List of Diary of a Wimpy Kid characters

Greg Heffley

Gregory "Greg" Heffley is the main protagonist of the Diary of a Wimpy Kid series. Greg is 13 years old. Greg's actions can however 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 even praying for bad stuff to happen to others. However, he can also be a kind hearted character. He helps his brother with his homework at the climax of Rodrick Rules, gets his friend a date for a dance in The Third Wheel, helps out, and forgives his friends.

Rowley Jefferson

Rowlerius "Rowley" Jefferson is Greg's best friend, and the secondary protagonist.

In the first book, Rowley is the main antagonist. In Dog Days, they separate after Rowley damages Greg's chances of winning a video game championship, but they get back together at the end of The Ugly Truth. At the end of 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 is the main antagonist, ditching Greg for his new girlfriend Abigail. At the end of the book, the couple break up and he becomes friends with Greg again.

Rowley has what Greg considers strange interests for his age and gender, such as liking a singer for "eight-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 claims that Greg had nothing to do with the comic strip in the first book, a rare antagonistic move from him. In the movie series, Rowley is portrayed by Robert Capron. Rowley's shortest appearance was in The Long Haul, where he is only mentioned on one page.

Susan Heffley

Susan Heffley is Greg's mother. Though she is loving and motherly, she sometimes seems naive, embarrassing, and overprotective, apparently thinking she knows about what kids Greg's age are into when in fact, this is not the case. She and her husband pay far more attention to Manny than their other two sons. She is portrayed by Rachael Harris in the film series. In the online version of the first book, Susan was known as Ann Heffley.

Frank Heffley

Franklin "Frank" Heffley is Greg's overreactive but well-meaning father. He is interested in U.S. history, and his replica of a Civil War battlefield is a plot point in the series. Frank is edgy around Rowley, does not appreciate Greg's skill at video games,and loathes heavy metal, and adolescents. In Rodrick Rules, during Thanksgiving dinner, Frank turns up the thermostat to make everyone leave. 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. Frank is portrayed by Steve Zahn in the first three films of the Diary of a Wimpy Kid film series. In Diary of a Wimpy Kid: The Long Haul, he is played by Tom Everett Scott.

Manny Heffley

Manuel "Manny" Heffley is Greg and Rodrick's younger brother. He is an annoying, spoiled child who is constantly doted on by his mother. He makes a great number of demands and throws temper tantrums if they are not fulfilled. Among Manny's most well-known characteristics are his refusal to be toilet-trained and his complete inability to remain in nursery school. He frequently damages Greg's property. Whenever they go on vacations, Manny ends up ruining it and gets away with it. The excessive coddling he receives from his parents infuriates Greg. He also takes advantage of his overindulgence. It is revealed in The Third Wheel that Manny has imaginary friends, whom he blames for his misbehavior .Despite his very young age and spoilt attitude, Manny shows signs of actually possessing more intelligence than he appears to have. He surprises his family by his ability to speak Spanish in The Long Haul, but plays this to his advantage by persuading some Spanish men to take them to retrieve their pet pig. He is his grandmother's favorite, although she denies this.

Manny has similar traits to those of Farley Drexel "Fudge" Hatcher.

Rodrick Heffley

Rodrick is Greg's aggressive older brother. He is the drummer in a garage band called "Löded Diper" (loaded diaper), noted for their substandard heavy metal concerts and limited musical abilities. Rodrick is not an exception to Mr. Heffley's notorious distrust of all teenagers. Rodrick is notorious for his stereotypical rebellious nature, feigning illness in Rodrick Rules so as to be allowed to remain at home to throw a chaotic house party during his parents' absence, only for the evidence to appear in newly developed photographs that are quickly discovered by the boys' parents. He bullies Greg a lot and pulls awful pranks that ruins Greg's and his family's life. Rodrick also possesses incompetent tendencies, as his school assignments are notoriously crude and idiotic. He assumes that Abraham Lincoln was the author of To Kill a Mockingbird and, with Greg's aid, bases a science presentation around the hypothesis of whether or not plants sneeze. His spelling abilities are also poor, and he devotes a lot of time to tormenting Greg. In Rodrick Rules, Greg is haunted by the fact that Rodrick knows about his most mortifying experience during the summertime. This haunts him when he returns to school. However, his fears are quickly eased after the story becomes distorted to Greg's advantage due to it being passed around by so many people (à la Chinese Whispers), temporarily boosting his popularity. In the film series based on the books, Rodrick is played by Devon Bostick.

