#3. AJ Styles was a fan favorite for the WWE Universe in his feud against John Cena
AJ Styles' heel turn in WWE was absolutely perfect. WWE totally nailed it in terms of creative direction when they turned The Phenomenal One into a bad guy for the first time since his arrival in the company.
Upon John Cena's return to the WWE, he made his intentions clear and claimed that the "new generation" would have to go through him. Up stepped AJ Styles and what initially felt like a babyface vs. babyface feud, quickly saw the former IWGP Heavyweight Champion hit Cena with a clothesline and establish himself as a heel.
With both Luke Gallows and Karl Anderson by his side, Styles quickly became an anti-hero in the eyes of the WWE Universe. During his matches against Cena at Money in the Bank and SummerSlam, Styles was cheered on by the WWE Universe despite being the heel.
It's no secret how the WWE Universe has always reacted towards Cena, but to have them cheer for a Superstar who was still quite fresh in the company against someone of Cena's magnitude was a big statement.
