Super Metroid - Plot

Plot

Chronologically, Super Metroid takes place seventh in the Metroid universe and immediately after the events of Metroid II: Return of Samus, and begins with a narrative by bounty hunter Samus Aran. Samus describes how a Metroid larva hatched from an egg and immediately imprinted upon her, believing her to be its mother. She brought the larva to Ceres Space Colony, where scientists learned that they could harness its power. Just after she left the colony, she received a distress call and returned to find the scientists dead and the larva stolen. The game begins as she follows the leader of the Space Pirates, Ridley, to the planet Zebes, where she searches for the stolen larva in a network of caves.

Along the way, Samus defeats four of the Space Pirate bosses, including Ridley, and arrives in Tourian, the heart of the Space Pirate base. There, she encounters the Metroid larva, which has now grown to an enormous size. It attacks Samus and nearly drains all of her energy before it realizes who she is, and then departs. Samus recharges her energy and confronts Mother Brain, the biomechanical creature that controls the base's systems. Mother Brain nearly kills Samus, but is then attacked by the Metroid larva, which drains it of its energy and transfers it back to Samus. Mother Brain recovers and destroys the Metroid in retaliation, but is in turn destroyed by Samus with an extremely powerful weapon created from the energy given to her by the Metroid. Afterward, a planetwide self-destruct sequence begins, which Samus narrowly escapes.
