What organization employs Samus as a bounty hunter?

The organization that employs Samus as a bounty hunter is the Galactic Federation. It is the galaxy’s major governing and military authority, and it frequently hires Samus for missions that require skills beyond ordinary Federation forces.

Samus was once a soldier in the Federation. After leaving following a dispute with her commanding officer, Adam Malkovich, she continued working independently as a freelance bounty hunter. The Federation still contracts her for dangerous assignments, including investigating Space Pirate activity, containing biological threats, and responding to crises on remote worlds.

Federation Force is not the organization’s name; it is an elite group of Federation marines and the title of a later Metroid game. The terms “Bounty Hunter Guild” and “Space Federation” are also not the series’ canonical names. Samus’ relationship with the Federation is professional rather than that of a current regular enlisted soldier.
