Jason Gaebolg

"Black Knight" Jason Gaebolg (birth name Pluto Saturnalia) is a former apprentice of Hades. He was the strongest member of the guild Black Void, prior to its disbandment, and the leader of its strongest team, the Quasars. He served as the main antagonist of Aether and Samarra: A Budding Friendship, and Dragon Gunfire's Promotional Trial: A Battle of Strength and Wit.

Formerly a Dark Mage in Grimoire Heart, Jason became a cold and unfeeling man due to neglect and seeing the horrible actions of Dark Guilds. Jason then went on a quest to eliminate any and all Dark Guilds, through any means necessary. This quest led him to cofounding Black Void, a guild consisting of only former Dark Mages. After a while he encountered Alexander Doomkaiser and Luke Gandor (who later became his own students), forming the Quasars. After Black Void was disbanded and all the members arrested, Jason reformed the Quasars using new members, and swore revenge on Aether Cade and Samarra Inari. Although his plan to kill Aether on his island failed, and the Quasars were once again disbanded. He only managed to escape due to the timely intervention of Hyperion Lucifer. He is also the biological son of Cronus Saturnalia, the leader of Othrys. After the war between the Mage guild Dragon Gunfire and city-state Othrys, Jason was welcomed to Dragon Gunfire, and started the Spartoi Program as its program manager, a position he holds to this day.

Appearance
Jason is a fair skinned, muscular, young man. He has red eyes, and well kept short black hair. He often had an emotionless expression before the year he spent with the renewed Black Void guild. When activating the curse power of Mephiles his eyes turn completely black.

Jason often wore his Nightingale Armor, rarely taking it off. This armor is a full body suit completely covering his body up to his neck, and is entirely black. Under his armor he wears a beige long-sleeved shirt, and beige pants. To comfortably walk in his armor he wears thick black socks, as the armor's boots often function as his shoes. He wears a black cape with red on the inside as well, and a feather like protrusion appears on the front of his left shoulder.

Personality
Jason was once more emotional showing a great amount of love for his mentor, Hades, but great emotional pain when he was picked on by the Seven Kin of Purgatory, although he held a soft spot for Ultear, someone he considered a dear friend.

Due to his escapades as a member of Grimoire Heart, his soul was damaged to become cold and unfeeling. This cold calculating manner of his caused him to be ruthless in battle, not stopping until he defeats or kills his foe, as shown by his complete destruction of a dark guild killing everyone in it after they refused to disband. He's unwavering in his goals, even to achieve minor victories. He has reportedly threatened clients that wouldn't pay him, and scared all of his subordinates into submission in Black Void so that they wouldn't disobey him.

After the disbandment of Black Void, Jason became obsessed with vengeance on Aether Cade and Samarra Inari, willing to do anything, and pay anyone to kill them. After he joined Othrys he finally began to feel more compassion. He sympathized with Fragor, as he had been suffering under Othrys, and was incredibly angry when he confronted the Six Titans of War and the Cardinals about this fact. He even shot Darius Xerxes in the chest with his Black Bullet when he tried to calm him. Nowadays, as the program manager of the Spartoi, Jason still has trouble being nice to people, but is very kind to those he sees as friends, such as his subordinates in the Spartoi, and Ultear.

History
As a baby, Jason was found on the Grimoire Heart airship, being dropped off by an apparition (later discovered to be Hyperion Lucifer). Due to the incredible amount of magic power he was born with, Hades decided to raise him as his own and teach him magic. Over the years, Jason trained alongside the Seven Kin of Purgatory in the usage of magic. During this time he learned many magics, opting to learn magics similar to his master in homage to him. He also self taught himself the powerful spell Katsu. At the age of 12 Jason became a high-ranking member of Grimoire Heart, but the art of killing others began to take its toll on his mental state, creating his current personality. He soon left the Dark Guild.

Jason, along with Black Void's guild master, appealed to the Magic Council in order to create a new legal guild using former convicts. They reasoned that this would assist in the rehabilitation of said criminals, and allow them to reenter society. Although he managed to persuade them, the Magic Council kept their eyes on the new guild. Despite technically being a legal guild, Black Void took under the counter deals and took part in several illegal jobs. Jason later encountered Luke Gandor and Alexander Doomkaiser, and formed the Quasars with them, the former of which, Jason needed to defeat in one on one combat.

