Name: Amy Rose

Gender: Female

Species: Mobian Hedgehog

Age: 19

Height: 2'11

Eyes: Bright green

Fur: Pink

Skin: Peach

Appearance: Anthropomorphic hedgehog with bright green eyes and peach skin covering her muzzle, inner ears and arms. She has a small black nose, triangular ears on top of her head, and no back spines. She has two medium-length eyelashes on each side of her eyes. She also has three spikes for bangs on her head and a short pointy tail.

Personality: Bold and fearless, Amy is a proactive go-getter that goes after what she wants and lets nothing get in her way. Likewise, she is an intuitive activist, which usually means she acts before thinking things through. Amy is described as an "energetic tomboy", though by the time of the Chaos incident, she is shown to have traditional feminine interests nonetheless, such as shopping and fashion. Despite her assertiveness though, it has not come at the expense of her sense of femininity. Amy also hates boredom and loves thrills and excitement; during her time in Station Square, she found her mundane city life dull and longed for the exhilaration of being a part of Sonic's adventures. Amy is very open and expressive about her feelings and emotions, always speaking her mind and never letting her feelings get bottled up inside. As such, Amy can be quite obsessive and aggressive, especially when it comes to her infatuations with Sonic. When angered, she has a habit of pulling out and threatening others with her Piko Piko Hammer, especially when anyone crosses her or hurts people she cares about. Amy has been shown as well to have no reservations about expressing more extreme emotions, be it either crying when overcome with sadness or not holding back in expressing her over-the-top enthusiasm. She has a massive crush on Sonic.

Name: Rouge the Bat

Gender: Female

Species: Mobian Bat

Age: 20

Height: 3'5

Eyes: Turquoise

Fur: White

Skin: Tan

Appearance: An anthropomorphic bat with white fur, turquoise-green eyes that have a pair of large eyelashes on each one, tan skin and a curvy figure. She has large pointy ears, small fangs, a small black nose on her muzzle, a short pointy tail and a pair of dark purple wings on her back. Only her head appears to have fur, which flares out into a sextet of points at the back. Rouge usually wears makeup consisting of powder-blue eyeshadow and pink lipstick. For attire, Rouge wears a black bodysuit which includes a skin-tight and strapless low-cut unitard that sports a pink and heart-shaped chestplate outlined with thin white-trimming. She also wears elbow-length white gloves and thigh-high high-heeled boots with pink cuffs to match them, with the latter featuring both gray soles and heels, along with steel toes in the appearance of pink hearts, matching her leotard's chestplate.

Personality: Rouge is a strong-minded female bat with a collected and convivial voice. Nothing short of an enigma, she is a person of many mysteries, always playing an active role on both sides of the truth in many global affairs. Her appeal is very complex, but it is not too far off to describe her as an elusive, mysterious, and mature woman who is true to her desires. To most people, Rouge appears as a brave, ambitious, independent, flirtatious, greedy, calculating narcissist who only thinks about herself and treasure. Rouge specializes in gem heists and gem-based treasure hunts, and has an unquenchable thirst for gemstones. The latter is due to a certain philosophy of hers: once you get a good gem, you will want a better one. However, a jewel that she cannot actually hold in her hand has no value to her, although a beautiful scenery matching the finest of jewels is equally valuable to her. While she may appear ditzy though, Rouge is in truth a cunning, calculative, and pragmatic realist; though she pretends to know nothing, she always manages to gets closer to the heart of the matter than anyone else; she shows lax behavior but manages to conduct delicate research; she can be on the enemy's side but then turn into a reliable ally while keeping her eyes on seizing the monetary prizes for herself. Overall, she has a way of taking off a figurative veil to reveal a dramatic new side of herself. Regardless, this unpredictable and mysterious aspect of Rouge may be her appeal.

