Skull Barrier
Mega Man using Skull Barrier.

Skull Barrier (スカルバリヤー Sukaru Bariyā?) 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. It is also Dive Man's weakness and Bright Man's semi-weakness, although the latter is much harder to avoid and so close-up weapons are not recommended.  Unlike Leaf Shield, the barrier cannot be thrown.
