- "As long I don't see any strange events on the city or the Moonstone isn't shattered, everything's ok!"
- —Aria, telling Nixon and Hunter about her job.
Aria is an anthropomorphic hedgehog covered in light blue fur. It has a short peach colored muzzle, small nose, pointy ears, dark brown bangs that covers part of her face, one pair of eyelashes and conjoined eyeballs with a big sclera and one pair of narrow and oval shaped dark brown eyes. At her back of her head, there's about ten large quills, four on the left and right and two on the center. Her arms are peach colored, as well as her belly and chest (without her clothes). Her back consists of five back quills and a small pointy tail.
Her casual attire composes of blue and white pilot-like glasses on her head, a plain brown bandanna around her neck, a grey white stripped sleeve shirt and a brown belt on her waist. She wears a pair of brown hiking shoes, with the white socks exposed.
Aria is shy and kind but responsible hedgehog, whose job is to guard the Moonstone Pearl in Moonstone Temple, located in her birthplace, Jewel at Palm Seaside Zone. It can be very cautious and alert at her surroundings, when someone approaches to her, will start fight them with her knifes. Aria can be often can be seen with her brothers, Nixon and Hunter, hanging on together playing videogames on the Temple.
When surrounding with strangers, Aria often is extremely shy and self-conscious. Can be seen as serious and calm individual. Due for her shyness and introversion, she has difficulty making friends. Away from places filled with people, she chooses locations such as abandoned places or natural scenery, like beaches and rainforests. At that state, she is much calmer and easygoing with everyone else, but still very shy of strangers. When Aria is very joyful and happy, can be heard singing, often about her favorite songs. It sings it when no one is around, so others can't listen to her voice.
Sometimes, Aria can be dreamy and clumsy. It can get into trouble, especially with Corinna Nicasio, her short-tempered mother. When dealing with her mother, Aria turns short-tempered as well, forming a fight between her and Corinna. Often happens when Aria is doing some task for her and she makes her angry due for the bad job Aria made for her. The fights between them are common and unavoidable, Aria hates people who are short-tempered.
Like Amy Rose, Aria has a crush on Sonic The Hedgehog. She is infatuated as Amy but avoids chasing or following him. Whenever Sonic is near Aria, she can be quite the opposite: escaping from him. Aria can blush at seeing her crush but is embarrassed at the same time, and as a result, can escape from him by herself.
Aria is a tomboy, who tends to hate girly things. It nicknamed "Tomboy" by Hunter Darryl and Corinna Nicasio. Corinna, the opposite of her tomboy personality, forces her to wear more feminine clothing and act more girly, but she refuses to do it. She does boy-ish activities, like playing video games and not applying make-up. Also likes to be away from her mother, to avoid such fights.
It can be short-tempered when she encounters with her foes, especially with Dr. Eggman. Such hate comes from destroying the ecosystem to the hate on the heroes who want to fight for the good. As a hero, she fights for the good for everyone. Sometimes, she can be sarcastic over him during these encounters. Aria are foes with Amy Rose, Shadow, and July The Gull.
Aria was the first daughter of Corinna and Zoran, their parents. Was born on a near hospital on Jewel. Was originally light brown, with many quills spiking from her back and head. After passing many tests for the baby's health made by the doctors, they found and informed to the parents that Aria has an "defect" on one of her genes. Both parents started to worry about her, thinking it may be a genetic disorder what will make her life more difficult. Surprisingly, Aria developed very well and had a normal life.
As Aria grows older, the light brown fur slowly started to turn to light blue and the quills are becoming to fuse together. The phenomenon of this is unknown, it occurred when she was about 4 years old. Her mother started to concern about it, thinking it was the defective gene that make her change her appearance and it possibly be a disorder. Her father, however, thought differently, saying to his wife that it inherited one of his abilities to her. It wasn't defective at all, rather its a mutation that makes her different to others on the city.
She entered school for the first time at 5. That when she meets July The Gull, an old foe. July often criticizes about how bad she is, looks weird, and etc. Annoyed by her insults, they often fight each other on classroom. The teacher deal these fights between July and Aria most of the time. Sometimes may get into the office to resolve the issues, with parents involved. At 8, July left the school, leaving her alleviated and not having to deal with her again. During school days, Aria started to develop her own personality, the teacher described her as calm, serious and shy during the meeting with their parents.
At 12, their parents decided to take Aria away from school and start to homeschool her. Now comfortable with her new style of learning, she is more free than before. Also, the fur and quill transformation was complete, giving a new look to her. Since that "new chapter", she decided to add more activities, such as helping people and importantly, guarding the precious Moonstone Pearl every afternoon. Still shy around others, she started to socialize with others, in order to overcome her shyness, but so far, she doesn't have friends yet.
Aria's only known power is the capability to form a strong tornado. In order to work, she must be of a flat and big surface. By running on circles at fast speeds, starts to form a whirlwind, but isn't strong enough to make sufficient damage. If it continues running, the effect will be more noticeable and stronger, thus forming the Typhoon Tornado. At its maximum capacity, it will overcome the winds of a typhoon but almost to a tornado's wind speed. Aria need to use this wisely, in order to avoid damage from cities and historical structures.
One of Aria's abilities is running at supersonic speeds, however her speed has a time limit and is much slower than Sonic. When it reaches the time limit, she will start to get tired of running. It was originated through genetic heredity from her father, which has the same power. She uses this power in advantage to escape from powerful enemies and natural disasters, such as a tsunami. Her time limit has been improving over time, with the radiating energy of the Moonstone Pearl and the constant use of her power, resulting in longer time running. She can run a maximum speed of 356mph.
Also it has direction swiftness, which allows her to move very quickly from one direction to another very fast. Makes it quite impossible to hit her, and makes Aria a greater chance to stop an enemy from fighting and disable the chance to fight her. If done correctly, defeating them can be very easy, but it depends on how strong the enemy is and the type.
Aria can be really sneaky, without noticing that she's really here. Although makes it perfect for stealing stuff, she isn't that type of person who steals precious stuff, however she sometime steals items, depending on the importance of the item for a certain mission or function of some machine. Her light footsteps makes no noise, making useful for not disturbing others.
Other of her skills is singing. She often sings alone, where no one is near her, due to her fear that someone will negatively tell her about her voice. Her favorite places to sing is at forests and beaches, where she most comfortable and happier. Most of the time, she will sing her favorite songs, like this and this one.
Since she started at the age of 4, her drawings have evolved dramatically. Her first drawing is just red scribbles, drawn on a wall. Later, began to draw more, until the biggest improvement took place at school, where she made herself a challenge to draw the closest drawing to the original. Some people loved how she draws, so Aria decided to keep up, also was turned into one of her favorite hobbies. Now with her sketchbook she brought from an art store, now can draw and keep her sketches on one place safely. Until now, she mostly draws landscapes and her crush, Sonic.
Her biggest weakness is her lack of social skills and her extreme shyness. She can't even start at conversation, always has no topic to talk about. Also may talk way too low sometimes, making hard to listen what she was saying. Also has be shown to have interest to specific people, but have problems how she going to express herself and thinking a lot what is going to say to them.
Also can be very forgetful sometimes, making her prone to forget most things. That should be a disadvantage, especially when remembering some important events. That occurs when is focus is on one thing completely, forgetting everyone else. She has a short-term memory for most things, like what money she has, or what learned at school (except she's interested on something).
