terminated, which led to TNA filing a lawsuit against WWE for contract tampering and eventually firing Flair on May 11. Having been inactive since his September 2011 injury, Flair announced in a December 3, 2012 interview that he would never wrestle again, owing chiefly to an on-air heart attack suffered by age peer Jerry Lawler following a Raw match three months earlier. Return to WWE (2012–2021) On March 31, 2012, while still contracted to TNA as a part of a deal with WWE which allowed Christian Cage to appear at Slammiversary 10, Flair became the first person to be inducted into the WWE Hall of Fame twice, the second time as part of the class of 2012 with The Four Horsemen. On December 17, 2012, Flair returned to WWE as a non-wrestling personality on the annual Slammy Awards show to present the Superstar of the Year award to John Cena, who in turn gave the award to Flair. Flair's return was interrupted by CM Punk and Paul Heyman, escalating into a confrontation that ended with him locking Heyman in the figure-four leglock. After clearing the ring, Flair was assaulted by The Shield (Dean Ambrose, Roman Reigns, and Seth Rollins), until Ryback and Team Hell No (Kane and Daniel Bryan) helped Flair fend off the group. Flair appeared on the main roster sporadically throughout 2013, as The Miz's mentor. He also occasionally appeared on NXT in 2013 and 2014, accompanying his daughter Charlotte to the ring. Flair appeared on April 28, 2014, episode of Raw, alongside the reunited Evolution (minus Flair) and The Shield; Flair showed his endorsement for The Shield, Evolution's opponents at Extreme Rules, effectively turning his back on his old teammates. At Battleground, John Cena symbolically handed over his World Heavyweight Championship belt to Flair, telling him to "take it" while promoting his match. On the post-SummerSlam Raw in August 2015, Flair interrupted Jon Stewart, who had saved Flair's 16 world title record by preventing Cena's victory the previous night, telling him that the record would be broken eventually and he would rather it be by someone who he respects. Flair began making more frequent appearances with Charlotte after she won the Divas Championship. In January 2016, Flair and Charlotte began displaying villainous traits, with Flair often getting involved in Charlotte's Divas Championship and later WWE Women's Championship defenses, thus turning heel for the first time since 2005
