"Carmen Sandiego is a fictional character featured in a long-running edutainment series of the same name. As a criminal mastermind and the elusive nemesis of the ACME Detective Agency, Sandiego is the principal villain of the series and head of ACME's rival organization V.I.L.E. Most of her crimes involve spectacular and often impossible cases of theft. Her full name, according to Where in the World Is Carmen Sandiego? Treasures of Knowledge, is Carmen Isabella Sandiego.
Carmen Sandiego is almost always portrayed with a red trench coat, a matching fedora and long brown hair, although her hair color was given to be "auburn" or "black" in some of the earliest games. Her fedora is often shown leaving her face in shadow and obscuring her eyes. When her eyes are visible, they are usually brown, although they were blue in Where on Earth is Carmen Sandiego? and in Carmen Sandiego Math Detective. In many appearances she also wears gray or black gloves."
