All health X loses turns red, meaning he can be switched out and recover all of his health.

The only difference being that Head Part I has only offensive capabilities while the Head Part of the First Armor can prevent X from taking damage from objects falling onto him using the helmet. This effect is similar to the helmet part of the First Armor, because both parts give the ability to destroy things above X. It can damage enemies, but disappears while X descends. Helmet Parts I: While jumping, a blue field surrounds X.It can only be used when the Neutral Armor is equipped with all four I-Parts. The Icarus Armor ( イカロスアーマー, Icarus Armor ) is an armor for X found in Mega Man X8.
