Raven Beak is a fast and powerful opponent with hard-hitting attacks who can cover the full battle arena very quickly, so going into this one prepare to have your Flash Shift and Space Jump skills tested to the max.

Official Metroid Fusion website "These energy-based creatures have the ability to absorb the life force from any living thing. As the natural predator of X-Parasites, however, the Metroid may now be the key to Samus's survival."

Your best strategy against the Omega Metroid is to attack it as the SA-X did: fire charged Ice Beam shots directly into its belly.

At first you won't be able to injure this huge creature with any weapon in your arsenal, even Ice Missiles won't have any effect. Instead, wait for the Omega Metroid to slash out and strike Samus deliberately, you'll then lose all your health except for 1 unit of energy.
