If there was one thing the two companions that were heading into the dimly lit hellscape around them, it's that they didn't know what the heck kind of force in all the infinite dimensions forced them into this scenario.

One of them was Pinkie Pie, the ever energetic busty party pony. She may have been slightly aware there were cosmic forces constantly at work, but even a pony of her expertise could still get confused at the swirling void she and her new companion were trapped in.

Her taller companion was a very special type of humanoid. Her name was Rias Gremory, the kind-hearted crimson-haired Ruin Princess. Just don't tell that last bit of her title to her face. She may have been a demon, but sights like this were still discomforting, especially when she just got out of the shower and she was clad in nothing but a towel.

"Soooooo....we're doing a crossover, I guess?" Pinkie asked her.

"Not sure what you mean, but I guess so. Still, this is humiliating!" Rias clung her towel as she tried to hide her private areas, if one knows what I mean. "Whoever sent me here must have an explanation under 30 words or less or I might run out of mercy today! At the very least, you came here with clothes."

Pinkie thought for a moment. "You know, you can take the towel off. It's just us girls. In a dark and spooky dimension, but hey! No worries!" She smiled.

Rias sighed. "Fair enough. Not that I had much shame to begin with." She just let the towel fall, exposing her tall slender frame and massive rack. It was enough to give Pinkie pause. "What? Just us girls." The demon lightly teased.

RIP! Pinkie just decided to tear off her clothes in one fell swoop, revealing her chubby, but still youthful body. "Yep! You've got that right! Although, this does increase the chances of us getting ravished by whatever lives here. Mmmmm...hope it's got tentacles." She grasped her face as she fantasized at the thought.

"As a wise man once said, business before pleasure. We need to at least find an exit." Rias crossed her arms as she examined the area. "Do you see anything?"

"I spy with my little eye...something dark!" Pinkie pointed to a random area of the void.

Rias sighed. Apparently, this girl was more interested in having fun rather than finding a way out. She didn't mind such a thing, but slightly desperate times call for desperate measures. Suddenly, her ears picked up something. "Do you hear that?"

"Hear what?" Pinkie put a random corn-cob to her ear. "Hmmmm...there it is!" She dropped it as she peered into the dark.

" W̷e͘ll̀,̛ ͡wel͠l.̢.̕.͏I w͟a̢s ho͢pi̶n̸g̛ T͏wi͜li͜g͘h̡t an͞d ̀C͝èlest͘ia ͞w̴oul̶d ́c͢ome, bu̸t̢ I'̀l̸ĺ tak͝e͘ wh̡a̷t̀ I͞ ̷c̕a͞n g̨et̸. " A guttural female voice slurred.

That alone was enough for our heroes to prepare for the worst. Pinkie got out a random rubber chicken, while Rias prepared an orb of demonic energy in her palm. Her black wings extended as well just in case.

"Is this the monster that lived under my bed when I was 8? I thought we had an agreement!" Pinkie exclaimed.

" Yo͠u̢ did. ̀I͝'̡m͝ ̵noţ ̛hi̢m.̧ ͜I'̧m̡ ̵w͏ǫrs̶e̵..̶.a̡n̶d ̕v̨e̢ry͟ f͝ami̴ļiar." The voice continued.

"Show yourself and, perhaps, we can work something out. Remember. The more you keep me away from Issei, the less likely your chances of survival are!" Rias threatened.

" Th̛a̢t͟ ͟fo͜o͟l̕?͢ D͠on͘'̕t͝ wast͜e ̸your ͡br̶ea̢t͝h.͝ ̛H͟e͏'s not͢ ́c̕o̴m̛inǵ t͠o͝ ̀s̡w̸òo͡p̶ ̴i̴n̶ ̶ańd̸ sa̛ve̷ ͏thé ͏day.̶ Nei̧t̵her̕ are̸ t͡he͟ E̕l͏e҉m͞ent͟s o͏f͠ H́a͞r͜mon̶y. ̢Yo͡u'r͟e bot̡h͜ ͝ḿin͝e͘, ̢ǹow͜." The voice let out a horrible cackle.

Suddenly, a large dark mass erupted from the ground in front of them. It was a titanic blob-like monster that had a ghost-like face smeared all over its blue-berry black front. Two massive arms waved in the air menacingly. A low bellow came out of its mouth.

" B̧eh̀ol͡d!͘ Ḿy̵ ult̡imate cr̕e̢at͞io͡n!̵ N̢i͜g͡ht͠mare Flan͠!͞ " The voice cackled.

"Eh. I'm more of a pudding fan myself." Pinkie shrugged. "Wait a minute?! Is that you, Nightmare Moon?"

