Characters: Diary of a Wimpy Kid

Greg Heffley
Played by: Zachary Gordon

  • Adorkable: Sure, he's a jerk, but he just wants to fit in with the others. D'aww.
  • 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.
  • Attention Whore: He always tries to gain attention and respect at school.
  • Book Dumb: He's not stupid, but he's a slacker who receives bad grades.
  • Butt Monkey: Let's see, he's constantly getting bullied by his older brother, and most of his attempts to "look cool" backfires horribly.
  • Cain and Abel: Abel to Rodrick's Cain. Greg is no saint, but it's clear that Rodrick is the meaner one of the two.
  • 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 mean Valentine's Day cards to everyone in his class and the teacher never found out he did it.
  • Charlie Brown Baldness: How he draws himself.
  • The Chew Toy: He could give Charlie Brown and Al Bundy a run for their money.
  • Companion Cube: One Christmas, Mom got him a baby doll named Alfredo which he became extremely attached to until he lost it (actually, his Dad took it and hid it). So he replaced it with a grapefruit that he took care of in the same manner for the next 3 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.
  • Generation Xerox: In The Ugly Truth, it turns out that Greg looks exactly like Frank's cousin, Terrence. He's not happy about it.
  • Hilariously Abusive Childhood: Rodrick is constantly bullying him, but they're mostly portrayed as funny.
  • 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 and pelting Patty Farrell with apples.
  • 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.
  • Kids Are Cruel: He can sometimes be pretty mean to Rowley.
  • Lean and Mean: In contrast to his friend Rowley who is overweight 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, while Manny makes himself a pest but Greg can't do anything to him without getting into trouble with his parents.
  • Mr. Imagination: In the books he often fantasizes about being rich and famous.
  • 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 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.
  • 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. On the other hand, Greg's friends Rowley and Fregley are even more pathetic.
  • 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

  • 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.
  • Casanova Wannabe: He's smitten with Heather Hills, and tries to win her heart. He fails.
  • 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: For most of the second movie, after he and Greg start getting along.
  • 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: Greg doesn't really think much of his music. But then again, Greg doesn't think much of him at all.
  • 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."
  • 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 movies, where he makes peace with Greg and starts being much nicer to him.
  • Karma Houdini: Subverted on one occasion when 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, 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.
  • Lean and Mean: Very thin, and the meanest one in family (which is really saying something).
  • Mr. Fanservice: In the movies where he's played by Devon Bostick with a few gratuitous Shirtless Scenes.
  • Not So Different: In the movies to Greg. Lets make a comparison; Rodrick has a high opinion of himself, is bad with girls, an underachiever in school, and lacks talent at the one thing he thinks makes himself cool (being a musician).
  • Secondary Character Title: In the second movie "Diary of a Wimpy Kid: Rodrick Rules". He has a very big role, but Greg is still the main character.
  • Shirtless Scene: "Three days. No shower. Smell the love."

Rowley Jefferson
Played by: Robert Capron

  • 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.
  • 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.
  • The Ditz: He often says and does idiotic 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: He's the fat and dumb fall guy to Greg's skinny straight man persona.
  • Fat Best Friend: To Greg.
  • Kavorka Man: He gets a lot of girls to like him over the course of the books. Including Holly Hills.
  • 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.
  • Kindhearted Simpleton: For the most part he means well.
  • 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: Nicer than Greg, at least.
  • 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.

Manny Heffley
Played by: Connor and Owen Fielding

  • Annoying Younger Sibling: No kidding. He would not survive in most families without being physically tortured as retribution; add in Parental Favoritism and you got the perfect recipe for Cain and Abel.
  • Baby Talk: "Wipe my heinie, Ploopy!"
  • Companion Cube: The remains of his old knit blanket, which he calls "Tingy."
  • Enfant Terrible: Played for laughs in book 6, where he steals supplies and leaves the rest of the family for dead 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.
  • 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 for dead during a blizzard, and didn't get punished.
  • Kick the Dog: He left his family for dead 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.
  • No Social Skills: Even for a kid his age. He's so terrified of kids his age that his only friends are imaginary ones.
  • 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 very much and les him get away with things that Greg and Rodrick would get in big trouble for. See Karma Houdini above.
  • Youngest Child Wins: Only in that Manny winds up getting treated much better than his siblings.

Mom (Susan Heffley)
Played by: Rachael Harris

  • Hidden Depths: She loves dancing to heavy metal music.
  • 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.
  • Opaque Nerd Glasses: In the books. Her eyes are not drawn because of her glasses.
  • 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 on-going 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.
  • Token Good Teammate: She's the only one who isn't a total Jerkass in the family.
  • 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, the only thing wishing for them to be is more like a family and genuinely tries to do the best for her sons (though it's often lost 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.

Dad (Frank Heffley)
Played by: Steve Zahn

  • Bumbling Dad: He acts like he's in his 80s. Not only does he regularly yell "Dagnabbed 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.
  • Deadpan Snarker: He isn't really far behind Greg in levels of snarkiness.
  • Jerkass: He's a bit of an asshole to his sons, and frequently forces them to engage in activities they dislike (i.e. sports).
  • 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.

