Perfect Phoenix P4 0 Yard-S is a Defense Type Beyblade released by Hasbro as part of the Burst System as well as the SlingShock System. It was released in western countries as a part of the Perfect Phoenix P4 & Myth Evo Dragon D5 Dual Pack for USD$14.99 in the United States.

Energy Layer - Perfect Phoenix P4

Main article: Energy Layer - Perfect Phoenix P4

Hasbro's Perfect Phoenix P4 is a Defense Type Energy Layer that is created by combining the Dread Armor from Dread Phoenix P4 and the Revive Core from Phoenix P4. The alternate combination featuring the other components is referred to as Unperfect Phoenix P4. While sharing the same name as its Takara Tomy counterpart, Hasbro's Perfect Phoenix P4 lacks metal in its design.

Like its predecessors, Perfect Phoenix P4 features a bird in the center and four feathered blades that make up the bird's wings, representing the Energy Layer's namesake; the mythical immortal bird, the Phoenix. The Dread Armor is attached to the rest of the Energy Layer via a locking mechanism, and the Armor can be knocked off during battle. While the loss of the Dread Armor makes the Energy Layer lighter, the smoother perimeter created reduces recoil. Furthermore, the Dread Armor is left in the stadium, interfering with the opponent and impeding Banking Patterns and reducing Stamina. However, this can also interfere with the Perfect Phoenix P4 Combination.

Forge Disc - 0

Main article: Forge Disc - 0

0 is a symmetrical Forge Disc that's elliptical in shape in order to facilitate a Disc Frame. Each side features one protrusion, each wide and smooth enough to almost make the Forge Disc perfectly circular if not for the notches needed to add a Disc Frame and a molded "0" on each side. The protrusions extend further and are thicker than most other Forge Discs which makes 0 one of the heaviest Forge Discs and implies high Outward Weight Distribution (OWD) and Stamina potential. In reality however, more weight is focused towards the center, which creates Centralized Weight Distribution (CWD) that reduces its Stamina to that of 2's. As such, 0 is outclassed by 7 for Stamina Combinations but 0's greater weight makes it ideal for Attack and Defense Combinations. Furthermore, the round shape of 0 creates high Life-After-Death, even without the use of Disc Frames such as Cross. While the weight can increase the risk of Bursts, the weight of most SwitchStrike/God Layers and Cho-Z Layers can compensate.

Performance Tip - Yard-S

Main article: Performance Tip - Yard-S

Yard-S features a free rotating ball tip, akin to its predecessors Orbit and Atomic, surrounded by a wide ring, akin to Defense. As a part of the SlingShock System, Yard-S features a mode change gimmick, allowing it to change between "Battle Ring Mode" and "SlingShock Mode".

In "Battle Ring Mode", the ball tip would increase a Beyblade's Knock-Out Defense by having greater surface area and friction, whilst the wide ring is meant to make contact with the stadium floor when the Beyblade is struck, forcing it back upright and acting as brakes to prevent Knock-Outs. However, in practice the free rotating nature of the ball reduces most of the Knock-Out Resistance given by the surface area of the ball. Furthermore, to facilitate the mode change gimmick, the housing of the ball is raised, making contact with the ring rare. Unlike other ball based Performance Tips, Yard-S does not feature tabs around the tip as their purpose have been taken by the wide base. If launched hard, the greater surface area creates a semi-aggressive movement pattern early in the battle, bringing the Beyblade close to the Tornado Ridge.

While these features may imply that a Yard-S Combination would be easy to Knock-Out, in reality the heavy weight of SwitchStrike Layers, Core Discs and Yard-S' own weight compensates for the rotating ball. Furthermore, the free rotating tip increases Burst Resistance and the taller housing reduces the scrape risk present in Takara Tomy's Yard.

In "SlingShock Mode", the housing is extended so the ball will retract when contact is made on the stadium floor, creating a wide flat tip. While this makes Yard-S highly aggressive, the wide diameter of the tip makes it impossible to hold a Banking Pattern and creates low Stamina. Furthermore, the substantial increase in height makes a Yard-S Combination very easily Destabilized.