Grandma and Grampa

Grandma and Grampa are Susan's parents and Greg's maternal grandparents. Grandma 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 dad will not do this when she is around. When she is about to leave, Greg quickly goes to accompany her. Grampa has not appeared in the book series thus far (except for the Do it Yourself book, in a family tree), implying that he and Grandma were divorced or he died.

Grandpa Heffley

Greg's paternal grandpa is a typical unpredictable grandfather who is asked to babysit Rodrick and his brother in Rodrick Rules. He lives in a care home called Leisure Towers and enjoys playing games such as "Gutbusters", which the two boys find boring. Grandpa is a smoker. He has his television tuned to the CCTV in the care 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 book "Hard Luck" and broke up with her in the book "Old School". Grandpa dates on online. Greg is his favorite. Grandpa is known for making an awful dish named "Watercress Salad" which is just cucumber and floating beans in a pool of vinegar this dish is hated by Greg but Rodrick makes him have more. It's stated that Grandpa never spent much time with Frank when Frank was a boy.

Joe Heffley

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 insisted that there was a "potty monster" that was about to get him, causing him to fear using the bathroom, forcing Frank to change his diapers for a longer time. Greg says that he could hear Frank cursing at Joe when he changed Manny's diapers because of this. Uncle Joe's children call their uncle "Aunt Fwank", which Frank swears he told them to do on purpose; Susan thinks it's cute. In Dog Days, Greg mentions that he tried to make Uncle 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.

Charlie Heffley

Charlie Heffley is Nana Heffley'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 his parents have forbidden him from receiving. However, this backfires as he is usually given the wrong thing. For example, Greg wanted to use a Barbie dollhouse as a fort for his soldier action figures, but Charlie gave him a Barbie doll instead. Also, when it was brought up at a family meeting that Greg was into superheroes, he received Wonder Woman underwear. Charlie is a bachelor and spends his spare money well. Greg says he wants to follow in his footsteps. in the first book, Greg thought Charlie got him Twisted Wizard because of the size of the box, but it was just an 8x10 picture of Charlie. 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.

Uncle Cecil

Cecil is the boys' uncle but is only 3 or 4 years old. He sits at the grown-ups table at family gatherings because Greg's Great Aunt Marcie adopted him and since he's her son, he's allowed to sit at the grown-ups' table. He only appears in Hard Luck.

Loretta Heffley

Loretta Heffley is Greg's great-aunt and the sister of Grandpa, Arthur and Reba. Not much is known about her. 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.

Aunt Veronica

Aunt Veronica is Greg's aunt and Susan's sister. Greg states that she has never been seen in person since he was 2 or 3 years old, but calls his family members on video chat. When Greg was sitting on the toilet playing games on his brand new phone (which was actually a hand-me-down from his mother), she 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 - often in person - but on other occasions by video conference on a tablet and the used phone that Susan gave to Greg.

Terrence Heffley

Terrence, who has a mustache and glasses, is Frank's second cousin. It is implied that Greg thinks he is ugly. This was suggested when he was explaining that when Terrence was his age, he looked exactly like him, which is true. Greg then mentions he better start saving up for plastic surgery.

Gammie Heffley

Gammie is Greg's great-grandmother, and the unofficial head of the Heffley family. She only appears in The Ugly Truth, as a minor character. She also has Legos that Susan bought so that her kids had something to do at her house. Gammie glued them together to make one whole brick because of the mess the blocks make. 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 very big rush to visit her. When they all arrived Frank told Gammie that to win you had to match up three pictures. When she found this out, she did not really care. She pulled a roast right out of the oven, and Greg figures she got what she really 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.