Chirag Gupta
Played by: Karan Brar

  • 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.
  • Butt Monkey: He's sometimes picked on because of his short height. Also in the second movie, when Greg plays the "Invisible Chirag" joke on him.
  • Funny Foreigner: The movie states that he is from India.
  • Mr. Exposition: Tells Greg and Rowley about the Cheese in the 1st movie and Holly Hills in the 2nd.
  • The Napoleon: He's the shortest kid in class, but Greg mentions that he can punch hard.
  • The Rival: To Greg in the 2nd film. Both of them like Holly Hills.
  • Stalker with a Crush: "What? I Googled her."
  • Token Minority: He's the only non-white character in the series
  • Wholesome Crossdresser: Briefly disguises as Holly to make fun of Greg in the 2nd movie.

Holly Hills
Played by: Peyton R. List

  • The Ace: Gender-flipped variant. Summed up by Chirag - "She is an all-star soccer player, has done professional modeling and was her 6th grade class president. ...What? I Googled her!"
  • Alliterative Name: Holly Hills
  • All Love Is Unrequited: Greg's crush on her, at least in the books. In the films, it's implied she may like him, too.
  • Ascended Extra: Her character and personality were hardly explored in the books, but she gets a bigger role in the movies.
  • Hair of Gold, Heart of Gold: In the film version, she's portrayed as a very Nice Girl. She willingly hangs out with "class losers" like Greg and Rowley, helps out in the Country club to teach children tennis, and later offers to teach Greg and Rowley.
  • Official Couple: With Greg, at the end of the third movie
  • Satellite Love Interest: More so in the books. In the second movie, she gets more personality.
  • Spoiled Sweet: In the films, in stark contrast to her sister.

Played by: Grayson Russell

Angie Steadman
Played by: Chloe Moretz

A movie-only character.

  • Big Sister Mentor: Tries to be this to Greg and Rowley, but Greg won't listen to her.
  • Canon Foreigner: Only appears in the first movie.
  • Cool Loser: She's intelligent and pretty, but dislikes school and other students.
  • Deadpan Snarker: "This place is an intellectual wasteland."
  • Flat Character: Basically. Not even referred to in the second movie. She's just basically there to sort of "guide" Greg and Rowley through their first year of middle school.
  • Hot Scoop: She's a very pretty school journalist.

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.

  • Alliterative Name: Heather Hills
  • All Love Is Unrequited: Rodrick has a huge crush on her, to the point of attempting to serenade her. She wants nothing to do with him.
  • 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.
  • Blondes Are Evil: In contrast to her sister's Hair of Gold, Heart of Gold.
  • 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".
  • Eviler Than Thou: Not even Rodrick can stand on equal grounds with her.
  • Foil: 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.
  • 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.
  • Spoiled Brat: In contrast to her sister's Spoiled Sweet.

Patty Farrell
Played by: Laine MacNeil

A girl at Greg's school. Patty and Greg aren't the best friends, in fact they are deathly enemies.
  • Academic Alpha Bitch: In the movies. She is the class president, and seems to abuse her power.
  • Academic Athlete: Class president and teacher's pet, she's also good at wrestling, soccer and tennis.
  • Ascended Extra: Has a bigger role in the movies (especially the first one) than in the books.
  • Big Bad Ensemble: One of the main antagonists in the first movie, along with Rodrick and Pete Hosey.
  • Disproportionate Retribution: In the movie, she is brutally vindictive to Greg, for insulting her in kindergarten.
  • Girlish Pigtails: Subverted. Even though her hair is tied in pigtails, she is not at all girly.
  • Karma Houdini: She didn't get punished for yelling at the drama teacher, threatening to ruin her life unless she played Dorthy in the Wizard Of Oz school play. She also goes psycho on Greg when he is unable to sing in the middle of the play, and yet she doesn't get punished.
  • Meganekko: Wears glasses in the books.
  • The Rival: She is Greg's worst enemy.
  • Spoiled Brat: Her mother in the movies is the head of the PTA, so she gets what she wants from the teachers.
  • Teacher's Pet: She mentions her Mom's Responsibility to fire a teacher if she doesn't get what she wants.

Robert Jefferson
Played by: Alf Humphries

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

  • Berserk Button: Greg has a habit of pressing his.
  • 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 woman when he was in hearing range Greg was kicked out and it's worse when you realize that with Greg, smelling like a woman probably means smelling like flowers.
  • Moral Guardian: Thinks that Greg is a bad influence to his son Rowley and doesn't like to see Greg around.

Bill Walter
Played by: Fran Kranz

  • Adaptational Villainy: 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.

Bryce Anderson
Played by: Owen Best

  • The Ace: According to the second movie, Rowley calls him an athlete, whose soccer skills are only bested by Holly.
  • Crazy-Prepared: When he ran a restaurant of sorts at his house, he had one of his cronies guard the area with a pellet gun.
  • Gang of Bullies: Has a group of goons under his employ who worked at his restaurant. The "bullies" part might be subverted since they never actually bullied anyone (that we know of).
  • School Idol: Most of the girls at Greg's school have a crush on him, and a good number of boys worship him.

Uncle Charlie

  • Adaptation Name Change: In the webcomic, he was named Freddie.
  • 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).
