Disc

The Disc, sold under the name Forge Disc in Hasbro's line, forms the middle layer of a Beyblade Burst top and shapes movement pattern, balance, and overall weight. Most Discs are a single die-cast metal piece, though a "Material Fusion" variant blends plastic with metal, and Two-Part Discs add swappable Rings on top of a base disc to change how a build performs. A specialized Rip Fire version strips out the usual socket for Performance Tips and Stoppers in favour of a wide ring built to fit Rip Fire tips, and some Beyblade parts fold a Disc directly into another component rather than keeping it separate. First produced in Japan in 2015 with the launch of Takara Tomy's Beyblade Burst line, the Disc plays the same structural role earlier generations gave to Weight Disks and Fusion Wheels.
