So I'm about to list a bunch of ideas for Percy Jackson fanfictions you can use that I would love to read. The only thing I ask is if you use any of these ideas, tell me, maybe tag me in the book if you want, and please send me the link to your story or tell me about it in the comments. You can also use any of these as inspiration for your stories. And yes, I know some of these are weird, but I'm weird so what do you expect? This also contains spoilers, just a warning.
-Personality switch. Basically the Seven or any other characters switch personalities. For example, if Percy and Annabeth switched personalities, Percy would act like Annabeth and Annabeth would act like Percy. Does that make sense? I know BoopTheSnoop_ has a book kind of like this, his god swap book which I love, but this would be a little bit different.
-Jason breaks up with Piper, but instead of taking it well like in the books, she becomes angry and uses her powers on him. She becomes corrupted and kind of goes on a rage using her powers on a ton of other demigods, gods, or characters. Also, it might not be exactly like in the books because I forgot if Piper was the one to break up with Jason or not.
-Hypnosis. That's it. Anything with hypnosis. Or love potions. Or anything like that.
-Percy and Annabeth, or any characters, are sent to an alternate universe where everyone acts the opposite. Then the version of Percy and Annabeth in the alternate universe are sent to the real Percy and Annabeth's world and they take their place and pretend to be the real Percy and Annabeth. And like I said, they act the opposite so everyone is confused. Meanwhile, the real Percy and Annabeth have to escape the alternate universe while also dealing with everyone acting the opposite of themselves in their own world. Does that make sense?
-I really like Drew Tanaka, so anything where she uses her powers to change the Seven or any other demigods. As in personality-wise and whatever
That's really all I can think of at the moment. And like I said, it doesn't have to be exactly like what I said, you can use these just as inspiration. Just make sure to tell me if you do any of these or use these ideas! I'll probably make a part 2.
