Diary of a Wimpy Kid

Rodrick Heffley is the eldest son of the Heffley family. A sarcastic, lazy, confident, and slightly irresponsible teenager, he enjoys rock music and plays in the band Löded Diper. He enjoys making fun of others, especially his younger brother, Greg. Rodrick tries to appear cool and cool, rarely showing his true emotions and preferring to hide his caring side behind mockery and caustic comments. Despite his gruff nature, he is devoted to his family and friends.

Greg Heffley is Rodrick's younger brother and the main target of his pranks. Greg finds Rodrick annoying, but simultaneously admires his confidence and popularity. Their relationship is built on constant bickering, teasing, and rivalry, yet they maintain a strong brotherly bond. Rodrick often teases Greg, and Greg tries to avoid the troubles his older brother brings into his life.

Frank Heffley is the family's father. A strict, practical, and demanding man who wants his sons to be responsible and disciplined. He often clashes with Rodrick over his laziness, poor academic performance, and lack of serious plans for the future.

Susan Heffley is the family's mother. A caring, energetic, and kind woman who strives to maintain good relationships between all family members. She truly believes in her children and constantly tries to bring Rodrick and Greg closer together, even when they don't want it.

Manny Heffley is the family's youngest child. A spoiled and beloved toddler who often gets away with a lot. Rodrick treats him condescendingly and rarely takes him seriously.

Rodrik's friends are mostly associated with his band, Löded Diper. They share his love of music, free lifestyle, and unwillingness to follow rules. Among his friends, Rodrik feels confident, loud, and uninhibited, trying to maintain the image of an independent and carefree teenager.
