Tartaros is the last of the three guilds of the dreaded Balam Alliance to make an appearance. Several of their members, including their guild master E.N.D., are demons from the Books of Zeref. Founded by Mard Geer Tartaros, the guild's goal is to wipe out all magic on the continent using the Magic Council's ultimate weapon Face in order to awaken E.N.D. and reunite with their creator.
In X791, Tartaros destroys the Magic Council with the help of two Saber Tooth defectors. In retaliation, Fairy Tail declares war and launches an attack on the dark guild's base.
- All for Nothing: All that destruction of the Magic Council, murder of the councilors, and fighting with Fairy Tail in the name of awakening their master, and in the end they failed miserably. The activation of Face was foiled by Fairy Tail and the dragons and therefore they couldn't awake their master. At least half of the Demon Gates died, including Mard Geer, their base was nearly destroyed, and the book of E.N.D. was taken away by Zeref.
- And I Must Scream: All the surviving demons were eventually absorbed into Mirajane's ultimate Satan Soul, Mirajane-Alegria. Seilah got taken over as her own separate Satan Soul, Mirajane-Seilah.
- Antagonistic Offspring: The true purpose behind their creation. Zeref created the demons and made them so powerful specifically so that they could kill him.
- Badass Crew: A more villainous example, with each demon being very powerful and mortally dangerous on their own way, not only being able to go toe-to-toe with Fairy Tail's strongest members, but also damn near killing them each and every time.
- Bus Crash: If there were any survivors, assuming they weren't absorbed by Mirajane into her Satan Soul: Algeria, they are guaranteed to have died once Zeref is finally killed, as their life force is tied to his.
- Curse: Their method of attack is curse power, which is distinct from magic power as it draws purely from negative emotions.
- The Dreaded: Despite the shortage of information on its account compared to Oraciòn Seis and Grimoire Heart, Tartaros quickly became the most feared dark guild thanks to subsuming many of the proxy guilds of its allies and becoming the de facto most powerful dark guild on the continent. When the truth of both its identity (a guild filled with genocidal demons created by Zeref) and its goals (the destruction of all magic in order to awaken the most powerful demon of all and the destruction of mankind) were finally made known, it only justified and amplified that fearsome reputation.
- Egopolis: It's implied by Mard Geer's full name, Mard Geer Tartaros, that the Underworld King named the guild after himself when he's revealed to be the one who really created the guild, not E.N.D..
- Eldritch Location: Their headquarters, Cube, is actually a Giant Flyer that can absorb anything that is on its body that isn't one of the demons (except the Mooks), turning its victims into parts of the architecture.
- Evil Power Vacuum: With the Oración Seis imprisoned by the end of the Nirvana arc, and Grimoire Heart more or less defunct as a guild due to deaths and defections of its strongest by the end of the Sirius Island arc, Tartaros stepped in during the intervening seven years as the final member of the Balam Alliance and assimilated many of their proxy guilds into their own.
- Humanoid Abomination: While exactly how humanoid in appearance they are varies between each member, none of them are human (at least not anymore for some), but are rather demons. Their One-Winged Angel forms show off their true appearances and subsequently what they really are, often doing away with whatever semblance to humanity they had.
- Humans Are Insects: By principle, these demons view humans as being lower than insects. Suffice to say, they're pretty shocked when these "puny humans" start doing them in.
- In-Series Nickname: Tartaros is occasionally referred to as "Zeref's Bookshelf," due to the fact that the vast majority of their members are demons from Zeref's books.
- I Will Find You: Kyôka, and later Zeref himself, have stated that despite being demons that Zeref created, Tartaros has never actually met Zeref in person, and it's one of their life's dreams to finally get the chance to do so, which explains a lot of their actions and their lack of empathy for humanity. Kyôka pretty much flat out states they're only doing what they think Zeref would want of them. This is because it's "coded" in them to serve Zeref regardless of their well being.
- Kill All Humans: While their endgame is to resurrect E.N.D. and return to Zeref, they figure that wiping out humanity would make a good bonus, and they're poised to do it through their plans.
- Killed Off for Real: A surprisingly large number of its members are dead by the end of their arc compared to most antagonists. What's particularly notable is that the protagonists, who are usually averse to lethal force, are directly responsible for the majority of their deaths. Even the story arc's survivors are confirmed to either been absorbed by Mirajane into her Satan Soul: Algeria or have died together with Zeref, as that is how they were designed.
- Knight of Cerebus: They start off the arc by killing most of the Magic Council, and their arc includes several attempted assassinations on the former Council members, Deadly Gas attacks that kill hundreds of innocent civilians, and torture.
- The Legions of Hell: Tartaros is made up almost entirely of demons from the Books of Zeref.
- The Magic Goes Away: Their goal to revive E.N.D. entails activating Face, a magic pulse bomb capable of wiping out all magic on the continent, which they believe is preventing their master from leaving his book. Since Tartaros uses curses instead of magic, this would also leave humanity virtually defenseless against them.
- Made of Magic: The name of the demons of this guild, Etherious, comes from the Ether-nano (a.k.a. raw magic energy) from which Zeref created them.
- Meaningful Name: In Greek Mythology, Tartaros is an area of the Greek underworld reserved to torment souls that are judged to be evil, making it the rough equivalent of Hell in other religions. All of their high ranking members are demons from the Books of Zeref, who believe they are passing judgment on humans.
- Mooks: Their footsoldiers come in an armored design with magical staffs to use during battle. It's implied both by the manga/anime and more explicitly in FAIRY TAIL that most if not all of them are lesser demons created through magic and/or forcibly transforming humans.
- No Ontological Inertia: Zeref designed his demons to die together with him. This naturally guarantees their deaths once he is finally killed by Mavis.
- Ominous Floating Castle: Cube, their base of operations, is a giant floating cube but the demons mainly remain inside a worn down castle. It can be turned into Pluto's Grim, which destroyed part of Fairy Tail's home town before being sliced up by the Celestial Spirit King.
- One-Winged Angel: Most members have shown the ability to enter their "Etherious Form", changing into their true forms and enhancing their powers.
- Orcus on His Throne: They did absolutely nothing on-screen before their own arc began, and were only mentioned in passing with almost nothing being known about them. And then they made their on-screen debut in a very big way.
- Our Demons Are Different: Tataros's high-ranking members are all demons from the Books of Zeref. They are distinguished from other demons (like the ones on Galuna Island) with the name "Etherious".
- Person of Mass Destruction: Almost all of its most important members possess a vast scale of power and so deadly skills that they represent a serious threat across the continent of Ishgal. Moreover, Pluto's Grim, once activated, would have dispersed an entire city on its own with ease if it had not been for Celestial Spirit King.
- Poisonous Person: In a sense; some have bodies that contain Devil Particles, which are toxic and potentially lethal to humans, especially so to wizards. Tempester in particular used these to launch a magical equivalent of a chemical weapons attack on Hargeon.
- The Power of Hate: "Curses" are a type of magic that draw their power directly from negative feelings such as hatred.
- Really 700 Years Old: Most of the more human looking Etherious look pretty young, but they have been around for nearly as long as their creator Zeref.
- Religion of Evil: Many who have witnessed their gatherings describe them as a cult that worships demons. They're only partially correct; they don't worship demons, they are demons. However, they do appear to worship Zeref himself, with a shrine set up in his honor in their inner sanctum.
- Resurrective Immortality: Their headquarters has a special regeneration facility called Hell's Core, where they can instantly teleport once they're killed.
- Sorting Algorithm of Evil: The last part of the Balam Alliance to appear, and by far the most dangerous. Grimoire Heart was more infamous, but mostly because they were more visible as a dark guild. Their battle also leaves Fairy Tail with physical and emotional scars that would over a year to completely heal
- Teeth-Clenched Teamwork: Many of the members do not get along with each other; at one point, one of their elites gleefully kills a subordinate because he found her to be annoying.
- Undying Loyalty: To Zeref, to the point where they're willing to wipe out humanity and even give up their own lives for no other reason than because they think it's what Zeref wills them to do.
- Unwilling Roboticisation: A variant occurs in which they have the ability to turn humans into demons. After they try to do this to Mirajane, it's implied that not all of their members were willing.
- "Well Done, Son!" Guy: To Zeref, despite never having actually met him in person. Their primary goal is to meet him for the first time. Most of their villainy is merely them doing what they think Zeref wants from them.
- You Have Outlived Your Usefulness: They wiped out at least one subordinate dark guild (Succubus Eye) for failing to live up to expectations when they prepared to go all-out on their Face plan (and the ill-fated Council meeting mentions more being wiped out), and it's implied they kept the stronger members of said guilds to turn into demon fodder.
Mard Geer Tartaros
Voiced by: Toshiyuki Morikawa (Japanese), Vic Mignogna (English)
The Underworld King of Tartaros, second only to E.N.D. in power and rank among the rest of the guild. Mard Geer serves as acting guild master since E.N.D. is sealed away in his book, which he carries at all times. His Thorn Bramble curse allows him to produce an endless deluge of thorny vines that skewer his victims.
- Agent Peacock: An arrogant, Long-Haired Pretty Boy who creates thorns and petals as his weapons, and effortlessly curb-stomps three Dragon Slayers at once.
- Alas, Poor Villain: While Mard Geer is a true demon, his death at the hands of Zeref is quite sad, considering that everything he did was to fulfill his creator's desire and said creator was unmoved by such dedication. Gray, who has every reason to hate demons, is infuriated at Zeref killing one of his own creations so coldly.
- Arch-Enemy: He is this to the Celestial Spirit King, even dueling each other at one point in the past, though their battle remains unconcluded.
- Arc Villain: He, rather than Master E.N.D., serves as the main villain of the Tartaros arc. This is made all the more apparent when Zeref reveals Mard Geer to be the true founder and leader of the guild who used E.N.D. as a figurehead to manipulate the other demons.
- Authority Equals Asskicking: As the de facto leader of Tartaros, he is also the strongest member of the guild, if not all of Zeref's demons apart from E.N.D., whom Mard Geer merely parades as guild master to command his subordinates' respect.
- Badass Baritone: Toshiyuki Morikawa gives him a deep tone of voice, as does Vic Mignogna in his Etherious Form.
- Badass Longcoat: He wears one of the coolest and fanciest in the series; it's white and black all over, and tattered at the end.
- Bad Boss: Condemns many of Tartaros's own soldiers to be absorbed along with the heroes when he transforms their fortress, keeps sit on his throne and smiling after knowing that at least half of the Nine Demon Gates were defeated, and tortures Kyôka as punishment for thinking humans are even worth the effort to torture.
