Less sturdy and possessing weaker shielding than the Power Suit, the Fusion Suit takes heavier damage from enemy attacks and is initially unable to protect Samus from extreme cold, to which the Metroid vaccine has left her vulnerable. The visor is also altered, possessing a point in the top-center area, possibly, mimicking the three nuclei inside a Metroid. The helmet gains a Metroid-like appearance, with the sides looking like a standard Metroid's outer talons (or inner talons, if one considers their arrangement). This is also a feature on the Dark Suit, although in this case they resemble the eyes of the Amorbis. The Fusion Suit has small Blades on Samus's free arm reminiscent of Metroid "teeth" or the hooks on the arms of the Chozo it also has three small purple spheres on the back that are similar to a Metroid's internal nuclei. Taking advantage of what was left of her original Power Suit, Samus immediately set out in her new 'Fusion Suit' to investigate X activity on a space station in orbit around SR388.Īs is tradition with the structure of Samus' suits, the Fusion Suit is bulky enough to obscure most details of her figure, even when in such a stripped-down state. This destroyed the X within her but altered her cellular makeup. However, this was not enough to save Samus, and she seemed close to death until the Federation administered Vaccine "Metroid", created from Metroid DNA. The organic parts of the suit had physically bonded with her, and the majority of it had to be surgically removed.

When Samus was attacked and incapacitated by the then-unknown X Parasites, the doctors treating her were unable to take off her Power Suit while she was unconscious. 4.4 Metroid Prime: The Official Nintendo Player's Guide.
