Mega Man X4/Weapons

Playing using X
Where two values are shown, the first one is the damage dealt by an uncharged shot, the second one by a fully charged shot. Exception: the Twin Slasher's third digit is the damage inflicted to Web Spider when cutting the spiderweb.

A plus (+) after the digit means that a single shot can deal damage repeatedly.

The most effective weapon against a boss is highlighted in green. Weapons obtained from the same Maverick are highlighted in red.

Playing using Zero
The table below show the damage inflicted by every Zero's weapon to the Mavericks. Green cells refer to the suggested weapon for each Maverick, red cells refer to weapons obtained from the same Maverick.

About the Z-saber: the first value is the damage inflicted by the first two slashes in a row; the second digit is the damage inflicted by the third slash.

Weapons
Some of the effective weapons can also knock out that boss and interrupt his move, while some other simply deal more damage.

 * Obtained from: Web Spider

 * Can only knockout Mushroom.

Press Special Weapon on the ground. The Z-Saber is electrified and Zero thrusts forward with it. There is slight lag between zero drawing his saber and him thrusting it. However, this can be eliminated by executing Raijingeki in place of the third slash of Zero's standard saber combo.
