More of a Mutualyst

Already huge and superhuman shark gets a gooey space alien legally not owned by Marvel. She's down with it, the alien is down with it, buildings... maybe less so

Jack didn't need much when working on cars, and she refused to need much when working on spaceships. Okay there were some unavoidable differences. A lot of them really. And she -did- spend a couple years actually learning rocket science for the big space race. But the point was, as long as there was an atmosphere, she was going to be working in the same pants with the same hand tools she always was. Just with a few more advanced magnetic manipulators on the side and a tram full of fuel behind her.

It was what led to her getting a face full of bright red goop, finding the needle-thin hole in the shuttle's shielding and the millimeter-thick bulge behind it that was responsible for the 'dangerous impurity' that had gotten into its workings. Jack had opened it up and immediately got squirted for her troubles. 

Of course, there was a -reason- she didn't care much for protective gear, so she just sucked it up and didn't think about it again until she was finished with repairs, waving bye to her boss after the favor and giving her the explanation of how it went.

 Another job well done, and she'd be free to do just about whatever she'd had planned for the rest of her day, and given the goo that still clung to her face, perhaps a shower would be the very first on that list of tasks to do. Whatever that stuff was, it was sticky, enough so to outright cling to her skin, and yet, she could hardly feel it, almost as if it wasn't there. A second skin, yet it stuck to any other part of her that came into the slightest contact. Perhaps a decontamination would be a more proper avenue given the strange substance. That "goo" shifted along her forehead, undulating, working its way into her every pore, binding to her body at the cellular level. 

That small fragment of a much larger being barely clung to life, its base instincts driven to find a host, anyone, anything, just to sustain itself long enough to fully grow into a sentient being once again. That process would take long, weeks at the very least. Spreading, growing, draining a host of energy, yet bolstering the body in return. At least, that should have been the case, if it's host was anything close to normal. In an instant, that small fragment of alien substance erupted outwards, a fan of thick fluid akin to an eruption only to culminate inwards, enveloping its would-be host. 

"YEEEESSS....so much energy! So much potential!" 

"Oh, hey." Externally, Jack stiffened, but internally she visualized herself giving a polite nod of the head, turning her attention to the voice inside her. It explained a lot, actually, she had some kind of space parasite thing going on. She'd read comics. And met aliens for that matter. Unless it was a full on The Thing situation then this was no reason to be impolite.

"Welcome to Earth, and also me," she directed at the creature, watching it spread over her skin and wondering if this meant she needed to -not- take a shower. The really heavy duty decontamination sprayer could probably get it off but it'd also be like turning the pressure washer on your neighbor as soon as they stepped on your lawn.

The thing skidded to a halt at the casual greetings. However it was set on its goals, spreading, growing, and sustaining its host. That crimson goo shifted along her flesh,integrating into every pore, every fiber of muscle, lining tissues with adaptive substance already forcing its new host to shift and grow and amplify her natural traits at unnatural rates. Usually the entity’s kind would have to garner a feel for their hosts' limits. Just how much could one span, how much could one enhance without ending the lives of both. Despite how much that goo fed from her own form, that small spec having already begun to span her entire torso, there seemed to hardly be a dent in her own make-up. It was as if her form was condensed, the slightest inch of space along her form garnering the most dense substance it had ever known. Just what was she?

"Greetings...?"

It responded, unmistakingly confused. Either way, this was soon to be its mind, as well as body, even if she was calm, and conscious,  as well as her own mind remaining particularly sharp even as it spread through her, sinking into her mouth, crawling down her throat, spanning wider and deeper, pulling and tugging at her muscles, as it quite literally worked and simulate those muscles from the inside out, pushing them thicker beneath her skin in real time. The more it integrated into the more it realized, she was calm, immensely so. 

"Do you understand the situation you're in?"

