Bryan Little is a character who is mentioned in Diary of a Wimpy Kid. He is the former cartoonist for the school newspaper, and created Wacky Dawg. He was apparently fired from his job as cartoonist because he used the comics for his own personal purposes. He wanted to be the comic winner so he hogged the comics to himself.
However, according to the movie, Bryan couldn't have his comic in the paper for three months because of his having mono.
