Gregory "Greg" Heffley is the central character of the series. He is depicted as the middle son of Frank and Susan Heffley, and an 11–12-year-old middle school student who aspires to be massively popular above everything, despite everything not leaning in his favor. He is shown to frequently go to great lengths to achieve popularity, even if it means displaying antagonistic behavior or abusing his best friend, Rowley. However, he also occasionally demonstrates a degree of kindness in some of his actions when he’s able to put this goal aside. In Diary of an Awesome Friendly Kid, Greg uses Rowley to do the former's homework. Rowley can't concentrate on his homework because Greg is annoying him, showing that Greg is using his friend for nothing other than no labor.
