An infectious creature with the powers of Samus Aran, the SA-X from Metroid Fusion was one of the most dangerous opponents Samus was tasked with defeating.

Assume normal (Earth-like) gravity figures for Metroid's inhabited planets.

The thread also covers the threat the X-parasites posed, as well as some of their capabilities given that the SA-X was likely a source for a portion of the X in the station.

Accolades/Accomplishments:

The SA-X was mimicking Samus at her full power, and at the time Samus was no match for it.

The SA-X has Samus’s strongest abilities, is too powerful for Samus at that state to defeat, and threatens the universe.

The Computer states that the Federation thinks the X-parasites have tremendous potential applications, and Samus ponders that the Federation would have no chance at containing them. Also, the Computer mentions how the Federation would take the risk to capture the SA-X, and found it to be too valuable for them to help Samus become strong enough to defeat it. Samus then ponders how the X mimic form, knowledge, and power, as well as how they would spread across the universe and end galactic civilization if they had access to interstellar travel.

“Along the way, collect classic power-ups like the Morph Ball, Screw Attack, and Wave Beam. All these skills will be useful when you encounter the SA-X, an unstoppable X mimicking Samus, which is on the loose and could be just around the corner…”

From Nintendo – Official Site

The SA-X is described as unstoppable.

Durability/Defenses:

The SA-X’s original X form was unable to be harmed by Samus’s missiles after its host was destroyed.

Samus was unable to damage the SA-X when she had the charge beam, super missiles, the speed booster, and bombs, though the computer thought the plasma beam could work. Later, it is revealed that charged plasma beam shots and screw attack hits can deal damage to the SA-X.

Samus gets frozen by the SA-X’s ice beam, and the super missile deals an additional 100 damage to the Fusion Suit. The SA-X’s beam goes through Samus, most likely due to the presence of the plasma beam.

Infectious Capabilities:

“Properties of X-Parasites

X infect other creatures and grow in the nervous systems of these host organisms. Even more worrisome is their ability to control and assume the appearance and behavior of other life-forms through mimesis, a process of infection and replication. The X must somehow be capable of assuming the memories and genetic information of their hosts.”

The X can replicate inside hosts and control or mimic their victims.
