Killings was then promoted to the main roster and put in a tag team with Road Dogg. He debuted on the November 13, 2000 episode of Raw is War, attacking William Regal during a match against Road Dogg. Killings and the Road Dogg began rapping together, performing a song called "Gettin' Rowdy" as they approached the ring. Upon the return of Road Dogg's former partner Billy Gunn later that month, Killings was involved in a D-Generation X quasi-reunion. At Survivor Series, Killings teamed with former DX members Road Dogg, Billy Gunn, and Chyna to face The Radicalz in a Survivor Series match. Killings was eliminated and the Radicalz went on to win the match. At Armageddon, Killings and the Road Dogg took part in a four-way tag team match for the Tag Team Championship, which was won by Edge and Christian. After Road Dogg was suspended in December and eventually released on January 26, 2001, Killings became a singles competitor and became a successful mainstay on Jakked. He took part in the 2001 Royal Rumble, but was eliminated by Big Show. Killings then began competing in the hardcore division. He defeated Raven for the Hardcore Championship on February 3, but lost the title to Crash Holly that same evening under the title's 24/7 rules. He defeated Raven for the title a second time on the following night, but once again he lost the title to Holly within the space of several hours. Killings became somewhat of a background figure of "The Invasion" angle during the summer months, often seen in dressing rooms and watching television with other superstars during inter-promotional matches. Killings was released from the WWF the next year.
