Iggy is a particularly unpleasant, unruly, and rude dog. For instance, he enjoys chewing on human hair and farting in human faces, antagonizing Jean Pierre Polnareff that way during his introductory arc.[6] He also plays a dirty prank on Jotaro as "revenge" for Jotaro throwing him into N'Doul. Having a free-spirited and irreverent nature, Iggy is often seen wandering away from the group and causing varying degrees of mayhem, mainly through stealing food.
