Caynox, known as Chaos (カオス, Kaosu) in Japan, is an Energy Layer released as part of the Burst System. It debuted 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. It later debuted in western countries with the release of the Caynox & Wyvron W2 Dual Pack.
Caynox is an Energy Layer designed for Stamina that 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 for Stamina Combinations, the gaps and notches on this Energy Layer's exterior do cause some recoil and provide leverage for opposing Beyblades, especially Attack Combinations. 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 without Bursting in battle, it represents such an immense risk that it is generally not recommended for Top-Tier Stamina/Pure Stamina Combinations. However, the Stamina Combination Chaos Heavy Defense can be used by daring Bladers as a good alternative.
While Chaos 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.
As such, Chaos is recommended for collection purposes only.
Differences in the Hasbro Version
Hasbro's Caynox is virtually unchanged from Takara Tomy's Chaos with the same circular and recoil-enducing shape. While Caynox's Burst Resistance is stronger than the weak teeth of Chaos, it's still below-average. Furthermore, with the release of the SwitchStrike System, especially with the release of Layers with metal such as Spryzen Requiem S3 and Luinor L3, Caynox is too light to be competitive.
As such, Caynox is also recommended for collection purposes only.
