#1 Smackdown's Becky Lynch
After winning the six-pack challenge in September 2016, Becky Lynch became the first-ever SmackDown Women's Champion. Lynch's first feud after winning the title was with Alexa Bliss and she eventually dropped the belt to her at TLC after an 84-day reign.
Over the years that followed, Lynch came close to winning the SmackDown Women's Championship on numerous occasions but just missed out each time. Most notably, she earned a shot against then-champion Carmella in a triple threat match and very nearly caused her to tap out, before Charlotte Flair pinned her to win the championship herself.
The events of SummerSlam 2018 triggered a change in Lynch. Following the match, she attacked Fair, igniting an intense rivalry with her former best friend. Lynch began dubbing herself The Man and won the title from Charlotte, before defending against her at Super Shown-Down and again in a Last Woman Standing match at Evolution, a bout highly-praised by fans.
Lynch then dropped the SmackDown Women's Championship to Asuka at TLC following an interference from Ronda Rousey, who pushed both her and Charlotte Flair off a ladder. Her second reign with the championship ended at 91 days.
In the build-up to WrestleMania 35, The Man was involved in a rivalry with both Rousey and Charlotte. A triple threat, winner-takes-all match was set for the three of them in the first-ever women's main event at WrestleMania.
Lynch won both the RAW and SmackDown Women's Championships by pinning Rousey, a historic moment in WWE history. Lynch's third reign as SmackDown Women's Champion ended after 41 days after Lacey Evans interfered at Money in the Bank to help Flair win back the title.
