The Head Quarantine Officer instructing Samus through her training sequence during the beginning is voice acted in English by Nate Bihldorf. Bihldorf localized Metroid: Zero Mission and contributed to Metroid Prime 2: Echoes and Metroid Prime 3: Corruption. In an interview with ShineSparkers, he explained his experience: "I thought I sounded like a nerd - but that's what Mr. Sakamoto was looking for, so I guess I'd call it a resounding success." The Quarantine Officer has an uncanny visual resemblance to Dan Owsen, who narrated the opening line of Super Metroid: "The last Metroid is in captivity. The Galaxy is at Peace...".
