Chaos Theory
"What's happening?"
"I'm not sure. How are you feeling?"
Weiss sits up, her mind reeling from the flowing energy, both hers and foreign, as she senses a strange shift in her abilities. Looking at her hand, she flexes it open and closed with the mixes of aura flowing through it, for almost a second feeling something in her perception shift as she gazes at the energy…
Its nature isn't natural, almost a shift in reality itself as it almost looks like with the aid of Jaune's aura she can gaze around, or through, her limb… somehow.
But what's undeniable is the immense energy welling up inside her, sharpening her senses well beyond the norm and impelling her to grasp every minute detail of the situation around her.
"I am making humanity pay for what they've done!"
Did no one else hear that? Quickly looking around and almost forgetting the apprehensive Arc, Weiss doesn't see where the voice comes from within the grand hall but simultaneously senses the airships and White Fang outside… despite the wall between them.
Weiss quickly shakes her head and lets whatever energy is amplifying her aura do its job before glancing back up at her unexpected savior with a smirk, "Better. Much better. Keep it up."
A small chuckle from the knight, "You got it."
As Jaune closes his eyes to finish his work, Weiss takes advantage of the slight pause in the room due to the arrival of what she's now sure are the airships to make sure she was seeing correctly… and sure enough, her sight and hearing are augmented to the point of not only hearing around the grand hall, but somehow "seeing" as well, as if her perception was overcoming the fabric of space at that moment.
In fact, as she "looked" more closely to see a familiar figure with a familiar red katana rush a MUCH more familiar figure without success, she could almost swear that was-
"KILL THEM!"
Weiss snaps her head back up at Jaune, calling him out of his aural concentration.
"Jaune, we need to move, there's no more time!"
With a silent nod, the Arc helps her to her feet until she's sure she can stand, and managing to scamper over on her own to the fore of the central platform before their opponents have fully recovered, Weiss focuses her sight on the burly fighter who'd managed so much damage against them.
"He's going down first."
"Uh… Weiss…?" Jaune begins, his words lost on the scowling heiress as she gets down to one knee and creates a summoning glyph… except this one is unlike the others.
He'd seen her prior glyphs, clean, clear, pristine white… but this one is larger, somehow darker, its very existence and presence causing every one present in the hall to look over, locked in place by inexplicable fear by the aural construct that seems so intense, it almost looks like it's shimmering – or shivering – with multiple mirror images of it shifting slightly up and down around the heiress with an audible hum.
The image in her mind was clear at first as well… simply the summoning of an aural copy of a Queen Lancer grimm… but somehow the idea itself warps like the original perception of her hand, the image of a Grimm being lost in her mind and the concept of the Lancer remaining and shifting into something else entirely…
"Guh… nn… nnnyyaaaargh!"
Outside the grand hall, Hazel grimaces, observing the shifting tide of the situation as a Monkey faunus wielding gun-chucks engages a number of the White Fang while the rest try to fire at the newly arrived Mistralian airships. Hazel is about to step forward and enter the fray then a thundering boom from behind him catches his attention…
…followed by the sickening squelch of metal piercing his side.
With the tip of a spear-like weapon protruding from him, Hazel braces himself with the expectation of being pulled backwards when the resistance suddenly snaps, triggering a second explosion from the tip of the spear that blows him back several meters. Groaning from the disorientation, Hazel finds himself looking up from the ground several yards away between the fighting outside and the grand hall with some surprise that the weapon hadn't blown a chunk off his flesh. Thanking the fire and shock dust within his system for providing resistance to the heat and impact respectively, he stands slowly but finds himself in consternation when he pulls his hand back to find a crimson red insignia on the back of his palm.
"What in the…"
"What in the…"
Jaune can say no more, gawking at the young woman in front of him as she drops her arm… an arm with a barrel that just fired arguably the loudest spear he'd ever heard. Her attire – including the white and blue winged insignia on her back – is unlike any hunter he's ever seen, the two similar barrels housing some sort of hook each strapped to her hip unlike any weapon he's ever heard of.
She turns back from within the nearly crackling glyph as it begins to rotate uncontrollably, heedless of the equally dumbfounded glares directed at her from within the room as she simply glances between the hand of the knight and the kneeling heiress before her as she remains somehow locked in the summoning trance of the unnatural glyph before directing her attention to the knight.
"My name is Mikasa Ackermann. Which one of you is my Master?"
"…WHAT."
