Fission Metroids are Phazon-mutated Metroids with the ability to split into two forms. Like all Metroids, they are energy-based lifeforms with a translucent upper body. They have claw-like spikes that protrude from the lower halves of their bodies which they use to latch onto prey, which are probably their equivalent of normal Metroid mandibles. When a Fission Metroid splits into two forms, it endows the new Metroids with invulnerability to most weaponry. However, the effect is unstable, so during the split the Fission Metroid remains vulnerable to one particular weapon fire. The vulnerability is likely random due to the chaotic nature of Phazon mutation. They also explode if they drain too much energy.
In the Phazon Core of the Impact Crater, there are endless amounts of Fission Metroids that rise up through Red Phazon. They also appear in rooms of the third level in the Phazon Mines after killing the Omega Pirate in the PAL version of Metroid Prime, as well as New Play Control! Metroid Prime and Metroid Prime Trilogy in a weaker form. These Fission Metroids will die if they touch one of the Phazon growths in the room, get hit by Auto Defense Turret fire or reach a certain point in front of the Red Door leading to the Processing Center Access room. They also perish after a few shots from Samus, before they can even split. No other Fission Metroids in the game are so weak. The Fission Metroids' differences in strength in both mentioned areas may be attributed to the different types of Phazon located in each. They can also be found in Fungal Hall A and Quarantine Access B.
When Samus Aran battles Metroid Prime's Core form in the Metroid Prime Lair, Fission Metroids will sometimes spawn from the pools of Phazon it creates. There are two ways to kill a Fission Metroid without causing them to split: Power Bombs and the Phazon Beam. Fission Metroids, along with the mentioned core form of Metroid Prime, are the first of their species in the Metroid series to have become invulnerable to cold. Years later, the Galactic Federation would successfully reproduce this invulnerability to the Metroids located on the BOTTLE SHIP.
Fission Metroids initially start out with a mostly transparent white body with aqua tinted nuclei. When enough damage is taken, they split into two of the four types:
- Yellow Power Metroid: Vulnerable to the Power Beam.
- Purple Wave Metroid: Vulnerable to the Wave Beam.
- White Ice Metroid: Vulnerable to the Ice Beam. Similar to their natural form, however their bodies are opaque.
- Red Plasma Metroid: Vulnerable to the Plasma Beam.

Morphology: Fission Metroid
Metroid with the ability to split into two forms.
The Fission Metroid is a mutant, capable of splitting in two. This split endows the new creatures with invulnerability to most weaponry. This effect is unstable, resulting in weakness to a type of weapon fire. The vulnerability appears to be random, due to the chaotic nature of Phazon mutation.
- The images used for the Fission Metroid on Metroid.com are that of a Hunter Metroid.
- A possible explanation for why Fission Metroids split is that Phazon produces Beta-Rays.
- Fission Metroids seems to be hive creatures as they are spawned in the Impact Crater from bubbling portions of Red Phazon.