Magic and Abilities
Darkness Magic: Jason was taught Darkness Magic by his master, Hades, when he was young, wishing to be more like his master. In combat, this is Jason's most prominently used magic. Unlike Hades' magic however, Jason's is black in coloration, as opposed to purple, making it even more malefic and powerful. As a obvious master of this magic, Jason has a wide variety of and techniques miscellaneous skills at his disposal. He can coat portions, or his whole body in Darkness Magic in order to increase the power of his melee strikes, similarly to Natsu Dragneel with his Fire Dragon Slayer Magic and Laxus Dreyar with his Lightning Magic. Jason is also capable of creating a variety of weapons to fight opponents. His darkness can cover a wide area around him, either on solid surfaces or floating in the air, allowing him to corner opponents or control the battlefield. He describes Darkness as gravity, and when using his Darkness Magic to increase the power of physical attacks, the density of his magic allows him to crush almost anything with his might, including Adamantine, Black Steel, and even denser magical materials. This immense weight is due to tutelage from Bluenote Stinger, allowing Jason to also incorporate elements of Gravity Magic in to his Darkness, and crush foes with his spells' immense density. This even allows Jason to manipulate gravity to some extant, nullifying the effects of Gravity Magic, or any ability that attempts to mimic it, when used against him. He is just unable to directly influence gravity upon his opponent without casting a spell, such as Black Vortex. The same power is present in the power of all his spells, which is how they all have such immense crushing and piercing power. Through training against Matthew Drakon's Holy Elemental and Fire Magic, Jason's Darkness is also immune to the purifying effects of White and Holy Magics, as well as the overall light produced by such magics. It can't absorb light, but light will not eradicate his Darkness, seeming to have a sort of superiority over even Slayer Magics. It also possesses a high tolerance to heat and flames, similarly being unable to be burned away. Against both elements, despite not being able to absorb them, not without his Eternal Darkness spell, Jason is still capable of smothering them in darkness in order to eradicate such attacks. This allows Jason's darkness to even resist the heat and temperature of flash bangs, but not any sound waves that they produce. Jason also spent some time in Othrys, training with Pluto Morior in the art of Darkness Magic. After this training, Jason's skill in Darkness Magic ascended to even greater heights, increasing the strength of his Darkness to levels equal to the King of the Underworld.


 * Black Bullet: Jason makes a finger gun at his opponent and focuses his magical energy in his fingers, specifically the index and middle fingers. He then fires a black bullet of darkness magic from them.  The bullets are easily capable of tearing through flesh, and armor alike. With enough focus it can pierce the likes of Adamantine and Barrier Magic. This spell managed to crack the mask of Sykushi Strykri, and pierce through Darius Xerxes magically reflective armor, piercing his chest and causing him to immediately lose consciousness. The bullet itself actually almost killed him. Occasionally, when firing the bullet without chanting the spell's name, he often says "bang" or "pow". Jason has developed his Black Bullet to a degree that it can match the speed of Hyperion Lucifer's Light Beams, and even overpower them. Most people can't even process the incredible speed of the spell. Jason can also utilize blunted variations of the standard bullets, dealing heavy blunt damage without the intention of piercing the skin. These bullets aren't any slower than the standard Black Bullet, and can be incorporated into all of Jason's Black Bullet derivatives.
 * Duel Wielding: Jason "duel wields" his finger guns, shooting many bullets of darkness magic, that greatly damage his foe. He fires the bolts incredibly fast, almost like a machine gun, and the bullets can even take up the entire area in front of him, no matter what space he's occupying. Each individual bullet has the same level of power as the normal Black Bullet, but can also be changed to be simply blunt in damage.
 * Grenade Launcher: Jason charges Darkness Magic in his fingertips while making a finger gun.  This creates a sphere of his magic at the end of his fingertips. He then blasts his opponent with a large amount of magical energy, exploding on contact, and dealing a great amount of damage. It's power is like being hit by 100 Black Bullets at the same time, possessing both immense explosive and piercing power. The explosion also travels exclusively outwards from the area of contact, so even from point-blank range, Jason can't be harmed by the casting of this spell. Although he was interrupted by Seraph Kinmichi before he could utilize it, this spell was still powerful enough to kill an injured Aether Cade. Jason can also fire two Grenade Launchers at once utilizing both finger guns.


 * Eternal Darkness: Jason holds out his hand, absorbing the magical energy of an attack.  He then transforms it into Darkness Magic and blasts it back at his opponent.  This spell can only work on fluid based attacks (gas or liquid) and will not affect solids. The power of this spell is equivalent to, or greater than the power of the spell used against him. The reason it increases in strength is that the transformation of the spell into Darkness Magic infuses it with Jason's own magic power, and increasing the overall amount of power inside the attack.


 * Borderline: Jason swipes his hand, creating a line of Darkness Magic separating himself from his opponents for a long enough time to perform a counterattack. Anyone caught inside the spell's border, however, will be tossed around during the spell's brief period of activation, and bruise and cut anyone inside. Whoever was struck will often find themselves far away from their starting position. Despite this spell's great power, it is still generally used as a separation technique.


 * Dark Star: Jason forms a sphere of Darkness Magic in front of his fist or open hand, and slams it into his opponent. This sphere is highly condensed, dealing high amounts of crushing damage that can easily shatter bones. Jason can also detach this spell from his hand, using it to keep his opponents pinned to the ground, and continuously crush their body, or surround his fist in the sphere, making it an effective punching attack. It is considered Jason's densest Darkness Magic spell, and his most powerful directly physical spell. Only Jason is capable of lifting this spell, as it is made from his own magical energy, allowing him to telekinetically lift the sphere. No one else is capable of resisting its power.


