Natalia's daughter. She can almost always be found playing with her brother, Elio. Lucia exercises regularly so as not to follow in her mother's footsteps, but is much too considerate to mention that to her pudgy mum.

Lucia (ルチア Ruchia?) is a character that appears in Sonic Unleashed. She is a human resident of Spagonia, the daughter of Natalia and Ciccio, and as well the little sister of Elio, whom she often hangs out with.
Lucia was born as the daughter to Natalia and Ciccio. As she grew up, Lucia did not want to follow in her mother's footsteps and become overweight as she grew older, and began exercising regularly and not eating much food, though she still ate enough to remain healthy, in order to prevent it. She was, however, considerate enough about her mother's feelings not to mention her reason for her choice of lifestyle to her.
During the events of Sonic Unleashed, Lucia encountered Sonic the Hedgehog and Chip when they first arrived in Spagonia to find Professor Pickle. As Sonic and Chip asked Lucia for directions to Spagonia University, Lucia told the duo that while she did not know how to lead them all the way to the university, she was able to guide them in the general direction before they then would have to ask someone else. Later on, when Sonic and Chip were asking for clues to Professor Pickles' whereabouts and met Mauro, who talked rudely to them, Lucia remarked to Sonic and Chip that she thought Mauro was a brat for the way he was talking to them and told them how he was pranking Denise.
At some point, Lucia and Elio realized that their mother's birthday was coming up, and they decided to work together to give Natalia the best birthday ever. The two of them then came up with the idea that they should try to make their mother as beautiful as she was during her modeling days as their birthday gift to her. They then formulated a secret plan between them, where Elio would collect enough Rings to buy their mother a nice piece of jewelry, and Lucia would steal her mother's food and eat it, so that Natalia would chase Lucia and get some exercise. Later, when Sonic had saved Professor Pickle, Lucia met Sonic and Chip and told Sonic that she wanted to know how he saved Pickle, but then remarked that she was too busy at the moment to hear about it.
Lucia's part of the plan proved to be hard for her, as she would often get a stomach ache from eating all Natalia's food. Whenever she met up with Elio to confirm the progress of the plan, she would complain about his part being the easy one. Eventually, it became harder for Lucia to get her mother to chase after her and was caught by Sonic, who had been assigned by her to catch her, after one of her raids. After being caught by Sonic, Lucia was scolded by her mother for stealing her food, and Lucia would promise that she would not do it again, though she could not keep her promise or tell her why she did this. Eventually, Lucia told about her Elio's plan to Sonic, but made him promise not to tell anyone.
As Natalia's birthday came closer, Lucia could no longer make her mother chase after her, and she and Elio decided to abandon their "forced diet" part of their plan. Unfortunately, Elio had lost the Rings he had collected, but Lucia found Sonic and asked him panicky to help her brother round up more Rings. After Sonic managed to gather enough Rings, Lucia joyfully thanked Sonic for his help.
With enough Rings, Lucia and Elio decided to focus on their mother's present and started to think about what they should give her. Lucia suggested things such as a new house or a mini-skirt, but she decided to go with her brother's nice idea of a finger ring. Unfortunately, all the pieces of jewelry they could find were too expensive, and Lucia told Sonic and Chip when they met them that she was about to give up on their plan entirely. To Lucia's surprise however, Sonic soon after returned with the finger ring from Aida's shop that they wanted to give their mother, which he got after he had returned Aida's favorite necklace which Elio had found, and Lucia was amazed that people could buy such stuff.
Now with a present, Lucia and Elio decided that they should celebrate their mother birthday at Restaurant Swa where they would have dinner. They were, however, unable to make a reservation as the shop was closed, due to the owner Gigi having troubles coming up with new recipes. While waiting, Lucia met up with Sonic and Chip again, and told them that she hoped that Gigi would be done before her mother's birthday was over. Fortunately, thanks to Sonic, Gigi reopened the restaurant in time, and Lucia and Elio could make their reservation. Afterwards, Lucia met Sonic and Chip again and told them that she could hardly wait until her mother's birthday.
During the evening on their mother's birthday Lucia and Elio made their father wait in front of the restaurant and Lucia waited faithfully alongside him, while her brother brought their mother to the restaurant. Not long after, Natalia arrived, and, together with her family, Lucia celebrated her mother's birthday, who was overjoyed and thanked both her and Elio for the best birthday ever.
After the birthday, Lucia thanked Sonic for all his help with their mother's birthday and remarked, though cheerful, that it was kind of bad that their diet strategy did not work.
On the PS2/Wii version of Sonic Unleashed, Lucia is one of the Temple Guardians of Spagonia's Gaia Temple, alongside Otto, and her job is to both guard the temple and as well lead the ones who are worthy to enter them. At some point prior to Sonic Unleashed, she was given the Moon Tablet to Spagonia's Gaia Gate by her grandfather, which she believed was a charm.
During the events of Sonic Unleashed, Lucia, alongside Ippolita, met Sonic the Hedgehog and Chip when the duo first arrived in Spagonia to find Professor Pickle, who asked them where to fond Professor Pickles' laboratory, but Lucia had no clue of where it was. Sonic then asked her if her "sister" (Ippolita) knew where it was, but Lucia told them that Ippolita was just her friend's sister.
Some time later, Lucia and Ippolita were approached by Sonic and Chip again, who asked them where they could find the Sacred Shrine. Lucia recognized what they were talking about and provided them with directions. Lucia then told them that strange things had been going on in that area, and tried to give them her Moon Tablet. Sonic and Chip told her that she should not have, but she insisted as she believed that they would need it.
After Sonic and Chip restored Spagonia's continent, Lucia brought Sonic and Chip to Ippolita, who wanted to give them a present.
Lucia exercises on a regular basis so that she does not become overweight like her mother, though she is considerate enough not to mention it to her.
