History NightmareFuel / LuminousAvengerIX

** Set in a dark and dimly lit room, it's a series of transmission devices used to manipulate Septima, but it's all hooked into a ''[[BodyHorror giant human brain]]''. It's so big because so many life-extending surgeries have kept it alive and caused it to swell up. What makes this particularly awful however, is even way before we see it, Copen refuses to talk about it in front of his friends, and for good reason; this hellish contraption is '''Mytyl''', his little sister, having her brain ripped off and being exploited and tortured by painfully extracting her Septima's influence. Then, Lola hears the sound of her ''crying'' from the resonating robotic parts. She can't even speak, and pre-battle, she makes the message "PLEASE"... "KILL ME" appear on digital screens in the room. The reveal that this is 100 years after the first ''Gunvolt'' implies she has been suffering for DECADES.

* The first stage features an Adept who can revive a Mantis battle tank left in pieces in the slums and turn it into the Zombie Mantis. The scary part is that it sometimes spews piles of junk out, literally its inner guts being emptied. This model was once a Mantis Legion, the weapons deployed to stop Gunvolt from reaching Firmament after Joule was abducted, and they were quite deadly in their prime. Seeing how this was once a cutting edge weapon and even a heavily degraded and hastily rebuilt version still poses a danger to Copen makes you wonder what Sumeragi now uses on higher priority targets, and the first real hint that this is a BadFuture.

* Sumeragi has expanded its reach so far that it is basically a totalitarian state that is driving the powerless Minos to extinction in favor of a dystopian society for Adepts and ''only'' Adepts.
** And if you're an Adept, you are not safe either since you will be subject to living conditions seemingly straight out from ''[[Literature/NineteenEightyFour 1984]]''. You're only slightly less disposable than the Minos despite the protection Sumeragi promises you with.

* The greatest source of nightmare fuel in the game is the encounter with the Butterfly Effect machine. Set in a dark and dimly lit room, it's a series of transmission devices used to manipulate Septima, but it's all hooked into a ''[[BodyHorror giant human brain]]''.

* The UnroboticReveal of Asimov as Demerzel, a being made of pure electronic lightning who has transcended human form and mortality, and also secretly controlled every facet of Sumeragi under the guise as its AI.
** Copen also drops a whopper of a WhamLine to him when he says it's been ''over a hundred years'' since Copen and Asimov first met, and both of them have taken action to augment themselves to persist beyond normal human lifespans, Copen becoming a cyborg despite his aversion to Adepts and Asimov completely abandoning his humanity to become a lightning "god". Copen even thinks that Demerzel's brain has begun to malfunction after all that time and he really is insane, but it's more like he [[WithGreatPowerComesGreatInsanity went mad with power and took to dominating the world, with his transcendence to pure lightning furthering his maniacal machinations]], making him so insane that he ''forgot'' Copen couldn't possibly live for more than a century being human.

* The Lola Tank. It is Sumeragi's answer to Lola's symbol of hope to Minos, and produced en masse. It mimics everything about Lola's abilities right down to CallingYourAttacks. The design is ''not'' meant to be cute: it's a psychological tool to taunt the Minos. Worse, as you attack this enemy, it begins to show progressively more and more damage (unlike other bosses) until it reaches its last health bar, whereupon its mask shatters to reveal five red eyes and activates Darkness Trigger, going berserk by relentlessly shooting energy blasts and revving back and forth. And finally, in a desperate attempt to bind Copen, it uses Anchor Nexus and Lola has to deal the finishing blow.

* The reveal of Asimov as the head of Sumeragi. As a result of killing Gunvolt and Joule, he chose Blade and Mytyl to be the new king and queen he wanted, but the extent of his brutality in doing so makes it very clear that unlike Zonda, Asimov is not creating an adept paradise but a complete dystopia where he is a God, and whatever left of the confident commander of QUILL is now a power-hungry tyrant and the MOST monstrous character in the ''Gunvolt'' series. You could feel sorry for killing every other villain who acted out of [[WellIntentionedExtremist Well-Intentioned Extremism]], had {{Freudian Excuse}}s or are just plain cogs in the machine, but killing this Asimov will put a smile on your face.

* EX Demerzel, the TrueFinalBoss of the game. When Kohaku destroyed the glass container housing his program in sleep mode, it ''didn't'' finish him off. He's miraculously bounced back and then some, turning dark blue and using upgraded versions of all his attacks. However, if you succeed in beating him, you get the satisfaction of personally and permanently killing the bastard who made the world so corrupt.

''Luminous Avenger iX'' is the aftermath following the bad ending of ''VideoGame/AzureStrikerGunvolt'', so it's natural for things to be far worse in this timeline than the good ending.

** If Lola has Darkness Trigger activated in a stage, you'll hear a shrill metal guitar chord and the song "Beyond Probability" overrides any music playing in the background. In this state, Lola tears through enemies with reckless abandon and you can power up EX Weapons. However, Lola succumbs to BloodLust, and if she doesn't constantly have a bounty of enemies to prey on that you can target, her wrath will be redirected upon '''''you.''''' She will drain your life bar until you satiate her or perish.
