okay, if you're here, you want a story idea for a vampire diaries/pj crossover. I made this a long time ago (so sorry if it doesn't make any sense)

its a timeline btw

1962: cast into tartarus by Hades

1966: Dies by his own hand, and goes to the other side. Meets Markos (kicks his ass), Qetsiyah (understands her feelings), and also Esther (briefly). He runs into Silena and Beckendorf, whom both had the traveller's gene. (Percy had a werewolf gene, [not activated, {it had to be killing a human; he only killed gods/titans/monsters} but he did have a traveller gene too] which caused him to go to the other side.)

1967-1991: Amara became overwhemled after a giant group of werewolves were massacred (familiar?) and Percy is accidently sent through (along with a few minor werewolves). When he gets out, he meets Hecate,

1991-2012: Percy goes to Britain to spend time with a nephew he found out about (on his mother's side, Hecate knew about Percy being innocent [she actually was on Kronos' side], and decided to help him {later making him protect Bonnie, as she was her great-granddaughter). She stopped his aging process, so he was about 23.

2012: back in America Percy is killed by a demigod accidently (who thought he was a monster in disguise), and is sent back to the other side. There, he meets Kol, Silas, and other dead beings. He befriends Kol, and meets Enzo. He helps Enzo find Silas (who he already met), because Enzo told Percy that he had a chance at getting out. Percy also gets Markos off of Lexi, and kicks her to Bonnie, making her go back to the living. Quickly, Percy touches Bonnie just before Alaric and Damon come.

2013: Percy goes to New Orleans, where Kol tells him to go look for Klaus (they become quite close). Klaus then learns of Percy's heritage through compusion [curious as to why Kol sent him} (he didn't activate the werewolf gene yet), and compulses Percy to kill somebody. (who derserved it, because Percy couldn't deal with the guilt of killing an innocent.)

Klaus then feeds Hope's blood (guessing that she was born while Kol was dead-haven't seen the original's yet) to Percy, and turns him into a tribrid like Hope (third demigod, third werewolf, and third vampire.) He is truly imortal because he has vampire blood, and god blood, making him have no mortal blood in him. (the "mortal" blood in him was pure werewolf blood,)

Percy is not sired to Klaus, though he is loyal to him (trusts him because of Kol, and also because he wouldn't abandon Percy {especially since he's so powerful.})

Klaus tells Percy that he knew his grandparents (who were apart of the Labonair co-ruling werewolf family of the Crescent Wolf Clan), who once ran into him as they were trying to find their baby a home because they heard that their clan was being watched by vampires. He tells Percy that they were slaughtered by Katherine Petrova (not directly; vampires were hunting them down, and she {of course} tells them where they are. Percy later finds out that before they died, they gave Sally to a distant cousin who did not activate the curse, and who lived in New York. Percy finds out that the same group of vampires murdered his mother and Paul after he iris messages them before coming to N.O.)

Percy does not care anymore about killing things (he thinks; they don't seem to have a problem with killing him). He shut off his switch, and doesn't want to think about his old friends/family anymore.

2014: At camp half-blood (Annabeth, Luke, Grover, etcetera are immortal. Luke, Annabeth, and Grover have accepted godhood) Gaia is rising, and Apollo is haunted by a dream of Percy in Tartaus, being released by a blinding white figure. Percy then sprouts wings, and flies into the sky. (Im writing this now, and since this was a long time ago, i think that was also apart of the vision, or i was sleepy and just wrote that for shits and giggles)

okay do with it what you must...thanks for reading!
