Ethan Nakamura

Ethan is a teenage boy of Japanese descent and looks to be around sixteen years old. He had a thin build, glossy black hair, and a black eye patch over his left eye. As an enemy demigod in Kronos' army, he was generally seen wearing Greek armor; according to Percy, it hung on his body loosely due to his slim build.

Ethan was a brave, impetuous boy who was very driven by his goals, and according to Percy he was a well-trained fighter. He followed his goals and tried to achieve them the best way he could, even if it means betraying those he previously allied with. Like his mother, Ethan had a strong urge to bring balance to things, feeling that the minor gods deserved more respect and eventually paid Percy back for saving his life.

Ethan is the demigod son of Nemesis and he resides in Camp Half-Blood, a camp for Greek demigods. He lives in cabin number 13, the cabin for children of Nemesis. So far he is the only child of Nemesis in the cabin.
