Heffley family

    Greg Heffley
Played by: Zachary Gordon (1-3), Jason Drucker (4)

  • Absurd Phobia: Greg admits that he developed a fear of puzzles, ever since he opened a puzzle box filled with crickets.
  • Accidental Hero: He shovels the walk to the soup kitchen in Cabin Fever causing poor people to be able to eat there, but he didn't even know it was a soup kitchen in the first place. He just wanted to find the letter he had sent to the church.
  • Accidental Pervert: In The Getaway, Greg accidentally steps onto a nude beach. He ends up paying for it.
  • Adaptational Nice Guy: He's considerably more sympathetic and less abrasive in the films. They also make his not-so-nice moments (his prank on Chirag, throwing apples at Patty) more justified by the situations and the other's Jerkass attitude towards him, while in the books both pranks were made basically For the Evulz (Patty was never mean to Greg in the books like she was in the movies). Although in the first film he's still kind of a Jerkass like his book counterpart, in the sequels he becomes nicer and even his bad treatment of Rowley is downplayed.
  • Adorkable: Sure, he's a jerk, but he just wants to fit in with the others. D'aww.
  • Aesop Amnesia: You expect him to learn his learn and stop trying to do stupid things that always end up flying right back in his face? Not a chance.
  • Ambiguous Disorder: Seems to display some combination of:
    • Narcissism: Frequently blame-shifts, is a serious Attention Whore, and is somewhat self-righteous.
    • OCD: Bluntly refuses to use a towel that was used once by someone else, wear other people's clothes, and feels the need to wash his face after being kissed. He also doesn't go in the ocean because marine life pees in it.
    • Sociopathy: Frequently sees to it that Rowley takes the fall for his antics, plays any number of physical tricks on Rowley, and is rather selfish and narcissistic. That said, he's still got empathy.
    • Truman Show Plot: Outright admits in Double Down that he watched a production similar to the origin of the trope's name, and has done otherwise random things to appease the "viewers" of his "show," up to and including a nonsensical Catch-Phrasenote  since then. He also treated Manny's birth with disdain, knowing that introducing cute characters are often used as a saving throw to boost ratings at the last minute.
  • Anti-Role Model: Jeff Kinney, author of the books, describes Greg as this in an interview.
    Interviewer: Is Greg a good role model?
    Jeff Kinney: No. In fact, you should do the opposite of everything Greg does.
  • Attention Whore: He always tries to gain attention and respect at school.
  • Big Brother Bully: In one of the books, Greg explicitly says he had intended to become this to Manny and treat Manny the same way Rodrick treats him. But he could never really do it, mainly because he can't get away with a thing with Manny, due to his parents being extremely protective of him.
  • Book Dumb: He's not stupid, but he's a slacker who receives bad grades.
  • Brilliant, but Lazy: Eventually, he did catch up on his grades...but he's still lazy.
  • Butt-Monkey: Let's see, he's constantly getting bullied by his older brother Rodrick, most of his attempts to "look cool" backfire horribly and his little brother Manny is a total brat who got him in trouble more than once.
  • Cain and Abel: Abel to Rodrick's Cain. Greg is no saint, but while Greg is a cowardly sell-out, Rodrick is an active sadist who delights in tormenting others. Their relationship can be seen as a sort of Sensitive Guy and Manly Man dynamic played up to the worst extremes.
  • Can't Get Away with Nuthin':
    • Whenever he tries to hide his misdeeds (starting the "Invisible Chirag" game, or failing his duties in the Safety Patrol and blaming Rowley for it), he's always eventually found out and punished.
    • Averted, however, in one incident in a flashback when he wrote exactly-what-he-thought-of-them Valentine's Day cards to everyone in his class, some of which were mean, and the teacher never found out he did it.
  • Casanova Wannabe: Often attempts to get with various girls, but he's so bad at it that it ends up that the girls in question never even realize he exists or he ends up looking like a perverted loser in front of them.
  • Character Development:
    • You can tell he's matured a great deal by the end of Hard Luck. It sticks The Long Haul where his misfortune isn't a result of karma as it is simple bad luck.
