This was an odd one, horn growth is not one of my comfort zones and I wasn't entirely satisfied with how it came out. Still, I'll let you all decide.

Respect

Rose grinned as she made her way downtown. It was nice to see the streets bustling for once - the town was typically quiet and reserved, but with the annual pokemon 1v1 championship being hosted here it was currently a hive of activity. Participants and spectators shared drinks and chatted about upcoming matches, most of them entering in the amateur or middleweight leagues. Rose wasn't interested in either, for she was here for one reason and one reason only. Last year she'd been knocked out by a lucky shot, a critical stone edge proving too much even for her toughened body. This time though she was back, bigger than before and tipped as a favourite to go all the way in the pro division.

For Rose, being bigger than last year was quite an achievement. As a fighter known for being notoriously large and powerful, she had taken her already impressive physique to insane proportions, months and months of training honing her flesh into weaponry. The houndoom stood an imposing 7ft tall and weighed nearly 300lb, all of it rippling muscle. She was shredded to the extreme, not an ounce of fat on her body - no stone edge was going to take her out this time.

She was getting plenty of looks as she walked, but it was hard to tell if they were because of her body or her reputation. Last year she had been a crowd favourite thanks to her fiery fighting style, and everyone was excited to see her return for another shot at the coveted trophy. With the tournament starting in a few hours she'd wanted to get a quick workout session in beforehand, just to make sure she was ready. Admittedly walking there in her fight gear (customary tight-fitting sports bra and pants) might not have been the best idea, but hey it gave the crowd a show. She saw more than a few excited kids pointing her out and jumping up and down, squealing loudly, and any other time she would have stopped for autographs. Now though she was focused, in it to win it.

The gym in question was one where most of the higher level competitors hung out, being the only one in the town equipped with heavy enough weights. Walking in she was greeted with the sight of muscular pokemon pumping iron, sprinting on machines, practicing moves over and over. A viewing gallery was set aside by the entrance, and Rose noticed her entry caused something of a commotion. One little vulpix in particular shouted something out before clenching a paw and raising it in the air, beating on her chest with the other paw. Rose smiled as she recognised the gesture, and for just a moment she decided to indulge the fan. She ignited a fireball in her hand, mirroring the vulpix's movements and crushing the fire in her clenched fist.

"Bring the HEAT!" She shouted her famous catchphrase, laughing at the cheers coming from the viewing gallery and at the nervous looks from the other lifters in there, intimidated by the world finalist of last year. The phrase had started as a battle cry, something she did to psyche herself up before a fight, but by the end it had become something of a trademark that people recognised her by. Clearly it was still very much remembered.

As much as she wanted to go over and greet them, she knew she'd be signing autographs all day if she did, and besides she was here for a reason. She rooted around in her bag as she went over to the free weights, searching for her water bottle. After a few seconds of rummaging though it became clear that it wasn't in there.

"Shoot." She swore under her breath, realising exactly where it was. She'd left the stadium in such a hurry she hadn't even gone to her locker, and she just knew the damn thing was in there. Still, there was a new vending machine in the corner, so she fished out her wallet and went over.

As always the world tournaments were a big draw for local companies, many looking to promote their brands to one of the biggest audiences anywhere, and new machines like this one were a common sight. Rose didn't recognise the brand, but it was brightly coloured and full of promises, and she didn't have time to be picky right now. After dropping a couple of coins in she retrieved her drink and went to get on with her workout.

Watching Rose work out was like watching some massive machine. Her form was utterly perfect, precise to the absolute millimetre, and the weights she used absurdly heavy for the ease with which she was handling them. She wasnt even going full throttle either, holding back so as not to overexert herself - an injury was the last thing she needed. Even at half power she lifted what others would consider far past their personal bests, curling weights that others would consider for their bench presses. It was a humbling sight, but like many professionals Rose was not interested in showing off. If that were the case she would have been doing squats with half a ton of weight on her back. Instead she took it slow and ignored the amazed stares, focusing on working her formidable body.

