#3 Becky Lynch becomes The Man - SummerSlam 2018
SummerSlam 2018 was a turning point in Becky Lynch's career. In 2018, Carmella successfully cashed in her Money in the Bank contract to become WWE SmackDown Women's Champion. After winning the title, Carmella lost to both Becky Lynch and Charlotte Flair in non-title matches. So, WWE set up a triple threat match with the title on the line for SummerSlam.
During the match, fans appeared to be rooting for Lynch to win the title. Lynch was about to become SmackDown Women's Champion when she applied the Dis-Arm-Her to Carmella. Then, Flair jumped into the ring and hit Lynch with the Natural Selection.
At the time, Lynch and Flair were best friends. When "The Queen" was declared champion, Lynch hugged her. Then, she knocked Flair to the floor with a punch and launched an attack on her former friend, turning into a more aggressive character.
When Becky Lynch attacked Charlotte Flair "The Man" persona was born. This led the fans to rally around Lynch, and her becoming the eventual face of the WWE.
