Donatello Lorenzo was born on June 21 to Guila and Piero Bellucci in Lucca, Italy. He was the fourth born of the children, but only by a mere couple of minutes. Soon after Nate was born, their mother gave birth to his twin Dante. After the twins came their youngest brother Nico, but his life came at the expense of Guila's. The birth had taken their mother's life. Their father was left to raise a newborn babe, a set of toddler twins, and three more children alone.
With their father struggling with six children, he turned to always asking neighbors for help, and to drinking for relief. After showing growing signs of instability, one of the neighbors had taken the children, and called protective services. That was when the children were thrown into the foster care system. Donatello was still young at the time and had a hard time understanding what was going on. His mortal fear was to be separated from his siblings - especially Dante. But luckily, Aurora found a way to convince the foster care system to keep them all together.
Before the younger kids were able to attend Beauxbatons, the family moved to England, and were prepared to attend Hogwarts instead. Nate had his first magic sign at the young age of six when he was pulling a prank on Stefano. He had set up a small paint bucket over the door way to fall on top of his brother when he should open the door. Unfortunately for Donatello, Stefano predicted his prank and side-stepped the bucket. Unfortanately for Stefano, he didn't predict his brother utilizing magic to move the bucket mid-fall to land right on him. Nate thought it was hilarious. Stef thought he was going to go to jail for murder.
The foster families that had followed their father's abandonment of the children were less than ideal. Some were right-out abusive, other neglectful, and some clearly favoring their blood-related children. Overall, the Bellucci kids had to protect each other. It was them against the world. Despite their bad circumstances, the twins were actually good kids. Sure, they were mischeivous, but they had good souls. Nate always had a better outlook than Dante though. He looked for the best in people, but was often let down time and time again.
The Bellucci family is known to produce very powerful wizards as well as some of the weakest - they are quite the anomaly. Luckily, the twins were gifted with great power. Such great power that when they got older, 15 to be exact, they were able to accomplish something incredible for wizards, let alone wizards of their age. They conquered the skill of transforming into an animagi. The pair could transform into Siamese Cats that looked identical, save for a few minor differences. They've never registered with the Ministry however, and they keep their ability on the down low. They hope to keep it that way.
Over the years, their eldest sister Aurora grew increasingly protective of the family, and eventually attempted to gain custody over her younger siblings but was refused. Soon enough, Donatello and Dante were old enough to go to Hogwarts and escape their unfortunate home life for a while. Eventually, circumstances allowed Aurora to follow through with gaining custody and the Bellucci kids all moved into her apartment in Lincliff. Happily Ever After, right? Nate sure hopes so.