After a couple of general sets she stopped to take a break, breathing lightly despite the work. As a veteran of the gym she enjoyed the burning sensation of her muscles warming up, blood pumping through her veins as all of that strength was slowly beginning to unlock. She was content to just sit there for a while and revel in the feeling of her body singing with effort. After taking a few breaths she gathered herself and rummaged around in her bag, pulling out the drink and actually looking at it for the first time. It was an electric blue in colour, brightly labelled and almost certainly full of sugar despite what the label claimed. Not exactly what she should be drinking, but she couldn't afford to be choosy. With a shrug she popped the cap and took a deep swig.

As predicted it had a sugary tang to it, but it was much stronger than she had expected. It tasted like liquefied sherbert, insanely tangy and making her involuntarily shiver as it went down. Despite all of that it tasted pretty good, and she took another swig before replacing it, smiling at the sugar hit. Definitely unhealthy she thought, making a mental note not to have anything else sugary today - she took her diet seriously.

As she sat there and let the sensations wash over her, she noticed that for a light workout they felt a little… intense. She knew for a fact she wasn't out of shape, and the gym was well air-conditioned, so why did she feel so hot and uncomfortable? Actually scratch the uncomfortable part - it felt good, like her usual post workout burn but pumped up, and she had a good long stretch as the warmth coursed down her biceps and shoulders. She didn't notice the added length until her fingertips brushed the top of the nearest machine, and she looked at it in surprise. Before she had time to question it another pulse of growth stroked her body larger, and then another had her grunting as her spine jerked taller.

Each jolt of heat signified another part of her growing as she struggled to hold in her moans, her body pumping up to herculean proportions. Pound after pound of muscle forced its way onto her frame in messy spurts, her already defined body piling on mass as her strength soared. Soon those individual jolts had melded together into a long blast of heat, like raindrops in a storm, and she streeeetched her body out to 7'1, 7'4, 7'7. Deafening cracks heralded her spine reforming to allow for more height, her skeleton lengthening as sinews and tendons whiplashed into the new space, all set to the background of that immensely pleasurable heat.

Something was going on around her head. Rose felt like someone was starting to yank on her skull, pulling her downwards with ever increasing force. Her head felt...odd, thick, like her skull was thickening and being slowly squeezed out, and she realised that her horns were growing longer. The yanking was their increased weight pulling on her head, and it was only her bolstered neck muscles that stopped her falling to one side. In fact they were growing so heavy that she could feel her entire body working to stay upright, her core muscles burning as they struggled to support the thick masses of bone up top.

The growth continued, her body surpassing 10 feet tall as the heat remained as organically wonderful as ever. Her backside was beginning to crush the seat she was sitting on due to her weight, so she instead stood up and almost immediately wobbled. She was so top-heavy it almost made her fall over, and she was forced to tense her muscles to stop that happening. Oh but the involuntary flex felt glorious, a great wave of strength rippling through her frame tightening as it went, followed by a surge of heat that again made it easier to stay upright. Now the strange sensation rolling around her skull had changed, she felt like thick dough being rolled out and reshaped. There was much more resistance, like her very bones were ground and reshaped into more pleasing structures.

The next surge of heat bumped her up to 12 feet tall, muscle exploding around her, and this time she was ready for the sudden rebalancing she knew would be necessary as her horns grew even further out. Impossibly they felt even thicker than before, like she had a bad head cold and her skull was filled with cotton wool, only this time it felt more like solid brick. The heat surges were weaker now, not so violent, and she rolled her broad shoulders as she rode out the last remnants of her growth. A light crunch followed by an alien pressure made her wince - she'd underestimated the size of her new horns and how far they extended from her head, meaning she'd just punched them into the ceiling. A light dusting of plaster confirmed this, and she leaned down slightly so as to not damage the gym any further.

