|“||At first glance, Metroids are just another species of aerial life-form. However, they have the ability to latch onto other creatures and absorb their life energy. Therefore, the Federation Bureau’s Special Investigation Corps established a Metroid research team, which began studying them.||„|
The Special Investigations Group is a scientific division of the Galactic Federation. They are only mentioned in the introduction of Metroid: Zebes Invasion Order. The group created a research team for the purposes of studying the Metroids, parasitic creatures newly discovered on the planet SR388. They discovered from experiments on a dead Metroid that it could be brought back to life within 24 hours with heavy exposure to Beta-Rays. This Metroid annihilated the team and left their facility in ruin before it was destroyed by the entire 3rd Division of the Federation Space Army.