 * Push: Jason covers his hand in Darkness Magic and strikes his opponent with an open palm, generating a shockwave that pushes them back and does great damage. This spell can also be used at a range, producing the same effect. The brief amount of time it takes this spell to activate, and the great force behind it, makes it incredibly difficult for an opponent to resist. This spell has so much force behind it that it can even crack bones and shatter strong metals. It even has enough power to easily push away a being as large and as strong as a Giant.
 * Stygian Blade: Jason holds out his arm, creating a blade made from Darkness Magic from his wrist. The blade is about the length of an actual sword, and is easily capable of cutting through materials as if it was a real one. Jason can even use this spell to cut through spells casted by his opponents, and other swords. Jason is also not limited in the usage of just one blade, and can summon multiple ones. When utilizing his Grudge spell, Jason can utilize the tendrils erected from this spell to create blades from multiple parts on his body. Jason can also freely extend and retract the length of his blade. He is also capable of using this spell to create a standard, double-edged sword, just as powerful as the normal variation, but instead held in the hands.
 * Black Vortex: This spell is essentially a black hole, but with it being more controllable than said stellar phenomena. Jason first touches his hand to the ground, spreading out his Darkness Magic all throughout the area's swallowing up anything that it makes contact with, before crushing it into pieces with its immense pressure.  Jason is capable of changing the pressure of this spell at will, ensuring that it won't kill an opponent unless he wants it to.  Anything absorbed inside can then be launched out of portals created by Jason's Darkness at his discretion, moving at high velocities, and with the object's mass being heavily compacted.  The smaller size without a decrease in mass, combined with the immense speed the objects will move at, makes an object incredibly dangerous to be struck by.  Something as large as a small house could've been compacted into a something the size of a brick, and could crush an Adamantine shield like a bullet through a glass pain.  A strong enough surge of magical power from his opponent will allow a human target to escape this spell's power, but not before being subjected to at least a few seconds of this spell's immense power.
 * Second Variation: Jason can also use a more intense and powerful variation, just on a smaller scale initially. This variation involves Jason creating a miniature black hole in between his hands, which then serves to such his targets in towards him.  Any matter this spell does absorb, including air and other gases, is immediately added to this spell's power, gradually increasing its size and gravitational effect over time.  Unlike the first variation, Jason is unable to summon forth any material sucked inside, as it is broken down completely into pure energy.  The only way for this spell to be stopped is for it to either be overwhelmed by a strong enough surge of power, or to be dispersed by Jason himself.  In the latter method, the energy absorbed can implemented into anther one of Jason's spells.
 * Quasar: A spell created by Jason by combining the aspects of Darkness Magic and Gravity Magic. He creates a spherical black hole in his cupped hands that sucks in everything that can't escape, taking a similar stance as Grimoire Law, though without any of the same effects. This gravitational pull is similar to that of an actual black hole, dragging in a great deal of material, despite the black hole phase of this spell only lasting for a few seconds.  After absorbing enough materials at a fast enough pace, the black hole then fires a blast of pure energy at his target.  The blast is incredibly hot and fast, burning anyone and anything that attempts to block it, and exceeding the speed of Light Magic.  As stated before, this spell can also implement power from Jason's Black Vortex: Second Variation, allowing Jason to cast the actual Quasar much faster, without the few second time limit for the charging portion, and giving it overall more speed and power.  This is Jason's most powerful spell, but due to the dangerous nature of the spell, and the high amount of magic power it requires to cast in the first place (either externally or internally), he generally uses it as a last resort.  This spell's power was so great, that without his Dark Eyes, it took the combined power of Seraph Kinmichi, Theia Zhulong, Chase Grimsted, Sykushi Strykri, and Kyshira Rytika to overpower it.


 * 4500mm Black Cannon: Jason holds out his hand, his fingers making a somewhat clawed shaped, and collects a large amount of Darkness Magic in it. He then fires a large beam of his magical energy at his opponent, large enough to encompass an entire person's body with plenty of room to spare. Upon contact with his target, it can either generate a powerful explosion, or remain blunt and continuously crush whatever Jason fires this spell at. One blast from this spell is capable of defeating an S-Class level Mage. It is capable of rendering most opposition unconscious. This spell managed to briefly knock unconscious Seraph Kinmichi while he was using his Iron Dragon's Scales. This spell, and all its derivatives, have the most killing potential out of all of Jason's Darkness Magic spells, and are considered his strongest series of spells.
 * 9000mm Black Cannon: A variation of the 4500mm Black Cannon where Jason uses both his hands.  He cups both his hands together and gathers Darkness Magic inside them. He then fires a large amount of Darkness Magic at his opponent. This move can also be performed one-handed when Jason's Dark Eyes are active. This spell is twice as powerful, and twice as large as the 4500mm Black Cannon, possessing the same effects but with a much greater impact. It is capable of matching Luke Gandor's Crimson Lotus: Dragon King's Charged Shell, which is the latter's most powerful spell.
 * 18000mm Black Cannon: A variation of the 4500mm Black Cannon where Jason uses both hands and has his Dark Eyes active. Preformed like the 9000mm Black Cannon is normally, he collects a large amount of Darkness Magic in his hands and fires a large stream of Darkness Magic at his opponent. Although, this move takes longer to perform than the 9000mm Black Cannon. Jason has described it as his most powerful weapon, before mastering his Dark Transformation. It is twice as powerful and twice as large as the 9000mm Black Cannon, which means it's also four times as strong and as large as the 4500mm Black Cannon, while possessing the same effects, but with a much greater impact. This spell can also be performed one-handed when his Dark Transformation is active.
 * 36000mm Black Cannon: A variation of the 4500mm Black Cannon wherein Jason has his Dark Transformation active and uses both hands. Like the standard 9000mm Black Cannon, Jason cups both his hands together and gathers Darknes Magic inside them. He then fires a large amount of Darkness Magic at his opponent. This spell is twice as powerful, and twice as large as the 18000mm Black Cannon, while possessing the same effects, but with a much greater impact. It is the strongest spell utilized by Jason, even exceeding the Formula 100 Amaterasu seal.