And at that moment, Weiss cries out as the furiously rotating glyph underneath her and the mystery woman shatters into pieces, bolts of light shooting around the room, through her friends, through the walls, through the floor, and with wide eyes clasps a hand to her racing heart as she gasps out to the young woman, "You…!"
The young woman merely regards the heiress for a moment before reaching a sort of understanding and kneeling down to Weiss' level and placing a hand on her shoulder, "Master… Schnee. I've temporarily neutralized the biggest threat to your well-being. Unfortunately, it seems your summoning circle was supercharged and splintered into others with enough energy to bind themselves to nearby candidates with enough power to be suitable Masters."
"Not a single word you just said made any sense," a bewildered Jaune drawls quietly, but almost as if being ignored completely is only met with a glance by Mikasa in his direction which he slowly realizes is actually directed to someone standing beside him.
"…like that one..."
"Gyah!"
Jaune exclaims, the fright of seeing a similarly aged young man with auburn hair soundlessly appearing at his side causing him to hop back, "W-Wait, who are you!?"
"My name is Emiya, Shirou," the young man replies, glancing around the room with a mildly concerned look on his face, "And… we're not exactly in Japan anymore, are we…."
Mikasa merely turns her gaze back at the heiress in front of her, raising her brows in a silent pointed confirmation of her previous words as she helps her up before turning a second pointed gaze towards the now eerily silent area outside the grand hall.
"Or…"
RAAAAWWWR!
Outside the grand hall, everyone's stunned gaze is locked on the large creature with the build of the boniest Ursa ever recorded as it ominously lumbers over to Hazel's side. Easily standing about a meter above him, Hazel sizes up the creature beside him with the hide – no, carapace – of an ancient Grimm before it turns its blazing red eyes, a strange mix of color that Hazel realizes resembles the mix of gold and red Dust flowing through his own body, towards him.
"YoU… MasTer… ME… DOOMsday."
The corner of Hazel's lip turns up into a dark smirk, his first order leaving his lips as a small section of the crimson insignia on the back of his hand fades into gray.
"Kill everything that moves."
In the grand cavern below the grand hall, ice is heard cracking as Cinder slowly approaches her latest prey.
"So I will take… what is mine…"
Vernal finally stops struggling against the Grimm claws buried deep within her abdomen, but her smirk dies down she realizes something is wrong and turns to face Raven, now freed from her icy prison.
"What is this? Where's the power!?"
"You won't find it, because Vernal isn't the Spring Maiden," the incensed swordswoman replies, taking off her mask and about to open her mouth to continue when-
"RAVEN IS, YA DIPSHITE!"
The two women's eyes trailing flame-like energy, they both stand armed and Cinder scowls at the strange costumed man who calmly saunters up to them from behind Raven.
"Oh my bad, was that your line?" he continues, his white eyes widening on his mask as he pulls out one of the two katanas slung across his back and uses it as a cane to lean on beside the increasingly agitated Raven, "I suck at this multiple protagonist thing, especially crossovers – L, O, L! That's why I just wing it! Oh hey there's a dead girl here, were you two in the middle of something?"
"Who…" Raven begins, her own scowl deepening as the grip around her blade's hilt tightens, "the hell are you supposed to be!?"
"Ouch, a Master can't even recognize her own Servant?" the man continues easily, playfully holding a hand to his chest in mock pain which almost gets Raven's glare to falter a bit as she notes that no one in her clan is idiotic enough to wear that full-body red and black spandex ensemble (not even Qrow at his drunkest), "Look, you really don't even gotta worry about it Angry Bird, I'm only gonna be around for a couple chapters anyway! Honestly, I'm still all atingle that you're actually the Spring Maiden; Rooster Teeth really played that one close to the chest, I mean, the show was losing momentum at this point but this little tidbit really- whoa!"
Suddenly flicking his free hand up to catch the fearsome Grimm claw just inches from his face without flinching with speed that even leaves Raven impressed, a white eye widens slightly in Cinder's direction with a raised brow beneath the mask before the man merely tilts his head around the deadly appendage to glance along the stretched limb to its wielder.
"Ooookay, hot villain with stretchy killer monster arm. I am officially both frightened and slightly aroused."
"Shut up already!" an exasperated Cinder cries out, "Either get to the point or get out of my way!"
"No can do on the second option, Elastagirl!" he calls out before letting go of the claw that whips back to its owner and facing Raven while pulling out a firearm, "Okay, I'll cut to the chase. I got called out from the middle of shooting my third movie to help you break some stuff; last name's Pool, first name Dead. Or as they say in Spanish, La Piscina Muertaaaaaa…."