Reba Heffley

Reba Heffley is Greg's great-aunt. Gammie forgot to give her an invitation at Christmas, but she came anyway. She made everyone feel guilty. She only appears in The Ugly Truth. She and Loretta are identical twins. Reba is the sister of Grandpa, Loretta, and Arthur Heffley.

Gary Heffley

Gary is Greg's uncle and has been married four times. 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. In The Third Wheel he comes to live with Greg's family after he discovers his job selling shirts in Boston was a ripoff - "Boston" was spelled "Botson". Later in the book he is chosen to be the DJ at Greg's Valentine's Day dance.

In Double Down, Gary cut down a big branch hanging over his driveway and ended up breaking his collarbone.

First wife: Linda

Reason for divorce: Job unappealing for her (worked at party place)

Second wife: Charlene

Reason for divorce: Financial miscommunication (He had $45 in his bank instead of $45,000.)

Third wife: Lydia

Reason for divorce: Unknown, possibly because of a tattoo that used to read "Lydia" (and was later modified to read "I am not in love with Lydia anymore").

Fourth wife: Sonja

Reason for likely divorce: He was only engaged to her by accident when a plane with a banner saying "MARRY ME SONJA" flew over the baseball game where he was going to break up with her because he wanted to start dating her sister. Apparently, there was another Sonja at the baseball stadium. Before Gary could say anything, Sonja turned around and said "YES, YES!" When they divorced, it was after their wedding when Gary's friend included the story in his speech.

Aunt Dorothy

She is Greg's aunt who always kisses him on the lips. Greg's mom, Susan, says it is rude to wipe off the kisses Dorothy gives him. She is overweight and obese and sometimes passes way too much gas, much to Greg's dismay.

She appears on the "Have You Ever" page in the Do-It-Yourself Book when Greg asks: "Have you ever been kissed full on the lips by a relative who's older than seventy?" This suggests she might be older than 70 years old.

Arthur Heffley

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. For example, once when he said "Rrup?", Greg replied "Umm...No thank you". He wears glasses and a neck tie. Arthur is the brother of Reba, Grandpa, and Loretta Heffley.

Great Uncle Bruce

Great Uncle Bruce is a deceased 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. This leads him to give it to an unsuspecting Rodrick as a birthday present. 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

Byron is Frank's cousin whom Greg is not excited to see because at Gammie's last meeting, he was sent out to get milk, but hit a pothole halfway home, and got a flat tire. Greg had to get him. He needed supplies, so Greg returned to Gammie's. Because of his muddy shoes the ladies needed to warn him since 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. Byron is Arthur Heffley's son.

He only appears in The Ugly Truth.

Nana Heffley

Not much is known about Nana, but according to a young Greg, she smelt like asparagus. She is Greg, Rodrick, and Manny's paternal grandmother, mother to Frank, Joe and Gary, and Mother-in-law to Susan. She is Grandpa's wife. It is revealed in Double Down she died when Greg was younger and it makes him uncomfortable to think she is "watching" him from heaven.

Her first appearance was in Double Down.

Aunt Cakey

Aunt Cakey is Susan's oldest sister and does not like kids. She used to have a dog named Rudy. Greg 's mom now never trusts to babysit Greg

Aunt Gretchen

Aunt Gretchen is Susan's youngest sister. She has two out-of-control twin sons, Malvin and Malcolm. Aunt Gretchen has at least thirty pets. In Hard Luck, her rabbit (which everyone thought was a male) has a litter of bunnies, angering Frank. Once they played throw and catch with a strong sharp piece of concrete. Malvin had to go to the emergency room to get stitches.

Malvin and Malcolm

Malvin and Malcolm are Gretchen's two sons. They are out-of control kids, playing catch with rocks and cement chunks. Malcolm is the wilder. He once got hold of Frank's shaving kit and shaved himself. He also called the police to report Greg's family for running out of ketchup. This results in Frank angrily making them leave.

Meemaw and Peepaw

Meemaw and Peepaw are the parents of Gramma and her two sisters, and are the grandparents of Susan. 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. Before she died, she accidentally put her ring in an Easter egg that was found by Greg at the end of the book.

