Summary
"The one with the power to destroy the dark lord approaches, born of iron and light as the seven months dies, born beyond the reach of the magical world yet bound to it by fate, the child shall be taken from the hands of the muggles and raised among our own, to parents who have thrice defied the Dark Lord shall he be given, and the Dark Lord shall mark him as his equal but one must strike down the other as neither can live while the other survives, One shall rise to save the entire world or cast it into endless flame.”

Summary
Peter always knew he was the odd one out in his family. It wasn't like he didn't try, he did try to be apart of the family just when he was younger and it never worked. He was never able to connect with anyone, at least not the way Harley connected with their dad, or the way Morgan had everyone wrapped around her little finger since the day she was born.
Peter was just there, in a way he believed that he wasn't important, not to his family anyway. That was what he always believed, at least before he got his powers and became the one and only Spider-man.
Maybe there was a reason why he was always the odd one out after all.

Summary
Harley Stark is a man. The man. Tony Stark’s son.
Except he’s fifteen, and most of his life he’s been orbiting just out of reach — raised by nannies, shadowed by security, managed by his dad’s terrifying assistant. Hidden away, but never shielded: every disaster, every scandal, every headline still hit him, and the explanations never came.
Now, after yet another brush with death, Tony suddenly wants him close. Which means leaving his school, his friends, and the one place where nobody cared he was the Tony Stark’s kid… to live with the man he barely knows anymore.
Between paparazzi, grounding, new friends, and fights he shouldn’t be picking, Harley is stuck in the messy middle ground between wanting to belong and being terrified he never will.
This is a story of awkward breakfasts, slammed doors, counted drinks, and the fragile hope that maybe — just maybe — this time Tony Stark really means it. -

Summary
“You put Peter Parker in our group project? What are you, insane?” Harley hissed, his expressive blue eyes bugging out of his head.
“You guys were the only group of three and Peter wasn’t paired with anyone.” Mr. Wilson shrugged.
“Yeah,” Harley emphasized in an obvious tone. “For good reason, too!”
The teacher smiled widely, his grin all too fake for Harley’s liking. “Great! Glad we got that sorted. Now, if there’s nothing else, I’ll go ahead and eat my lunch without being bothered by another student.”
Mr. Wilson popped open a bag of chips and caught one in his mouth, the crunching noises making Harley’s eye twitch.
The teen took a breath and hardened his gaze.
“So you’re just going to ignore the fact that he’s a murderer?”

Summary
For the next few years, Peter became his dad’s shadow.
They spent everyday together, tinkering in the lab, laughing through disastrous attempts at cooking that left the kitchen in chaos, or curling up for movie nights that inevitably ended with Peter falling asleep halfway through.
It only got better when his dad helped form the Avengers. They had all moved into Avengers Tower in New York, and while it was quite different from his life in Malibu, Peter didn’t mind. He loved it.
He’d have breakfast early with Nat, Bucky and Steve. He’d get spy lessons from Clint (which mostly involved crawling around in the vent and shooting people with nerf guns). And he’d even sometimes get science lessons from Dr Bruce Banner himself.
Life was great. Perfect even.
Until Harley showed up.

Summary
Bruce watched the leaves fall outside the window, careful not to make a sound; he felt scared and confused, but he's adaptable, he is used to this, but he can't handle what he remembers. This isn't his body, his is broken and scarred, not delicate and soft, but most of all, he isn't pregnant, not one bit. But here he is and married to a man he once called his best friend. How did this monster version of himself marry his best friend, have children, and keep them? Can he even fix this?
----
Aka Bruce wakes up in an alternate world where men can have children, and apparently, they have ears, tails that can transform! But most of all, the body of the Bruce he has now taken over was a man worse than his own made-up Brucie persona because he was a spoiled, merciless brat and unforgiving asshole. Now he has to deal with the love he has for his best friend being a reality, with some steps skipped, being pregnant, and having many children. Bruce needed a nap.

The identity that kept him safe for years is now the one thing he has to hide. With a family that watches his every move, how long can he keep the mask on?

Summary
What if Tony Stark was born in 1940.
What if Tony Stark ran away at 16 to join Hydra as a "fuck you" to his abusive father.
What if Tony Stark turned into the most powerful man in the multiverse.Or
"Just when I thought you couldn't be a bigger failure." Howard bites out, anger pouring out of every paw.
He has to get out of here. He always knew he if he was to present as an omega his father would turn him into a bargaining chip and see him as nothing for than a disappointment and a whore.
He had to think of a plan and fast. Yes, he'd miss his mother, but there is probably no fate worse than being the omega son of Howard Stark.

Summary
Pepper and Tony Stark’s biological kids, Morgan, Peter, and Harley, were kidnapped eight years ago. While Harley and Morgan made it home, Peter was lost all that time, believing his parents had abandoned him on purpose. When they finally find him, he’s scared, malnourished, and struggles to understand what it means to be part of a real family.
And then there’s Spider-Man. Peter’s doing everything he can to keep his identity a secret, but how long can that last? Will they still let him go out if they find out? Will he ever figure out how to fit into a family that genuinely cares about him? Reuniting is one thing, but rebuilding what was lost? That’s something none of them are prepared for. Keeping his double life hidden was hard enough before, now, with a family that’s protective and watching his every move, it feels impossible.
His family has their own struggles, the guilt Tony and Pepper feel knowing what Peter went through alone, the grief of missing his childhood, and Harley’s pain of losing his twin for years, never knowing if he’d get him back.
(I personally can't handle long fics, but this one is angsty every chapter, so it's one even I would be able to handle. Also I suck at summaries, sorry.)
