#3 Sheamus turns face in his feud with Mark Henry in 2011
Sheamus is a brute. An unapologetic brawler that loves to do nothing but beat down those weaker than him. But in 2011, the Celtic Warrior could stand no more after Mark Henry was bullying the Smackdown Live roster. At SummerSlam of that year, Henry defeated Sheamus via a count-out after tackling him through a barricade. That's definitely a good way to give your new found face some momentum, WWE.
Sheamus did, however, pick up quite a few wins afterwards, going on a 14 match winning streak. However, later at WrestleMania that year, the WWE Universe would see one of their favourite stars, Daniel Bryan, lose his World Heavyweight Championship to Sheamus in ten seconds.
Charlotte Flair to return and wrestle a CURRENT CHAMPION?
Moments like that definitely didn't help Sheamus's run as a good guy and after three more years, the newly mohawked brawler finally turned heel again. It took some time for the WWE Universe to get back into Sheamus after four years of bland storytelling from creative, but a tag team with Cesaro allowed Sheamus to prove himself to the fans.
