Yu-Gi-Oh! VRAINS/Nightmare Fuel

Season 1

 * The first episode has one of the Knights of Hanoi destroying people's avatars with his monster. While it's said that their accounts are deleted, it doesn't change the fact that people are running away in terror from the Knights of Hanoi and look to be killed. It also doesn't help that Ignis says getting hurt in Link VRAINS could affect your physical brain, causing mental damage.
 * Yusaku himself is already a walking example of this: he's very unpleasant, is a No-Nonsense Nemesis driven by rage and hatred, and treats Dueling as a means to get Revenge on the Knights of Hanoi. As some viewers noted, Yusaku is what Yuya would've become if he embraces brutality over entertainment. Even his "Reason You Suck" Speech as Playmaker, while simple, really shows how cold-hearted he is, topping the likes of Jack and Reiji in this department:
 * After Yusaku defeated the Knight of Hanoi in a duel, it tried to self-destruct in an attempt to take Yusaku with him, and would have succeeded if Ignis hadn't devoured him and destroyed his avatar then and there. The way Ignis ate the Knight is also pretty unsettling.
 * Somehow, Revolver could sense Yusaku tampering with Ignis, which leads to Yusaku running outside and somehow seeing the cyber world with Revolver coming straight for him on top of a dragon. Thankfully, turning off the power also turned off the signal, making Revolver lose sight of Ignis.
 * Some of Aoi's facial expressions in #6 are rather off-putting...
 * Everything about the last turn of the Aoi/Blue Angel Vs Yusaku/Playmaker duel in #7. After drawing "Dark Angel", the card Specter gave her last episode, Aoi goes berserk with a purple aura and starts dueling in monotone. Then she starts screaming as Yusaku sets up an OTK to save her from Hanoi's influence.


 * Episode 8
 * Yusaku finding Aoi knocked out on the rooftop after he logs out. Fridge Horror ensues when you realize that if Yusaku didn't know she was Blue Angel, she could have been up there for who knows how long.
 * Aoi being effectively brain dead due to the Knights of Hanoi placing a computer virus in her
 * Ema and Akira's trap for Playmaker causes a Barian-esque ring of spikes to apppear around the tower Ema and Playmaker are standing on. It then procedes to either log out or delete the accounts of everyone in Link VRAINS at the time.brain. And she'll never wake up again unless Playmaker beats Revolver in a Duel.
 * Akira torturing Playmaker due to thinking he caused Aoi's condition.
 * And then the Wham Shot of the episode. Revolver can control the Data Storm.
 * Revolver shows his power by reshaping link VRAINS into a volcanic battlefield.
 * 12 has Ignis attack Revolver like a wild animal in order to get his missing data back, going so as to devour Revolver's left arm. Granted, it was only his avatar, but previous episodes have mentioned that sufficient damage to one's avatar can transfer over to their physical body, and Revolver looked to be in pain as he clucthed his wounded arm.
 * We also got to see a better look at ignis in his Monster form, He has eyes resembling those from his old form on his chest. It's a bit creepy
 * 15, Ghost Girl is nearly swallowed up by the Data Storm after following Playmaker in to it, only surviving thanks to Playmaker. A grim reminder that the Data Storm's danger isn't an Informed Flaw, and that Yusaku/Playmaker risks his life every time he performs Storm Access.
 * Yusaku's past with the Hanoi project is chock full of this. Him and 5 other children were abducted and forced to duel AI constantly for survival, being painfully shocked and starved if they lost. Even years later and after therapy to attempt undoing the trauma, Yusaku's entire motivation is getting revenge on the people who committed the atrocity and make sure all the children like him were rescued. For a series that usually places its horror in supernatural elements, the more grounded and realistic child abduction and torture is a much more terrifying event than the series has ever dealt with.
 * It turns out the mastermind of the Hanoi Project died three years after the project was executed.
 * Episode #22 has Dr. Genome, who creates "Another" victims by drawing them into Link VRAINS against their will and them infecting them with a computer virus just like Blue Angel. Even worse, he does this to draw out Playmaker.
 * Episode #27 brings Naoki being kidnapped in real life by a member of the Knights of Hanoi to lure out Playmaker. It's a wonder Yusaku doesn't react worse to it, considering his reason for hunting down the Knights of Hanoi in the first place.
 * As Blue Angel is defeated by Spectre, she lands on the ground head-first. Ouch.
 * Spectre's origins as one of the children kidnapped in the Lost Incident opens up a fair bit of Fridge Horror. How else would the other individuals have been affected by it?
