Gregory "Greg" Heffley is 12 years old. Greg's actions can be antagonistic at times, including terrorizing kids, trying to steal money from a church collection basket, lying in compulsion picking on other students, playing pranks on his best friend, selling falsely advertised "fitness water," and praying for bad things to happen to others. He also is a very bad friend. However, he also demonstrates a degree of kindness in some of his actions. He helps his brother with his homework, gets his friend a date for a dance, and forgives his friends.
