Zero Buster

General description
The Z-Buster is Zero's weapon in Megaman X, Megaman X2, and Megaman X3. He actually gains the Z-Saber in Megaman X2, but the Z-Buster remains his primary weapon until Megaman X4. Also, note that the Z-Buster seems to be much more powerful that X's X-Buster, as it sufficiently damaged Vile's ride armor (even though it was only half charged) while the X-Buster could not even visibly scratch it.

Appearance
The Z-Buster creates large, light green energy bolts that travel across the screen, as with any typical buster weapon.
