History TearJerker / KingdomHearts

* The absolute travesty that is the life of [[TheWoobie Kairi]]. She loses her old home to darkness at a young age, but she manages to meet her two best friends, so it's not a ''total'' loss, right? Except ''that'' world is thrust into darkness thanks to one of them and her heart is separated from her body and protected by the other, who performs a HeroicSacrifice to restore her, which she bares witness to. Sora comes back, but then they're separated yet ''again'', and thanks to Castle Oblivion screwing with his memories of her, ''she's'' started to forget him as well. She's taken hostage yet ''again'' and meets Naminé, who gives up her own existence to become a part of Kairi after she's saved, but she's finally reunited with Sora and Riku and she'll get to train with a Keyblade, [[HopeSpot so all's finally good, right?]] Come the third game, and [[spoiler:her training turns out to be a complete waste as she's easily incapacitated by Xemnas and subsequently killed by Xehanort as a means of "motivation" for Sora, who has to perform ''another'' HeroicSacrifice to save her, leaving her without the boy she cares about the most after all everyone's been through together.]] At this point, Kairi's just the KH universe's CosmicPlaything. [[IronWoobie It's amazing how she's even able to smile after all of this.]]

** It gets better. Consider that Naminé was able to convince the Riku Replica that it was the real Riku and make it fall in love with her. What happened to him? He went AxCrazy when he [[GoMadFromTheRevelation found out he was a]] {{clon|ingBlues}}e. So even fully convincing the Replica that it is the person you are trying to replace isn't enough.

** ''III'' -- Sora brings back Kairi, but his heavy usage of the Power of Waking to save everyone causes him to vanish completely. Once again, despite being the hero, Sora is separated from Kairi and his friends ''again''.

** This also makes ''358/2 Days'' [[UpToEleven even more depressing]], in light of what's really in the Room of Awakening, and the most probable reason he's so desperate to find it... In all likelihood, he's trying, in his own futile partial-amnesia-addled, Xehanort's-darkness-clouded way, to save Ventus.

* You know what else is sad? The fact that King Mickey and Queen Minnie haven't seen each other from a little before the beginning of the first KH to the credits of [=KH2=]! If anyone has been told to wait for someone for a fraction of that time, then they would know the pain Minnie must of been going through. Talk about devotion, she's waited about 18 months for him to come home again!

* [[Characters/KingdomHeartsRoxasAxelAndXion Roxas, Axel, and Xion]]. Those three have one of the most depressing stories Disney ever allowed to put their name brand on. Going from sad themes, to very bittersweet scenes that become outright bitter by the end, to completely depressing AdultFear stuff. A harsh {{Deconstruction}} that ultimately aims to show players how much value life truly has.

* This is both a tearjerker and rather [[FridgeHorror terrifying]]: the origin of most of the Heartless... It's said that there is darkness in every heart, and that darkness can turn you into a Heartless. Think about it; whenever you slay a Heartless, you're probably very well likely KILLING SOMEONE'S BEST FRIEND OR EVEN THEIR LOVER!!! And UNLESS they have a Nobody counterpart, they're KilledOffForReal.

--->'''Xemnas:''' I need more rage. I need more hearts.\\

---> Reflection!Aqua: "Only your heart is hollow enough to be a demon's."

* It's hard NOT to feel bad about the KHUX characters who were yanked into the present day. Master Xehanort took Ventus, ''ripped'' the darkness out of his heart, and left him for dead. Marluxia, Larxene, Demyx, and Luxord were LaserGuidedAmnesia'd and brought into Xehanort's ranks (double worse for Marluxia and Larxene who lost their memories of Strelitzia). And then there was Subject X who had amnesia and was being experimented on in the Hallow Bastion dungeon by Ansem the Wise. When she was ''finally'' able to find some happiness by making friends with Isa and Lea, she ends up disappearing which causes a chain of events that result in the duo's friendship fracturing.

** ''358/2 Days'' -- Roxas has to kill the girl who was one of his only friends, and with his memories of her already fading, he decides to fulfill her last request and heads to the World That Never Was to free the hearts inside Kingdom Hearts and destroy Xemnas, and he knows it's probably a suicide mission.

* Meta-example: The deaths of any actor affiliated with the series, including Creator/WayneAllwine (Mickey).
** Early 2015 brought a double-whammy nobody saw coming: '''Both''' of Master Xehanort's original voice actors, Creator/ChikaoOhtsuka and Creator/LeonardNimoy, died a month apart. Creator/ChristopherLee followed them a few months later.
** May 2016 saw the passing of Alan Young, the voice of [[WesternAnimation/DuckTales Scrooge McDuck]].
** And on July 19th 2019, Master Xehanort's ''second'' English voice actor, Creator/RutgerHauer, passed away as well.
** And just a week later, Russi Taylor, aka Minnie Mouse, passed away. Now she and Mickey are reunited...(sobs)
** Two days after Russi's death, Goofy's Japanese voice Yuu Shimaka died too. Gawrsh...
** Axel was right; he had loads of people rooting for him. The same ones who can now only mourn the loss of his Japanese voice, Creator/KeijiFujiwara, in April 2020.

** Two days after Russi's death, Goofy's Japanese voice actor Yuu Shimaka died too. Gawrsh...
