Peter Warren Hatcher is a fictional character created by American author Judy Blume.
He first appeared in the children's novel Tales of a Fourth Grade Nothing and in several subsequent Blume stories, most of which focus on his younger brother Fudge.
Because of his parents' frequent overindulgence of Fudge and the occasional blame laid upon Peter for his brother's appalling deportment, he is often left in misery and anger over these factors.
He lives in New York City with his parents, Fudge, and his baby sister, Tamara Roxanne, or more commonly known as Tootsie.
However, in the original illustrations supplied by Roy Doty, his brown hair was combed considerably neater and his appearance was virtually identical to that of Fudge (albeit taller and slimmer).