    • In the tenth book when the town unplugs for the weekend, instead of concocting a scheme to get around it, Greg intends to sit it out with a bunch of comics.
    • In the tenth book, Greg tries to take the camping trip seriously. Unfortunately because he's with the leftovers cabin, he's left to deal with less mature cabin-mates.
  • Charlie Brown Baldness: How he draws himself.
  • The Chew Toy: He could give Charlie Brown and Al Bundy a run for their money. The main difference is that Greg pretty much deserves it.
  • Comedic Sociopathy: This and Greg's reaction to it is from where most of the books' humor derives. Less so later on, though.
  • Companion Cube: One Christmas, Mom got him a baby doll named Alfredo which he became extremely attached to until he lost the doll (actually, his Dad took him and hid him). So Greg replaced Alfrendo with a grapefruit that he took care of in the same manner for the next three months.
  • Cool Loser: Subverted. Greg wants to be seen as such by others (the reader included), but most will tell you that Greg is a dork.
  • Deadpan Snarker: Considering that he is the narrator and his personality, this isn't too surprising.
  • Dirty Coward: Greg lives up to the "wimpy" part of the title of the series in many ways. He's fine with letting Rowley take the blame for scaring kindergarteners in the first book when it was Greg who did it in the first place. Another example is in "Old School". After being caught trying to flee with Frew and Billy, Greg instantly blames it all on Billy to get out of trouble. He admits himself that "when Heffleys get in trouble, Heffleys RUN."
  • Embarrassing Nickname: "Bubby" from Manny. Greg goes to extreme lengths to keep anyone from learning about that nickname.
  • Everyone Has Standards: Sure, he's a gigantic narcissistic dork, but he really hated how the Hero Points scheme was ruined by two dropouts who photocopied the sheets, resulting in the teachers becoming suspicious and eventually landing a genuine Nice Guy in detention, who earned his points legitimately and didn't buy them. And he refuses to buy an old science project from the same two guys, as he knows that it's not only going to land him in jail, it's stealing from everyone. Finally, when he manages to find the diamond ring that Mom's family nearly came to blows over, he hides it so a conflict like that can't happen again for a while.
  • Generation Xerox: In The Ugly Truth, it turns out that Greg looks exactly like Frank's cousin, Terrence in the latter's youth. He's not happy about it.
  • Good Is Not Nice: He's the complete opposite of Rowley, who's nicer than he is, but a complete idiot.
  • Heroic Comedic Sociopath: Greg is not a good person, no matter what anyone tells you. The books are funny because of how much of a jerk Greg is, and while he does have an occassional Pet the Dog moment, at the end of the day Greg is Exactly What It Says on the Tin - A Wimpy Kid.
  • Hilariously Abusive Childhood: Rodrick is constantly bullying him, but they're mostly portrayed as funny. Downplayed as it is not abuse per se. Also, Greg is not exactly the best person himself...
  • Hopeless Suitor: Greg's crush on Holly, at least in the books. In the films, it's implied she may like him, too. By the end of the third book, he gets mad and vents about her in his diary. Come the 8th book, though, and as it turns out, he still wants to marry her when he grows older.
  • Hypocrite Has a Point: Greg's consistent description of Rodrick as a jerk is rather hypocritical in light of his own behavior and his treatment of Rowley. It's also completely truthful, seeing as how Rodrick is a Big Brother Bully with a perchant for crass jokes and petty schemes.
  • Idiot Hero: Although he constantly insults his classmates for being "neanderthals", he himself is not much better, often displaying such a lack of basic knowledge and logic that it can be hard to root for him sometimes.
  • If I Were a Rich Man: In the books he often fantasizes about being rich and famous.
  • I Just Want to Be Special: Or popular.
  • It's All About Me: Greg always pushing Rowley to do things his way.
  • Jerkass: When he and Rowley often try to accomplish tasks together, he usually makes him do all of the work. Also, there's his treatment of Chirag Gupta.
  • Jerk with a Heart of Gold: He has his moments, notably in Cabin Fever where when Rowley anonymously snitches on Greg for accidentally vandalizing the school, he doesn't pull Rowley into it and takes the punishment by himself. He also comforts Rowley after a particularly cruel breakup, decides to hide a diamond ring worth millions so his mom's family can't tear each other apart again, is genuinely furious when a Nice Guy gets landed in detention, and utterly disgusted at how a bunch of dropouts in Hard Luck stole thousands and thousands of science projects and ruined the Hero Points scheme all for a quick buck (although he did something very similar before).
