Rouge the Bat | She's a vampire bat?!

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.

Rouge's origins or past remains largely a mystery, though at some point she gained an obsession with jewels and became a treasure hunter.

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. In Sonic Generations she is referred to as a temptress, due to her seductive ways. A gem-enthusiast, 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.

Rouge's carefree and playful devil-may-care attitude can be fun to some people, like the easygoing Sonic, or annoying for others, like the gruff Knuckles. 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.

Rouge can also show a bashful side, such as the time Knuckles saved her life from falling to her doom and became very embarrassed before concealing it with disgust, outrage, and ingratitude. She can also be a bit of a hypocrite, especially in regard to thefts. This is especially evident when, after witnessing the Master Emerald being stolen, she refers to the one stealing it as a thief despite the fact that she herself had stolen it from Knuckles earlier, something the echidna even noted by saying "Look who's calling who a thief", and in Grand Metropolis stage when she calls robots energy thieves.

Rouge is also at times a government spy who often works for her own gain. Rouge has a great obsession for jewels which she loves more than anything else, or even anything else that shines or glitters. Known to be a brilliant spy one minute and a gem-obsessed treasure hunter the next, she has little to no qualms about lying and manipulating others, often using her charms and attractiveness to seduce and take advantage of others, just to get what she wants. In truth though, below her outward demeanor, she possesses a kind heart. In fact, on many occasions, Rouge has shown she can be heroic, possess loyalty, care about others, or, at least, have some degree of morality. In the final events of Sonic Adventure 2, she helped save the planet from destruction. In Sonic Heroes, she jumped between Shadow and Omega's hectic fight as the mediator. In Sonic Battle, when Shadow was injured and needed a place to stay, Rouge helped him. In Shadow the Hedgehog, she did other laudable things, such as rescuing a Chaos Emerald from the doomed mainframe, destroying the evil monster Black Bull, and assisting Shadow in defeating Black Doom as well as showing concern for his welfare at the end of the game. She also is not fond of hearing Omega constantly talking about vengeance.

Rouge is partially a vampire and has a taste for blood, not specifically that of human blood but about any blood she can get her hands on. However, she doesn't go brute like and take it directly. She tends to flirt and charm her way into getting close to someone before bleeding them dry. The only people exempt from this are those she actually cares for.
