Sneak Peak of a Overlord X Fairy Tail story I am considering

It is basically as it said when I was in the mood for Fairy Tail. I wrote the best scene I wanted to write. The scene here is a little rough around the edges though, so bear with me on this one. The title of this scene is Undead King Vs Dragon King.

Also, check out One-Punch DxD: Neo. I am co-writing the story out of pure interest.

Hell’s Valley, once home to an civilization that worshipped plants and nature, was a wasteland due to the change of climate over time. It was the location where the original founders of Fairy Tail searched for the legendary rainbow flower and looted the ancient ruins of said civilization, a land of precious memories for the first founder.

But now, the bone pale, polluted land sponsored a duel between two powerful beings that transcended mortal limitations. One, an entity summoned by the Black Wizard, empowered to kill anything. The other, the man responsible for the near extinction of the famous dragon race, and consequently became one as well, presenting himself before his opponent in his most iconic form.

“Well, you look like an extraordinary specimen. I wonder, how strong are you compared to those I’ve slain in the past…” he mused to himself as two crimson lights flared in his sockets.

Acnologia, the great clamilty, noticed the small man before him. The magic power impressive for one so small, the taste richer than even most dragons he’d slain, perhaps the richest, but it was… different somehow. He can smell the stench of dragon and something demonic, but behind them was something truly foreign. Regardless, the thought of a decent fight sparked in his head as he turned to focus on the man. What could this new creature show him?

“Not much of a talker, are you?” Momonga mused before holding an hourglass in his hand, one radiating something peculiar.

“I don’t address lesser life forms,” Acnologia said.

“Hoh, so the rumors were true. Well then…” He broke the magic item in his hand, an act that confused the great dragon king.

“I wonder if you can withstand this. Penetrate up.” He casted the penetration buff on himself as he casted the next spell.

The dragon was curious. What was this magic? It tasted… foreign. Even more so compared to the other Magics he encountered in his long life. It felt more… mechanical than biological in nature. Something truly artificial.

“Super Tier Magic! Heaven’s Downfall!” 

From the limitless heavens, overwhelming light dawned upon Hell’s Valley, purifying the land and everything on it with deluging white. The land charred under the heavenly light, searing even the ‘invincible dragon’s’ flesh beneath the scales.

The land of polluted white was scarred, the wound a burning crater where the ground was onyx black and glowing white, the only two survivors being the caster and the humbled king.

Acnologia felt something that he had nearly forgotten for the first time in his long years. Pain. The feeling excited him. Here was a phenomena he once thought impossible. Someone injuring him with magic.

“Hm. Your durability is irksome.” Momonga grimaced begins his featureless skull. Normally, he would scour the opponent of his strengths and weaknesses, gather information of a surefire victory. But this was not a fight entirely fueled by logic. He came here on pure emotion, to not only avenge the ones that treated him as comrades but also to fight against his very nature. To preserve his humanity, no, to defeat the thing threatening to consume his humanity.

His skeletal fingers tightened around the serpentine staff of his Guild Weapon, the only thing he had in memory of Ainz Ooal Gown. He cannot afford to fight even more recklessly than this. He must put everything he has on the line and more if he wish to win this PvP. It was time to test the limits of this Dragon King.

“Ahahaha haha! Amusing! You have gained my acknowledgement, stranger!” The Dragon King declared as he landed, his flesh shrinking compressed, his shape reformed from beast to human.

Momonga watched as the being known as Acnologia presented himself in his birth flesh, his true face underneath all those scales as he flashed the undead a fierce, toothy smile.

Before Acnologia could respond, another bolt of magic appeared out of the blue, smashing his skull with uncanny precision without warning, and with the force of a meteor. No, Acnologia corrected himself. Somehow, the man of bones conjured a meteor onto him with full force without his knowing.

Not only, all heat escaped his body, his spirit marred by hands of black almost simultaneously with the hammering meteor. As if something was trying to depart his spirit from the mortal coil by force with its piercing hands.