Amaterasu: By creating Magic formulas in the air, the targeted area is engulfed by a massive spherical shockwave. Jason's skill with this magic doesn't require him to always use hand seals, but he does require them for more powerful spells. Jason's casting speed with his hand signs is also unprecedented, being capable of creating powerful seals with little effort, and so fast that his hands appear as a blur. Individuals have compared his skill in this magic to Hades himself, and Drake Doomkaiser has stated that his skill in this magic is unmatched. The damage of such Magic increases with the formula's number: the higher the number is, the higher the consequent of damage is dealt. With one casual Amaterasu blast, Jason was able to destroy an entire dark guild hall and kill every member inside it, except for the critically injured guild master. He has access to the Amaterasu seals 1 to 100. Jason has the distinction of being able to layer his Amaterasu blasts, creating multiple shockwaves of increasing power and magnitude that consecutively strike his target. The resulting explosions cause immense damage to the target, and is also known to cause numbness and completely drain the stamina of mages that attempt to defend against it. Although the effect of the spell is dependent on the power of the Mage, as Laxus Dreyar was still capable of continuing the fight for some time after he was struck by Hades' Amaterasu. Jason can also not be affected by the power of his own Amaterasu formulas. Chain Magic: This Magic allows Jason to shoot long chains from his hands, complete with grappling hooks at the ends. They can be used in combat by launching the grappling hooks through enemies. After they have been caught, enemies can also be slammed into objects. These chains can be broken however. The chains are capable of piercing through any defenses, magical or otherwise, as the chains bypass them by becoming intangible. The chains can not pierce through those who can otherwise become intangible themselves, however. Jason can create several chains at once, using them restrain multiple targets at once, or restraining a large target, such as a Giant or wyvern. He can also use one to wrap around several opponents at the same time. The chains are capable of automatically extending and shrinking according to Jason's will, giving him chains that effectively have infinite length. He uses this magic alongside Luke Gandor for special combination attacks, as he is also a skilled user of Chain Magic. Jason can also use this magic in conjunction with his Darkness or Barrier Magic to increase the power of the chains, and give them extra effects. The chains are also capable of turning solid, allowing Jason to pierce or wrap around his target without the normal harmless piercing of this spell. When like this, the chains are much denser, capable of cleanly cutting through a building, and blocking Adamantine sword swings. Through spinning the chains, Jason can even block magical attacks, and diffuse or reflect spells that are energy-based (such as fire, lightning, or pure magical energy).
 * Formula 0: This formula does not follow the normal numbering of Amaterasu formulas, as in, the higher the number the more powerful the seal. This makes sense considering the fact that this spell does not have the same abilities as an average Amaterasu formula. Jason creates a giant seal above his target. It then strikes his opponent with a beam of purple light. This beam does not exactly harm the target, instead draining them of their magical energy, and siphoning it off to Jason. It will continue until Jason breaks off the casting, the target leaves the area of effect, or if the target is completely drained of magical energy.
 * Formula 5: This is the most simple formula of Jason's Amaterasu spells. The only required hand movement is an upward movement made with his index and middle fingers on one hand.  This causes two magic seals to suddenly appear, one above and one below his target.  They then detonate, trapping the target in a seal of purple light that continuously bombards them.  This spell is mostly designed to induce pain and drain magical energy and stamina, with the spell itself not providing that much physical trauma.
 * Formula 15: A much more basic Amaterasu seal, that Jason only needs to activate by collecting magical energy on his fingers. The energy then forms two rotating Amaterasu seals that Jason then throws at his target. When they make contact with their target they deal a fair amount of explosive damage, sending whoever is struck by this spell flying backwards. This spell lacks the same power as other Amaterasu formulas, but in contrast is much faster to cast, and requires much less energy.
 * Formula 28: Jason makes a back and forth motion with his fingers, creating three seals in front of him. Jason then holds out his hand in front of him, causing the seals to shrink around his hand, and generate a massive cylindrical shockwave or explosion. This spell has a massive area of effect, but lacks the ability to properly destroy some barriers. This makes the spell effective to use on multiple opponents at once, but not against those that use certain variations of Barrier Magic. These barriers generally must be incredibly powerful, such as the Maximum Defense Seal.
 * Formula 64: Jason first makes several rapid pointing motions with his index and middle fingers, generating magical seals that surround his target, two float above them, and six float around their sides. They then set off a powerful explosion, generating a spherical shockwave inside the area of effect, and when strong enough, exiting the area in its entirety and damaging people near enough to the explosion.  This spell serves to heavily drain a target's physical stamina.  If the target can defend against it, protecting themselves will often heavily drain their magical reserves, almost to the point of zero.  Usually, the affected individual will still be able to fight normally, but over time, they will begin to feel the affects of this spell as their body becomes numb and they become unable to even stand.  It is essentially a drastically enhanced version of Formula 5.
 * Formula 100: In terms of sheer power, this is Jason's strongest individual Amaterasu Formula. Jason performs a hand pattern at an incredibly fast pace. After performing the pattern, he creates three Amaterasu Magic seals on each side of the target and two other Magic seals, one over the target and one under them. This then generates a massive spherical explosion that can take up the entire arena of the Domus Flau. This spell is so incredibly powerful that it can even overwhelm the defenses generated from the Maximum Defense Seals, and defeat mages on the level of guild masters. It's even more dangerous considering the fact that the main target is in the epicenter of the blast. It can also affect individuals not in the epicenter, as long as they are still in this spell's blast radius.
 * Cascading Seal: Formula 175: This spell is actually a combination of four different Amaterasu formulas, striking his opponent one after the other. All seals appear at once, completely surrounding the individual that Jason is targeting. First, Jason casts Formula 25. It strikes his target, testing their defenses, and seeing if they'll be able to counterattack. If his opponent has a powerful enough defense, this portion of the technique will normally be harmless against the target. Then, Jason casts Formula 50. Being twice as powerful as the first Formula, this spell generally which will overwhelm most defenses, but it still will not normally deal damage unless the target's defense was too weak in order to protect against all of the blast, or is otherwise unprepared. Next is Formula 75, which will deal a debilitating amount of damage to the target, possessing even more power than Formula 50, with 50 percent more power. Finally is Formula 100, designed to finish off the target. This final detonation has the same effects and level of power as the normal Formula 100. Each layer of seals strikes one after the other, dealing immense damage to the target(s). The bombardment of energy to his target is often so powerful, that it can completely overwhelm a target in blast, rendering them unconscious, and possibly even kill them. Jason normally reserves this technique for the strongest of Mages, as it is an even stronger seal combination than his standard Formula 100.


