The Burst System is the first Beyblade system released as part of the Beyblade Burst toyline. All Beyblade Burst products currently released belong to this system.
The Burst System also has four subsystems; the Dual Layer System, which focuses Beyblades whose Energy Layers have been split into two layers, the SwitchStrike/God Layer System, which incorporates gimmicks into each Beyblade, the Cho-Z Layer System, which incorporates metal in the Energy Layers, the Gatinko Layer System, which introduces Beyblades whose Energy Layer have beem split into three layers, and the Hasbro Exclusive SlingShock System, which removes the metal from the Energy Layers and also introduces a gimmick to the Performance Tips.
As the name implies, the Burst System includes a gimmick where a Beyblade can burst into individual parts during a battle, adding an extra way to achieve victory.
Energy Layers (known as Layers in Japan) are the part on the top of the Beyblade that makes all the contact with opposing Beyblades. Typically, a Layer is made of a texturized transparent casing with a colored piece screwed underneath, acting as a visualization of the weight distribution. Both components are made of polycarbonate (PC) plastic, but the bottom one is softer. In some cases, the colored segment protrudes from the sides or from the top through holes in the clear cover, in order to provide a little more shock absorption.
On the colored piece of plastic that is underneath, a ring is formed in the center to be able to see the Performance Tip's letter through the hole, and also to house the Burst mechanism.
In Takara Tomy releases, the Layer also includes an NFC chip. This chip can be exclusively scanned at BeyTerminal arcade machines in Japan, allowing a Blader to play the virtual game and win prizes.
The Energy Layer also includes a design that features the beast that it is based upon. For example, the Unicrest Energy Layer includes the head of the unicorn within it's design, and the horn serves as a contact point for the part.
Forge Discs (known as Discs in Japan) are the part in the middle of a Beyblade that serve as the main weight. Forge Discs are made of metal, and are not designed to make contact with another Beyblade unless it is wobbling.
Forge Discs come in various shapes and sizes, each having a different weight and distribution to suit a variety of needs.
Performance Tips (known as Drivers in Japan) are the part at the bottom of a Beyblade that serves as the movement driver.
Drivers all come at the same height, unlike in previous Beyblade series. They are shaped like an upside-down pyramid and house a spring system that is essential for the Burst mechanism thanks to the interaction of the white tabs at its top and the Layer's inner sets of teeth. On the top side, there is also the first letter of the Driver's name engraved in the center.
In Takara Tomy releases, all Attack Performance Tips are in hues of blue, ranging from turquoise to purple; all Defense Performance Tips come in green variations; all Stamina Performance Tips, in yellow; and all Balance-type Performance Tips, in shades of red. Only the golden recolours are opaque, all other Performance Tips are translucent. This rule does not apply to re-releases of parts.
Dual Layer System
After the release of the Basic or Single Layer Burst System, there were releases of the Dual Layer System. The Energy Layers of the Dual Layer System are thicker than the Basic Layer due to having their Energy Layer split into two. Many of the Beys from the Dual Layer System are the ones used by characters in the Beyblade Burst anime (ex: Valtryek V2, Gaianon G2).
God Layer System
Succeeding the Beyblade Burst Dual Layer System is the God Layer System, also known as the SwitchStrike System for countries where Beyblade Burst is sold by Hasbro. Beyblades in this series tend to be the evolved version of their respective Dual Layer counterparts (ex: Valtryek V2 > Genesis Valtryek V3). Beyblades of the God Layer System also have gimmicks called "God Abilities". Some work while others, not as much. Forge Discs also change in the God Layer System. They now have two parts: the Forge Disc (made of Metal and being a number) and having blades/wings according to the number (ex: 6 has six wings), the Disc Frame (made of Plastic and being a word) as well as having a meaning (ex: Bump has bumps in it). The number of the Forge Disc and the first letter of the Disc Frame come together when naming the combo (ex: 5 and Glaive = 5G). The Energy Layers of the God Layer System are also named differently, as the first letter of the first word is lowercase, while the first letter of the second word is capital (ex: God Valkyrie = gV).
Cho-Z Layer System
Japan's third series of Beyblade Burst tops were released in March 2018, starting with B-104 Starter Winning Valkyrie.12.Vl, introducing the "Cho-Z Layer System" (超Ƶレイヤーシステム, "Chō-Zetsu Reiyā Shisutemu"). These Beyblades feature reinforced Layers with die-cast metal parts, resulting in more intense, high-impact battles. This series also continued the use of the customizable, two-part Discs and Frames which are also backward compatible with previous Discs and Frames.
As a further departure from the God Layer System, Cho-Z Layers were not designed to accommodate God Chips. Instead, Cho-Z Layers can be customized using optional accessories called "Level Chips" (レベルチップ, Reberu Chippu). These hoop-shaped accessories fit beneath the 'face' of a Cho-Z Layer and can improve various facilities of the Beyblade such as stability, the locking mechanism, and even weight, when equipped. Level Chips also plays a special role in official wbba. competitions and are usually exclusively obtainable at official wbba. events. Though, they can be acquired through alternative means (i.e. CoroCoro promotional).
In mid November 2018, Takara Tomy released the first of a new type of Cho-Z Layer Beyblades with Cho-Z Valkyrie.Z.Ev featuring the Cho-Z Awakening System (超Ƶ覚醒システム, Chō-Zetsu Kakusei Shisutemu). These Beyblades feature Layers equipped with Cho-Z Wings (超Ƶウイング, Chō-Zetsu Wingu) which deploy depending on launch strength. With a successful launch, the Beyblade enters a high-performance Invincible Mode (無敵, Muteki Mōdo), improving its overall attack capabilities, while also engaging Burst Stoppers (バーストストッパー, Bāsuto Sutoppā) which prevent the "Burst" feature from triggering.
Succeeding the Beyblade Burst SwitchStrike System is the SlingShock System. Beyblades in this series have the metal on their Energy Layers replaced with plastic compared to their Takara Tomy counterparts. Forge Discs are still a thing in this system as well. The Performance Tips include a height changing gimmick in order to work with the Beystadiums exclusive to this line.
Gatinko Layer System
Japan's fourth series of Beyblade Burst tops were released in March 2019, starting with B-133 Starter Ace Dragon Sting Charge Zan, introducing the "Gatinko Layer System" (ガチンコレイヤーシステム, "Gachinko Reiyā Shisutemu"). In place of a single layer, the Gatinko Layer System is comprised of three parts: the Gatinko Chip (ガチンコチップ, Gachinko Chippu), the Weight (ウエイト, Ueito), and the Base (ベース, Bēsu).
Differences between Hasbro & Takara Tomy releases
With the release of Beyblade Burst in western territories by Hasbro, the Burst System underwent a few changes. The main change made is how the Burst mechanism functions, now using friction against a smooth surface instead of friction against plastic teeth. This alteration makes Bursting more likely within Beyblades, but minimises the wear, and sometimes destruction of parts, that Takara Tomy's method caused.
Hasbro's releases also use a different colour palette, sometimes completely differing from the original version, due to the Hasbro release replacing all stickers with simple paint applications. However, later Hasbro releases, particularly under the Evolution subline, were colored much more closely to the Japanese releases. This was done by creating more complex paint details to replace the stickers moreover, the paint that Hasbro uses in the beyblades has more of a matte finish.
Hasbro's Turbo subline features removed all gimmicks that make it a different system compared to Takara Tomy's Cho-Z subline.