"Not entirely," Jack admitted, poking a bit at her bicep as claws now impregnated with alien matter pushed into muscle tissue experiencing the same. "I'd have to run a lot of tests to confirm precisely how my biology is being altered, but I do get the gist. You're a tissue-conversion consciousness, like a grey goo, Lyralian slime mold, or Craxian retrovirus, right? You find a host and then use their biological base to create a body for the both of you."

And that body was usually stronger, faster, etc. than the original to outcompete in its niche and force saturation of the conversion consciousness in the environment. It wasn't an especially common adaptation, but it was still fairly basic biology. Though the ones that were mutualistic tended to be... less spooky... than the parasitic ones.

Also she couldn't really breathe without making a deliberate effort and sucking her guest into her lungs, but that wouldn't be a problem for a while still so might as well wait it out. "I admit I wouldn't mind. I did always feel kinda selfish being the only consciousness who gets to experience a body like this."

The being didn't exactly have many humanoid hosts to compare to, but already it could feel it. This body was extraordinary, it just couldn’t yet see how much. "I see...you're odd. It's one thing to willingly let me in under the pursuit of power." It paused for a moment, the substance shifting all the more. The process should have been instant, but by its own nature, the deeper it rooted itself the larger she grew, the more space it would be forced to spread over her augmented form. 

She was right in the ball park. By the second her biceps swelled, forearms pumped and thickened, pectorals lurched beneath swelling breasts. Bit by bit, alien ooze trailed downwards, working over toned abs and feeding into their definition all the more. Everywhere crimson touched, was met with an audible swell of muscle. Even her internals were fortified from her lungs, to her heart, in turn the symbiote fed and grew right along with her. What was once an angulating mass of goo set to feed and spread, began to gain a sense of self and reasoning far greater than what it should have been comfortable with. A small fraction of her own intellect reflected into the parasitic being. With that understanding came a slew of questions and thoughts most of its kind never cared to ponder. 

"Earth... Are your kind really...that substantial?"

"Most aren't, I'm somewhat of a... special case," Jack said, the usual polite terms she used coming through even with a creature capable of touching her meanings directly. Her actions spoke louder anyway,  a quick pull of her legs put her thigh up and her foot behind her head, letting her compare, the parts of her not yet 'infested' seemed so much smaller... despite still being bodybuilder-bulky by the standards of most of earth. "Though I'm not entirely unique. Or wasn't. I suspect that even those who used to be able to compete are going to have an... interesting time with the new me." She rippled her torso, making sure she still had control over her muscles, and found they responded to her -better- despite their bloated size. Tentatively flexing her arms and watching them pump to the size of her head, then to its height, then even beyond, swelling by the second. 

The moment her arms tensed, the room burst from the sheer displacement of air. Tools scattered, the ship she'd been contracted to work upon toppled and skidded along cracking ground. There weren’t many environments that could handle a flex from her before, that now applied to her own personalized and fortified spaces as well. Still this flex was casual... 

Her new plus one was at a loss. Usually it's kind was primal in nature, and if given an intelligent host, a bit prideful and sadistic, usually spoiled by their captives sheer respect and fear. Having control of one's own body stricken from them often usually proved to be terrifyingly humbling. Meanwhile Jack seemed...eager? No, more so, generous, like they were allowing it to exist out of doing the right thing, like coddling a lesser being. Watching the room tremble around her was enlightening. She could have simply rid herself of him from the beginning, a casual flex and boom, gone. Now however, at the very least it was too late for that, her muscles were their muscles, and with that, it also knew she was holding back, reining in her not so little gun show even as their arms visibly swelled with MORE power. 

On the bright side, that was helping it spread faster. The corrupted flesh started to creep across her lower half. Where her already impressive calves and thighs met with her enhanced neck and shoulders, they too shifted and pumped. The only thing that really could move her muscles at this rate was more of her muscles, or rather, the act of her muscles becoming more. The ground cracked in protest of so much weight being brought to a single point beneath her enlarging leg. Even by Jack's own standards she was becoming huge, not only taller, but wider, yet her body felt lighter than ever, more responsive than ever, even her mind seemed to function so much quicker. 