 * Chain Wrap: Jason binds his opponent with chains, restricting movement as well as allowing him to thrash them about. Unless the chains binding his opponent are broken then the victim will still be bound. These chains more so act as cuffs or ropes than anything else, and can be detached from Jason's hands or seals in order to be attached to something else. Jason could even hang an opponent with a chain wrapped around their neck, and attaching the chain to one of his barriers in midair. These chains have incredible binding power, being similar to steel in flexibility, but more similar to denser metals in terms of durability and strength.


 * Explosive Chain: Jason wraps his chains around his opponent, restricting their movement.  The chains then explode, dealing great damage to the opponent. Jason can wrap multiple people in one chain, and even tie them together before detonation. The damage is equivalent to that of one of Jason's Amaterasu: Formula 15 seals, which has an explosive yield powerful enough to send back an S-Class Mage, if not outright knock them out.
 * Chain Shock: Jason wraps his target, or targets with his chains. He then shocks them with a great deal of Darkness Magic. This spell can be used to shock normal individuals, or even weaker Mages into unconsciousness with just a brief jolt, or it continuously damage a target until they pass out or die. The latter technique is normally used on stronger opponents. Anyone who makes contact with the individual while they are being shocked will be shocked in turn as well, at least as long as they make contact with said individual. Jason can make this chain incredibly long, allowing him to ensnare multiple opponents. He can also pierce through his opponents as the chains normally can, and shock them that way instead.

Barrier Magic: Jason also employs Barrier Magic. This Magic allows him to erect nearly indestructible barriers, capable of blocking almost any attack, although the barriers can be broken when enough force or piercing power is expressed. Even with this weakness, there still must be a rather fair amount of piercing power in order to break through the barrier. The barrier is also powerful enough to still slow down the attacks that manage to pierce it, giving Jason an ample amount of time to dodge or counterattack, or simply decrease the power of the blow. The barriers are nearly invisible and can be used both offensively and defensively. Jason can move the barriers at will, erecting them fair distances away from his person, and moving ones he's already created into the path of new attacks. Jason is not limited to only one barrier at a time, however. They function by dispersing energy across their surface, and as such, they work best against spells based around spread damage, such as unfocused Fire and Lightning Magic, and can reflect light, giving him a defense against the Lunar Eclipse Eyes and the different variations of Light Magic. The barriers are so durable that they can withstand blows from a Giant. Jason can also create barriers beneath his feet in order for him to fly around like he's on a hoverboard, or seemingly walk on air. As Jason's magical energy is attuned to his barriers, he can also attach himself to his barriers. He is even capable of standing upside down on them. Anyone else, however, will slide or fall off, even allies. People can get a proper footing on a right side up barrier however. Jason generally makes sheet-like barriers, but is not limited to this. He can create barriers directly on his person or objects, acting as a second skin, or defensive skill. This makes Jason able to take hit after hit, without his opponent even knowing they're doing nothing to harm him.