“AHHHHhhhhhhhhhh!” Within the crater, Acnologia screamed from the alien pain, the experience unlike what he usually experienced, a power not even the dragons could inflict during his epoch.

“Ahhahahah!” the cry of pain turned to peals of laughter. “Finally! An opponent worth fighting!”

“I've fought stronger.” Momonga taunted upon remembering Touch Me.

Acnologia shot out of the crater and speed towards the cocky mage. Fist wreathed in magic power. 

Immediately, Momonga casted another spell.

“Wall of Skeleton!”  

Immediately, a wall of skeletal warriors erected from the ground, interposing Acnologia’s path as countless conglomerated undead raised their arms against the dragon.

The undead bodies scattered like dust as he passed through them, his speed unhindered by the army.

“Ars Moriendi! Chains of Malice!” Immediately, chains from Momonga’s robes appeared, flowing in swarms as they zipped through and impacted Acnologia’s, wrapping around him.

However, unlike with Yggdrasil magic, it turned in to pure energy and was swallowed by the foe.

“What strange magic is this?! Tastes,” he paused for a bit, “bitter.” The fearsome dragon slayer’s face contorted into one of disgust. There was no such thing as bitter magic as far as he knew, all magic should bear palatable flavors, but something mixed with the magic seemed to upset his gut for the first time. “This will take some getting used to.”

‘Nullification?!’ Momonga tested his newfound magics at the wrong time, confirming the effectiveness of both Yggdrasil and Earthland magic at a cost. Although, his experiment with negative energy confirmed its effectiveness against the Dragon King.

“I see you've glimpsed the sample of death. Would you like another?” Momonga asked before casting his next spell.

“Boosted Magic: Negative Burst!” He shouted, as from his being exploded a expanding sphere of unliving power, blanketing Acnologia in the same bitterness, but in a much purer state than prior.

However, before Acnologia could reach the skeleton, Momonga was no longer there, no trace of magic or anything whatsoever.

And before he could speak his next word, replacing his foe, was a glowing sphere of energy.

“Maximize Boosted Magic: Exploding Mine.” 

After speaking from far behind Acnologia, the sphere of magic exploded in Acnologia’s face, inflicting further damage before he could react, but not consume. Some arcane remnants drifted in the air, smaller than he would’ve liked but suitable enough.

Opening his mouth, Acnologia proceeded to drain the fumes of the arcane bomb, finding the taste exquisite. The disgusting thing that dawned upon his tongue left his dish this time, used up upon impact.

Acnologia spun around, facing Momonga’s magic signature. As he raised his fist, a bright light burst forth from the ground beneath his target. The land exploded in a column of magic energy, sending rocks hailing down.

“!” 

Momonga’s two passives, both of which negated magic and physical damage of a certain range, only worked upon attacks sixty level or lower or sixth tier magic and below. However, ever since his time here, he could feel his passive much stronger than usual, and the Staff of Ainz Ooal Gown amplified his racial skills as well.

However, his instincts warned him of great danger, causing him to conjure his magic barrier the instant the man raised his fist. He looked down at the bottomless pit the dragon created, as the seemingly unending blackness stared back.

When he looked up to face his foe, he found him charging right at him. Acnologia’s clenched fist striking at the necromancer. His punch made contact with the barrier and sent Momonga rocketing back. The barrier broken, but not completely.

“Nnnn!” Even with the Staff of Ainz Ooal Gown, the monster could match him. Gritting his teeth and fang, Momonga prepared his counter as Acnologia closed in again.

“Maximize Magic: Reality Slash!” 

He responded Acnologia’s aggression with a swipe of his free hand, firing a literal cleave of sundered space-time. As it connected to the king’s body, Momonga realized something. The man didn't bothered to dodge. No, he wanted to experience his spell. 

Acnologia’s chest burst crimson from the clean slash of space-time, blood spurting out. But he didn’t slow down. “This magic is strange, but I think I’m getting the hang of it.”

“Maximize Magic: Implosion!” 

Acnologia fell to the ground, coughing blood from the sensation of something crushing his innards. His eyes turning from playfully cruel, to deadly.

