The song is the theme of Diablo's first Purgatory Form, King of the Damned.
"The dark reigns supreme, The deepest nightmares lurk without fallacy, without illusion, for nightmares are always true.. they reflect our deepest fears, our deepest shadows... the thing that Lady Corruption feeds upon... that.. is why Diablo is the name for the greatest Nightmare among Numensapiens!!!"
- Night Reveler
"BOOOOOM!!!" Silver Lightning blasted apart the great doors of the wrecked and failing palace, as Mikoto, in full Dragon Lord Form, walked in, followed by Natsu and Nicole
"Alright!!" Mikoto growled. "DIABLO!!! SHOW YOURSELF!!! WHERE ARE YOU!!!"
The throne room was silent for a minute, then a terrible demonic chuckle filled the entire room, filling the place with deadly purpose, and darkness.
"You have come.. I thought it would be Dragneel alone that I would be fighting, but instead, you brought me the whole threesome!!"
Diablo rose from the great throne, having been shrouded in shadows so dark, that none could see him until he revealed himself.
"Elohim wants me to leave you alone until he get's a chance to fight you." said Diablo. "However, even he can't complain, if it was you who came searching for me, and not the other way around."
"Diablo Etwatia!!" Mikoto roared. "For crimes against our race.. both humans and gods alike, you are going to pay the price!!"
"Really!? You think that because you achieved Dragon Lord Form, that you are a match for me!?" said Diablo. "Foolish girl.. I am not like my subordinates.. you know that better then anybody!!"
"CUT THE CHIT CHAT!!" Natsu exclaimed, flames exploding from his scales and horns. "Let's just get to it!!"
Diablo Narrowed his molten eyes. "I have been waiting for this.. Mikoto Misaka.. For years... A chance for the both of us.. TO FIGHT ON EVEN TERMS!!!"
Diablo launched himself forward, dark molten energy enveloping his fist as Mikoto launched herself forward as well, her fist exploding with silver lightning.
As soon as the two attacks connected.. a massive shockwave shook the building, and the combined force of the two attacks completely and utterly destroyed the room, creating a gaping gap to the heavens, leaving noting but a wall of ruins of what used to be a throne room, with a glaring dawn sunlight lighting the place in an orange color.
Diablo and Mikoto leapt back from each other, and Mikoto grinned, her fangs sparking with electricity too. "Not so easy anymore.. am I?"
Diablo chuckled, then he let out a booming laugh that shook the entire ruins.
"Not a good sign." said Nicole, baring her claws at ready.
"GOOOOOD!!" Diablo roared. "NO HOLDING BACK!!! NO MORE DISTRACTIONS!!!
KING.. OF THE DAMNED!!!"
Music Starts.
The earth cried, the ruins screamed.. as the powerful aura exploded out of Diablo. And from it, the massive black, muscular horned and winged gargoyle-like demon with a burning skull in it's chest, strode forth from the depths of darkness.
Diablo gave off a massive flap with his wings, and a burning shockwave blew forth, sending Mikoto, Natsu, and Nicole flying.
Nicole gritted her teeth, regaining her footing by sending out ghostly tendrils from her finger tips, and rooting them to the ground.
"PHANTOM SCREAM!!!!!" Nicole opened her mouth, and a sonic blast combined with phantom-like energy exploded from her jaws. Pure irradiated fear.
Diablo thrust out a hand with incredible speed, throwing a giant sphere of dark magma at the Fear Blast, both moves colliding with unimaginable trembling god-like reckoning.
While this happened though, Mikoto and Natsu both took the opportunity to recover and dash to either side of Diablo, intending to attack while he was distracted.
"IRON FIST OF THE THUNDER DRAGON!!!"
"IRON FIST OF THE FIRE DRAGON!!!"
The two punches of flame and lightning smacked straight into Diablo's chin at the same time, sending the demon flying.
Diablo smashed to the earth with a booming earthquake, only to flip back onto his feet, then rise into the air, pointing both his hands down at Mikoto and Natsu. "DOWNPOUR OF THE DAMNED!!!"
A massive explosive beam of horrifying energy which seemed to have monstrous skulls screaming, embedded within it.. was sent slamming down into the group.
Mikoto got in front of Natsu and crossed her arms together. "SECRET ART!! SHIELD OF THE DRAGON MAIDEN!!!"
A large Chinese Dragon made of lightning appeared, circling it's long serpentine body around Mikoto, creating a powerful electromagnetic force that split the blast apart.
Mikoto then wove her hands around, letting the dragon move with her motions, and fly off her hand, before wrapping around Diablo's chest and exploding in a powerful sphere of silver energy.
The silver lightning exploded into the sky, blasting all the clouds apart just as Nicole and Natsu both spread their dragon wings and soared into the sky, putting their hands together.. combining their magic into a Unison Raid.
"FLAME SPIRIT OF THE DRAGON'S MIST!!"
Nicole and Natsu sent their hands hurtling down, and a ginormous dragon made out of purple flames, with a fanged sinister ghastly grin, laughed like a maniac, and charged down at Diablo.
