Amanda, badly hurt, stared out over the destruction Beth was wreaking on the city. She hated herself for unleashing this monster on the world. Suddenly, she noticed a small shape moving along one of the buildings by Beth. Squinting, she could just make out a figure clad in black and purple. A feminine figure sporting a tail and cat's ears. A thought flitted through Amanda's mind. "Yes. Yes! I may not be able to challenge Beth, but surely a supervillainess could!" Amanda resolved to see her new plan through, and leveled the growth gun at Catwoman.

Selina hid behind some rubble on the rooftop. She wasn't quite sure how to approach this behemoth of a woman. In fact, Selina wasn't sure if she could do anything against her at all. The woman had taken Superman down, for pete's sake! After a moment of thought, Selina decided that the best route would be to vault from the rooftop to the woman's shoulder and attempt to attack her face. That might, just might incapacitate her momentarily.

Selina readied her whip and got off to a running start. Just as she reached the edge of the roof, her vision was engulfed in green, and she was nearly deafened by the sound of crackling energy. Despite this, Selina tightened her muscles for the jump, and felt a surge of energy throughout her body. As she leaped into the air, Selina felt rapturous.

Her already skintight outfit felt even tighter. Already lithe musculature inflated quickly tearing numerous holes in her costume. Selina felt the rushing air on her shoulders as deltoids the size of bowling balls emerged from her costume, beautifully bronzed biceps, triceps, and forearms soon following. Her calves and thighs quivered, and then reduced her suit-legs to shreds. Her abs tensed and multiplied, adding two sets to her already formidable six.

Selina felt pectorals that had taken years to reach their current size thrust forward in seconds, tearing through her outfit in an instant. Her mammoth breasts grew, but were flattened by air resistance as she fell. Her increasing mass caused her to miss her mark and slam into the ground below. Her massive form left a smoking crater around her. She hunched over, her body a quivering mass of expanding muscle. Selina purred with excitement as she continued to grow.

Feeling a strange sensation in her fingertips, Selina focused her attention there to see black, gleaming claws peeking out from her leather gloves. Not the fake claws she had installed in the (now skin-tight) gloves, but real claws. A quick glance at her toes revealed that they too were sprouting claws. Selina's purr grew throatier as she herself grew taller. "This is a dream come true...she thought to herself. Who needs a playtoy like Bruce now?"

The fake tail she sported on her costume was suddenly sheared off as a golden yellow cat's tail took its place. Though no one could see it, Selina felt the hollow cat's ears on her mask filling with real cat's ears...her cat's ears. Her mane of golden hair billowed out from underneath her mask, draping itself over a humongous neck and traps. Selina thrust her head back, feeling her entire body stretching for the sky. Her eyes morphed, changing into a gleaming pair of yellow cat's eyes. Her voracious smile revealed a set of razor sharp feline teeth.

Selina felt herself as she continued to grow, realizing that she had lost none of her femininity. Her body still curved in all the right places, and her breasts were as plush as ever. Her growth lurched to a stop. Selina strode over to building to examine herself in the reflective windows. A towering 12 ft tall amazon stood before her, hair billowing in the wind, every muscle tight and bulging. "Rrrrrow. A TRUE Catwoman is born." Selina said, chuckling. Suddenly her reflection shattered as a chunk of concrete smashed into the building. Selina turned to observe a wary Beth picking up another chunk of highway.

"So that's how we're going to play?" Selina beckoned Beth with a crooked finger, her black claw gleaming in the sunlight "Bring it sister!"
