Spriggan Requiem 0 Zeta is a popular, customizable Balance-Type Beyblade from the Burst series known for its Dual-Spin (left/right) capability, rubber blades for spin equalization (like Drain Fafnir), and a heavy metal core for weight, making it excellent for stamina and competitive play, especially with its heavy '0' (Zero) Disc and versatile 'Zeta' Driver that switches between Attack, Defense, and Stamina modes.