- Big Bad Wannabe: His end game for reviving E.N.D. is actually so he can use the demon to kill their creator as intended and hog the glory for himself. Zeref reveals later on that Mard Geer found the Book of E.N.D. and formed Tartaros all on his own with the express goal of pleasing their master. However, Mard Geer's ultimate attack isn't enough to defeat Fairy Tail, proving just how far out of league he was from the beginning.
- Bilingual Bonus: The name of his Alegria curse means "Happiness" in Italian.
- Bishōnen: As if he weren't enough of one of the series' defining examples of a Long-Haired Pretty Boy, his Japanese and English voice actors are experts at the Bishōnen role.
- Bishōnen Line: His Etherious Form, compared to those of the other male Tartaros members, subverts the usual method of just becoming a bigger, badder, more monstrous version of themselves, instead gaining a form that looks more like he's wearing an extremely impressive suit of armor with wings and a helmet, even maintaining his overall original size and ponytail.
- Blind Obedience: He wants to kill Zeref not because he hates him, but because he knows Zeref created him for that very purpose. He's completely broken when he's unable to fulfill his once purpose for living.
- Blue-and-Orange Morality: Mard Geer doesn't really hold any malice towards humans nor is he interested in taking over the world. He simply desires to fulfill the purpose he was created for which is killing his creator Zeref. He only really comes into conflicts with light guilds due to his lack of empathy as he causes destruction across Fiore without caring what happens to the humans since he regards them as ants.
- Break the Haughty: Right before his death, he's been completely pounded into the ground and lived long enough to see his plans crumble apart, leaving him a sniveling wreck.
- Curb-Stomp Battle: His "fight" against Sting and Rogue consisted of him nullifying everything they had using only one hand, while he takes his time Just Toying with Them for his own amusement. All while Sting demands he take them more seriously.
- Death by Irony: Killed by Zeref himself after causing the entire events of the Tartaros arc, which revolved around reviving E.N.D., supposedly the one thing that can stop Zeref.
- Dissonant Serenity: Wears a Psychotic Smirk on his face during the heat of battle against titans like the Celestial Spirit King, to skilled warriors like the Twin Dragons.
- Dragon-in-Chief: While he is technically The Dragon to E.N.D, because the latter is still trapped within his book, Mard Geer is the de facto guild master of Tartaros during E.N.D's absence. In fact, Zeref admits that Mard Geer really was Tartaros's master in all but name, and he used E.N.D.'s book to rally the other demons together.
- Eerie Pale-Skinned Brunette: A running theme with Tartaros, as well as with Zeref.
- Evil Cannot Comprehend Good: This demon just does not see what the big deal is with humans and their feelings. This is Lampshaded in the anime by the Celestial Spirit King, who pities him for his incapacity to understand concepts such as love and trust.
- Evil Genius: He's the guy who came up with the technology used for Tartaros' Resurrective Immortality and Unwilling Demonization.
- Eviler Than Thou: To put things into perspective, Kyôka had Minerva—a woman who previously tortured her opponents in a fighting tournament—shaking in her boots. This guy is so terrifying that when he tortures Kyôka, she "thanks him for the privilege", and then reacts with horror as he callously wipes out his own Mooks.
- The Extremist Was Right: Despite how extreme his methods are, he has a very good point that his plan to destroy all magic would have starved Acnologia to death.
- Final Boss: In FAIRY TAIL, as the Tartaros arc is the last one covered by the game.
- For the Evulz: He knows that Zeref created the Etherious to kill himself, yet Mard Geer justifies involving humanity as weeds in his path that he can't be bothered to step around.
- Flash Step: In his fight against the Celestial Spirit King, he dodges absolutely everything thrown at him. In a series where Super Speed is a ridiculously common power, him simply side-stepping an attack that leaves a giant fissure, with his Psychotic Smirk still firmly in place, oozes badass.
- Full-Name Basis: You will not find anyone in the series who refers to him simply as "Mard", not even Mard Geer himself.
- Game Face: Once he experiences the emotion of "rage", his Psychotic Smirk turns into a terrifying Slasher Smile.
- Good Wings, Evil Wings: Once he enters his Etherious Form, he grows a pair of giant demonic wings on his back. For bonus points, they're both white and black.
- Green Thumb: His curse lets him grow thorns, a monstrous flower creature, and giant rose-shaped bombs. In his Etherious Form, he can create a massive tree branch and use it like a gigantic Battering Ram.
- Humans Are Insects: While other demons purport to share this view of humans, Mard Geer goes the extra mile by punishing Kyôka for amusing herself with her Cold-Blooded Torture of Erza, as it means she is willing to stoop so low as to play with insects.
- I Am Not Left-Handed: He doesn't fight seriously until he puts the Book of E.N.D. down to fight Natsu and the Twin Dragons. From that point on, he reveals he had been doing a lot more than just limiting himself to the use of one hand.
- Impaled with Extreme Prejudice: Gray ultimately beats him by firing an arrow of Devil Slayer ice through his chest. This doesn't kill him, though it does leave him down for the count before Zeref finishes him off.
- Just Toying with Them: He spends the entire fight against Sting and Rogue belittling them as the puny humans he sees them as without even moving in for the kill yet, while they are unable to even scratch him. Sting actually calls him out on this, and demands that Mard Geer fight them seriously.
- Killed Off for Real: Zeref kills him by turning him back into a book and burning it.
- Knight of Cerebus: As the de facto leader of Tartaros and by his own actions on-screen, he is single-handedly responsible for taking this series head-first into previously unseen levels of Darker and Edgier territory.
- Lack of Empathy: Humans are lower than insects to him, and he tortures Kyôka for what he perceives to be too much empathy for humans because she values them as playthings. He also shows no concern for Tartaros's own soldiers when he transforms their fortress into its true form to absorb the heroes, dismissing them as a sacrifice.
- Laser-Guided Karma: He tries to have Minerva killed off after finding her no longer useful to him. Later, he is killed off by Zeref when he finds himself in the same position with the Face plan's failure.
- Long-Haired Pretty Boy: Which he keeps in a ponytail.
- MacGuffin Guardian: He never puts the Book of E.N.D. down until he decides to fight with all he has. Other immortal characters note that he has been holding that book for eons.
- Meaningful Name: A "mard geer" is a type of pole arm originating from the Indian subcontinent. The other part of his name is actually the name of the guild, which is a hint he made it himself and used E.N.D as a pillar for the demons to support it.
- No-Sell: He blocks Sting's White Dragon's Roar using only one finger. Likewise, he blocks Shadow Dragon's Slash with the palm of his hand. When he finally gets angry, he stops holding back and blocks everything Natsu, Sting, and Rogue throw at him, capping off with him catching Sting and Rogue's Holy Shadow Dragon's Flash Fang with both hands to negate it before getting smashed in the back of the head with Natsu's Lightning Flame Dragon's Firing Hammer only to just stumble slightly before batting Natsu away. Only Gray's Ice Demon Slayer Magic and Natsu's Dragon Force consistently hurt him, and the latter didn't leave visible injury.
- Orcus on His Throne: Mard Geer was perfectly content to chill on his throne while Fairy Tail laid siege to Cube and even defeat some of the Nine Demon Gates. He only gets up when he's directly challenged, although he's justified in that he could activate Algeria at any time to swallow them up, so he didn't need to move to deal with them. Lucy escaping it was pointed out as a stroke of very good luck, and once the Celestial Spirit King shows up to trash Cube, people just keep running up to him to keep fighting.
- Person of Mass Destruction: Judging from his equal power with the Celestial Spirit King and his fights with Natsu, Gray, Sting and Rogue, there is little doubt he can use his skills to exterminate entire populations alone.
- Petal Power: He can create rose petals out of curse power that create a giant explosion.
- Psychotic Smirk: Pretty much his default expression. It gets all the more psychotic when he expresses Tranquil Fury.
- Really 700 Years Old: Looks to be in his twenties or early thirties at the latest, yet according to the Celestial Spirit King, it's been centuries since they last saw each other.
- Red Baron: "The Underworld King".
- The Rival: He has one of sorts in the Celestial Spirit King. Noticeably, compared to the dismissive tone he takes with most humans, he has far more respect in his tone and words to the King.
- Satanic Archetype: His Etherious Form, complete with wings, horns, and a tail. According to him, it's why he's called "Underworld King", as he is the "absolute demon".
- Self-Fulfilling Prophecy: He believes that emotions, especially anger, dull one's thoughts and make one take uncharacteristic actions. After his Memento Mori curse fails and Natsu gives him a brief Dragon Force-induced beatdown, he's so furious at Natsu that he fails to notice Gray getting back up and preparing to shoot him until it's too late.
- Slasher Smile: Once he actually gets angry, complete with Wide Eyes and Shrunken Irises.
- Slouch of Villainy: His debut has him doing this while holding E.N.D's Book of Zeref under his arm. He spends the latter half of his fight with the three Dragonslayers settling back onto his throne while unleashing his full power.
- Something About a Rose: He's a hardcore Bishōnen, and his main weapons are a spam of thorny vines. Bonus points for even referring to Cube as "his garden".
- The Stoic: The Celestial Spirit King showing up and bringing down Pluto's Grim didn't even faze him. He even casually greets the Spirit King like an old acquaintance. Of course, that facade cracks to show him being Not So Stoic the longer Fairy Tail simply refuses to die.
- Super-Fun Happy Thing of Doom: Alegria ("Joy" in Spanish) transforms Cube into a raging monster while assimilating both enemy and ally into the walls. According to Silver, the victims are supposed to be happy that they're becoming one with the beast.
- Super Toughness: He straight-up tanks several powerful attacks, including two finishing moves from Natsu that barely even manages to stagger him, with no visible damage afterward. Even Natsu's Dragon Force barely chips at him. They only finally manage a grievous blow when Mard Geer is distracted trying to kill Natsu, allowing Gray to hit him with an Ice Demon Slayer arrow straight through his chest, and even that doesn't kill him. It takes Zeref reverting him to his book form and burning it to finally finish him off.
- Taken for Granite: The Celestial Spirit King's Galaxia Blade turns Mard Geer into stone, though both of them realize it's only a temporary solution that slows him down, since Mard Geer breaks out rather quickly.
- Telepathy: He has the power to hijack Warren's telepathic link to deliver a message to Fairy Tail.
- Third-Person Person: Always refers to himself as "Mard Geer" in Japanese, making him seem even more incredibly arrogant.
- Too Many Belts: On his pants, including on his ankles.
- Tsurime Eyes: And they're squinty.
- Underestimating Badassery: He is rather shocked to see Natsu isn't as much of a pushover as Sting and Rogue had been. Then again, he isn't too impressed from his very brief round with Erza, either, so up until this point, he didn't have much of a reason to expect a whole lot from any of the humans.
