Skull Barrier

Skull Barrier (スカルバリヤー) is Skull Man's special weapon. It creates a skull-shaped energy shield around the user, protecting him from attacks. Unlike the Leaf Shield, Mega Man can walk around while the shield is active. In Mega Man 4, it automatically shuts off when it takes a hit, but it can stand against a maximum of three projectiles in Mega Man III, disappearing if it hits an enemy or the projectile is too strong to hold up against.

Capacity
Activating the Skull Barrier in Mega Man 4 and Mega Man III uses 2 weapon energy units. With a full weapon energy gauge, it can be activated 14 times in Mega Man 4 and 10 times in Mega Man III.
