*Rouge the Bat is a character that appears in the Sonic the Hedgehog series. She is an anthropomorphic bat and jewel thief who has worked as a part-time government spy for the President of the United Federation and in close association with the Guardian Units of Nations. A world-famous treasure hunter, Rouge has a weakness for jewels, like the Master Emerald and Chaos Emeralds, which she always obsesses about. As a spy, Rouge is trained in combat, stealth and infiltration, and possesses both super-level kicking power and flight.

Rouge is in short, an enigma, as her motivations are always in question. In truth, she is usually just out for herself. She is incredibly smart, sassy, and seductive, and knows how to get what she wants. Once she has a target in mind, she always goes for it, regardless of the costs. Beneath her ditsy exterior though, she is a calculating realist and her motives are always mercenary in nature. Regardless, she is loyal to her closest friends and has more than once helped Sonic the Hedgehog and his allies save the world.

Rouge is an anthropomorphic bat with white fur, turquoise-green eyes with two 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 six 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, 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.

Recently, she has been seen less selfish, as can be seen by her actions towards Shadow in Sonic the Hedgehog (2006) and Sonic Rivals. However, as shown in her portrayal in Sonic Free Riders, which depicts her as very cold and callous from her desire for the cash prize, suggesting she still possesses her interest in jewels and riches. This is proved as she couldn't care less that E-10000B broke down and even went on to insult it as well.

Cunning, confident, sassy and fearless, Rouge knows how to get what she wants. While she might appear to be ditsy and carefree at first glance, her mind is always actively scheming and making up new strategic plans. A calculating and manipulative realist who can arrange situations to go the way she wants them to, she acts mainly on her mercenary instincts. Because her motivations do not always appear as what they seem at first, Rouge is quite enigmatic, and her intentions are not always entirely clear.

Rouge is an ideal spy, able to be cunning, manipulative, deceitful, strategic, observational and tactful at the drop of a hat, such as when she delayed Shadow from finding Eggman and tipped off the Chaotix to Eggman's location, all to bring in Sonic to reign in Shadow and keep the situation from getting too violent. This suggests a more compassionate side to her, or at least that she is not narrow-sighted or willing to act without a full story. Also, despite her profession as a jewel thief/treasure hunter, Rouge is not completely selfish, though she also sees good deeds as ways to achieve her personal goals. She is likewise fond of riches and jewels, such as the Master Emerald. For this reason, she is ready to help defend the world so there will be a civilization in which she can live the high life. Nonetheless, her compassionate side does show up at times, and she will not hesitate to protect those in need, showing a selfless side beneath. However, she does not consider herself a type of person who will sacrifice herself for the greater good, nor someone who is too helpful.*
