Miteralis is a sentient, gaseous virus mentioned in Metroid Prime.
Classified as a Global Exterminator Virus, this deadly pathogen contaminated the atmosphere of the planet Bilium, leading to its eventual quarantine. Its classification as a Global Exterminator may suggest that it was bio-engineered for use as a weapon of mass destruction, or may simply refer to its catastrophic effects.
Symptoms of this disease, and whether or not it exists elsewhere, are unknown.
