Tear Jerker / Dissidia Final Fantasy: Opera Omnia

• Pretty much anything with Krile and Galuf, given that he is Doomed by Canon.
  • In the third scene of her recruitment chapter, she stops him and begs him not to leave her behind again, because she doesn't know what she'd do without him. He responds that he'll always be with her and the rest of the party... until the very end. Anyone who's played Final Fantasy V knows that she's going to learn the answer to that question, very painfully.
  • The "Grandpa" cutscene in Relm's event. Seeing Krile and Galuf happily spending time together makes Relm miss Strago, and Krile says that she hopes they'll be able to meet again soon, blissfully unaware that she will lose her own over the course of her game's events.
  • With the revelations in the Interlude chapter, it's possible that Krile deliberately traveled back in time to a point before Galuf died.
  • Exdeath creates an illusory forest that is strongly implied to be an Expy of Moore—the site of his "birth," and where he killed Galuf. Krile later says that it was scary, and she didn't like fighting there.
• King and Firion assume that Wakka and Tidus have to be from a carefree, peaceful world because they're both professional athletes who love talking about the game they play. There's an awkward silence before Yuna and Wakka explain that blitzball is the only thing that keeps Spira's population from complete misery.
• After Jecht refuses to join the party in Chapter 11, Wakka rushes after him alone and nearly begs him to join them - all so Tidus can have his father, since Wakka never had his own. Similarly, Lilisette expresses sadness about not meeting her own father, telling Tidus to cherish the time he has with his.
• In Act 2, Chapter 1: The sad Irony in the conversation between Yuna, whose job it is to Send the dead, and four characters who die in their respective games (Galuf, Aerith, Papalymo, and Serah), where they talk about the effect the dead leave behind on the memories of the living. Ace, overhearing this, is really struck by the severe Culture Clash between his world and all of theirs, where the crystal prevents them from remembering anyone who died.
• In the same chapter, when the Dark Manikins offer Hope the opportunity to side with Caius and change history so he doesn't lose his mother, even taunting him about it, he angrily tells them not to mention her, and he has to continue living without her.
• Act 2 Chapter 2 focuses a lot on the complicated relationship between Cecil and his brother Golbez, with the latter showing his The Atoner Death Seeker tendencies. Ramza and Zidane are included in one such scene between them, who both have similar relationships with their own brothers, but the Tear Jerker part comes when Vaan tries so hard to get Cecil and Golbez to reconcile, because while their relationship may be complicated they at least have their brothers, while Vaan's had passed away.
• The death of Vivi? the dark manikin in Act 2, Chapter 3 after Taking the Bullet for his original self. Kuja had persuaded him to be The Mole by promising him a heart, but with the party, Vivi? learned about hearts and life from them, and vanishes into light.
  Firion: To think he was hiding so much brilliance in that little body.
• Vivi expresses his sorrow that he didn't get to know the manikin for longer, not just because he'd considered the dark manikin a little brother, but because the new world is the only place he can meet other "artificial" people like himself.
• Whenever party members such as Barret or Sazh talk about their children around Cyan, since the poor samurai lost his entire family (and kingdom) due to Kefka poisoning the water supply.
  • During Prompto's event he attempts to describe how a camera works to the more primitive party members as something akin to painting a portrait but instantaneously. Cyan unfortunately doesn't understand a camera can only takes pictures of things that are right in front of it, and requests Prompto to 'paint a portrait' on his camera of his dead wife and child so he can have their images with him.
• When Gilgamesh reunites with the FFV party, he seems overly concerned about Galuf's well-being and openly weeps after talking to him at one point, confusing the rest of the party and indicating that he knows full well what Galuf's fate will be when he returns home.
• Once the party reaches the Floating Continent in Act 2, Chapter 5, they find a pile of lifeless dark manikins. Several of them are ones they had spoken to and received brilliance from in previous chapters, like Lightning, Yuna, and the Warrior of Light himself. Locke immediately tells Krile to leave because someone her age shouldn't have to see it, while Celes compares it to something from a war.
• The encounter with the dark manikins of Terra and Celes crosses between this and Nightmare Fuel. Kefka's torture of them by forcing them to "birth" a new Blackened Will with their magic has broken them so utterly that they can only babble his philosophy of destruction and despair, interspersed with repetitive bouts of "sorry, sorry, sorry."
