The gods and Demigods (except Nico and Hades and Blackjack/Grover) think Percy Jackson is dead. Killed himself when Annabeth died. He lived in the Underworld for a small amount of time. He visits the Graveyard to visit his other friends too. He is still scared to death of Tartarus but has accepted the Underworld. What would happen if Tartarus comes back? Percy and The Avengers team up to defeat the Primoral and send him back to Tartarus. (I'm not good with Prolongs and stuff.

In this story, the Harry Potter prophecy is really about both Harry and Percy. Same old, same old.... Harry and Percy are twins, sons of Lily Evans and Poseidon. Lily and James got married when she realized she was pregnant. They both live with their muggle (and mortal) family, the Dursleys. The twins had to depend on each other (and only each other) their entire lives to survive. Everything changes suddenly as they started receiving mysterious letters... (Mainly follows the plot of The Sorcerer's/Philosopher's Stone, mostly from Harry's perspective. (3rd person POV though.)) I'm going to put this on ao3 as well at some point. Past chapters are being continually edited when I have the time to help get rid of younger me's cringe, but nothing too big will be changed without a notification about it.

Perseus Potter was three years old when their house was attacked. His mother handed him his baby brother and told him to always protect Harry. So he did. He even went so far as to jump in front of the killing curse. Dumbledore told him that Harry was to be the chosen one and to always protect him. Strange things begin to happen when the older Potter begins to attend Hogwarts. Missing students, strange creatures, secretive teachers, and hidden parentage. It is sure to be an eventful year.

After the giant war, Percy wants to get away from the mythological life, and so do Sally and Paul. So what to they do? They move to Mako, Australia.

Percy is well known in camp half- blood but he may have lied about his past. His brother is the famous Harry Potter and every year he goes to hog warts. ( warning- Harry will not be the hero Percy will)
