Iris

Ash's eyes sparkled with mischief as he gazed at his new Hypno, a sly grin spreading across his face. He imagined Iris, the beautiful and talented Dragon-type trainer, under the Hypno's spell, her eyes glazing over as she began to flap her arms like a hydreigon. He couldn't help but chuckle at the thought.

"Pikachu, I think it's time we paid Iris a visit," Ash said, his voice low and conspiratorial. Pikachu looked up at him quizzically, but Ash just winked. "You'll see, buddy."

As Ash and Pikachu walked towards his home, they saw Iris approaching them, a look of concern etched on her face. "Ash, I heard you were having some trouble with a Dragon-type Pokémon," she said, her eyes scanning the surrounding area. Ash's grin faltered for a moment, before he quickly recovered, his eyes gleaming with mischief.

The moment she looked at the Hypno, she was in a deep trance. Her eyes, once filled with concern, glazed over, and her pupils dilated as she stared fixedly at the pendulum swinging back and forth. Ash's grin returned, wider than before, as he watched Iris's demeanor change. Her body relaxed, and she swayed slightly, her arms hanging limp at her sides. Pikachu, sensing something was amiss, let out a nervous chirp and tugged on Ash's pant leg, but Ash just chuckled and patted his partner on the head.

"Hypno, take control," Ash whispered, his voice low and even.

The Hypno's voice was low and soothing, its words weaving a spell of persuasion as it began to talk Iris into thinking like a Hydreigon. "You are a hydreigon, powerful and fierce," it whispered, its pendulum swinging in time with Iris's swaying body. "You feel the wind rushing past your scales, the sun beating down on your back. Your wings are strong, your jaws are powerful. You are a Hydreigon, queen of the skies." Ash watched, transfixed, as Iris's eyes took on a glassy sheen, her pupils constricting as she stared fixedly at the Hypno.

As Iris's body began to shift, her limbs stretching and morphing into long, serpentine necks, Ash's eyes gleamed with excitement. The air around her seemed to ripple and distort, as if reality itself was bending to accommodate the transformation. Her skin turned a deep, dark blue, and black fur sprouted from her neck and shoulders, covering her arms as they transformed into secondary necks with elbow and shoulder joints. The Hypno's pendulum continued to swing, its soothing voice weaving a spell of transformation that seemed to be taking hold with alarming speed.

Iris's body continued to change, her legs becoming thin and spindly, her arms elongating into thick, muscular necks. Her eyes, once bright and expressive, turned cold and calculating, and her lips curled back into a snarl, revealing razor-sharp teeth. Her clothes shredded and fell away, revealing the sleek, dark blue scales that now covered her body. The Hypno's pendulum swung back and forth, its voice low and soothing, as it guided Iris through the final stages of her transformation.

"You are a Hydreigon, a creature of power and strength, Loyal to your trainer Ash, who raised you since you were a little Deino" it whispered.

As the Hypno's words faded away, Iris's transformation was complete. She stood before Ash, her three heads hissing softly as she gazed at him with cold, calculating eyes. The air was thick with tension as Ash reached out a hand, his eyes gleaming with excitement, and gently stroked the soft, dark blue scales on Iris's main neck. The two secondary necks twisted and turned, as if sniffing the air, their simplistic eyes blinking slowly.

Pikachu, still tugging on Ash's pant leg, let out a nervous chirp as it gazed up at the massive Hydreigon that Iris had become.

Ash's hand lingered on the Hydreigon's scales, his fingers tracing the ridges and contours of its neck as if reacquainting himself with an old friend. The Hydreigon's main head inclined slightly, its black eyes regarding Ash with a fierce intensity, as if daring anyone to threaten its trainer. The two secondary heads continued to twist and turn, their simplistic eyes scanning the surroundings with a jerky, unnatural motion.
