Hudson Soft later released a slightly re-branded version for the TurboGrafx-CD titled The Dynastic Hero. It features palette-swapped visuals, new insect-themed graphics for main characters (and appropriately, insect's natural predators as bosses), a Red Book audio soundtrack which is completely different from the Wonder Boy original, and anime-style cutscenes at the intro and ending. Shion was renamed Dyna and was modeled after a Hercules Beetle, and the final boss was changed to a giant lizard king. An English-language version was also produced, but both were built off of the Japanese version of Wonder Boy in Monster World so they feature the same difficulty and mechanics as the Japanese version. The English version is one of the least common Turbo Grafx-CD games and sometimes results in high bids on online auctions. This particular version was released on Nintendo's Virtual Console service in Europe on November 30, 2007 and in North America on December 3, 2007.
