Judge Thatcher’s pretty, yellow-haired daughter. From almost the minute she moves to town, Becky is the “Adored Unknown” who stirs Tom’s lively romantic sensibility. Naïve at first, Becky soon matches Tom as a romantic strategist, and the two go to great lengths to make each other jealous.
Joe Harper - Tom’s “bosom friend” and frequent playmate. Joe is a typical best friend, a convention Twain parodies when he refers to Joe and Tom as “two souls with but a single thought.” Though Joe mostly mirrors Tom, he diverges from Tom’s example when he is the first of the boys to succumb to homesickness on Jackson’s Island. As the novel progresses, Huck begins to assume Joe’s place as Tom’s companion.
