Image:SA-X Sprite 2.png The SA-X from Metroid Fusion is believed to have come from the Quarantine Bay on the Main Deck. Because it absorbed Samus' abilities, it used a Power Bomb to breach the protective capsule it was in and the capsules containing other X Parasites. With the Ice Beam and Samus' other abilities, it easily opened the Level 0 hatch guarding the bay and left to go to one of the sectors. This can be evidently seen when entering the Quarantine Bay area where there is a warped wall. The bay is the first mission of Samus'.
