Nightmare Fuel / Fairy May Cry

Don't be fooled, despite the colorful and badass casts of Fairy Tail and Devil May Cry, both stories are filled with vicious demons and psychopaths armed with horrifying powers. These moments were bound to crop up now and then.

---

General

• The addition of elements from Devil May Cry make the story Darker and Edgier to Fairy Tail. There's a more realistic amount of blood from wounds. Enemies are more dangerous and vicious, with some employing psychological tactics against the protagonists, and while there's still comedy, very few opponents are Played for Laughs.
• In the Vergil arc, Vergil showed his how truly dangerous he is while he beats and kidnaps many members of Fairy Tail.

Fairy May Cry

Opening/Vergil Arc

• In the opening chapter where a red moon causes an opening of the underworld releasing hordes of demons that attack and kill all nearby civilians. Luckily the Fairy Tail wizards and Dante stopped them.
• Clipping the Fairies' Wings: Some members (Macoa, Wakaba, Jet and Droy) decide to show Vergil not to mess with Fairy Tail and try to beat him up. Only for Vergil to show how outmatched they are and trash them around, with Levy looking on in terror and falling to her knees seeing her friends (who she knew since childhood and knowing how powerful they are) beaten by Vergil with just fraction of his power. When he looked at her with his cold eyes she trembled in fear but still tried to fight Vergil using her Solid Script magic. Sadly Vergil No-Sell and just Ominous Walk to her with Levy getting more desperate. She used all she could but Vergil suddenly appeared in front of her, covering her mouth, with the poor girl terrified, before knocking her unconscious.
• In later chapters Vergil showed how outmatched Fairy Tail is compared to him. He even went for kidnapping some members, including Wendy with the poor girl terrified of him and other members fearing for her safety after Vergil took her with him.
• Ch. 13 A Devil's Game has Vergil unleashing three powerful demons to combat the members of Fairy Tail.
• Ch. 16 Demon vs. Spirits
  • Vergil is capable of using Yamato to bypass Juvia's water body, with the young woman screaming in pain, to Lucy's horror.
  • Vergil's merciless Curb-Stomp Battle of Lucy's Spirits one after the other, leaving her increasingly rattled. While Loke lasts longer than the others, he still ends up skewered, and while it doesn't kill him, it is painful to watch, especially for the horrified Lucy.
• Ch. 17 Devil Prince VS Fairy Queen: Just how outclassed Erza is by Vergil once he starts using his Devil Trigger, subjecting the seemingly invincible Titania to a Curb-Stomp Battle. Erza has always been a pillar of strength for the guild, but the fact that even she is not enough to stop Vergil shows how grave the situation is.
• Ch. 18 Epic Clash: Natsu VS. Vergil
  • An In-Universe case for Vergil's captives at seeing just how many of their friends he has beaten already.
  • Just when it looks like Natsu, Gajeel and Gray might be winning, Vergil simply breaks out his Devil Trigger and inflicts a brutal beatdown, with the other members present helpless to intervene.
  • When a desperate Wendy attempts a Sky Dragon Roar Vergil easily avoids it before slapping her across the room. He then gets ready to kill her with Yamato, in a scene dripping with terror before Natsu takes the hit instead. This leaves him with a diagonal cut gushing with blood as well as Blood from the Mouth, and everyone is horrified to see the normally energetic Dragon Slayer laying so still, and so close to death.

Edolas Arc

• Angelo Nelo is a walking source of this. In Edolas, it's mentioned he killed many rebellious guilds like members of Edolas Fairy Tail (including Edolas Lisanna) but things are getting to the point where Mundus later power him into the Onyx Reaper with batlike wings, claws, talons on feet Mandible-like jaws and a double bladed scythe.
• The Edolas soldiers have access to what they call 'magicalisation rays', which fire beams that turn any Exceeds they strike into Lacrima. A single strike converts any being with innate magic into a glorified battery for the kingdom of Edolas.
• The Dorma Anim was so dangerous that after one use the humans of Edolas were horrified and vowed to never use it again. It's mere use drains the already dwindling magic of Edolas to power itself, gaining a black color in the process, and seemingly responding to Faust's Sanity Slippage in his fight with the Dragon Slayers and Dante.
• The magic of Edolas being absorbed through the reverse Anima, causing magical devices all over the country to shut down, in the equivalent of a world-wide blackout. Making things worse, Dante and Mystogan both state that this will cause mass panic and violence, in which many innocents will liekly be harmed.
• At the end of Edolas arc There is someone else watching the reunion. Someone bald with a right blue eye and left red eye, with a burn mark-like a pulsate, looking pure malice.
• Shagotte's vision of Extalia falling from the sky, with Mundus watching in the background, doubling as a In-Universe example, making the elders desperate enough to send one hundred eggs to Earthland under the guise of a 'mission' in an attempt to save the next generation. In the present, they are shocked to discover that Nelo Angelo was merely the herald, shocked that something so terrifying can exist.

