She made her AEW debut last year and is already one of the top stars in the company.Speaking on the Marking Out podcast recently, Mercedes explained the difference between the AEW and WWE locker rooms.“For me, it’s night and day. When I am around the girls, it just feels like such a community of wanting to make this place grow. There's a hunger because I feel like we still feel so underground, and we want to make it, like, up here. So all these women have so much drive and passion, and I can feel it. [...] It feels so different. I don't want to say like, ‘Oh, WWE was bad’ or people are like, egos, but it just feels like we're all trying to fight for something," Mone said.It will be interesting to see if The CEO manages to retain her TBS Title at Forbidden Door 2025.
