Here's why:
* Energy Transfer: String launchers store and release energy in a spring, which is then transferred to the beyblade. This provides a powerful launch that is essential for burst-type beyblades, which are designed to break apart during battles.
* Spin Direction: String launchers launch beyblades in a clockwise direction, which is the standard spin direction for burst-type beyblades.
* Compatibility: Burst-type beyblades have a specific launcher port that is compatible with string launchers.
However, string launchers are not ideal for older generations of beyblades, like Metal Fight or Beyblade V-Force:
* Metal Fight: Metal Fight beyblades use a different launch system, and their launchers are designed for a different spin direction and energy transfer.
* Beyblade V-Force: V-Force beyblades have a different launch system that requires a specific launcher type.
In summary, string launchers are a specialized type of launcher designed specifically for burst-type beyblades. They provide the necessary energy transfer and spin direction for this style of battle.