- Unholy Nuke: His ultimate curse, "Memento Mori". Anything caught in its blast radius vanishes entirely.
- Villainous Breakdown: When his ultimate curse "Memento Mori" is nullified by Gray, he becomes enraged; even when he told Natsu and the Twin Dragons that he was feeling fury, he still had his Psychotic Smirk, but not at this point. After taking a beating from Natsu's Dragon Force, he completely loses what vestiges of sanity he had left. And just when he thinks he's about to live long enough to see his Face plan come to fruition, the dragons return and rip his remaining hopes to shreds. When Zeref finds him, he's a trembling, fearful wreck of a once proud demon.
- Worthy Opponent: He is unfailingly polite to the Celestial Spirit King, and even compliments him mid-combat.
- You Have Failed Me: Not only does his plan to reawaken E.N.D. completely fall through, but his so-called ultimate curse doesn't even have any effect on a demonized Gray. It's for these reasons that Zeref decides he never stood a chance to fulfill his purpose and kills him.
- You Won't Like Me When I'm Angry: After he starts taking Natsu more seriously and is faced with three Dragon Slayers in combat, he shows us that he's Not So Stoic after all and unleashes an unsettling Slasher Smile for the history books.
Nine Demon Gates
The strongest demons of Tartaros besides E.N.D and Mard Geer make up the Nine Demon Gates. Each member holds a unique kind of curse or magical power that gives each of them the destructive power of an entire army.
- The Dreaded: They are widely respected by their subordinates, as well as feared even by other dark guilds across the continent for a valid reason. Jackal alone has proved able to exterminate most of the members of the Magic Council and raze the entire base with ease, not to mention the scale and strength of Silver's power that allows him just as easily to freeze an entire village of giants, including their Eternal Flame, almost by mistake.
- Keigo: Seilah and Franmalth use this by default, but the former drops it in her Etherious Form (she also starts using "ware" instead of "watashi"), and the latter dips into crude language when he's angry.
- Knight of Cerebus: Compared to previous Quirky Miniboss Squad characters in the series, these guys can be downright terrifying, and all of them have kicked Fairy Tail members' asses at least once.
- One-Man Army: According to Franmalth, Zeref created them to match the strength of an entire country's military force.
- One-Winged Angel: A good number of them have an Etherious Form in where they take on more demonic appearances and drastically boost the effects of their curse powers. The only ones who don't have (or at least never resort to using) such forms are Franmalth (who instead uses the strongest soul in his possession to transform for a power-up), Keyes, and Silver (who isn't a demon to begin with, though Kyôka's brief comments and the fact Gray is able to tap into his Demon Slayer Magic to manifest black markings over his body and greater power implies Silver has a similar power-up state).
- Quirky Miniboss Squad: They are on a much different level to other squads being rather scary in comparison.
- Red Baron: All of them except Jackal had a certain kind of nickname.
- Tragic Dream: In a sense, their desire to be reunited with Zeref. Only Mard Geer and E.N.D. seem to be aware of the true reason why Zeref created them, meaning that even if they had won, they would never get the Happily Ever After they want with their creator.
- Two Girls to a Team: Kyôka and Seilah are the only female members of the Demon Gates.
- Undying Loyalty: All of them hold this for Zeref, believing it to be their life's goal to reunite with him. Only Silver, a reanimated human and pawn of the guild, has no such notions.
- Unwitting Pawn: Unlike Mard Geer, none of them seem to realize that Zeref created them as a means of killing himself. Thus, Mard Geer easily manipulates them into helping him form the guild to further his own plans of killing Zeref himself, leading them under the false pretense that they will finally be able to meet their creator.
Voiced by: Ai Kayano (Japanese), Janelle Lutz (English)
The leader of the Nine Demon Gates, and a devout fanatic of Zeref who finds no greater pleasure than torturing humans. She can use her Strength Enhancement curse to enhance any target's strength and physical sensations, particularly their sense of pain, well beyond their natural limits.
- Absolute Cleavage: Virtually her entire chest is bare. Taken up to eleven with her second outfit, which is full-blown Vapor Wear. And then she goes into her Etherious Form, which sees her wearing even less.
- Agony Beam: She can heighten her victims' sense of pain, making it so that even the softest puff of air can cause total agony. It's bad enough to break Erza, who could earlier withstand the activation of her Second Origin as if it were nothing while everyone else writhed and screamed in anguish.
- The Ace: Next to Mard Geer, she is the only one who is capable of using both curses and magic. She is also the only one of her companions who is able to use more than one curse (not to mention that, like Franmalth, she is able to absorb new kinds of powers from others). It is not by chance that she is considered the strongest of the nine.
- Alto Villainess: Both Ai Kayano and Janelle Lutz provide a deep, creepy voice for Kyôka, who's an efficient fighter and Torture Technician.
- Antagonist Abilities: The ability to increase the sense of pain of own enemies to infinitely is a power so overwhelmingly powerful to which call it one of the most coveted awards in the Superpower Lottery is pure euphemism.
- Back from the Dead: Downplayed. A Historia of her is created by Neinhart in the Alvarez Empire arc, and she gangs up on Erza together with Azuma and Ikaruga.
- The Baroness: Her sadistic extermination of Succubus Eye causes Minerva, the previous queen of this trope, to quiver with fear. She also exhibits several other Dominatrix tendencies such as her Cold-Blooded Torture of Erza and her implications in bed with Seilah.
- Bullying a Dragon: Erza doesn't take kindly to all that Cold-Blooded Torture she subjected her to.
- Character Death: She gets stabbed by Minerva with Erza's sword in a vain attempt to stop her from activating Face, which would have killed her anyway.
- Clothing Damage: As a result of Mard Geer's torture, her Leotard of Power snaps off and her helmet and mask cracks, leaving her in a Stripperific outfit.
- Cold-Blooded Torture: She does this to Erza, ranging from flogging to Electric Torture, all amplified by her Agony Beam. She later gets this turned on her when Mard Geer ties her up with thorny vines as punishment for taking pleasure in torturing Erza, seeing this as a sign that she, in a warped way, actually likes humans.
- Cool Mask: She wears a Gem-Encrusted helmet, which eventually cracks off during her Cold-Blooded Torture at the hands of Mard Geer.
- Cute Monster Girl: As one of the more human-looking demons, with only her bird-like hands and feet marking her as such, she proves to be quite attractive once her mask comes off.
- Dark Action Girl: She's able to match Erza, the series' prime example of an Action Girl, blow for blow.
- Death Is the Only Option: She fuses herself with Face's activation lacrima, thus using it to accelerate Face's activation due to Acnologia's unfortunately-timed arrival. This, however, would ultimately result in her death even if she survived Erza's battle.
- Did They or Didn't They?: She tells Seilah she's going to "take care of her", and in a later scene, Seilah is shown in bed, with her Minidress of Power replaced with a Modesty Bedsheet, smiling.
- The Dragon: To Mard Geer (acting as Dragon-in-Chief to E.N.D.), since she's the leader of Tartaros' elite squad.
- Even Evil Has Loved Ones: As horrifically sadistic as she is, her affection for Seilah is genuine. When Seilah lies beaten and all her other comrades have fallen, she tenderly absorbs Seilah's soul and curse power and promises to avenge her.
- Even Evil Has Standards: Mard Geer trapping all of their soldiers in Alegria along with Fairy Tail is too much even for her, which is ironic given how she did almost the exact same thing to Succubus Eye.
- For the Evulz: Kyôka seems happy that Erza can't or won't tell her anything about Jellal since it means she can keep torturing her. To put it further, she later states outright that she could have just used Seilah's power to pull the information out of Erza, but didn't want to because there's no fun in that.
- Gathering Steam: In her Etherious Form, she not only gains a general power boost, but her Curse is enhanced to the point she can gradually boost her already considerable power ad infinitum. The only reason this doesn't become a problem is because she's already fused herself to Face's activation lacrima to speed up the countdown so she doesn't have long to live anyways, instead having her serve as a Threshold Guardian the heroes can't avoid fighting.
- Harping on About Harpies: Her Cool Mask looks vaguely like a bird's head, her hair resembles a pair of wings, and she has talons for hands and feet. Her Etherious Form also adds feathers on her back and horns.
- Hartman Hips: She has very shapely hips and thighs, and doesn't mind wearing clothing that shows them off. She also has big breasts, but given that almost all girls in this verse have that, hers don't stand out nearly as much in comparison.
- Horned Humanoid: She gains two long horns up the sides of her head in her Etherious Form.
- Impaled with Extreme Prejudice: Minerva runs her through with Erza's sword to finish her off, though she only smiles as Face's activation still succeeds.
- Interplay of Sex and Violence: Her extremely suggestive battle dialogue with Erza only solidifies her Psycho Lesbian image.
- Laser-Guided Karma: Captures and tortures Erza to obtain information while accusing her of things that are patently untrue. Mard Geer does much the same to her when she reports to him.
- Leotard of Power: And a very revealing one at that. It's later replaced by an even more Stripperific outfit, complete with Bare Your Midriff and even more Absolute Cleavage, after her old outfit is broken off by Mard Geer's torture.
- Magic Enhancement: Kyôka uses a brutal version of this. If the people she casts her enhancement curse on have the right fortitude, they'll become stronger than they can imagine. If they aren't, they're turned into paper dolls. She can also increase her own power gradually and ad infinitum while in her Etherious Form.
- Meaningful Name: Her name literally means "to strengthen" in Japanese, which is her curse power.
- Ms. Fanservice: A candidate for the best villainous example in the series, with her virtually non-existent clothing and frequent butt-shots making all previous examples look like The Ingenue in comparison.
- No-Sell: Being slammed through Cube so hard she comes out the other side at the point of a giant lance does nothing to her.
- Not Afraid to Die: According to what Mard Geer told her, all demons return to Zeref once their duty in life has been fulfilled, so she yearns for death to reunite with him. However, she does hesitate momentarily when Mard Geer orders her to merge with Face's control lacrima to speed up the detonation, which would kill her.
- Pointy Ears: They only become visible when her helmet cracks off.
- Power Incontinence: When using her enhancement curse on Erza in her Etherious Form, she loses control and casts it on all the battle's onlookers as well, though not to the same intensity.
- Psycho Lesbian: She's all but stated to be in a romantic relationship with Seilah. She also gets quite a bit too suggestive for comfort while she's torturing Erza.
- Purple Is Powerful: Her eyes and outfit are purple, and she stands as the most powerful member of the Nine Demon Gates who comes close to killing Erza on more than one occasion.
- Red Baron: "Goddess of the Slave Planet Kyoka".
- Sadist: She takes absolute pleasure in torturing humans, particularly Erza. Mard Geer actually disapproves of this, since it means that Kyôka doesn't truly consider them as lower than insects like her kind is supposed to.
