lol, that sounds like the CEO when younger lol. I'm writing the first of what will be a series of three books which occur when he's already an immensely powerful politician and businessman when the guy's in his 200's (400's if you count being in cryostasis), but I hope to write a prequel to all of them to show how he develops. He is born into a family so wealthy and powerful, the Extuli-Human Empire (the UHR doesn't rise until a few years after the Empire falls) considers them critical to their security as their company is the sole provider of superluminal drives (at the time, only warp drives are possible).
Unfortunately, it's not all unicorns and lolipops for the kid born in the early 3000's to Johnathan and Rachel Tesla. In the first (and last) test of a manned superluminal flight in-atmosphere, Mrs. Tesla gets shredded in a malfunction just over a year after her son is born. Being raised more by robotic butlers and money than parents, the kid becomes a problem. Eventually, Johnathan is assassinated by an anarchist while the son is in his early twenties and leaves the entire inheritance to his son with the condition that he is able to answer satisfactorily a series of questions to a beta-level AI of Johnathan. It takes more than a decade, but their son Nicholas ultimately takes the reigns of the largest company in history. After nearly seventy years of success and wealth, he decides to begin testing on new mechanisms that would allow near-instant transit between two arbitrarily distant points in the universe and the release of a line of sentient robots.
The combination of these leads to what becomes known as the Holocaust, a near-extinction of the human race that also turns the overused idea of robots killing all humans on its head. The Holocaust involves the glassing of Extuliani, the homeworld of the Extuli and the imperial capital, and after a few years of chaos, Nicholas finally stabilizes the core worlds enough to create the United Human Republic which defends the last few dozen remaining systems until a final climactic battle in which Nicholas's ship is destroyed and he throws himself into cryostasis in an attempt to survive until a rescue party comes for him (this is the end of the prequel). Unfortunately, he's not found for two hundred years at which point a group of anthropologists is looking through the wreckage and happen to stumble across him.
He never loses his sarcastic and sardonic nature that he grew up with, making him by far the most entertaining character to write in my book simply because despite the book seeming to center around the soldier, if you also look at the prequel, the entire series centers around him.
