Mard Geer Tartaros

Mard Geer (マルド・ギール Marudo Gīru) is an Etherious of the Dark Guild Tartarus and is known as the "Underworld King".

Appearance
Mard Geer's looks resemble those of a young man. He sports shaggy hair of dark color, long enough for its bangs to reach his nose and likewise, strands of hair to cover the sides of his face all the way to below his shoulders. On the back of his head, Mard's hair forms a big ponytail. His attire consists of a dark colored shirt and a light colored cape with a pattern of flame that is torn into stripes on the bottom. Mard also wears light colored trousers that are tied by straps on his thighs and slightly above his ankles, as well as boots of a dark color.

Personality
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. 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.

Tartarus arc
Mard Geer appears for the first time inside of Tartarus' HQ. Sitting on a throne in his room and holding a book with the letters "E N D" written on the cover, Mard talks about Zeref's Demons, dubbing them as being the "Etherious", beings superior to humans. Seemingly reassuring the Master, Mard states that the darkness of Hell's gate will soon appear and eat up the world's light.

Shortly after, Mard is approached by Kyouka, who informs him that the plan to activate Face failed, and that the resurrection of Franmalth and Ezel was halted by members of Fairy Tail. Seemingly bemused, Mard tells Kyouka that Sayla too was only just defeated, causing the Demon woman to ask for E.N.D. to be summoned to assist them; however, Mard informs her that there is too much Magic power present in the world for E.N.D. to properly resuscitate, and, though Kyouka reminds him that that was the entire point of using Face, he states that their plans will still come to fruition. Asking Kyouka about their goals as a guild, Mard proceeds to attack the woman when he finds out that she was "playing with humans", a punishment he states she deserves for daring to interact with them too much. As Kyouka tries to thank him for righting her wrong ways, Mard decides that he may have to use Alegria given the current situation. Making his move, Mard high-jacks Warren Rocko's Telepathy, and uses it to introduce himself to the Fairy Tail Guild. Bidding them farewell, the man makes use of Alegria, which proceeds to warp and deform Cube, swallowing everything and everyone present inside. Kyouka warns the Demon that he is sacrificing their own troops, though Mard seems not to care, berating the human race as he waits for his command to finish. However, as the morphing of Cube comes to an end, Mard senses that one of the Fairy Tail Mages managed to avoid being captured, laughing as he debates whether or not Lucy Heartfilia has good or bad luck for being able to slip free from Alegria's grasp.

Mard then uses Telepathy one more time, informing the members of Tartarus that Alegria has gotten rid of the intruders so the Face project can continue. However, he also reveals that Lucy has escaped the effects of Alegria and promises that if any of the soldiers kills her, they will receive the title of Nine Demon Gates, in the case of the current Nine Demon Gates, a prize. This prompts the entire Tartarus to chase after the Mage. Mard later stands before the Celestial Spirit King, after the latter appears thanks to Lucy's sacrifice and destroys the transformed Cube.

He expresses his surprise that someone was able to summon the Celestial Spirit King and then explains to him that the book he's carrying is the soul of E.N.D. The Celestial Spirit King then asks about their motive and Mard reveals to him that they are trying to revive their Master and reunite with Zeref. The Celestial Spirit King then questions if this is the reason for Lucy's wounds and sorrow, and when Mard confirms it, he is attacked by the spirit's sword. Mard envelops himself in a sphere of Curse Power and strikes the Celestial Spirit King, however, the latter counters it with ease. Wasting no time, Mard summons thorns to pierce through the spirit's body, claiming this to be the end, but the Celestial Spirit King cuts through them and replies with an attack of his own, Meteor Blade. The technique causes great destruction, although it misses its target, Mard, who commends the king for his efforts. Mard and the Celestial Spirit King continue clashing as the latter lends Aquarius' power to Lucy Heartfilia.

Mard and the Celestial Spirit King continue the battle, with the former noting that the latter is becoming slower. Mard attacks with his Curse one more time, claiming that this is the end, however, the Celestial Spirit King defends himself and proceeds casting Galaxia Blade. While shielding himself, Mard smirks, asking whether the Celestial Spirit King is willing to sacrifice Lucy, however, it soon turns out that this spell instead cancelled Alegria. As the Celestial Spirit King begins vanishing, Mard starts turning into stone. As he gives a warning that the malice for humankind won't be forgotten, Mard ends up being fully petrified.

Curse and Abilities
Thorn Curse (荊の呪法 Ibara no Jūhō): A Curse of Mard's which allows him to create a series of thorny rose vines, the Curse can be used as a means of "punishment" for those who cause inconvenience to Mard, as the vines wrap around the target extremely tight, digging the thorns rather deep into their body.


 * Thorns (荊, イバラ, Ibara): 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.
 * Thorn Charge: By focusing his Curse Power around his index and middle fingers, Mard proceeds to point them to the target. Afterwards, he covers his person with a large, thorn-imbibed shield of Curse Power, to which he uses to protect from attacks. (Unnamed)
 * Thorn Projectile: Swiping his hand upward with his index and middle fingers, and thumb outstretched, Mard directs several thorns at their desired target. Its effects are, however, unknown due to its original casting being blocked entirely. (Unnamed)

Alegria (喜びか, アレグリア, Areguria): 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.

Telepathy (念話, テレパシー, Terepashī): 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 Tartarus.

Sensor: Mard was seen to be aware of the battle happening between Mirajane Strauss and Sayla, commenting on how the former's attempt at demonic powers could never match the power of a real Demon.
