Arachnus are armadillo-like creatures found on SR388. They appear on SR388 in Metroid II: Return of Samus and appear in a mimicked form in Metroid Fusion. Arachnus appear much less often than most other creatures on SR388. An X Parasite is assumed to have mimicked an Arachnus aboard the B.S.L Research Station. They are capable of attacking by with fireballs and they can also ram their targets.

Appearances

Metroid II: Return of Samus

A less menacing Arachnus

In Metroid II, Samus battles an Arachnus on SR388 that was previously mimicking an Item Sphere on a Chozo Statue. After Samus shoots the Sphere, it starts bouncing around and attempts to hit her. On occasion, it will stop to shoot a fireball. Samus can only damage it by dropping Morph Ball Bombs directly into its path, as any other attacks it will simply dodge. Once she defeats it, Samus acquires the Spring Ball.

Arachnus-X attacking Samus

In Fusion, Samus battles an X mimic of 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 with the Morph Ball upon absorbing its Core-X

Trivia

• Arachnus-X was seen in the first trailer for Metroid Fusion, and was amongst the first enemies to be revealed from the game pre-release.
• 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.
• The Arachnus boss in both games rewards Samus with a Morph Ball-related upgrade: the Spring Ball in Metroid II, and theMorph Ball in Fusion.
