Age of Charon by Eneid_Elisor

Summary
Rebirth was not something that he had thought possible. Perhaps, he had had some vague hopes of reincarnation cycles as the more desirable option to afterlife. But being reborn in what he believed to be a fictional universe had only seemed as the premise of stories.
Waking up to a void of nothing, no light, no body, no feeling, and then being thrown into the midst of what had once seemed a mere fantasy— it was too much.
As an A.I., how much could he change? Could he save Tony? Could he save the world without his sacrifice? Or should he not do anything? What if his existence was the butterfly that would destroy the timeline, and with it, the universe?
Was this even a choice? Was he to play the villain? So the timeline could remain intact?
Could he even do that?
"You doing ok, kid?" Tony asked him.
"I'm fine, Tony, really."
No, no, he couldn't.~~~

Summary
AU. Tony Stark is the Top Forensic Scientist at S.H.I.E.L.D. and possibly in the world - if he does say so himself - there’s only one person he’s come up against and can’t beat: international criminal mastermind Loki Laufeyson. He’s gotten close but Loki always has a lackey to throw in front of the blame. He’s completely untouchable and if Loki wasn’t his enemy than Tony would be marvelling at and adoring his genius. But Tony can’t, because he’s a good guy, he has morals and a duty to the public that he’s trying to protect. Loki Laufeyson, however, is equally fascinated and he doesn’t do anything other than what he wants. COMPLETE.

AUs, some truly creative story lines - Jane with Thors Hammer and a freshly defrosted hammer is superb - keeps so much of her character and intellect in the writing. And Steve using Magic, another one where the implications are not as expected. Some of these are so excellent

Summary
Outward appearances can be deceiving, some people know that more than others. If you work for S.H.I.E.L.D you know that all too well. With the Avengers initiative it's common for one to doubt the capabilities of its members by a simple glance. The hammer of almighty Thor proves to be very godlike, the titanium alloy suit of one Ironman struts its many striking features, the shield of the infamous Captain shows to be unlike any other metal, but one member of this team has a more deceptive shell than the others. Bruce Banner is the Hulk, and not many can tell from looking at him.
Dr. Banner returned to the helicarrier before anyone and stayed there longer because of a certain subject he was asked to study, but this subject has an even more effective camouflage than even he. Upon first inspection he thought he was looking at a flower, but he found a beast residing within. Caged, alone, filled with hatred... Does he actually have feelings for this creature? Will this determine his loyalty?

Iron Man Lives Again [Or, Why Team Captain America Didn't Think This Through] by Dont_call_me_Carrie
Fandom: Captain America (Movies), Iron Man (Movies), Marvel Cinematic Universe, The Avengers (Marvel Movies)
23 Aug 2020
Summary
It’s a fundamental constant, that Tony Stark is a billionaire and a genius and philanthropist and we’ve heard this time and time again over the movies. Nobody in canon seems to appreciate just how much of a bullet they dodged, though [
not so much a bullet as a Jericho missile]- that Tony, being Tony, focused on a better, brighter future, and not, you know, world domination. [It would have been so easy, at any point.]But then again, there’s so many times when Tony Stark could have thrown in the towel and made the world a far worse place, long before the good Captain even got defrosted- and even more so after.
[
Even if heroism is as integral as genius is to his character, it's still a fun thought exercise.]
The War is Far From Over Now
— the crack taken seriously AU, feat. Accidental World Domination. Diverges after IM3.
Moments of a Dying World
— a tragedy in which rocks fall, everyone dies, and Thanos is vaguely impressed by the carnage. Diverges after AoU.- Words:
