"History of Dragonball Heroes" is an unlicensed fan-produced trading card set from 2023, created by hobbyists who wanted to chronicle the story arcs of the Dragon Ball franchise through a format familiar to card collectors. Unlicensed sets occupy a distinctive corner of the hobby: they are made outside official channels, often with considerable creativity, and they tend to be remembered as artifacts of fan passion rather than as commercial releases. This set is notable for turning the sprawling history of the franchise into a collectible narrative, letting fans hold the moments they grew up with in their hands. Card Mai, number unnumbered in this listing, features the character Mai, drawn from the franchise's storytelling and presented in the set's distinctive fan-made style. Collectors seek cards like this because they capture a specific fan perspective on the franchise, and because the act of assembling a history through cards gives each piece a role in a larger story worth preserving.