The pause for dramatic effect quickly withering into an awkward silence due to Raven's fierce deadpan at the costumed newcomer, his eyes only tilt up in an apparently cheery expression.
"Alllright, ya got me! No one calls me that. And in case you or any of these Marvel-challenged readers haven't figured it out yet, ya can call me Deadpool!"
And with that, he promptly raises his pistol – which to Raven's admittedly slight stupefaction actually doesn't come with some sort of blade attached – and fires two flaming arrows out of the air that were hurtling towards them without even taking his gaze off of his Master.
"So as Sir Phanty just said, you're my Master and I'm your Servant," Deadpool reiterates again (annoyingly), "So tell ya what. Let's you and me take care of the One-eyed Wonder with the gangly arm and we can go back to your place and make kinky bondage love with you wearing nothing but that mask and those boots, dealio?"
Raven's glare cracks with a slight twitch, her teeth grinding as she merely turns to face Cinder with a grunt and a murky stew of mixed emotions underneath… she would've outright denied the latter part, but in the mix of having an unexpected ally against the veritable threat of the Grimm-like Fall Maiden, punching him in the face, stabbing him in the face, shooting him in the face- "Dude. Really?"
Shut up.
…and a host of other deeper, more southern emotions -"cough, in the nether regions"- can't quite bring herself to say anything at the moment.
On the other hand, Cinder's glare at the newcomer is outright murderous, the idea of some crackpot lunatic delaying her acquisition of the power that was rightly hers leaving her with the singular most potent intent to zap him in the face when-
KRkRrRZzZTZZztTTZAAAP!
"Yipes!"
Massive twin bolts of electricity suddenly converging on Deadpool, Raven twitches her head around to see he's been blasted clear across the platform back to the elevator before both she and the astonished enchantress turn to the black-hooded second newcomer who appears at her side.
"Powerful Is The Killing Intent Within You… Goooooooood~" the figure begins slowly with a deep voice seemingly warped by some sempiternal energy, every word pronounced with chilling correctness which seems to complement Cinder's equally eloquent charmingly-spoken style perfectly, "Let Us Demonstrate To These Feeble Opponents Their Utter Lack Of Hope Against The Power Of The Dark Side!"
"Oof… that's gonna leave a special kind of hangover in the morning," a charred and smoky Deadpool slurs as he slowly stumbles back to Raven's side before vigorously shaking his head out of his stupor with a sound not unlike a dog shaking off water, "Y'know, I'm kinda not sure why you two even need us in the first place – ya both already have the power level of Servants anywa- holy giblets, that's a Sith Lord. Sidious?"
Awkwardly going stiff at the sight of the hooded figure as its scarred lips contort into an evil grin behind its hood, Deadpool merely looks up towards the top of the cave and shouts to no one in particular.
"HOW MANY CROSSOVERS ARE YOU GOING TO MAKE?!"
I'm back, baby. So I'll make as many as I damn well please.
To BE CONTINUED…
A/N: So. Looking like a three-shot based solely on that Vault of Spring Maiden episode arc.
And yes, hi. There's a lot to explain but I'm barely getting back into the swing of things and can't manage spending hours on explaining several mini-stories of what happened the past 2 years to a few dozen people, at least not quite yet. So I've posted a neat little abridged version on another fic in my profile.
Speaking of which, this fic is more like the spiritual brother of Fulcrum (yes, that Fulcrum, hint hint), so while that fic will eventually be continued, maybe, this one is more like a warm up to getting back into my mains in the meantime.
So to answer two likely very popular questions upon your reaching this point:
Will I be regularly posting after this? Not really, can't make any promises while I'm recovering my writing muses back to health. But the messages I've left elsewhere do point to certain incoming things.
Will this fic be labeled a x-over? Sure, if anyone can possibly explain how to take several fandoms and categorize a fic accordingly on this site; if not, then limiting the scope of this crack-shotty work to just two fandoms is just. Not. Right. And just cuz there isn't an option to toss in multiple fandoms into one story doesn't mean I can't. It's 2018, people.
Gotta let a recovering writer have some fun, eh? :D
I'll do my best to get back to PMs and reviews, but I'm still stuck in the history dating back to 2016 so bear with me… this could take a while. In the meantime, peace out…
And Happy Reading!