"Mirror, I need a mirror. Is there one in here?" Rose's voice was deeper, dripping with irresistible authority, and about half the gym pointed her towards the full length mirror on the far wall. She stomped over to it, not noticing how she casually moved fully loaded machines out of the way with the faintest of effort.

Rose barely even recognised the houndoom staring back at her in the mirror. The beast was 12 feet tall, stacked with what even she would consider an impressive amount of muscle, carrying an air of authority just standing there. But Rose was used to muscle, that was par for the course - what threw her off were the horns.

Ever since she knew her brothers, Rose's horns had been a point of contention. In houndoom culture they were considered a sign of power and respect, and the elders inevitably sported the biggest horns of them all. Rose on the other hand never had - hers had always been smaller, laughably small compared to her peers. It was one of the things that had driven her to train as hard as she could, to build a body that they couldn't laugh at for fear of having their skulls crushed like an egg. But despite the power and the muscularity there was nothing she could do about the horns, they were purely a genetic trait.

Well now that had changed. Her new horns were massive, bony growths that curled gracefully out of her head and gently kissed her shoulders. While the length was certainly impressive it was the girth that astounded her - instead of narrow spikes these were thick slabs of pure alabaster, solid as rock and about as heavy. She could feel the weight of them, the way her head slung itself from side to side, and just from that she knew they were solid bone. Only a few houndoom ever had horns this long, all of them elders, and certainly none of them had the sheer width that she now possessed. She outclassed the elders with these, she outclassed her brothers - these were so sturdy that she could have headbutted a brick wall and come out smiling. It was surreal, seeing a part of her she'd long consigned as a lost cause now be her crowning glory. She didn't thing that anything would possibly be able to outclass a 12 foot, ton and a half body, but there they were.

It was that drink, she knew it was. She turned round to find her bag, wincing as once again she forgot her new height and scraped those impressive horns against the ceiling, adding two more gouges to the roof. The bottle was almost finished but she managed to grab it, holding it up to the light. She grimaced as she saw the ingredient list, which was full of a lot of worryingly long names.

"Anyone here seen this stuff before?" She asked the room, holding up the bottle. A chorus of bo's and shaking heads filled the room, and she sighed as she returned the bottle to her bag. Nothing to do but continue her workout and hope this wasn't permanent.

What Rose hadn't anticipated was the awkwardness that came with such massive horns. Machines that she normally used now squealed as bone grinded against metal, and even with a core like a steel ball of muscle her balance felt slightly precarious, her head shifting from side to side. Weights that were normally challenging proved surprisingly easy, and she was forced to max out the machines just to get a pump going. This meant that when she curled an insane amount above her head, the weight was just enough to tip her to the side, causing her to lose her footing.

CRASH

Rose knew exactly where she'd landed. There was only one place that would result in the sound of breaking glass, and as she felt liquid drip down her face, her suspicions were confirmed.

She'd fallen into the damn vending machine.

The plastic bottles had been no match for her sharpened horns, and now bottle after bottle of blue energy drink was seeping into her skull. She sighed as she extricated herself from the mess, going over to the mirror to inspect the damage and clean herself up with a towel.

She had to admit, with liquid dripping down her titanic body and flowing along the curves of her magnificent horns, she looked good. Like a model, if models could headbutt their way through tanks.

Then she gasped as she saw her horns curl even further out. Evidently the drinks had seeped in and now she was seeing their effects, those chunks of bone slowly pushing their way past her shoulders, the white contrasting against her stretched red sports bra. It was a strange, wonderful pressure thrumming through her head as her bones thickened and hardened, like having a scalp massage while 300 feet underwater, and she didn't know what to make of it. It was just so alien, so instead she focused on the results, which were much more enjoyable. She watched in delight as her already mighty horns sprouted into great structures of legendary size, pure white pillars anchored into her head like trees. They added a very imposing effect to her already towering body, framing her head in a crown of intimidating bone. It was the same sort of fear the devil inspired with his own horns, but there were not just regular old puny goat horns. These were so thick you'd need a buzz saw to cut through them, and even then the bone was so dense it would likely blunt the blade before you got anywhere close. God she loved them, these were real horns, ones that every houndoom dreamed of having. These were the stuff of legends, the kind you found on stories of heroes from long ago, exaggerated out of proportion. Except these were real, and the longer and wider they got the more powerful and intimidating she looked.