" Tis I̡! I ̛g̵ot̕ ̵bet͠tęr̵, ͞a͡s ̶i̶t̴ s͘eem͜s.̀ Th͢a̕ţ ma̸t̡te͝rs̛ ͝li̢ttle no̷w.̷ You̶'re҉ all͢ ̴a̸b̢out͟ to ͘be͜c͡om͠e̷ s͠ooo͟oo͠ mu̶c̀h̕ b̧e͢t͝t̴er ͜than you̷r m͡ortal͞ ̸f̵orms c͘a͟n ͟bèa̸r͜!̢ " Nightmare spoke as the Flan lurched its way towards the duo.

Rias wasted no time pelting the flan with her Power of Destruction. Namely, a barrage of red demonic energy bullets as she flew about. Pinkie stuck with pulling her party cannon out of her hair and firing away.

"That's odd." Rias remarked out-loud. "Normally, such a plan looking enemy would disintegrate instantly. What sorcery is this?!"

"I͏t'͞s s̀impl͝e.͟ ̷I̛t m̧eans̛ ͠y͡óur l͝ife̶ is ͠co͘mi̴ng to ̨a̡n̕ ̛end!" Nightmare replied as a sudden tentacle punched through Rias' wings, earning a screech of pain from her.

Before Pinkie could react to that, another tentacle smashed through her cannon, reducing it to splinters. Rias fell to the ground as a surge of tentacles headed straight for the two.

Pinkie felt one latch to her face, muffling her sounds. She tried to pull it off, but all that did was attach her hands to the sticky mass. No matter how hard her Earth Pony legs moved, she felt herself being dragged into the pulsating mass. Her face was starting to burn as the tentacle was starting to absorb it. It was only a matter of time before she slipped and catapulted into the flan with a splat.

No matter how hard she pulled away, she continued to be absorbed. She screamed so loud that the sound threatened to break a hole through the muck-like substance, but it grew fainter as time went on. Her head and all its puffy hair was the first to go. Eventually, she stopped moving entirely. Lifelessly, the rest of her body was absorbed into a fine pink liquid inside the mass. It seemed to be storing it for later.

"M̧mm͞m͜mm̀...I think I ac͠q͠u̷įŕe̛d́ ̵a ͞t͠a̛stȩ for̷ pie͟ abo͟u̡ţ n͏o̸w. Now,͠ ͢as f͟or ҉y̵o̢u, d͝em͢on.́..I̢ ͠thiǹk͜ I'͜ll̴ ͢t́a͝ke ̨m͏y͞ ̧time.̡ ̶You̕ have͝ s̵u͟ch ̕a ̀h͝a͟un̶t̴ingly͡ ̴bea͢utiful ́b͠o̡dy,̶ ̢af̸te̢r a͏ĺl." The flan grew a tongue just so it could lick its lips with it. Eventually, it towered over the fallen demon, who kept firing orbs at it fruitlessly.

"You will never take me! You hear me?! Ne-AHHHH!" Rias screamed as a huge droplet of the goo landed on her hand before she could fire another orb. Her hand vanished inside the muck as it trickled down her arm. "NO! I won't let this happen! I don't-MMMMMPH!" A much smaller droplet hit her mouth, sealing it shut.

"H͡u̵sh,̷ ͝my͡ litt̷l͝e ҉de͡mon̡.̶.̧.͟yo̵u'l̢l̡ ̀fe͝ȩl͜ ̡so m͏uc͝h̵ bètt̷e̸r ҉when͟ I̛'m̡ done̛ ̢wi͡th y̴o͟u̵. ̧I̷t͝'̷l͞l̡ on͏ly̸ ͢c̴o̷st͞ you͘ ̡yo̴ur ̵s͏o̕ul, ̧i͞f ͢yo̴u͞ e͜v̡en̢ ͟h́av̛e ̵o̡n͞e." Nightmare cooed as the flan lazily moved forward, enveloping Rias' feet.

Already, the end was coming fast. Her legs were being reduced to red liquid inside the beast and her arm had turned into a puddle that moved towards the advancing mass. Tears began to drop from her eyes from the pain and the sheer hopelessness of the situation.

'Issei! Where are you?!' She thought in a panic as her pussy was reached. 'It's...it's going inside of me! I can feel my insides being rearranged! I...I don't know how much long...how mu....nuuuuoooohhh...' Her mind began to shut down as soon as her large breasts were enveloped. She no longer struggled. 'Iss...sei...' Her thoughts were reduced to nothing more than oblivion after that.

With that, her head followed suit. She was now lost to the flan, but the nightmare was only starting. The two liquids, one pink and the other red, began to merge. Eventually, the congealed substance created was spat out.

