Once exposed to Phazon, a Metroid's lifecycle will be drastically altered, causing it to become a more vicious and efficient predator, which is best seen in Phazon-borne Fission Metroid strain.

Each color is vulnerable only to one beam weapon, Power Beam, Wave Beam, Ice Beam, and Plasma Beam, respectivley.
