Crystal Eye

Crystal Eye (クリスタルアイ) is Crystal Man's Special Weapon. When equipped by Mega Man, he can shoot a large artificial crystal orb. When it hits a wall, it splits into three smaller orbs that bounce about for a while before disappearing. They disappear after hitting an enemy. Only one Crystal Eye can be on the screen at one time. This includes the smaller orbs, so the player must be careful about their shooting, especially against an opponent that deals high like Napalm Man or one that requires precision to hit (Big Pets). The smaller orbs do the same damage, with the exception of Big Pets, who takes 2 damage instead of 4 from a small orb.

In Mega Man 5, Crystal Eye is effective against Napalm Man, Dark Man 2 and Big Pets.