• In Machina's event, he witnesses a scene where a few of his classmates are discussing future plans of going to other worlds to see the Gold Saucer or play blitzball after the fighting is over. Machina is saddened because he's the only one who knows they won't survive to get that future, and he can't tell them that. For extra tearjerker points, the other two people involved in that conversation are Aerith and Tidus, who are both prone to doing the same thing in their own games. When the others spot Machina watching them, they go over and ask what he wants to do. His answer?
  Machina: I'd like to go to school with Class Zero again.
• When the cast of FFV encounter their Dak Manikins, Lenna and Faris are sad but accept their painful memories calmly. Krile, however, is visibly shocked when she receives the memories from her manikin. Even though her dialogue in battle implied her suspicions about what Materia thought would be too painful for her to bear, actually having her grandfather's death returned to her clearly knocks her back.
• When the other Type-0 cast regain their memories, most are initially reluctant to accept it. Cinque is more devastated and begins to cry, just like how she did in her home game during the ending. Yuffie and Cater eventually joins in her crying as well, Yuffie relating to them greatly and Cater taking that from seeing both of them cry.
  • Somewhat related; Due to how the Type-0 setting works, typically people don't have much of a chance to linger on the death of an ally due to losing their memories of them. In the World of Respite, however, those memories and the pain associated with them should someone die are here to stay, and Ace finds that out rather harshly after being forced to confront the loss of a Chocobo that had been mortally injured by monsters.
• Freya's Culture Shock and Tidus' Innocently Insensitive remarks about the world of Orience gets expounded on and comes to a head in Act 2, Chapter 9. Machina, Cater, and Cinque go into more detail about how if someone dies they might be able to find traces of an ally in terms of what they've left behind but they can never remember an enemy - and Cinque says this is what allows them to keep fighting against their enemies. Tidus actually has an outburst about this and how they can possibly live that way, which makes Cater give an angry retort about how he doesn't understand what their world is like and has no right to judge them for it, and hates the fact that they're viewed as "cold-blooded animals" because of it. Freya tries to keep the peace but agrees with Tidus while Cinque says all they can do is try their best. Ace eventually says that because of their different worlds the two sides will never be able to understand each other, so everyone agrees to disagree just so they stop fighting.
• Penelo says that she wishes she and Vaan could see their families again both so they could know she and Vaan are okay and to say goodbye to them properly.
• Act 3, Chapter 2:
  • Locke breaks his promise to Celes and leaves her behind, fixated on finding his "treasure." Thanks to their missing memories, he and Celes aren't sure how their adventure ended and where their relationship stands, or if Locke ever found the Phoenix magicite back in his world. Celes struggles with her own doubts throughout the whole chapter because of this.
  • Mog (the FFVI one) is summoned to this world and the first friend he sees is Locke, who reiterates that he's just looking for his lost treasure and left the others behind. Mog gives him a What the Hell, Hero? and says that Locke shouldn't have abandoned the people he cares about because he'll never know if something bad will happen to them. Locke tries to say Celes can take care of herself, but Mog retorts that his girlfriend Molulu could, too, and he still lost her - confirming that Mog truly did end up The Last of His Kind in the World of Ruin. Afterward, Locke leaves Mog behind, too, leaving the poor moogle with abandonment issues. Thankfully, by the end of the chapter he meets Fran and Penelo, who take him in.
• Zanarkand is summoned in Act 3, Chapter 4—specifically, Zanarkand as Auron and Jecht knew it. Both try to take the blame for its existence as the place where Jecht and Braska lost their lives. Auron later admits to Krile that even after ten years and his journey with Jecht and Braska's children, he hasn't gotten over the pain of those events like he thought he had.
• Zack's BT theme is the absolutely heartbreaking "The Price Of Freedom", and the finisher itself is a reenactment of his death scene.
• Braska is a recruitable character in Act 3, Chapter 8, and crossing over into a heartwarming moment is his heartrending reunion with his daughter Yuna, whom he never got to see grow up due to his death defeating Sin.
• Ramza and Agrias haven't appeared at all in Act 3's story. This is because Act 3, Chapter 10 reveals Ramza lost his Compass of Light, so he and Agrias are lost and literally have no idea where their other allies are, and vice versa. That's gotta hurt.