  • Kids Are Cruel: He can sometimes be pretty mean to Rowley.
  • Knight in Sour Armor: He'll help. There just has to be no other choice. Less so later on though.
  • Large Ham: He has his hammy scenes, often in the movies.
  • Lean and Mean: In contrast to his friend Rowley who is wide and much nicer.
  • Loser Protagonist: Our protagonist here is an underachieving dork who completely fails at romance.
  • Middle Child Syndrome: Rodrick frequently bullies him and gets away with it through intimidation and covering his tracks. Meanwhile, Manny makes himself a pest, but Greg can't do anything to him without getting into trouble with his parents.
  • Never My Fault: Typically he is looking to find a scapegoat to blame, and very few times he admits being wrong.
  • Nominal Hero: Not particularly noble to begin with, and most of the time he only looks out for himself. But he is capable of correcting his wrongs in the end, if only out of guilt.
  • Not So Different: From Rodrick. Both are selfish, have a high opinion of themselves despite not having much to boast about, neither does well in school, both are lazy, indoor types who doesn't have much interest in sports (much to their father's annoyance), and both are bad with romances.
  • Perpetual Frowner: His general facial expression in the books is a frown.
  • Potty Emergency: In The Long Haul and The Last Straw.
  • Potty Failure: He used to wet the bed when he was eight.
  • Sensitive Guy and Manly Man: The Manly Man (Jerkass Casanova Wannabe) to Rowley's Sensitive Guy (childish and naive Nice Guy).
  • The Slacker: Not as much as his brother, but he's still very lazy, and not just when it comes to school. When he hangs out with Rowley, he usually makes his friend do all of the work.
  • Small Name, Big Ego: He's full of himself, being confident of becoming rich and famous when he grows up. In fact, one of the reasons he starts keeping a diary is so that he can have a record of his life for people to admire when he becomes famous.
    Imaginary male reporter: Gregory! Tell us about your childhood!
    Imaginary female reporter: Were you always so smart and handsome?
    Imaginary Greg: Here's my journal. Now, shoo, shoo.
  • Sociopathic Hero: At his absolute worst.
  • Spiders Are Scary: Greg has serious arachnophobia as shown in The Getaway. He is completely panicked when he meets a tarantula.
  • Strong Family Resemblance: He looks like Rodrick a lot in the films.
  • Super OCD: A minor running gag is his fear of germs or anything he considers unhygienic. He scrubs his face with antibacterial wipes (and a curtain) after being kissed by relatives, refuses to swim in the ocean because he knows aquatic animals pee in it, and won't touch his mom's potato salad because it's served in the same bowl she gives him and his brothers to throw up in when they're sick.
  • Sweet Tooth: Falls asleep in class if he doesn't get a sugary snack in his lunch.
  • This Loser Is You: Readers are clearly supposed to identify with Greg, who is often the passive victim of the torment and ridicule he receives.
  • Token Good Teammate: Downplayed, at least of the children (Susan's easily the one of the entire family). He's far from a nice kid, but he's surprisingly far less mean-spirited than both of his brothers (the elder is a huge Big Brother Bully and the younger is a horribly spoiled child who isn't hesitant in leaving his family to die in a blizzard for no good reason (obliviously or not)). In fact, this actually makes it obvious in which he gets his jerkish behavior from (from Roderick, at least).
  • Took a Level in Kindness: In the 1st movie, he was a big jerk like in the books, but in the 2nd and 3rd movie, he was more likable (and Holly Hills was also introduced in the second movie, coincidence?).
  • Toxic Friend Influence: To Rowley, at least according to Rowley's parents (they're not entirely wrong...)
  • Unreliable Narrator: He often clearly twists facts to make him look better. But a lot of what he goes through seems plausible.
  • Unsympathetic Comedy Protagonist: Despite his claiming otherwise, he's clearly not the nicest person in the world.
  • Vitriolic Best Buds: With Rowley. Greg supplies all the vitriol, and Rowley is the cheerful, passive one.

