Holy Horusood Gravity Xtreme (ホーリーホルスード・グラビティ・エクストリーム, Hōri Horusūdo Gurabiti Ekusutorīmu) is an Attack 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 used by many minor characters in the Beyblade Burst Evolution anime.
Energy Layer - Holy Horusood
Main article: Energy Layer - Holy Horusood
Takara Tomy's Holy Horusood is a Stamina Type Energy Layer that features a bird in the center looking left, shown with the Eye of Horus and four feathered blades that make up the bird's wings, two of which consist of clear plastic and two of which consist of colored plastic that are waved. All meant to represent the Layer's namesake; Horus, the falcon headed Egyptian god.
Like Wild Wyvern, while Holy Horusood seems round at first glance, but upon closer inspection its actually square in shape. Each of the corners of this square-like shape and the waves of the two colored blades create points of recoil that make it unsuitable for Stamina Combinations, while the waved blades do allow for some degree of Destabilization, the feathered design makes them too rough to be suited for such a purpose. This problem is further exacerbated by the fact that it features four teeth, the first short in length, and the last three are medium-short in length. As such, it is prone to losses by Bursts, as the teeth are unable to withstand the recoil the Layer creates.
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 - Xtreme
Main article: Performance Tip - Xtreme
Xtreme features a flat rubber tip with a circular depression in the center, akin to Metal Fight Beyblade's Rubber Flat, that sits at the standard height. Embossed on the top is a stylized "X" for easy differentiation.
Due to the surface area to friction ratio, Xtreme will create a highly aggressive, and if launched with a Banking Shoot, somewhat easily controllable movement pattern. In terms of speed, Xtreme is faster than Accel, Zephyr and Assault but is as fast as or slower than Hold or a worn Variable. Xtreme's high speed allows for strong attacks and its high friction creates less chances of losing the Banking Pattern in battle making it one of the most common choices for Attack Combinations.
However, Xtreme has three major weaknesses. Firstly, the high friction of the rubber means that Xtreme has incredibly low Stamina, furthermore, the light weight of the Burst System compared to previous Systems means that there is less inertia, exacerbating the Stamina issue further. Secondly, the high friction also means that Xtreme resists changes to the Beyblade's spin from contact with the opponent, thus more force is transferred the teeth in Takara Tomy Layers or the slopes in Hasbro Layers, increasing the chances of Self-Bursts. Lastly, Xtreme will wear down with use, decreasing its aggression with little to no improvement to the tip's Stamina, meaning that multiple copies much be purchased in order to replace worn ones.
