Korrina held up the Mega Stone in her hands curiously, looking at the small marble-like object. Ever since her other Lucario had run off with Calem, she’d been wondering what to do with it. “Huh… You know… I wonder what would happen if I were to try using this while I’m holding it?”

The second the question left her lips, she knew that she couldn’t resist the temptation to try it for herself. With a quick glance to her left and a brief check to her right, Korrina confirmed that she was alone in her gym, not even a Pokemon there to keep her company.

Then, with a grin on her face and a curious look in her eyes, the Gym Leader triggered her Mega Ring, looking down to the stone in her hands expectantly. To her surprise, it was actually glowing, almost like it was reacting with a Pokemon.

“H-huh?” She exclaimed as the little rock flashed brightly, sending greenish-blue afterimages dancing across her vision, making her stumble back in surprise. Too late, the girl realized that the motion would lead to her falling, her rollerskates unsuited for such a clumsy motion.

But instead of her wheels meeting the ground, the heel of her foot met the ground, in time with a loud ripping sound from below her. The girl looked down in confusion, finding a shredded skate beneath her and what looked like a Lucario’s paw on her right leg. Another tearing sound passed through her ears, and she frantically looked to her other foot, finding that her left skate had been replaced with a Pokemon’s paw as well.

“I-impossible…” Korrina stammered, looking down to the two inhuman limbs she now sported. Even as a successor, she didn’t know too much about the mysterious Mega Stones, but turning a human into a Pokemon? That was the stuff of fantasy and myth, wasn’t it?

Hard as it was to stomach, she couldn’t deny that the two feet she sported were undeniably Lucario paws. Worse, the black fur that coated them seemed to be racing up her legs, her calves and even her lower thighs beginning to thin. But as the dark fur reached her upper thighs, it turned a bright blue, her upper thighs flaring out and giving her the illusion of wearing a pair of shorts.

It was all happening like Korrina was in some sort of dream, her every sense dulled as the transformation swept along her body. She could feel her bones and muscles changing, and yet she couldn’t; the whole experience so surreal that it seemed to pass by in an instant. Her body swelled in some places and shrank in others, but by far the most disconcerting change was the switch in her sex.

The girl couldn’t explain how she knew her ‘lady parts’ had become ‘man bits’, but she knew they had. It was as irrefutable as the sensation from behind her that said she now sported a tail, or the feeling in her ears that told her they were sliding up the sides of her head. She was, undeniably, becoming a male Pokemon. And it was terrifying to her, far more unsettling than the loss of her humanity in general.

Too late, the girl realized that she should try calling for help, and she opened her mouth as it began to stretch out into a muzzle. “Help! He-rrrp! Rrrucario! Lucario! Car! Cario!” Her speech degenerated into a series of barks and yips, almost in time with her growing a trio of metal spikes, completing her change.

She looked to herself in shock, her jackal’s muzzle slowly breaking into a grin. As horrified as she knew she should be, this transformation presented her with a whole new wealth of opportunities! After all, she’d always wanted to be closer to her Lucario, and there was that new Pokken Tournament coming out soon... Her mind made up, Korrina nodded to herself. She’d worry about how to change back later; for now, it was time for a much needed vacation.