Slowly her body began to even out, all that raw girth begetting new height. 10 feet of muscle bound genius pushed to 12, then 15 feet, her tail slithering outwards and stretching throughout the room, colliding into tools and work stations made from pure metal left to bend like putty. If her mind was sharper than ever, the same couldn't be said for her passenger. Just as its intelligence and sentience was gifted, something new struck it away. Crimson growth finally reached between her steadily burgeoning thighs. The moment it bound with her cock forcing the flesh to steadily swell thicker and longer, it got its first taste of unrivalled need. Her orbs audibly churned, fattening, filling, production levels shot up multiple dozens of times over just as every other aspect of her being underwent the same. 

It didn't possess her will, her training, her sheer control to concur her urges, yet it FELT everything, it FELT what it was to not only be her, but to be more Jack than ever. 

Being Jack felt gooooood.

Bigger...and bigger...her dick grew, nuts swelling lower to the floor despite her body lurching taller by the second. It struggled to keep up, trying to fully encompass her form until it took hold of those massive nuts. It was the perfect space to grow, to culminate more of itself in a race to keep up, at least until it finished fully assimilating into her body. 

More....MORE....be more.

Jack shuddered as she felt -really- felt her body for the first time in a long while. She may have gotten too used to being superhuman. She appreciated her strength, her size; but she didn't really feel it the way she did now. Growing. Improving. It was a sensation she hadn't felt in too long, knowing she was leaving weakness and normalcy behind; replacing it with a perfection that could only be defined as herself. She had to find something to fuck. Partially to feel good; partially because she deserved it. But mostly because the thing fusing with her body had just discovered her balls; and exactly what it felt like to cram a city's worth of testosterone into one body. Jack was used to it enough to only fuck people unconscious by request. But since the alternative was 'accidentally brainwashing an alien into a sex fiend' she might have to make an exception. Just to test, she found one of the more solid tables in her lab and tried to grind against it. She mostly just ground it. To powder. Which was about what she was expecting from getting a strength boost when she was already world class. It would make getting off... tricky though. She could call her boss. The emergency kaiju destruction unit. Or her personal cumdump whose mods were dedicated to exactly her cock. One of them might survive... In the meantime, her hands just massaged her increasingly gooey foreskin, playing with herself idly 

Everything was so loud, those "casual" strokes were anything but. Every churn of the enhanced orbs were akin to wet cement sloppily crashing about. Every beat of her heart as relaxed as it was, would leave lesser beings to shudder from the sheer force. That didn't speak for her cock, how the stiffening mass of vein riddled girth pumped, not from arousal, but from sheer size. 4 feet of member swelled and thickened along her stroking digits. 4'2 4'3 4'4... growth slow, yet steady, swelling slightly quicker than the entirety of her growing form. 15 feet, and still rising. 

"Moooore~" The entity groaned, any form of coherency tossed to the way side. It knew just enough about Jack, about her body, about her enhancements to hit every spot, to grow and strengthen her form over and over again, yet it would be a slave to its own pleasure, to their pleasure. But slowly the growth began to ebb, the more the gains faltered the more a creeping sensation of hunger brimmed throughout the shark's belly. Even those rumbles alone were enough to shake the room. One couldn’t make all that racket without perking the ears of a particular vixen, one who happened to be eager for any excuse to check in on her keeper anyway.

 "Mistress...?" A familiar voice called, only to correct herself given it was the work place. "Doctor Jack? You good in there?"