Diablo spread his wings, and the mere shockwave from his wings was enough to destroy Mikoto's attack.
Diablo then held up both his hands, and the flaming ghost dragon smashed into his claws, as he held it at bay, then tore it apart with his bare hands.
Just as he tore the attack, a powerful lightning fist exploded into his chest.
Mikoto moved at mach speed, going in and out of view as she flashed all around Diablo, dealing a quick and heavy barrage of god-like attacks.
The force from the multiple punches and kicks were so incredible that stones and rubble began to levitate in the air due to incredible electromagnetic force.
All manner of metal began to shoot randomly into the sky, burning with magnetic chaos.
Mikoto then screamed and let out one ginormous electric punch into Diablo's face.
Diablo held up a hand, and grabbed Mikoto's burning electric fist before it could make contact.. and a giant explosive lightning blast radiated around the two as they fought.
"Impressive.. Most Impressive.." Diablo growled, right before he fired a massive demonic blast from his eyes right into Mikoto's chest, blasting her into the ground.. sending her barreling further and further into the ground, the crater getting larger and larger.
"OH NO YOU DON'T!!!" Natsu surrounded his scaly talons in flames and grabbed Diablo's wings from behind, wrenching his feet against the ground to gain leverage, as he pulled Diablo backwards.
Diablo fell backwards, his eyebeams now blasting straight into the sky as Mikoto rose from the molten crater, a hole in her shirt.
"Impressive?" Mikoto muttered. "Don't you go Darth Vader on me, that guy saw me in the middle of giving birth.. it's awkward to even remember that asthmatic cyborg."
Diablo stomped his foot, and a molten shockwave exploded out and sent Natsu skyrocketing as he pointed a finger at Mikoto, "DARK EMBLEM OF THE DAMNED!!!"
A massive beam of pure hellfire exploded from Diablo's finger..
Mikoto opened her mouth. "ROAR OF THE DRAGON LORD!!!"
Silver lightning collided with the blast, and a massive hurricane exploded into being, changing the weather of the entire city..
"You have indeed become strong." Diablo said. "Even as Fulguras, you never possessed as much power as you do now.."
Mikoto panted a little from the moves she had just exhausted. "Heh.. well, you've gotta fight hard right? In any case.. it isn't as if I haven't already won."
Diablo paused for a minute as Natsu and Nicole landed on either end to help Mikoto surround the demon.
"What do you mean?"
"You don't get it do you?" said Mikoto. "My guild has been slowly taking over your entire city from right under your nose. The Security, your military.. we've snuck in at different intervals, disabling them all gradually, until all that remained was your Numensapiens and the Spriggan 12.. however, we've also disabled all means of communications! You're in the dark now Diablo, Nobody's coming to help you!!"
Diablo laughed. "You don't think I didn't know what your plans were!? I didn't even bother to counter them!!"
"Wh-what!?" Nicole stammered. "WHY!?"
"Because.." Diablo clenched his fists, a burning aura exploding from him, and darkening the sun itself. "I knew.. I knew ever since I first met you as a human.. Fulguras.. I knew some day you would gain the power to face me..."
Diablo held his hands to the sky. "You and I.. we are two opposites on a coin.. Dravis, Asgawrath, they were powerful foes without a doubt! However, despite all that, there is one enmity that has always remained constant!
YOU AND ME!!! Light and Darkness.. we are two sides of the same coin!!! Mikoto Misaka!!!"
Mikoto glared at Diablo. "Two sides of the same coin eh? Well.. I actually can't argue with that.. we do seem to have a tendency to run into each other do we? But.."
Mikoto clenched her fists as silver lightning began to gather around her body. "Here's one difference between us... I don't just rely on my own power to see things through.. no.. I have friends!! No, not just friends.. FAMILY.!!!"
Mikoto's eyes turned bright with powerful reckoning as both Natsu and Nicole aimed their palms at Mikoto. "WE!!!.. ARE... FAIRY TAIL!!!!!!"
Natsu and Nicole both bathed Mikoto with their own magic energy as Mikoto charged up with her own energy, getting ready for her attack.
"HERE'S OUR SPECIAL UNISON RAID MOVE!!! ROAR OF THE GOD DRAGON!!!!"
Mikoto opened her mouth, and fired a massive golden blast of energy... and as the energy blast fired... for just a moment.. for just a slight second.. her skin turned from scales into a beautiful appearance.. with blue lightning bolt markings on her arms and face... and she wore a blue dress... a Numensapien's power shroud.
Diablo's eyes widened with shock for just a minute in hesitation. "F-Fulguras!?"
BOOOOOMMMMMMMMMMM!!!!" A powerful explosion, so incredible, that it was visible from space, shot into the sky, searing the very heavens..
Mikoto, back in her Dragon Lord form, no longer bearing the appearance of a Numensapien, fell to her knees, panting, blood staining her clothing due to injuring herself, as her Esper Nature did not allow her to use magic that wasn't her own.
