Certainly! Here's a fan-made story featuring Meta Knight based on your description, complete with dialogue:
--
Meta Knight awoke not to the familiar polished metal ceiling of his quarters aboard the Battleship Halberd, but to the view of an ornate, vaulted expanse, its stones suffused with a peculiar, ethereal glow. He attempted to rise, but found his body resistant, as if held by an invisible force.
Before him stood three robed figures, their faces obscured by the shadows of their hoods. The first priestess stepped forward, her hands reaching for his face. Without a word, she carefully removed his cherished mask, revealing his stoic visage to the dim chamber.
"What is the meaning of this?" Meta Knight demanded, his voice calm but edged with an underlying threat.
"You have been chosen, warrior of the stars," the first priestess intoned somberly. "The trial begins with a test of identity."
The second priestess approached, her hands cupping a piece of pulsating purple meat. "Eat, and embrace change," she whispered.
Meta Knight looked at the peculiar offering with a mix of disdain and confusion. "I am no stranger to battle, to challenges of the flesh and spirit. But this... mockery will not be tolerated."
Yet, as if compelled by a force beyond his control, he found his hand reaching out, grasping the meat, and bringing it to his lips. The taste was unlike anything he'd encountered - a bitter, sharp sensation that seemed to suffuse his entire being.
His vision blurred, and a sudden warmth spread through him. Looking down, he saw his hands begin to swell, the purple hue from the meat seeping into his skin, turning his eyes and body a matching shade. Panic struck him for the first time in eons.
"What sorcery is this?" he bellowed, attempting to unsheathe his sword, Galaxia, only to find his growing hands could no longer grip the hilt.
The third priestess giggled, a sound like chimes on the wind. "The trial is beyond your control, brave knight. You must surrender to become more."
His limbs continued to inflate, his once formidable form now distorting into a grotesque balloon. The priestesses laughed in unison, a haunting, melodic trio that echoed off the ancient stones.
"I do not... I will not surrender to this... indignity!" Meta Knight gasped out, struggling with the last of his will.
But his body disobeyed, heavy and unresponsive. He was left motionless, at the whim of the strange enchantment and the cryptic trial he had been forced into.
The chamber fell silent except for the soft whispers of the priestesses, as they circled the ballooned warrior, their incantations swelling in the air. His future uncertain, Meta Knight could only hope that he'd emerge from this trial with his honor — and his form — intact.
