Arachnus-X

Samus battles an X mimic on an Arachnus on the Main Deck of the B.S.L research station. This Arachnus, due to the nature of the X, is much more menacing and aggressive than the one seen on SR388's surface. Most of its abilities are similar to the one Samus fought on SR388, but the X mimic has a variety of other abilities. From its claws, it can unleash a large wave of energy, and its fireballs detonate on the ground, creating a wave of flame in its wake. Samus can defeat it by firing at its chest.

Samus is rewarded the Morph Ball upon absorbing its Core-X

Trivia

• In the official soundtrack of Metroid Fusion, 'Arachnus-X's battle theme is referred to as VS. Mulcalah. It is unknown why the name "Mulcalah" is used in this instance when all other media refers to the creature as "Arachnus-X".
• A remix of Arachnus-X's theme is used in Metroid Prime 3: Corruption during the boss battle with the Berserker Lord. Both bosses are the first in their respective games.
