The Basic System (Japanese: ベーシックシステム, Beeshikku shisutemu) was the first Beyblade System to be introduced that was based on the four and five-layered Beyblades of the Plastic Generation, a term used to describe the Beyblades prior to the advent of the Hard Metal System.
The Basic System was utilized for all three toylines and seasons of the Original Series, consisting of Beyblade 2000, Beyblade: V-Force and Beyblade: G-Revolution. They would soon be succeeded by HMS, the Hard Metal System.
