Marvel : Grey Matter as Illegitimate son of Tony Stark

One of many novel-reading guys traverses to Marvel world with the ability to transform into grey matter.

Yes, that frog alien from Ben 10 that can create any technology as long as they have knowledge.

Let’s see how our MC who is just a college boy with no technical knowledge, will create his business empire when he is just a weak chicken who just entered society and can create mistakes n mistakes because of inexperience how will he create a solid foundation for his business empire and how to save himself and his loved ones from unknown threats.
And what will happen after earth was destroyed by Tiamut or any other Celestial.

Inventions : Baymax, Cyberpunk 2067 luxury cars, Hydrogen engine, 3A games, Movies, Steel robots arena, etc.

Well, although my introductions are not cool, so next time try to write cool intro.

Well, I am only interfering with timeline, so these original timeline and characters are not mine creations. I am just making fanfic MCU by my setting.
Also book cover is not mine so pleeeaase no offense, if he wants to remove it, message me and prove it, okay.
Well intro is a bit long happy time, GUYS.
