Eyezard

Eyezard is the mini-boss in Frost Walrus's stage in Mega Man X4. It is an eye-like probe that transforms itself into various shapes with the ice of the stage. It can only be hit when its red "eye" is exposed. The transformations include a star and a claw which can close and pound the ground sending ice stalactites down to the snowy floor. Its weakness is the Rising Fire / Ryūenjin.

It bear a strong resemblance to the Ice De Voux enemies from Blizzard Buffalo's stage in Mega Man X3. Possibly being a very enhanced/upgraded one. It even loses it's ice shell as it reaches certain health levels, much like the Ice De Voux. It then reforms it's shell if left alone (as a mini boss there's not really any way to avoid this).
