He has a rather disturbing personality: he is extremely rude and impolite, showing neither respect nor mercy for people and animals, as they are beings that he only sees as food for his Yellow Temperance. He does not seem to be particularly intelligent and he is easily angered. He wanted to ambush Jotaro with Kakyoin's appearance, but his unusual behavior blew his cover. He is also narcissistic and arrogant, referring to himself as handsome. He's also slightly perverted.
