Prince Doza, known as Prince Naseem (PRINCEナジーム) in Japan, is a character from Ehrgeiz. His motto is, "I’ll destroy anyone who stands in my path!" Each day, Doza seeks a more powerful opponent. However, in the world of Kickboxing, he is already without equal. Able to defeat his opponents with his bare fists, Doza has become bored and is in need of a challenge. In the midst of his unrest, he receives word of the Ehrgeiz tournament, where weapons, psychic powers, and projectile weapons are permitted. Thrilled, he is determined to test his skills. Although he has no interest in the secret that Ehrgeiz holds, his fighting spirit is fueled by the appearance of opponents that are more powerful than he has ever imagined.
