Gregory "Greg" Heffley is 11 years old in the first novel. Greg's actions can be antagonistic at times, including terrorizing kids, trying to steal money from a church collection basket, lying in confession, picking on other students, playing pranks on his best friend, selling falsely advertised "fitness water," and praying for bad stuff to happen to others. He also is a very bad friend. However, he also demonstrates a degree of kindness in some of his actions. He helps his brother with his homework, gets his friend a date for a dance, and forgives his friends.
Rowley Jefferson is Greg's best friend. In the first book, Rowley is 11 years old and an antagonist in Greg's point of view while technically in a third-person view, Greg is the antagonist and Rowley is the protagonist. At the end of Diary of a Wimpy Kid: The Third Wheel, Rowley begins dating Abigail Brown, a girl who was originally Greg's date for the Valentine's Day dance. This plot continues in Diary of a Wimpy Kid: Hard Luck, where he ditches Greg for his new girlfriend Abigail. At the end of the book, the couple breaks up and he becomes friends with Greg again.
Rowley has what Greg considers strange interests for his age and gender, such as loving a singer for "six-year-old girls" named Joshie and action figures Greg believes are for younger kids. Rowley is also the owner of the comic strip Zoo Wee mama. Rowley thinks that Greg had nothing to do with the comic strip in the first book, a rare antagonistic move from him. He appears in all books except Diary of a Wimpy Kid: The Deep End.
Frank Heffley is Greg's overactive but well-meaning father. He is 40 years old in the first book and is interested in U.S. history, with his replica of a Civil War battlefield serving as a recurring plot point in the series. Frank is rude around Rowley, does not appreciate Greg's skill at video games, loathes heavy metal, and adolescents. He tries to toughen Greg up and threatens to send him to a military academy in The Last Straw, although ultimately this does not come to fruition, much to Greg's relief. However, Greg and Frank grow together in Dog Days, despite a brief period when Frank does not speak to Greg after almost getting arrested and going to jail.
Frank is addicted to junk food; in The Last Straw, he makes a New Year's Resolution to go on a strict diet, but Greg later catches him in the garage eating brownies. After Greg is forced to go for several days without any snacks due to a thief taking them, he eventually decides to catch the thief, and discovers that it is Frank.
Susan Heffley (known as Ann Heffley in the online version) is the mother of Manny, Gregory, and Rodrick, the wife of Frank and a homemaker. She is a loving and caring mother but can be embarrassing, bossy, hypocritical, dimwitted, overprotective, and naive. Susan seems to have a very small knowledge of kids Rodrick and Greg's age and constantly humiliates and ignores them. She constantly tries to get the family together which never works out. She and her husband Frank also show immense favoritism towards their youngest son, Manny.
Manny Heffley is Greg and Rodrick's three-year-old brother and 81 pixels high, who is constantly spoiled and pampered by his parents. Manny has many grudges like nearly killing the family by knocking out the power of the house in Cabin Fever and having tantrums when not getting things his way. It is also likely Manny knows his parents' favoritism towards him and he often takes advantage of it like making money out of the swearing rule, breaking Greg's items and getting away with it, never getting in trouble for his actions and often passing the blame towards Greg or Rodrick, etc. Despite being a spoiled three year old, Manny has proven to have more intelligence then he poses like figuring out how to sell all of Greg's items in Net Kritterz account and managed to change the password and locks out the whole family from watching TV by using the parental lock to only watch his favourite cartoons. However, Manny's strange behavior can also help the family as in the Long Haul he speaks fluent Spanish to help the family get home.
He is played by Connor and Owen Fielding in the first three films and is played by Dylan and Wyatt Walters in the Long Haul.
Rodrick is Greg's aggressive older brother and also a member of the metal band Loded Diper (Loaded Diaper). He loathes Greg and Rowley. Most of the time, they do not get along and either, usually Rodrick, gets the other in trouble. However, affection is shown to Greg in Dog Days (The movie) when he let Rodrick bring his band to celebrate his crush. Heather Hills', 16th. Rodrick is not a very intelligent person, as he makes foolish assumptions or actions and cannot spell very well.
Rodrick is portrayed by Devon Bostick in the first three films, and Charlie Wright in the fourth film.
Greg's extended family
Gramma is Susan's mother and Greg's maternal grandmother. Gramma is known to drive a car like the Heffleys'. Greg often calls her to his home as a way to avoid his dad's scoldings, since his father will not do this when she is around. Her favorite grandchild is Manny, although she denies and lies about this despite overwhelming evidence in the form of pictures on her refrigerator and many of Manny's drawings around her house. She also seems to have a passion for bingo and knitting. Gramma has a dog named Sweetheart, usually shortened to Sweetie. It has been said and shown that she overfeeds Sweetie.
Grandpa Heffley is Greg's unpredictable paternal grandfather, who is asked to babysit Rodrick and his brother in Rodrick Rules. He lives in a retirement home called Leisure Towers and enjoys playing games such as "Gutbusters" and "Rummy", which the two boys find boring. He never watches any real shows on the television; instead he constantly has his television tuned to the CCTV in the retirement home lobby, which he spends his time watching. In Old School, he moves out of Leisure Towers because the rent is too high and moves in with the Heffleys. Grandpa has a girlfriend named Darlene in the Hard Luck and broke up with her in Old School. Grandpa dates online. Grandpa eventually accumulates a large number of girlfriends online, culminating in him accidentally inviting all of them over and throwing a party with them. Greg is his favorite. Grandpa is known for preparing what he calls "Watercress Salad", a disgusting dish consisting of cold green beans and cucumbers floating in vinegar. Greg hates Watercress Salad, and Rodrick is aware of this, so he pretends that Greg loves it and puts a large helping onto his plate. It's stated that Grandpa never spent much time with Frank when he was a boy, and they seem to have a poor relationship. Grandpa once accidentally ran over Frank's dog with his car and lied to him about it (claiming that the dog ran away) before telling him many years later, expecting a laugh, and constantly criticizes Frank during his stay at the Heffleys' house. He has not been seen since Double Down, implying that he possibly moved out.
