Valentino has been described as being charming and roughly as level-headed as his fellow Overlord, Vox. When he interacts with Charlie in his studio he acts cordial around her while struggling to hide his anger and irritation that he would prefer to take out on one of his employees instead, such as Angel Dust. He does, eventually, show off his real behavior after some time. Valentino uses his charming persona in order to lure other demons into working for him, as shown in "Welcome to Heaven" where Valentino admitted spending much of his time in nightclubs, picking up demons and offering them "jobs" at his studios, with him hiding his more violent and psychotic behavior in order to convince them to willingly "work" for him.