Devil Hand

• The tower known as Temen-ni-gru is just as dreaded as canon, especially with Fairy Tail's reactions hearing about its origins. Namely that the tower is meant as a portal to get from the Underworld to Earthland that was constructed by demonic worshippers as well powerful demons like Mundus to conquer Earthland. Sparda, with help of the Dragons (Igneel included), only managed to seal the tower with a complex ritual with the 7 sins represent and was forced to sacrifice two priestesses to seal the tower with the final lock being the two amulets that he gave to Dante and Vergil.
• From Temen-ni-gru, are the Three Brothers, powerful demons, with special mention going to Cragnar, who looks like a cross between a crocodile and a komodo dragon. He proves deadly enough to nearly kill Natsu and Lisanna, and it takes two of Natsu's most advanced techniques to take him down. Then the end of the chapter reveals they were simply minions, with the higher ups being much more powerful and vicious, despite being human.

• Relating to the above, each of the top members of the guild count in this in their own way. Though Vergil has plenty of previous entries highlighting just why he is so feared even amongst Fairy Tail.
  • Mammon, the sin of Greed, might be more of a joker than the rest of the Sins, but his Gold-Make magic makes him incredibly dangerous in a fight, capable of besting Ultear. The horror aspect is best displayed when he turns Juvia into a gold statue, complete with her fearful expression, and nearly does the same to Gray! In fact, he very nearly won, if not for Ultear interfering out of revenge.
  • While Belphegor is the definition of Brilliant, but Lazy, being the sin of Sloth, his powers are no joke, letting him create scores of ghastly minions like minotaurs, lycans, werebats,and skull dragons. This was enough to easily overwhelm the likes of a heavily armed Lady, and nearly did the same to the likes of Trish and Modeus. Even when they survive, he simply uses more magic to merge with all his familiars, and would have killed them if not for Modeus' Devil Trigger.
  • Satan is The Brute of the seven sins, befitting Wrath and one of the darkest examples of a Blood Knight in the story, showing great glee at dishing out and taking attacks, making fights with him a very prolonged and painful experience. In his default state, he is already a Lightning Bruiser, but his magic lets him power up and grow in size the more hits he takes, giving him full-blown The Juggernaut status.
  • While Leviatha, sin of Envy, has a Freudian Excuse (and doesn't even qualify for Enfant Terrible), she counts by virtue of seeing how far a child can be twisted by her Dark and Troubled Past, willingly participating in a plan to bring about The End of the World as We Know It. Her copy magic makes her a nightmare to face as well, bringing the powers of Fairy Tails own members to bear on their friends and family, even troubling the likes of Erza and Mira. It's terrifying to imagine her as a dark wizard as an adult.
  • Asmodeua, the sin of Lust. Dear god, Asmodeua. Not only is she creepy as hell, gleefully identifying as evil with dark colors and a spider motif, there is also her 'hobby'. Even a hardened criminal like Angel was reduced to a quivering wreck after less than a day in her 'care'.
  • Beelzebub, might actually top the above Asmodeua. While Adrian is a Creepy Child at worst, his 'magic' (really a curse) uses a Take Over for a being called the Wendigo, an Extreme Omnivore with a sheep skull that devours everything in its path to sate its bottomless hunger, including animals, heat and even people. Unlike most Take Over mages, who remain in control, the Wendigo takes over whenever Adrian lets it out, running rampant and leaving the poor child to see the havoc his body has wrought. Even the likes of Elfman and Mira are terrified of it, with the latter even saying it "makes [her] Satan Soul look like Peter Pan". Despite fighting together, the siblings were unable to defeat it, coming very close to being its newest victims if not for Adrian's Heroic Sacrifice.
    • The most unsettling part is no one is sure what the Wendigo is. Experienced Take Over mages like Mira and Elfman have never heard of it, its not a demon or any kind of animal and Adrian's backstory doesn't shed any light on its origins. It just showed up one day at his village, attacked and cursed the boy with possession when he fought back and he only regained consciousness after the thing had eaten every animal and human in the village, including his family. Small wonder the kid became a Death Seeker.
  • Iblis, sin of Pride and leader of the seven sins. Standing head and shoulder above most dark wizards and demons, her mastery of her Morning Star magic and immense magical power makes her more formidable than even Erza (according to Dante) and was able to put the like of Dante on the ropes. What really cements her position on this page is her reaction when she starts to lose, showing the scary part of having too much Pride. After frantically denying that she could lose, she decides to use her most powerful spell, despite her life not being in danger, a black hole, yelling to Dante and Happy that kill them with her last act, clearly unhinged. Scary to realize such a powerful and dangerous magic was in the hands of someone who was one loss away from what seemed to be a low-tier Suicidal Cosmic Temper Tantrum.
  • And of course, Arkham, the one who brought all of the above, and Vergil, together. The man is a scarily competent strategist, with his ruthlessness and manipulative nature letting him get everyone to play into his hand, even managing to Out Gambit the likes of Vergil, who was by his side almost the entire time. The fact that he's considered worse than actual demons tells you everything you need to know about his character, even before getting into what he put his own daughter, Mary/Lady, through, traumatizing her in the process. Then there's how he was willing to exploit Sheree/Leviatha and Adrian/Beelzebub's respective horrifying circumstances to manipulate the two into joining what is essentially a cult of assorted criminals and monsters, even experimenting on the former, and showed no hesitation in attacking Wendy, displaying plenty of traits consistent with The Sociopath. Overall, Arkham cements himself as one of Fairy Tails vilest enemies, earning nothing but scorn from the entire guild.