Joseph "Joe" Heffley is Frank's brother and Greg's uncle. Frank has a sibling rivalry with Joe due to his actions. When Manny started potty training, Uncle Joe told him to watch out for the "potty monster", causing him to fear using the bathroom, forcing Frank to change his diapers for a longer time. Joe's children call their uncle "Aunt Fwank", which Frank swears he told them to do on purpose. Susan thinks it's cute, though. In Dog Days, Greg mentions that he tried to make Joe convince Frank to get a dog, but that did not work out. He also mentions that Joe's dog, Killer ate most of his birthday cake.
Joe Heffley's Children
Joe Heffley has at least three children, who all appear to be a bit older than Manny, and are Greg's cousins. Their ages have not been confirmed, but it's possible they are 9, 7, and 5. Their names have also not been confirmed. They all call Frank "Aunt Fwank."
Great-Uncle Charlie is Nana's brother and Greg's great uncle. He is also Greg's "secret weapon" at Christmas, as he asks him to buy him presents that Frank have forbidden him from receiving. However, this backfires as he is usually given the wrong thing. Charlie is a bachelor and spends his spare money well. Greg says he wants to follow in his footsteps. In The Last Straw, Charlie got Greg a laundry hoop, hinting that he is tired of being Greg's secret weapon at Christmas, as the events that transpired meant that Greg effectively got a chore for Christmas.
Loretta (née Heffley)
Loretta (née Heffley) is Greg's great-aunt and the sister of Grandpa, Arthur, and Reba. She got a thank you note for some pants she gave Greg at Christmas. She appeared mainly in Rodrick Rules at the Thanksgiving dinner. She also appeared a couple of times in the Do It Yourself Book and The Ugly Truth. It is implied that Greg and Rodrick dislike her, as they fight over who has to greet her first when she visits.
Gammie Heffley is Greg's great-grandmother and the unofficial head of the Heffley family. She appears in The Ugly Truth as a major character. Since her home isn't very kid-friendly, She also has Lego building bricks that Susan bought so that her kids had something to do at her house, but, after the Legos made a mess of her home, she glued them into one solid block, returning her home to its non-kid-friendly state.. Gammie is a trickster and knows a lot because of "experience". When someone in the family is about 12 or 13 years old she gives them The Talk, which is about how kids should not be hurrying to grow up. Gammie loves having visitors for dinner. One day she bought a scratch ticket, and matched up two pictures and told all her family members that she had won a lot of money. Everyone was in a big rush to visit her. When they all arrived Frank told Gammie that to win, she had to match up three pictures. When she found this out, she did not care. She pulled a roast right out of the oven, and Greg figures she got what she wanted anyway. Gammie is the mother of Grandpa, Arthur, Reba, and Loretta Heffley.
Gammie is briefly mentioned by Greg in Cabin Fever when he says she gave a miniature carousel that held spoons from all over the world to Greg's family five or six years before.
Gammie returns in The Deep End and has a much smaller role. She asks Greg's family to take Uncle Gary's camper, which has been parked in her driveway for two years, and makes sandwiches for them to eat on their trip.
Reba (née Heffley)
Reba (née Heffley) was Greg's great-aunt. Gammie forgot to give her an invitation at Christmas, but she came anyway and refused to take off her coat. She only appeared in The Ugly Truth. She is stubborn. Reba was the sister of Grandpa, Loretta, and Arthur Heffley. She and Loretta are identical twins. In Wrecking Ball, it was revealed that she died in her sleep, and Greg's family attended someone else's funeral instead of hers by mistake, and receive an inheritance of her fortune. Greg forgot about Reba at first, until Frank and Susan reminded him that she used to send him angry letters for forgetting to send her thank-you notes for his birthday money.
Garrison "Gary" Heffley is Greg's uncle and the youngest brother of Frank and Joe, who has been married four times. He was first mentioned in The Last Straw when Greg said he was out of clean laundry and was going to have to wear a shirt he got from Gary's first wedding.
Gary makes his first major appearance in The Ugly Truth. It is revealed that all of his wives divorced him as soon as they found out about his financial situation and job. He has had so many weddings that Greg's family does not need to use a growth chart.
Gary returns in The Third Wheel and has a larger role. He comes to live with Greg's family after he discovers his job selling shirts in Boston was a ripoff. He was sold the shirts by a man claiming to have a good business for sale, and Gary bought the many boxes of shirts, unaware that the shirts said “Botson” instead of Boston. Later, he is chosen to be the DJ at Greg's Valentine's Day dance and he sells his shirts to Greg's classmates. He uses his money to buy scratch tickets and wins $40,000, allowing him to move out.
In Double Down, Gary accidentally breaks his collarbone while cutting down tree branches over his driveway.
In The Deep End, Gary is never seen, but it is revealed that he used to own a camper, which had been parked in Gammie's driveway for two years. She gives it to Greg's family after being fed up with it taking up space in her driveway.
Aunt Dorothy is Greg's great aunt and the wife of Charlie, who always kisses him on the lips. Greg's mother, Susan, says it is rude to wipe off the kisses Dorothy gives him, but Greg wipes his face on the nearest available curtain when no one is looking. She is overweight and sometimes passes gas loudly.
Arthur Heffley is Greg's great-uncle. He only speaks in grunts or makes random sounds. He never has an actual conversation with anybody, but sometimes Greg tries to respond to him just in case he is trying to communicate. Arthur is the brother of Reba, Grandpa, and Loretta Heffley.
Great Uncle Bruce
Great Uncle Bruce was Greg's deceased great-uncle. He is a character who is mentioned in Cabin Fever and The Third Wheel. Greg is presented with a rather luxurious blanket as a Christmas gift, only to be repelled by it upon learning that it had formerly belonged to Great Uncle Bruce before his death. In The Third Wheel, Greg uses Great Uncle Bruce's old cologne on Valentine's Day, which ends up attracting some old ladies.
