The Burst System is first Beyblade system released as part of the Beyblade Burst toyline. All Beyblade Burst products currently released belong to this system.
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.
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.
