Aki Kimuri was born the most astonishing human to ever exist, her potential IQ a staggering 500 points. She learned to read at six months, mastered a dozen languages by 9 months, and had read her family's entirely personal library by the time she was one year old. She'd finished all the local libraries by the time she was 3. At four she attended one day of public school before being passed up through all the grades in a week. Soon she was passing college courses in an afternoon, racking up every degree she thought might be useful.
At five years old she tampered with her own genome, ensuring her future majesty by setting her height to towering levels and completely removing any miostatin limits on her future muscle mass. She worked out hard, far harder than anyone else could, shattering records for her age group and soon for all time. The work paid off and at ten years old she shamed the entries to the world's stronman competitions by lifting more weight than they could hope to move up over her head with one arm. As a teenager she had more strength in her arm than any thirty men and had completely mastered over a hundred martial arts just to have something to do.
Grown into her adult body at 15 years old she tinkered with her body again knowing it was her destiny to be unstoppable. Her biceps could already crush stone but she wanted ever more power. She funded her lab and research and in a matter of months realized how to speed human enhancement and augmentation by centuries.
Her lab assistants had little purpose but to bear witness to her raw superior grandness, for she moved so fast she seemed a blur unless she was working to keep herself easy to see by mere mortals. She built a machine that would encase her and saturate her body with the chemicals and materials to enhance her to a level like a god and decided it'd be her sweet sixteenth birthday present to herself.
All 7'11" of the powerful young woman entered the machine and was encased in metal before being subjected to chemical baths and bursts of radiation that would melt a less supreme individual. She was so delighted by the vast swell of power she could feel tingle in every single cell of her being she couldn't wait for the machine to open.
She tore open the pod, made of a metal she herself invented stronger than any steel, diamond, or titanium and crumpled it up in her hands like so much tinfoil.
"It's time for the weapons test then!"
They hesitated but not for long, wheeling in a powerful minigun normally mounted on the A-1 ground support aircraft and locked it on her. The weapon cut loose with a deafening constant roar as it launched an impossible number of bullets at impossible speed only to have them all shatter into powder as they struck Aki. She laughed, it wasn't anything much different than a warm shower to her.
She flexed her arm, watching her peerless bicep peak and tear her shirt, another specially made thing for her and more durable than body armor, apart with an effortless motion.
She decided to test her speed and ran nearly a mile in little over a second. Unfortunately the terrible disruption of her passing shattered windows, unleashed a terrible sonic boom and might have injured or killed everyone in her lab. Oh well, she just got excited and careless in the face of her new power.
"You know what world? I think I'm going to visit the president and talk about lowering the minimum age."