Byron Heffley is Frank's cousin whom Greg is not excited to see because, at Gammie's last family meeting, they were sent out to get milk, but hit a pothole halfway home and got a flat tire. Byron told Greg to go to the house and get help. When Greg returned to Gammie's, the ladies needed to warn him of his muddy shoes because he was about to track mud into the house. Unfortunately, he forgot about Byron's tire, and he was not happy when he got to Gammie's a half-hour later.
He only appears in The Ugly Truth.
Benjy Heffley is Greg's cousin, whose parents are Greg's Uncle Tony and Aunt Patricia. The last time Greg saw Benjy, he could only say "No!" or "Shut up!", respectively. Now he can speak in full sentences and read chapter books but is still not potty trained and usually wears a diaper.
Terrence Heffley is Frank's second cousin and the eldest son of Charlie who is said to have looked like Greg when he was his age. Greg confirms this by looking in Gammie's photo album, and strives to save money for plastic surgery.
Lawrence Heffley is Greg's uncle who did not appear at uncle Gary's fourth wedding because he is always traveling. He is said to almost never come to family gatherings because of this, but he sometimes makes an appearance by webcam.
Aunt Audra is one of Susan's sisters. She believes in crystal balls and took Greg along with her to see her fortuneteller a few times. Susan thinks Audra is wasting her money. The fortuneteller also told Audra that Meemaw's ring was inside a photo album. It turned out the fortuneteller did not mean it literally.
Aunt Veronica is Greg's aunt and Susan's sister. Greg states that she has never been seen in person since he was three or four years old, probably because being with the family in person stresses her out, but calls her family members on video chat. When Greg was sitting on the toilet playing games on his new phone (which was actually a hand-me-down from his mother), she accidentally started a video chat with him. This startled him, leading to him dropping the phone into the toilet. She appears in Hard Luck multiple times by video conference on a tablet and the used phone that Susan gave to Greg.
Aunt Gretchen is Susan's youngest sister. She has two out-of-control twin sons, Malvin and Malcolm. Gretchen has at least thirty pets. In Hard Luck, she takes her pets with her, and her rabbit has a litter of bunnies, angering Frank since Gretchen lied that her rabbit was a boy.
Malvin and Malcolm
Malvin and Malcolm are Gretchen's two sons, the nephews of Susan, and the cousins of Greg, Rodrick, and Manny. They are out-of-control kids who used to wear child leashes. Once, they played throw and catch with a large sharp piece of concrete. Eventually, Malvin had to go to the emergency room to get stitches in his forehead. Malcolm is the wilder twin. While Malvin was getting stitches, Malcolm got hold of Frank's shaving kit and shaved his head and eyebrow. He also called the police to report Greg's family for running out of ketchup. This results in Frank angrily making them leave early.
Aunt Cakey is Susan's oldest sister. She is single and has no pets or kids, suggesting that she doesn't like kids. When she stayed with the Heffleys when Greg was little, she kept all fragile items out of his reach and made him take a nap. When she told Greg to not touch the iron, he can't stop thinking about it and pressed his whole hand against the iron, giving him a second-degree burn. Susan has never trusted her with babysitting since.
Gerald is Susan's cousin from California and the eldest son of Martina who lived with the Heffleys for a few months after Greg was born, which he reminds Greg of every time he sees him.
Martina is Susan's cousin who had gained a lot of money while in Las Vegas. She had been eating in a breakfast buffet in a hotel, when she mistook a full-length mirror for another room, causing Martina to run straight into the mirror, break her collarbone, and sue the hotel. Greg notes that a Porsche in Gramma's driveway was probably hers.
Uncle Larry is a man who is not actually related to anyone, but is a friend invited over one year and who has been showing up ever since. Greg likes him, but is annoyed that he always sits in Gramma's best chair until it is time to leave.
Gramma has two sisters whose names have not been confirmed yet but are suggested to be named Martha and Beatrice. They can not stand each other and try to give each other the most insulting gift they can think of.
Cecil is Greg's adopted uncle who is only three or four years old. He was adopted by Great Aunt Marcie, and Greg often feels awkward around Cecil.
Georgia is Greg's second cousin who has a very loose tooth that has been in her mouth for years and always stalls when people ask if they can pull it out.
Meemaw and Peepaw
Meemaw and Peepaw are the parents of Gramma and her two sisters, the maternal grandparents of Susan and the maternal great-grandparents of Rodrick, Greg and Manny. Their first appearance was in Hard Luck. Peepaw is portrayed as old and batty. Meemaw is dead, while Peepaw is still alive. Meemaw was in charge of putting prizes in the Easter eggs and wore a diamond ring, which was extremely valuable because it had been in her family for three generations. She used to overdo with hiding the Easter eggs, which results in Greg finding eggs in all sorts of strange places. As Meemaw got older, she became less sharp and started putting strange prizes in the eggs, such as a green bean, a bottle cap, and a paper clip. Before she died, she accidentally put her ring in an Easter egg that was found by Greg at the end of the book.
Meemaw appears in the film adaption of The Long Haul played by Mimi Gould. Meemaw's birthday results in Susan's "great Heffley road trip".
Robert Jefferson is Rowley's father. He is fairly paranoid and does not take kindly to criticism of himself or his property from anyone. He is a fairly strict father, not allowing Rowley play any video game with even a little violence or fighting in it, as he thinks doing this could have a negative effect on his son's character. However, he is also shown to be kind to his son, having a close bond with Rowley. Mr. Jefferson dislikes Greg, whom he thinks is a bad influence on his son. After Greg and Rowley invent their own secret language, which Mr. Jefferson cracks, he sends Greg home early.
