Hardy debuted in Total Nonstop Action Wrestling on June 23, 2004 at the TNA weekly pay-per-view #100, the Second Anniversary Show, in a match against TNA X Division Champion A.J. Styles, for the title. He also debuted his new entrance theme "Modest", a song performed by Hardy himself, and his new nickname "The Charismatic Enigma". The match ended in a no-contest when Kid Kash and Dallas interfered. Hardy returned to TNA on July 21 and was awarded a shot at the NWA World Heavyweight Championship. Hardy challenged for the title on September 8, losing to NWA World Heavyweight Champion Jeff Jarrett. In October 2004, he won a tournament, earning a shot at the NWA World Heavyweight Championship on November 7 at Victory Road. Hardy was defeated by Jarrett once again in a ladder match at Victory Road following interference from Kevin Nash and Scott Hall. One month later at Turning Point, Hardy, A.J. Styles and Randy Savage defeated Jarrett, Hall and Nash (collectively known as the Kings of Wrestling). Hardy went on to defeat Hall in a singles match, substituting for Hector Garza at Final Resolution on January 16, 2005.