 "Oh, hey Vol, I got some bad news," a voice answered in-person as Volaxia quickly found her boss standing over her, the wall between them already gone. That wasn't -that- new, Jack had been in a rush before... her size, though, that was very new. The Jack Volaxia was used to, was... well, not short, she was eight feet tall, but the towering, heavily modified fox was almost twice her size when she got in this morning. At half her size, Jack was still more than capable of manhandling her. With Jack suddenly towering over her... it would probably be worse. That logic might not be entirely sound, but the fox was unfortunately distracted by the 15 foot hyper-ripped shark monster with blood red and black ooze occasionally pulsing under and out of her skin. "I caught an alien parasite that seems to want me bigger," Jack said far too casually. "I already made sure it knows I'm not interested in mind control, buuuut I'm pretty sure it's going to go insane from how pent up I am if I don't get some relief, sooooo..." Jack patted her roaring balls, a shot of pre thicker than yogurt firing out her cockhead and collapsing part of the wall before landing in a solid mass. "I guess if there's something you can do to prepare in the next five seconds, here's your warning!" 

There wasn’t. Just standing before the crimson clad beast was sensory overload. She could hear the churning as clear as day, brewing so much, nuts that had grown worryingly dense. Just as she was about to speak, her eyes caught sight of her abs. Jack was toned, but not like this...never like this. In a mesh of fear and awe, the vixen could see it, the abs shifted...unnaturally so. Every segment lurched, then pumped, flexing in rhythm, thicker, fuller, vaster... The rest of the shark's form followed suit. It was as if those muscles were gorging, feeding in the purest sense, on the very idea of mass itself; with definition gracing her build as casually as lungs filled with breath each moment after. 

The creak of growing bone, the slimy shift of growing goo covered mass, the undulation of writhing bulk that stopped her form from ever standing fully still. Lats flared against her arms, and her biceps fought back by flexing. Her chest grew heavier by the ton, and her pecs grew in behind to make them just as weightless, her thighs pressed together from muscle alone, shifting her stance wider, until they thickened again, more support as her legs extended and her calves swelled to match and her height crept up and up. And all of it just kept growing. All fueled by an inner furnace that made Jack’s stomach roar. …And speak, the beast inside her reaching out audibly “FOOOOOOOD…”

"Hey! No. Not food," Jack scolded the alien creature bellowing from her skin, giving it an instructive swat which... mostly didn't work as she had to flick her own chest for it, but she could lead by actions. "THIS is food," Jack put her hand to the increasingly damaged wall and... forced a geyser of the alien goo out of her palm, consuming everything in its path and leaving her the only mind in the room not incredibly alarmed by the gesture. Her passenger got its first taste of her ability to control it. Fridges, tables, chemical cabinets, documents, she pulled all into her mass and simply... clamped down, mashing it into her body. "Metal, chemicals, dead biomatter, even a few extra mods if you want; we can incorporate as many of those as we want." "THIS," Jack patted Volaxia with her other hand, the fox flinching against the anticipation of parasitic death... which didn't come. "Is a -toy-, we take care of and maintain toys so we can have fun." She was still screwed though. Literally. Jack pulled her in and stripped her, literally consuming her clothes with a twitch of her abs before stretching her wide with growing fingers and putting her cockhead at the gape, pressing inside smoothly, slowly... and overwhelmingly. Jack hilted as gently as she could the first time, leaning in and whispering to Vol like the thing from space couldn't hear. "You might want to fuck like your life depends on it," 

She did, and it didn’t help. Her superhuman height and physique had been born on the back of Jack’s research to begin with. Upgrades to help her recover, upgrades to help her survive, until she could break half the world… or take half the shark. She had wanted to be her assistant, wanted to see the absolute limits of strength.

Even if she broke along with them.

 Her pussy gushed at the prospect of being prey, if only because it was Jack. Spreading her legs, she clenched her jaw, feeling the sheer size of the tip tightly spread her gaping folds. She had never felt throbs so powerful before...or...was it growth? That fresh slew of cables and steel eagerly rushed to surge its host bigger. Grinding, shifting her slick lower lips along that burgeoning shaft, she couldn't take it even if she tried, not because she didn't have the equipment, her doctor made sure her pussy could shatter mountains with a casual grip. But because every second she touched the beast was overwriting her will in another deluge of pleasure.