    Rodrick Heffley
Played by: Devon Bostick (1-3), Charlie Wright (4)

  • Book Dumb: He lets his father do all his homework, and fails his assignments when he does it on his own.
  • Cain and Abel: Cain to Greg's Abel. Greg is no saint, but it's clear that Rodrick is the meaner one of the two.
  • Character Development: In the books, there's not much to him other than being Greg's tormentor. In the movies, he gets a bit more depth.
  • Cool Big Bro: After a bit of Character Development in the movies.
    • He spends most of the second movie bullying Greg, but in later scenes he starts bonding with him and giving him advice. The whole movie is about their rivalry and the development of their brotherly relationship.
    • He's still one in the third movie. While Greg doesn't look up to him nor thinks he's "cool", they are more or less on good terms (at least, much better than before) and Rodrick is never seen pranking or tormenting his brother.
  • Deadpan Snarker: If there's a sarcastic one-liner to be given, he'll usually deliver it.
    Rodrick: Monkeys don't speak English, stupid.
  • Deuteragonist: In the second movie. The movie even has his name in the title.
  • Dogged Nice Guy: Okay, so "nice guy" might be a bit of a stretch, but when you see him try so hard to win the love of Heather Hills in the 3rd film, only for her to respond with rudeness and a cold personality, it's hard not to feel a bit sorry for him.
  • Dreadful Musician: Zigzagged. Greg doesn't really think much of his music. But then again, Greg doesn't think much of him at all. Frank doesn't like his music either, but Susan does.
  • Dumbass Teenage Son: He's portrayed this way, especially when it comes to his schoolwork.
  • For the Evulz: Why he messes with Greg.
  • Heavy Sleeper: Spends most of his free time sleeping and once slept for almost two days straight.
    Greg: "The only person I know who's better at sleeping than me is Rodrick."
  • Hopeless Suitor: He's smitten with Heather Hills, and tries to win her heart. He fails.
  • Jerkass: He's a rebellious bully who goes out of his way to screw with Greg and defy his parents.
  • Jerk with a Heart of Gold: In the second movie, where he makes peace with Greg and starts being much nicer to him. And finally, in Hard Luck, he and Greg and Dad finally spend some happy family time blowing raspberries at Sweetie.
  • Karma Houdini: He always gets away with bullying Greg.
  • Karma Houdini Warranty: On one occasion his parents ground him for throwing a party while they were away after he did everything in his power to prevent himself from doing so.
  • Kick the Son of a Bitch: Does this unintentionally to Heather, whom he was trying to win over. However, when Greg turned up the volume and effects, Heather's birthday party is ruined and her dress is messed up. Heather is a complete asshole to the main characters, and the destruction of her sweet 16 is fitting punishment for her behavior. You can actually cheer on Rodrick for doing this, jerk he may be.
  • Large Ham: Sometimes in the movies, but averted in the books.
  • Lazy Bum: According to Greg, he's "the king of laziness".
  • Lean and Mean: Very thin, and the meanest one in family (which is really saying something).
  • Metalhead: With aspirations of becoming a big-time musician.
  • Mr. Fanservice: In the movies where he's played by Devon Bostick with a few gratuitous Shirtless Scenes.
  • Never My Fault: the book version of "Rodrick Rules" has the distinction of having it happen twice on one page. When Mom dances during the recording of Rodrick's band session at the talent show, thus depriving him of his chance to show his performance to record companies, Rodrick calls her out. She just responds that he shouldn't play music if he doesn't want people to dance. Rodrick then blames the recording fiasco on Greg for not taping the show for him, only for Greg to reply that he would have done it if Rodrick wasn't such a Jerkass.
  • Not So Different: To Greg. Much like his younger brother, Rodrick has a high opinion of himself, is selfish, lazy, an indoor type who doesn't have much interest in sports (much to their father's annoyance), bad with girls (as seen in the movies), and an underachiever in school.
  • Perpetual Frowner: In the books he's always drawn this way.
  • Serenade Your Lover: In the third movie, Rodrick has a huge crush on Heather Hills, to the point of attempting to serenade her. She wants nothing to do with him.
  • Shirtless Scene: Several in the movies, including the three days and no shower scene.
  • The Slacker: He weaponizes this behavior to "lower people's expectations and surprise them by doing almost nothing at all."

    Manny Heffley
Played by: Connor and Owen Fielding (1-3), Wyatt and Dylan Walters (4)

