What about an alternative universe where SIM!Tony and Tony share the same body like two souls trapped in a jar together ? SIM!Tony knew about Tony but Tony doesn’t know his other persona, they fell for the same certain spider but one wanted to kill him while the other wanted to beg for his love.
SIM!Tony x Muse!Peter x Tony Stark
This is post NWH where Tony is alive but half of his soul is damaged which leads to SIM!Tony (that defeated by Spider Man) got pulled from another universe to fill the gap in Tony’s soul.
Another note is OG avengers not dead in this fic.
Sometimes there was a hole in Tony’ memories but he pretended it was fine until he exhausted himself trying to catch up with Rhodey’ unknown discussion, Pepper’s concerns about the tabloids saying he's coming back to his old self, and Happy’s distant face.
It suffocated him so much.
Sometimes Tony found himself dozing mid day, it felt weird seeing his body move on his own, it was like watching a movie in a third person view where he was trapped between consciousness and unconsciousness.
Other times Tony just woke up in an alley where he definitely didn't know before, his body ached, lips busted, his mind all messed up and when his body went down from the adrenaline, he felt it instantly, the fatigue and the dizziness washed over him waves by waves. He almost collapsed on the ground seizing.
It was strange, to the point Tony felt like he's becoming insane.
From FRIDAY called him Superior to the new version of his arc reactor to a new substance called Extremis that heavily violated the ethical principles.
But one thing that stood out the most is…the boy.
The first time Tony saw him was not - person to person, but via a painting that hung on his bedroom (he didn't remember when he placed it there). He admitted it was a nice painting, the boy(again he didn't even know whether that person is a boy or not but somehow his mind said they're a boy) no older than 20, he stood there naked with this back facing the audience, white cloth draped over his lower body half hiding his smooth legs and covered up the hidden forbidden fruit, but what caught Tony's eyes the most was the huge spider tattoo on his back.
It was mesmerizing, something deep in his guts arose when he saw them.
From that moment on, everywhere he went, he saw the boy and everytime the spider tattoo made his brain go haywire.
In his labs, in his office, on his bed.
The draft for a spider emblemed suit ? A hand drawn sketch of the boy and more complicated equations for some substance. (That's weird, because he swears he never seen this before and further what's a sticky substance is going to benefit him)
One time, he even saw the boy laid beside him when he woke up in the middle of the night due to unrecognizable nightmares. The boy still got his back facing him, the moonlight peeks over his window draped over the figure, he can see the pretty and delicate shoulder blades, the spine, the bitable nape and-and the curls, my god the curls. He wanted to touch them but he's afraid the boy will disappear.
He didn't know the boy but somehow he can taste him. Yes taste, he felt it in his tongue, the softest on his lips, the sweetness of skin, the copper-like fluid on his palate.
Tony felt hunger. Like he was poisoned.
It finally gets to the point Tony couldn't ignore it no more, these strange things have been going on.
There were numerous reports about a new villain in town, the threat was evaluated to be between normal to Avenger level threat which is pretty concerning considering last time Avenger level threat was Thanos - Tony hates him.
The new villain was suspected to be hell of a genius (Tony didn't want to admit the guy is smart but he earned himself some credits) The villain possessed some kind of super soldier serum but not the same as Bucky or Steve, he also possessed Iron Man copy cat of armor with blue and white - that mother fucker, Tony’s gonna sue the fuck out of him.
Strange enough, the more he got reports from the new villain the more gaping holes in his memories became larger over time. Some days he… even forgot the mission. And the villain got away just in time before the Avengers could do anything like the guy knew what's they're gonna do.
Tony was not sure whether or not he's dreaming, he saw Cap throw his shield to the villain and he missed. God, Caps getting old, Clint is never going to shut up about his ‘ill never miss’ aim assist. In the corner of his eyes he saw Black Widow shouting something but it was completely inaudible, he saw James Buchanan Barnes - yeah the guy he had a hard time to get to an okay terms with, looked at him with sadness in his eyes and Bruce - his science bros, the one who he vented about the stupid villain technology, desperate synthesize something in the labs despite currently in fight with the villain which was not his usual move at all.
Shit. He said that out loud ?
What the actual fuck ?! He saw Clint was aiming at the villain-?! Wait, this is not his suit. This cool and slippery feeling is not his suit at all, this is not how his nanites should be moving- THIS IS NOT NANITES. NOT HIS.
The suit engulfing his body suddenly moved on its own. It flew through NYC, the buildings, the people and its scenery flashed through his mind but he's too caught up with his mind.
He flew across the question written on the wall of a random ass sandwich place.
Spidey ? As in Spider-Man ?
He didn't realize the suit had stopped long ago until his feet touched the floor of his Tower.
He walked forward as if he was hypnotized.
In front of him was the boy…naked in a tube surrounded by water ? No the consistency is too thick to be water and the color ain't right too. Formalin.
Tony felt like vomiting. The boy was preserved like some kind of exhibits animal.
His voice got out as he was pushed back.
“You must be surprised, Tony Stark. I guess everyone will when they see this”
He felt his body move towards a mirror. He still looked the same, no way.
Deadly blue eyes, a maniac grin splattered on his fucking face.
Not Tony, not Tony, not Tony-!
“It was kinda a shame that the only person who recognizes the real you first is dead huh ? Everyone else became suspicious after I intentionally revealed my true self, a little play here and there is enough to fool them all. Hell they even like me, everyone is grateful for a more powerful Tony. Everyone but that pretty boy, he got suspicious before I could even say hello. It was really a shame, he was so sweet looking at me with earnest love in his eyes, only to be crushed when he saw me.”
“That spider in every universe, could never stop causing me trouble. That pretty boy with a god sent ass always gets in my way, it was funny seeing him desperate on his knees trying to rationalize me in order to bring you back. He was so cute…”
His body moved towards the tube this time.
“That I couldn't help but kill him”
“My muse … all pretty for me, for us.”
“Isn't that what you also want ? Stark ? For him to be forever in our grasp.”
I really like SIM!Tony, there's too much I want to write about this guy. He's a red flag but I'm blind.