In Dog Days, it is revealed that Mr. Jefferson's first name is Robert. When Susan emailed him because of the note Greg sent her, it had Mr. Jefferson's first name on it.
In "Old School", he is stuck chaperoning the group of extra kids (which includes Rowley and Greg), much to Greg's dismay. Later, Rowley adds poison ivy to a fire started by him and he has problems breathing the next morning, which means he and Rowley (who had spots on his body) would be going back home.
In the film series, Mr. Jefferson has not spoken until the third film, implying that he is a man of a few words.
Linda Jefferson is Rowley's mother. She often seems to be concerned about Rowley, such as the time he broke his big toe after Greg put one of his dad's dumbbells under a pillow that Rowley kept kicking at Greg's sleepover. She also had Greg apologize to her for what he did to Rowley. Despite this, Mrs. Jefferson always enjoys Greg's company with Rowley. Although Mrs. Jefferson likes Greg, she does not let him come over because her husband dislikes him. On day 24 of the online version, it is revealed that her first name is Linda from Greg's The Boy Whose Family Thinks He's a DOG comic.
In the film adaptations, Rowley's mother is portrayed by Kaye Capron in Diary of a Wimpy Kid (who in turn is the real-life mother of Robert Capron, the actor who plays Rowley) and by Bronwen Smith in Dog Days.
Rowley's grandfather only appears in Rodrick Rules in a minor role. The Jeffersons were holding a birthday party for him with Greg invited, where he states that he wants a chocolate cake the next year. Greg (who is bound by a promise to always tell the truth) then states his doubts of him being alive next year, angering Mr. Jefferson.
Fregley is Greg's acquaintance and neighbor noted for his many odd or disgusting eccentricities. He has been known to perplex others with his behavior and does not have any known friends. Greg has been forced to hang around with Fregley on several occasions, to his chagrin or aggravation. It has been mentioned that Fregley is prohibited from eating sugar by his parents, and the consumption of it in large quantities will send him into hysterical, uncontrollable frenzies. This occurs in the first book, when he eats Greg's jelly beans.
After Greg inadvertently causes the Snella family to move away due to a foul smell which (unknown to the Snellas) was caused by Greg dumping deviled eggs into a plastic plant, he decides that he should find a way of sneaking deviled eggs into Fregley's house.
In Hard Luck, Fregley is shown to have the talent of chewing gum and other foods with his bellybutton. Earning him the respect of many other kids, and allowing him to win the "Most Popular" class favorite category in the yearbook, where he shows he can also blow a bubble.
In the film adaptations of the books, Fregley is played by Grayson Russell.
Preston Mudd is one of Greg's classmates. He is said to have been the best player in the basketball unit of gym class during sixth grade at Westmore Middle School. Unfortunately, when his name was displayed as "P. Mudd" on the athlete of the month poster, this led to his classmates making fun of him, calling him "Pee Mud".
Christopher Brownfield is one of Greg's friends and is shown to have been a great mosquito magnet while hanging out with Greg in the summer. However, Greg does not see him as a close friend because he is "not a school-year friend". Later in "The Ugly Truth", he is on Greg's team for a game and hides behind a soda machine after the teachers threaten to call all of their parents.
Tyson Sanders is a friend of Greg who appears in "The Ugly Truth". He is mentioned at the beginning along with Christopher when Greg is considering new best friends, and mentions that although Tyson is nice and into the same video games as Greg, he is turned off by the fact Tyson pulls his pants all the way down when using the urinal. When they play a game of "Guess Who?", the team takes a picture of Tyson's bent arm, which gets them disqualified as the chaperones think the picture is of someone's buttocks. However, the misunderstanding is later cleared up after a mole near Tyson's elbow is matched to one shown in the picture. Greg remarks that everyone should know what Tyson's buttocks look like due to his habit of pulling his pants all the way down when using the urinal. He has made several cameo appearances in later books.
Holly Hills is one of Greg's classmates; a girl who primarily serves as Greg's unrequited romantic interest and also Heather Hills' younger sister. She is the youngest daughter of Mr. Hills and Mrs. Hills. A minor character, she earns a prominent role in The Last Straw as the object of Greg's most recent infatuation. He is continuously motivated to impress her to no avail. Virtually oblivious to Greg's existence or identity (Greg stops trying to impress her after she mistakes him for Fregley), she appears to take an interest in Rowley's sweetness, judging by an enthusiastic message which she had signed in his yearbook (as opposed to the note that she had written for the envious Greg). She seldom appears afterward. Greg's interest in her is seemingly damaged by events such as this and he starts showing an interest in other girls, including Holly's older sister Heather.
Holly makes a cameo in The Ugly Truth talking to some of her friends, and this is her most recent appearance in the books, though she was shown in a chart Greg drew in The Third Wheel as one of the many girls interested in Bryce Anderson.
Whereas her personality is hardly explored in the books, Holly's role was increased in film adaptions, debuting in Diary of a Wimpy Kid: Rodrick Rules as a newcomer to Greg's school with whom he is instantly besotted. She is depicted as being friendly and good-natured. She is given a girl-next-door attitude, which means that she is a sweet and caring girl with a heart of gold. The relationship she shares with Greg and Rowley is emphasized and exaggerated in the film portrayals, to the extent it can be assumed that the feelings Greg has for her may be mutual. She reappears in Diary of a Wimpy Kid: Dog Days.
Holly seems to enjoy the boys' companionship and shows gratitude for Rodrick Heffley's unintentional blunders that wind up destroying the undeserving Heather's birthday party. The party ends with Holly slipping her hand into Greg's, implying that she likes him as well, and she, Greg and Rowley had a pool party not long after.
Holly is portrayed in the movies by Peyton R. List.