Jack could feel her assistant -trying-, but the bad news was that with the sharks growing, improving, ascending body even a pussy literally built to milk her couldn't stop from being overwhelmed. Volaxia came. The good news was, Jack got off on being overwhelming, being powerful, and as much as she wanted to be cautious... She wanted to be perfect more. Jack started thrusting, and Volaxia came again with every motion. Jack pinned her down and started smashing the building apart, and the fox shuddered and broke from climaxing so constantly her body couldn't keep up. Jack filled every inch of her hyperelastic insides with growing cock and spewing pre, and the fox lost the ability to feel anything except pleasure, and NEED, and the evergrowing ocean of sludge claiming her womb. 

Jack tried, and her partner broke. The shark girl reached out, using the beast inside of her, willing herself to feel her partner, and she felt everything. Volaxia's every thought, every feeling, sent to Jack's brain and filed with the clarity of knowledge and memory. Crying, bursting, cumming, and bloating... and Volaxia still wanted more. More shark. More pleasure. More JACK. Jack came. And nature took its course. An ocean of tar fired through Volaxia. Not in, -through-. Through and beyond as the boiling, solid mass of sperm and pheromones found there was nothing to resist. Red and black crept out from Jack's cock, and in from Jack's fox, meeting, fusing, and losing the distinction. It didn't end, it couldn't end, and Volaxia's consciousness faded into eternal orgasm, the obliteration of thought becoming the continuation of thought. Her memories, intelligence, and body claimed leaving only ecstasy to call her own. Everything else was Jack's. 

Her final moments were a moan of ecstasy, even as her body broke, even as her moans shifted into a gargled mess. If there was any way to go, this was absolutely it. Despite being weaker, despite being smaller, there was still a lot of her, that vixen offered up her knowledge and memories, but more importantly, she offered up her mass. What followed was a fit of raw pleasure. That alien worked hard to get its host addicted, firing off every pleasure response in her brain, amplifying the sensitivity along that gushing cock, working hard to INCREASE the droves of already immense pleasure. 

It was simple, turn up every chemical responsible with any hint of addiction, what it didn't account for, was that this was also its body too. Jack's mind was definitively the sharper of the two, leaving the symbiote to give in far before her. Sex, food, growth, it was so wonderful, the entity clad to her skin bellowed for more...and more came. 

Another 5 feet of height just like that. Musculature pumped and surged throughout her perfect frame, pushing her even thicker than she already was. Her supple tits fattened, the perfect rear thickened, but most of all, Jack's thighs boomed bigger, rampant growth ebbed with sounding shock waves from those thickening thighs. If the rest of her facility wasn't alert before, they definitely were now. Jack didn't typically fuck THIS hard.

Still...she grew... the already too big cock pulsed and swelled along the floor. 8 feet...9...10... vast even for her own 25ft frame. If Jack was better than ever, her plus one was in a dumb struck stupor. Simply feeling what it was to be her was enough to lose its sense of self. Testicles made of crimson goo erupted outwards, lashing and striking too and fro. No rhyme or reason, riding out that climax that carried on for far too long to be healthy for the creature’s mind. 

Three combined fully in a climax one world could never build alone. And one stood cognizant atop the floods of pleasure, mass, and cum.

It made for another round of 'good news/bad news'. The good news was, Jack's balls were simply too dense to assimilate in their entirety. Even with the mass of several normal people shot straight into her scrotum, she wasn't -entirely- alien down there. This was good news because it meant her cumshot  fired wildly for hundreds if not thousands of feet in all directions, was not made of alien slime and she was not already in the process of absorbing the entire city block. The bad news was... well, cum the approximate heat and density of actual magma spread that far was still enough to destroy most of it. This was bad news because it meant Jack's boss had already shown up with the kaiju takedown squad; only some of whom were already losing it from her pheromones and diving into her nut sludge. ...Though Jack would admit, actually looking down on her boss for once was kinda nice. "Hi Amy! We caught a space passenger from that last flight. I was just... inducting them real quick." Or maybe it was a combination of afterglow and having somebody nearby who could actually take a ten foot cock.

