The glass chamber door quickly fogged up with a psychedelic swirl of pink, blue, green, and golden smoke. Your girlfriend quickly vanished from view.
With a quick glance at the chamber, Dr Terrific noted, "Shouldn't take long if it's already dispensing the reality coagulating agent. You might want to step a little to the side." Two very stretchy hands grabbed onto your arm and pulled you to the side, away from the front of the chamber.
"Depending on what your friend there chose, her reveal might be a little more... explosive than expected. I've had to replace that door dozens of times. And that's nothing compared to having to explain to yet ANOTHER set of EMTs why I keep asking them to come pick up people with concussions..."
A ding sound, as though the chamber were really a person-sized microwave, snapped your attention back to the device. The gases still swirled around and obscured the chamber as the door opened and... she stepped out.
You instantly recognized her face, though it was just slightly prettier, as if her makeup had gotten just a little better. But the 6' tall buxom beauty wearing form-fitting pink spandex that revealed both legs in near entirety? That was a fair bit different.
She stepped out of the chamber and glanced around. Despite her body now having superheroic proportions, you could see her movements were at a disjunction with her form: she still moved as though she were her old self. Especially when she spotted you off to the side, took a step towards you and tripped on a cable.
You jumped forward to try to catch her, but you were standing too far back. She gracelessly landed face down, arms barely halting her fall before she bashed in her beautiful face. She glanced up at you and in just a single sentence completely convinced you she was still your girl, "Uhh... Little help?"
You pulled her back up to her feet with but a modicum of strain - her larger stature and altered physique had made her a little heavier than before, but it seemed like a healthy weight. The next thing you noticed was that it was weird to look up to meet her eyes.
"You really like pink that much, huh? I'm still learning new things about you every day."
She blushed, not quite reaching the same level of pink as her skintight outfit, but getting close. "Well, it kinda came with the super I choose. Don't you recognize her? Er.. me, I guess?"
