Kratos is typically characterized as brutal and merciless, often engaging in morally ambiguous activities and performing acts of extreme violence. He is also portrayed as being stoic, bloodthirsty, and arrogant in nature. However, despite his seemingly fearless facade, he frequently questions himself, undergoes bouts of severe guilt and self-hate, and is generally portrayed as a tragic figure. Vengeance is a central theme of the series, with Kratos seeking revenge against those who have wronged.
