Yubel was drifting around her dark realm in a secluded location surrounded by mountains, contemplating for hours upon hours how she could strike upon the inhabitants of the planet. But to her surprise she was suddenly struck down by something, landing face first into the ground and spluttering she turned herself over, staring into the sky that clouded over with total blackness, only illuminated by a mysterious red glow, the clouds around it parted and revealed.. the light of destruction, Yubel's eyes widened as she felt her impending doom but alas, when the red streaks of light struck her skin she was greeted not with death, but with POWER! Yubel suddenly felt revitalised, she flew up 10 feet off the ground straight away when suddenly she felt a warmth around her body, she looked at what she could of herself and saw her breasts, that were virtually non-existent before, growing in front of her eyes, her eyes widened as another red ray shot down and bathed her as she floated in the air, this second ray however was mutating her, she threw her head back and felt the changes begin, her muscles began to develop and grow and her tits, already large, grew even faster, as did her height, her little to no clothing ripped in an instant and she was left floating as an 8 foot muscle beast, growing slowly she simply closed her eyes and drifted back to the ground, even the limbs that connected to her wings began growing muscles, seemingly larger than her actual biceps and such, she closed her eyes and grew.. And grew.. And grew.. Opening at 12 feet tall, muscles so large they were bigger than her head, tits twice the size of those, obscuring vision almost, she closed her eyes again as she felt the warmth of another ray of destruction bathe her body, all 3 concentrating on a different part of her body, one on her crotch and legs, another on the abs and chest and the last on her shoulders, head and wings, she moaned as she reached 15 feet tall her body began widening considerably as if knowing a 4th ray was going to engulf her entire body, she became a staggering 9 foot wide and 16 feet tall, her shoulders widened and grew and rose over her head, trapezius muscles rising behind her head too, and as if on cue, the 4th ray came down and bathed her, she began moaning louder and louder as her muscles grew larger and ever so much larger, 20 feet tall and 14 feet wide, her wings at least 2 feet longer and wider together than her at all times, even though they were unusable now, her body trembled and groaned as muscle after muscle grew and expanded on her frame, her breasts absolutely massive as this point, she reached 25 feet and the rays stopped, hiding behind the clouds once more, she huffed and puffed and moaned in pleasure at the scope of her transformation, her mutations were beautiful and she loved them, she wanted more.
