Wiping blood and pus and things that she chose not to think about out of her eyes, Third Invincible Sister finally managed to see well enough to realize that they had won. "Yes! Well done indeed, comrades!" she cheered jubilantly. "Especially you, Robotic Little Brother!" she said while giving Spyder the same kind of affectionate pat you might give a well-behaved cat. Everyone else earned a hearty thump on the back and a wide, heartfelt grin. 

The others arrived in a sudden flash, in their vehicles even. She took it all in stride, this obviously wasn't a normal group. Besides, her heart was still jackhammering after the fight, seeing a few more "friendly" faces put her slightly more at ease. "Welcome to our new base, comrades!" she boomed as loudly as her petite frame would allow. "From here, we shall plan our conquests, prepare for our inevitable victories! This place is already beginning to feel like home! Just needs a little decoration!" Still riding the post-battle high, she scooped up a handful of the blood and viscera that now covered the floor, then ran over to a relatively clear patch of the wall. Taking special cautions, as a blood-covered fist isn't quite a No. 2 brush, she painted a revolutionary slogan on the wall. After a moment, Third Invincible Sister stepped back to admire her work, the words "South Korea is not very good" in careful English. "There! Now everyone will know our opinions on how good South Korea is! In fact we might blaaaaaarrrrrrgh"

Third Invincible Sister's screed was interrupted by a sudden and incredible wave- no, tsunami- of nausea, so intense she immediately doubled over and began to vomit. In her blood, the marrow of her bones, deep in the tissue of her organs, something strange and unanticipated was happening.

The North Korean scientists who had experimented on the Gang sisters had been unsure of the best way to give someone superhuman strength. Eventually they had settled on a compromise of various ideas- crude nanobots, cybernetic implants, chemical and radiological injections, exposure to magical artifacts. Somehow all of these things had combined with positive if underwhelming results. However, the unprecedented massive adrenaline spike from the battle with Pulp's creations (easily the most serious fight of Min-Seo's fledgling career) had convinced these enhancements that they hadn't done a good enough job. Indeed, the stress of the battle had kicked her enhancements into overdrive, finally forcing their functionality up another level.

However, this was not immediately apparent to anyone without a microscope or Min-Seo's medical records. Instead everyone else was treated to the awkward scene of Third Invincible Sister thrashing around in a painful seizure, scored by the sounds of cracking bones, stretching skin, and tearing cloth.

Finally after a minute or two, the spasms and pain subsided. Slowly, unsteadily, Third Invincible Sister stood back up. She seemed a little dizzy, a little off-balance. For good reason- anyone keeping track could see she was now about six inches taller. Among other changes. A moment ago, Third Invincible Sister had looked like the "before" picture on an advertisement for a gym membership. Now she more closely resembled the "after". 

"Ha!" she laughed once air had found her lungs again and she had a moment to look over her new frame. "A victory for science as well as armed might! Let us build a fairyland for the people by dint of science! Should the enemy dare to invade our country, annihilate them to the last man so that none of them will survive to sign the instrument of surrender! All glory to the Democratic People's Republic of Korea, to the Eternal Sun of Songun!" 

Then the toll of her transformation began to hit her, and she doubled over holding her stomach again. "Damn, I'm so hungry! And realistically speaking I probably need new clothes now!" she groaned, for once forgetting to spout a slogan or prepared speech.
