#2 AJ Styles: 2016 - 2017

The wrestling world was shocked in 2016 when Mr TNA, AJ Styles finally joined WWE. Naturally, AJ debuted to a monster pop and has been every bit as incredibly popular ever since.
Just after his feud with Chris Jericho, culminating at WrestleMania 32, AJ would feud with Roman Reigns for the WWE Championship. AJ wasn't officially a heel for this feud but did show some heel signs, but despite this, AJ was cheered far more than the Champion (partially because he was facing Reigns).
Following the conclusion, Styles would feud with John Cena, this time officially turning heel, but it was really hard to tell. I mean sure, Cena received his usual back and forth response from the fans, but Styles was cheered a lot during all their matches.
'The Phenomenal One" then feuded with the very popular Dean Ambrose for the remainder of the year but was also cheered over him. AJ remained a heel coming in to 2017, where following his WWE Championship loss, he would feud with popular SmackDown commissionaire Shane McMahon and was still cheered.
Finally, WWE gave up on AJ as a heel and officially turned him face again as he feuded with Kevin Owens. The only constant during AJ's heel run, was the deafening chants of ''AJ Styles, AJ Styles, AJ Styles''.
