List of final bosses

A Final Boss is the last boss in the main quest of the game. After its defeat, it is usually followed by a cutscene as an end to the main story. A common theme among the Final Bosses is that they wish to destroy all existence and return the world to a state of nothingness.

Final Fantasy

However, the real Rydia arrives to call Bahamut to his senses with the Mist Dragon, and the group defeat her.

Unbeknowst to the party the fake Rydia was the first Maenad, and her success prompts the Creator to mass-produce the Maenads in Rydia's image with the power of summoning as she has.

Final Fantasy IV: The After Years
The final boss of Final Fantasy IV: The After Years is the Creator. It occupies the True Moon, which it utilizes as a vessel for interstellar travel.

With the help of the previous generation of the Warriors of Dawn, the current generation destroys Neo Exdeath and recreates the Crystals, resealing the Void.

Final Fantasy VI
The final boss of Final Fantasy VI is Kefka. Using the power of the Warring Triad, Kefka shifted the planet into the World of Ruin, destroying the world as its people knew it and ruling over civilization's ashes as a god.

Deciding that the fate of all life is to be destroyed and hope and love are meaningless diversions from this, Kefka makes it his goal to destroy the planet and the concepts of hope and love themselves, leaving nothing for people to dream about. Having ascended into godhood, he now has the power to do so. The party must impede his plans one final time in the last battle against him. The party defeats Kefka, erasing magic from the world and restoring life to the planet, giving mankind the chance to rebuild what was lost.

Final Fantasy VII
The final boss of Final Fantasy VII is Safer∙Sephiroth. After using the Black Materia to call Meteor to hit the planet, Sephiroth prepares to absorb the Lifestream and become a god. The party descends into the Northern Cave and enters the planet's core where Sephiroth is containing Holy, the only force strong enough to stop Meteor and save the planet. The party kills Sephiroth and he fades into the Lifestream, releasing Holy to emerge from the planet and destroy Meteor with the help of the Lifestream.

There is one last fight between Cloud and Sephiroth directly after this one, but it is scripted and impossible to lose. Thus, for all intents and purposes, Safer∙Sephiroth is the final boss in the game.

Before Crisis -Final Fantasy VII-
The final boss of Before Crisis is Zirconiade. A so-called "Ultimate Summon", Zirconiade's Materia was shattered into pieces some time ago. The three pieces of the Materia were assembled by AVALANCHE's demented scientist, Fuhito, who used them to merge with Zirconiade in order to facilitate his plan to wipe out all life in the world and thus destroy all threats to it.

The Sorceress is defeated and the timestream is restored. However, a weakened Ultimecia appears in the past with Squall as the timestream breaks apart, and Squall witnesses her pass her Sorceress powers onto Edea, marking Edea as Ultimecia's future pawn in her quest for power before turning into dust and ceasing to exist.

Final Fantasy IX
The final boss of Final Fantasy IX is Necron. Distraught over his mortality and unwilling to let life continue without him, Kuja destroys the Crystal that is the source of all life deep within Memoria. Necron takes this as evidence that all life exists only to die, and mankind is ready to accept this truth and return to nothingness, where they will not know the fear and despair that drove Kuja to such extreme lengths.

Zidane states that that's not the case, that life will always continue as long as people have the will to live, and together they can overcome any fear. The party battles Necron and defeats him. However, Necron proclaims he will always live as long as there is life and death.

Final Fantasy X
The final boss of Final Fantasy X is Braska's Final Aeon. Ten years ago, Jecht became the Final Aeon to destroy the monster Sin that terrorized the world, and was transformed into Sin himself when he was possessed by the spirit of Yu Yevon. Entering Sin and making their way to the creature's core, a band led by Jecht's son Tidus destroyed his form as the Final Aeon, forcing Yu Yevon to emerge and seek a new host. With Yu Yevon's destruction, Jecht was finally free to rest in peace, Sin was finally vanquished and Spira freed from the cycle of life and death.

Strictly speaking, after Braska's Final Aeon the party fights Yu Yevon, along with all the Aeons they have earned. However, the party is under permanent Auto-Life status during the battles, making it impossible to lose unless the player sabotages themselves. Thus, Braska's Final Aeon is the true final challenge of the game.

Final Fantasy X-2
