Rouge the Bat is a 3 ft 5 in Mobian bat from Sonic the Hedgehog who works as a part-time government agent and occasional jewel thief. She has white fur, tan skin, turquoise eyes, and wears a black jumpsuit with a pink and white heart chest plate. Rouge is 105 cm tall and wears white gloves and knee-high boots with pink cuffs and heart tips. She also wears powder blue eyeshadow and pink lipstick but she's also a confident, slightly vain, and deviously intelligent character in the Sonic the Hedgehog universe.

She's known for her flirty nature and love of jewels, but also displays a compassionate side and takes her job and the safety of the world seriously. She's a treasure thief who enjoys flirting with characters like Knuckles, Sonic, and Shadow, often using her feminine wiles to manipulate or distract.
