Sorry for how long this chappy took, it took some planning to redesign Skodati. The music is Skodati's theme.

"RRRAAAAHHHHHHHHHHH!!!!!" Vasto Lorde Misaka smashed the ground with her fists again, using territorial intimidation similar to a Grizzly defending it's territory. With each repeated blow to the ground she made with her fists.. craters formed.. and magma seemed to erupt from cracks in the desolate terrain.

Grunk lumbered around and his mouth gaped open drooling. "Hmm.. she's.. interesting.. powerful.. but dark.. this should get rid of my boredom.. don't you think?"

"Oh how silly." said Jill.

"Yeah." said Vill. "A silly hollow stand against Numensapiens? That's relatively unheard of!!"

Diablo remained silent, studying the newly evolved Vasto Lorde with his molten eyes..

"I'll take care of this.." Grunk muttered. "Ahh.. what a drag.. I have to deal with a meager hollow."

Grunk lunged forward with his incredibly unstable speed.. running in an awkward frightening wild manner, slamming down his head at Vasto Lorde Misaka. But there was a flash of speed.. and the head slammed down on rubble instead as the hollow blitzed out of the way.

Vasto Lorde Mikoto reappeared behind Grunk, and her tail came down like a whip, wrapping around the Numensapien's neck. Before he knew it, Grunk was  being slammed from side to side, the giant tail repeatidly bashing him against the ground.

With each impact, a massive earthquake ensued, and giant petrified trees from the dead forest, tall as the sky, and each 50 times more massive then the Chrysler Building, crumbled to dust.

Vasto Lorde Misaka then threw Grunk into the air, and opened her jaws, firing a tremendous black electrically charged cero..

The entire sky turned black from the power.. obscuring the misty clouds, and creating an artificial night before the energy cleared, and Grunk fell to the earth like a molten meteor..

"Impossible Improbable!!!" Oculus exclaimed. "So many calculations I must analyze!! AMAZING!!!"

"Be amazed on your own time!" said Egnim. "That beast is nothing to Hydra Head!! The Elite Guard of Lord Diablo!! Vill, Jill!! You know the drill!!"

Vill and Jill both giggled as they joined hands..

"Time for us to show.." said Vill.

"Why we are the most vicious.." said Jill.

"Numensapiens alive." finished Vill.

The two girls both spoke at once, their voices becoming absolutely demonic. "Hell's Art: Dark Pain of the Hell Sisters..."

A massive  blast of darkness engulfed the two girls.. tremendous terror seemed to manifest itself from the very environment..

Vasto Lorde Misaka growled ferally, watching the darkness intently as black plasma drool dripped down from her jaws.

When the darkness cleared.. a most terrible horror stood in the place of the two girls.

It was a tall 30 ft humanoid.. with black skin made of a substance that was neither solid, liquid, or gas.. but something completely different.. long fingers held dagger-like claws, also completely pitch black. It's strange 'skin' was translucent, showing spiderwebs of blacker veins. It's pores secreted black liquid that hissed and sizzled as it dripped to the ground.. there were two female heads on it's shoulders. that looked malnourished, with blood red eyes and long gray hair.. their jaws were full of rotting sharp teeth. Imbedded in the creature's chest was large red eye with a slit for a pupil

"Prepare for death.. or dinner.. or both.. you know what? We're just going to eat you till you're dead!!!"

JillVill  moved like an undead super terror.. blitzing from side to side.. knashing her teeth over and over and over, leaving black spit in her wake. She engulfed her needle claws in black bloody liquid and slammed them down on the head of Vasto Lorde Misaka over and over and over..

The two headed monstrosity was so fast, that the Vasto Lorde didn't even have time to react as the earth blew apart from the repeated blows.

Vasto Lorde Misaka roared viciously and knocked aside one of JillVill's claws with her own beastly talons before surrounding herself in black plasma lightning and bashing straight into the creature's gut.

JillVill flew back over 20 miles as Vasto Lorde Misaka dashed after them on all fours, becoming faster and faster and faster and faster with every second she ran, her wings firing powerful blasts like booster rockets.

She then got in close, her claws trailing black lightning.

An uppercut talon slash, a powerful punch, and  a massive explosion of black plasma later.. but JillVill laughed in her demonic voice, grabbing both of Vasto Lorde Misaka's claws in her own.

