Alessi is a sadistic, yet cowardly man who will only fight those who are weaker than him. He takes extreme pleasure in taunting and humiliating his opponents before finishing them off, and will exploit any underhanded method to gain an unfair advantage. Despite this cowardice he has an odd sense of pride, and will go out of his way to take revenge on those who humiliate him, even if it leaves him vulnerable. The mercenary's mental competence is further brought into question with his strange logic, when he claims that "people who always say that they are weird aren't actually weird... So I'm not weird." His stand Sethan is named after the Egyptian God of Tornadoes and Storms.
