A former supermodel whose looks could floor anybody. She's still beautiful; a loving mother of two and a source of strength for her shoemaker husband, Ciccio. Natalia makes a mean cheese pizza. — Directory, Sonic Unleashed
Several years prior to Sonic Unleashed, Natalia was a highly successful supermodel whose beauty could stun anybody. As such, Natalia found her surrounded by many suitors, but she rejected them all. Eventually, however, Natalia fell in love with a young Ciccio. Sometime afterwards, Natalia found herself proposed to by Ciccio with a lovely blend of flowers. She accepted his proposal, and the two of them got married.
After some time, Natalia became the mother of two children; first a boy they named Elio, and later a girl they named Lucia. Over the years, Natalia developed an insatiable appetite for food, and she eventually lost her slim figure and became overweight. She did not let the loss of her figure get to her though, and continued to be a loving mother and strong support for her husband. As she could no longer be a model, Natalia began to work in hers and Ciccio's shoeshop, where they became well acquainted with Professor Pickle.
Some time before the events of Sonic Unleashed, Natalia heard from Elio that he had seen Professor Pickle being kidnapped, but she did not believe him. After the Earth was shattered following Dark Gaia's awakening, Natalia saw Sonic the Hedgehog, Miles "Tails" Prower and Chip arrive in Spagonia to see Professor Pickle, and asked them how they could travel to Spagonia with the planet in pieces, and wondered if they had their own airplane or something. Later, when Sonic and Chip were asking around town for clues to Professor Pickles' whereabouts, Natalia told them not to listen to Elio, as she thought her son was lying.
When Sonic, Chip and Tails returned with Professor Pickle from Mazuri, Natalia heard how they saved Professor, and later met up with Sonic and Chip to tell them how relieved she was to hear Professor Pickle was alright and explained how she knew Professor Pickle. She also told them that thinking about Professor Pickle’s travels made her think that if she traveled to the places he did, it would make her hungry.
During the following days, Natalia began to notice that her children was acting strange: Elio had begun to go out at night, which made Ciccio worried, and she would often ask Sonic and Chip when they came by if they had seen Elio. Likewise, Lucia had begun to eat her food, which made Natalia angry and chase after Lucia who always tried to run away. One day, after Lucia had stolen her food again, Natalia met up with Sonic again, and she asked Sonic if he could catch Lucia for her as she could not run so fast. Sonic agreed to help her, and Natalia thanked him. After Sonic brought back Lucia, Natalia could not understand where Lucia got her appetite, and she told her that she would make some food for her as long as she did not steal hers. While Lucia promised Natalia she would not do it again, she would resume her ways and Natalia continued to get mad and chase after her.
As time passed, Natalia could not figure out why her children was not listening to her. Things later became more frustrating for Natalia as her children was not doing their chores and that Ciccio had begun to be too lenient with the kids, which led to her believing that they had something on him. Whenever Sonic and Chip came by in this period, Natalia would talk with them about what had happen.
Eventually, Natalia became so worn down by Lucia constant thefts of her food that she could not chase after her or get mad at her anymore. She also started to notice that her husband had begun to act downright strange as well and wondered what was wrong with her family. Whenever Sonic and Chip came by in this period, Natalia would tell them of what had happen and express her worries to them.
One night, Natalia was approached by Sonic who told her to go to Restaurant Swa as Elio was waiting for her there. Thanked Sonic for the heads-up, Natalia left to figure things out. When Natalia arrived at the restaurant, she found Ciccio, Elio and Lucia waiting for her and learned that the reason they were acting strange was because they were preparing for her birthday; Elio was trying to buy her jewelry, Lucia was trying to make exercise to make her slim again, Ciccio had been trying to buy her flowers, and both Elio and Lucia had made reservation at Restaurant Swa to celebrate her birthday here. Touched by her family's consideration, Natalia thanked them for the best birthday ever, while crying in joy.
After the birthday party, Natalia thanked Sonic for his help in making her birthday so special. She also said a little embraced that she had been trying to go on a diet since her birthday, but have failed since she got so hungry.