“Fly! Greater Hardening! Draconic Power! Greater Full Potential!” Momonga levitated in the air, casting three buffs on himself during the respite.

“Mana Essence!” This spell allows him to identify his target’s MP, or magic power in Earthland’s case. However, he narrowed his nonexistent brows, seeing a greater amount of magic power than he thought. It was almost comparable to that of a high tier Raid Boss, the kind that can cast as much skills and spells as they want.

“Magic Boost! Paranormal Intuition! Magic Caster’s Blessing! Absorption! Heavenly Aura!”

Acnologia lifted himself to his knees, staring at the floating man. First gritting his teeth, then curling his lips into a smile. Taking a deep breath, he roared. The magic beam burst from his mouth in a blinding flash, unerringly heading towards the first worthy opponent he engaged in a long time.

“Maximize: Ars Moriendi!” Momonga threw a palm forward, hoping that it could negate or lessen the beam.

“Charnel Mantle!” A cloak of black, translucent and ethereal, shrouded Momonga’s regal frame. It was a move designed to negate attacks laced with killing intent, though he wasn't sure if it could be overpowered so far given the opponents he faced until now. 

The beam collided with the tranquil black, vanishing at the moment of contact which surprised both Acnologia and Momonga. The first surprised that his invincible beam was fended off, the latter more surprised that it failed to completely negate it as some penetrated through his defense. The only reward from this exchange was the knowledge that he could mitigate his opponent’s moves.

Acnologia narrowed his eyes, he’s never seen his dragon’s roar so easily nullified. But this just added fuel to his rage.

“I will destroy you, dark wizard.” He vowed. With that, he flew up to the wizard and sent a wave of magic at him with a swipe of his hand.

The dark wizard vanished again, escaping Acnologia’s ensnaring sight, the wave of magic power passing through empty air into the distance until it sundered the clouds aside.

“Where are you?” Acnologia sniffed, turning to the direction of the skeleton’s magic, but saw only the empty sky and the singed horizon.

Momonga turned invisible with Perfect Unknowable, a spell that grants invisibility and silences his voice. He raised his hand at Acnologia and channeled his favorite Spell, speaking within the shroud of silence.

“Maximize Penetrate Magic: Grasp Heart!” He clenched his bony fingers as hard as he could, trying to crush Acnologia’s heart in his hands from afar.

Acnologia’s hand went to his chest, nearly mirroring Momonga’s actions. The pain made him plummet to the ground. It was even worse than before. His heart struggling to keep beating his lifeblood. But the heart grew stronger with each beat, and for the second time today, he rose again from his knees.

Looking up, the Dragon King saw three blades of obsidian flying towards him, flying so fast and so close during his respite.

With great effort, he flung himself aside, the blades slicing his skin neatly, yet shallowly. Rolling onto his feet, he flew at the unseen wizard suspended in the air.

“I know you're there!” Acnologia roared as he readied to tear the wizard’s bones apart. While he can't see him, he can sense his magic power, and his senses never failed him when it came to magic itself.

The moment he closed in enough, the undead canceled his Perfect Unknowable, with his hand so close to Acnologia holding a black sphere of energy at point blank. 

“Maximize Boosted Magic: Gravity Maelstrom!” He shouted, firing the black sphere of chaotic force at the Dragon King’s face, sending him back down to the Earth, but not without Acnologia grinning through the damaging pain as he sucked the remnants of the powerful spell and significantly replenished his reserves.

“Get down here!” Acnologia cried as he pointed to the air above the wizard. There was a glowing like before, but instead of the ground shaking, the air rippled with heat. The blast of magic power shot downwards, blasting the wizard to the earth.

His barrier still held, thanks to the reinforcement he did while the dragon was recovering from his previous attack. Momonga suspected Acnologia would try something like this.

As the magic power cleared, Momonga looked up to see the fist of Acnologia connect again with the barrier. This time the barrier broke, but before the crazed dragon could do anything else, he vanished without warning again.

This time, he was surrounded by more of the explosive magic mines around him.

