Sleuth "Doggy" Dawg was originally a member of the Robotropolis Spy Network, providing information to the various Freedom Fighter Groups from inside Robotropolis. However, Sleuth was swayed to Dr. Ivo Robotnik's side by promises of wealth and personal power. His attempted coup against Princess Sally Acorn was unsuccessful, and he was incarcerated at the Devil's Island Gulag prison. Upon his escape, he teamed up with several other prisoners to take his revenge, but they were roboticized by Dr. Eggman. After their de-roboticization by the Bem, the group had robot duplicates of themselves created by A.D.A.M. (aka Anonymous), and recordings in the wreckage of these machines showed the Destructix dealing with Anonymous. The real Sleuth has served with the Destructix since his de-roboticization,
