Gregory "Greg" Heffley is the main protagonist of the Diary of a Wimpy Kid series; He is lazy, underweight and not to bright. His behaviour is depicted as selfish, rude, idiotic, absurd and unintelligent. He only dreams about being a muscleman and a rich guy, in which none will come true if he continues his low-acting behaviour. At school, he is always seen slacking off intentionally and at home, he spends more time playing his video games than doing his studies.
Greg was born as the second youngest child of the Heffley family. He was raised by Frank and Susan Heffley