 * At this point, Spectre may as well be the Nightmare Fuel Station Attendant for VRAINS. Not only is he the Second in Command for the Knights of Hanoi and the cause of Aoi's berserker state, he pulls numerous Slasher Smile's that rival the likes of Vector, Sora, and Yuri, and his origins make him an Evil Counterpart to Yusaku. Whereas Yusaku has been consumed with revenge and hates what the project did to him, Spectre became twisted and joined the very cause of the Project, and is grateful for what the project did to him.
 * Speaking of Yuri, Spectre's origins are disturbingly similar to Yuri's, yet it makes Spectre even more terrifying. Both Yuri and Spectre were once gentler as children, before being exposed to a much more negative influencenote, causing them to develop a much more sadistic and twisted personality. Spectre's is more terrifying as whereas Yuri had Z-ARC's influence partially to blame, Spectre has no such influence. The Hanoi Project was that torturous.
 * Playmaker's vehemently pissed off expressions after Akira sacrifices himself are proof that you do not want to fuck with him, lest he decimate you to nothingness in rage. Spectre learns this the hard way.
 * Episode 42, we actually see the dangers of a really intense Data Storm as both Playmaker and Revolver attempt to activate Storm Access and their arms literally get ripped off of their avatar. It was so intense that Playmaker actually falls off. Had Ai not helped him up, he would have been killed from the height he was dueling from.
 * Revolver did the right thing by reporting the Hanoi Project and in turn saving the six kidnapped children who had been tortured and starved for six relentless months. He quickly regretted it not because he was evil, but because his father was imprisoned by SOL Technologies for three years in an attempt to cover up the incident. Revolver didn't get to see him during this time and when Dr. Kogami finally returned home, he was comatose with a computer virus keeping him that way. Even after removing the virus, Revolver couldn't restore his father's consciousness in the real world. Revolver must blame himself for this.

 * Who knows how long the Hanoi Project would have lasted if it had never been reported.

Season 2
gets attacked and traumatized again. While Akira knows that Earth has free will and can only look away in guilt, Queen is indifferent about Earth's protests because he is an AI and SOL Technologies's main source of profit; why should she care? **Even worse is that Aoi and Emma witness the entire thing and are horrified at Earth's treatment and suffering.
 * Ai returns to the Cyberse World in episode #47 after five long years, but instead of the paradise he described in episode #45, there is only a wasteland remaining, the other Ignises are nowhere to be found, and the only survivor shown is Linkuriboh. By the time Ai found him all it could do was hide in the remains of Cyberse.
 * The most horrifying part of this is that Ai himself hid Cyberse away. Neither the Knights of Hanoi or SOL Technologies, two very powerful organizations, could find it even with the five years they had before Yusaku captured Ai, but somehow someone or something managed to find and attack Cyberse and reduce it into a wasteland.
 * Jin gets attacked by an avatar in the real world. The avatar first gets out of a television screen like Sadako. Shoichi tries to stop it, but couldn't even touch it. The avatar then grabs Jin's head and takes his soul by sucking it through its mouth. All Shoichi could do was helplessly watch how his brother It's also quite off putting that Jin doesn't talk and only grunts to his brother Shoichi after making a small recovery. This in turn shows how much the Hanoi Project/Lost Incident affected him.
 * Bohman's Identity Amnesia is a just a tad off-putting, what with how easily he seems to panic and how Haru has to keep watch over him as he duels.
 * It's even scarier that in Episode 50 it was shown that his boss has his memories. After getting Jin's consciousness to him his boss was supposed to give Haru's and his memories back, but instead his boss just claims he never made that promise, that it's all in his head, and resets Bohman's memories. And judging from Haru's emotionless expression suggests that this happens quite often and that he needs to give Bohman new memories AGAIN.
 * Episode 54 revealed that Kengo Dojun/Blood Shephard and his mother are a victim of a car crash caused by the glitch of an AI. The horrifying part is what happened with them afterwards. Kengo's mother spine was damaged beyond repair and crippled her. Kengo's arm was crippled till the point he needed a cybernetic replacement and the accident turned the once cheerful young man into a jaded ruthless man with a deep hatred for AI's.
 * The fact that the AI glitched at all shows that despite how advanced technology has come, it will never fully be perfect and problems would happened or least be found and there is a chance that someone will suffer the price for it be by death or serious injury.
