"Iron" Leo, a nickname given to him due to both his thick armor and his will in battle, is one of the renowned Six Knights of Zexen, and the mightiest physically of them all. He attacks with a broad axe, which gives him great power. He blames himself inside for death of Captain Galahad, the predecessor of Chris; and so he feels an even greater duty to protect Chris, the new Captain of the Zexen Knights. - KoRnholio
