Kaiser Kerbeus Gravity Revolve (カイザーケルベウス・グラビティ・リボルブ, Kaizā Kerubeusu Gurabiti Riboribu) is a Stamina Type Beyblade that's a part of the Burst System as well as the Dual Layer System. As an anime-exclusive Beyblade, it was never released. It was owned by Ghasem Madal before he obtained Maximus Garuda 8Flow Flugel.
Energy Layer - Kaiser Kerbeus
Main article: Energy Layer - Kaiser Kerbeus
Takara Tomy's Kaiser Kerbeus, like its predecessor Kerbeus, is a round and thin Energy Layer designed for Defense. As such, its design consists of a six-bladed top-layer made of clear plastic; that each have a large gap in between, and a round bottom-layer made of colored plastic that's molded into the shape of chains; with each "link" of the chain-like layer slightly protruding outwards. In the center of the Layer are three dogs heads with flames near each head, representing the Layer's namesake; Kerberos, the three-headed guard dog of the Underworld featured in Greek mythology.
At first glance, the design of Kaiser Kerbeus, while round, appears to imply high recoil. However in reality, due to how thin the Layer is, both the clear and colored plastic layers come into contact with the opponent's Layer at the same time and cover each other's gaps in the process, and as such, is capable of reducing recoil and potential subsequent Stamina loss. Its strong teeth made it excel in Defense Combinations when in certain conditions. However, while this may imply high Defense potential, there are two major weaknesses:
First, when the Kaiser Kerbeus Combination is knocked off balance, only the six-bladed top-layer will come into contact with the opponent. As such, due to the aforementioned large gaps in between each blade, this increases the risk of the Kaiser Kerbeus Combination Bursting. As such, it is critical to pair up Kaiser Kerbeus will a Performance Tip with great Stability.
Finally, the weight distribution of the Layer ends up creating poor Stamina, making Kaiser Kerbeus Combinations liable to being Out-Spun.
Forge Disc - Gravity
Main article: Forge Disc - Gravity
Gravity has a thick, octagonal shape and bears designs that resemble steel plates on each of its eight segments. As with all Forge Discs, it has two tabs that protrude from the top and fit in the slots in the Energy Layer. These tabs are marked with a stylized G to identify the Forge Disc.
Gravity was tied with Heavy for the heaviest Forge Disc in the game, making it a solid choice for adding weight to the Beyblade and increasing its Knock-Out Defense. Compared to the rather compact Heavy, Gravity has a larger diameter and more of its weight packed around its perimeter, giving it arguably what was the best Stamina in the game and increasing the mobility of more aggressive Combinations with the Flywheel Effect. However, it has been outclassed by 7 for Stamina. The high spin momentum provided by Gravity's Outward Weight Distribution (OWD) means that the overall Beyblade will not lose much spin upon collision with an opponent, however that means that the force of the impact will instead be absorbed by the Energy Layer, causing it to skip teeth to cope with the shock.
Performance Tip - Revolve
Main article: Performance Tip - Revolve
Revolve features a sharp tip of a small diameter surrounded by a free spinning ring, akin to the Around Sharp Performance Tip from the Metal Fight Saga. The sharp tip of Revolve 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 Revolve high Precession time which is useful against Opposite-Spin and Mobile Stamina Combinations. Furthermore, when launched at an angle, the free spinning ring of Revolve makes more contact with the stadium floor resulting in decent Knock-Out Resistance, however said Knock-Out Resistance still lags behind that of Orbit and Atomic due to the lower surface area and some Beyblades that are off center are easier to Burst.
In the current metagame, Revolve is best suited for Pure Stamina Combinations due to the release of Atomic. However, Revolve's spring lock is stronger than that of Atomic and Orbit's, allowing it to be a safer choice for Layers with weak teeth such as Deep Chaos.
Due to considerable manufacturing variations, Bladers must be careful when using this Tip. Some variations of Revolve do not spin freely as they should, and the disc becomes very stiff to tilt. Others have the disc pop out after significant usage. For competitive use, the most free spinning one is ideal. The chances of obtaining one, however, are random.