- Senseless Sacrifice: She forfeits her own life in order to activate Face, thereby unsealing the Book of E.N.D. and taking out Acnologia in one fell swoop...only for that to be completely rendered moot by the timely arrival of the dragons, who destroy all of the Face bombs across the continent. On top of that, it turns out that Face was a completely unnecessary step in awakening E.N.D. to begin with.
- Shut Up, Kirk!: Dismisses Erza's criticism of the demons' Blind Obedience to Zeref without even considering thinking for themselves, stating that a human "could never understand."
- Slasher Smile: She flashes one to show how much she enjoys testing (i.e., torturing) potential recruits and prisoners of war.
- Statuesque Stunner: The scenes of her torturing Erza show that she's a head taller.
- Stripperific: About the only part of her body still left to the imagination is her face before her mask is destroyed.
- Third-Person Person: An odd case in Japanese where she refers to herself with the pronoun "konata", which is usually used to describe "this/that person", and is translated as "this one" in the official English manga. Averted in the English dub, however.
- Thong of Shielding: All three outfits she goes through seem tailored to reveal as much of her butt as possible.
- To the Pain: Once she has Erza on her knees during their fight, she removes each of her senses one by one, minus her sense of pain, which has been amplified so much that even the softest breeze causes her to writhe in agony. She then declares that Erza will spend the rest of her life as Mard Geer's puppet in this hellish state. In a Badass Boast, Erza scoffs at the idea of this being called "pain" and continues the fight anyway.
- Undying Loyalty: To Zeref, but for a different reason than any of the previous Zeref fanatics in the series. As a demon, she and the other demons see Zeref, their creator, almost as a father figure. Kyôka in particular claims that everything Tartaros does is for him alone, and even says that they are working so that they can curry his favor enough to rejoin him at his side.
- Villainous Breakdown: When Erza suddenly starts overpowering her despite her strength growing every second while Erza has no way to sense the world other than a maximized sense of pain, she drops all attempts to flirt with Erza in her own sadistic way, and begins attacking out of pure rage.
- Wolverine Claws: Her fingers can extend into long, whiplike appendages. They're also pointed at the end, perfect for flogging and impalement.
- You Gotta Have Blue Hair: Her hair is green.

Gray's dead father, who was reanimated by Keyes and inducted into Tartaros under the masquerade of Deliora, the Etherious who killed him. Fueled by hatred towards Zeref's demons for taking his family from him, Silver became a powerful Ice Demon Slayer with the express purpose of destroying Tartaros from the inside. Upon discovering his son's survival, however, Silver loses his will to live and changes his objective to making sure Gray puts him out of his misery, no matter what it takes.
- Affably Evil: He's a pretty nice guy... just don't piss him off, or he'll freeze you solid before you can blink.
- And Your Little Dog, Too!: During his fight with Gray, Silver promises that once he's done with him, he'd go after Lyon next, and after that, the rest of Fairy Tail. The fact that he was bluffing didn't exactly make this threat any better, which Silver himself admits.
- Arch-Enemy: He appears to be Gray's, claiming to have learned Ice Demon Slayer magic to fight him. Subverted when he reveals that claiming to be Deliora was a bluff to get Gray to kill him.
- Badass Baritone: Brought to you by Kenjiro Tsuda and Matthew Mercer.
- Badass Beard: More like Badass Five O'Clock Shadow, but close enough.
- Badass Cape: Because cool armor just isn't enough for this guy.
- Berserk Button: Mentioning Gray's "disgusting name" in front of him causes his cordial nature to vanish. It's actually an act because he knew Mard Geer was watching.
- Chekhov's Gunman: Subverted. He claims to be Deliora; the demon responsible for killing Gray's parents, Ur using Iced Shell, and just about everything else wrong with Gray's life; possessing the body of Silver Fullbuster, Gray's father. In truth, he's actually Silver's corpse reanimated by Keyes.
- Curb-Stomp Battle: This is pretty much what he does.
- He single-handedly froze the spirit of a fire dragon and an entire village of giants with what appears to be minimal effort.
- He froze Natsu solid with one wave of his hand. Natsu became another of Tartaros' prisoners for his trouble.
- His fight with Gray consisted of him nullifying everything Gray tried. Ice Make spells? He shrugs them off or flat-out eats them. Converting the rubble around the battlefield into ammunition to fire at him with ice cannons? Freeze over the battlefield to deny him that advantage. Gray channeling and hitting him with his own Demon Slaying ice now coating the battlefield? It only does minor damage because he's not actually a demon in the first place. It's ultimately revealed he only lost because he wanted Gray to win.
- Death Seeker: After learning his son survived Deliora's attack, he realizes all of the terrible acts he'd committed and wishes to be put out of his misery. To that end, he poses as Deliora to get Gray angry enough to kill him; even when Gray figures the truth out, Silver resorts to pointing himself out as an enemy of Fairy Tail to justify why he needs to die. When Gray still can't bring himself to do it, he telepathically requests Juvia do it instead.
- Demonic Possession: Subverted; he claimed he was Deliora possessing Silver's body. See Death Seeker as to why.
- Demon Slaying: Demon Slayer magic. It hits for massive damage against demons, such as those from the Books of Zeref. It's no slouch against dragon spirits, either.
- Did You Just Punch Out Cthulhu??: He ended up doing this to Atlas Flame's spirit to a degree on the assumption he was a demon, even though the being he attacked was a dragon. Normally this wouldn't apply to a demon, but it turns out he's simply human.
- Even Evil Has Loved Ones: He is first shown paying respects to a grave, later revealed to belong to his wife, Gray's mother Mika and Gray himself. Notably, Gray's name on the marker has be crossed out.
- Evil All Along: He claims that he's Deliora, which turns out to be a lie. However, Silver still fully admits that he did some pretty awful things as a member of Tartaros, and that calling him 'good' is still a stretch.
- Evil Is Hammy: During The Reveal, he shows us that he can really be this when he's in full villain mode. He delivered one Kick the Dog after another to Gray, all while sporting Slasher Smiles and Nightmare Faces that would have given Jackal chills. Of course, he was actually just playing up the image to get Gray mad enough.
- Family Theme Naming: Silver and Gray are different shades of the same color, duh.
- Fangs Are Evil: His canines become quite prominent after The Reveal. He had them all along, being a Demon Slayer, but they weren't really noticeable until he's sporting Slasher Smiles and Evil Laughter.
- Good Scars, Evil Scars: He has a noticeable scar across the upper-left side of his face. It's likely that this scar is from the wound that killed him during Deliora's rampage.
- Handsome Lech: He shamelessly flirts with Kyôka. She seems more amused by it than anything.
- Harmless Freezing: Zigzagged. His Ice Demon Slayer Magic is a Kryptonite Factor for demons, and Atlas Flame's spirit had lost most of its memories and was on the verge of fading after being trapped in the ice for so long though The Reveal about Acnologia draining the souls of dragons 400 years ago implies he was already on his last legs long before that, but the giants themselves were completely unharmed after being thawed out. The same thing happened to Natsu after he had the misfortune of pressing Silver's Berserk Button, appearing just fine after being completely encased in ice (though the later reveal about him not really being evil implies he did it to keep up appearances to the guild and held back), so his frozen non-demon victims seem to be completely unharmed after thawing out.
- Heel Realization: Despite becoming a corpse, he was more than content to take down the demons of Zeref on the inside until seeing Gray in the GMG.
- Hunter of His Own Kind: Despite being in a genocidal guild full of demons, he actually hunts demons and apparently consumes their souls. When he interrupts Franmalth's battle with Natsu, the former looks absolutely terrified of him. That said, Atlas Flame actually referred to him as a human when describing the person who froze the village. Juvia lampshades how weird it is for a demon who knows Demon Slaying magic to join a guild full of demons. Keyes suggests that it was possible that Mard Geer accepted Silver into the Nine Demon Gates in order to act as a deterrent to keep the other Gates in line; but admitted that it ultimately didn't matter, since Silver was more than powerful enough to qualify for the position regardless of what kind of magic he used. Subverted when it's revealed that Silver isn't really a demon.
- An Ice Person: A proficient user in Ice Demon Slayer Magic and one of the most powerful ice user we have seen in the series; his Ice Demon Slayer powers allow him to flash-freeze an entire village in an instant. Short of Invel Yura, one of the Spriggan Twelve who's head and shoulders above both of them, he may very well be the only ice mage in the series to rival, if not surpass Ur.
- It's Personal: He appears to hold a serious grudge against Gray, which seems quite justified when he tells Gray he's actually Deliora, and thus has it out for all of Ur's students. This, however, is a lie to get Gray to kill him; it's actually personal against demons in general, as he's been on a covert Roaring Rampage of Revenge against them ever since he thought Gray died.
- Kick the Dog: He tells Gray he's Deliora in possession of his dad's body and gloats about wanting to kill him. This is all part of his gambit to get Gray to kill him, and he hates himself for it.
- Light Is Not Good: He is a Demon Slayer, also known as an exorcist wizard, whose magic is designed to vanquish demons. He's also a member of a dark guild made up almost entirely of demons whose stated goal is to Kill All Humans. It later turns out that he was Good All Along, as Silver learned this magic and joined the guild with the noble intention of destroying it from within, though he himself states he still did some pretty terrible things as a member of Tarrtaros to keep up appearances.
- Luke, I Am Your Father: Double-subverted. Gray immediately recognizes him as his father, Silver Fullbuster, but dismisses the notion because he was killed by Deliora. In response, Silver claims that he is Deliora, who possessed Silver's corpse to use as a human vessel. Not long after Gray defeats him, he clues in that Silver was faking being Deliora.
- Noble Demon: Despite being Tartaros' Token Good Teammate he does seem to be mostly loyal to the dark guild as a whole, as shown when he finally joins in the fight against Fairy Tail. Of course, that could just be because he was finally able to confront Gray. Seemingly subverted when he reveals he's actually Deliora, making him just as bad as his allies, but then double subverted as he was lying about being Deliora, though he fully admits that he did some pretty awful things as a member of Tartaros.
- No-Sell: Being an Ice Demon Slayer, he can freely eat any form of ice magic and is otherwise hardly affected by it, which lets him smack Gray around without a care in the world. Even when Gray reverses his own ice on him, it only does minor damage despite its anti-demon properties, and that's because he's not a demon. Gray is forced to convert nearby stone rubble into ammunition for various ice cannons to do any actual damage, and ultimately is only able to put him out of the fight by throwing a large steel ball through Silver's chest.