Gramma's sisters

Gramma's sisters are the great-aunts of Rodrick, Greg, and Manny. They are the aunts of Susan Heffley and her sisters.

Mr. Jefferson

Mr. Jefferson is Rowley's father, and is far more shrill than Mr. Heffley. He is extremely rude and paranoid, and does not accept any criticism from anyone of himself or his property. He is the strictest father in the series so far. He will not let Rowley play any video game with the slightest bit of violence or fighting in it, as he thinks doing this could change Rowley into a different person. Mr. Jefferson thinks Greg is a "bad influence" on his son. It is also shown that Mr. Jefferson had a close bond with Rowley.

He shows little interest in sports until Dog Days, where he is found playing tennis with Rowley and golf with a caddy. In Rodrick Rules, Greg and Rowley say in their secret language: "Your-pa dad-pa smells-pa like-pa a woman-pa!" Greg is then forced to go home, and questions how Mr. Jefferson cracked the code.

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 on 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.

Mrs. Jefferson

Mrs. 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 loves Greg, she does not let him come over because her husband dislikes him. In 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 first film, Rowley's mother is portrayed by Kaye Capron, Robert Capron's real life mother; in Dog Days she is portrayed by Bronwen Smith.

Rowley's grandfather

Rowley's grandfather only appears in Rodrick Rules. It is his birthday and he asks for a chocolate cake for his next birthday. Because of his no lying policy Greg replies: "If you're even alive next year". He is 90 years old

In the Rodrick Rules movie, Greg's grandfather has this role instead.

Fregley

Fregley is Greg's firm and impeccably graspable acquaintance and neighbor noted for his unexplained lot of 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. Fregley won the "Student of the Week" award in "Cabin Fever" for not biting anyone for five days. In the film adaptions of the books, Fregley is played by Grayson Russell. In the films, he is a close friend of Greg, while in the book series, Greg always tries to avoid him.

Holly Elizabeth Hills

Holly Elizabeth Hills is the name of one of Greg's classmates; an older girl who primarily serves as Greg's unrequited romantic interest. 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.

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 middle school with whom he is instantly besotted. She is depicted as being friendly and good-natured. 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. Her family is portrayed as being wealthy and her sister shown to be tyrannical, spoiled, and selfish. Her sister has a slight reference to the Carnotaur from Disney's Dinosaur.

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 movie ends with Holly slipping her hand into Greg's. Holly is portrayed by Peyton R. List.

Chirag Gupta

Chirag Gupta is 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 existence or presence for days on end, which aggravates and shocks him. Though Chirag has apparently forgiven Greg and his fellow schoolmates for concocting the prank, it is mentioned in one book that he takes advantage of his family's non-observance of the Christmas holiday, and no obligation to behave for Santa Claus, to pick on Greg.

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 depicted as being Indian-American. He is portrayed by Karan Brar.

Patty Farrell

Patricia "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, send his parents into a rage. 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 adaptions 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 played by Laine MacNeil.

Heather Hills

Heather Hills is the attractive elder sister of Holly Elizabeth Hills, with whom Rodrick is infatuated. A minor character in the books, but starring as 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 Crossland High School with Rodrick, she has had several minor occupations throughout the course of 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. Similar to her younger sister, Holly, Heather's personality and role is further enhanced in the only film adaption in which she has appeared, Diary of a Wimpy Kid: Dog Days. In a modification of the events of the books, she is depicted as the oldest daughter of the Hills family. She is spoiled, obnoxious, rude, cold-hearted, demanding, mistreating her family and acquaintances. Plus, she proves to be even worse than Rodrick. Lovelorn, Rodrick Heffley and his band are hired to perform at Heather's ostentatious upcoming sixteenth birthday party, and, in an attempt to earn her admiration, Rodrick winds up messing up the celebration and decorations during a boisterous and substandard performance of Justin Bieber's "Baby", which makes Heather very upset and the party ends in disaster. Heather has a slight reference to the behavior of the Carnotaur from Disney's "Dinosaur (film)".