  • Ambiguous Disorder: His child prodigy tendencies, occasionally OCD (the way he deals with certain food) mixed with his lack of social skills suggest that he may be on the autism spectrum.
  • Annoying Younger Sibling: To Greg and Rodrick. Manny enjoys frustrating and bothering them with his brattiness.
  • Animal Stereotypes: he has the look of "a bucktoothed alligator" according, to the movie diary.
  • Baby Talk: "Wipe my heinie, ploopy!"
  • Bratty Half-Pint: Taken Up to Eleven.
  • Born Lucky: Has much more privileges than his brothers and barely anything bad happens to him, to Greg's annoyance.
  • Berserk Button:
    • If you don't give him what he wants, he will have an utter tantrum.
    • It's revealed in "The Long Haul" that he will go on an utter rage if his nap time is interrupted.
    • Never give him sandwiches cut in halves.
    • You'd better put the mustard on his hotdog across the middle if he asks you to give him a hotdog.
  • Bilingual Bonus: In The Long Haul, he is shown to be fluent in Spanish.
  • Bitch in Sheep's Clothing: Manny acts all nice and sweet around Susan and Frank, but in reality he's a complete brat and the gloves will come off if he doesn't get what he wants.
  • Character Development:
    • Inverted. He seems to just get worse and worse as the books goes on. In the 6th book he nearly MURDERS his entire family over not knowing how to tie his shoes!
    • He makes one small improvement in Hard Luck: he's shown to have made a friend in his preschool class, which suggests that his social skills may be getting better, if nothing else. And he is the only one who can speak Spanish, which leads to getting a ride home in a car that works.
  • Child Prodigy:
    • In Cabin Fever, he figured out how to change the parental controls, hack into Greg's Net Kritterz account, and even switch off most of the electricity.
    • Also showing signs of this by The Long Haul. He can speak perfectly fluent conversational Spanish, understand decimal numbers, and give accurate directions in Spanish to a place that he's only seen once in his life (that, or he figured out how to use the family's GPS, which is impressive by itself).
  • Companion Cube: The remains of his old knit blanket, which he calls "Tingy."
  • Cloudcuckoolander: He has quite the air headed personality.
  • Creepy Child: Played for laughs in book 6, where he steals almost all of the house's supplies and leaves the rest of the family to die during a blizzard. Greg throws out the possibility that Manny was just throwing a tantrum and didn't honestly realize he was endangering anybody, but he's not 100% convinced that's the case.
  • Even Bad Men Love Their Mamas: Out of all the Heffleys, Manny is the closest to Susan.
  • Genius Ditz: He's not exactly the brightest member of the family, but he seems to have extensive knowledge of computers, being that he messed up Greg's Net Kritterz account password in Cabin Fever and changed the settings on the TV. Manny is also shown to be highly fluent in Spanish in The Long Haul.
  • It's All About Me: Has extremely selfish behavior, even for kids his age. This is likely because of his parents spoiling him rotten.
  • Jerkass: Manny is very bratty and spoiled, and throws fits to get what he wants. He even almost starved his family to death in the middle of a blizzard just because nobody taught him to tie his shoes. Manny has a vindictive streak as well; he once ruined Frank's civil war battlefield because the latter threw out his blanket, though to be fair, Frank didn't know it was Manny's blanket.
  • Karma Houdini: He can get away with messing with Greg's stuff solely because Mom and Dad baby him. This gets ridiculous in book 6. He gets away with the events described in the above trope. That's right, he left the family to die during a blizzard, and did not get PUNISHED.
  • Kick the Dog: He left his family to die during a blizzard to ensure his own survival. When Manny went missing for a day, his mother, Susan, found him in his room surrounded by food, water, toys and a space heater. The reason for this? Nobody ever taught him how to tie his own shoes!
  • Momma's Boy: He's clearly Susan's favorite son, probably because he's the youngest.
  • Moral Myopia: He has no qualms with calling Greg a "ploopy", but he gets really upset when Greg does that to him.
  • Nightmare Fuel Station Attendant: After watching a horror movie, Manny draws a picture of a monster, and it even frightens Greg.
  • Nightmare Fuel Coloring Book: Manny accidentally watches a scary movie that Rodrick left in the disk drive, then later makes a scary drawing that Greg notes was enough to give him nightmares.
  • Never My Fault: He blames breaking a plate on his imaginary friend "Johnny Cheddar".
  • Non-Standard Character Design: He has an extremely pronounced upper jaw and prominent buck teeth. Since this is at no point commented on, it's likely a purely artistic matter.
  • No Social Skills: Even for a kid his age. He's so terrified of kids his age that his only friends are imaginary ones. Subverted in Hard Luck.
  • The Quiet One: Averted at the end of The Long Haul in which he has a conversation with two mechanics in fluent Spanish for almost a hour.
  • Spoiled Brat: His parents spoil him so much and let him get away with things that Greg and Rodrick would get in big trouble for. See Karma Houdini above.
  • The Stool Pigeon: Manny has always been a big tattletale since the day he was able to talk. According to Greg, he also told his parents what wrong deeds Greg did before he could talk.
  • Super Ocd: With his food. Never give him sandwich cut in halves (quarters instead); only eats hotdogs with a short line of mustard applied in the middle; poured milk in the bowl first before cereal and he will throw a tantrum.
  • Took a Level in Jerkass: In book 6, he acted noticeably brattier than other books.
  • Troubling Unchildlike Behavior: In the first book, Manny rips out a suggestive picture of a bikini-clad woman reclining on a car hood from one of Rodrick's magazines and takes it to preschool. Mom ends up punishing Rodrick.
  • Ungrateful Bastard: Book 6 has him hoard food and cut off all the power to the house except his room during a blizzard, essentially leaving the family for dead because no one taught how to tie his shoes. After Susan teaches him, he decides he likes having her tie them for him better.
  • Why Did It Have to Be Snakes?: Was afraid of the "Potty Monster" for a time after Uncle Joenote  told him there was a monster in the toilet.
  • Youngest Child Wins: In that Manny winds up getting treated much better than his siblings. It's implied that this is a bit of a cyclical matter, as Gregory used to enjoy a similarly privileged position right until Manny was born..

    Susan Heffley
Played by: Rachael Harris (1-3), Alicia Silverstone (4)