Tenrou Island

• Yomazu and Kawazu have gained demon powers, meaning that they are a lot more dangerous than canon. This gets further enhance when Job (having undergone Sanity Slippage) forcibly empowers them with demonic energy from his Devil Slayer powers, turning them into little more than savage beasts.
• Grimoire Heart's Eight Kin of Purgatory are just as, if not more, terrifying than they were in canon, to the point that even Fairy Tails strongest members are barely able to eke out a win in some cases.
  • Azuma makes his debut managing to launch a surprise attack on Wendy, a Dragon Slayer, and displays enough power to annihilate a small fleet of Magic Council airships, killing the hundreds aboard. His magic lets him move across the island, undetected by all but the most experienced fighters, and enough destructive for levelling the aforementioned air fleet by his lonesome. Only his Blood Knight and Noble Demon tendencies prevent him from being an absolute nightmare.
  • Zancrow is an Ax-Crazy maniac who is willing to murder his own men just for calling Natsu strong and when fighting Natsu, Wendy and Lisanna, expresses his desire to rape the girls solely because he can. What's more, he wields Flame God Slayer magic, which creates black flames that not even Natsu can No-Sell, even burning the Fire Dragon Slayer!
  • Kain Hikaru in canon was a bumbling villain whose voodoo magic made him a source of comedy, despite his durability. Kain Hikaru here has advanced knowledge of physics and chemistry, letting him weaponise his ability to use his voodoo magic on himself, whether it's making his body into diamonds, magma or light, and comes dangerously close to killing Trish, by slowly crushing her skull no less. Trish and Lucy are forced to flee, and only the likes of Dante and Cana are able to get the edge on him in a fight. Even while the devil hunter is winning, Kain manages to swipe a few of his hairs and shows just how terrifying his magic can be, quickly turning the tide completely against Fairy Tail and rendering one of their most powerful members helpless against his allies onslaught, showing a sadistic glee in using his powers to inflict pain.
  • Rustyrose has the lost Arc of Incarnation, an Imagination-Based Superpower with seemingly no limits that lets him run roughshod over nearly all his opponents. Even with Evergreens stone gaze, she and Elfman are unable to defeat him.
  • Merudy is a seemingly emotionless girl who wields Magility Sense lets her connect the physical and emotional senses of people. Sounds nice, except she uses it to inflict pain upon several of her opponents at once using Juvia as a proxy to hurt Gray, despite him being nowhere near that fight. The fact that she is still a child makes it clear how much Grimoire Heart can corrupt those they come across, especially given her hatred for Gray despite never having met him.
  • Ultear, the leader of the Kin, and wielder of the lost Arc of Time magic, which lets her alter the time of any inanimate object and plants, whether it be regress them to a complete state, reverse the trajectory of projectiles, or age them into dust. The woman herself proves to be quite ruthless and manipulative, putting on an act to trick Gray into pulling off a Heroic Sacrifice against Hades, and jumping right to killing him when that fails. This power even lets her put the likes of Dante and Lady on the backfoot, and she shows demented glee in their attempted execution of the younger son of Sparda.
  • Caprico's entire magic is made of this, using an inverted summoning contract that functionally lets him enslave human warriors, having legions of them under his command! What's more, his magic can affect those he hasn't even subjugated, with the human members of Fairy Tail being unable to land a single attack on their fight, and are forced to leave it up to Trish (a demon) and Loke (a Celestial Spirit).
  • Original character Job, acts like an evil priest praising Mundus, and is one of Grimoire Hearts deadliest members, wielding Holy Devil Slayer magic, and being devoted to their 'holy mission' of unleashing the Deon Emperor upon the world. This gives him a vast array of powers, including lasers, LaserBlades, teleportation, light shields and light based explosions, in addition to being able to consume his element, i.e., ambient light to heal his wounds. What's more, his magic proves capable of negating Dante's healing factor, handing him his first decisive defeat (besides Vergil) in the story, even when Lady was backing him up, and the two are forced to flee!