- The Only One Allowed to Defeat You: He refuses to let any of the other Nine Gates try to fight Gray, grabbing the kid and promptly getting both of them far away from the battlefield everyone else is on. Although it turns out it wasn't so much because he wanted to be the one to defeat Gray as he wanted Gray to beat him so he could pass on his Demon Slayer Magic and the best chance Gray would have of taking on Mard Geer.
- Pet the Dog: After Natsu and Lisanna are subjected to a Shameful Strip and thrown into a cell together, he visits their cell and gives Lisanna a blanket to cover herself with.
- Red Baron: "Absolute Zerø Silver."
- The Reveal: Threefold: He's Silver Fullbuster, Gray's dad. Or rather, he's actually Deliora in possession of his body. Then it's revealed that he really is Gray's dad, or rather his reanimated corpse controlled by Keyes.
- Single-Stroke Battle: Freezes Natsu solid with one wave of his hand.
- Spanner in the Works: He let Happy escape after capturing Natsu, leaking the nature of their base, and letting Fairy Tail pinpoint their exact location. He also may have dropped the sword for Natsu to use to escape his cell. Franmalth actually comments on this.
- Survivor Guilt: His motivation for a covert Roaring Rampage of Revenge against Zeref's demons, up until he realized Gray was alive, resulting in a Heel Realization.
- Token Good Teammate: He hunts demons, and when the others all talk about their plan and how the current destruction they've caused is just the start, he's noticeably silent and going by his expression, he's less than thrilled. While he did freeze the Sun Village, he did it because he thought the Eternal Flame was a demon, and actually thanks Natsu for thawing it out.
- Torso with a View: Gray beats him by launching a steel ball through his chest, leaving a large hole.
- Uncanny Family Resemblance: If your first thought upon looking at his picture above was "Wow, that guy looks like he could be Gray's dad!" you're right. It's especially noticeable in Gray's Avatar get-up.
- Voluntary Shapeshifting: Kyôka comments on him showing up in his "human form", implying his current, humanoid appearance isn't his true one. It's later subverted; he has no demon form, as he's not a demon. That said, given Gray is able to summon black markings when overusing his Demon Slayer Magic, it implies Silver has a similar ability at his disposal.
- Walking Spoiler: And not just for the reason fans thought.
- Weaksauce Weakness: Averted. When Gray uses his own anti-demon magic to blast him, he tanks it and suffers only minor wounds because he's not a demon; he's the reanimated corpse of a human.
- Well-Intentioned Extremist: Ultimately revealed to be this. While he intended to destroy Tartaros from the inside, including E.N.D, he still assisted Tartaros in some of their more horrible actions like the Face Project.
- Wham Line: "My name is Deliora! Surely you haven't forgotten me, have you, Gray!?"
- "You're right I was once your dad, but I'm no longer a human or a demon...I am a corpse."

A psychotic demon whose explosive curse can turn anything he touches into a bomb. True to his name, his actual form is a giant canine monster.
- Ax-Crazy: He's not much different from Grimoire Heart's Zancrow in this regard, cackling at the sight of the destruction and mayhem he causes.
- Clipped-Wing Angel: Once Natsu figures out how to eat Jackal's explosions without getting hurt, Jackal resorts to his Etherious Form to take him down through brute force. Too bad for him, Natsu is more than used to dealing with physical fighters.
- Collision Damage: A particularly nasty side-effect of his powers is that anything that touches his skin directly spontaneously explodes. Natsu learns this the hard way when he gives Jackal a No-Holds-Barred Beatdown.
- Death Is Cheap: Unlike Tempester, who loses his memories whenever he is resurrected, Jackal doesn't suffer any negative consequences whatsoever, except that he just doesn't learn from his previous experience.
- Even Evil Has Standards: Mocks his target, Michello, for running away out of fear for his own life, leaving his granddaughter behind.
- Evil Laugh: "Kuhahaha!"
- Explaining Your Power to the Enemy: He has a bad case of this, but he's confident he can get away with it since even touching him can cause his enemy to explode. Unfortunately for him, this lets Natsu figure out a trick to avoiding the damage.
- Fangs Are Evil: Goes with his Little Bit Beastly appearance. His teeth look like that of a canine.
- For the Evulz: Outright states to Lucy that he's not really looking to gain anything, and that he just sees humans as playthings.
- Having a Blast: His curse allows him to blow up anything he sees and touches.
- Hellish Pupils: His eyes make him look almost catlike in appearance, which is odd considering that jackals are canines.
- Kansai Regional Accent: Has a pretty thick accent in the Japanese version.
- Killed Off for Real: If getting blasted by Lucy's Urano Metoria once Hell's Core was taken out of commission didn't kill him and assuming Mirajane didn't absorb him into her Satan Soul: Algeria, it was certainly Zeref's death at the end of the series.
- Law of Disproportionate Response: Torafuzar telling him to stop toying with Lucy and just kill her? He gets a little angry but nothing comes out of it. Lummy supporting the torture and suggesting blowing up Lucy's breasts? He blows her to pieces.
- Lightning Bruiser: His Etherious Form is bigger, yes, but it is also swift and packs a wallop.
- Little Bit Beastly: His "human" form has pointed ears, a furry yellow tail, and a nose just like an actual jackal.
- Mad Bomber: Aside from blowing up the Magic Council's headquarters, he destroys random buildings during his fight with Natsu, Lucy, and Wendy pretty much because he could.
- Offing the Annoyance: He expresses great annoyance towards Lummy's lack of personal space the moment he comes out of Hell's Core. Eventually, he just decides to blow her up.
- Our Werewolves Are Different: Jackal's Etherious Form is a giant lycanthrope, and he can assume it through Voluntary Shapeshifting.
- Peek-a-Bangs: His hair covers an entire half of his face.
- Person of Mass Destruction: His curse causes spontaneous explosions of all sizes and intensities. He can kill dozens of people and demolish an entire building effortlessly.
- Revenge by Proxy: With Natsu and Happy falling victim to Alegria, he decides he wants to take out his revenge on Lucy instead.
- Sadistic Choice: He just loves giving these to his victims. First, he gives Michello a choice between both he and his granddaughter dying, or him giving him—and by extension, Tartaros—the location of a certain MacGuffin he's looking for, in which case he would live...but his granddaughter would still die. Later, he presents Lucy with a choice between saving Michello or a Pregnant Hostage. Lucy is spared from making this choice by Natsu.
- Scarf of Asskicking: His scarf is a staple of his appearance, keeping it even when he enters his Etherious Form. He gets an even longer one after being resurrected by Lummy.
- Slasher Smile: Massacres countless innocents, blows up a village, and forces more than one Sadistic Choice on others while sporting one of these.
- The Sociopath: He enjoys blowing things up, and he impulsively torments his opponents at any opportunity, despite being criticized by his comrades for wasting time. Said comrades are threatened with an explosive death simply for not allowing him to indulge himself.
- Taking You with Me: As with Tempester, once his defeat seems inevitable, he tries to blow up the town with Natsu's group still in it. It's thwarted when Happy flies him above the city.
- Too Dumb to Live: He refuses to listen to Torafuzar's advice to kill Lucy quickly when she appears to be beaten. Lucy gets a Power-Up and blasts him with Urano Metoria shortly after.
- Villain Ball: He's so focused on trying to torture Lucy for his previous loss instead of outright killing her that it gives her time to summon Aquarius, who sacrifices herself to summon the Spirit King and destroy Tartaros' home base.
- Villainous Breakdown: When he finds that a "puny human" can actually go toe to toe with him. Even moreso when his Taking You with Me plan fails.
- Would Hit a Girl: He threatens the lives of Lucy, Michello's granddaughter, and a Pregnant Hostage. And that's to say nothing of how he later kills Lummy just for annoying him, and later blowing up one of Lucy's legs.

A beast-like demon who can call forth natural disasters and calamities with a simple flick of his tongue. He has died and come back more often than any of his fellow Etherious, and as a side effect, his memory is so foggy that he can hardly recall his own name.
- Adaptational Badass: The anime version of the Tartaros arc gives him much more variety in his curses along with a second battle with Laxus. While Laxus looks impressive by standing his ground while poisoned Tempester proves to be no pushover either.
- Badass Boast: Gives on to the thunder tribe as he prepares to kill his target."I have no name I herald calamity for humanity. The gate to the underworld is open! We are delivering mankind's rightful punishment! Fall to hell!"
- Beard of Evil: Sports a chin curtain in his first body and in his Etherious form.
- Beast Man: His original appearance and Etherious form is a hulking man with a lion-like face and mane. Lummy doesn't like this, so when he needs to be resurrected, she turns him into a full-on Dark-Skinned Blonde Bishōnen in his base form.
- Bilingual Bonus: The "Tempesta" name is Catalan and Italian for storm.
- Bishōnen: His second body is this in spades, as invoked by Lummy.
- Blow You Away: While he has many calamities at his disposal and is happy to use them, wind based ones seem to be his favorite, whether it's summoning tornadoes or surrounding his lower body to move around faster or coating his fists with them to boost his punching power.
- Bond Villain Stupidity: In the anime, when he cornered Laxus and Gajeel on, he, rather than just killing them, explains his title of 'Immortal' and even tells how they can defeat him, apparently confident that in their current weakened states they won't be able to muster enough power to do the job. In fairness, he's right...but then Laxus reveals that the various puddles of Torafuzar's Tenchi Kaimei all over the battlefield have been electrified over the course of their battle, and he then proceeds to unleash one final Lightning Dragon's Roar at the ground that uses the black water as a conductor and amplifier to unleash the required finishing blow.
- The Coats Are Off: He rips his tattered coat to shreds after Laxus gets the drop on him.
- Curb-Stomp Battle: The Raijin Tribe barely have time to attack him when he makes his appearance, and he blows them away without any trouble. This is reversed on him when Laxus beats him without even trying, though Round Two in the anime puts them both on more equal footing due to Laxus still being weakened and Tempester being in his Etherious form. Then he fought Gray which lead to a One-Hit Kill for Tempester.
- Dark-Skinned Blond: In his second body.
- Did Not See That Coming:
- He doesn't expect someone from Fairy Tail—or indeed, any human—to be so strong, and thus doesn't fight as seriously against Laxus. He's a bit wiser the second time around, holding his own against Natsu and co. for much longer.
- He also was not expecting Gray to use the weakness of demons freezing his curse and then killing him with just one move.
- He was sure as hell not expecting Laxus to show up in the anime version getting his rematch with Tempester.
- Dies Differently in Adaptation: In the manga, he fights Gray and gets killed. In the anime, he fights Laxus and after his defeat, kills himself to turn himself into toxic mist and try to kill the heroes, only for Gray for freeze the mist.
- Dishing Out Dirt: As seen in the anime he can also create sinkholes from the dirt with his calamity-based curse.