Despite how calm those words were, her body was anything but. Every lash of a tendril cleaved through wreckage, not slicing, or crushing, but absorbing as fast as they could move. Even now she grew, each writhing appendage gorged on rock, and steel, slipping down before each bulge of captured mass settled within her build. RRRR...another fit of growth racked her form, so much weight, so much densely packed muscle multiplied again...and again...quaking the ground for miles on end regardless that she was only 35 feet tall. Despite her work space being ravaged, and the droves of soldiers lost in an instant. It was in that moment that Jack acknowledged Amy, that symbiote attempted to fill her head with its own thoughts. If we could get our hands on her... Of course, those men wouldn't wait. Blunt force wasn't likely to accomplish much, sedatives all the same might not fare well given her body was even further from normal now. 

"I can see that," Amy said, eyeing Jack's lashing tentacles from the side of her eyes. "So, would you say you're not actually on a rampage, then?" 

"Right! Yeah, thanks for understanding," Jack sighed in relief, nodding along as she started to clean up, tentacles growing more ordered as she focused enough to clean up -some- of her mess, reabsorbing part of her swamp and growing to 40 feet. "This is just from me having a quickie. I'm still the same as ever, I just grow now from any mass I interact with." It was so nice to have clarity. Well, nice for Jack, Amy looked stressed for some reason. "That's... not very sustainable, though," the dog girl noted, "Can you... turn it off? Split it up? Er... compress down maybe?"

That was a wonder? Could she? Mostly the second skin was so set on making her grow, helping her to reach out so she could swallow more, the thought of compression was far beyond its currently ravenous mind. Each and every person before Jack's looming form may as well have been food. More sustenance to aid in taking hold of the entire planet. Just as the entity demanded her body to grow, it did, though not in the way it had hoped. For a moment, muscles thickened, fibers showing visibly beneath crimson skin, only for everything to suddenly clench. The sight was almost grotesque. Biceps, shoulders, lats, abs, every inch of her body burgeoned bigger through sheer musculature alone, only for it to suddenly cascade inwards, each action slimming her down just a little, her height reining back slightly yet her strength and weight only built up more, all that consumed mass having to go somewhere, even if her dense muscle appear lesser, it was anything but. Any attempt to dwindle at least seemed to work...sort of... Less height became more muscle, only for less muscle to disperse that mass elsewhere. Flesh  jutted for a moment before a second set of arms burst from Jack's sides, each as massive as the first, only for the same to follow suit with that enormous package between her legs, the one already capable of wiping out city blocks was now met with a second set. A cock just as long and thick as the first, followed by a second surge pushing the size of her orbs to double on the spot, those balls just too potent to seemingly ever be corrupted, yet reaping that growth all the same. Probably didn't help that she was still "digesting" rubble, but that was a start. 20ft of muscle bound 4 armed dual cock shark would have to do for now. 

"Yes, ma'am, I can!" Jack said brightly, taking both her left arms and saluting her boss who was now only -slightly- shorter than her. Short enough to have cocks pressing on either side of her thighs, but tall enough to see the mixture of lust and disapproval in her gaze. "Looks like making more parts is harder than just making them bigger, so if I need to lose a hundred feet later I can probably just bud off a second me," Jack was overjoyed, the problem was basically solved in its entirety now, if she overate she could just duplicate. Of course her passenger did a bit of a double take, wondering if Jack had already stolen its method of reproduction to join her own, and her audience had significantly greater concerns like 'how the hell do we control two of them if we can't control one'; and having twice as many cocks was already its own kind of disaster when Amy was having to hold back some of her soldiers from going straight for them. But at least she wasn't actively trampling them. "That's... great, yeah. Since we're in a lull right now, how about we take you to the deep site and see how you react to different materials," Amy suggested. There had to be one the shark would deal with differently. "Sure thing!" Jack said aloud... though internally she was checking. 'Hey buddy, I haven't -totally- overridden you into more me, right? You're still in there as more than my sex drive? Did you have any goals besides just 'make your host perfect' I should worry about? I don't want to be a bad host." 