    • It gets worse. After coming back from a previous defeat, he is notably more unhinged, revealing that Devil Slayer magic has corrosive effects on the mind of the user without sufficient discipline, hence his Badass Preacher persona. He completely gives into the madness, acting much more animalistic and fighting like it too, a far cry from the composed opponent from before. Also serves to illustrate just how dangerous using demonic power can be.
• Outside of the Eight Kin, there is Bluenote Stinger, a Gravity Master so powerful even the rest of Grimoire Heart is weary of him, proving capable of amplifying the gravity of an area to such an extent that even a powerhouse like Natsu is unable to stand! He also proves durable enough to No-Sell Cana's attempt at Fairy Glitter, coming very close to killing the group then and there, if not for Gildarts Big Damn Heroes moment.
• Hades, the master of Grimoire Heart is likewise enhanced, having gained power through the use of demonic power. And not just any demonic power, he gained his 'gift' from Mundus himself! He only has two fights in the arc, first taking out Makarov with minimal injury, and at the end fighting a collection of Fairy Tails strongest members (including a returning Laxus) in rapid succession with no signs of fatigue. Even after a combined assault from Dante's Devil Trigger and Natsu's Natsu's new Lightning-Flame Dragon Mode, he's still able to keep going, even revealing that his Magical Eye lets him summon a horde of demons, wreathed in shadows. The main reason the heroes won is because the Exceeds managed to destroy his power source, and even then, it was a close call.
• As per canon, Zeref's curse is a big source of this, making him a sporadic Walking Wasteland that randomly emits a wave of energy that kills everything around him! It even manages to render Dante clinically dead for a few seconds. What's more, while Zeref himself spends most of the arc in despair over the damage he causes, at the end he confronts Hades (and his master Mundus) in a chilling state of Tranquil Fury, paralysing the remaining Kin with fear and killing the master of Grimoire Heart, displaying control of his curse for the first time. What puts this here instead of awesome is that he makes it clear that he has discarded his morals to do so, and makes it clear that while he wants to defeat Mundus, he has no qualms how many enemies he makes in the process.
• This arc gives our first glimpse of what Mundus can do and it is terrifying! In the flashback alone he managed to inflict a complete Curb-Stomp Battle on Precht, despite only having a fraction of his power available, before proceeding to Mind Rape him into a Face–Heel Turn, turning him into the merciless Master Hades seen in the present. When Hades unleashes his full demonic power on the exhausted Strongest Team (bringing them to their knees), Dante notes that he is less powerful than Mundus, notable since Hades himself was on the giving end of a Curb-Stomp Battle against several of Fairy Tails strongest members.
  • The end of the arc has him manifest before an enraged Zeref, from Hades just-killed body no less, taunting the Black Mage about giving into his curse. He admits that the entire formation of Grimoire Heart was to draw the Black Mage out of hiding, showing he can also be a scarily competent Chessmaster on top of his vast powers. The fact that Zeref is emerging into the world means everything is going as he had hoped.
• Just when it looks like Fairy Tail is in the clear, in comes another threat, Acnologia! His mere presence causes the Magic Council forces to flee, and inspires complete fear in the likes of Gildarts and Modeus, with the latter even remarking that the beast has a reputation as the Dragon Butcher in the Underworld, with high ranking demons being terrified and only Mundus is more powerful than him. It shows throughout their encounter, with everyone in Fairy Tail unable to do more than scratch him, after which he prepares to finish them off with a single attack. He more than lives up to his reputation.