  • Adaptation Name Change: Susan is renamed "Ann" in the online diary.
  • Adorkable: She shows shades of this in the second book when playing Magick and Monsters.
  • Amazingly Embarrassing Parent: She tends to unintentionally humiliate Greg a lot.
  • Blind Without 'Em: In "Cabin Fever" it's shown she cannot see well if her glasses aren't on, and this is a huge problem when Manny breaks her glasses.
  • Doting Parent: To Manny, especially, but she's also shown to be a loving parent to Greg somewhat. She's also soppy to Rodrick and the only one who likes his music.
  • Hidden Depths: She loves dancing to heavy metal music.
  • Horrible Judge of Character: She means well, but doesn't seem to understand any of her children and spoils her youngest son Manny way too much.
  • Misplaced Kindergarten Teacher: She is gleefully oblivious to Greg's unhappiness to any inconvenience she causes him, from inviting Fregley over to play hide n' seek, to making him participate in the school play of The Wizard of Oz, to joining in Greg's "Magick and Monsters" game and completely ignoring the "kill and level up" nature of the game.
  • Moral Guardian: She dislikes violence on any sort of media and will do anything to keep it away from the kids.
  • Nice Girl: While unaware to things around her, she truly wants the best for her family.
  • Opaque Nerd Glasses: In the books. Her eyes are not drawn because of her glasses.
  • Opposites Attract: She's caring and good-natured while her husband Frank is cranky and mean.
  • Parental Favoritism: Towards Manny. She even went all the way from her workplace to his preschool to cut his sandwiches because Manny was throwing a tantrum about his sandwich being cut in halves instead of quarters.
  • Parental Obliviousness: She's apparently unaware of the ongoing Sibling Rivalry between Greg and Rodrick, among other things.
  • The Pirates Who Don't Do Anything: Zig-Zagged. Greg's mom doesn't appear to have a job, but he mentions that she runs an article in the newspaper, and it's implied she might have been a therapist (but one for younger kids if anything) but is implied to go to school. Otherwise... she's not really doing anything.
  • The Pollyanna: Always tries to see the good side of things, even in her Dysfunctional Family.
  • Token Good Teammate: She's the only one who isn't a total Jerkass in the family, although she is pretty oblivious to anything about teens.
  • Wide-Eyed Idealist: Always tries to do good with her family, like bringing them on trips, inviting friends over, and trying to get kids to be more active, but they never ever pan out and always end up making the situation worse for the main character. She still keeps trying anyway.
  • What Does She See in Him?: One's a snarky, Jerkass, grumpy, bumbling dad who hates teenagers, heavy metal, video games and only wants to toughen up his middle child while get rid of his eldest child. The other is a former kindergarten teacher who's a gentle, caring, well-meaning Moral Guardian mother who dances to heavy metal, loves her family for the way they are, only wishes for them to be more like a family, and genuinely tries to do the best for her sons (though it's often wasted effort because of her inability to understand the fact that problems teens face can't really be solved with methods used to solve problems for kindergarteners). They're married.

    Frank Heffley
Played by: Steve Zahn (1-3), Tom Everett Scott (4)

  • Adaptational Nice Guy: In the films, he's actually less strict on his sons than he is in the books.
  • Ascended Extra: The third movie is sort of A Day in the Limelight for him, compared to his role in the first two movies.
  • Amazingly Embarrassing Parent: Often, though not as much as Susan.
  • Bumbling Dad: He acts like he's in his 80s. Not only does he regularly yell "Dagnab you rotten teenagers!", but in the webcomic, he tries to get Classical music playing throughout the town to scare the teenagers away, is apparently teenager phobic, can't figure out how Gregory's game system is even hooked up to the TV, and says people at drive-thrus are idiots...yet he tries to place his order through a garbage can.
  • Berserk Button:
    • Don't wake him up in the middle of the night.
    • Frank HATES rock and roll music.
    • Never mess with his Civil War Battlefield.
    • The entire existence of Li'l Cutie is this for him.
    • Bringing up the time Uncle Gary pranked him on Christmas.
    • The Peachy Breeze commercial is a huge button for Frank.
  • Deadpan Snarker: He isn't really far behind Greg in levels of snarkiness.
  • Irrational Hatred: Rowley once accidentally broke a plate while at the Heffley house. Ever since then, Frank has treated Rowley like a Lethal Klutz ever since.
  • Jerkass: He's a bit of an asshole to his sons, and frequently forces them to engage in activities they dislike (i.e. sports).
  • Jerkass Has a Point: His fears that Rodrick will grow up to be a Basement-Dweller aren't too far off.
  • Jerk with a Heart of Gold: Frank did go to scout meetings with Greg, and bought tickets to the baseball game so the two could bond (sadly both events backfired horribly). He also bought Greg an expensive weights set for Christmas (that Greg then never used). In the movies he's still somewhat strict, but hardly a jerk.
  • Large Ham: In the movies, he's pretty hammy.
  • Not So Different: Old School reveals that when Frank was Greg's age he made up Silas Scratch so he could hide off in an old maintenance shed with a shower and heating to get away from the camp, something he does along with Greg in the present.
  • Perpetual Frowner: Does not smile very much. It's very obvious in the books.
  • Serious Business: His toy American Civil War battlefield. Respect it.
  • Sweet Tooth: He's addicted to snack foods to the point he'll frame his sons for taking them.
  • The Stoic: Is not a terribly emotional person.
  • Trademark Favorite Food: Anything with sugar in it.
  • The Unreveal: It's never shown what he does for a job.
  • What, Exactly, Is His Job?: His job is never revealed.
  • Why Couldn't You Be Different?: He wishes his sons to be more manly because the sons of his boss are all sports jocks.

