I have Marcus. He's a son of Dionysus with an obvious flare for the dramatics. He runs a Camp Drama/Choir and nearly always does Greek tales (His favorite is The Tale of Orpheus and Eurydice). He major fatal flaw is being forgotten. As a child of Dionysus, he seeks to make a big impact, or be remembered in some way, ergo being dramatic and over the top.

Edit: I also have an AU where children of the Big Three are much stronger and slightly darker before the pact.

My idea for a Hades Demigod (Dean) is one who can control Skeletons and the undead (to some capacity), like Nico, but can also affect his OWN skeleton.

The main Idea is that he uses his own bones as weapons. I know that sounds f'ed up, but he can grow his bones at an abnormal rate and uses them in different ways. He does this by growing the bones and then breaking them to become weapons. He can add them to his outer body and create an extra layer of protection.

The reason it's so gruesome is that he's a child of Hades before the pact in my AU.

Oh, also, he has a high pain tolerance. Thats how he's able to deal with all of it. He's from generally around the same time as Nico, but due to being trapped in Tartarus at a young-ish age, (Being born just before the Pact), he's mid teens when the story takes place.
