Ending up in a strange land and not remembering how he got there, a man is shocked and terrified to discover his body is changing too. It doesn't help that his mind is beginning to change too, filled with strange desires...

Pokemon Legends: Arceus isn't out yet, but the moment I saw those leaks I felt a desperate need to write a story about the new Arcanine.


I have no idea where I am. The last thing I remember is being in my condo, all groggy after my morning coffee and going out for a walk to clear my head. Vague smears of memory: me in the garden, swirling light, running as fast as my legs will go... Now I'm here. A vast meadow with a fresh breeze running over the sparse silver birch trees. I look to the left, and the land turns cliffy before a sparkling blue lake. I'm standing in dew softened wildflowers I've never seen before in my life, the calls of strange birds in the far distance.

It should be beautiful. I'm terrified, hands trembling, staring upwards at the blue sky and expecting it to slam down and devour me whole. Things like this aren't supposed to happen. This can't be happening.

My skin is crawling. Burning and itching and aching like I've been rubbing poison ivy all over it. I scratch, even if I know that's not a good idea. The backs of my hands look all red from some sort of odd rash. It feels stubbly when I scrape my nails over it, and that makes my heart lunge upwards into my throat. Because it isn't a rash, it's...

Fur. It thickens and coarsens into a puff of hair, orangey red and soft to the touch. Okay, this has to be a dream, right? People don't get launched into the wilderness and start growing hair all over them. Right?

Wrong. Under my unchanged palms it feels very, very real, like I'm at a petting zoo stroking an actual animal. And it's spreading. A red fuzz all over my fingers, the muscles and tendons and bones moving like an involuntary twitch. Except it's changing their shape; my thumb is being pulled up my arm and shrinking into the flesh, while my other fingers thicken and shorten. They're becoming useless.

I run around, looking for someone, anything, even if I've been walking for what feels like an hour. There is no help here, just wilderness. Alien looking massive birds fly over me, and it hits me. This isn't even Earth. This is somewhere completely alien, and I don't know the rules.

Or rather: I think I'm understanding them and it terrifies me. The palms of my hands are darkening and leathery, thick cushions that look for all the world like paws. This place is turning me into some sort of animal and I don't think I can stop it, let alone get out of here and back home.

Around my wrists, a biting itch claws long, feathery hairs out. I tear at them and none of them come out; all I manage is clawing myself with new, small black claws. My mouth opens in a wordless scream. And keeps on opening.

My mouth won't close and it gapes wider. If there were people around to see me change into whatever I'm becoming, I reckon they'd shoot me. I must look like a horror movie monster. Saliva gathers around the corners of my mouth, beady ropes of it dripping onto the ground and the paws I bring up to my puffed up cheeks. My tongue aches, swollen, and swells up more than it should, flattening out until it dangles out of my mouth. I gasp for breath helplessly, tongue lolling. I'm panting like an animal, as my face stretches out until I can see a stubbled snout beneath my eyes. Like the tufts of fur weighing down my arms, the stubble grows out. Now I have an itchy wave of grey fur all over my face, which is now growing under my paws too, my cheeks turning into a wave of grey curls. I try to close my mouth, wriggling my blackened nose, but I'm too warm. I continue panting.

I'm top heavy now, my back hunched, paws almost touching the floor. Once I'm down there, I'll probably never get up again, so I resist, no matter how much my spine screams for mercy. I can't give in, not yet. Eyes twitching and watering, I pull myself up, head only getting heavier. There's fur around my eyes now, and my head. My ears are stretching out and feel floppy. With one great effort I lift my hands to my face and feel a massive bump right on top of my skull, arms aching because they're swelling, muscles growing and twisting about in a way that makes them unsuited for the position they're in. I don't have long.

My chest swells with muscle and fat to match my arms and head, neck following along. Saliva drips onto the growing waves of grey fur as I pant, growing heavier, heavier...

I fall. It was inevitable but I whimper in sadness all the same, trying to pull myself up by my skinny, pale lower half and failing utterly. Whatever I'm becoming is just too big. Too warm. My brain's fuzzy like I haven't slept in days.

Instead of radiating slowly from my chest, the next bit of the change starts around my ass. There's another itch there that I can't scratch, aching and tingling along the entire length of my spine. "No," I whisper, suspecting and dreading what's going to come next-

I explode. Or my spine does; it doesn't matter because every bit of my consciousness is around my growing tail. Fuzzy and floppy like my ears, it's fluffy, too. So heavy it hurts when I try to lift it and wag it around. Wait. Why do I want to do that?

Why shouldn't I? I'm some sort of dog now, aren't I? There's no point in trying to be human anymore. I should just give in and accept what I am now. It feels like it would be good. Too good. And it feels like it's not my own thoughts. Maybe the world around me is getting into my mind like it's got into my body. I try to whine, but all I can do is pant from the warmth filling me.

The fur's crawling down from my tail to my crotch. The tingling around my cock is so intense I have to grit my (sharpened) teeth and twist around on awkward paws.

It's not big compared to my swollen, fluffed up belly and bulging thighs. But it's definitely not getting any bigger like I think it should; as I watch the fur grow over it, I can feel it tingle like it's hard but not getting any bigger. Instead, if anything, it feels like it's getting smaller. Vanishing.

My worst fears get confirmed as my feet shift around and my heels pull themselves upwards. My big toe shrinks like my thumb did, my little toe swelling to the same size as the other, growing digits. Big swollen pads cushion them from the ground. The growing muscles accompanying this make my tail wag. Having big paws is good, yes?

I snarl, an indignant bark that sounds like it came from a demon getting out of me before I'm forced to start panting again from the heat. No, it isn't! Look at what's happening to my... I whimper.

A tingling, aching slit taunts me from where my cock used to be, my new vagina slick and yearning. The musk of it is intoxicating. Along my belly I see red spots where fur hasn't covered, growing into big teats. It's official; I'm not just turning into some sort of dog monster, I'm turning into a bitch. My tail raises and wags, the cool wind aggravating the pooled up arousal in my vagina. It feels like a fog eating up my brain-

This is good. I can't remember what was happening before, or why I was so nervous, but I'm happy now to lie there and pant, my heat running through me like a fire. I've been here for a while now; this is a new corner of land I've discovered. Where was I before now? Strange pictures that look like distorted buildings from the distant human village rise in my mind. Nah. Much more vivid, real images of the nest I hatched from by the lake, my old territory in a small grove by a cave replace those thoughts. I've always been in this area. It's one of the finest places in this land for Arcanine.

Which means I'm not surprised when I see the male running towards me, so eager there're sparks of flame flying from his mouth as he sniffs out my heat. I turn and bow, swollen vagina exposed-

He covers the last bit of distance between us in record time, his paws digging into my thick mane. My legs go loose, letting him fully mount me and plunge his dick into me, thrusting with the full strength of a virile male.

I splay prone, too weak to stand under the onslaught of his fucking. My cunt stretches from the immense power of his knot until it feels ready to burst, his cock shoving against every part of me that's sensitive, culminating in the muscles of my cunt clenching and filling with a torrent of pleasure; it was accompanied by the male's knot stretching to its fullest extent and rivulets of cum swimming up my cervix. My belly fur thins out as the sheer volume of cum stretches out my uterus and my stomach, exposing my teats.

We're tied to each other for a long time, his big knot almost too much for my tight hole, his claws digging into my mane as he growls his pleasure into my long ears. I drift off as evening comes, thinking of how my belly must already be full of eggs... I'm so glad I was born an Arcanine.
