The History of Dragon Ball Heroes set released in 2023 is an unlicensed fan-made release, produced outside the official Dragon Ball Heroes card game from Bandai. Unofficial sets like this one occupy an interesting corner of the hobby, where enthusiasts reimagine familiar characters and moments in the style of officially printed cards. Collectors often remember them for their ambition, their nostalgic pull toward the franchise's long history, and the way they blur the line between fan art and trading card. Because they sit outside official distribution, they are discussed mainly among dedicated fans and communities. Android 21 is one of the most recognizable characters from the Dragon Ball franchise, known for her shifting appearance and her role as a memorable antagonist. This card brings her into the Heroes framing, a choice that appeals to collectors who enjoy seeing her portrayed in a different light. Fans tend to seek out her cards for her distinctive design and the lasting interest she has generated across the series' many fans.
