8 (エイト, Eito) is a Forge Disc released by Takara Tomy and Hasbro as part of the Burst System as well as the God Layer System and SwitchStrike System. It debuted in Japan with the release of the B-79 Starter Drain Fafnir 8 Nothing on April 29th, 2017. It later debuted in western countries with the release of the SwitchStrike Starter Pack Fafnir F3 8 Nothing.
8, like other even numbered Core Discs, is symmetrical and elliptical in shape in order to facilitate a Disc Frame. Each side features four protrusions, each molded into the shape of an "8". Each of the lower loops of the "8"s features gaps, akin to Knuckle, which takes weight away from the center and creates high Outward Weight Distribution (OWD) and subsequent Flywheel Effect, features theoretically perfect for Stamina. Furthermore, 8 is one of the heaviest Discs in the game, heavier than Heavy, Gravity, 2, 4, and 6 and its use can bolster a Beyblade's Knock-Out Resistance and Attack potential. However, like other heavy discs with high Outward Weight Distribution (OWD) such as Gravity and Ring, the use of 8 severely decreases a Beyblade's Burst Resistance as a trade off.
8 would be a highly versatile Disc as its balance and Outward Weight Distribution (OWD) boosts Stamina and its weight boosts Knock-Out Resistance and Attack potential. As a Core Disc, certain Frames such as Cross can add traits such as Life-After-Death. However, the severe Burst risk posed by the Outward Weight Distribution (OWD) makes it outclassed by 4 and 7 which equal or surpass 8 in terms of Stamina with far greater Burst Resistance.
However, with the release of the Cho-Z Layer System, which is heavy enough to compensate for 8's Burst risk, 8 has found use in Attack Combinations, but is still outclassed by 7.
As such, 8 is not a must have but is instead a welcome addition to a blader's collection.
