Hey there, I'm here with something new about this one in mind; percy j and the olympians together with naruto. Now this will be something like say where the other greek deities such as thanatos, eris, hypnos, and more so there would be taking naruto away to their world to live anew and a fresh start as their legacy or grandchild or whatever you wanted naruto to be and also, however there will be no pairings but may have some love interests and friendships. The same can be said about the settings or themes for this challenge like so:
Naruto the grandson of eris, the goddess of discord.
Naruto the legacy of hypnos and thanatos or the son of hypnos and the champion of thanatos.
Naruto the legacy of oceanus and thetys.
Naruto the grandson of triton and the champion of the queen (amphitrite).
Naruto the grandson of nyx and the legacy of chaos.
Naruto the son of hemera and the champion of erebus.
Naruto the son of hyperion or the grandson of hyperion via helios as a father, or selene.
Naruto the grandson or son of either gaia or rhea as say searching a new lover other than their former consort/husband.
Naruto the son or grandson of hestia, as a camp security/surveilance -like a guard dog or a watch dog-.
Now then, to start the story in the timeline of percy j, I would choose two books -the lightning thief- or -the sea of monsters-. But those dieties are either outside the olympian gods' rule or on their own isolated, away from their authority only observing and watching, keeping an eye on them and to keep them out of trouble. Also naruto can be either gray, dark (freeing his grandfather from tartarus) or as a guardian/protector of camp or domain.
Anyway, that's it for this challenge for now and please read & review, as well if you want you can pm me for permission to ask of them to either adopt or take'em as a challenge.
Farewell.
