Percy Jackson MC idea the cross weaved demigod

Basically the idea for this character is that two lines of families had been marrying into unpowered children of demigods from multiple Pantheon's and none of the children have any kind of Supernatural powers their powers or domains or whatever you would call it and I've been building up for centuries now those two families come together in the main characters father or mother which now only needs a spark to ignite all those powers and domains basically the father or mother hook up with your chosen god or goddess(I would choose the Greek pantheon for the parent) and that Sparks off the main character who has a mix of multiple powers and domains in which causes him to be targeted by a multitude of Pantheon's and people from them to either harm him or help him

I explained the character this way so whoever chooses to write this main character can pick and choose which powers he got whether they give him the weak version or the truly powerful version of each powers or maybe even give him only a massive amount of weak powers to make him extremely versatile but not power hitter and how many gods and which gods and goddesses of each Pantheon
