Donna was having fun using some of the presets but had a goal in mind. She always had a thing for the bad-ish boy who bucked the rules but was sensitive inside. Her brother, who had always been careful to never bring his masculinity/sexuality into question was always way too concerned with being normal and fitting in..
This was the Chronivac 4.6 which had some nifty new features, including mental/physical overlays which used an advanced algorithm to select the key features to overwrite and other features to simply push towards a goal. The model previewer had been reincorporated, releasing the Chronivac 4 without it had been a huge mistake.
Donna had started with her brothers profile but has been playing with the numerous preset overlays. Donna found that overlaying a construction worker and then an underwear model physique was about the same as having found a make sexy button. Sadly she could still clearly identify her brothers face, so although handsome, there was nothing beyond acknowledging that others would probably find him attractive. Though it was awkward that the model was naked.
She added the "starving artist" overlay to him mentally, and was overjoyed to see that tattoos appeared on his model. Alex peaked over Donna's shoulder and chuckled, "Ill never look like that, and I'd never get a tattoo."
Donna rolled her eyes, "This is a game, you're supposed to make your character something better than yourself. I'm just trying to trigger it's mean intent, no harm in me enjoying the character creation piece."
It was Alex's turn to roll his eyes, he has seen her spend hours making a single Sim person and this program seemed significantly more in depth. Alex went to the living room to play a video game on his console.
Donna did indeed spend another hour or so tweaking the settings. After she used the construction worker overlay, she noticed that Alex's age went to late 20's; the underwear model overlay pushed it down to mid 20's and she tweaked it back down to early 20's. She considered putting it down to his real age but remembered that she disconnected it from the internet and she was safe from perverts thinking Alex was a legal adult. if anything about this seems shady she can delete the profile, she reasoned.
Leaving the profile as an adult was more fun for her... jobs were available! Donna concluded by setting Alex's character up as a actor, then she saw boy band vocalist and laughed out loud! She clicked that and clicked save, giddy to move to the game...
The Chronivac popped up a warning, "Subject aware, world and user unaware, are you sure you wish to continue?" Donna flipped back to the internet settings and confirmed that nothing was connected. With a confident smirk that she was right, and this was some prank, she clicked yes, ready to see the malicious content reveal itself...
In the other room Alex was oblivious to the rest of the world, completely absorbed by his game... He slowly aged from 15 to 23, gaining muscle. His clothing style changed, and tattoos and piercings appeared. His room and life changed to match the new reality where he is the older sibling and the rebellious, punk influenced vocalist of a sensationally popular boy band group.
His mind changed, but it didn't overwrite his memory, only his personality. Alex remembers who he was but nobody else does. Everything seems normal but he knows it isn't.