“[Triplet Maximize Boosted Magic! Thousand Bone Lance!]” Momonga shouted as, from the earth, erupted a ring countless spears of bones surrounding Acnologia in their center. The dragon widened his eyes and gritted his teeth, about to open his mouth to eat the magic bombs while they exploded and the bone lances closed into his being like teeth from a giant circular maw clamping onto its prey.

A brilliant explosion erupted, though some of the brilliance sucked into Acnologia’s maw like a black hole sucking in light, but not without difficulty as he endured literally thousands of bone lances pelting his hide.

“Eternal Flare!” Beams of light shot forth from behind Acnologia, many aiming towards Momonga, but most firing in random directions. There were great explosions when the light made contact with the earth. Momonga, weaving around the dangerous the blasts, was caught off guard by the dragon slayer who herded the wizard right towards him.

Zipping in faster than Momonga can blink, Acnologia grabbed the wizard by the robes. Clutching fine threads seemingly entwined from the fabric of the night sky itself, he threw him to the ground so hard Momonga bounced from the impact. As he descended the second time, Acnologia stomped on directly into the red orb. The strength from the blow pounded the ground to rubble and covered the skeleton with dirt so only his white skull and arms were visible. With a vicious kick, he knocked the most prized possession out of Momonga’s hands: The Staff of Ainz Ooal Gown.

“!” Weakened without it, Momonga immediately released the sealed spell.

“Release: Triplet Maximize Boosted Magic: Magic Arrow!” Momonga released the spell he stored for use as three magic circles appeared, one above, one at his left and the other right.

“Hm!?” Taken aback, Acnologia opened his mouth to fire his breath at the pinned skeleton, but the undead’s hands grabbed his ankles as the accursed blight entered his being, the unknown, foul energy sapping his strength before he could exert it.

Erupting from the three circles, a fusillade of arcane bolts pelted his hide with the force of cannons, flinging him off in the air in an almost unending barrage. Immediately, Momonga flew to his staff, gripping the recurved golden handle before widening his distance from the Raid Boss.

Acnologia landed on his feet, smoke drifting from his body showing the power behind the magic attacks. After taking a deep breath, he sent a torrent of destructive magic towards the empowered foe.

Facing the radiant stream of destruction searing the air towards him, Momonga grimaced as he conjured a Death Knight before him. 

“Middle Tier Summon: Death Knight!” 

Emerging from his essence of undeath, a black, hulking monstrosity formed from the essence of violence and brutality bedecked in heavy plated armor forged from the foulest abyss with red lines streaking across it like crimson veins, the undead raised its decaying pavisse to defend its creator before it engulfed it in a radiant light. Another explosion erupted, one not of fire and smoke, but pure ethereal might, drowning the landscape and further in pallid light while rearranging the land - cracks spreading further from the battlezone.

However, once it died down, the Death Knight remained standing, albeit barely. Its armor fallen apart, its flamberg snapped from the base and its pavisse cracked with shards dropping off, but it still stood, fulfilling his duty as its master’s shield. The sight earned more genuine astonishment from the Dragon King.

He grit his teeth in frustration. “How many tricks do you have?”

Behind his summon, Momonga looked up. Acnologia could not tell from his stoic visage, but he could somehow discern his foe was grinning with mocking despite his face possessing no flesh.

“Don't know. Care to find out?” He taunted, wagging his skeletal finger at Acnologia to come at him.

Eyes bloodshot with rage, he exploded forward with the fury of a thousand dragons. The remains of the Death Knight rained on the landscape as Acnologia tore through it on his path towards the insolent creature. 

In response, Momonga silently casted teleport, appearing far away atop the ledge of the crater of Heaven’s Downfall as he retrieved another item from his inventory. 

“Have another taste!” 

Momonga pondered what other tricks he had. He had Crypt Lords who can also summon Death Knights, he had pale riders, he had other spells but he prefer to not cast ones that last since it will only serve to feed the Raid Boss.

His newly acquired magics was somewhat useless against the dragon, thus he decided to end it as soon as he could. He had no idea how high Acnologia’s health was, but he might reach the endpoint now.

