This is a list of fictional characters in the Carmen Sandiego series.
The ACME Detective Agency or ACME Crimenet (changed to ACME Timenet in Where in Time Is Carmen Sandiego?) is the organization that the user or protagonists always work for. The exact nature of the organization is never explained, but it appears to be concerned mainly with tracking down and capturing international criminals. ACME trains and employs agents who act as detectives, spies, and double agents against V.I.L.E.
Although the structure of ACME Headquarters varies, it is always located in San Francisco, often being depicted as well within view of San Franciscan landmarks such as the Transamerica Pyramid and the Golden Gate Bridge. Additionally, ACME usually has numerous field offices around the globe. An ACME training academy of some kind is often stated or alluded to exist, presumably located at its San Francisco headquarters.
The leader of ACME is called "The Chief", though the nature of the character varies considerably in different media. The character is never given a name beyond that title. In the original first few computer games "the Chief" was a mysterious male figure hidden in the shadows who had very little personality or role. No Chief character appears in Carmen Sandiego's Think Quick Challenge, Carmen Sandiego Word Detective and Carmen Sandiego Math Detective. The most notable "Chiefs" were the live-action Chief played by Lynne Thigpen and the Holographic Chief of Where on Earth is Carmen Sandiego? voiced by Rodger Bumpass.
In the PBS game shows Where in the World Is Carmen Sandiego? and Where in Time Is Carmen Sandiego?, the Chief became a more dynamic character. Played by Lynne Thigpen, the Chief was a comically no-nonsense figure with a strong sense of justice who spoke with dialogue that was riddled with puns, alliteration and other forms of word play. Her catch phrase was "I salute you," which she often uttered while holding a magnifying glass over her eye. According to the World episode "The Canal Caper," her great-grandmother, Agnes Acme, is the founder of ACME. Agnes Acme was also played by Thigpen and is apparently deceased, though that didn't stop her from providing clues.
