RoboCrook is Carmen Sandiego's right hand man... er, robot. RoboCrook's history is a mystery, but one thing's clear: he'll do anything Carmen Sandiego or one of her villains tells him to do. His name is presumably a pun on that of RoboCop, a cyborg police officer. RoboCrook's real name, as mentioned in a phone conversation on the show, is "RoboCrook Unit-059". It was also revealed by the Chief in an episode that RoboCrook's birthplace is Cupertino, California, a town in the famous Silicon Valley.
