Marvel Story ideas/ mostly Tony Stark story ideas [Prompts]

Assassin's creed spoilers, mostly the Ezio games but also some of the others.

So Tony died. Snapped Thanos and his army away. He figured that was the end of it...oh if only he knew what was in store for him.

He doesn't remember being born again which is a blessing. However he finds he is a child again...but in the wrong time period.

Renaissance Italy, Bastard son of lady named Christina (or whomever you want as long as its set before Sofia if you get what i mean). His new mother told him his father's name was Ezio but his whole family was murdered while the guy in charge was away. While it sucks that he'll never get to know this part of his family it doesn't phase him much, he never knew them though their fate is definitely a tragedy.

To make it even stranger, the world will sometimes turn grey as different things (or people) will turn blue, red, or gold. He has no idea what it is but has already figured out what color means what.

His grandfather hates him, seeing him as a stain on the family, which he shrugs off. He already dealt with Howard so this isn't too different. Unfortunately his mother becomes ill and passes away due to the idiotic medical practice of this age. He barely has time to have clothes and a little money packed before he's kicked out. He is just barely 10

Tony has made friends with the various blacksmiths of the city so he has a job ready for him when he is old enough to work the forge. He makes various designs for various things and is allowed to come with one of the blacksmiths to a different city and show off the designs.

Tony stays active and keeps his fighting moves in tiptop shape by sparing with those who are willing.

Tony is perhaps 13 when he meets Leonardo da Vinci by accident. He was running late and was literally running with some of his designs in his arms when Leonardo stepped in front of him. Leonardo helped him pick up his fallen designs and was excited to ask about them until he saw Tony's face. Tony didn't stay, he quickly thanked him for the help and ran.

It was a while after that Tony began to see people in white hoods hanging around.
Then Leonardo stop by to talk...more so when he finds out Tony's the one who makes the designs.
Tony keeps getting freaked out by the white hooded people because they show up damn near everywhere.

He gets used to Leonardo showing up that he answers his questions when they delve into more personal matters such as his family, life, and dreams of the future.

Tony has days of melancholy.
He misses his family.
Pepper, Morgan, Happy, Rhody, Jarvis, dumme, U, Peter...he misses them all.

Leonardo has no idea how Antonio (I said call me Tony) is so knowledgeable but is awed by the brilliance.

Then Tony makes a new friend, kid his age named Desmond who knows future slang. You bet your ass Tony pounced on that fact.

Desmond has a vague idea on how he got reborn but it's only glimpses of a dark space and a gold tree looking thing.

What they both know is that they both died and was reborn here.

Leonardo's brain fries and has to reboot when he see's Desmond for the first time.

Finally the white hooded person stops stalking and actually talks to him...well him and Desmond.

Turns out Ezio survived...and is having a crisis over having not one but two sons.

Well...he's doing better than Howard, and better than William according to Desmond.

Desmond's got more knowledgeable about what'll happen than Tony does and gives Ezio a story about seeing the future and needing to change it. Tony, and Leonardo once he's brought on board, bulldoze through a few hundred years worth of science.

Ezio wants to be a good father and he is.
Claudia is badass aunt who recognizes that both boy's need all the love they can get.
Mama Maria's recovery is even better and she does her best to love her new boy's.

Tony and Desmond are not used to all the love. Desmond less so than Tony.

Take this wherever you want, I'm not even sure where I was going with it.
This is basically a fix it fic