Name: Blaze the Cat

Gender: Female

Species: Mobian Cat

Age: 24

Height: 3'1

Eyes: Gold

Fur: Lavender, violet, white

Appearance: A slim and lavender-furred anthropomorphic cat with golden eyes and a pair of long eyelashes on each one, a small black nose and a white-furred muzzle. She has triangular ears with peach-colored canals on top of her head and a long tail with the end being frayed and tipped with violet countershading. Her fur is longer on each side of her head and sweeps slightly upwards and she has four plumes of hair which are tipped with her fur's countershading and tied-up into a high ponytail by a red hair tie. She also has a red oval gem on her forehead. For attire, Blaze wears a gold collar hanging from her neck, a purple tailcoat uniform with rose trim at the bottom, white leggings, white gloves and rose high-heels, as both of them have white fluffy cuffs on them. Her heels also featured a thick white stripe on each of the front and gray soles and heels.

Personality: A noble soul and strong young lady, normally rather calm and solemn but tends to conceal her true feelings. Blaze is mannerly and typically maintains a relatively quiet and formal air among others. She also usually speaks in a polite and ladylike tone. While honored of her heritage as royalty, though, Blaze is down-to-earth and dislikes being called by her title. She has developed a keen intuition, allowing her to sense and see through the lies of others. She is amiable, friendly, and gentle towards others. She also came to understand the true meaning of friendship, making her willing to trust and accept help from others. While she still prefers handling things on her own and remains somewhat reclusive, she will accept her friends' help and is genuinely grateful for their aid. While Blaze gives the impression that she keeps her emotions in check, she is inwardly highly emotional. She possesses a fiery temper, and when she loses her composure she is quite aggressive, harsh, and prone to making bad decisions. She is similarly very serious about her position as guardian of the Sol Emeralds. Also, when dealing with enemies, she never holds back her strength and is not above the idea of using lethal force. She is usually highly disciplined and focused, never allowing herself to lose control, and can be quite stubborn and impatient once she has put her mind to something. Her intense demeanor, however, is motivated by her own genuine concern for others' safety. In truth, Blaze has a kind heart and always stands up for those who cannot stand up for themselves. After interacting with Cream, Amy and Sonic, Blaze has mellowed out considerably socially wise.

Name: Honey the Cat

Gender: Female

Species: Mobian Cat

Age: 19

Height: 3'1

Hair: Black

Eyes: Orange

Fur: Light amber, black

Skin: Peach

Appearance: A mobian cat with close-lying, light amber fur, a peach muzzle, and long jet-black hair that she keeps in two voluminous ponytails. She also has two triangular and perked ears with peach canals, a small black nose, small fangs, large orange eyes with two medium-length eyelashes on each one, thin arms and legs, and a slim tail with the end black. For attire, she wears a red hairband and elaborate white laced cloth-like hair barrettes around her ponytails, alongside a red sleeveless dress with a black collar and white laces on the lower rim. She also has a pair of white angel wings on the back, although it is unknown if they are real or not. Her dress also has a black sash around the waist, and a black area on her front skirt with white fasteners. Additionally, she wears white gloves with red backs and laced cuffs, black arm wrappers around her wrists, and red and black boots.

Personality: Honey is upbeat and friendly, but also a determined businesswoman; going to such lengths to join a fighting tournament in an effort to advertise her products. She has a very strong drive toward accomplishment, even taking up martial arts just for the sake of giving herself more to do between her work as a fashion designer and CEO of Honey Clothing. Even when facing a problem, she has enough confidence to somehow get around it. However, while she has noble intentions, she can be quite devious in battle. She appears to be the type of person who wants to put on a show for the people, as seen during the fighting tournament, she still put up a fight, regardless of her purpose to intentionally lose. Honey is quite the agile fighter. With her "Shadow Sneak" technique, she can move fast enough in short bursts to create the illusion of producing multiple copies of herself to confuse her opponent. She also has the skills of the fashion designer she is.

Chaos Emeralds: They are a septet of ancient gemstones tied to the Master Emerald that possess virtually infinite power. Those who hold them can use them to cause miracles and other feats, such as warping space and time and powering machines. The Emeralds give energy to all living things. Anyone who combines all seven Chaos Emeralds can harness unimaginable power and undergo a transformation into a heavily empowered form known as a Super State, through a process called Super Transformation. Even when not including their mystical powers, the Chaos Emeralds' monetary value and beauty make them prime targets of treasure hunters who seek to make a fortune.
