So I absolutely love the idea of a Kane Chronicles/PJO crossover in which somehow Nico accidentally becomes the host of Anubis.
Nico and Anubis are hanging in a graveyard. Anubis is standing behind a mausoleum so when Sadie and Carter find them they are understandably confused. After all, Nico looks very similar to Anubis–so similar, in fact, that with Anubis behind the mausoleum, they thought Nico WAS Anubis.
Anubis moves to introduce them. He calls Nico his friend and goes to pat his shoulder when *something* happens. And suddenly Nico has fallen and Anubis's form vanished. In Nico's eyes instead of pupils there are golden ankhs. He's understandably panicking, and Anubis appears again, trying to comfort him.
Because somehow, when Anubis placed his hand on Nico's shoulder, he took him as a host. So Nico has a god in his head now. And he can see into the Duat.
Just imagine.
Nico fighting like a demon, the faint image of a jackal fighting alongside him. Throwing out Divine Words as he summons shadows and bones. Biting with extra-sharp canines if he's trapped. A wild animal, and in each eye a golden ankh, burning with the fury of the gods.
On the other hand, he works through some stuff
He becomes less shut off from everyone. Less anxious with somebody in his head to reassure him. Anubis is respectful; he backs off when Nico wants to spend some time without the voice in his head, but is always supportive when he's needed.
Nico and Anubis in Tartarus.
It would be hard for Anubis to reach him down there, of course, because though death is universal, monsters are not, and Tartarus is just so very Greek. All Anubis can manage is to lend Nico some strength, which is all that keeps him from dying in the house of Nyx. When he's captured, it is Anubis's power that keeps him alive until the Seven can rescue him– the pomegranate seeds are powerful, but not that powerful.
When Percy and Annabeth fall into Tartarus, Nico can't move. He desperately reaches out to Anubis, allowing him to possess his body, not caring in anyone finds out. They sprint forwards and Anubis casts a Divine Word– Tas, bind, to create a net keeping the two up. But the pull of Tartarus is too strong, and they fall anyway.
Nico beats himself up about it. After all, if he hadn't frozen, hadn't taken the time to decide to let Anubis take the reins, he may have been able to save them. But Anubis gently reminds him that some things are meant to happen, and Nico doesn't blame himself as much, especially once they emerge from the Doors.
Eventually he tells the Seven. He introduces them to Anubis and Brooklyn House. Everyone becomes really great friends. Nico has dinners with the Kanes. He visits Brooklyn House often, occasionally bringing Percy and Annabeth if they want to see Sadie and Carter again. He even brings the rest of the Seven sometimes. Eventually, he starts bringing Will.
Bast kind of dislikes Nico from the beginning, because of his connection to/the fact that he is hosting Anubis, but soon she grows to think of him as another of her kits.
When Hades finds out, he asks Anubis to show himself, so he makes another form and Hades chews him out (how could he be so irresponsible, does he have any idea the danger this holds for Nico, does he even know how to mitigate the damage that their powers combined will cause to Nico's body, etc) but it's clear he's just worried. When they explain they're okay Hades kind of unofficially adopts Anubis, despite them being from separate pantheons. Nico is Prince of the Underworld, and now by extension, Anubis is Prince as well.
Anubis helping Nico accept himself. Nico in my AU is non-binary and it takes him a while to come to terms even longer to accept that he doesn't have to look a certain way just because of his gender or because of his being the child of Hades. Anubis helps him realise that he can wear colours, he can be pastel and soft and still be badass and not be any less non-binary– and absolutely the Ghost King while being adorable and fluffy and rainbow.
So yeah. Basically Nico as the host of Anubis.
You can just see the autism huh