- Elemental Powers: His curse can make natural disasters from cyclones, downpours, firestorms, lightning strikes, and rockslides.
- Elemental Punch: One of his favorite melee moves is to coat his fist in wind to enhance its striking power.
- Explaining Your Powers to the Enemy: Averted, given how little Tempesta spoke (though he does explain what the Devil Particles do), and it doesn't help that his curse was one of the ones that never got named, leaving the extent of his powers vague. Later subverted as he explains the basics of his immortal body to Gajeel and Laxus which leads to his death in the anime.
- Flat Character: In the manga, he doesn't get much more characterization than the condescending view of humanity shared by the rest of his guild; even his powers remained poorly defined. He does get more of a chance to shine in the anime.
- Idiot Hair: In his second body.
- Immortality: In the anime Tempester reveals he has been granted a large amount of curse energy through a connection with Mard Geer. Essentially he can revive himself unless he is brought down with a single powerful blow. This explains the reason he got his nickname the "Immortal" of Tartaros.
- In the Hood: He wears a hood that covers part of his face during his introduction.
- Killed Off for Real: Gray kills him with his new Ice Demon Slayer Magic and his blood is used to make an antidote for the poison. The anime version has Laxus take Gray's place, though Gray steps in to make sure Tempester can't go for one last hurrah.
- Laser-Guided Amnesia: He says that he's been killed and resurrected so many times that he loses his memory every time his body reforms at Tartaros' HQ, to the point that he doesn't even remember or care about his own name. This seems to be a production defect, though, since other demons can remember their past selves perfectly fine.
- Little Bit Beastly: He seems to have fur and a animal like face, though what kind is unknown due to his Hood. Seems to be a bit Lion but its hard to tell.
- Mage Killer: Once defeated, he explodes into a cloud of toxic mist called Devil Particles that are deadly to ordinary people, particularly wizards.
- Meaningful Name: He's the guy throwing around magical tempests.
- Mind over Matter: In the anime his curse allows him to lift rocks into the air to attack people.
- No-Sell: He takes a direct hit from several members of the Raijin Tribe, and barely even flinches. He can even withstand hits from Laxus in their rematch, and still come back hence his immortality.
- Person of Mass Destruction: With a simple blow, he whips up a huge tornado that levels Yajima's restaurant. His Devil Particles are also eerily reminiscent of a real-life chemical weapons attack, body count and collateral damage included.
- Playing with Fire: Not only can he use fire in his calamity curse Tempester can belch it like Natsu does or cover himself in flames. Laxus calls it "lukewarm" flames.
- The Red Baron: Tempester "The Immortal".
- Rule of Sexy: In-universe example; Lummy says this was her reason behind turning him into a drop-dead gorgeous Dark-Skinned Blonde (while shamelessly fawning over him).
- Taking You with Me:
- Subverted with his final attack. At first it looks like he's killing himself to take out Laxus, the Raijin Tribe, and Yajima, but then he reveals that he's perfectly alive and just needs to return to HQ to reform himself.
- In the anime he tries this again when his body is close to death after Laxus' final attack, noting that with Hell's Core's destruction this will be his final move regardless, but Gray freezes the particles.
- The Quiet One: He hardly seems to speak, and when he does, his sentences consist of about three or four words total.
- Villainous Legacy: Even though he was defeated, the particles that Laxus absorbed because of his explosion still affects him one year later.
- White Hair, Black Heart: His second body.
- The Worf Effect: Gets beaten in less than half a chapter twice, first by Laxus, then by Gray, with his newly acquired Ice Demon Slayer Magic.

A she-demon with a penchant for literature who treats everything around her as if it were a story. Calm yet ruthless, she exerts total control over the bodies and actions of humans unfortunate enough to fall within her Macro curse.
- Badass Bookworm: Enjoys good stories, though she finds the stories written by humans boring.
- The Berserker: She has no conscious control of her One-Winged Angel form, replacing her usual demeanor with bestial screaming and shrieking.
- Chekhov's Skill: She states that her Macro curse can control dead bodies, though not as effectively as Keyes's Necromancy. After Keyes's death, she controls the dead Council chairman to activate Face.
- Curb-Stomp Battle: She gives Mirajane a hard enough time as it is, but once she whips out her One-Winged Angel form, she blows Mirajane's then-ultimate Sitri form away.
- Cute Monster Girl: Discounting Silver, Seilah is the most human-looking demon of the group, looking like a pretty young woman with horns.
- Death Glare: Gives one to the Strauss sisters as she tells Lisanna that she'll kill Mirajane to make up for the failure and humiliation Elfman caused her.
- Demonic Possession: Inverted. By the events of the Alvarez Empire arc, Mirajane has learned to take over Seilah's body with her Satan Soul, which she does in order to save her life.
- Does Not Like Shoes: Her Zettai Ryouiki are the only thing on her feet besides nail polish.
- Eerie Pale-Skinned Brunette: Black hair, but close enough with her eerily calm personality.

- Femme Fatalons: Complete with nail polish. In her One-Winged Angel form, they become sharp enough to slice through flesh.
- Full-Frontal Assault: Going One-Winged Angel tears off her clothing, except (initially) her detached sleeves. Little attention is drawn to her breasts, however.
- Fur and Loathing: Part of her Minidress of Power appears to have been made from something similar to leopard skin.
- Glowing Eyes of Doom: Her Etherious Form has these, leaving a trail of light whenever her eyes move around.
- Hero Killer: Mirajane is one of the best wizards in Fairy Tail's roster, on par with Erza. Seilah destroys her while barely taking a scratch, and would have killed her were it not for Mirajane invoking Elfman's Dynamic Entry.
- Hoist by His Own Petard: Mirajane uses Seilah's own curse to puppeteer Elfman into pulling a Big Damn Heroes to strike Seilah down.
- Horned Humanoid: Aside from the markings, this is one of the only physical features she has that doesn't look entirely human.
- Impossibly-Low Neckline: It's a mystery how her Minidress of Power stays up.
- Laser-Guided Karma: Her defeat comes at the hands of Elfman, whom she'd previously used to try and destroy Fairy Tail.
- Manipulative Bitch: She uses Elfman's love for Lisanna to act against his own guild by forcing him to strangle his own sister, pressuring him into making a Deal with the Devil to save her life.
- Morality Pet: Kyôka might be an extreme Sadist, but Seilah manages to bring her warmest side to the surface, and is the only one Kyôka cares about. The anime even adds a scene where Kyôka remembers Seilah's smile before Face inevitably drains all her life.
- Necessary Drawback: When she goes One-Winged Angel, she focuses all her power on attack, weakening her control over others.
- Night of the Living Mooks: Played with. She openly admits that corpses are harder for her to control than living People Puppets, as she demonstrates with the corpse of a freshly-slain ex-Council member.
- No-Sell: On the giving and receiving end of this; Mirajane can't use Takeover on her and she can't use Macro on Mirajane, forcing the two to decide their battle on strength alone. It's later dropped entirely when Mirajane manages to absorb a fraction of her powers, which leads to her defeat. Mirajane takes it a step further when she is able to fully take over Seilah's body during the second Time Skip.
- Not Quite Dead: Kyôka absorbing her curse power doesn't kill her as they both believe, although it brings her close to death. Mirajane saves her life by using her Takeover powers on her.
- Oh, Crap!: To say she reacts badly to Cana saving the guild and allowing Fairy Tail to actually counter and attack is an understatement.
- One-Winged Angel: Accessed by using Macro on herself and removing her limiter. Her horns grow twice as large, she gains Glowing Eyes of Doom with Extra Eyes elsewhere on her body, including the palms of her hands, her Minidress of Power splits into detached sleeves, and she gains even more runes on her body, including her now bare chest.
- People Puppets: She can control people to do whatever she wants through her Macro curse.
- Psycho Lesbian: Seems to be in a sexual relationship with Kyôka, and promises terrible vengeance against those who embarrass her in front of Kyôka.
- Psychotic Smirk: Flashes this right before the Fantastic Nuke lacrima she ordered Elfman to plant in Fairy Tail's headquarters detonates.
- Red Baron: "Goddess of the Chill Moon Seliah".
- Red Eyes, Take Warning: Despite her seemingly demure nature, her eyes are an early indicator of how dangerous this demon really is.
- Sadistic Choice: She makes Elfman choose between letting Lisanna die by his own hand and obliterating the rest of his guild so his sister can live.
- Sole Survivor: For a given value of "survivor", but Mirajane uses her Take Over on her after her defeat and near-death to make her one of Satan Souls, and Mira describes it as "saving" her life. In which case, this technically makes Seilah the only surviving member of the Nine Demon Gates after Zeref's death at the end of the original manga.
- The Stoic: She shows no expression, not even sadistic glee, as she forces Elfman to strangle his sister Lisanna. When her plan to destroy Fairy Tail goes up in smoke, however, this slowly but surely ceases to apply.
- Tattooed Crook: She has markings on her forehead and shoulders, though they appear more to be runes of some kind, rather than tattoos.
- Throw the Book at Them: Is shown doing this to Mirajane, with several floating books all pelting her at once. The anime shows her summoning these books from nowhere.
- Unstoppable Rage: Her One-Winged Angel form in a nutshell. Her usual cool demeanor is entirely replaced once her limiter is removed. Indeed, she goes so berserk in this form that he has to use Macro on herself just to stay focused on her target, or she'd be liable to destroy everything in sight.
- Voice of the Legion: In her Etherious Form. Her combat cries sound like multiple voices screaming all at once.
- Wicked Cultured: Not only is she a Badass Bookworm, she constantly refers to everything going on around her as if it were the plot of a novel, even going so far as to as to comment on events as if she were a literary critic.
- Yandere: Wanting to kill Lisanna in front of Mirajane just because Elfman embarrassed her in front of Kyôka clinches it.

A skeleton preacher who is obsessed with understanding the dead through research and experimentation. His Necromancer curse allows him to create and control the living dead.
- Back from the Dead: Downplayed. A Historia of him is created via Juvia's memories in the Alvarez Empire arc. He's defeated alongside Zancrow by Juvia and Merudy's Unison Raid.
- Badass in a Nice Suit: He wears a shirt with tie underneath his robe.
- Badass Long Robe: It goes with his Badass Preacher look.
- Badass Preacher: His clothes, staff, and tendency to speak as though he's giving a morbid religious sermon make him a great example. It's no wonder he's recognized as the Black Archbishop.
- Character Death: Juvia enters his body and blows him apart from the inside out.
- Dem Bones: He is a demon who resembles a reanimated skeleton.
- Didn't See That Coming: His defeat by Juvia comes after he's sure he'd torn her body apart. He didn't expect her to turn into water and destroy him from the inside.
