Formaggio comes off as a very relaxed individual. Unlike most of the pursuing assassins, Formaggio introduces himself openly to Narancia, trying to chit-chat, and laughing at his own jokes. Like the other assassins, Formaggio shows almost no regard for human life and is quite sadistic in tormenting his enemies. For instance, he has no problem pitting a shrunken Narancia against a spider. Despite this, Formaggio also has some standards.
