Gimmick Specialty Series
Following the initial set of HMS releases covering almost all Manga/Anime-related Beyblades, Takara released the "Gimmick Specialty Series" beginning in mid-summer 2004. Each of the Beyblades in this series have a specific and unique mechanic or gimmick not before seen in HMS, and in some cases, these gimmicks were a first for the Beyblade series on the whole. The end of the Gimmick Specialty Series also marked the end of the HMS Series entirely by 2005.
