Becky Thatcher remains firmly rooted in Mark Twain's original 1876 novel *The Adventures of Tom Sawyer*. Her character extends through literary spin-offs and analyses, including expanded universe novels like *Becky: The Life and Loves of Becky Thatcher* and *The Actual & Truthful Adventures of Becky Thatcher*. While an upcoming project titled *The Science Adventures of Tom & Huck* (2025) is noted, no anime adaptations—including seasons, movies, OVAs, or spin-offs—featuring Becky Thatcher exist.
