Key characters

Samus Aran
Samus survives the X infection through a Metroid-based vaccine. Her new Fusion Suit starts with limited abilities, and exploring the research station lets her rebuild the equipment needed to contain the outbreak.

SA-X
The SA-X imitates Samus in her former Power Suit. Its early appearances demand an escape route because its powerful weapons and Ice Beam exceed the weakened hunter’s current defenses.

X Parasite
The X replicate host creatures and their abilities. Samus can absorb ordinary free-floating parasites after treatment, although cold blue X remain dangerous until she obtains the Varia Suit effect.

Arachnus-X
An X imitation of Arachnus confronts Samus near the beginning of the station investigation. Defeating its creature form and exposed Core-X restores the Morph Ball ability needed for narrow routes.