"Spread, grow, corrupt. A little piece of me in every living being. Pool their knowledge into my own. Our own. More hands, power in numbers, but...given how adequate you are. It's more logical to use others as sustenance for your own flesh. If what you say is true...and I'm inclined to believe it is. The thought of absorbing others, and shedding excess in the form of duplicate selves. That would be...as you alluded to before. A blessing, a gift? You're so perfect you allow me to bond with you, just so that I may experience all that you are. If there's nothing beyond perfect, why not simply replicate it? Again...and again...? Being you, is far greater than any ambitions my kind usually have." It paused for a moment, thinking beyond that fog of unyielding need to spread and breed. "Whatever it takes to ensure, we never part."

"Awww, I like you too, little buddy," Jack answered with the most wholesome possible interpretation, a little proud of herself for having already convinced a potentially dangerous invader that it didn't need to take over the minds of everyone around her and could be happy with just her. The fact that she did this by being so disastrously strong that a hyper-evolutionary virus couldn't find anything to complain about, she just kind of glossed over. "Well, I'm already pretty immortal, but if your psychic communication works the way I think it does, it'd be super useful for long distance space communication, so I can't see any reason not to bud off an extra me, send them to another planet, get established there, then do the same thing. That way pretty soon we'll know what's up on every world." Jack's intentions were absolutely pure-hearted, violating the speed of light delay to allow communication with different worlds, along with making sure they had a troubleshooter on hand. Though for some reason her cock launched a few ropes of cum so thick it was practically solid, bouncing around the -heavily- reinforced walls of the secret facility as they were almost to the testing chamber. 

"Hey!" Amy criticized her. "None of that until we know it's not infectious."

The symbiote knew better than anyone of her intellect, and yet even it was surprised at how ambitious she was. The idea of being everywhere, holding so much power, HER power everywhere, was tantalising. God if she was aroused at the thought of her own perfection on a universal scale, her companion was outright frothing. The craving for more invoked a new purpose, more not simply in scale, but in number. It needed sustenance, more mass if it were going to truly pull off something of Jack's grand scale. Like clockwork, the belly of the hyper augmented shark suddenly roared with need. The one thing it held to rival her strength of body and mind, was its own unending hunger. A hunger it was more than happy to share. Every touch, every footstep, an opportunity to feed, to absorb, to grow. The soles of Jack's feet slowly feasted upon the metallic floor with every step, passively leaving prints as if it were sand. 

Fortunately they were there. Even more fortunately, it was a smorgasbord. Jack was asked -asked- to consume various dangerous materials to determine how her new biology reacted. Which meant there were absolutely no complaints when she immediately grabbed some nuclear runoff and upended the barrel down her gullet, chugging it down in one clean gulp, using its ultra compact energy to grow taller again... So she could eat the rest of the barrels like a handful of M&Ms, taking the immense influx of energy, enough to run an entire city, and putting it towards the -hard- part. Jack tried to grow a second head. None of it would do much good if she could -only- make the unimportant parts after all. It turned out not even an entire power plant's excess was enough, and Jack had to skip to the next of the snacks while her teeth were still sticking out of her neck, going up to a few small white spheres in magnetic bottles and scooping one up into her new mouth, a face reaching out of her shoulder to take it in... And ALMOST grow 300 feet, before instead focusing all that oncoming mass and energy into making a second head the equal of the first. Of course, suddenly having two hypergenius brains came with an overwhelming element of its own... 

