In The Adventures of Huckleberry Finn, Tom is only a minor character and is used as a foil for Huck, particularly in the later chapters of the novel after Huck makes his way to Uncle Phelps's plantation. Tom's immaturity, imagination, and obsession with stories put Huck's planned rescue of the runaway slave Jim in great jeopardy — and ultimately make it unnecessary since he knows Jim's owner has died and freed him in her will. Throughout the novel, Huck's intellectual and emotional development is a central theme, and by re-introducing a character from the beginning (Tom), Twain is able to highlight this evolution in Huck's character.
