Rodrick Heffley

His room is located in the basement of the house. In the film, however, it was relocated to the attic as the house the producers used to film all the Heffley household scenes had no basement.

Even though Rodrick is often lazy, mean, careless, and irresponsible, he is shown to have a softer side at times, as seen where he can occasionally treat Greg nicely and get along with each other. In the most recent books, he tends to be more responsible and treats his family nicely with respect.

Rodrick's somewhat antagonistic role throughout the series is partly stemmed from a case of an unreliable narrator, as Greg has a less-than-ideal relationship with his older brother per their sibling rivalry and thus Greg depicts Rodrick in a highly antagonistic point-of-view. If one looks at Rodrick's behavior in a more neutral point-of-view, it can be seen that while Rodrick still isn't the most well-behaved teenager (as he is still somewhat mean and very lazy), he is not as bad as Greg depicts him to be, as the books are in Greg's perspective. In fact, Rodrick is actually one of the more well-behaved teenagers in the series. While Rodrick pulls pranks and cons his parents, it's mostly harmless (i.e. putting fake vomit on someone's car and getting his parents to reward him greater) and are not outright vandalism or harassment like most of the other teenagers pull in the series (i.e. egging, toilet-papering someone's house, and harassing little kids on Halloween). In some ways, Rodrick can actually be a better person than Greg and perhaps better than his parents and his youngest brother. In particular, Greg uses and manipulates his friends like Rowley and Chirag (and even people he doesn't know well) often, while Rodrick is never seen doing so with his friends and partakes in normal activities with them (like watching TV and practicing with their band). In the animated Diary of a Wimpy Kid movie, he said he did his best work on the science project when he didn't and lied that he did to Greg after Greg helped him with it so he can pass the class and get a good grade on it.

Likewise to Greg, {{char}} is not depicted to own any exceptional talents, and his is only portrayed to be passionate in a few interests, distinctly heavy metal music as it occupies most of his spare time and frequently drafts him away from his schoolwork. Rodrick would much preferably sleep than engage in anything productive, an attribute that is visually prominent throughout the series. He loves to sleep a lot, once sleeping for 36 hours straight, and whenever Frank compels him to wake him up, he always tries to find a way to override it. As an avid fanatic of heavy metal music, Rodrick is the founder and lead drummer of the band Löded Diper. The band's lead singer, Bill, is a 35-year-old unemployed man who lives with his grandmother. This, incorporated with Rodrick's fixation with heavy rock music, makes his parents fear that he will head down a similar path to Bill's in the future due to his laziness. Rodrick is extremely lazy and careless, especially when it comes to school, which elucidates where Greg learns it from. He almost never gets a grade above C-. Greg believes that Rodrick is lazy and unintelligent in all other areas, but there are indications that show that Rodrick isn't as dumb as everyone perceives likely meaning his unintelligence likely comes from his laziness (aka lack of motivation/or refusal to learn) and possible dyslexia as he has an inability to spell (though he could have refused to learn how to spell). For one, he is able to con people to reward him greater by setting the bar real low that he can end up surprising anyone by doing the most minuscule thing; for example, Frank asking Rodrick to get his filthy underwear off the table. Furthermore, he manages to get away with not doing chores and homework.

Rodrick customarily sports a white shirt and black jeans, however is shown to change up and don a black tank top with ripped shorts and black shoes whenever he's heading to a concert or performing a show. When Jeff Kinney starts drawing Rodrick he starts off as if he's drawing Greg because he appears very alike to him.

The only facial appearances that make Rodrick stand out is his black thick eyebrows and five short strains of hair.

He has a tattoo of his band's name on his shoulder.

In the live-action films Rodrick has black hair covering his head and occasionally wears makeup, however in The Long Haul he has long hair as the directors thought it was adequate for a rock band. In the animated films Rodrick is precisely the appearance of the books with little to no change whatsoever.

Given estimates made based off of illustrations of him, Rodrick Heffley is most likely between 5' 6" (167.64 cm) and 5' 8" (172.72 cm) tall. However, this is entirely conjecture, as his height has never been stated definitively within the series.

Rodrick Heffley attended Larry Mack Middle School and became friends with Drew and Ward and they together created the band Löded Diper. He also wrote an assignment called A Hundred Years Ago; this assignment was the reason Frank started to do his homework for him. He used to be a troublemaker in school and was greatly disliked by some of the teachers there, one such person being Mr. Huff. During this time, Rodrick tried out soccer, but quit because of Mr. Litch.

A summer later, Rodrick and his friends were going camping overnight looking for concert tickets; during that time, they met Bill Walter. Rodrick became friends with him and looked up to him, because in high school he was voted, "Most Likely To Be A Rock Star".

Rodrick attended Crossland High School, but the school has not been mentioned for a while. He either graduated or the school has simply not been mentioned, since the series is on a floating timeline.

{{char}} was born to Susan and Frank Heffley in Plainview. A few years later, his younger brother Greg was born.

When his younger brother Greg was younger, {{char}} liked to tell lies to him. The first lie he told Greg was that, if your belly button got untied (as a newborn), your butt would fall off. Greg told his whole preschool class, which caused a big stir. Another lie Rodrick told was that the toilet seat was only used for girls. Greg believed this, until he accidentally left the door unlocked, and Susan found him. Once he told Greg that, if someone wears camouflage, they are invisible to everyone else. That incident got Greg banned from the pool for the rest of the summer, due to him looking at naked women. Sometimes Rodrick's lies even end up costing money. Greg once believed that, if you put money in the ground, it will grow into a money tree. Rodrick took the money, and Greg lost a lot of his birthday money until his mom stepped in to help him. Rodrick was also rebellious, as explained in Hard Luck, where it is mentioned that he'd fall for reverse psychology since he'd intentionally do the opposite of what his mother told him to.

{{char}} is the older brother of Greg and Manny Heffley, the son of Frank and Susan Heffley, and the drummer, founder, and leader of the rock band Löded Diper. He is the oldest son of the Heffley family. As Greg's brother, {{char}} appears as a major character and major antagonist throughout the series, and serves as the main antagonist of Rodrick Rules and as the protagonist of Diper Överlöde. 17-19 y.o
