When she goes to the gym now, it's filled with female fighters.

"That's the proudest legacy I could leave behind," Taylor said. "Just to inspire the next generation."

Serrano, 36, a champion in a women's-record seven weight classes, and who remains the featherweight champion, has already begun what will be her transition to a post-fighting career. MVP's first signee later inked a lifetime contract with the organization, founded by Paul and Nakisa Bidarian, to become its chairwoman of boxing initiatives, and will be responsible for identifying, signing and marketing the roster of women's athletes.

But, she can't stop fighting yet. Not when all the massive paydays that eluded her for most of her career have started rolling in.

And not when there's still a chance to finally notch a victory over Taylor.

"It means a lot more this time, with it being an all-woman card," Serrano said. "Having the opportunity to fight Katie Taylor once again is amazing. The payday is truly amazing, but, to share this card with all these incredible women is the highlight of the night, I think.

"Listen, the opportunity presented itself, and I think it is just a great ending to the story — especially my story — when I finally win."
