High Command

From Wikitroid, the Metroid wiki

High Command is the ruling body of the Space Pirates. Although never actually seen in the Metroid games beyond a single Commander, it can be assumed from Space Pirate logs in Metroid Prime and Metroid Prime 2: Echoes that High Command is a force to be reckoned with. Its members are all ex-Commandos. High Command apparently supplies various Space Pirate outposts with troops, supplies, and orders, all of which the troopers seem to respect greatly. In the Manga a Chozo named Grey Voice, Ridley, and Mother Brain are high command with them attempting to get Samus to join them at High Command.
