Mercedes Mone has made fans go berserk online after achieving a major milestone in AEW.Mercedes Mone is arguably one of the most bankable stars in AEW, not just in the company's women's division. The CEO, who debuted in the Jacksonville-based promotion in March 2024, quickly made an impact and, within a few months at Double or Nothing in May, captured the TBS title, which she has held ever since.