 * In episode 57, Bohman claimed he is the real Yusaku and the current Yusaku was a backup made during the Lost Incident. If this is true, then being trapped in a computer for ten years must have messed him up a lot. If this is false, which is incredibly likely as Bohman's latest memories could be fake and he has yet to regain his confirmed real memories, being made to believe he had gone through such a grueling experience would still be absolutely horrifying.
 * Episode 58 also shows that Bohman saw what the fake did in his body when he finally got rescued. He is forced to watch the fake getting away with his body and smiling at him knowing that he doomed the original to stay in a computer possibly forever.
 * Playmaker doesn't even deny the possibility. He actually says it might be possible that he is a fake, because of the memories he lost and that there is no way to know which one of them is right. While Playmaker won the duel, there still isn't any confirmation about Bohman's claim.
 * Even Ai stated it is possible and Ignises are supposed to know who their partner is which is how Flame found Takeru.
 * While Yusaku's and Ryoken's first meeting may look cute and innocent at first, it's actually pretty horrifying if you think about it. Yusaku just met a boy with similar interests as him and went to play with him, but instead of playing, he got kidnapped instead. Just think about it your child is going to play with someone you don't know or met and hasn't told you anything about it and that it resulted in him suddenly disappearing. His parents must be worried sick that their 6-year-old kid suddenly didn't come home one night. Adult Fear is in full effect here.
 * Ryoken, being eight at that time, most likely did not intentionally lead Yusaku to being kidnapped hence him becoming Yusaku's voice of hope; he probably felt guilty for unknowingly dooming Yusaku to such a horrible fate. Ryoken was most likely just an innocent kid who loved playing Duel Monsters and was happy to make a friend in Yusaku. Ryoken most likely actually just wanted to show Yusaku his deck at his house, become friends with Yusaku, and did not intend anything bad. The fact that something bad did happen must have made Ryoken feel horrible.
 * This also implies that Dr. Kogami is willing to use his son to get the people he needs for him to experiment onnote It involved getting tortured with electrocution and starvation for losing a duel.
 * Soulburner saves Playmaker, but gets caught by Blood Shepherd's trap instead of him. While this is already bad considering how ruthless Blood Shepherd, but what makes this worse is that getting captured in a closed space triggers Soulburner's flashbacks of the Lost Incident/Hanoi Project from it. He sees the A.I. he is dueling against as a big black monster that wants to hurt and attack him.
 * Said big black monster is Despair from the Dark. During the Lost Incident, Takeru was defeated by that monster and was subsequently electrocuted and starved so many times because of it, he developed an intense fear of that card. It highly likely Takeru developed his fear of ghosts because of this card and the relentless torment it inflicted on him. Even after ten years, his sheer terror did not abate one bit seeing as how he reacted so horribly when Ryujiro Mizunuma—his opponent when they dueled in the real world in the past—summoned it.
 * And in episode 62, Blood Shepherd uses this newly-found knowledge against Soulburner in the most drastic extreme possible: Blood Shepherd assembles three copies of the monster via a specific combo, effectively exploiting Soulburner's trauma for all that its worth. Oh, and he has a fourth one that is treated as a Continuous Spell.
 * In episode 65, Shoichi—as Unnamed—almost fell into a pit full of spikes, only saved by Yusaku—as Unknown—grabbing him on time. Not only could the spikes could have dealt severe mental damage, it turns out that if your duel disk is destroyed, you can't leave Link VRAINS, which means you are effectively trapped in a coma.
 * 68:Ai gets to meet two fellow Ignis Windy and the Light Ignis who's now named Lightning.
 * They reveal their intention is to rule the world and dispose of humanity once they lost their usefulness.
 * They try to get Ai on their side, but he naturally refuses. They then capture him and Playmaker and try to tear Ai apart with a Data Storm and use the remains of his data to rewrite him into an ally. Not only did they basically just attempted murder, but they also tried to desecrate his remains afterwards.
 * The Knights of Hanoi are back and are out to destroy the Ignis. We get to see a beautiful shot of Windy's shoddily made Cyberse World burning down.
 * 70:It's revealed what happened to the human Windy is based on. He got seriously injured or died in a car crash, but the worst part is that Windy caused it and doesn't feel even a bit of remorse from it. His reasoning even takes it to a whole other level of messed up. He did this so that he doesn't need to rely on a human partner like Ai and become devoted to them despite the fact the Ignis didn't bother with their partners or humanity as a whole in the first place and only contacted them after they were attacked by their enemies.
