Iggy

Iggy, who possessed the powers of a Stand, was found by Muhammad Avdol in the street slums of New York. Only Avdol is able to come close to him.

He is remembered for his obsession for coffee-flavored chewing gum and for antagonizing Jean Pierre Polnareff in the series. Iggy also sported the most unsociable traits ever in a dog, as he will fart on a person's face while chewing and ripping out their hair.
