History NightmareFuel / KingdomHeartsX

* The Player would have gotten this had they been aware of what Xehanort, whom Player ends up raising in his reincarnation, would have done in his later life. Despite the Player's hopes, Xehanort became his parental figure's own antithesis and worst nightmare.

* The Player would have gotten this had they been aware of what Xehanort, whom Player ends up joining hearts with, would have done in his later life becoming the Player's own antithesis and worst nightmare given how much they are the opposite of Xehanort.
** Adding to this, just the fact Xehanort's heart is connected to Player's is completely horrifying given Xehanort and his many atrocities through his heartless (Ansem Seeker of Darkness), nobody (Xemnas) and his various versions of himself committed. [[MercyKill It’s almost a blessing Sora would eventually defeat him so Player can finally rest knowing Master Xehanort’s plan was thwarted and they no longer have to be in the body of the man who destroyed so many lives and worlds]].

* The Master of Master's sheer ruthlessness in his attempts to eradicate the Darkness from how he planned himself, Luxu and the Foretellers to become vessels for seven of the most powerful Darknesses so they can be destroyed in the future to how he willingly sacrificed the world and countless lives just for a chance to do so. The way he dismisses Luxu's horror at all this is cold even for him showing a severe lack of empathy on his part (though Darkness did cause him to lose many loved ones and comrades which explains said ruthlessness). Granted he already knew it would happen so he couldn't change it if he wanted to anyway and unlike Xehanort in the future, he at least seems to still believe in people enough to try and save them and the future despite ending the world.
* The Player becomes this from the perspective of Ephemer and Skuld and the person playing the game in the finale of UX after they believe they have become possessed by Darkness. They proceed to utterly trouce their friends in battle leaving Skuld unconscious and Ephemer reeling on the ground. Granted Skuld and Ephemer were holding back out of concern for their friend but then so was the Player making it an even fight meaning the Player still utterly trouced them while not using their full power and abilities and there's no reason to think the fight would have ended differently if all three had not been holding back.

** This becomes much worse with the reveal in ''III'' that we have known Luxu the whole time. He's ''Xigbar'' and the apathy that he shows towards the upcoming keyblade war seems to have developed a small degree of hatred for the heroes, mocking them for their ideals. Compare to when we see his past self in Union X wanting to intervene and help the Dandelions despite the Master of Masters' orders. What happened over the years to cause him to pull such a dramatic 180?

** [[FromBadToWorse To make things even worse]], it’s been revealed in a new story update that Lauriam is ''pissed off'' at Brain, demanding to know what happened to his late beloved sister. Brain states that Darkness corrupts others and severs bonds. [[WhamLine And than Ventus walks in, despondently saying that he “erased her”]]. Not killed, but erased, as in ''she no longer exists''. Lauriam then lunges at Ven, absolutely enraged with his Keyblade in hand with full intention to ''kill'' Ventus! Ephemera stops Lauriam in time, when Ven suddenly screams that there’s something wrong with him, [[WhamShot before collapsing to the ground and Darkness emerges in front of the Dandelions, stating “we exist”]].

** Recent events have Ventus getting a painful flashback to a dead Strelitzia. And a later flashback shows that Ven was there when Darkness murdered Strelitzia. But the strangest thing is that he's just...standing there. One possibility is that he's simply trusting the Darkness disguised as Ava, which raises unsettling implications for the UndyingLoyalty the Keyblade wielders have to the Foretellers. Another is that Darkness did ''something'' to Ventus to make him compliant. Either way, the whole situation is just [[HarmfulToMinors one more piece of trauma for the boy]].

** Recent events put ''Ventus'' under some serious suspicion with Strelitzia's murder. While no accusations have been made in story, Ventus was not on the original list for the leaders of the Dandelions. Furthermore, while Ven recalls seeing Ava, Brain points out that Darkness could easily have disguised itself. Not to mention Ventus has a painful flashback to a dead Strelitzia. Even in the best case, Ven may have seen an innocent girl get murdered. In the worst case, this paints a quote from Vanitas in Re:Mind in a new light. Vanitas claimed that he, or at least the darkness that made him, was ''always'' part of Ven and Master Xehanort just drew it out.

** We now know who her murderer was, and no one was prepared for it. ''Ventus'' killed Strelitzia. This paints a quote from Vanitas in Re:Mind in a new light. He claimed that he, or at least the darkness that made him, was ''always'' part of Ven and Master Xehanort just drew it out.

* Mission 546 onwards. Remember the Darklings, aka the Heartless of Keyblade wielders in Daybreak Town? Well, they're COMMON ENEMIES in this mission and appear as such in the next few missions! Sure, they're not as hard as the Boss Darklings in 540, but it still makes you wonder just how many keyblade wielders have fallen to Darkness at this time. The worst bit is that they don't fade into darkness when they run out of health, they just flee.

** Shortly afterwards, Ven and Skuld see glitched-out apparitions of Ava and the Master of Masters in conversation inside the Foretellers' study, and then the ''entire clock tower'' starts glitching out.
