Caynox, known as Chaos (カオス, Kaosu) in Japan, is an Energy Layer released as part of the Burst System. It was featured as the prize Energy Layer in BG-01 Random Layer Collection Vol. 1 in December 2015 and was later released in the Triple Booster Set on August 6th, 2016.
Caynox forms a nearly perfect circle, with two "wings" separated by two gaps. Each wing has two larger indentations and one smaller one, and the gaps between the wings each have a head-like design representing its legendary warrior. Its transparent casing is tinted black, and it has white-colored plastic underneath, concentrated around the Energy Layer's perimeter.
Although its circular shape is almost ideal, the gaps and notches on this Energy Layer's exterior do cause some recoil and provide leverage for opposing Beyblades. However, its biggest flaw is the teeth on its underside's center: they are all much shorter than the ring in the middle, which greatly reduces the resistance to rotation between the Performance Tip and the Energy Layer. This results in extremely easy teeth skipping and, ultimately, losses by Bursts. It is such a problem that, even though it is great in Stamina when it does escape un-bursted in a battle, it represents such an immense risk that it is generally not recommended for top-tier combos. However, the Stamina combination Caynox Heavy Defense can be used by daring Bladers as a good alternative.
While Caynox cannot be overlooked due to its remarkable endurance abilities, it poses such a high risk due to the ease with which it can be Burst that it is not fit to be top-tier.
