Harley

Harley is a demigod son of Hephaestus. He is only 8 or 9 years old.

The Lost Hero
He is introduced when Leo visits the forges in The Lost Hero. He is the youngest member of the Hephaestus cabin. Leo states that "even little Harley looks like he could probably go six rounds with Chuck Norris without breaking a sweat." The only time he is seen, he is depressed because of the Curse. He has many siblings, including Leo, Nyssa, Christopher, and Jake Mason. Leo states that all of the kids in this cabin look different, saying, "You'd never think, 'Hey! It's the Hephaestus bunch!'" Harley has his own room in the cabin and is great with his hands. His hands are large and calloused, unlike Leo, who, being a fire user, has fingers that are long and thin.
