The First Generation of Bakugan, also known as the Bakugan Legacy Series, or Legacy (Unofficial name), refers to an original era of the franchise, beginning in 2007 (2008 in America). The series featured the four-season run of Bakugan Battle Brawlers, as well as two seasons of a Japan-exclusive "BakuTech" manga and anime spin-off series, and a short-lived Japan-exclusive "Bakugan Armors" series of toys.
The unofficial fan-name for the original series originates from an actual Bakugan term known as Baku-Legacy. This was a term used for old Bakugan from New Vestroia that were re-released in Bakugan: Gundalian Invaders and Bakugan: Mechtanium Surge.
In 2018, the franchise was rebooted, leading to the Generation 2 era.