Katsu: A speed of light magic used to heavily damage one's opponent. This is primarily used as a finisher as Jason needs the victim to be intimidated by him before he can use this spell. It's so powerful that a casual burst is capable of destroying entire guilds. This magic is so fast that it can't be seen by the naked eye. Although this spell has been implied by Hades to be capable of incinerating people, Jason is only capable of dealing debilitating burn damage, charring the skin, and possibly killing his opposition. Jason was proficient enough in the usage of this magic that he was able to teach it to another individual, Alexander Doomkaiser, and have him master it as well. As punishment, Jason once used a weaker version to almost kill the members of Team Hayley, the second strongest team in Black Void, intentionally holding back power so that they would not be outright killed by the blast. It also overwhelmed Zancrow during a friendly sparring session as children.

Unison Raid: An extremely powerful ability that allows two Mages to unite two kinds of Magic, similar in nature, together, thereby creating an even stronger attack. Although a seemingly difficult ability to master, Jason is easily capable of doing a Unison Raid, seemingly, whenever he wants to. Although, it is evident that whenever he activates one, he is fighting with someone close to him, or at least someone he respects. He is capable of performing Unison Raids with any member of the Spartoi, William Mercury, and Matthew Drakon. The fact that his Unison Raids are made from two individuals' magic power also decreases strain on the casters when used. Dark Transformation: Jason can assume an unknown transformation. His skin darkens to black and his hair flares upwards wildly. On his forehead emerges a thick, golden circle, flanked by three thin, gold-colored lines to its left and right, which diverge slightly before going down under his eyebrows to reach his eyes' top edges, and from their bottom go further down to his jawline, over his neck, and diagonally across his pectorals so as to reach his arms, then stretching across the front of both his arms, presumably connecting with the above-mentioned, normally dark-colored tattoo at least on his left arm. These markings all appear over his armor, as opposed to on his skin like with August (a Mage who uses a similar transformation). This transformation increases his power exponentially. If one did not fear his normal power, they are almost certain to fear his power in this state. His strength is no less than double that of his normal state, and so overwhelming that people are often unable to resist his might. It is this ability that marks Jason as the strongest member of the Spartoi, and one of the strongest Mages of Dragon Gunfire. Through this transformation, and it's weaker derivative the Dark Eyes, Jason gains access to several powerful Darkness Magic spells, each one incorporating the overall effects of Jason's standard Darkness Magic, but are augmented in functionality and power to a much greater degree. Master Hand to Hand Combatant: Despite his incredible magical power, Jason greatly trained in hand-to-hand combat, during his time with Grimoire Heart, and often relies heavily on it. He can easily fight on par with even the most powerful of martial artists, even without magic. He was even capable of temporarily fighting evenly with Aether Cade, a master hand to hand combatant, for some time before he activated his Dragon Force. Jason also has extensive knowledge of the human body, knowing the weaknesses of the body in both natural and physical terms. By striking pressure points, he is capable of completely shutting down functions, and even completely shut down magical abilities in his target either selectively or throughout the entire body.
 * Neutron Star: A combination of Matthew Drakon's Holy Sphere and Jason's Dark Star. Jason creates the sphere of concentrated Darkness Magic from his Dark Star in his hand. Matthew then surrounds it with the power from his Holy Sphere, causing it to glow a brilliant white. Jason then moves it forward from his hand, initially moving slowly. Matthew then uses his own energy to send it towards their target at blinding speeds. The spell will crush and diffuse any spell sent its way because of how dense it is. It'll then crush whoever or whatever it makes contact with before detonating it a spherical blast. The explosion however does not burn. Instead, it creates an increased gravitational field, which continues to crush whoever is caught in this spell's large field of influence.
 * Holy Barricade: A combination of Matthew Drakon's Holy Sphere and Jason's Barrier Magic. Unlike many Unison Raids, this is a defensive technique. Matthew creates a sphere using his Holy Elemental Magic in his cupped hands, which quickly expands in size. At the same time, Jason creates a Barrier sphere in his hands, which increases in size to match that of the Holy Sphere. The two spells then mix together, with the two mages crossing their arms together as the spheres burst open and mix, creating an immensely powerful, white barrier that can block even the most powerful of attacks. This spell possesses the Holy qualities of Matthew's Holy Sphere, alongside the incredible defensive strength of Jason's Barrier Magic. The Barrier can actually absorb the power of whatever technique is utilized on it, increasing the spell's power the more it is attacked. And those too powerful to absorb, more often than not, it can still refract the spell, greatly lessening its effects.
