In mid-1999, Mysterio and Konnan joined Master P's No Limit Soldiers, and began feuding with The West Texas Rednecks. At The Great American Bash, they defeated Rednecks members Curt Hennig and Bobby Duncum Jr. in a tag team match. At Bash at the Beach, they defeated the Rednecks in a four-on-four elimination tag team match when Mysterio pinned Hennig. After Master P's departure from WCW, Mysterio formed a stable with Eddie Guerrero and Billy Kidman known as the Filthy Animals, thus turning heel in the process. This was Mysterio's only heel turn in his career. The three wrestlers soon began a feud with the Dead Pool. The Filthy Animals defeated the Dead Pool in a six-man tag team match at Road Wild and at Fall Brawl. On the August 19 episode of "Thunder", Mysterio lost the Cruiserweight Title to Lenny Lane.