- For Science!: His obsession with recreating a corpse to appear just like itself when it was alive pretty much boils down to this. Beyond that, he doesn't even care that Silver, his crowning achievement, plans to betray the guild.
- High Collar of Doom: Extends all the way over his head.
- Intangibility: A result of his Voluntary Shapeshifting. Gray can't even touch this guy; he just phases right through the ice. Then he makes the mistake of getting close enough to Juvia for her to enter his body and blow him up from the inside out.
- Keystone Army: If he is defeated, all of the corpses he reanimated will all die (again) as well. Silver informs Juvia of this, hoping that it will stop Crawford once and for all, despite knowing full well that he will also die if this happens.
- Love Is a Weakness: He apparently believes this, and taunts Juvia by saying her love for Gray made her hesitate in killing him, making her weak. She gives him a Shut Up, Hannibal! he won't soon forget by blowing him up from the inside, making sure it's the last thing he remembers.
- Mad Scientist: His obsession with recreating the perfect corpse to make it indistinguishable from when it was alive gives him this vibe.
- Magic Staff: He carries a khakkhara that can release blasts of dark energy at his enemies.
- Mouth Stitched Shut: While this doesn't hinder his ability to speak, it gives him a very creepy appearance.
- Necromancer: His Necromancy curse lets him bring people Back from the Dead and control them, including Crawford and Gray's father.
- Our Liches Are Different: He's a demon, but has the appearance and abilities of a lich.
- "Pop!" Goes the Human: Well, technically he's a skeletal demon, but in the end this is how he goes out, courtesy of Juvia.
- Red Baron: "The Black Archbishop Keyes".
- Scary Skeleton: While not the strongest member of Tartaros, he's still a skeletal necromancer with an ominous air to him and defeating him would be key to freeing Silver Fullbuster and allowing his soul to rest in peace.
- The Stoic: When confronted by Taurus and Aries' attacks, he doesn't even so much as blink (not that he could blink). His shock as Juvia enters his body and destroys him from within, on the other hand, manages to prove that he's Not So Stoic.
- Strike Me Down with All of Your Hatred: He eggs Juvia on to kill him, confident that she doesn't have it in her to do it because if he goes down, so does Gray's father. Too bad for him, it doesn't work.
- Super Speed: He can outpace Natsu while simultaneously dodging spells cast by Juvia in his mist form.
- Taking You with Me: An unintentional version occurs when Juvia tears him apart from inside his body, only to be infected by Devil Particles in the process.
- Warrior Poet: Everything he says sounds like a fancy, if morbid religious sermon.
- Weak, but Skilled: Silver says that as far as the Nine Demon Gates go, he's not particularly dangerous in a fight. His true talent lies in his necromancy abilities, which alone makes him an invaluable member of the team. Furthermore, his enormous speed combined with his intangibility made him the most difficult Tartaros demon to damage for the Fairy Tail wizards at least until Juvia deliberately let herself be absorbed by him.
- You Will Not Evade Me: After Wendy and Lucy try escape from him using Happy' and Charles' Max Speed, he reappears in a corridor just in front of them. However, Gray foils his stand.

A violent savage who is always itching to slaughter humans whenever he can. He uses his "Tenga Goken"note curse to transform his multiple arms into blades that can slice through anything.
- Absurdly Sharp Blade: His curse involves these, though they're not visible. He constantly claims that there's nothing in the world he can't cut, which has quite a bit of truth given he is able to literally slice through Wendy's winds and is only defeated because she makes them faster than he can cut through.
- Ax-Crazy: Quite eager to start slaughtering humans. His epithet "Child Slicer" doesn't help, and implies that he was the one who cut up the entire town Gray and Juvia went to. Definitely proves it during his fight with Wendy.
- Blade Below the Shoulder: In his One-Winged Angel form, his lower arms turn into black swords that he claims improves his cutting power even further.
- Back from the Dead: Downplayed. In the Alvarez Empire arc, Neinhart creates a Historia of him that attacks Wendy, who's still weakened from her fight with DiMaria. With Carla's help, however, Wendy manages to pull herself together enough to defeat him.
- Blood Knight: Unlike Torafuzar, he states he doesn't care about demon dignity as long as he can fight something. He's downright excited when Wendy turns out to be a Dragon Slayer because he thinks it'll make this fight much more entertaining.
- Child Hater: He doesn't take Wendy seriously at all, even going so far as to refer to her as "midget".
- Combat Tentacles: His tentacle-like limbs can be used like this.
- Dropped a Bridge on Him: After he's killed in the explosion of Face, he pops up in Hell's Core, ready to get his revenge on that "brat" who beat him. It just so happens he showed up moments before Mirajane blew it up.
- Foil: To fellow member Torafuzar. Both are the largest members of the Nine Demon Gates, possess great physical strength at their disposal and are extremely fast despite their size, and take pride in their power. However, Ezel claims as demons they have no use for honor and dignity, while Torafuzar believes that such things are necessary to their station. Ezel is a Blood Knight who delights in watching his enemies struggle and will drag fights out if he feels he can get more entertainment out of them, while Torafuzar is a No-Nonsense Nemesis who prefers to finish fights quickly and takes no pleasure out of torturing his victims.
- Kick the Dog: He prepares to crush Wendy underneath his Combat Tentacles until he gets the bright idea of wanting to eat Carla after she tries to save Wendy. Bad idea.
- Multi-Armed and Dangerous: He possesses four arms and seven tentacle legs, all of which can slice through anything.
- Nice Job Fixing It, Villain!: Ezel is responsible for having Wendy go from Tag Along Kid to a full-fledged Dragon Slayer after his attempt to eat Carla, prompting her to eat the air surrounding Face and unlock Dragon Force.
- One-Winged Angel: His "Slasher Form" has him gaining bigger fangs, a samuraiesque armor and huge black blades in lieu of his arms. However, it's still not enough to defeat Wendy's Dragon Force.
- Red Baron: The name "Dôjigiri", a legendary Japanese sword, references his ability to turn his arms into swords. Ironically, said sword is a demon-slaying weapon in real life.
- Shout-Out: His epithet and attacks refer to the five greatest Japanese swords: Dôjigiri, Onimaru, Juzumaru, Odenta and Mikazuki. Except for Odenta, all others were quoted.
- Storm of Blades: His curse involves huge, invisible Absurdly Sharp Blades that seem to extend from his hands. In his One-Winged Angel form, his hands turn into blades that improves their cutting power even more.
- Sword Beam: His curse makes him arms so sharp they can generate flying slashes of energy. His curse can even cut through one of Wendy's spells, but it was not enough to overcome her Dragon Force mode.
- Torso with a View: This is how his Historia is dispatched, courtesy of Wendy in Dragon Force punching a hole through through his chest with Carla's help.
- Underestimating Badassery: He calls Wendy a "midget" and expresses annoyance that she won't give him the fight he's craving. Oh, she gives it to him, alright.
- Would Hurt a Child: Lives up to his moniker of "Child Slicer" during his fight with Wendy.
- Wrecked Weapon: In the anime, Wendy shatters one of his arm-blades before she blasts him through Face to destroy the structure's physical form.

A no-nonsense shark demon who prefers to kill his foes with efficiency rather than cruelty, unlike many of his Etherious brethren. His curse power, Tenchi Kaimei, creates a wave of poisonous black water.
- Absurdly Sharp Blade: Just one of his shoulder fins is enough to partially break through Loke's Regulus magic, giving him a nasty cut on his arm.
- Artistic License Chemistry: The poisonous properties of his curse comes from toxic levels of carbon in the water. While carbon is indeed toxic to humans at ridiculously high levels (just like anything else, really), the amount of carbon necessary to kill a human being - even while being completely submerged in it - in five minutes or less would have to be at such high and concentrated levels in water to the point where it would no longer be a liquid.
- Blade Below the Shoulder: He has one large, razor-sharp fin attached to each elbow; they are his primary form of offense in his base form. Strangely, he loses them in his Etherious Form, leaving him to rely on simple yet powerful punches from his massive arms.
- Chrome Champion: He can harden his body into metallic-looking plates that are hard enough to hurt Gajeel after punching him in his Etherious form. He proudly claims his defense is the strongest of the Nine Demon Gates, but he is helpless against opponents that can use steel attacks.
- Fish People: His Etherious Form doesn't have any shark characteristics, just looking like a hulking humanoid fish.
- Foil: To fellow member Ezel. Both are the largest members of the Nine Demon Gates, possess great physical strength at their disposal and are extremely fast in spite of their size, and take pride in their power. However, Torafuzar believes that they should have honor and dignity about their station, while Ezel claims as demons they have no use for such things. Torafuzar is a No-Nonsense Nemesis who prefers to finish fights quickly but taking no pleasure out of torturing his victims, while Ezel is a Blood Knight who delights in watching his enemies struggle and will drag fights out if he feels he can get more entertainment out of them. Even their abilities stand in contrast; Torafuzar can harden his body with metallic plates, boasting of having the strongest defense of the Nine Demon Gates, while Ezel can turn his arms into blades, boasting that there's nothing in the world he can't cut through. They're even both defeated by a Dragon Slayer who took exception to them attacking a loved one.
- Grimy Water: His water is black and poisonous, being highly concentrated in carbon. Later the carbon becomes the cause of his defeat.
- Hoist by His Own Petard: His Tenchi Kaimei Curse creates an area of poisonous black water that is rich in carbon. Gajeel absorbs the carbon in the water to turn himself into steel, and finish him for good.
- Home Field Advantage: His Tenchi Kaimei Curse provides a three-fold advantage to him: 1) It summons a mass of black water that he can swim through effortlessly and gives him the movement advantage while he whales on them; 2) Most of his opponents aren't amphibious in nature while he is, meaning he can outlast them and let them drown; and 3) even if his opponent can swim through the water and not drown, the poisonous nature of the water thanks to the excess carbon within it, which he is immune to himself, will poison his enemies and kill them within five minutes.
- Unfortunatey for Torafuzar, it is eventually turned against him as Gajeel ends up absorbing the carbon in the water to turn his iron body into steel (which can cut through Torafuzar's defense), and defeat him.
- Hulking Out: His One-Winged Angel state becomes him increasing the size and form of his shark body.
- Kick Them While They Are Down: He tries to kill Lucy once she's exhausted after her battle with Jackal. Good thing Gajeel came through for her.
- Lightning Bruiser: Despite his size and bulk, this guy is fast.
- Making a Splash: Fitting his shark theme he can summon a giant wave of a poison black water to submerge an entire area.
- Megaton Punch: His main method of attack after transforming and using his Curse is to just punch his opponents to death. Considering his arms are massive and most foes are too busy drowning and/or being poisoned to death at the same time, it's very effective.