Chirag Gupta is an Indian American who serves as one of Greg's schoolmates and a minor character in the books. He is characterized by his short stature. Although he and Greg are well-acquainted and generally amiable to one another, Greg started the "Invisible Chirag" prank in Rodrick Rules. During the summer the Gupta family were to move away but an unexplained alteration in their plans changed this. As a result, Chirag's classmates teasingly ignore his presence for days on end, which aggravates and shocks him. Greg is called into Mr. Roy's office and is severely reprimanded, but Mr. Roy gets the identity of the victim wrong. After Greg apologizes to a completely different student named Sharif, who does not understand why Greg is apologizing, Mr. Roy lets him go. However, after Susan gets a phone call from Chirag's father, she brings Greg to Chirag's house and orders him to apologise. Mr. Gupta is not impressed, but Chirag accepts the apology and forgives Greg.
Later in The Last Straw, Greg and some other students started talking very quietly around Chirag to trick him into thinking he was going Deaf. Chirag however told a teacher quickly because he didn't want the prank to escalate to the scale of the "Invisible Chirag" joke.
In The Ugly Truth, when Greg brags to his classmates about his family hiring a maid, Chirag says that his family does not need a maid and is glad that his mother is there when he comes home from school. Later in the book, he gets invited to Jordan Jury's party, only to discover that he and other kids in his grade are being used as servants.
Though Chirag has forgiven Greg and his fellow schoolmates for concocting the prank, Greg mentions in Cabin Fever that Chirag takes advantage of his family's non-observance of the Christmas holiday, and no obligation to behave for Santa Claus, to pick on Greg, and this is his most recent appearance.
In the movie adaptions, Chirag's role is enhanced and he is a close friend of Greg and Rowley. He also plays a considerably more prominent role in these films, appearing in adaptions of books in which he is absent or hardly mentioned. He is portrayed by American actor Karan Brar, who is of Indian ancestry.
Patty Farrell is a minor character who shares an intense rivalry with Greg, which is showcased on a few occasions. It is implied she is a hardworking but sanctimonious and domineering student. She earns Greg's animosity after she suggests a map of the United States displayed in the classroom be covered during a geography quiz. Greg had planned to cheat using the map and this causes great difficulties for him, and makes him agitated. Motivated by his lust for revenge, he volunteers to play a tree in the school's upcoming production of "The Wizard of Oz"after viewing the movie adaption for the first time. He believes the role entails having to bombard the character of Dorothy Gale (whom Patty would be portraying in the play) with apples, only to learn that this scene was deleted for the school production. He winds up re-enacting this scene, despite the script, and the other trees join in. However, the play has to be shut down after Patty's glasses are broken, as Patty is short-sighted. She has yet to play quite as significant a role in the book series again. She has become something of a minor recurring character whose appearances are rare.
In the film adaptions of the books, Patty's role is enhanced slightly. She is depicted as being monstrously demanding. Her parents are involved with the school board in this portrayal. The motivation given for her hatred of Greg is his recital of an offensive playground chant poking fun at her that sent her bursting into tears in elementary school. She appears in the film adaptations of all three films Diary of a Wimpy Kid, Diary of a Wimpy Kid; Rodrick Rules and Diary of a Wimpy Kid: Dog Days. Alterations made to the books include her talent for both wrestling and playing tennis. She snatches any opportunity to assault Greg somehow while engaged in either sport with him.
She is portrayed in the movies by Laine MacNeil.
Heather Hills is the attractive elder sister of Holly Hills, with whom Rodrick is infatuated. A minor character in the books, but the main antagonist in the third film, Heather is only featured in several books as the object of Greg's unrequited infatuation. However, she seems oblivious to this. A student attending Westmore High School with Rodrick, she has had several minor occupations throughout the books, during each of which Rodrick fecklessly attempts to grab her attention or to impress her. Little insight into her personality is provided in the book series.
Heather only appears in the third movie in the film series, Dog Days wherein personality and role is further enhanced similar to her younger sister, Holly. In a modification of the events of the books, she is depicted as the spoiled, obnoxious, grouchy, ignorant, sarcastic, conceited, irritable, unforgiving, cold-hearted, and demanding oldest daughter of the Hills family who often mistreats her family and acquaintances. A lovelorn Rodrick Heffley and his band are hired to perform at Heather's ostentatious upcoming sixteenth birthday party on the suggestion by Greg himself. In an attempt to earn her admiration, Rodrick sings lead on the band's cover of Justin Bieber and Ludacris's hit song "Baby" (while his bandmate plays drums), which he claims is her favorite song, but chaos ensues when the band switches from the song's original, dance-infused pop tempo to an extremely wild, boisterous, punk rock version of the song wherein Rodrick inadvertently messes with the decorations. This angers Heather and the party ends in disaster.
She is portrayed in Dog Days by Melissa Roxburgh.
Albert Sandy is a minor character, who talks often about rumors he has heard. The validity of his statements is unconfirmed. One of the statements which were not confirmed by Greg was when Albert told him that "it was medically impossible for a girl to fart". Some make no sense, for example, he said a man got decapitated when he sneezed.
Albert has appeared in The Last Straw, The Ugly Truth, Old School, Double Down, The Meltdown, Wrecking Ball, and The Deep End.
Bryce Anderson is the most popular kid in Greg's grade. He is adored by the girls in the school, despite only becoming interested in them in the last couple of years (he used to call them "stinky poos" in elementary school). Bryce has a group of "cronies" who are always loyal to him and often help out on his projects. One summer, they set up a restaurant for the parents in the neighborhood, and earned $300 with one crony buying a BB gun with his share. When Greg was a photographer for the yearbook, Bryce was said to have won "Best Hair".
Bryce has appeared or been mentioned in Diary of a Wimpy Kid, The Last Straw, The Ugly Truth, Cabin Fever, The Third Wheel, and Hard Luck.
