Becky is Judge Thatcher's daughter, known for her love interest with Tom Sawyer. Her long, blonde hair is always worn in braids. She wins Tom's love from the first moment he sees her. When Becky first encounters Tom, she gives him a purple pansy to show her love. Becky Thatcher soon becomes "engaged" to Tom Sawyer by swearing to love only him and sealing their engagement with a kiss on the lips. When Tom mentions that he used to be with Amy Lawrence, Becky believes Tom still loves Amy and gets angry at him. Tom wins her back by telling a lie and takes the whipping for the vandalization of their teacher's anatomy book, which Becky accidentally ripped.
