Performance Tip - Eternal
Main article: Performance Tip - Eternal
Eternal features a sharp tip of a small diameter surrounded by a free-spinning dish made of PolyOxyMethylene (POM) thermoplastic, akin to a combination of Revolve and Bearing. The sharp tip of Eternal provides low friction with the stadium floor, resulting in high Stamina and Burst Defense properties. While the small diameter of the sharp tip may imply easy Destabilization, the wide diameter of the free-spinning ring helps maintain Stability. The wide diameter of the ring also provides Eternal high Precession time which is useful against Opposite-Spin and Mobile Stamina Combinations. However, due to the low friction of POM plastic, Eternal has slightly less Knock-Out Resistance compared to its predecessor Revolve.
In the current metagame, Eternal is best suited for Pure Stamina Combinations due to the use of Atomic, akin to Revolve. While the POM ring may imply higher Precession, akin to Bearing, the lack of a bearing mechanism means that the POM construction has a negligible effect and that Precession is more dependent on how free-spinning the ring is. What does effect the Precession time is the diameter of the Dish; Eternal's dish is much wider than Revolve's, making it outclass Atomic in Precession time and outclass Revolve in most areas.
Eternal is slightly shorter than most other Pre-Cho-Z Performance Tips. In theory, this is meant to prevent the opponent's Layer from striking the Eternal Combination from below and Destabilizing it, thus increasing Defense potential. In practice however, due to the design of the Burst System, this increases the chances of Disc-to-Layer contact and can potentially Burst the Eternal Combination. Though the only minor reduction in height heavily mitigates the effect.
- Air Knight's name is based on "air", the invisible gaseous oxygen and nitrogen compound in the Earth, and "knight", a warrior who served his/her sovereign/monarch/lord as a mounted soldier in armor.
- Air Knight's avatar appears to be similar to Wonder Valtryek/Turbo Valtryek's avatar, but with silver armor, more wing attributes and twin swords.
- To enforce its air motif, the wings on its armor are feather-like while the six wings on its back are insectoid.