Devil's Retribution

Seven Year Gap

• The fact that even sealed away Mundus is a big enough threat that Sparda and his in-laws feared what he would do to the Heartfilia's if he learned they were Eva's birth family. Just how much influence does he have over the demons active in Earthland?
• Demons have become much more active in the past seven years, and while not a threat to mages, can still massacre civilians. Some can even shapeshift into humans, adding all kinds of Paranoia Fuel.
• Sid reveals the existence of the three demon kings, Abigail, Argosax, and Urizen, three entities below Mundus, but well above every other demons in existence.
• According to Brad, the Underworld has some how gotten worse in the past seven years. All sorts of demons are trying to get out and gain more power.
• Natsu brings up the fact that this may not be the first time the masked demon has killed someone under the guise of being a Jackass Genie. Who knows how many people its killed and innocent lives its destroyed pulling the same routine.
• The masked demon shows up, promises people wishes, and then frames them for murder at the first instance of them using a euphemism. It left Kerry racked with guilt over 'killing' his best friend and tries to do the same to Natsu and Grey. Erza and Natsu note there's no telling how many other victims it might have had prior to this.
• While the demon guards running the Devils Prison are no match for Dante and Erza, they grossly outclass any ordinary human, and have collars that restrict a mages access to their magic. The fact that they essentially have free reign to arrest people around town and lock them up in prison without even letting their loved ones see them raises all sorts of horrifying implications. Hell, their game of 'tag' practically confirms this.
• How Kings magic works, essentially tricking people into unknowingly making a Faustian bargain, granting them supernatural good luck and stealing their souls whenever they lose. What's more, it makes whoever holds the item become a gambling addict, even managing to affect Dante of all people.
  • While under the effects of one of Kings items, Dante's attitude skips over unnerving and goes straight into terrifying, pulling out a gun on Erza with an unhinged smile.
• The siren that possessed Elena somehow corrupted the music in her albums, causing many of her fans to go insane, with some even committing murder or suicide. The sheer scope of the havoc one sound based could wreak with the influence of one singer is frightening.

