The Umbrella Academy and PJO/HOO crossover Sally Jackson was one of the 43 women that give birth on October 1st, 1989. The unusual thing about all this births was that neither one of the them was pregnant went the day first began Poseidon, Earthshaker, Stormbringer, Father of Horses, God of the Seas, fell in love with the one and only Sally Jackson and he was there when it all happened. He knew he needed to leave, so, to prove his love, he blessed the child. Said child was a little girl that her mother had named Persia. Sir Reginald Hargreeves was curious about the events of that day so he adopted all the children he could get. He got 7 of them Little Persia was supposed to be one of them, but being the last thing Sally had of Poseidon, she made a deal with the millionaire. ~~~~~~~~~~~~~~~~ Note #1:This is just based of the show, I haven't read the comics Note #2: English is not my first language Note #3: I don't own, neither The Umbrella Academy or the Camp Half-blood Chronicles (I'm not including TOA 'cause I haven't finished The Tower of Nero) Note #3: Fem. Percy (I've been obsessed with that too)

With Sally and Paul missing, Percy learns that he has a mortal uncle. Tony Stark was not expecting to find that he had a nephew; nor that said nephew was a terrorist, according to SHIELD. What side is he to choose, his work- with the Avengers(with SHIELD), or this boy- his chance at having a family? Likewise, the Avengers are also surprised. Percy is keeping secrets, and they don't know if they can trust him. Is he dangerous? Or could he become part of their ragtag family? Perhaps both? How will Percy handle all the things that are getting thrown at him? Will he manage to stay himself through it all? ~~~~~~~~~~~~~~~~ Current word count is 122,856(as of chapter 55) ~~~~~~~~~~~~~~~~ Most Impressive Ranking: #1 in percyjackson September 28th, 2019 #1 in thor June 5th, 2019 #1 in avengers June 9th, 2019 #1 in crossover August 10th, 2019 #1 in nicodiangelo August 24th, 2019 ~~~~~excerpts~~~~~ "Brother, what if the other gods learn of this?" "They will fear him. They will fear him in a way that only cowards can fear someone weaker than them." ~~~~~~~~~~~~~~~~~~~~ "Okay. So, what are you gonna do?" "You will just have to wait and see, little cousin." She says. "You are really tall for a girl, but I'm still taller." I reply. "I'm older." "You were a tree!" "Still older." "You stopped aging just before you turned 16. I'm seventeen." I argue. "And I haven't had my years messed with." "If I hadn't had my years messed with, I'd be twenty-one." She smirks. "If we go by dates, then Nico is the oldest." I comment. She stops walking for a minute. "No. No, he's little. He's little cousin." "Then so are you." I smirk. She glares at me. "Agree to disagree, Kelp head. C'mon, we've got stuff to do." ~~~~~~~~~~~~~~~~~~~~ I do not own the characters, they belong to Marvel and Rick Riordan. Cover is made by @ShipCanons However, the plot this fanfic takes is TOTALLY mine and I'm proud. Chapters average at just over 2,000 words each.

He stood on the balcony, watching the city below. His trained eyes flickered from one event to the next; the angry cabbie shouting for the traffic to move; the dog walking their owner along the streets; the father trying to keep his children in arm's reach. He sighed, rubbing his hands on his arms. He saw no real threats, no monsters in the shadows and no waiting traps. It was normal. If only he could be too. I do not own anything from Percy Jackson or the Avengers. TRIGGER WARNINGS

No, the seven and anybody else is not dead No, they did not betray him And NO Annabeth is NOT evil But other than that this story is about Percy and the avengers meeting This is not going to go well is it?....... Especially when you mix a bunch of memes in here and when Tony decided to steal a puffer fish.