"FOOL!!! YOUR FEAR AND TERROR AND RAGE!!! ALL OF THAT ONLY FEEDS US!!!!

JillVill opened her rotting gaping mouths.. and a black energy poured from them like liquid.. the pool of liquid spread for 13 miles.. growing wide and dark.. as it spilt upon the skin of the hollow.. and Mikoto began to sink into the darkness becoming fully submerged...

"This darkness shall consume your soul.. and erase you from existence.." said JillVill.. "You will be nothing.. as if you've never even walked on the face of this plane... Nothing can escape.."

"Well..  it was powerful.. I will admit.." said Oculus to Diablo as he watched from afar. "Much more powerful then an ordinary Hollow.. But in the end.. it can't hold a candle to Night Reveler's daughter.."

"Fool.." said Diablo. "That won't be enough.."

The giant pool of darkness began to seep away as the clawed hand of Vasto Lorde Misaka broke the surface of the great blackness..

"WHAT!?" said JillVill. "Impossible!!!!"

Vasto Lorde Misaka burst from the dark pool as more of the black pool poured into her jaws.. She.. was devouring the very darkness itself!!

"As I suspected.. that is no ordinary Hollow.." said Diablo. "An ordinary hollow could not defeat Aleister.. and ordinary hollow could not defeat Ulquiorra.. darkness feeds it.. strengthens it.. she is the Dark Railgun.. the dark side of Railgun.. the manifestation of her instinct, her rage, her fury, her predatory desires.. "

Vasto Lorde Misaka consumed the last of the pure liquid darkness and snarled.. black smoke billowed from her open jaws as the earth once more began to tremble, and her wings spread wide  intimidatingly before JillVill before opening her jaws and letting out a terrifying roar so vicious, that the entire planet shook.. yes, the entire planet..

"I will deal with this myself.." said Diablo, stomping forward.

"NO!!! MASTER!!! WE CAN KILL HER!!! WE CAN!!!" JillVill screamed wrenching the eyeball out of her chest. "COME!! FILL HER WITH FEAR!!! TARRANTULUS!!!!!"

The eye flew into the sky, becoming massive.. growing larger and larger as multiple giant spiderlegs sprouted out of the end, intertwining with guts and tentacles.. spiraling out and massing.. until there was a giant massive worm made out of veiny spider legs, burned darkness, slime, and tentacles.. with 9 ginormous hairy clawed legs.. the creature standing over 500 meters tall..

"Hunger.. THIRST!!! HUNGEEEEERRR!!!!!" Tarrantulus roared.

"Heheheheheh.. HAHAHAHAHAHAH!!!!!!!" JillVill was sucked into Tarrantulus's body like black liquid.. until her body appeared, her uppertorso merged to a point right above the disgusting monster's eye. "FEEL THE WRATH OF MY PURGATORY GOD!!!!"

"Feed... on this one!?" said Tarrantulus, her eye rolling around psychotically. "YESSSSSS!!! YESSSSS!!! I UNDERSTAND!!"

From Tarrantulus's  body, a giant shadow engraved with the faces of a hundred disgusting demons blasted out of her body.. and concentrated right into her eye before blasting into Vasto Lorde Misaka.

The blast raged for 500 miles.. like a demonic beam full of disgust and hatred..

"YES!! SEE!!? SEE MASTER DIABLO!?" Said JillVill. "She is not your bane!! SHE IS A DISGUSTING SHREW!!!"

"M-Master!!" Tarrantulus exclaimed. "L-Look!!! This can't be!!"

The dark demon beam was suddenly being overpowered by a giant black sphere of black energy... A giant cero was overpowering the blast..

Vasto Lorde Misaka screamed into the sky.. and her chest began to morph and change.. until a scarred and grizzly looking hollow mask began to appear on her chest..

"NO!!" said JillVill. "It can't be.. THE BIRTH OF A PURGATORY GOD!!!?"

"Incredible!!!" said Oculus. "The remnants of her Numensapien Soul are merging with the hollow, dragon, and personal reality!! They're creating a new Hollowfied Purgatory God!!  This has never been seen in the history of the entire Omegaverse!! This is something completely new!!!"

"Keep analyzing for now.." Diablo said. "I want to see where this goes.."

"KILL HER BEFORE SHE SUMMONS IT!!!" JillVill screamed at Tarrantulus.

