The creature's insect-like appearance is a large departure from its prior and well-known larval form. This metamorphosis will only occur if a Larva Metroid is inhabiting planet SR388's environment, or a replica of it. From this stage onward in the species' life cycle, a Metroid can no longer be frozen with the Ice Beam, but can be killed with Missiles regardless. After an unknown period of time, the Alpha Metroid will grow into a Gamma Metroid.
An Alpha Metroid molts from the topside of a Larva Metroid's membrane. The development has granted it new physical features: two blue compound eyes, a central horn, two small tusks, four budding limbs and a plated exoskeleton growing along the dorsal region. The Metroid now resembles an arthropod, and the species' characteristic membrane and red nucleus are now located on its underbelly.
The remake Metroid: Samus Returns has made slight alterations to the Alpha Metroid's appearance. A leech-like mouth has been added between its two compound eyes, the latter which are now red. The tusks and horn now function as an additional set of fangs for the oral cavity.
Absent nuclei Edit
Unlike Larva Metroids which possess four nuclei within their large membranes, Alpha Metroids' have a single nucleus housed in their smaller membranes. It is unknown what becomes of the three other nuclei during the metamorphosis, but due to the fact that a larva leaves nothing but an empty torn membrane when it becomes an Alpha Metroid, it can be logically assumed that the missing nuclei, along with the muscle tissue and fangs of the former, were re-purposed into creating the organism's new body (similar to stem cells). The remaining nucleus is carried within a new membrane for the rest of the Metroid's life cycle.
Coincidentally, Alpha Metroids and all subsequent forms can no longer be frozen but are readily susceptible to concussive weaponry, contrary to Larva Metroids' near invulnerability unless exposed to cold temperatures. This disparity in defensive strength may be determined by the number of nuclei present in their bodies. As for their newfound immunity to the Ice Beam, it is likely a result from the exoskeleton they develop as they grow.
The Alpha Metroid has very basic and straightforward movements, so it does not pose any large threat. Five Missiles on the tender underside will take this creature down. Its only means of attack is ramming, as it lacks the life energy drain of its predecessor, making it one of the weakest stages of a Metroid's natural life cycle.
The creature can perform new attacks in Samus Returns. It will make large swooping motions in an attempt to ram Samus, which can be parried with her Melee Counter and leave it open for damage. The Alpha Metroid can also drop electrical projectiles from its membrane, which Samus can destroy for pickups; these projectiles are seemingly a precursor to the Gamma Metroid's extensive control over electricity.
"This the [sic] shape of a Metroid after its first molting."
- Mochtroids, failed artificial replications of Metroids made by Space Pirates, also possess a single nucleus.
- Metroid: Alpha Type is mentioned in Metroid Prime.