Crushing the hourglass in his hands again, Momonga casted Heaven’s Downfall again as Acnologia recurved his trajectory towards him.

“Heaven’s Downfall!” From the heavens, the same searing white descended upon them like Etherion shot from the stars, engulfing Acnologia in the same white world once again.

“Don’t mind if I do!” Prepared, The Dragon King shouted as he swallowed that white world. The spell might have failed to harm the dragon, and it might have even allowed him to regain power, but it did stop him in his tracks which provided the clever wizard precious time to conceive another devious plan.

“Just how much you can eat…” 

Momonga experimented with his own Slayer element. He could consume the damage of others, mostly from other living beings or decaying corpses, meaning he could somehow ‘heal’ others by consuming their damage. He might also be able to consume other Instant Death or Necromantic spells and skills as well, but he never encountered those types in his travels.

He could devour corpses, though not in the traditional sense. If he ‘consumes’ a corpse, or any rotting or decaying material, metal included, it will completely fade to dust. It is like him sucking the vestiges of the vessel’s hold on existence rather than directly consuming the solid material. It was a strange type of element devouring in his opinion.

He tried devouring his summons, but failed. It turned out anything he conjured up was a part of him, so that was out of the picture. He couldn't even devour the summons of his summons, which was completely bull**** on that part. He almost found a way to cheat the Slayer rule.

However, he could consume the summons conjured by items, or any other item with the Death Element, which still sucked. He still has the Horns of the Goblin Generals to feed on, but he cannot eat the corpses of those HE or his skill-based summons killed, which was even more bull****.

Even so, he felt… somewhat felt stronger for some reason despite the pulsing pain echoing through his bones. He ignored this feeling, not minding it, but Acnologia discerned it instead. He can feel the undead’s power growing stronger.

“Have a taste!” Throwing Momonga’s quip back twofold, Acnologia howled with laughter as a deadly rush of magic spewed from his mouth. 

“Widen Magic: Gate!” Immediately, Momonga executed his backup plan. Knowing that any breath attack will be empowered if consuming the element, and that the slayer can't eat his or her own attacks, he had this coming for Acnologia a long way.

Before him, a dark tear ripped open, as if someone pushed apart the thin veil of reality aside, revealing an unknowing darkness within. The moment it made contact, the raging stream empowered by Momonga’s super tier spell vanished within the darkness, reappearing behind the Dragon King.

The super-tier empowered attack struck him faster than the dragon king could react. 

“AHHHHHHHHHHHHHHH!!!!” In a cruel irony, his spine recurved from the force, Acnologia screamed with rage in his soaring flight towards the Stygian rift. 

Looping back through the same Gate, the Gate closed off allowed Acnologia to see Momonga’s retreating his distance and casting his next spell.

“Triplet Maximize Magic: Reality Slash!” In addition, Momonga threw twice more blades of severed space-time with three swipes of his arms before vanishing again.

The blades streaked bloody lines, deep scars atop of the ones he acquired centuries ago, as he screamed in pain before he crashed into the nearby mountain that toppled atop of him like a massive jenga tower.

Acnologia emerged from the fallen mountain, not as a man, but in the terrifying form of a dragon, while the bleeding wounds from the battle still remained.

“Enough games! Behold, my-” he roared before he was cut off by the same meteor crashing atop of his skull point blank - sending him back under the rubble and tallying another insult to injury. 

“RAHHHHHHHHHHHHHHHH!!!!”

The mountain exploded from materialized fury. Spying the perpetrator, he attacked.

“Eternal Flare!” Thousands of those deadly beams of light shot out from his wings, bombarding the valley with their destructive power.

However, the undead teleported again, appearing a mile behind the dragon this time as he pondered how to deal with the dragon version.

From his experience with Raid Bosses, the final form was the hardest in general. The mere flashback to those hellish days with his guildmates pulled a fond smile, but then a frown upon remembering that dying here meant dying for real.

He decided to test out his dragonic capabilities with his summons.