Abigail Brown is a minor character and the daughter of a state trooper. She goes to the school's Valentine's Day Dance with Greg and Rowley, and cries after finding out that her boyfriend, Michael Sampson, was cheating on her (having attended the dance with another girl). She is upset further after Greg freaks out after thinking she has the chicken pox. At some point afterwards, Abigail and Rowley start dating, and she causes him to start dressing and behaving differently much to the annoyance of Greg. They are voted Cutest Couple which causes Greg to resign as the yearbook photographer. Not long afterwards, Abigail breaks up with Rowley and gets back with Michael, causing Greg to feel sorry for Rowley and they become best friends again. It is heavily implied that Abigail only went out with Rowley to make Michael jealous.
Abigail appears in The Third Wheel and Hard Luck.
The Mingos are a group of wild kids who live in the woods and don't attend school, not much is known about them. Their main camp consists of several abandoned cars and trucks deep in the woods, which had remained unknown to the town until Greg and Rowley accidentally discovered it. it is heavily implied that the Mingos hibernate over the winter, as they are not seen until the spring and look like they just woke up. There are no known grown-ups or parents in the clan, though the leader (who appears to be the oldest) is named Meckley Mingo, who has a giant metal belt buckle.
The Mingos are very territorial and often make threats to people who walk past their woods, even to the point of chasing and attacking them with Meckley using his belt as a whip. They are suggested to speak in a southern drawl, as one kid used the word "git" (get). They have been shown to wake up early during the winter when they are disturbed and will go to great lengths to get back at an insult (Greg infiltrating the camp and accidentally stealing Meckley's belt buckle).
The Mingo clan has appeared in Hard Luck, and The Meltdown.
Dennis Denard and Erick Glick
Dennis Denard and Erick Glick are two eighth graders who run an illegal homework assignment and school project business that has them selling old projects from the school's storage room. Dennis is the ringleader while Erick acts as his public face. Dennis was also said to have been held back twice (probably on purpose so he could continue his business). In "Hard Luck", Greg attempts to buy an old science project from them, but eventually has second thoughts, thinking it would be his first step toward the life of a criminal. At the end of the book, another kid tips off a teacher, causing the faculty members to stage a raid on the storage room. Dennis, Erick, and everyone else who was caught were given detention for the rest of their time in school, and Greg believes that it also includes an automatic trip to summer school.
The Snellas are a family that lives in the Heffleys' neighborhood. They have a lot of children, all of whom are male, with names beginning with the letter S. Five of the children's names are revealed, and they are (from oldest to youngest): Shawn, Shane, Sam, Scott, and Seth. Their first appearance is in Diary of a Wimpy Kid, in which Shane Snella pays to go through Greg and Rowley's haunted house, getting too scared to continue in the process. Both Shawn Snella and his father appear in Rodrick Rules, in which Shawn tells Greg his plan to become a Basketball player. Greg (who is bound by a promise to never lie) states his doubts by pointing out the short stature of both the parental Snellas and Shawn's current weight, hurting Shawn's feelings.
In The Last Straw, it is revealed that each Snella child has a half birthday party at which the adults perform funny stunts, to attempt to make the babies laugh. According to Greg, however, no baby has laughed once. Mr. Snella then sends the videos to America's Funniest Families, a spoof and parody of America's Funniest Home Videos, and has never won anything (though after Greg is filmed wearing Wonder Woman underwear hanging off a tree with his trousers below his ankles at the end of The Last Straw, the footage is sent, and it is never explained if Mr. Snella won with it).
Their most recent appearance was in The Ugly Truth when they move to another house because of a strange smell they cannot get rid of in their home following another half birthday party for an unnamed child. The smell was deviled eggs, which Greg hates and threw into one of their plant pots when he was having dinner at their house. Despite trying to find the cause of the smell, the Snellas cannot figure it out and eventually just move. Greg feels guilty when he sees that they are taking the plant pot with them, but he resolves to try to find a way to sneak deviled eggs into Fregley's house.
In Cabin Fever, their vacant house is moved into by a man called Mr. Alexander, who has uneven teeth that Greg's dad thought were fake the first time they met.
Scotty is a first grader from Rowley's karate class. In Rodrick Rules, Scotty was going to do a magic act in the Talent Show with Rowley as his assistant. But after Greg breaks Rowley's big toe, he has to fill in for Rowley. Greg complains about being a magician's assistant to Scotty, but Susan tells Scotty's mother that Greg would be happy to replace Rowley.
Scotty has a remarkably similar appearance to Greg's comic character, Creighton The Cretin, except Creighton's eyes are wide open and Scotty's eyes are beady just like all the other characters that do not wear glasses. In The Ugly Truth, he becomes the new Peachy Breeze kid, yet cannot say the slogan right. Between Rodrick Rules and The Ugly Truth it appears that Scotty has two siblings - an unnamed baby sister and an older brother. In The Third Wheel, when Greg and Rowley become private investigators Greg looks through the window at his house to find him playing one of Greg's video games with Rowley.
He appeared in the film adaptation of Rodrick Rules, with only a few lines. He is portrayed by Jakob Davies.
Mr. Underwood is Greg's P.E. coach. Once he was bitten in the arm by Ruby Bird, and one of her teeth got stuck in his arm.
In the film series, he is named Coach Malone. He is portrayed by Andrew McNee.
Bill Walter is a 35-year-old unemployed high school drop out, guitarist and professional singer, who has a rude attitude towards everyone he meets. Rodrick idolizes him and his lifestyle. In the novel Rodrick Rules, he was voted "Most Likely to Be a Rock Star" which influenced Rodrick to persuade him to join the band. Frank Heffley strongly dislikes Bill because he disapproves of his lifestyle, and is afraid Rodrick will follow in his footsteps. In the movie version of Rodrick Rules, he is portrayed by Fran Kranz and is an antagonist. He agrees to join Rodrick's rock band Loded Diper and later attempts to kick him out for an unknown reason. After performing the song Exploded Diper, Rodrick retaliates and kicks him out. In the book Greg describes him as unemployed and still living with his parents. Also, in Rodrick Rules Bill appears to be a slob, as he "slorks" pot roast.
