At Bound for Glory, Hardy turned heel with Hulk Hogan and Eric Bischoff and with their help defeated Angle and Anderson to win the TNA World Heavyweight Championship for the first time. They were then joined by Jeff Jarrett and Abyss, revealing the group that Abyss had been referring to as "they" for several months. On the following episode of "Impact!", the stable was named Immortal, as it formed an alliance with Ric Flair's Fortune. Meanwhile, Hardy debuted a new dark character, using cryptic messages as he explained the reasons behind his turn. At Turning Point, Hardy retained his title in a defense against Matt Morgan, a replacement for Mr. Anderson, who was sidelined after suffering a concussion during an attack by Hardy. On the following episode of "Impact!", Hogan presented Hardy with a new design of the TNA World Heavyweight Championship, which he dubbed the TNA Immortal Championship. At Final Resolution in December, Hardy successfully defended the championship in a rematch against Morgan after incapacitating the special guest referee Mr. Anderson and having a replacement referee count the pinfall. On January 4, 2011, Hardy made his debut for New Japan Pro Wrestling (NJPW) at Wrestle Kingdom V in Tokyo Dome, where he successfully defended the TNA World Heavyweight Championship against Tetsuya Naito.