Albert Sandy

Albert Sandy is a minor character, who talks often about rumors he has heard. The validity of his statements are unconfirmed. One of the statement which was not confirmed by Greg was when Albert told him that "it was practically impossible for a girl to fart". Greg knew that it was not true because when his mom hugged Aunt Dorothy on Christmas Eve she farted.

Albert has appeared in The Last Straw, The Ugly Truth, Old School, and Double Down.

Mr. Ira

Only appearing in Diary of a Wimpy Kid, Mr. Ira is a teacher at Greg's middle school who is on the school newspaper adult staff, and enlists a replacement comic strip for the newspaper. He was made fun of in a comic strip entitled Dumb Teachers, and later bowdlerises Greg's Creighton the Cretin comic. He does not do the same with Rowley's Zoo-Wee Mama strip, much to Greg's chagrin.

The Snellas

First appearing in The Last Straw, 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. 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 records the action on his camcorder.

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 underoos hanging off a tree 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. 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, it is revealed a man named Mr. Alexander moved into the Snellas' house.

Scotty Douglas

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. In the tryouts, Greg messes up the act so badly they are the only ones not to make the auditions.

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 (who is supposed to be ugly). 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.

Mr. Underwood

Mr. Underwood is Greg's Phys Ed coach. In the film series, he is named Coach Malone.

Bill Walter

Bill Walter is a 35-year-old high school drop out, and professional singer, who has a rude attitude. 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 the main 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. He also makes an appearance with Rodrick at the beginning at the roller rink. In the book Greg describes him as unemployed still living with his parents even though he is 35 years old. 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 whom Greg has a crush on. Greg 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 says Dr. Kagan is scary and evil and that he never fools around. He has sharp metal tools and never smiles — not even when his picture is taken. He also has billboards on the highway with ads that freak Greg out. His motto is, "Bad oral health is nothing to smile about."

Dr. Kagan makes a brief appearance in Double Down when Greg compares him to a book he read called Spineticklers #67: My Dentist is The Devil.

Lenwood Heath

Lenwood Heath only appears in The Last Straw. He is a rebellious teenager, who was Greg's father'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. In the Dog Days film, he is portrayed by Tom Stevens, and is seen working as a lifeguard at the pool the Heffleys are attending.

Jordan Jury

Only appearing in The Ugly Truth, Jordan Jury is a popular boy in a grade above Greg, who always has blowout parties. He invites Greg and Rowley to his latest one, but Greg cannot not go because of his Uncle Gary's fourth wedding. He finds out later that the only reason Jordan wanted kids in Greg's grade at the party was to use them as servants.

Angie Steadman

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, calling it an "intellectual wasteland." 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. Greg later tells the whole school he ate the cheese instead of Rowley and she compliments and accepts him. In the film, she is portrayed by Chloë Grace Moretz.

Pete Hosey

Pete Hosey is the leader of the teenagers who attacked Greg and Rowley on Halloween. He is the secondary 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.

The Warrens

Although his family is vaguely referenced in the books, the Warren's are what got Frank thinking of making Greg more manly. 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 the secondary antagonist, and is shown to be a neighbor of the Heffley's. He had a childhood rivalry with Frank, that they appear to have gotten over as adults. Greg finds out that Stan has been making fun of his father behind his back and comes up with an elaborate prank to get back at him.

The Beardos

Only appearing in The Long Haul, the Beardos are the main antagonists of the book. They are a couple with three sons. The Heffleys indirectly meet them during their road trip, though only Greg knows who they are. Their first encounter is at a motel, where Greg angrily berates one of the Beardo children, who then tells his father on him, causing Greg to fear running into them again. Greg and his family are convinced that the Beardos have stolen their luggage and belongings at a place they both attended called "Soak Central." They try to track them down though it was revealed at the end that Greg actually had the key to their locker in Soak Central, and that he got the number wrong. Their belongings were actually there. The Beardos were known for driving a purple van, similar to the Heffleys' minivan. The family's real surname is unknown, as Greg himself does not who they are. It is likely he dubbed them this because of the patriarch's noticeably long beard.