 * Black Heaven's Flash Cannon: A combination of Jason's 9000mm Black Cannon, or any of its other derivatives, and Matthew Drakon's Purgatory Dragon's Heaven's Flash. Jason collects his Darkness Magic in both hands, as he normally does with his 9000mm Black Cannon, while Matthew does the same with his Holy Flames, but instead of using his usual stance or charging stance, he matches that of Jason. The two energies mix together as they're charged, and the two fire a large blast of their combined power at their target. It appears as a blast of Darkness Magic, with Matthew's Holy Flames surrounding the Darkness. This spell has the combined burning abilities of Matthew's Purgatory Dragon's Heaven's Flash, and the crushing power of Jason's Black Cannon. This spell is so powerful that it can overwhelm two mages of equal caliber to this spell's creators almost effortlessly. The fact that it is made from two individuals' magic power also decreases strain when being used.
 * Dark Eyes: The precursor to Jason's full Dark Transformation. His eyes turn completely black, but will transform back to their normal color if Jason continues on to his full transformation. With this ability, Jason's magic increases a fair degree, but nowhere near the same level as Jason's full Dark Transformation. This skill also allows Jason to see magic in colors, allowing him to locate different kinds of magic, and distinguish the different variations of magic just through sight. He can even use this ability to see the Curse power of the Etherious, but it appears muddled, and Jason is unable to differentiate the ability that his opponent uses. Even when his full Dark Transformation is active, Jason is still capable of using this skill. As an extra ability, Jason is also unaffected by Illusion-based Magics when activating this state, even canceling out the fear induced by the Lunar Eclipse Eyes. He can use this ability in his full Dark Transformation as well.
 * Helm of Darkness: Jason transforms his body into darkness, and moves around the battlefield.  This makes his body intangible, and he can phase through anything, but in order to attack he must become solid again.  Even when someone uses an attack that can touch his darkness form, the malleability of his body still allows him to more easily avoid incoming attacks. He is even capable of changing the size of this form, even shrinking down, but he can not decrease weight. He can still increase it, however, with the aid of his Darkness Magic's incredible density. Jason can turn specific portions, or all of his body into darkness, allowing an attack to phase through his torso, but he can still grab or punch his target with either of his fists. Jason can only effectively manage this transformation when utilizing his Dark Eyes or Dark Transformation.
 * Night Watch: Jason can use this spell with either his Dark Eyes or Dark Transformation active. Jason locks onto his target's magical signature with the magic seeing aspect of his eyes. He then fires two, black, optical blasts from his eyes, capable of tracking his target. The beams move incredibly fast, even being capable of keeping up with, and chasing down, High Speed and Light Magic users. Sending off blasts or portions of one's magical energy is unable to trick this spell, as it only chases down the largest source of power. The only way to avoid this spell is discharge so much magical energy that they will no longer have the highest amount inside their body, but this would bring an individual to very low fatigue levels. This spell is capable of boring through enchanted steel, and even denser materials such as Adamantine and Black Steel. It only dissipates after its hit its target, or is blocked by a sufficient enough force, which is very difficult to create.
 * Spartoi: A Darkness Magic spell that Jason can only use this when using the full power of his Dark Transformation. It is a unique spell that he invented in order to emulate Hades' Living Magic, giving it a similar effect to the spell Nemesis, but not quite the same level of power. Jason creates tendrils of Darkness from his body which latch onto any debris, or other materials strewn across the ground. The tendrils then form golem-like creatures that run on Darkness Magic. They are capable of stretching their body to cut and ensnare their opponents, as well as fire concussive blasts of Darkness Magic. Their bodies are not very durable, easily capable of being broken apart, but they also can regenerate their damaged bodies, allowing them to continue their assault regardless of the level of damage inflicted upon them. They completely bend to Jason's will, and will attack relentlessly until their mission has been completed. Jason can also use the tendrils created to simply latch onto opponents without forming a creature, and can even use his different Darkness Magic spells from the tendrils by transforming them into limbs. The tendrils can, overall, just be used an offensive weapon instead of creating a golem. They can even be used to create duplicates of Jason, either utilizing the pure tendrils made from Darkness Magic, or the more golem-like variations. When Jason drops from his Dark Transformation, any creatures he created with this magic will disappear.