The Order of the Sword

• The arc opens with a vision of the world engulfed in flames and a madman laughing at the 'Savior' bringing down destruction. Counts In-Universe since this is a recurring dream the Archbishop of Zentopia has been having.
• Something is burning down churches all over the kingdom, and leaves bodies behind in each case. Evidence suggests that in addition to fire, some form of acid and blades were used, with even the Rune Knights being stumped as to what could have caused it. Fairy Tail themselves point out it could be a demon or a psychotic human, a harsh reminder that there are plenty of people who can cause such death, be they demon or mage.
• Mary Hughes' People Puppets magic lets her force allies to attack one another, made all the worse that such a power is in the hands of such a Sadist.
  • Throughout her debut chapter she repeatedly uses this on Trish, which dredges up the woman's memories of her time serving Mundus.
• While usually friendly, Nero's attitude is terrifying once he hits his Rage Breaking Point, slamming Dante headfirst into the ground and later beating Trish unconscious (after sucker-punching her). His attitude makes it clear he is very close to delivering a No-Holds-Barred Beatdown to the next person that interferes.
• Mary Hughes uses her People Puppet powers to 'exorcise' Mira's Satan Soul from her body, giving a Sadist the use of one of Fairy Tail's most powerful members powers. She then proceeds to use said powers to brutalize Mira's friends and brother, showing just how horrifying said powers can be when not in the hands of a Nice Girl like Mira.
• The Infinity Clock's mere activation generates an ominous aura that can be felt all over Fiore. Even powerful mages like Makarov are unsettled with the feeling. Gets even worse when we learn its origins, as apparently Sparda, Anna Heartfilia (explicitly stated to be the strongest Celestial Wizard) and Zeref working together were unable to destroy it, only being able to seal it away.
• The debut of the Neo Oracion Seis, having replaced half their members with people even more powerful and vicious than their predecessors, and the remaining members having Took a Level in Badass. Their debut has them wiping the floor with some of Fairy Tails most powerful members. To elaborate:
  • Midnight not only refined his Reflect magic to the point it can affect Byro's Anti-Magic, and can combine it with his new Darkness magic, based off of Brains. His new favorite tactic seems to be trapping foes in a sphere of his Reflect magic with powerful bolts from his Darkness magic. Incredibly painful as Dan and Byro can attest.
  • Racer has shifted from slowing opponents down to full on Super-Speed, and uses it to deliver a high-speed No-Holds-Barred Beatdown on Grays group. Even worse, throughout the entire scene, and in subsequent chapters, he is constantly snarling, using brief sentences and having a disturbing fixation on killing people, giving the impression of a vicious wild animal.
  • Erigor makes a return with the title and an appearance of the 'Grim Reaper', wielding a Sinister Scythe and having upgraded his Storm magic to include razor sharp winds and lightning. Even more unsettling is his attitude throughout the entire encounter, showing no emotion and having to be reminded of things that happened minutes ago.
  • Gilver officially appears before Fairy Tail, having somehow returned from death. Proves to be a match for Dante, which is a very scary concept. Painful to watch him use several features of his katana to inflict all sorts of wounds on the son of Sparda, most notably when he impales him and unleashes a whirlwind on his internal organs.
  • Finally, there's Gloria, who remains focused on debilitating her opponents save for the occasional taunt. Her combat skills and powers prove to be a deadly combination, overpowering the likes of Mira and Freed, made all the more terrifying by the fact that her favorite attack seems to use her Ride the Lightning and knives to simultaneously shock and slice up opponents. In her 'fight' with Trish, she proves capable of overpowering the she-devil, and manages to successful steal the Devil Sword Sparda, putting the powerful artifact in the hands of the villains. The fact that she is apparently a clone Agnus made using Trish's blood (and subsequently strengthened, only adds to the scary factor, showing how terrifying she would be as a villain.
• Guttman Kubrick, a demon the Order imprisoned years ago is recruited for their mission, and possesses a dangerous power called 'Rupture' which he can use to shatter objects or detonate the magical and/or the demonic power of others, essentially turning them into living bombs. The fact that he appears to be a Manchild following Sanctus' orders makes the whole thing much more unsettling.
• In Divide and Conquer, Kinana begins to act possessed, moving about in a daze and ominously muttering words (implied to be Cobra's internal monologue) about destroying the world. She then proceeds to carve a series of runes into the wall with a fork, bringing to mind all sorts of horror movies.
• The Order is revealed to have found Sparda's corpse, and used it for all sorts of experiments. The fact that they twisted the body of such a powerful and noble individual is horrific.
  • Agnus also mentions that they attempted to clone the Dark Knight and failed, raising all sorts of horrific possibilities.
  • Related to the above, Agnus says they merely found Sparda's corpse, which raises the question: what was able to kill freakin' Sparda?
• Half of the Neo Oracein Seis have undergone the Ascension ceremony like the Order of the Sword members, giving them black-winged demonic forms called 'Caduto'. The fact that these monsters have even more power at their disposal (taken from Sparda no less) is nothing short of terrifying.
• As if Erigor's attitude wasn't enough, it gets worse when his 'Reaper Caduto' form restores his mind, giving him an eerily calm type of Ax-Crazy. He then gives a horrifically detailed threat of how he's going to kill Wendy and use her corpse to taunt Natsu. Oh, and apparently he gave up his soul in the process of getting his new power, which raises all sorts of horrific implications.
• Gildarts, Laki and Morrison discover a comatose girl being kept in said state. Her name is Michelle Lobster, which raises the question, who is the girl that has been hanging around Fairy Tail all this time?
• Sanctus and Midnight plan to use Kyrie alongside two others to form the Saviors core, Kyrie in particular to make sure the power doesn't rip them to pieces.
• The Order of the Sword and the Neo Oracien Seis manage to do it. They activated the Infinity Clock, and use it to power the Savior. The mere activation causes the sky to darken as red clouds begin to emerge all over Fiore. The villains now have a weapon of mass destruction that Word of God has called 'a walking apocalypse'.
• The fact that merely four Gladii can put experienced mages like Alzack and Bisca on the back foot, which Agnus calls some of his weaker creations.
• Sanctus and Midnight reveal that they can influence the thoughts of people through Imitatia, causing all sorts of Paranoia Fuel. Even more horrifying, against people without magic, the effects are apparently strong enough to remotely induce a brain tumor, which they did to Jude, and can apparently do so without her knowledge.
• The Savior more than lives up to its title of a walking apocalypse, causing unnatural disasters all over Fiore just by existing. Said disasters include raining fire, lakes turning to acid and tornadoes of metal. Mage guilds all over the land have to intervene to minimize casualties.

