X-Buster

The X-Buster is X 's arm cannon.

Abilities
This arm cannon is very similar to that of Zero, the Z-Buster. The only difference is that the X-Buster has a four-level charged shot instead of the Z-Buster's five-level charged shot. Like the A-Busters and Z-Buster, the X-Buster is able to equip boss weapons to it.