“Summon!” He called upon the Staff of Ainz Ooal Gown, summoning all seven Primal Elementals, from Fire to Water to Star, the last one being level ninety. 

He proceeded to empower them with as much of his spells as he could before the Raid Boss turned around, circling around to face the insolent mage.

Between him and his prey were seven polychromatic colors closing in to intercept him, but a wave of magic snuffed out those obstacles with barely a second thought. His whole being was focused on erasing the existence of the mage who challenged him, who mocked him and his power.

Within a single calm moment, Acnologia strained every fiber of his being and drew in his power. When that moment passed, he released it.

“Maximize Magic: Greater Magic Shield! Extend Maximize Magic: Charnel Mantle! Summon: Death Knight!” 

Immediately, Momonga shielded himself in an arcane barrier, the same shroud that negated the Dragon King’s breath and hid behind his sturdy summon before the Dragon King’s might enveloped the undead in the world of ethereal light.

Where there was once a valley and mountainside, only a crater remained. 

Destruction invaded the land as far as the eye could see, miles and miles around as if leaving a scar on the planet. The land was nothing more than a giant bowl, as if a great meteor crashed down above and bled the land. Magma and cracks bedecked the crust, the solid mantle visible from the surface around the epicenter.

Panting from overexertion, Acnologia reveled the sight of the remodeled landscape with cathartic fervor. He finally erased the enigmatic yet insolent mage from existence. He hoped that was enough to obliterate even the ash and dust of his corpse as well.

However… his smile reverse, shock and unfathomable fury marking its stoic features. 

Coughing from the ashes, his despicable foe rose from the epicenter of the charred rubble, still ‘alive’, or as alive as an undead can be.

“I must digress, that felt pitifully lukewarm in comparison.” He commented, mostly to rile up the dragon as he dusted the dirt from his robes.

Although, while he appeared to have survived the attack, in truth, he just teleported back from afar. The defenses he conjured were mostly for show while the Death Knight serve as his eyes via Undead Slave Sight after it survived the death beam. He admitted that he might have never survived should he tank that dragon nuke, and would probably die finding out. Hell, he even saw the lightshow all the way from Fiore, but at least he could inflict more damage with his words to the dragon’s pride than his spells to his hide.

Rage boiled within Acnologia like bubbling magma as Momonga casted his trump card. He hoped that Acnologia has no resurrection spells or other skills, or else he is screwed.

“The Goal of All Life is Death!” 

All of Acnologia’s blood ran cold at the mention, as if all heat fled his body toot sweet in absolute terror. His eyes automatically locked onto the arcane clock of ethereal gold appearing behind the wizard.

“Maximize Widen Magic: Cry of the Banshee!” 

Flinching, the dragon closed his eyes as the ear-piercing shriek assaulted the land and his sensitive ears hundreds of meters around, roaring in return. However, something happened. He did not feel himself resisting the spell, or negating it like usual. It felt as if… he was entombed inside a coffin prepared by death himself.

The clock hand ticked, the simple yet deceptive sound pulling a pulse from Acnologia’s heart. For once in his life, he felt fear. Fear of something unknown, the fear of death. He did not know why, but instincts screamed to kill the thing before him or else he will die. Something about this strange spell was alarming his instincts to its zenith, screaming at him to do something or else he will DIE.

The clock ticked again four more times, meaning Acnologia had to act fast. 

Roaring, Acnologia descended upon the undead ready to tear him apart between his teeth. However, before he could, he failed to notice the meteor falling down from the heavens - the cause being the shock and rage blinding him to the undead’s hidden plans.

The dragon was about to avoid the meteor this time, not wanting to endure the hit the third time, but something else affected him. A spell that tried to rip his soul from his vessel and drag him to the land after life, stunning him in place as he struggled to resist it with desperation, desperation he haven't felt since the Dragon King Festival.

The meteor struck, sending the dragon plummeting towards the ground. He landed in front of the smug wizard just as the clock struck twelve.

“For the lives of my friends you took: Sleep for eternity, King of Dragons.”
