He later joined the then-WWF in 2001, and was assigned to Heartland Wrestling Association, a developmental territory, where he won the HWA Tag Team Championship with Evan Karagias. After debuting on the SmackDown brand, he became a follower of 'Mattitude' and appeared regularly as Matt Hardy's sidekick. Between late 2003 and 2005, Moore was used mainly in WWE's cruiserweight division, until his release in July 2005. After a stint on the independent circuit, Moore joined TNA in December 2005. In March 2006, he re-signed with WWE, initially appearing on the ECW brand, before returning to SmackDown in 2007. He formed a tag team with Jimmy Wang Yang, and the pair challenged unsuccessfully for the WWE Tag Team Championship on several occasions. Following his release in August 2008, he once again returned to the independent circuit, before rejoining TNA in January 2010. He soon formed a tag team, known as Ink Inc., with Jesse Neal in April.