Tarrantulus put down one ginormous leg and slammed the foot down on top of Vasto Lorde Misaka like a monster stepping on an ant.. but Vasto Lorde Misaka stopped the giant clawed foot with one hand...  with the other hand.. she wrenched the mask out of her chest.. and threw it into the air..

"Skotadi..."

The mask grew massive as black muscles and skin grew from the mask.. turning into a ginormous humanoid creature.. it's spine was covered in a giant arch shaped dinosaur like bone armor with massive spines.. a gaping hole was in it's chest.. and white-rib like armor covered it's sides...  The bottom jaw of it's hollow mask was large and brutish with and x shaped red scar marking in the middle.. it's giant arms were brutish and like a gorilla's, larger then it's legs.. and it stood over 100 meters taller then Tarrantulus

Skotadi  growled hungrily as Vasto Lorde Misaka leapt onto his head...

"RRRAAAAAAAAHHHHHHHHHHHH!!!!!" The entire planet trembled once more as Skotadi  bellowed and beat it's chest like an angry ape.

"Incredible.. the first ever Hollow based Purgatory God.." said Oculus.

"Indeed.." said Diablo. "I once observed Fulguras's Purgatory Gods, all of them were beautiful, elegant, and rivaled even her mother's Purgatory Gods in the beauty and elegance... however.. this is a creature based in madness, terror, and instinct.. I never thought Fulguras could be capable of producing such a beast..."

"WELL!!! WHAT ARE YOU WAITING FOR!?" JillVill screamed. "KILL IT TARRANTULUS!!!!"

Tarrantulus barreled forward like a massive multi legged worm juggernaut, plowing it's bulgy slimey body across the terrain, dragging a gouge through the earth.

But Skodati moved at frighteningly fast speeds for it's bulk, it's giant fists moved like gattling guns, each one travelling at several times the speed of sound as they repeatidly pounded Tarrantulus's one eyed face.

Giant shockwaves radiated outwards as Tarrantulus plowed back.

"FEAR'S EYE!!!" Tarrantulus fired another beam of demon face filled energy from it's eye at Skodati.

Skodati roared and grabbed the blast in one hand, crushing it into sparkling dust. "GRAN DIO CERO!!!!"

A ginormous cero of black lighting surrounded by what appeared to be massive blood streams..

The blast struck Tarrantulus and plowed her even further into the ground.. The eye whirled around fearfully. "M-Master!!! I-I don't want to devour this one... it... it scares me!!!"

"GIVE US A BREAK!!!" JillVill snarled. "We ARE fear!!! That is our aspect of magic!! WE ARE FEAR!!!"

"But that Purgatory God.. it's a different kind of fear.." Tarrantulus hissed.

"KILL IT!!! I DON'T CARE WHAT IT IS!!!!" JillVill screamed. "KILLLLL IT!!!!"

And so the two giant gods tackled and grappled with each other, shaking the planet with their deadly clash.

Magma broke from the ground.. mountains erupted.. the giant towering forest was laid into a smoldering ruin...

Skodati was the most vicious of any Purgatory God.. it's power reigned like Hell itself.. it did not speak except when executing a terrifying move of hellish power.

"BLACK FAIRY LAW!!!"  Skodati clasped it's hands together, and a black magic circle appeared with a grissly evil looking version of the Fairy Tail insignia appearing in the middle.

A giant beam of black light sliced off three of Tarrantulus's legs.. leaving burning black evil curse markings on it's body."OWWWWWW IT BURNS MASTER!!!!"

Skodati roared, and two massive ram's horns grew out of the side of it's head in a twisted growth of about 2 seconds.. it then charged and headbutted Tarrantulus, forcing her into the ground.

As this happened, Vasto Lorde Misaka leapt off of Skodati's head and onto that of Tarrantulus. She grabbed JillVill by one of her faces, and wrenched her right out of Tarrantulus's body.

"YOU SQUIRMING RAT!!!!" JillVill beat Vasto Lorde Misaka away and hurled out several dark blood red energy spheres at Mikoto.

Vasto Lorde Misaka easily beat aside the attacks with her tail before she pounced on the Numensapien and began savaging her with vicious electrified attacks.

"YOU MOTHER F*CKING B*TCH!!!" JillVill roared viciously. "HOLLOWS CANT BEAT ME!!!!"