Two minds bound to a single body, if she had displayed worrying levels of control over the symbiote before, it was second nature now. What had once been tendrils lashing about to haphazardly grab and curl along various material, became outstretched webs of crimson erupting outwards at sonic speeds. Each pillar of red web split into more and more simply making contact with each and every object in the room. Solid, fluid, it mattered not. Barrels turn into goo, acids, chemicals, and waste turned to more of her in an instant. All the while the newly formed head fed, maw agape to take in more and more, chomps no longer necessary as the final bites of that barrel simply merge into her being. From her feet a pool of red spread. Bit by bit, it grew, sweeping the floor in crimson, accelerating with everything it claimed. Every aspect of her passenger bent to the will of Jack's minds. The pool of goo slowly spread to every object in the room, machinery meant to test reactions to sonic frequency swept away, tesla coils consumed in alien mass.They weren't receding back into her any longer, rather, they were simply part of her, tech perfectly compatible with bio mass, and the more claimed, the more formed, just as perfect as the original.Slowly it parted, stepping out from her other self bit...by bit.

Having a second brain was exactly what Jack needed to perfectly absorb the instincts and muscle memory of her passenger. Which was good, because it meant she could shapeshift fairly freely now, but was bad, because it meant she -really- rushed her boss's experiment in a bit of an eating frenzy. She was -supposed- to see what poisons she was vulnerable to, what hyper-dense, space warping objects she couldn't digest, and what kind of waves damaged and disrupted her form. "...None of them, boss!" Jack recovered quickly, acting like she meant to do that as she answered with three mouths. The WHOLE room had had enough in it to do more than clone herself one full time. It had enough for her to make three copies and then some, and Jack eventually disentangled her tentacles from themselves and withdrew them into one of four central nodes. One Jack had jagged, lightning bolt like stripes, having incorporated the generators and now experimenting with her ability to shoot electricity. Another Jack was visibly slightly gloopy, her stripes taking on a drippy pattern as her hair took the form of sludge, occasionally dripping onto the floor and burning through. A third Jack was the one who -hadn't- spoken, now having enormous red wings and carefully rubbing her throat above the gills, a little worried about how her voice was going to sound with the addition of the ability to hypnotize and destroy. And, of course, the original, who had kept the glasses, the extra arms, and the extra cock. All were currently about 20 feet tall, but this was more out of courtesy, as they were now amorphous enough to expand quite a bit further and still shrink back down

 As much as Jack worried for her "little buddy" it could hardly maintain its conscience before given the sheer strength of her mind. Now it served as a network for four of them. What few thoughts did make it through were that of sheer praise. It was proud, proud to aid in making something it once thought perfect into more. To improve a god, is godlike in its own right after all. Now charged by 4 hosts stronger than its wildest dreams, the alien's abilities, much like Jack's own, were so much greater. It felt...good...right... Who knew what else could be possible if those four were allowed to spread throughout more tech,, if a living being came into contact. Still...the more it spread , the stronger all four of them grew, not that they needed power, it was merely a consequence of being them.. "Did I do good? I can make you bigger...more..." The sealed room was practically becoming a cocoon of red, that goo nipping at every corner, looking for the faintest crack to slip forth into more spaces, clinging to wires, crawling along monitors and lights. 

"You did good, sleep, we can take it from here." Jack had inherited the urges, the instincts, and some rather handy knowledge of deep space. She hadn't -erased- her passenger, hadn't fully assimilated him, as ironic as that would be, but what he was now was more of an urge. An instinct to grow. Which she was perfectly happy to do anyway. On her terms. Jack put one palm on the cocoon of red and sucked it all back up, it delivered knowledge, some stolen data, and at least a few computer screens that got dragged along with it, but she wasn't planning to dissolve her way through the whole facility. It was already mostly -her- facility, after all. She nodded to her other selves and Siren Jack took off flying, rising up through the roof of the underground bunker like it wasn't even there, her body simply absorbing everything in her way as she passed to the surface. The original picked up her old boss in one hand, holding her up to her face with a smile. And said, "I have a few proposals for the budget, going forward."
