. Krupp bears a resemblance to Captain Underpants and command him to be so. The boys soon learn the severity of this when Captain Underpants begins causing trouble around Piqua and thus decide to take him to their treehouse. There, they discover that they can turn Captain Underpants back into Mr. Krupp by splashing water on him and back into Captain Underpants by snapping their fingers. 
Realizing that Mr. Krupp will continue trying to separate them, they decide to settle with Captain Underpants yet insist that he be dressed up as Mr. Krupp under the pretense of a "secret identity", to which Captain Underpants agrees. His sudden personality change even manages to attract the attention and affection of the school's shy lunch lady, Edith.
Just when George and Harold believe that their troubles have ended, an odd scientist named Professor Pee-Pee Diarrheastein Poopypants Esq. visits Jerome Horwitz Elementary School, whom Captain Underpants (still disguised as Mr. Krupp) hires to be the new science teacher, but George and Harold are suspicious due to his short-tempered and violent behavior. As it turns out, Poopypants is seeking to get rid of laughter altogether due to people never taking him him seriously for years because of his name.
With Captain Underpants as the principal, the school is a more lively place, with a fair being set up in the yard. However, a rainstorm occurs and Captain Underpants turns back into Mr. Krupp, who finally finishes the paperwork to put George and Harold into separate classes. Meanwhile, Poopypants recruits Melvin into his plan, as he has no sense of humor and does not find his name funny. 
Soon, Poopypants tries to take over the town with a giant version of Melvin's Turbo Toilet 2000, fueled by the school cafeteria's toxic leftovers left out by Edith and uses Melvin's brain as the power source to a zombie-ray to turn the children into dull and humorless zombies. 
Captain Underpants tries to stop them, but due to having no actual superpowers, he's effortlessly defeated and thrown into the toxic pool. George and Harold are captured and turned into zombies but are able to escape when their laughter from a joke that made them friends in kindergarten overloads the zombie-ray, which damages the Turbo Toilet 2000's computer and returns the kids to normal. Upon consuming the toxic leftovers, Captain Underpants acquires superpowers and, with George and Harold's help, defeats and shrinks Poopypants, who escapes on a bee shortly thereafter.
Knowing that they can't control Captain Underpants forever, George and Harold destroy the Hypno Ring in order to permanently change him back into Mr. Krupp. Feeling that Mr. Krupp would be a lot nicer if he had friends, the boys set him and Edith up on a date, making Mr. Krupp have a change of heart and return the comics he confiscated from George and Harold. However, the toxic waste from the Turbo Toilet 2000 transforms all the toilets at a scrap yard into an army of Talking Toilets, which attack the restaurant where Mr. Krupp and Edith are dining. Upon snapping his fingers accidentally, Mr. Krupp once again becomes Captain Underpants, carrying George and Harold away to help them fight the Toilets to Edith's surprise and admiration.
In a mid-credits scene, George and Harold realize that Mr. Krupp's secretary Miss Anthrope, whom they put on the phone via a false competition for $1 billion, has been on the phone for the entire film, prompting them to shut off the call to her dismay.
===Role in the TV Series===
Harold resembles the character portrayed in the novels and film. Despite being his catchphrase, "So Good" is frequently appropriated by other characters. However, he becomes irritated only when Melvin does it. Like his book counterpart, he and George accidentally create or turn someone into a supervillain that nearly took over the world or sometimes destroy it. They usually have Captain Underpants to help them. While in some episodes the boys have their friends form the school which are Erica Wang, Dressy Killman, Bo Hweemuth, Steve "Gooch" Yamaguchi, Stanley Peet, Jessica Gordon and the Sophies to help them, and other heroes like Mr. Ree and Sergeant Boxers.
It is disclosed during the episode “The Flustering Mindless Woe of the Flushable Memory Wipes” that he enjoys watching Dr. Blame (an obvious parody of Dr. Phil), but he pretends that his mother watches it.
Harold learns during the Halloween special that his mother harbors an intense affection for Mr. Meaner. This revelation elicits a prolonged period of distressing silence from him.
