Luke comes off as a really nice and observant young teen. Being one of the older demigods at Camp Half-Blood he is full of a surprising amount of wisdom that he is not afraid to show off. He is very supportive of the younger less experienced demigods such as Percy Jackson and Annabeth Chase and does everything he can to be helpful in their journey. Due to his resentment towards his father, Hermes, Kronos is able to manipulate him and sway him to his side.
