Multiple endings

Some games in the Final Fantasy series have multiple or secret endings, the game's ending depending on the player's actions taken during the game.

Final Fantasy V
The ending sequence depends on who is left alive at the end of the final battle. If everyone is left alive, the Warriors of Light return to their lives in their new world, and one of the survivors sends a letter to Mid Previa about what has been going on since the final battle. If everybody survives, the sender of the letter will be Krile. The Warriors of Light meet up at the Great Forest of Moore and decide to embark on another adventure to keep on protecting the crystals of the world.

If, however, one or more characters are Knocked Out at the end of the final battle, they won't be able to leave The Void and are left behind. The ending progresses as normal but the other characters are mourning for their lost comrade(s) and wonder if they were really swallowed into the Void. When the remaining Light Warriors gather at the Great Tree, the Warriors of Dawn appear and bring back any lost party members, saying it's not their time yet to join them, and the four are once again reunited.

Final Fantasy VI
The ending sequence depends on who the player has recruited back into the party by the time they fight the final boss. Celes, Edgar and Setzer are the only mandatory members for the final battle, and Terra will appear after the battle to take part in the ending, regardless of whether she was recruited into the party or not. The more party members the player has, the more ending sequences they get and the content of the ending sequences varies slightly depending who is included.

Dirge of Cerberus -Final Fantasy VII-
The player can unlock the secret ending that shows Genesis Rhapsodos (played by Gackt) waking up in an underground cave, if they collect all G Reports during the game.

Final Fantasy IX
The player can unlock an extra scene in the ending by having the Hammer in the inventory during the ending sequences. The Hammer can be obtained as the final prize from Queen Stella during the Stellazzio coins sidequest. The extra scene shows an additional part of the "I Want to Be Your Canary" play.

Final Fantasy X-2
Final Fantasy X-2 has a few different endings. If the player loses the final battle, Vegnagun will fire its cannon and destroy all of Spira. Defeating the final boss ends the game with Yuna, Rikku, and Paine flying away on the Celsius while Nooj, Gippal, and Baralai hold a speech at the Luca theater about Spira's future.

If, after getting the "Chapter 5 Complete" message, the player presses button ( in the Japanese version) Tidus will whistle at Yuna while she is crossing the Farplane Glen. If the player missed either talking to Maechen in Chateau Leblanc in Chapter 3 or did not trigger Tidus's whistle at the Farplane when Yuna fell in at the end of Chapter 3, the player gets a scene where Tidus's spirit embraces Yuna, Yuna says that she loves him, and that he will always be a part of her. Tidus's spirit then disperses into pyreflies and disappears.

If the player talked to Maechen in Chateau Leblanc in Chapter 3, got Tidus to whistle four times in the Farplane at the end of Chapter 3, pressing after the "Chapter 5 Complete" message triggers Tidus' whistle, and Bahamut's fayth appears in the glen asking Yuna if she wants to see Tidus again.

If answered positively, Tidus will return at the end of the game and reunite with Yuna. If the player answers negatively to the fayth's question, Yuna says Tidus is already with her and walks away from the glen. The ending plays as normal, and Tidus does not return, but the player gets an extra scene after the credits where two monkeys sit in the sunset in Zanarkand.

If the player achieves 100% completion, and Yuna tells the fayth she wants to see Tidus again, there is an extra secret ending where Tidus and Yuna travel to Zanarkand together with the reassurance that this time, he won't disappear.

Final Fantasy XII: Revenant Wings
If the player completes all missions and defeats the final boss at level 99, they get a secret ending after the credits where Vaan and Penelo run away from Rabanastre together and briefly kiss, suggesting a romantic connection between the two.

Final Fantasy XIII-2
Final Fantasy XIII-2 features multiple endings: Final Fantasy XIII-2's normal ending features Serah dying from seeing the future. Noel and Hope along with a reborn Cocoon are sucked into Valhalla by chaos. A crystallized Lightning sits on Etro's throne with a screen reading, "To Be Continued."

There are eight paradox endings, scenes which can be viewed by making certain choices at different stages of the game. They do not change the overall structure of the plot, being only hidden "goodies."

Obtaining all fragments and paradox endings unlocks a secret 'ending' scene, with Caius saying that he will create a world without a goddess. The secret ending is in the Void Beyond with Caius is sitting on the throne. He steps down and says that Serah and Noel have followed his plan and released him and Yeul from their burdens. Now Chaos shall rule.

Witnessing all possible endings earns the player the "Anomalous" achievement/trophy.

In the "Requiem of the Goddess" downloadable episode the player can get an extra scene of Lightning waking up from crystal stasis hundreds of years in the future if they beat Caius with a five star battle rating.

Final Fantasy Type-0
Hajime Tabata, the director of Final Fantasy Type-0, has stated in an interview that there is a secret ending in the game but he hasn't revealed how it will be unlocked. The ending depends on if Class Zero's twelve members choose to become l'Cie or not. If they do, they inevitably lose against an onslaught of enemies and the world is destroyed and remade.

The default ending, if the Class Zero do not become l'Cie and the player wins the final boss battle, shows the last moments of the members of Class Zero, who slowly die in their classroom at the Peristylium from absorbing Judge Cid's phantoma. Cinque loudly cries as she is afraid of death, however, Queen and the others console the girl. Their final moments they talk about how they would have liked to have studied other things other than magic and fighting, like why flowers bloom.

Even though their deaths are inevitable to them, they still talk about what they would have done after the war and what they would be doing in ten years' time. Sometime later, Machina Kunagiri and Rem Tokimiya arrive at the Peristylium just to find their friends dead, lying underneath a tattered banner which consists of the members of Class Zero's red capes knotted together to represent that they will always be together.

Machina and Rem not sharing their allies' fate is explained in secret cutscenes, which depict how Machina became a Byakko l'Cie from Qun'mi Tru'e and his fight with Rem, who became a Suzaku l'Cie in her classmates' place. When Rem dies after being impaled on Machina's rapier, Machina takes her into his embrace and loudly cries before he crystallizes himself around her, creating a bloody red crystal. Though physically trapped, the two aid their friends in spirit during the final battle.

Sometime later, Arecia Al-Rashia approaches their crystal and frees them from their stasis. Machina and Rem then float holding their hands and fly through Arecia. In the game's epilogue, with Oriense's crystals rendered powerless, the two proceed to reunite the people under one banner and begin a new age of self reliance.

In an alternate ending, titled as a what-if scenario, Arecia removes the crystals from Oriense's history and thus creates a new timeline where the Pax Codex is never broken and everyone who died in the war that occurred in the original timeline, Class Zero included, get a second chance in life.

Dissidia Final Fantasy
If the player obtains all the Chaos and Cosmos Reports a secret ending is unlocked where Cosmos is revealed to be alive and well, and discuss the future of World B with Cid of the Lufaine.

Dissidia 012 Final Fantasy
Further explanation is given about the aforementioned scene in the prequel, as Cosmos resigns to remain in the dying world after the events of Dissidia as she wishes Cid the best of luck.
