Amber decided to change "Convenient" with "Super", thinking it meant that the pullups would make her feel good. Suddenly Amber found herself wearing glasses and her clothing changed into a more professional and mild-mannered white button shirt with a red bowtie, a charcoal gray suit with matching skirt and shoes, and black tights covering her now super powerful pullups.
New memories flooded Amber's mind. About a year ago, she had an internship at the local diaper and pullups factory. She had been helping the chief inventor, Dr. Glenn Starling, with paperwork and various odd jobs. The Doctor had been working on a new kind of pullup, one that would absorb all bodily fluids and odors into itself, never get any bigger and always staying clean. However, there were two problems with the pullup. It converted everything it absorbed into energy that would irradiate into the body of whoever wears it. And it fuses with the person wearing it, covering them from the waist up in the same material as the pullup at the wearers will, and can never be taken off.
One night Amber was on her way to the restroom, because she had to go really badly, when suddenly she heard an explosion from Dr. Starling's office. Amber ran in to save her but was too late, nothing left but the prototype pullups she dedicated herself to. With the fire was spreading to the rest of the facility, Amber grabbed the pullups and try to escape. Some of the fire gets on her pants and she's forced to remove them along with her panties. Amber makes it out the building alive, but trips on a rock that sends her and the pullups sliding down the hill. Amber manages to maneuver herself to slide feet first but is unaware the pullups are directly below her and opened up. By the time she saw them, her legs had went through the hole and the pullups were around her waist. Amber was so shocked that she didn't see a random comstruction poll rapidly approaching and she crashed into it crotch first. Amber lay on her back for a while until a tingling sensation covered her whole body. The impact caused her blatter and bowels to go off and completely fills the pullup. In turn, the pullups absorbed all the waste, fused itself to Amber, and released its stored energy into her. Not only healing Amber, but also granting her superpowers (including super strength, super jumps, energy blast, super healing, and growing to 100ft. tall). Now Amber uses her new abilities to battle evil as, PULLUP GIRL.
Amber sat in her chair completely stuned. Not only was she wearing a permanent pullup, but she was also a superhero as well. What was she gonna do now.