Greg's Classmates

    Rowley Jefferson
Played by: Robert Capron (1-3), Owen Asztalos (4)

  • Adorkable: A slightly-dim Kiddie Kid who doesn't have a mean bone in his body.
  • Ambiguously Gay: Sometimes, Rowley's actions are a bit suspect, especially with Greg. You'd think that a 12-year old boy would realize that sharing a "Best Friends" locket (in the shape of a heart) with another 12-year old boy would be weird or realize that being a fan of a rather effeminate pop singer isn't exactly manly. It could be argued that he's just completely unaware of these things considering that he is a Cloudcuckoolander and is completely sheltered, however. However, he does hook up with Abigail.
  • Born Lucky: Although he can be a Butt-Monkey on occasion, he has much better luck than Greg and even got a girlfriend at one point.
  • Bumbling Sidekick: Greg's bumbling annoying best friend.
  • Butt-Monkey: At times, mostly as an indirect result of Greg's actions.
  • Character Development: Throughout the books, Rowley learns to stand up for himself and grow a spine instead of blindly following people.
  • Clueless Chick Magnet: He doesn't seem to be all that interested in girls, yet in Rodrick Rules he manages to socialize with some of the most popular girls in his year.
  • Cloudcuckoolander: Rowley acts like he's "out of it" sometimes.
  • The Ditz: He often says and does ignorant things.
  • Deuteragonist: Of the book series and the first movie.
  • Dumbass Has a Point: The very few times Rowley calls out Greg for being unfair, he's completely right.
  • Extreme Doormat: He usually just goes along with Greg's ideas, even though Greg often uses him and makes him do all of the work.
  • Fat and Skinny: The fat to Greg's skinny.
  • Fat Best Friend: To Greg.
  • Fat Comic Relief: He's a little wide around the edges, and is a comedic relief character.
  • Fat Idiot: Downplayed, as he is chubby but not so fat and he is ditzy, but not idiotic.
  • Flanderization: Rowley was simply gullible and slow on the uptake before becoming the Kiddie Kid.
  • Foil: To Greg. Greg is skinny, cynical, jerkass and Butt-Monkey, while Rowley is chubby, optimistic, nice, and Born Lucky.
  • Kavorka Man: He has much more success with girls than Greg does, which can probably be attributed to his friendly, easy-going nature and his dorky charm.
  • Kiddie Kid: He's very childish for his age, and in one of his birthday parties, all his guests aside from Greg are six-year-olds (albeit because they were all from his karate class.)
  • Kindhearted Simpleton: He means well for the most part.
  • The Lancer: As Greg's sidekick.
  • Momma's Boy: His mother is overly loving and protective towards him, especially seen in the third film. This may explain Rowley's Kiddie Kid behaviour.
  • Nice Guy: In sharp contrast to his friend Greg.
  • Only Child Syndrome: In the fourth book and in the webcomic, when Rowley has a nightmare, his parents rush to his aid and ignore that Greg was thrown on his face.
  • Perpetual Smiler: In contrast to Greg, he almost always is smiling.
  • The Pollyanna: He's much more optimistic than Greg.
  • Sensitive Guy and Manly Man: The Sensitive Guy (childish and naive Nice Guy) to Greg's Manly Man (Jerkass Casanova Wannabe).
  • The Southpaw: An Informed Attribute. Greg mentions that he's left handed when he describes the time Rowley broke his right hand.
  • Status Quo Is God: No matter how deep the rift between him and Greg gets, they always come back together in the end.
  • Straw Loser: Being fat and childish, he comes off as even more pathetic than Greg. Subverted in that Rowley is better liked by his classmates than Greg is.
  • Stupid Good: Good-hearted but not very bright.
  • Terrible Artist: Greg describes Rowley as a terrible artist in the first book, when Rowley reveals his art style.
    Greg: And believe it or not, Rowley's drawing skills are worse than his writing skills.

    Chirag Gupta
Played by: Karan Brar

  • Adaptational Jerkass: In the books Chirag's hostility towards Greg is very well deserved while in the movies he's extremely condescending, and arrogant.
  • Ascended Extra: He's only occasionally mentioned in the books as one of Greg's classmates. In the movies, he gets a more active role, being the occasional Mr. Exposition.

Played by: Grayson Russell

    Angie Steadman
Played by: Chloe Moretz

A movie-only character.

  • Academic Athlete: Class president and teacher's pet, she's also great at wrestling, soccer and tennis.
  • Adaptational Badass: In the movies, she's a stellar athlete. However, she's usually only shown besting Greg (the self-described "wimpy kid") so it could be chalked up to him not being good at sports.
  • Adaptational Villainy: In the books, at worst Patty is a teacher's pet and is only implied to be an Attention Whore — in fact, she's never directly interacted with Gregnote  — while in the movies, she's a nasty two-faced egomaniac who goes out of her way to make antagonize Greg.

  • Meganekko: Wears glasses in the books.

  • Jerk Jock: How Greg puts it, but it's mostly an Informed Attribute.

