Celeste is not your average demigod. With god-like powers, her father Poseidon cursed her to be invisible to every living creature. She follows her brother Percy Jackson around for spare time and is shocked to find her wish come true when her curse is mysteriously lifted.

Adopted from: @Castiel_Is_A_Bee "Tony, meet Perseus Anthony Jackson, your godson." *~*~* Best friends since high school, Tony Stark and Sally Jackson have been through a lot. Take being the only 10-year-olds in the 9th grade as an example. After surviving that, Tony and Sally thought nothing could stop them. Until Tony decided that it was a good idea to get kidnapped in Afghanistan. During that time, not only does Sally worry sick about her best friend, but she also gives birth to her son: Perseus Anthony Jackson, named in honor of her missing (possibly dead) best friend. Once Tony returns home and Sally slaps his smirk off his face, she introduces him to his godson. The duo was inseparable from the first moment they met. Whether it was saving the world or pranking, godfather and godson were always together. But the world couldn't know that, and neither could the Avengers. People couldn't know about Tony Stark's little family. Percy and Sally would be out in too much danger. And I think they got their hands full with the Olympians. But what happens when it's Percy's turn to disappear? (Thanks a lot Hera). The Avengers have fought aliens, they can handle gods, right? (I mean they live with one) DISCLAIMER: I DO NOT own Percy Jackson or Marvel. All characters belong to Rick Riordan and Marvel. The original story line belongs to @Castiel_Is_A_Bee. Cover made by @Fandom-Princess7875. Disclaimer #2: I started writing this in middle school so the first parts might be pretty cringe (slight OOC warning). But trust me, the grammar is good, and yes it's separated into paragraphs.

Percy is forced to live with his uncle, Tony Stark, when his mother goes on vacation. Percy does a good job of hiding his secret from the Avengers. That is, until the camp comes under attack and Nico along with his twin sister and Annabeth drop in unexpectedly. Tony never kept in contact much with any of his family, so he never expected a call from his cousin Sally. He was about to reject his cousin's request of him babysitting his nephew, but everyone else insisted that he accept Sally's request because they were curious to meet what ever family Tony had. So Tony agreed to take Percy in. As time goes on, he thinks he bit off more than he could chew when the Avengers are throne into the world of demigods and Greek gods. Cronus has come back for his revenge against the Demi-gods. His revival forces everyone in camp Half-Blood to go into hiding. He plans on destroying those that oppose him and to take over the earth. _______________________ I own nothing but my OC (aka Nico's twin)

Percy comes back to camp to find himself to be the last Demigod in the world. The gods decide to force godhood and immortality onto him before sending him back to his mother, only to find her dead too. However, Sally Jackson has a brother he had never met before: Bruce Banner. I'm pretty bad at summaries and I don't want to spoil anything else, so just read the book to find out! : ) Disclaimer: I don't own anything. Not even the cover, I found that online. Also! Suicide warnings involved in this book. Don't read if sensitive to such things. Note: Incomplete story in the process of being rewritten! Will likely be reposted on AO3 once finished. Sorry!

The gods have Percy and Nico help the world that is unknown to demigods. The Wizarding World. Percy is changed into his fifteen year old self so he can fit in, and him and Nico are sent to help stop the war against Voldemort before it even starts. (This takes place after the Giant War and during Harry Potter's fourth year at Hogwarts. You really shouldn't read this if you don't like Percico.) *Art by Viria and cover made on Moldiv app*

After being betrayed and hurt, Olympus' savior disappeared but was soon found...by the Avengers. Percy accepted the offer of joining and is now one of the Avengers. New enemies will rise, Arguments will appear and old freinds wait for Percy's forgiveness, will Percy forgive them? As he thinks about that, he with his best freind fight with their new found freinds and enjoy their life, the Avenger life.

This is what I think would happen if Percy said no to going with Chaos. Yes this is a Percy Jackson/Avengers/Harry Potter crossover. After Heros of Olympus (book), Deathly Hallows (book), and Age of Ultron (movie).

Betrayed and Cheated Percy Jackson runs away only to find his real father is chaos. He disappears for a while before returning to defend the place he once called home. While he is back a certain silver eyed godess catches his eye and then his heart. COMMENT VOTE AND FOLLOW

After Gaea and Voldemort's defeat, various demigods enrol at Hogwarts. They befriend Harry Potter, fail homework assignments, and train the wizards to defeat Voldemort (who's somehow back from the dead) and his army of Greek monsters. But first...a bit of death gets in the way... ➵ cover by @ChloeCGS ➵ pjo / hp crossover

Percy and his gang were sent by Chiron, their camp director to Hogwarts, a wizarding school. The Oracle of Delphi predicted that the wizards are in great danger. So their parents, the gods and goddesses of Mount Olympus, sent their children to create a bond between the two species. Harry Potter the boy who defeated Voldemort, believes that wizards are the only people with powers. Even though he already defeated the greatest wizard of all time, dementors are still stirring, attacks on muggles and wizards alike are becoming frequent. Is it a good decision on the part of the gods, for making their paths cross?