- No-Nonsense Nemesis: Rather than waste time torturing Lucy, he just wants to get it over with and kill her. The fact that Jackal and Lummy disagree annoys him, eventually making him stomp off. Later he decides to use his curse which eliminates Natsu from battle for the moment along with everyone else. Had Levy not given Gajeel air everyone would had been taken out by the poisonous water.
- No-Sell: He is a master in the water, allowing him to swim through Aquarius' tidal waves without breaking a sweat.
- Pragmatic Villainy: Unlike Ezel, he's not one to start causing chaos just for fun. He also criticizes Jackal for toying with Lucy instead of finishing her off.
- Punch-Clock Villain: While he does seek to kill humans under orders he does not take it personally only seeing it as a mission to accomplish.
- Red Baron: Torafuzar "The Dark".
- Shark Man: His head and arm blades resemble fins. Furthermore, "Torafuzame is Japanese for "Zebra Shark". He also has Super Swimming Skills and is capable of swimming through Aquarius' attacks.
- Spell My Name with an "S": Fan groups call him "Torafusa".
- Super Toughness: He parries a blow from Gajeel, who had converted his skin into metal, using only his forearm... and Gajeel was the one who got hurt from the punch. In his Etherious From, his skin can be converted into a hard, shiny substance that causes Gajeel's iron Dragon Scales to crack when he tries punching him. Too bad for Torafuzar that it doesn't protect him from things harder than iron, such as steel.
- Supernatural Suffocation: He weaponizes his Curse this way, drowning his enemies in the poisonous waters he himself is immune to. The only way to save yourself is to be a water breather, defeating him, or somehow having a way to drain the water out.
- Superpower Lottery: Another powerful demon to deal with. First he's pretty quick even outside of water, his curse involves creating a huge area of water that's poisoned by carbon, even if you can keep your mouth shut you still can be affected by the poison, and if you can fight back he still can turn his body into steel, making him a pretty strong member for the Nine Demon Gates.
- Sweat Drop: His reaction to Natsu and Gajeel punching each other during their fight.
- Top-Heavy Guy: His arms are so large that his hands lie flat on the ground when at rest. Up to Eleven in his Etherious Form, having a Primal Stance when not submerged in water.
- Would Hit a Girl: As Aquarius makes full use of her Water Magic to sweep Jackal away, Torafuzar uses the water to his avenge and slashes her.

A cackling cyclops who is obsessed with wealth. Using his Revolution curse, he can absorb the souls of any living thing he touches and use their powers for himself.
- Achilles' Heel: He cannot assimilate anything without a soul. Natsu exploits this by beating him with a big rock.
- Acrofatic: He's more nimble than he looks. When channeling Hades's soul, he's firmly in Lightning Bruiser territory.
- Ascended Fanboy: He reveals himself to be a huge fan of Hades and his guild. And what's even better for Franmalth is that he has the soul of Hades in his possession and has access to all his magic powers.
- The Assimilator: His Combat Tentacles-like limbs don't just drain energy. Leave them attached long enough, and you get absorbed, powers included.
- Baleful Polymorph: After surviving the destruction of Hell's Core, he turns into a tiny parasitic mushroom creature that is significantly cuter and more harmless than his usual form.
- Black Eyes of Evil: His eye is black with a yellow pupil, adding to his overall inhuman appearance.
- Beware the Silly Ones: He is no less dangerous than his fellow demons despite his ridiculous appearance, as he gleefully points out when he whips out Hades' soul, proving to be just as formidable as Hades was on Sirius Islandnote despite looking like a total mockery of him.
- The Cheerleader: Reduced to this in his powerless mushroom form, rooting for Tartaros's remaining forces.
- Cheshire Cat Grin: His face is stuck in a virtually permanent grin.
- The Collector: He has collected countless souls, including dead wizards such as Hades, which he loses upon his defeat.
- Combat Tentacles: While his "tentacles" are actually his limbs, his rubber-like body can sprout more of them from almost any part of his body. And those limbs can sprout even more.
- Cyclops: He usually has one large, glowing eye in the center of his face, usually visible through his armor's face mask.
- Everybody's Dead, Dave: Counting the other members whose ultimate fates are left hanging, Franmalth is the only named member of Tartaros who is indisputably left alive in the end, stuck in the form of a helpless mushroom.
- Evil Is Hammy: He's big, fat, greedy, and slobbers at the mouth when he cackles. Subtlety, thy name is not Franmalth.
- Evil Laugh: "Gehehe!"
- Fat Bastard: His constant obsessing over the quantitative worth of everything, from the actions and loyalty of his teammates to the souls he's absorbed, makes him the perfect embodiment of Greed among the demons.
- Hoist by His Own Petard: Absorbing Lucy's celestial spirits backfires when Lucy tries to call them back to the spirit world to save them. Franmalth finds himself being sent to the spirit world along with them, forcing him to release them to free himself. Lucy then bluffs him by pretending that Natsu is also a spirit, which spooks Franmalth into freeing Natsu too.
- Mad Libs Catch Phrase: "How much is X worth? How much?"
- Maniac Tongue: It tends to wag and dangle out of his mouth while he laughs.
- Morally Bankrupt Banker: He measures his teammates' value by how they use the guild's finances. For instance, he scolds Tempester for using his Devil Particles, saying they were too expensive to use casually, and even dismisses Doriath for being too expensive to justify his usefulness.
- Mushroom Man: He becomes a tiny mushroom creature after narrowly avoiding the destruction of Hell's Core.
- Narm: An In-Universe version occurs when he transforms into Hades, one of Fairy Tail's most terrifying opponents. Natsu, Lucy and Happy are taken aback by how goofy he looks, shattering whatever threatening image he may have had. At least, at first...
- Nigh-Invulnerable: Natsu's attacks just piss him off. He even No Sells his Thunder-Fire Dragon's Roar. Turns out it's because they're magic attacks and he can absorb them. He can even absorb the damage of physical attacks from Natsu. The flaw in his defense is that he can't absorb damage by things that lack souls, a large rock for example.
- Not Quite Dead: He barely survives the destruction of Hell's Core by attaching himself to Happy as a mushroom-like parasite.
- Power Parasite: Absorbing the souls of wizards and spirits gives him access to their magical abilities and changes his appearance. As Aries he can use her Wool Magic, and he has Super Strength as Taurus.
- Red Baron: Franmalth "The Armored".
- Rubber Man: His limbs can stretch out to grab something at the opposite end of the room. Very helpful, for The Assimilator.
- Spikes of Villainy: Can be seen on his body once he bursts out of his armor.
- Squashed Flat: The end result of being repeatedly bashed with a large rock by Natsu. He technically died from it, too.
- Supernatural Gold Eyes: He has only one of them, being a Cyclops, but it counts given that he is a demon.
- Tempting Fate: After being beaten, he boasts of his guild's Resurrective Immortality and goes to pay Hell's Core for a visit right when Mirajane blows it all sky-high. Fortunately for him, he barely manages to survive.
- Villain Forgot to Level Grind: Subverted. When Franmalth reveals his trump card to be the soul of Hades, Natsu gloats that he already took Hades down once before, and figures beating someone of his level a second time will be a cakewalk with his own current level of power. Unfortunately for Natsu, he realizes his power alone still isn't enough to match Hades's power in his prime.
- Villainous Breakdown: He goes completely berserk when he realizes Project Face's failure, which makes him all the more dangerous since he unloads Hades' terrifying magic on Natsu, Lucy, and Happy.
- Your Soul is Mine!: He has the power to steal others' souls, either by attaching his tentacle-like arms to them or taking them after death. It's not clear what would happen to humans who lose their souls, but for Celestial Spirits, he absorbs their entire bodies.

A bunny-girl demon and subordinate of Kyôka who runs Hell's Core, a lab where injured demons are restored and new demons are made. Her Slippery Curse allows her to slide across surfaces and deflect all sorts of attacks.
- All Girls Want Bad Boys: She is head over heels for guys like Jackal and Tempester, ignoring their psychopathic tendencies.
- Character Tic: She often strikes a melodramatic pose by pulling her arm over her face and turning super-realistic for a moment.
- Clone Army: It turns out after she's killed by Jackal that Lummy was mass-produced, leaving behind countless copies for Elfman, Lisanna, Jet and Droy to clean up.
- Cute and Psycho: As adorable and childish as she is, she has no trouble disfiguring girls she thinks are prettier than her.
- Eyes Always Shut: Her eyes usually remain closed unless she undergoes her Art Shift.
- Faux Affably Evil: She acts like a ditzy girl, but is every bit of a remorseless, human-hating demon who lives to see humans maimed and disfigured.
- Labcoat of Science and Medicine: She wears a fluffy one decked out with pompoms.
- Mad Scientist: She is the medical demon responsible for reviving defeated demons in Tartaros, and she enjoys turning pretty human girls into grotesque monsters.
- Mood-Swinger: She tends to switch to a hilariously melodramatic personality with a more realistic-looking face from time to time.
- Nice Job Fixing It, Villain!: Her decision to pump Mirajane full of demon factor fluids to turn her into an ugly bug instead rejuvenates her, since Mirajane already specializes in absorbing demons. It also gives Mirajane a connection to Hell's Core, allowing her to blow it up once Lummy blurts out its purpose, which leaves one Demon Gate dead, another in a helpless state, and the guild as a whole without its advantage of Resurrective Immortality.
- Plucky Comic Relief: She is incredibly goofy, and her obsession with all the "hunks" in the guild is Played for Laughs, which makes her stand out among the cruel, mostly humorless demons.
- Spin Attack: Her curse allows her to perform this attack.
- This Loser Is You: She is a Fangirl who clings to good-looking male villains despite the horrifying atrocities they commit. This behavior gets her killed by one of the very villains she swoons over.
- Unusual Ears: Her rabbit ears are the only demonic trait she has.
- Weak, but Skilled: She's not strong like the Demon Gates, but she does help repair and remodel the other guild members when they are killed.
- Your Head A-Splode: Jackal grabs onto her face and blows her to smithereens after she grates on his nerves.

A frog-octopus demon that assists Kyôka in torturing prisoners.
- Bullying a Dragon: Kyôka leaves him alone with Erza after helping torture her. When she comes back, Yakdriga has already suffered Erza's wrath.
- Electric Torture: Kyôka uses his electrical powers to this effect on Erza.
- Intangibility: He can phase his body through walls.
- Mix-and-Match Critters: He has the head of a frog, the body of an octopus, and bug-like antennae.
- Shock and Awe: A more natural version of this trope, as his electric charge doesn't extend beyond his tentacles, only allowing for electrocution on contact.
- Spell My Name with an "S": His name is spelled "Yakdoriga" in the English dub.