"Ima̴g͢in̶e ̡i͝f yo͏u w̸il͝l.̕ ̛A ̛whole͏ rac̵e̷ ̛of̷ cor͝r̴upted ̷fusions be͢t͜w͟e͞eǹ warri͟oŗs̵ ̀fr̢om͜ ac͝r̛òss ̕t̢he͢ mu͟l͘ti̶ve̷rs͞e̢.͘ ̀I sh͜alļ ́sp̧r͞ea͟d ̴e̛tęrnal̴ ̵n͢ig̕h̕t͜ ͏wi͜t̀ho͟ut̶ muc̴h̕ ҉tro̡ub͠le!͝ ͢Wh̶at ͘a̶ g̨l͠ori͡ous̕ ̨th̸oug̕h͝t͟!" Nightmare giggled to herself as the pink-red substance began to form a body.

The skin was rubbery-hot pink. The legs forming were long and ended in hooves. The body was starting to greatly resemble that of Rias, but with a slightly chubby belly. Her tail ended in sharp edges rather than curls. The pussy dripped with demonic fluids that turned the ground purple when they touched it. The arms that formed wasted no time in fondling the J-Cup breasts that were forming. Finally, with a moan of pleasure, the head formed. It was of Pinkie's, but with red eyes and redder/sharper hair.

"Muh...wuhh....guhaaaaa...." The rubbery creation spoke mindlessly in a fusion of her two creator's voices as her long tongue fell out of her mouth. "...Mis...stress?"

"P͘e͠r̕f͡ect̴.͏ ̀You̧ kn͞ơw̶ your̴ p͡lace̡. No̶w,̧ w͜ho ̕a̴r̀e you?̶ " Nightmare ordered.

"We...are Rias...Pie." The fusion moaned as she placed two fingers in her large pussy.

"And ̛w͏hat̴ i̸s͝ yo̢ur mis͜si͏on?͞ " The evil one continued.

"To corrupt...to spread...to make more of me..." Rias Pie licked her lips. "I want to fuck...Dashie...I want to fuck...Xenovia...I want to fuck...everyone..."

"Th͢a̷t's ͏the ̷spi̷r̀it̶. N̕o͏w͠,͘ ̀g̸o͞ ̀for͡th́.̴ ̢I e͢xp̸ect gre̴at ͟thin͜gs ̕f̶rom ̨y̵ou." Nightmare's voice faded before opening a doorway to Ponyville. Eventually, one to Rias' world would open, but one thing at a time as they always said.

Rias Pie hummed happily. Pretty soon, the objects of their affection would fall to their new mistress. She wondered as best as she could with her broken mind if Dash's wings would look great on Issei.

And perhaps-HURK!

"Aaaaaand, slash, goes the katana." Deadpool said as the author slumped over, paralyzed with pain. "I mean, really? That's it? They get eaten by a random blob monster a has-been villain summoned? What is this? Fanfiction.net?"

-_-: There's also a feeling of disgust that won't stop washing over us.

^-^: Yeah, we're into that stuffed unicorn we're keeping so tucked away at home, tee-hee!

"Absolutely disgusting!" Rias admitted. "Say what you will about what goes on regularly in my universe, but I've gotten stronger since my day I first met Issei! Such a beast wouldn't stand a chance."

"Did you really have to stab the author? Maybe he just needed a hug?" Pinkie asked the merc.

"Eeeeeeehhh...he'll be fine." Deadpool shrugged. "Now, get a load of this. SUDDENLY, XENOMORPHS!"

A horde of the horrid alien monstrosities burst in, screeching and hissing in anticipation to kill. Drool dripped down to the floor from the first Xenomorph that dared to pounce on the foursome, only to be sliced vertically by Deadpool.

"Might I ask where they came from?" Rias asked as she blasted a good chunk away with her Power of Destruction orbs.

"They're probably pissed about the reception Alien: Covenant got. Plus, we're hopping on the bandwagon here! Ol' Batman, Superman, Green Garba-I mean Lantern, and even that sexy piece of ass, Witchblade, deal with this guys every time a writer runs out of ideas!" Deadpool reasoned as he shot on Xenomorph in the tongue.

"I'm gonna welcome ALL OF YOU!" Pinkie shouted as she shot wave after wave with her party cannon.

"Let's get this party started! Yee-haw!" Deadpool spun in the air like a ballerina, firing his guns all about.

Rias face-palmed. The sooner she got back to her world, the better.

Author's Note

Special thanks to rmcboy47 for the suggestion! Sorry that the Xenomorphs weren't directly involved in the vore, but I was halfway into writing the chapter when you added that. For future reference for the people out there, be sure to be very specific before you post your idea and/or send me mail about it.

So, yeah. A Final Fantasy enemy, a popular character, a demoness, a merc with a mouth, and a sliced spine for me. Yep. Be sure to keep sending those suggestions, folks!
