On January 9 at Genesis, Hardy's brother, Matt, made his TNA debut as a surprise member of Immortal and defeated Rob Van Dam to prevent him from receiving a match at Hardy's championship. That same night, Hardy gave Anderson a match for the TNA World Heavyweight Championship, immediately following Anderson's victory in a number one contender's match. Despite Matt, Flair, and Bischoff interfering in an attempt to help Hardy, Anderson defeated Hardy for the championship. On the January 13 episode of "Impact!", the Hardy Boyz reunited and defeated Anderson and Van Dam in a tag team match, following interference from Beer Money, Inc. On the February 3 episode of "Impact!", Hardy received his rematch for the TNA World Heavyweight Championship. The rest of Immortal interfered in the match, but were stopped by Fortune, which led to Anderson retaining the championship. On February 13 at Against All Odds, Hardy defeated Anderson in a ladder match to regain the TNA World Heavyweight Championship. Hardy held the championship for less than two weeks, defending it once against Rob Van Dam, before losing it to the returning Sting on February 24, at the tapings of the March 3 episode of "Impact!". On March 13 at Victory Road, Hardy received a rematch for the title under No Disqualification rules, but was defeated in ninety seconds. TNA had made the decision to cut the match short after deeming that Hardy was too intoxicated to wrestle. The following day it was reported that TNA had sent Hardy home from the week's "Impact!" tapings. On the March 17 episode of "Impact!", Immortal severed their ties with Hardy.
