Kasey was once a happy little girl until her parents were killed by HYDRA and she was taken with them.A fews later she escapes then makes her way to an orphange months later six people come looking to adopt a girl.

Perseus Jackson always hid who she was, masquerading as a man to protect not only herself but her mother as well. But now, years after both wars, Percy was a SHIELD agent through and through, deep connections forged together with some of the highest ranking agents there. As threats appear on the horizon, follow Percy as she becomes the Avenger's glorified babysitter, dealing with a whole slew of characters. (Perseus is a girl and Pietro is alive)

Percy Jackson, a nine year old Shield Agent, just saw his Aunt's boyfriend/partner get turned into a mindless minion. Now he is willing to do anything to get him back. Even if it means pairing up with a stuck up billionaire, an old man, a rage monster, and a god. Besides he's got some powers they don't know about to keep them in line.

Steve Rogers thought in that night 14 years ago he had lost his loving wife and baby daughter. But the truth is he only lost his wife. His daughter is out there and no one knows it.

*I'm currently rewriting this fic so if you want to read that one, i strongly encourage you to do so* Perseus Jackson. Daughter of Poseidon. Betrayed. Everyone except three of her closest friends leaves her for her half brother. And surprisingly her uncles offer her something priceless. A new life. Disclaimer: Uncle Rick owns HoO and PJO characters and settings. I own the plot. Highest Ranking in Fanfiction #928

So I messed up the tale of the big three then re-wrote PJO some what so that Percy is a girl(fem!percy=Seph). I didn't actually take the time to re write the whole ten books, in fact I wrote the majority of this before the Blood of Olympus even came out(still haven't read it)on a different account. So, Sally died in a fire while Seph was a baby, prayed to Hestia to save Seph and Hestia obliged. Hestia also gave Seph her blessing then asked Pepper Potts to adopt Seph because Pepper couldn't conceive. Also Pepper and Tony got married when they were like 21. So Seph is the adopted daughter of Pepper and Tony Stark, but they love her all the same. All that shit happens, I wrote my own take on the end of the final battle against Gaea and even changed the original story of the Big Three. So, yeah, please read

Peter Parker is definitely NOT your ordinary high schooler. And whatever his classmates thought about his internship, they clearly didn't think he was actually telling the truth. Tony Stark and Peter Parker father/son relationship fic. (Set after Civil War and Spiderman: Homecoming) Not Infinity War or Endgame (or any marvel movie after) compliant

This is my first time writing a crossover so don't judge me if it starts out weird. Percy is 7 and is on the way to Montauk with his mom and dad when it all starts. There will be mutants and all that marvel jazz, maybe even some Uncle Rick cliffhangers. No gods in this story. Uncle Rick owns Percy Jackson. Marvel owns The Avengers. Smart!Percy

After a traumatic experience at age 6, Peter Parker hasn't spoken a word. Most blame it on the fact that he witnessed his Uncle die in a horrible fire, this is only partly true. Now, almost 10 years later Peter is given the chance to finally speak, but will he take it? Or is the fear of his Aunt to much for him to take that chance? Either way, Tony Stark can tell something's not quite right about the "kind hearted" May Parker. (Don't get me wrong I love Aunt May! But I always wondered what if we put a little darkness in the character? That's where this AU was born. Peter's life as Spider-Man wasn't easy before and now with a manipulative and abusive guardian, things only get more complicated but he's still determined to listen to his uncles words: "With great power comes great responsibility) [Book 1 of The Broken Nor Series] [Book 2: Octo Callidus Debitum]

What if actually the aliens in the battle of New York is just a facade? What if Loki is actually nice? He just controlled during the attack. Well, if the Avengers can't see that, the demigods certainly would. Well, this is Percy jackson and Avenger crossover.
