The History of Dragon Ball Heroes is an unlicensed fan-made trading card set released in 2023, produced outside the official Dragon Ball Heroes framework that Bandai has run for years. Unlicensed sets like this one occupy an unusual place in the hobby: they circulate among enthusiasts who value the artwork and the sense of a community creating its own tribute to a franchise that has shaped generations of fans. Collectors tend to remember such releases for their creative ambition and for the way they reflect how fans keep a beloved series alive between official releases. This card depicts Android 21, a character whose dual-form design and mischievous personality have made her a favorite among fans of the franchise. Collectors seek her card for the way the artwork captures her distinctive look and the playful energy that defines her, making it a memorable entry in an unofficial set that stands apart from mainstream releases.
