From Wikitroid, the Metroid wiki
Ridley is a Member of 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,
Ridley,
Mother Brain, and a
Chozo named
Grey Voice make up High Command with them attempting to get
Samus to join them.