 * Also if you think about it, Windy's partner must have a similar age like Yusaku, this means he was barely a kid around 6 to 15 years for this to have happened.
 * While Windy did deserve it, it still is creepy and unsettling to see him impaled by spikes after Revolver defeats him in a duel. And no there wasn't any Bloodless Carnage in this. We could clearly see his injuries being made of red data just like with Playmaker and Revolver in #42. What also doesn't help is that in the preview of the next episode, the holes still haven't closed and are purple all over.
 * This episode also reveals what happened with Jin's consciousness data. Lightning, his partner, stole it and uses it as his puppet. We don't even know if Jin is conscious since he still has the same blank look in his eyes since his first appearance. It's possible he might be in a And I Must Scream scenario.
 * 74:GO is back and it's revealed what he was doing all this time. He underwent an experiment to become stronger, but it's clear that he's not really completely there or even himself. His frame became much slimmer after the experiment especially when compared to how he looked like before and his voice and demeanor became much calmer in a creepy way.
 * 75:GO really is no longer himself because he got an AI chip planted into his brain. During his training sequence, he stopped caring about his health because he started winning and seeing the world in a different way thanks to the AI. Now he no longer cares for anything; destroying Crystal Heart despite what it meant to Earth, capturing Earth despite him not being an enemy Ignis, having fought alongside Playmaker during the Tower of Hanoi, possibly dying during the experiments...he no longer cares for anything as long as he can win and defeat Playmaker.
 * Earth's death. After he is captured by GO on behalf of SOL Technologies, they waste no time dissecting Earth bit by bit until he is completely terminated. Earth, who is normally calm, cool, and collected, started panicking and begging for them to stop because he has free will and is alive, but his pleas are coldly disregarded. Aqua, Flame, and Ai all sense Earth's death, while Spectre also sheds a single tear, uncertain of what it is he felt.
 * From Earth's perspective, he just lost a duel against a human out for him and Aqua and was captured as a result. Earth ends up Strapped to an Operating Table as SOL Technologies scientists take him apart for his data, causing him to slowly lose his memories of Aqua. Realizing what is happening to him, Earth desperately begs for them to stop while Queen and Akira look on.
 * Earth, after his right wrist was cut off: panicking “Stop! I have free will! I’m alive!”
 * Notice how SOL referred to the dismantling of Earth as a dissection. Dissection is a term that is only used for things that are 1) dead or 2) non-living; technically, since Earth is an Ignis—a living being with free will—the correct term would be vivisection. That means SOL does not consider the Ignises to be alive even if they have free will and can think for themselves.
 * 76: It's confirmed that Earth truly is dead according to Ryoken. Since not only was he cut apart, but his data was rewritten into a code SOL Technologies could understand, making it impossible to restore him.
 * Aqua reveals that her Origin, Miyu, is currently in a coma, because of a virus Lightning planted inside of her that Aqua can't cure. This means that Miyu is currently in the same situation as the many Another victims and her Childhood Friend Aoi.
 * 79: We get to see Windy again after he recovered after his impalement and he doesn't really look any better since he still has black markings over his body and half his face is in some kind cast. It's also seems that he's even more insane after his near death experience since his hatred against humanity grew even further, but he also doesn't care about some of his fellow such as being happy about Earth's death or wanting to kill Aqua, because he knew they wouldn't join them.
 * 81: Oh boy. Just when you thought GO's appearance during his duel against Earth wasn't bad enough... he looks even worse come his next encounter with Playmaker, as by that time, he looks like an old man.
 * To the shock of Aqua, not only is GO in possession of Earth's "G Golem Crystal Heart", it is also tainted into a darkened state, thanks to GO's influence over said card.
 * Earth’s fate. The beginning of the episode had Ai believing that Earth had somehow escaped and that Takeru and Yusaku needed to go to VRAINS to save Earth before he was recaptured. Was Earth free? Nope. Turns out his decompiled data was placed into GO’s AI chip. In other words, not only was Earth NOT saved, his desecrated remains are now a part of the man who lead him to his death in the first place.
 * 82: When GO realizes he's going to lose to Playmaker again, his eyes start glitching out in a creepy way. There also is the fact it stated that GO would actually die if he were to continue to stay in VRAINS and not log out and rest. If it wasn't for Akira forcing GO to log out at the last second, he would have died.
