Donatello Versus

Donatello Versace is an antagonist who appears in Part VI: Stone Ocean. He is the illegitimate son of Dio Brando, and the half-brother of Ungaro, Rykiel, and Giorno Giovanna.

Story
It dawns on him during the chapter "Underworld Part 4" that all of his suffering as a young man was because of his stand power Underworld, which was at the time, undeveloped. However, Enrico Pucci helped Versace train this power and let it develop. Even so, Versace explains in a monologue that he wouldn't hesitate to attack Pucci, holding a grudge against him because of how high Pucci thinks of himself.

Past
Versace was raised by his mother and stepfather, a man who "did nothing but tell long stories of his womanizing ways," who his mother married at an unknown point in Versace's life.

After running away from home at age 13, a pair of baseball shoes fell from the sky onto his head. He put them on, but was soon arrested and taken to court, where he learned the shoes belonged to real-life Seattle Mariners outfielder Ichiro Suzuki, originally to be given to disabled children as a gift.

Upon telling the truth that the shoes fell from the sky, the judge flew into a rage, disgusted by the fact that a 13-year-old boy would stoop so low as to steal from children less fortunate than himself. Versace was quickly deemed guilty on circumstantial evidence of stealing the shoes and was sent to a juvenile detention facility for six months, Versace's mother and stepfather not objecting to his incarceration.

However, four months after Versace's arrest, the true criminal confessed. The criminal was a professional burglar, who, after stealing the shoes, was afraid that he would be caught because the shoes were so famous, and dropped the shoes down a ventilation shaft on top of a building to get rid of them.

When word reached the facility he was being held in that he had been wrongly condemned, Versace had already been physically and emotionally drained, and he was almost too weak to even move because of a string of strange events that had occurred over the course of his incarceration. For instance, Versace tripped while walking in the field of the facility and his hand was impaled by a knife that had been buried there some time before. Versace would find out the next day that the knife belonged to a corrupt guard who had been hiding it, presumably to threaten other inmates. As a result of this, the guard bullied and beat Versace regularly. His hand wound was finally treated two weeks after the fact, but worms and pus still infested the wound. Possibly as a result of this, Versace fell into a fever and nearly died. Another occurrence was that Versace urinated on a decrepit wall that crumbled and revealed the skeleton of a long-dead woman.

However, during the events of Stone Ocean, Enrico Pucci took Versace and two of Dio's other sons, his half-brothers Ungaro and Rykiel, under his wing and helped them develop their stand powers.

Trivia

 * Versace's backstory is either an homage or a direct lift from the novel (and later feature film) "Holes," written by Louis Sachar, in which the protagonist Stanley Yelnats IV is sent to a juvenile correction camp called Camp Green Lake, after the sneakers of fictional baseball star Clyde "Sweet Feet" Livingston fall from the sky onto his head. As it turns out the sneakers were to be auctioned off, the proceeds going to orphans.
