Rouge the Bat (ルージュ・ザ・バット Rūju za Batto?) is a fictional character from the Sonic the Hedgehog series who first appeared in Sonic Adventure 2. She is an eighteen-year-old anthropomorphic bat and jewel thief working as a part-time government spy for the President of the United Federation and an agent on loan for the Guardian Units of Nations. A world-famous freelance treasure hunter, Rouge has a weakness for jewels, especially large 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 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.