The two charged each other, determined to tear each other apart..

_____________

Natsu awoke to chaos... "The hell?"

The ground was shaking so much.. that he was literally being thrown around like a motionless rag doll.. He stumbled to his feet, trying to keep his footing despite the fact that lava and whatnot was erupting around him.

"Everything.. looks like... OH MY GOD!!! ERZA'S FINALLY GOTTEN ANGRY AT THE UNIVERSE!!! WE'RE ALL DOOMED!!! AHHHHHHHHHHH!!!!!"

"Urrrrghh.." Erza groaned from a distance where she lay.

"Oh.. so not Erza.." Natsu muttered. "OH NO!!! SOMEBODY TOOK AIKO'S BUTTER FINGERS!!!!"

"Owww.." Aiko groaned somewhere nearby.

"Oh.." said Natsu. "Well I'm out of explanations.."

"Natsu Dragneel..."

Natsu stared with silent astonishment.. at Ulquiorra Cifer.. standing right next to him.. as if he had done so all this time.."

"I need you to listen to me carefully.." said Ulquiorra. "We must move quickly.."

"U-Ulquiorra!? What are you!?"

"No time to explain Dragneel.." said Ulquiorra quietly and stoicly as ever. "Just prepare to grab the mask... "

"Grab the what!?" said Natsu, right before Ulquiorra grabbed Natsu's arm and Flash stepped away with him..

__________

Where am I? Mikoto thought from the darkness.. She was naked.. and cold.. huddling her knees in an endless dark void.. no light in sight....

If she concentrated hard, she could see herself.. claws.. blood.. a desire to prey on everything..

"Why?" Mikoto whispered. "Why am I in this darkness again..?"

She wasn't alone... staring down at her from the blackness, were the eyes of Corruption.

"Yes.. I am here for you.." said Corruption. "Don't worry.. I am yours.. and you are mine.. I will protect you from them.. I will protect you from Diablo.. I will protect your friends... I  am your savior"

"No..." Mikoto shook her head. "I'm not yours.. I don't know who you are.. you aren't like my other selves.. you aren't me.. I'm out of here..

"But Mikoto.." said Corruption as she embraced Mikoto with her dark arms.. She wasn't female, or male.. not Corruption.. she was Corruption.. but she would be whatever her subject needed her to be.. "I am yours Mikoto.. come.. I will protect you.. come and sleep.. you need not worry..... not about your friends.. not even your children...

"Not.. worry.." Mikoto muttered as she began to grow drowsy.. "That's.. nice..."

"HEY!! QUEEN!!!" Hollow Misaka's voice came in like an echo. "YO!! As much as I like going beserk out here.. but get it together!!"

"Now.. Mikoto's Instinct.." said Corruption to Hollow Misaka. "You should be glad.. I'm giving you free reign right now.. aren't I?"

"DON'T PATRONIZE ME!!!" Hollow Misaka snarled. "WHAT ARE YOU DOING IN OUR BODY!!!?"

"Oh.. what I do best.. Corrupting.." said Corruption with a small laugh. "Wait.. what's that.. no.. NO NO NO NO!!!!"

Somebody was grabbing Mikoto's hand.. and dragging her straight out of the blackness.. Mikoto looked up with astonishment.. to see Natsu Dragneel, holding her hand.

"Hey!" said Natsu with a grin. "Where do ya think you're going sister!? You've got a guild to lead!"

Mikoto awoke with a gasp, she was unclothed in real life too, however, Natsu's vest was wrapped securely around her, preserving her dignity as she was held in the arms of the bloodied Natsu.. in one of Natsu's hands.. he held a torn Vasto Lorde Mask, which he had ripped off with great difficulty.. and he was standing on the disintegrating smoldering ruins of Skodati, who was now disintegrating with nothing to sustain it's presence (Purgatory Gods never die, they merely return to the source of it's power... aka the Numensapien who summoned them.)

Tarrantulus and the other Numensapiens were nowhere to be found.. Ulquiorra was standing nearby, his sword drawn..

Natsu panted and grinned despite the blood dripping out of his mouth and body. "You.. nearly killed me for a moment there... but it's nice to have you back..."

Mikoto burst into tears... "N-Natsu... You idiot...if you died..."

"If I died.." said Natsu. "Don't be ridiculous.. haha.. we both know I ain't going to let that happen..."