Dr. Salazar Kagan
Dr. Kagan, Frank's dentist, makes his debut in The Ugly Truth. Frank takes Greg to Dr. Kagan instead of his usual dentist, a pretty woman named Rachel on whom Greg has a crush. Dr. Kagan has a very different approach to dentistry than Rachel. When Greg admits to drinking soda, Dr. Kagan is infuriated, and shows Greg a jar of liquid with a badly eroded tooth in it, telling him that it is a real tooth that was left in a jar of soda for 24 hours. Greg accidentally bites Dr. Kagan's finger when his teeth are being checked. In what Greg believes to be an act of revenge, Dr. Kagan tells Frank that Greg needs headgear to correct his overbite. Greg later loses his headgear, and discovers that Manny took it. He declares that he will never wear the headgear again irrespective of what Dr. Kagan says.
Greg says Dr. Kagan is "scary" and "evil" and that he never fools around. He has sharp metal tools, which he leaves on full display, and never smiles. The billboards for Dr. Kagan's dental practice make Greg freak out every time he sees one of them on the highway.
Dr. Kagan later makes a cameo in Double Down, in a scene where Greg describes how a Spineticklers book has made going to the dentist an even more frightening experience for him.
Greg's cantankerous History teacher who only appears in Rodrick Rules, where it is revealed that he previously had Rodrick as a student when he was in middle school, prompting him to have Greg sit in a chair next to his desk. When Greg is assigned to write a poem about events from a hundred years ago (the early 1900s), Greg attempted to blow the project off until the day it was due, counting on snow to cancel school, but discovered that the snowstorm had blown past them. After asking his Dad for help, and attempting to write it himself (the power went out), Greg buys Rodrick's version of the assignment, as he got it in middle school too. But on the bus, Greg discovers the poem was written in Rodrick's handwriting and has numerous inconsistencies with the time period, and history as a whole. In History, Greg didn't have anything to turn in, prompting him to believe he would need to go to summer school, though he doesn't have to in The Last Straw.
In the movie version of Rodrick Rules, Mr. Huff's name is changed to Mr. Draybick and he is portrayed by John Shaw. In the movie, he only moves Greg next to him when Greg attempts to pass a note to Holly Hills. Also, Greg turns in his (Rodrick's) assignment without looking at it first. Mr. Draybick recognizes the assignment and he has Greg read it out loud to the class, much to Greg's embarrassment. He also appears briefly in the movie version of Dog Days on the last day of school, in which everyone but Greg brought their History textbook, forcing Greg to partner with Fregley so they could share textbooks.
Lenwood Heath only appears in The Last Straw. He is a rebellious teenager, who was Frank's arch-enemy for about three months before he was sent to military academy. This resulted in him becoming a fine young man who works at the movie theater. Frank now admires Lenwood, despite the history between the two of them. To Greg's horror, Frank decides to sign Greg up for the same military academy that Lenwood attended, leading to Greg taking measures to convince him to change his mind. In the Dog Days film, he is portrayed by Tom Stevens and is seen working as a lifeguard at the community pool the Heffleys go to.
Taylor Pringle is a minor character who only appears in the films, Diary of a Wimpy Kid: Rodrick Rules and Diary of a Wimpy Kid: Dog Days and does not appear in the books. She is a very rude little girl and is first seen at the end of the opening scene in Rodrick Rules in which during her birthday party at the roller rink, Rodrick embarrasses Greg, prompting Greg to try and tackle him, but he misses and face-plants in Taylor's birthday cake, destroying it. As a result of this, Taylor gets angry and she and her friends begin beating up Greg as the intro begins. Later in the film, during church, when Rodrick intentionally pulls down the sweater around Greg's waist to reveal the chocolate stain on Greg's pants, Taylor points it out to everyone, mistaking it for poop. Then, in Dog Days, when Greg attempts to impress Holly by jumping off the high diving board, he becomes nervous, due to it being very high above the water. Taylor then comes up behind Greg and states that he is talking to himself, due to being scared. When Greg gives Taylor a brush-off that he is not scared and that she would not understand since she is "just a little kid", she pressures him to jump. When Greg jumps, he loses his swimsuit on the board, and Taylor chucks it onto a nearby fence to get back at Greg for brushing her off. As a result, Greg is forced to borrow a girl's swimsuit that reads Princess on it until he goes to the fence to retrieve his own swimsuit, and as he does so, he gets taunted by Patty. Taylor is portrayed by Dalila Bela.
Only appearing in The Ugly Truth, Jordan Jury is the popular boy in the grade above Greg, who is known for always throwing huge parties that have little to no adult supervision. Greg is amazed when he discovers that he has been given a textbook that used to belong to him. Jordan invites Greg and Rowley to his latest party, but Greg cannot not go because of his Uncle Gary's fourth wedding. But at the end of the book, Greg discovers that he is lucky that he didn't go, because the only reason Jordan invited the kids in Greg and Rowley's grade was to use them as servants.
Angie Steadman only appears as an additional character in the Diary of a Wimpy Kid film. She is in seventh grade, has a pink streak of hair, works for the school newspaper, and hates middle school. In the film, Greg and Rowley meet her under the bleachers during a game of "Gladiator". She gets along with Rowley, but starts a rocky relationship with Greg after he egotistically declines her offer to join the school newspaper.

In the film, she is portrayed by Chloë Grace Moretz.
Pete Hosey is the leader of the teenagers who attacked Greg and Rowley on Halloween. He is an antagonist in the first film. He is unnamed in the first book and he is replaced by Herbie Reamer in the online version. After hassling Greg and Rowley on Halloween, Greg yells that he will call the cops, and they chase him to Greg's grandmother's house. In the book, Greg and Rowley sneak back home, but in the movie, they try to intimidate Pete and his friends with a weed hacker, before Pete scratches his car and they are chased into the woods. In both the book and the movie, the teens hold a vendetta against Greg and Rowley. Near the end they corner them on the school field and decide to force them to eat the moldy cheese. Rowley is forced to eat the cheese, but Greg avoids it by saying he's lactose intolerant. In the movie they are chased off by the coach.