    Alex Aruda 

Other Characters

    Robert Jefferson 
Played by: Alf Humphries

Rowley's father, who doesn't like Greg and finds him to be a bad influence.

  • Berserk Button: Has a few, such as telling him he smells like a woman.
  • Disproportionate Retribution:
    • In the books he got Greg banned from the country club, likely because he can't take being criticized.
    • In the first book and the movie Greg tells Rowley in a "secret language" that Mr. Jefferson smells like a woman when he was in hearing range. Mr. Jefferson responded by kicking Greg out of the Jeffersons' house. It's worse when you realize that with Greg at his age, smelling like a woman probably means smelling like flowers.
  • Jerkass: He's an extremely strict father (far more so than Frank Heffley), and a very rude person in general. In the tenth book, when chaperones the cabin Greg ends up in, he is particularly keen to pin any trouble on him. The thing is that Greg is well aware of how Mr Jefferson feels about him and goes out of his way not to do anything to cause trouble, and it's his less mature cabin-mates who cause the trouble.
  • Moral Guardian: Thinks that Greg is a bad influence to his son Rowley and doesn't like to see Greg around. To be fair, Greg probably is a bad influence, at least in the books.
    • Also, he doesn't allow video games which have any kind of violence in them, which means Rowley can only play racing games. Greg finds a loophole by storing video games with violence in Edutainment Game cases.
  • Overprotective Dad: Overly protective of his son Rowley.
  • Papa Wolf: To Rowley.

    Bill Walter
Played by: Fran Kranz

  • Adaptational Attractiveness: Quite a bit more handsome in the movie than he is in the book, where he's depicted as a hairy middle-aged man with a beer gut.
  • Adaptational Jerkass: In the books, he's merely annoying, making Rodrick's parents fear that their son might take after him.
  • Basement-Dweller: He's a 30+ something man who still lives with his parents.
  • Cool Loser: Well, Rodrick thinks he's cool, even though he's an unemployed Basement-Dweller.
  • Jerkass: In the film, he invites himself over to the Heffleys' for dinner, and then replaces Rodrick with another drummer when he's grounded from performing in the talent show.
  • The Rockstar: He's the lead singer of Rodrick's band "Loded Diper".

    Heather Hills
Played by: Melissa Roxburgh

Holly's sister. Not much is said about her in the books, so most of these tropes apply to her in the films.

  • Adaptation Name Change: Named "Lori Matthews" in the online diary.
  • Adaptational Jerkass: In the books we don't learn much about her but what we did learn never implied she was the snobby stuck-up bitch she is in the movies.
  • Alliterative Name: Heather Hills.
  • Alpha Bitch: She's pretty, rich and popular, and uses this as an excuse to treat everyone, including her sister, like dirt.
  • Big Bad Ensemble: One of the main antagonists of the third movie along with Stan Warren.
  • Big Sister Bully: To her little sister Holly. She's rude to everyone, anyway.
  • Cain and Abel: A female version of this. She is the Cain to Holly's Abel.
  • Distaff Counterpart: Of Rodrick, not to mention an even worse one at that. Greg describes her as "Rodrick in a dress".
  • Evil Counterpart: To Holly. Both are beautiful blonde rich girls, and one of the Heffley brothers has a crush on each of them. The difference? Holly is a nice and sweet girl who deserves her popularity, while Heather is a complete and utter bitch.
  • Eviler Than Thou: Not even Rodrick can stand on equal grounds with her.
  • Jerkass: She's a self-centered bitch who refuses to help others even while on lifeguard duty, and frequently stops Holly from being nice to Greg because she'd rather her help out in her Sweet Sixteenth celebration.
  • Kick the Dog: Several times. In her first appearance in the third movie, she runs over Rodrick's feet with her car when he tried to flirt with her. Then she is shown to turn away a little girl asking her questions about the Country Club schedule even though she's a lifeguard.
  • Laser-Guided Karma: It was almost nice to see her humiliated when her beloved party is ruined and she ended up covered in chocolate. Even her sister Holly said she was happy and that she thought that Heather fairly deserved it.
  • Lack of Empathy: Yeah, of all the Jerkasses in the trilogy, Heather has no redeeming qualities whatsoever.
  • Smoking Is Not Cool: In the online diary, she got fired from her babysitting job when Mr. Jefferson caught her smoking behind the house.
  • Spoiled Brat: In contrast to her sister's Spoiled Sweet.
  • Sibling Yin-Yang: Holly is good-hearted and affable, but Heather is selfish and stuck up.

    Uncle Charlie

  • Adaptation Name Change: In the webcomic, he was named Freddie.
  • Attention Whore: He gives Greg a framed photo of himself for Christmas!
  • Cool Uncle: Greg refers to him as his secret Christmas weapon, since he'll get Greg any gift he wants (although whether he gets Greg the right gift is another matter entirely).
