The moment he noticed several differences from before. For starters his hands, feet, and knees no longer hurt, and his skin was thick, smooth, and covered in slime. Meanwhile his granddaughter in front of him squeeled in excitement and ran out of the room screaming "grandpas out!".
He stepped down from the pod and began examining his body, his body was young about mid to late twenties, a level of muscle and fat that one would see from someone with daily moderate exercise and a balanced diet. He was very much at his prime age wise but otherwise average for his prime. Moments later his eldest son and grandson rush into the room finding him in his prime once more.
"My god... I haven't seen you like this since I was in pull ups..." The son said.
"Yeah... Get me a set of clothes, I need a shower." He said as he flicked slime off his hand.
A while later after a nice long shower he steps out of the bathroom drying his hair and donning a set of sleek white minimalist clothes prime for learning what he's capable of now. As he arrive at the courtyard where his family is he gets another notification on his nanite replacement of his old neuralink. He unlocks the door for the young man from four months prior, he figured the pod was rigged to notify him the moment he woke up.
"Hah... I flew here as fast as I could!"
"I know."
"So how are you feeling?"
"Energized, weightless, painless." He answered as he bounced up and down as if on a trampoline.
"Well that's good, have you tested out the transmog system?"
"There's a transmog system!?"
"Yes just imagine what you want to look like and the nanites will give a response asking for confirmation, just confirm and they'll do the rest." He explained.
"Hmm, I'm old so I should stand out as a way to displaying my wisdom."
The next moment his hair begins paling starting at the roots and spreading to the tips and soon his entire head of hair is snow white.
"What color is better for wisdom than white?"
"Oh that pairs well with your baby blue eyes!"
"Yeah I saw it in an anime once."
"Well what are you going to test next?" The young man asked.
"Hey Silas come here." Gideon said urging his eldest grandson over.
"Yes grandfather?"
"You know how to fight right?"
"Yeah why?"
"Let's spar."
"Are you sure? You just woke up."
"Yeah I got an advantage."
"Alright whenever you're ready-" He barely managed to finish his sentence before being forced to dodge an air piercing punch.
He returned the punch with one of his own which was countered by a kick to the sternum. Silas was sent back a bit by the kick and was also unbalanced from it but rebound back to his feet however by the time he looked back up Gideon had already closed the gap with a flying knee. Silas caught the knee and flung Gideon away by the leg . By the time he'd looked up his grandson and mimicked his own hyper aggressive tactics with a two rotation flying kick so powerful you can hear the swishing of air before it lands.
Gideon managed to get his arms up just before it landed thudding into his forearm with so much force it almost knocked him off his feet or snapped his forearm. After that both of them calm down and put down the combat stances.
"Damn what are they teaching kids these days?" He exclaimed as he looked at the deep purple and red bruise spreading across most of his forearm.
"Sorry Grandfather, I didn't mean to hurt you!" Silas exclaimed through exhausted breaths.
"Don't worry I'm sure the nanites will heal this in no time."
"Give it a few minutes." The young man said.
"Really that fast?" Silas asked.
"Yeah and that's only the passive healing, he can tell the nanites to focus on healing and they'll speed up the process."
"Damn, nanites are potent huh?" Gideon asked.
"Yeah, however the U.N is going to make us restrict its functions to keep people safe and whatnot which we've already done some of. For example you're incapable of free control of the nanites since you could use them for invisible crimes including murder and stalking." The young man explained.
"Oh that's reasonable." Gideon said.
"Well I have to go, enjoy your newfound youth and message me if you have any questions." He said before leaving.
"So what do you plan to do next grandfather?"
"Hmm... I dunno, sports? Hobbies?" I'm not all that different." He said as he left the courtyard.
Later that night he sits in his room watching the news on a TV floating in the air in front of him the area around it dimmed. Right now the U.N is debating the nanites, currently limited nanites exist mostly in the form of one time use medical nanite serums. You inject them and they solve whatever disease, condition, or injury you have however nanites haven't managed to bypass the large heat generation by nanite activity until the breakthrough with the nanites he's using right now.
So my nanites come pre installed with restrictions they knew the United nations would demand, I can't control the nanites outside of my body and even if I could they're restricted from forming shapes like blades and keys, and they're unable to hack even a toaster. One of the bigger restrictions are the restrictions to changes I can make of my own body, I am unable to use the transmogrification to bypass facial recognition or fingerprint scanners. I'm sure they didn't stop there... If they do wanted they could probably stop my heart...
On the news the meeting continues and the owner of the company who invented these nanites, the young man from earlier father stands up to do something. This is when he notices his limp is nowhere to be seen.
I will not be owned.