Although his family is vaguely referenced in the books, the Warren's are what got Frank thinking of making Greg more manly. In the books, Mr. Warren is Frank's boss. Frank is deeply jealous of the Warrens. In stark contrast to Greg, the Warrens' children are shown to be athletic and sporty. In the third film, Stan, the father of the family, is shown to be a neighbor of the Heffleys. He had a minor childhood rivalry with Frank, that they appear to have gotten over as adults. In the movie, Mr. Warren is the troop master of the Wilderness Explorers, and invites everyone over for an Independence Day party. They only appear in Diary of a Wimpy Kid: The Last Straw.
Only appearing in The Long Haul, the Beardos are the main antagonists of the book. They are a couple with three sons who drive the same model van as the Heffleys in a different color. The Heffleys indirectly met them during their road trip, though only Greg knows who they are. Their first encounter is at a motel, where Greg angrily berates the Beardo children for making noise, the youngest then tells his father on him, causing Greg to fear running into them again. Greg sees them again on the road, the country fair, and a waterpark called "Soak Central".
Greg and his family are convinced that the Beardos have stolen their luggage and belongings at Soak Central after they steal their pool chair and they find their supposed locker empty. The Heffleys try to track them down but couldn't since they didn't know their number plate. On the trip back home, Greg recognizes the Beardo's van outside a motel, prompting the Heffley's to sneak into their room to look for their stolen belongings. When the Beardos return too early, they catch Frank Heffley using the toilet, who escapes and throws the Beardo's keys away so they couldn't be chased. At the end, Greg discovers that he actually had the key to the locker in Soak Central, and that he got the number in the lottery. The family's real surname is unknown, as Greg himself does not know who they are. It is likely he dubbed them this because of the patriarch's noticeably long beard.
In the film adaption of The Long Haul, Mr. and Mrs. Beardo are portrayed by Chris Coppola and Kimberli Lincoln and have a daughter named Brandi and two sons named Brandon and Brent. They also drive a different van from the Heffley's, contrasting from the book. The Beardos are depicted as much more malicious, with Mr. Beardo chasing Greg around through the carnival in order to get revenge on him. The Beardos also really do steal some of the Heffley's luggage, which they later recover.
Chris is a friend of Rodrick and the bassist of Löded Diper.
Joshie is a singer who is famous in Europe and is Rowley's favorite singer and idol. Greg believes that Joshie is for six-year-old girls, but Rowley ignores him, saying that Greg is jealous because he was the one who "discovered" Joshie. However, despite Rowley's opinion, Joshie appears to be a singer that is mainly idolized by females.
Maddox Selsam is a boy who lives in the middle of the woods. He is not allowed to have any screen time, and does not have a TV at his house. He enjoys playing with his Legos and practicing his violin. He met Greg in Double Down when he found Greg's balloon for the Balloon Brigade at his school. Susan only likes him because he doesn't have electronics in his house and wants Maddox to be a role model for Greg; however, Maddox was rude to Greg. She feels disappointed that he and Greg didn't "hit it off", although she knew she had made a mistake about Maddox.
Sweetie is a dog that first appeared in Dog Days. Greg's dad buys him after discovering that his own father lied about accidentally killing his childhood dog, Nutty. Sweetie wreaks havoc in the Heffley household and is given to Gramma at the end of the book. In Cabin Fever, Sweetie undergoes drastic weight gain at Gramma's house because he is fed many table scraps. Sweetie is mentioned in The Third Wheel when Greg explains that Manny locks himself in Sweetie's old playpen to avoid interacting with other kids. In Hard Luck, Gramma dresses Sweetie up like a little human. Greg and Rodrick like playing with him by going up behind him and making flatulence sounds. He will then sniff his rear end until he goes to sleep. In The Long Haul, Greg mentions in a flashback where Susan took Sweetie to the vet to get his stomach pumped, because she saw some whoopie pie wrappers on the floor, causing her to think Sweetie ate the whoopie pies, but Greg actually ate them. In The Meltdown, Greg imagines Sweetie sunbathing when Gramma takes him to the beach. In The Deep End, Greg tries to sleep in Gramma's guest room, but Sweetie refuses to share the room.
Greg and Rodrick's fish
In "Dog Days", Greg's mom gives her sons five dollars to buy something they wanted. Greg buys an angelfish that was many different colors, and Rodrick buys a piranha-like fish that was said to be "aggressive". While Greg bought a journal to track everything his fish did, Rodrick neglected his fish to the point of putting its filthy bowl on top of the refrigerator and never feeding it or cleaning it once. When Greg and his family go to a waterpark, Greg's mom puts Rodrick's fish in the same bowl as Greg's fish as it was cleaner. By the time the Heffleys got home, Rodrick's fish had eaten Greg's, and was never referred to in the books after that. The fishes were named Luke and Mason.
The Heffleys’ pet pig, in the film named "Piggy", was introduced in The Long Haul, in which Manny Heffley won it at a country fair for correctly guessing the weight of a hog. In Old School and Double Down, to the annoyance of Greg, the Pig exhibits extraordinary intelligence and gains human characteristics. One running gag is that despite not having opposable thumbs, the Pig opens objects such as soda cans. In The Meltdown, the Pig throws a tantrum for being excluded from the trip to Isla de Corales in The Getaway. Frank sends it to obedience school, only for the Pig to escape on its second day there. The Pig is never found by the Heffleys despite numerous missing posters, and since The Meltdown, the Pig is never seen or mentioned again. Although in the Wrecking Ball, the pig may make an appearance when Manny threw his stuffed animals out the window and jumped because of a fire alarm. The pig can be seen in the pile of toys although this is not confirmed.
