TAKARA TOMY BEYBLADE BURST GT | B-151 04 ROCK JOKER ZENITH ETERNAL SO
Rock Joker Zenith Eternal So (ロックジョーカー・ゼニス・エターナル・双, Rokku Jōkā Zenisu Etānaru Sō) is a Stamina Type Beyblade released as part of the Burst System as well as the Gatinko Layer System. It was released in Japan on October 19th, 2019 for 1080円 as one of eight possible Beyblades in Random Booster Vol. 17 Tact Longinus.12E.T' So.
Gatinko Chip - Joker
Layer Weight - So
Layer Base - Rock
Forge Disc - Zenith
Zenith, like Magnum, Jerk and Polish, is a Forge Disc made up of a metal core and plastic perimeter making up the gimmick of the Disc. Unlike the aforementioned Discs however, Zenith uses a different metal core with three blades in the shape of "Z"s.
For Zenith's gimmick, the plastic houses rubber sections, meant to increase recoil and increase Attack potential during Disc-to-Layer contact. However, due to most Burst Performance Tips being of similar heights, such contact is rare. Furthermore, if such contact does occur, the rubber is liable to act as brakes, slowing the Zenith combination down. Additionally, because the rubber extends to the underside of the Disc, which when combined with Zenith's rough perimeter, any Life-After-Death potential is nullified.
Despite the non-functioning gimmick, Zenith's metal core is significantly heavier than that of Magnum, Jerk and Polish, with weight comparable to commonly used Core Discs with Frames. Furthermore, the triangular design of the metal synergizes with the Valkyrie series of Layers, significantly increasing their Attack potential without negatively effecting balance.
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 KO 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.