Grand Magic Games

• Sparda reveals that when he found Zeref again after he was cursed by Mundus he had ripped out his own heart in a desperate attempt to kill himself.
• When Sparda tells Zeref's origins to Fairy Tail, he drops a major bombshell: he helped Zeref create the Etherious. Using Sparda's own power and Zeref's Life Magic, the Etherious were created to kill Zeref if he ever fell into madness over Mundus' curse, and if Sparda was unable to find a cure to his magic. They were sealed away by Sparda using Body-Link Magic and could only be released by him. However, when Sparda died, the Etherious were released. While some were akin to wild beasts such as Deliora, others had their own sentience and intelligence. The rampage Deilora went on that killed Gray's parents and later Ur was a result of his programming to kill Zeref, merely seeing everything before him as an obstacle that was meant to be eliminated. What that also means is Sparda, albeit unintentionally, had a hand in the creation of Tartaros.
• During Dante's confrontation with Jiemma, a Rhetorical Question Blunder from him reveals that the master of Sabertooth actually considered raping Yukino for her failure in a single match, and only refrained because he considers her too weak to bear his children.
• Obra manages to escape when Raven Tail is arrested. Sapphire freaks out as a result and is completely terrified of the little imp. Keep in mind that Sapphire is an S class wizard who was willing to go undercover in a Dark Guild for months, is shown to be at least on par with Natsu, and together with Laxus took down the Raven Tail team including the Guild Master and she is terrified of Obra. What exactly is he capable of that would make her so scared of him? Whats even worse is that despite most of Raven Tail being arrested with Obra free their plans can still continue.
• The Eclipse Project finally reveals how Sparda died. When Dante and Vergil turned eight, Sparda left home in order to fight an ancient enemy in order to protect his family. The fight went on for days and even leveled a mountain range, but in the end, Sparda lost his life. And the one that killed him? Acnologia.
  • Even more horrifying is Sparda said that Acnologia had become stronger than when he first fought him 400 years ago, and back then, Acnologia stood on even ground with Sparda to the point that the Dark Knight needed help from Igneel, Kurenai and others just to push him back, and the best they could do was force him to retreat, after destroying an entire countryside in the ensuing fight!
  • Not only that but unlike Mundus who has been sealed away and can at least not directly threaten Earthland, Acnologia is still at large and with the dragons all but extinct and Sparda dead there is no one in Earthland who can currently match him.
• Just as soon as Gajeel and Rogue manage to make peace during their fight, a demonic entity suddenly takes over the latter's body, and attacks Gajeel. The entity, calling itself Legion, is revealed to have been formed from the dark energy Rogue absorbed over the years from fighting many demons in hopes of growing stronger. Not only does Legion have access to all of the demonic energy in question, but it can even use Rogue's Dragon Slayer magic, putting Gajeel on the ropes for a time.
  • The scary part is even after Gajeel manages to win the fight, Legion states that its time will come, relenting only because Rogue's body can't handle so much power right now, and its time will come. Gajeel and Rogue better watch out in the future...
