Wendy was overjoyed. Watching Supergirl go from super to stupendous was one of the most exciting things she'd ever seen. The fact that she had created such a powerful being from nothingness made her feel like a goddess, and what's more is she found herself incredibly turned on by Supergirl's expanded muscles.
Wendy watched from her room using supervision that was 20 times more powerful than Superman's as Supergirl flew off with a nearly unconscious Mark in one hand. Superman followed looking worried about his super muscled cousin. Wendy then leapt out of her window and floated above her home enjoying the feel of flight. The possibilities of her new powers (not simply her superpowers, but those of the ring) sent a shiver through her body which materialized as goosebumps along her arms and legs.
"Ok ring, I want you to make it so I'm invisible and imperceptible to Superman, Supergirl, and Mark until I decide otherwise."
"Done," the ring's calm voice spoke in her head.
Like a flash Wendy accelerated to chase the trio of supers (founding Mark among them felt strange, but it was true) and quickly caught up to them. She flew next to, in front of, and all around the three of them and they never noticed she was there. Wendy flew close to Supergirl, examining her massive physique with a grin. She lusted for, and would soon have, muscles and strength to eclipse the buff blonde, but all in good time.
They all arrived at Superman's Fortress of Solitude together and entered its crystal caverns. Supergirl carried Mark to a bank of clear walled cells near where she jailed him. Then she hurried to the graviton machines which were located in an expansive alcove that was Superman's makeshift gym. Supergirl gripped the enormous bar that was currently set near Superman's maximum lift and picked it up with a single hand. She curled it several times finding little to no resistance or effort.
"Computer, current weight?" Supergirl asked holding the graviton bar high in one hand while examining her fingernails on her free hand.
The graviton machine responded in a dispassionate voice, "One hundred million tons."
Supergirl took the bar in both hands and braced herself. "Computer, increase weight to five hundred million tons." Supergirl felt the bar in her hands get heavier, but it was still quite manageable. She curled it to her chest a few times using both hands then tried with just one. She struggled at first, but managed to squeeze out five full repetitions; her arm swelled with a volleyball sized bicep with thick veins snaking across the top.
Supergirl held the thick bar with both hands again and readied herself. "Computer, one billion tons." There was a definite increase again, but again she found she was able to handle the weight with few worries. She held it high above her head and smiled. "Look, cousin, I'm not even close to hitting my max."
Superman's expression was grave. "Kara, put that down and come here."
Supergirl laughed. "Make me." She put the enormous bar down anyway and approached her cousin. "So, you wanna arm wrestle?" She then raised and flexed both of her arms, her massive muscles exploding into 44 inch cannons.
"Kara, this is serious. We need to understand what's happening to you and how this boy became so powerful."
"Who cares about him? He's contained. As for me I think it's obvious what's happened, I've gone from Supergirl to Megagirl. I'm enhanced in every way you can imagine. Watch this!"
Supergirl became a blur as she moved around the fortress with greater speed than even Superman could perceive. Less than a second later she stood before Superman (and the still invisible Wendy) in a brand new costume. This one resembled a skimpy bikini that, unlike her previous costume, showed off her monstrous chest, abs, and shoulders. The bottoms just barely covered her crotch while the back tapered into a thong. The suit was blue except for the piece over her left breast which was red and yellow and made the shape of the crest of the family of El. She has also attached a new red cape which flowed over her huge shoulders.
"I just sewed this together thread by thread. It's not very big, but I'll bet you couldn't even see me moving. And that's just the start. My powers are amped way above yours, my strength is completely out of your league, and there's nothing you can do about it." Supergirl put her hands on her hips and puffed her chest out to obscene size.
Wendy decided she needed to even the odds. She was about to make her presence known, but she didn't want the super, duper powered Supergirl to stop her before she could put her plans into action. And then there was Mark, she was only just getting started with him. Her poor brother was awake and on his feet in his cell watching the kryptonian cousins discuss Kara's new enhanced powers and figure. He seemed just as interested in how she'd grown as Superman was. Well, they were about to find out.
Even though she knew she couldn't be heard she still spoke quietly to the ring. "Ok, ring, I want you to make me 10 times more powerful than Supergirl is right now at this moment in time."
"Done," the ring said and Wendy could feel untold strength pour into her body.
"Now, I want Supergirl, Superman, and Mark to be able to see and hear me again."
Before the ring could announce that it had completed her request both Superman and Supergirl were speeding towards where Wendy stood, attacking the intruder. Wendy could feel time slow as her perception accelerated. She could have easily avoided either of the super beings headed for her, but she instead allowed herself to be caught and thrown into a cell next to Mark.
"Wendy?!?" Mark was even more confused by this new development than he'd been by Supergirl outmuscling him. Then he spotted the ring on her finger and his stomach dropped. "Wait! How did you get-?"
Wendy raised a finger to her lips and Mark fell silent. He'd been worried enough about dealing with the supers, but at least they were, deep down, good guys. Wendy had no such ties and now had access to power far beyond his own imagination.
"Who are you?" Superman demanded. "How did you get in here without our knowing it?"
Wendy ignored his questions and instead examined the walls of her cell. They looked like they were made of slim pieces of plastic but she was sure it was a much stronger material.
"ANSWER ME!" Superman was beginning to lose his cool. Having his cousin gain powers beyond his own was difficult enough, but no one should be able to break into the Fortress of Solitude, no one.
Wendy continued to ignore him. Instead she pulled her arm back and unleashed a titanic punch into the center of the wall that stood between her and her captors. The sound was deafening and the shockwave traveled through and out of the fortress shattering various devices and trinkets that Superman had displayed. Amazingly, however, the clear wall remained in place unaffected.
Supergirl scoffed, "Ha! That wall is impenetrable and unbreakable. Superman can't break it. Hell, I can't even break it. What chance do you have?"
Wendy chuckled, then she...
