~ Mard Geer Tartaros to E.N.D.. |
Mard Geer Tartaros is the main antagonist of the Tartaros arc in the manga/anime Fairy Tail. He was an Etherious and founder of the Dark Guild Tartaros. He was known as the Underworld King, having placed himself in charge of the guild in E.N.D.'s absence.
He was voiced by Toshiyuki Morikawa (who also voiced Naraku, Yoshikage Kira, Lord Boros, Sephiroth and Griffith) in Japanese and Vic Mignogna (who also voiced Rohan Kishibe, Broly, and Malzahar) in English.
Appearance

Mard Geer's Etherious Form.
Mard Geer is tall, lean and has the appearance of a young man. Often seen wearing a smirk, Mard's black hair is long and wavy, reaching his shoulders even whilst the majority is tied up in a very large ponytail. Additionally, his messy bangs all but obscure his dark, slanted eyes.
For clothing, Mard's dons a long, black jacket trimmed with a light-colored flame pattern; the lapels are a matching lighter color as well. The cuffs of his jacket are rolled up, revealing a light-colored inside, which contrasts the black outside of his jacket, and have a black line cutting through the edge of the fabric. The jacket itself is tattered and splits into four torn fabric segments at the tail. Beneath the jacket, Mard wears a frilly black v-necked shirt, lined in a lighter color, that closes down the middle and is adorned with a buckle just below his clavicle; just below this is a piece of fabric that Mard keeps over this shirt but under his jacket, that circles the majority of the lower half of his torso. The rest of his attire is simple, consisting of light-colored pants that lay lazily over the top of rather plain black boots and have, on each leg, a seam running down the middle, as well as two pairs of buckles that form an X on the thigh and lower calf. However, the buckles on each thigh later disappear, leaving only the ones on each calf.
Like other Etherious, Mard is able to transform into his true, more powerful form. His body becomes more muscular, and his skin darkens and gains the ragged pattern of his cloak. He gains long, dark horns on his forehead, jagged teeth, and retains his ponytail. Mard's fingers are replaced with claws and his ears become elongated and elf-like. He gains large, bat-like wings that are both light and dark in color. Feathers also sprout from his wrists and collar.
Personality

Mard Geer feels "anger" for the first time in a long time
Often seen smirking, Mard is a cool, collected, yet arrogant man who plays himself off as being extremely intelligent; he quite regularly refers to himself in the third person. Also, much like the rest of his kind, Mard belittles humans, and thinks of them as nothing more than insects. Indeed, he finds the mere thought of letting a human live when given the chance to kill them a tragedy, and is not above torturing his subordinates when they cause him any sort of inconvenience (ironically, not much later, he begins to understand, after fighting Sting and Rogue, that toying with humans can be quite enjoyable, as he ultimately finds their ignorance and belief in things such as hope incredibly amusing).
Additionally, Mard takes great pride in being one of Zeref's Etherious; he also has a habit of referring to Cube as his "garden", and appears to love it enough to make Fairy Tail pay for bringing harm to it, even though he noted that ultimately, it didn't matter in the slightest. However, after many outsiders intruded and Cube was destroyed, Mard began to feel, for the first time in years, anger, an emotion he expressed himself to have forgotten long ago.
Mard is also rather intolerant of human emotions, having decided to kill his for the sake of putting his intellectual side first. He also cares a great deal for E.N.D.'s safety whilst in book form, setting his tome down before proceeding to unleash his fury against Natsu and the Twin Dragons, as he was unsure of what his rage would do to the book. When throwing away his calm nature, Mard's arrogance grows in leaps and bounds, as after he emerged unscathed from a full-scale assault from his Dragon Slayer opponents, he merely sat upon his throne and goaded them by saying that he has yet to use his Etherious Form, as well as that they should give up. Though when variables that he did not predict come into his equation, such as Gray receiving Silver's Ice Devil Slayer powers, even he can lose his composure and exhibit shock and awe.
Curse and Abilities
Mard Geer Thorn Curse
- Thorns: Mard summons a series of size-varying thorny vines (optionally done with the use of several hand gestures) from whatever surface he desires, which are capable of passing through the target's body, and ensnares his target of desire, rendering them, at least temporarily, incapable of movement.
- Rose Explosion: Mard creates a rose composed of Curse Power that engulfs its nearby surroundings in a destructive explosion.
- Prison Flower: Mard grows a large, monstrous flower with spikes and chains around its bulb which he describes as "the prison flower which blooms in the Underworld" that can use its vine to attack opponents. It is also able to contain others inside its bulb, as seen when Jiemma emerged from it.
- Dea Yggdrasil: Mard creates a massive spinning sphere from his hand from where an immense wooden beam is fired at the target.
- Alegria: By swiping his hand, Mard is able to make use of this Curse, which turns Cube into a gigantic monster called Plutogrim; a beast which Mard describes as being a gigantic prison. The name of the Curse refers to the joy that one is supposed to feel in regards to becoming one with Cube.
Memento Mori
- Telepathy: Mard is able to hijack Warren Rocko's mental communication and talk to the Fairy Tail Guild's members. The original Telepathy user experiences great pain upon Mard entering the mental link, and a deafening noise resounds inside minds of the connected people. Furthermore, Mard is also able to telepathically communicate with everyone in Tartaros.
- Etherious Form: Mard Geer is able to enter the Etherious Form that much of the rest of his race employs.
- Flight: By using his bat-like wings, Mard can fly at incredible speeds.
- Sensor: Mard was seen to be aware of the battle happening between Mirajane Strauss and Seilah, commenting on how the former's attempt at demonic powers could never match the power of a real Demon.
- Expert Hand-to-Hand Combatant: Mard has displayed considerable skill in unarmed combat, having been capable of repelling simultaneous assaults from Sting Eucliffe and Rogue Cheney, two Dragon Slayers, with no apparent effort, even when these came from two opposing directions or were enhanced with Magic, accomplishing all of this with one hand, with the other clutching the book of E.N.D.
- Enhanced Strength: Mard's physical strength is remarkable even when in his human form, allowing him to easily parry Rogue's Shadow Dragon's Slash from behind his shoulder with a single hand, as well as to subsequently throw the opponent several meters away from him with that very same hand.
- Enhanced Speed: Mard has shown himself to be very agile, able to quickly avoid the Celestial Spirit King's attack by jumping high into the air as well as evade his Meteor Blade. He has also displayed acrobatic prowess, able to perform multiple somersaults mid-air.
- Immense Durability: Mard Geer is durable even whilst in his human form, emerging from his earlier battle with Sting and Rogue with little more than several scratches, being able to withstand powerful blows from Natsu, including direct punches to the head, and even various combination attacks from all three of the aforementioned Dragon Slayers, including a strike from Natsu's Lightning Fire Dragon Mode, and emerge with, again, only minor scratches. Indeed, the only thing that could inflict lasting damage on Mard was Gray's Ice Devil Slayer Magic.
- Immense Curse Power: Being one of the most powerful Etheriouss created by Zeref as well as the strongest demon of Tartaros, Mard Geer has vast reserves of Curse Power. His power is so great that even some members of the Nine Demon Gates (including Kyôka) are scared of it and it is enough to subdue and force every demon of the dark guild to execute any order without objecting it.
Trivia
- It's ironic he sought to revive E.N.D. when he engaged Natsu (who was really the demon) and attempted to kill him.
- His death mirrored the fate of Larcade Dragneel as both were demons created and destroyed by Zeref after they were deemed useless by him as he favored Natsu (E.N.D.) over them.