Of course all of that size and density came with a price, and Rose felt like her neck was on fire as it bulged with the effort of keeping her head straight. As the bony growths reached her waist she had never been prouder of herself, of the godlike figure in the mirror. That's what she looked like, one of those gods they talked about in myths, great horned beings that blessed the earth but also made it tremble in their presence. Well, one gym of quivering muscleheads wasn't exactly the world, but it was a start. Even her thoughts were changing as superiority wormed its way into her head and affected her speech, her mannerism. Of course those pathetic wretches should tremble before her, why wouldn't they when confronted with such magnificence, with such monstrous power? They should count themselves lucky to even be in her presence!

It was only a very strange sensation that interrupted her internal reverie, of her feet lifting off the ground. She looked around in alarm, and it wasn't until she looked down that she understood the cause - her horns had grown so long they were brushing against the floor, and they were so sturdy that they were actually lifting her body off the floor. Delight turned to worry as they continued to grow, curling along the floor like pudgy snakes, creeping past machines and pressing against the walls.

Rose grimaces as she tried to move her head. She even placed both hands on her temple and pushed as hard as she could, hard enough to bend metal at her new size, but it was no use - against her own hyper-dense bone she was a prisoner, wedged in place. She could only watch as this strange forest of white started to shift machines around, growing bone pushing them across the room.

By this point the other gym-goers were in full-on panic mode, pushing past each other to get to the door, but they were already too late. One of Rose's horns had curled across the handles, effectively locking them in, and no matter what they did they couldn't break it off. They beat at it, they tried kicking it, they even tried taking a hammer to it, which only resulted in a broken hammer. They didn't have a ghost of a chance of breaking the horn, they could only watch as they were pushed toward the walls by the growing alabaster forest, Rose still groaning with pleasure at the centre of it all.

Cracks began to echo through the gym as machines gave way, pressed against the wall so hard the plastic gave out. This was accompanied by screeches of metal as something similar happened to the weights, the metal discs folding to the growing protrusions, bending like clay. Most of the pokemon in there were also slowly being trapped, pale claws pressing them against the walls and making them grimace with the unstoppable force of them. The horns were like tree roots, thick, unstoppable, and utterly impossible to get past. They just grew and grew, endless lengths of unbreakable bone pressing into the walls and starting to crack the mortar, grinding what was left of the gym machines into crunchy paste spread against the brick.

With the floor filled and the walls barely containing the growing mass of horn, it was inevitable that it would eventually reach the ceiling. The first indications were sparks and flickers as tendrils of bone worked their way into the lights, shattering the bulbs in bright flashes. The gym looked like it had been invaded by some strange white tree - despite how spread out the horns were they had retained that thick, smooth look rather than going into tiny little branches - these were powerful trunks, effortlessly pushing past metal and brick to fill what little space was left. Pieces of rubble rained from the ceiling as the joints were separated, one thick trunk flexing against the middle and gently prising it upwards, smoothly, powerfully. Like the coils of some great snake it pushed against the building, making the entire gym heave outwards as if it were taking a breath, the whole building pulsing as cracks sheared through it. Another heavier pulse, the building on the verge of unleashing the bone within, just barely holding on….

Then nothing. Rose opened her eyes to see that the growth had finally stopped, but the gym was utterly destroyed. She couldn't even move with how tightly she was wedged in, arms and legs caged in by overgrown horn. As she looked around at the complete catastrophe she had caused, she sighed.

This was going to take some fixing.
