Chest plate



Chiton armor is a form of natural chestplate armor, which creates a thick, ribcage-like covering over the core of an Omega Metroid. This means that unlike Alpha, Gamma or even Zeta Metroids, the Omega Metroid can defend its weak point. This armor is a new ability of the creature in Metroid: Samus Returns, which has expanded the Omega Metroid battles from Metroid II: Return of Samus.

Samus can destroy the chiton armor gradually with Missiles, Super Missiles and Ice Beam shots, and can destroy it instantly with a Power Bomb. When the armor is destroyed, the Omega Metroid recoils back twice, and the exploding armor releases Missile and Super Missile Ammo, and Energy Capsules. After the armor is removed, the Omega will attempt to lunge at Samus, opening itself up to a Melee Counter. followed by a Grab Sequence where Samus can inflict damage to the membrane. After the Grab Sequence is over, the Omega Metroid will regenerate its armor.

It should be noted that the correct term for this armor would be chitin, and not chiton.
