Bit-Protector

The Hard Metal System introduced many new concepts compared to the first generation of Beyblades, one of them being the Bit Protector. This holds the parts together, unlike its plastic counterpart, the Bit Chip, which was merely decorative. With the release of the first 5 HMS Beyblades, 2 different stickers for made for the Bit Protector, one of a "bit beast" and one of the emblem. The emblem stickers were the only ones that appeared in later Beyblade toys.