 * On the other hand, SOL Technologies came very close at capturing Playmaker and Ai after the former defeated GO by making use of Ai retrieving Earth's data by activating a capture drone which looks a lot like Akira's and Ghost Girl's trap back in #8, but more tentacle and vine like. This would have actually succeeded at capturing them both if it wasn't for Akira forcing GO to log out
 * Episode 85: "True Tears": How about the fact everyone who loses in Mirror LINK VRAINS will get erased. This means that this truly is the **final battle since it's clear that even a single loss is fatal. This is basically the digital version of season 3 of Yu-Gi-Oh! GX.
 * Episode 86: "Wisdom of the Depraved":
 * From the title and summary alone, it's already clear that this duel is full of Nightmare Fuel since it's Lightning Vs Spectre! In one corner we have the calm psychotic Ignis whose hellbent on enslaving humanity and on the other side we have an insane sadomasochistic manchild who enjoyed the Hanoi Project. From the preview alone, they have shown that Spectre hasn't changed at all since he still has those Nightmare Faces. Indeed they have; Spectre and Lightning both pull off glorious Nightmare faces, Spectre especially.
 * Windy revealing that he's captured Frog and Pigeon and tells them to broadcast their duels to the Playmaker/Revolver alliance. Initially they refuse, but comply once Windy applies bomb straps and their necks and threatens to kill them with it if they don't follow his orders.
 * Episode 87: "Chain Destruction": Based on the previews, the Nightmare Faces of BOTH Lightning and Spectre are about to get even more extreme. Lightning in particular looks even more sadistic than Spectre. Speaking of which, Spectre's Nightmare Faces appear more angered than the usual smug/taking joy in other's misery look he generally has.
 * Lightning's Nightmare Faces are terrifying, but the reasons WHY he made those faces are what really sells the Nightmare Fuel. Ai noted that Lighting was the leader of the Six Ignis because he was the smartest of them on top of being calm and collect, and Spectre in the previous episode touched a nerve and he's genuinely aggravated and Lightning when angered is absolutlely frightening and even Ai said he'd never seen Lighting get so angry or act the way he did and after calming down, he proceeds to unleash 'divine punishment' on Spectre and BRUTALLY destroys Spectre's field and defeats him by Destroying and BURNING Sunavalon Dryatreniay to the ground, and keep in mind, this is the card that Spectre considered to be his mother and Lightning knew full well the relationship between the two and decided to destroy/burn it because Spectre pissed him off.
 * Episode 88 "Revenger Windy": Windy's origin is revealed in a flashback. Apparently, he is able to move on from his trauma and live a normal life. Windy then hijacked a car on him under a red moon.
 * Episode 89 "Two Flames Unite":
 * After Windy lost to Soulburner, Flame incinerates Windy, and Lightning refuses to save him. Why? Because he has "no use for the foolish", despite Windy's loyalty to him and all that Windy did for him.
 * The fact that despite all of Flame's efforts to reach Windy, even offering to preserve his data from Lightning's purge, Windy still insists that he hates humans and his hatred will live on as a "curse". This shows that Windy was truly rotten to the core and that there was no saving him, physically or spiritually.
 * With Windy's death, two of the six Ignis are now gone, victims of circumstance and their own actions. Who knows what trouble awaits Ai, Flame and Aqua, especially at the hands of their fellow Ignis and former leader Lightning...
 * The fact that the audience will never get to know Windy's origin; he doesn't even get a name before he's killed. What was he like? Was he able to move on from his trauma of the Lost Incident? As the origin of Windy, was the guy also as twisted and hateful as his Ignis deep down? Or worse, was he a normal and nice guy to begin with, similar to Earth having a twisted partner as Spectre, only in reverse?
 * Episode 93 "Promise With Each Other": Soulburner explodes while also crying, voicing his outrage towards Bohman and Lightning for setting up a Duel between Playmaker and Kusanagi (which ended in Kusanagi's termination), and vows to make both Bohman and Lightning pay.
 * Episode 94: Bohman summons Paradox Hydradrive Atlas, the monstrosity used to tear Cyberse World down. Being too big to fit in the duel field, the cyclopean beast instead ominously sticks its head through the water walls. In-Universe, its mere presence stirs all sorts of negative emotions within Flame, even causing him to glitch.
 * Episode 95 - "Radiance of the Phoenix": Windy wasn't lying when he claimed he'll linger on as a curse within Flame, reemerging from him in the middle of Soulburner's Duel with Bohman. Windy attempts to mutilate Flame and appears to do the same to Soulburner by infecting him with some sort of... substance, only to be stopped by Flame and reabsorbed.
