In 2018, Becky Lynch transitioned towards a more aggressive character, which started at SummerSlam when she attacked Charlotte Flair, perceiving herself as an unfairly-treated underdog and dubbing herself "The Man", resulting in a large increase in her popularity and fan support.
In January 2019, she won the Women's Royal Rumble match. On 7 April, at WrestleMania 35, in what was the first time women headlined a WrestleMania event, Lynch won both the Raw Women's Championship and SmackDown Women's Championship in a Winner takes all match against Ronda Rousey and Charlotte Flair, making her a double champion and the only woman to hold both titles simultaneously.
Lynch is now an overall four-time women's champion in WWE. During a recent interview with Sports Illustrated, the Irish superstar recalled WrestleMania 35 main event: “Wrestling is 20% about the matches and 80% about how you engage with the people who care about you.
I remember walking through the building at WrestleMania 35, passing by The Undertaker and Hulk Hogan. I’d idolized them when I was younger, and now they’d be watching me in the main event. And that’s something I accomplished with the help of these people.
There’s probably some Buddhist lesson on how you’re supposed to savor the moment or how you’re not supposed to keep looking forward, but that’s the industry we’re in. There is so much competition and you have to stand out.
If you don’t, you’ll be left behind. I’m constantly thinking about the work at hand. How do I make this more interesting? Do I need to be more of an antagonist? How do I get the most of this match? There’s no time to celebrate. I’m already onto the next goal and putting in the work”.
