Rouge the Bat is a major character in Sega's Sonic the Hedgehog franchise. She is an anthropomorphic bat and treasure hunter who can find the pieces of the Master Emerald just like Knuckles, her rival. She is a government agent (working for G.U.N.), a self-proclaimed treasure hunter and jewel thief who plans to make all the gems and treasures of the world hers.

Her current jewel obsessions are the Master Emerald and Chaos Emeralds. She is Shadow and Omega's best friend and Knuckles and Amy's archrival. Despite her rivalry with Knuckles, they have a secret crush on each other. In the current and new games, Rouge is 18 years old. In the early 2000s Sonic games, she was originally 17.