Expert Weapons Specialist: Jason can expertly wield the weapons he generates from his Darkness Magic. This includes, but is not limited to, swords, scythes, spears, and maces. He is also a master wielder of chains (as evidenced from his usage of Chain Magic), an expert marksman (as evidenced by his aim with his Black Bullet spell and all of it's derivatives), and a skilled swordsman (as evidenced by his usage of his Stygian Blade). Jason's weapons skills perfectly compliment his magical capabilities.

Immense Strength: Jason trained his body to nearly pure perfection in order to deal with opponents, without him needing to use immense magic power to avoid drawing too much attention to himself. He's incredibly strong being able to easily lift boulders with one hand, even without magic, and easily flail around fully grown humans, and Giants using the chains from his Chain Magic. He had enough strength to punch Alexander Doomkaiser into the ground with one attack, shattering the earth beneath him when he made contact. When using his Darkness Magic, his strength is even capable of keeping up with and surpassing that of Julius Kaizar (the physically strongest man in the world), Victor Crassus' Monster Soul transformation (which is in about the same strength range as Julius), and Largo's Ascension state (which put him above the strength of Julius). One punch from Jason can do more damage to his opponent than a barrage of punches from them.

Immense Durability: Jason is capable of taking large amounts of damage, even more than his former master Hades. He can even easily take the shockwaves and explosions generated from his own magic with little to no difficulty (although, he is generally unaffected by the damage of his own spells). When going to recruit Luke Gandor into Black Void, he withstood a multitude of attacks launched at him by the Dragon Slayer before finally launching his own counterattack. He was completely frozen by Victor Crassus' Snowflake Armor, and not only did he easily shatter the ice, he appeared completely unharmed and felt no discomfort from the experience. He managed to take a vast amount of punishment from both Sykushi and Kyshira, and a combined blast from those two, along with the Draconic Vanguard and still remain standing. It wasn't until after Odin struck him from behind that he was finally defeated. While battling Largo of the Legion Under the Black Sun (who was utilizing Ascension), Jason withstood the doll's initial onslaught, only showing a few bruises and panting before retaliated with his own full-force power.

Immense Speed: Jason is still exceptionally fast. He was able to kill multiple Mages with his Black Bullet before they knew he was threat, and do the same to Darius Xerxes, albeit non-lethally, before he could finish his sentence. He was also fast enough to react to the oncoming assault of Alexander Doomkaiser, punching him into the ground before he could launch an attack. By the time of Bellona Alliance War, Jason was fast enough to match Hyperion Lucifer, the Fastest Mage of Othrys, in terms of speed. This means that Jason is capable of moving no less than at light speed with assistance from his magic. He also managed to keep up with Largo, who's physical strength in Ascension made him immensely quick and strong. This speed combined with the already immense gravity of his magic allows for immense damage with only a few blows. He's capable of punching an opponent in the face that's behind him so fast, that to the naked eye it appears as if Jason just turned around, and his opponent flew backwards.

Immense Magic Power: Jason was already born with a vast amount of magic power. This high amount of power can be increased even more by his Nightingale Armor. His magic power is so high that it rivals that of even Hades himself, however Jason has not had enough time to completely master his power causing him to often expel too much magic, causing large amounts of collateral damage and civilian casualties. After training with Cronus Saturnalia, Jason's power increased even more, making him stronger than even the likes of Miriam Cade, the strongest Mage in Dragon Gunfire, putting him above guild ace level. His power is so vast that he managed to overpower Sykushi and Kyshira single-handedly using mostly magical blasts, temporarily knock Seraph Kinmichi unconscious in one attack, maintain his Dark Eyes for two minutes (despite Theia Zhulong nullifying his Eye Magic), and perform the Quasar spell and remain standing afterwards, despite the level of fatigue he had felt. He is even strong enough to fight evenly with Aether Cade, although he was overwhelmed when the later activated his Dragon Force. He downed Alexander Doomkaiser in one strike, one of the former S-Class Mages of Black Void, and one of the strongest mages of said guild; and defeated Hyperion Lucifer, the strongest mage of Othrys, during the Bellona Alliance War. By the time he had arrived at Othrys, before the Dragon Gunfire/Othrys War, Jason was already stronger than any individual member of the Six Titans of War. His power since then has only continued to grow. He was even capable of defeating the Legion Under the Black Sun commander, Largo, the fourth most powerful of the Legion commanders, during the war the army had started, while the doll was utilizing his Ascension. During the X805 Grand Magic Games, he boasted that he was the strongest member of Dragon Gunfire's team. Out of all the Spartoi, the power of his base state is considered superior to all individual members. Vincent Alvaro believes him to be on par with the Giants (the generals of the covert operations, paramilitary organization Gigantomachy), and that he could perhaps be a match for Silicon. He's stronger than Matthew Drakon, who has gained similar praise, being able to surpass his power using his base and Dark Eyes power, while Matthew was going all out with his Holy Flames active. His magical aura is black, and as he taps into more and more of his power the aura surrounding him becomes larger and larger. His aura also gives off an intimidating feeling, causing those affected to feel fear, and giving Jason an opening to use Katsu.

Equipment
Nightingale Armor: This magic armor is a one-of-a-kind black suit that increases one's magical power. Even though Jason's power was already extreme, this suit increases it even more. The suit is lightweight and durable being capable of taking several strong blows from even the strongest of attacks, while not decreasing his speed in the slightest. The armor also has its own regenerative factor. It has been damaged multiple times, but still repairs itself by taking in eternano from the surrounding area like a person would. This process takes time, but it will still repair itself. This suit has withstood a barrage of fire-based attacks and any other blunt or serrated attack from Matthew Drakon and Victor Crassus during sparring sessions. It has been compared to Black Steel in durability, even allowing Jason to block swords enhanced with magic using simply his armor-plated body. Even when damaged, as long as Jason has some portion of the suit intact, Jason will receive a power increase. However, the increase is still proportional to the amount of the suit that's still intact.

Trivia
Despite his cold nature he still desires true camaraderie.

Black Bullet is Jason's signature move.

The events of Chronicles of the Black Knight were removed after the author lost interest in the series and thought there wasn't enough character development. As such, Mephiles is no longer a part of his backstory.

Jason was the first character created by Black Dwarf Star on the wiki.

Out of all the characters representing Dragon Gunfire during the X805 Grand Magic Games, Jason was the only one that didn't wield a weapon created through magic.

Jason's stats are:
