Final boss theme

The final boss theme, also called the final battle theme, is the music that plays for the game's final boss in the Final Fantasy series. Some final boss themes are named after the boss, while others have unique names. Many are simply titled "The Final Battle" or "Battle to the Death."

Final Fantasy
The original releases had no boss theme, and so the battle with Chaos used the normal battle theme. However, in the WonderSwan Color, Origins, Dawn of Souls, Anniversary and mobile remakes, a final boss theme was produced for the final battle, titled "Last Battle."

Final Fantasy II
In the original NES release, the Emperor used the same boss theme as all other bosses, called "Battle Scene 2." In every remake after the Origins release, two boss battle themes were produced for normal bosses, and "Battle Scene 2" was used as the final battle theme.

In the All Sounds of Final Fantasy I & II compilation album, there are four unused tracks for Final Fantasy II. One is labeled "Battle Scene 3" and has been speculated by fans to be what was supposed to play during the final battle, as it has similarities in style to the unused "Dungeon" theme, and to the theme played as the Emperor returns from Hell.

Final Fantasy III
The theme plays during the battle with the Cloud of Darkness. It is known as the first final boss theme in the series, as the original versions of Final Fantasy and Final Fantasy II did not have one. In some remixes of the theme on soundtracks, the theme is titled "Kurayaminokumo," which literally translates into English as "Cloud of Darkness."

Final Fantasy IV
The theme plays during the battle with Zeromus. In the second album with The Black Mages, the theme is titled "Zeromus."

"Zeromus" is reused in Final Fantasy IV: The After Years during the battle with Zeromus's Malice.

Final Fantasy IV: The After Years
Four themes play during the final battle with the Creator. "Planetary Core" is for the first phase of the fight against the Creator's shell, and is also used during the scripted section of the Creator's final form. The theme which plays in the second battle, "Master of Imagination," is also the theme used for the lowest section of the Depths (which is a remix of the Maenad's theme), and acts as the Creator's personal theme.

The third theme, "Straying from Evolution," plays during the Creator's third form and is entirely original. The last plays for the Creator's final form after the scripted section and is called "The Battle for Life." It is a remix of both "Straying from Evolution" and the "Main Theme of FINAL FANTASY IV."

Final Fantasy V
The theme plays during the battle with Neo Exdeath. In the third album by The Black Mages, it is retitled "Neo Exdeath."

Final Fantasy VI
The first final boss theme to have a specific name, "Dancing Mad," is divided into four parts, each of which plays during the battle with one of the tiers of enemies leading up to Kefka, the game's final boss. Remixes of several other themes from throughout the game, including Kefka's own theme, are spliced into the overarching theme.

Kefka's ultimate weapon in the Dissidia series is named after the theme.

Final Fantasy VII
The final boss theme used for the fight with Safer∙Sephiroth‎ has since become the signature theme of Sephiroth himself. It has been remixed many times since its original appearance for Sephiroth's various appearances outside of Final Fantasy VII.

Played during the final battle with Ultimecia, "The Extreme" incorporates "Fithos Lusec Wecos Vinosec" into its opening. The track was rearranged by the Black Mages for their third studio album, The Black Mages III: Darkness and Starlight. It also features the intro to a traditional battle theme after over a minute has passed.

Final Fantasy IX
"The Final Battle" plays during the battle with Necron. In the third album by The Black Mages, it is retitled "Grand Cross."

Final Fantasy X
The final boss is Yu Yevon, whose theme is "Decisive Battle." However, due to it being impossible to lose to Yu Yevon short of creatively killing oneself, Braska's Final Aeon is widely considered the game's true final boss. The song that plays during the battle is "Otherworld," which also plays during the game's opening cinematics.

In A Realm Reborn, "Ultima" plays during the battle against the Ultima Weapon. Technically, Lahabrea is the final boss, but the battle is significantly easier to the point of requiring a deliberate attempt to lose, as such the Ultima Weapon is considered the true final boss.
