Jeff had seen greasers all the time on TV. They had always looked so cool, riding around and looking like total badasses. "Wouldn't it be awesome to be a part of that?" Jeff asked himself. Quickly, he selected the "50s greaser clothes" option and hit enter. He then stepped away from the computer and moved towards the full-length mirror in his room so he could get a full view of the changes to come.
Before anything about him changed, though, his surroundings shifted first. All of the more modern elements of his room melted away. All the posters, trophies, and books disappeared off the walls and shelves, and all the furniture in his room morphed into a style more suited for the 50s. The now-blank walls were quickly filled with posters and pictures of motorcycles and pin-up girls.
"Sweet, this is already looking great," Jeff said to himself, when all of a sudden he started feeling funny all over. He looked back into the mirror just in time to see all of his modern clothes vanish. He was left stark naked in the middle of his room, which was convenient as it gave him full view of all the changes happening to his body. Jeff felt his spine crack as he started to grow upwards, now a respectable and intimidating 6'2", and just as quickly his entire body pumped up with muscle from years of exercise. Jeff's chest swelled forward as his stomach pulled in to a god-like eight pack, while his shoulders expanded outward, giving him the presence needed to control a room. His biceps, triceps, thighs, and calves all shaped themselves to perfection, and his ass swelled out into two mounds of spherical muscular perfection. Jeff admired his body up and down before noticing that his face had also changed! He now had an amazing square jaw and all the features of a classic all-American hottie, like James Dean.
"Holy shit, this is amazing! I'm fucking hot!" Jeff exclaimed, and then clothes started appearing on him. First a pair of briefs formed, barely containing his now giant package, and on top of that a pair of classic blue jeans appeared, rolled at the cuffs. A white t-shirt appeared over his giant torso, and Jeff tucked it into his jeans, starting to assemble his greaser look. white socks appeared on his feet, followed quickly followed by a pair of Converse hi-tops. Just then the centerpiece of the entire look, a beautiful vintage leather jacket, came into existence and wrapped itself around Jeff. Jeff grinned at his new look in the mirror as a pair of dog tags appeared around his neck and his right ear gained a stud, heightening his rebellious look.
Jeff's greaser transformation was topped of by his hair turning jet black and slicking itself back, shooting up high and proud in the front in a glorious pompadour, as worn by any respectable greaser. "Heyyy, this is what I'm talking about man!" Jeff flashed a devilish grin as he started saying greaser slang, displaying the new mental transformation Jeff had undergone. No longer was he an insecure teenager. No, now Jeff knew he was hot shit. He stood up tall, pushing his chest outward with an air of newfound confidence. In Jeff's eyes, this town was his. He could have any girl he wanted (or any guy, if he was being realistic here), and anyone else would be too scared to stand up to him. Jeff was now the guy to be, the ultimate enviable teen rebel with the body to match.
As for the Chronivac, it had reformed itself into a pocket edition, about the size of a smartphone and stylistically representing the 50s to blend in to his new surroundings. The new Chronivac would allow Jeff to switch back to old self at any time or, more likely, give him the opportunity to shake things up in his current setting.
"Alright, lets see if we can't get into some trouble," Jeff said to himself as he pocketed the knew Chronivac. He pulled a cigarette out of his jacket and put it in his mouth, lighting it as he walked out the door and towards his new motorcycle, intent on driving in to town to see who he could find.
