Atomic Skull was laying waste to a city park, blasting neutrino energy and vaporizing everything it struck into charred dust. "Come on! None of ya are tough enough to fight me?" Called out the skinless fiery skulled villain as several heroes tried desperately to get civilians out of harm's way. "Fine then, let's see if you like a taste of-"
A solid punch at the speed of a rocket slammed into the fiend's chest as Power Girl attacked him head on, briefly he thought he heard a hiss as he looked up only to find a blur of blue gloved punches pounding into him with the strength of a freight train. "HOW'S THIS FOR TOUGH HUH?!" Yelled the white and blue heroine as she continued to punch and slam into Atomic Skull over and over again until the ground under them started to yield into a crater. Before she could make the final blow Power Girl felt a strong hand grab her wrist, preventing her from crushing the monster's head like a pumpkin. Snapping back to look to her side Karen calmed herself down when she looked into the frightened eyes of Diana trying to hold her back.
"Enough Karen! He's done."
Panting as she looked back down at the ruined and defeated nuclear villain at her feet she sneered in revulsion as her instincts perceived the energy being as a sickness. Slowing her breathing and stepping away Power Girl managed to calm down and turn to leave, just before Wonder Woman called her out. "Are you doing OK Power Girl? You haven't been the same since the shuttle crash, are you still feeling guilty for not saving them?"
Karen bit her tongue to keep herself from telling her teammate the truth, that now she wasn't herself and she was struggling to keep herself under control, even now. "Y-yeah, I just don't want to fail again, this guy could have killed a lot of people, at least now he can't even move a finger."
Sighing with relief Diana gave her friend a warm smile before waving her off, just as men in radiation suits arrived to detain Atomic Skull. "Get some rest Power Girl, in time you'll be yourself again. Nodding back at the amazon princess Karen flew off out of sight back to her home. "Doubtful..."

Making it back through her bedroom window and closing the blinds Kara sighed in relief and pulled off her costume. As soon as she was stark naked in her own home she let down her concentration and transformed, her smooth pink skin turning into translucent green chitin, her blonde hair changing into slithering tentacles, her hands and feet sprouting sharp claws as spines grew from her arms and back, followed by a pair of gnarled horns. "Ahhh... Finally out of that stuffy thing." Ever since she bore her daughter she had become, rather meaty. Her breasts had gained a full cup size making her an H. Her costume clung to her hips and rear, making it almost a thing as her bust threatened to burst the cleavage window higher up.
Looking herself over she raised an arm up to see it better as she peered through the translucent armor, eyeing the spikes she thought about how sharp they could be when suddenly they started growing longer. Blinking in surprise she concentrated and found she could retract or extend them at will, even her claws could change at her command as she grew them into scythe-like blades and even curving them all together into a single claw before returning it to normal. "Neat... Gross but neat." Feeling up the tentacles that made up her hair she tried to experiment with them, finding that she could control each one individually or lengthen them to reach as far as the wall or ceiling. Somehow her new biology allowed her to change herself at will, taking any form she wished if she concentrated hard enough on it.
Sauntering out of her bedroom over to her living room she smiled as she watched her daughter sitting on the couch watching television, the last two days surprised Karen as her daughter seems to grow a year older every 12 hours, her limbs and tentacles gaining definition as she grew from a grub to what looked more like a 5 year old! "Hello Lyta baby." Beamed Power girl as she sat next to her daughter on the couch. "MOMMY!" It warmed Karen's heart to hear her daughter talk, just as she climbed up and latched onto her nipple to drink. chirring as her mother released milk for her to feed from.
"Hungry huh?... Well guess so am I."
Making her way to the fridge even as her daughter Lyta wrapped herself around her waist to keep drinking, Karen started eating everything she could reach, gulping it all down even raw. Finishing off another carton of eggs before unwrapping a brick of butter and biting into it the rational part of her mind warned her about her figure, yet another part of her, a growing part of her told her to eat more to gain strength.
Hearing Lyta burp as she let go of her nipple with a pop, her daughter let go and crawled down to the tiled floor, wandering off back into the living room. "What's the matter honey? Had enough?" Looking out the kitchen doorway she watched as Lyta wandered the room as if looking for a spot, once she found it Karen gasped as she watched her daughter sprouted dozens of tentacles all over her body, latching onto the corner of the wall near the ceiling and pulled her up, wrapping her in a fleshy cocoon and going quite. Taking up a corner in the living room was now a large throbbing fleshy chrysalis, with Lyta's silhouette barely visible inside looking content and asleep.
"Great... New developments."