Natsu and Nicole helped Mikoto to her feet, as her wounds began to close due to a regenerative aspect of her Dragon Lord power.
(Dragon Lords, all of them, have the ability to regenerate injuries as long as they aren't too serious. Injuries created by dark magic however, as well as by gods and Numensapiens, cannot be regenerated, and must heal normally.)
"Did... we beat him?" Nicole asked.
"Of course we did!!" Natsu yelled. "Not even that creep could survive that!"
"Heheheheheh.. HAHAHAHAHAHAHA!!!!!" Diablo's demonic laughter filled the air, he stepped out of the smoke.. his demonic body scarred, his wings frayed, and one of his horns had broken off. "NOT BAD!! Not bad at all!!"
"HE'S!?" Natsu stammered. "NO FREAKING WAY!!"
"At 100 percent of my full strength and peak, I am much different from what I was during the era of Dravis's prophecy!" said Diablo. "At this level of strength, I am even strong enough to hold my own against Nichts or Supremos.. however, in any case.. I am enjoying this fight... I think it's time.. I showed you the strength I've been holding back.. I shall show it to you... MY MOST POWERFUL PURGATORY FORM!!"
"Lord of the Damned?" Mikoto growled, wiping some blood away from her shoulder. "That one you used against Beleth!?"
"HAHAHAHAHAHAHAHAHA!" Diablo laughed again. "Tell me Mikoto Misaka, how many Purgatory Forms do Numensapiens have?"
"4.." said Mikoto. "Maximum.. that's how it is.."
"And.. can you tell me what I.. Rosario Etwatia... was famous for before I became Diablo?" said Diablo.
Mikoto suddenly began to tremble.. her dragonish eyes widening in fear.. "No.. you.. can't still have that.. not after Corruption got you!!.. NO!"
"Mikoto! What's wrong!?" Nicole exclaimed.
"A-a fifth Purgatory Form.." Mikoto whispered. "I remember.. from when I was Fulguras.. Mom would tell me stories.."
"Mommy?" The little toddler Fulguras asked. "Whose the strongest one on our planet?"
"Well isn't it obvious?" said Amor, looking up from her cooking. "Supremos is."
I mean besides him!" said Fulguras. "I wanna know!! I bet Coluber 20 ros (Numensapien Currency) that Uncle Nichts was nowhere near as strong as you Mommy!"
A sweatdrop went down Amor's forehead. "W-well.. eh.. actually, Nichts is much stronger then me Fulgy. But.. if you want to know whose strongest other then Nichts.. I'd say it would have to be Rosario! He had a 5th Purgatory Form.
"A FIFTH!?' said Fulguras excitedly, her eyes sparkling.
"It was a legendary form called Emperor of the Righteous Seal.." said Amor. "You know how Uncle Prankster's 3rd form doesn't have a Purgatory God right? Emperor of the Righteous Seal is like that too.. it's so powerful that the Purgatory God's power was permanently absorbed into the form.."
"WOW!! I WANNA SEE IT MOMMY!" Fulguras exclaimed, jumping up and down.
"We.. can't see it dear.." Amor looked away sadly. "I'm.. not even sure it still exists anymore.."
Mikoto gritted her teeth. "YOU'RE BLUFFING!! YOU CAN'T STILL HAVE EMPEROR OF THE RIGHTEOUS SEAL!!"
"No.. I don't." said Diablo. "All my forms ever since my transformation to Diablo.. have been altered by the powers of Corruption.. you're right... I don't have Emperor of the Righteous Path... however.."
Diablo chuckled. "I still have... EMPEROR OF THE DAMNED!!!!"
Silence suddenly pressed down on the world... as the clouds blew apart.. and from the sky.. a massive shadow the size of a mountain fell down upon Diablo..
The shadows raged growing massive.. swirling around... burning the earth.. charring the sky.. spreading fear.. terror.. and abomination..
The entire continent shook.. the desert trembled.. the forests screamed out in pain... and in the sky.. horrifying faces laughed and jeered at the those who dwelled below...
The shadows blasted apart.. and.. there it stood.. the most terrifying, and perhaps deadly, Purgatory Form in all of the surviving Numensapien Race.
It rose.. a tall shadow.. darker then Nichts.. more frightening then Twilight Prankster.. more insane then Midnight Madcap...
It wore a dark hooded robe. The hood covered whatever face that might lay beneath completely, except for two red glowing eyes in the darkness... it was tall, very tall, and and thin.. the shredded robes hung like terrible rags upon it's form.
It's arms were the only things not robed, being covered in black bandages instead.. with claws coming from it's bandaged fingers.. long and dagger-like..
From under it's hood, two long curved horns extended out vertically, long demon's horns like that of an antelope.
The three headed Oriboris symbol of Hydra Head burned upon his chest.. now completely now of blazing evil flames.
When Diablo spoke.. his very words shook the foundations of the heavens. "Prepare... to die.. Mikoto Misaka.."
