Plot Elements

 * The opening details events a year past, when Dickson, Dunban, and Mumkhar were fighting a Mechon army in Sword Valley, the garguantuan sword of Mechonis.
 * Mumkhar deserts and the Monado paralyzes Dunban's right arm after he uses it to defeat the Mechon.
 * In the present, Shulk studies the Monado in Colony 9, where Dunban, Reyn and Fiora live.
 * Reyn, looking for Shulk, is accidentally possessed by the Monado; the blade accidentally slashes Fiora, but appears to phase right through. While the three fetch ether cylinders, a form of fuel for the Defence Force, a group of Mechon attack Colony 9.
 * Dunban is almost killed when he attempts to use the Monado again, prompting Shulk to try and use it: he wields it with ease and receives visions of the future from it.
 * While the Mechon are driven back, a Mechon with a face, known as Metal Face, proves immune to the Monado and kills Fiora before fleeing.
 * Swearing revenge against Metal Face, Shulk sets out together with Reyn. They meet Sharla from the decimated Colony 6 and work to free it from Mechon occupation, reuniting with Dunban shortly thereafter.
 * Guided by Shulk's vision, the group travels to the High Entia capital of Alcamoth to enter Prison Island, joined by Melia and Riki.
 * Shulk also meets Alvis, who shares Shulk's ability to wield the Monado. Gaining entry, they encounter Zanza, a being who created the Monado and who offers Shulk the ability to destroy the Face Mechon, revealed to be humans inside Mechon mechs.
 * Though Shulk accepts and the Monado is granted the ability to destroy humans, Metal Face attacks with another Faced Mechon called Face Nemesis and seemingly kills Zanza, also killing Melia's father.
 * During the ensuing battle, Face Nemesis is damaged to reveal a partially-mechanical & amnesiac Fiora controlling it.
 * While disheartened by this, Shulk is rallied by his comrades and sets out in pursuit of Metal Face and Fiora.
 * During a peaceful encounter with Fiora, Metal Face attacks them again, revealing itself to be Mumkhar, and holds Fiora hostage in order to blackmail Shulk into surrendering the Monado.
 * Melia disarms Mumkhar, allowing Dunban to fight back, distraught at his former comrade's betrayal.
 * Egil then intervenes, spiriting Fiora away.
 * On the outskirts of Mechon fortress in Sword Valley, the party face off against and defeat Mumkhar.
 * Despite Dunban's anger, Shulk decides to spare Mumkhar.
 * Enraged, Mumkhar tries to attack them, but ignoring Shulk's sudden vision, impales himself on a spire and plummets to his death.
 * At the lowest level of the fortress, the party battle Egil and Fiora, but Egil uses a technology called the Apocrypha Generator to render the Monado useless, knocking the group to the Mechonis' fallen arm between the two titans.
 * Shulk finds Fiora, and discovers that another being was controlling her body.
 * Reuniting with the group, they meet up with Machina Linada and her people, the Machina. She reveals that the Bionis and Mechonis were initially at peace, before the Bionis' god Zanza launched an unprovoked attack, forcing the Mechonis' goddess Meyneth to wound him enough for the High Entia to entrap him.
 * Since the battle at Sword Valley a year before, Egil has been working on his own to convert the life of Bionis into Mechon to render the Monado useless, as it feeds off the ether found in all Homs.
 * Partway through the group's journey to Mechonis, Fiora is taken over by the other presence – Meyneth – who reveals that, after being wounded in the fight with Zanza, she went to sleep before being drawn to Fiora by her love for Shulk.
 * The group destroy the Apocrypha Generator, but Egil reactivates the Mechonis and begins an attack on the Bionis, intent on destroying it as revenge for the decimation it had caused to the Machina thousands of years ago.
 * Despite fighting him, Shulk manages to make him see that they both wish for a return to peace, and declines the open opportunity to kill Egil upon his defeat.
 * As Egil reconciles, Shulk is suddenly shot by Dickson, secretly a disciple of Zanza.
 * The group watch helplessly as Zanza emerges from Shulk's body and reclaims the Monado.
 * It is revealed that Zanza resided inside Shulk's body after he was killed during the expedition to claim the Monado, and Dickson has been preparing Shulk to take control of the Monado and eventually awaken Zanza. Egil and Meyneth attempt to fight him, but they are defeated and Meyneth's Monado is stolen. As the party escapes, Egil attempts to fight once more, but Zanza destroys both him and the Mechonis.
 * After the Mechonis' destruction, Zanza transforms the pure-blooded High Entia into Telethia, who purge Bionis of life.
 * The party is helpless before the Telethia, but a squadron of High Entia intervenes to protect them.
 * However, the High Entia Minister of Research Lorithia is revealed to be Zanza's disciple, and releases ether to transform the High Entia squadron into Telethia.
 * Though the party grieves for Shulk, Shulk awakens thanks to Alvis' help. He manages to defeat a Telethia raid on Colony 6, but Alvis is revealed to be the third disciple of Zanza, though Shulk suspects an ulterior motive. Making their way into Prison Island at the core of the Bionis, they defeat Lorithia and Dickson.
 * The party find themselves in a realm of Zanza, who declares the life of Bionis as simply his food and vessels, and that with both Monados, he intends to recreate the world as he has before, destroying the current world and both everyone and everything in it in the process.
 * Zanza then offers Shulk the chance to become his new disciple. Shulk rejects the offer, and during the ensuing battle produces a third Monado: prompted by Alvis, the spirit of the Monado who betrays Zanza, Shulk uses his Monado to destroy Zanza.
 * Alvis then shows Shulk Zanza's origins:
 * Flashback: Both Zanza, then named Klaus, and Meyneth were originally human scientists from Earth working to create a new universe aboard a space station of which Alvis was the administrative computer. Klaus' obsessive desires caused the experiment to end in disaster, obliterating the universe and causing Zanza and Meyneth to be reborn as gods. After the new universe's creation, Zanza and Meyneth created life in their image, and Zanza created the cycle of Bionis out of fear that he would eventually die as his creations forgot of his existence and sought life beyond Bionis.
 * With Zanza threatening the universe, Alvis asks Shulk, now all powerful, to decide how he will remake the universe.
 * Shulk wishes for a world without gods, where everyone can decide their own fates.
 * In the new universe, the survivors of Bionis and Mechonis build a new settlement and live peacefully together, Fiora is restored to her Homs form, and both she and Shulk optimistically look forward to Alvis' parting promise of endless worlds and races of people beyond their own.
