Cris Cyborg, a titan in mixed martial arts with a remarkable 21-year career, identifies her proudest moment as the 2009 victory against Gina Carano for the Strikeforce featherweight title. This historic fight not only marked the first women's title bout to headline a major event but was also broadcast live on primetime television in the U.S.

The bout was groundbreaking, featuring the first-ever five, five-minute rounds in women's MMA, setting a new standard for the sport. At 41, Cyborg reflects on this achievement as pivotal, stating it opened doors not only for her but for countless other women in MMA.

Cyborg emphasized the significance of that fight, saying, "I believe a lot of people over the world watched that fight and it opened a lot of doors. We were training hard saying one day the opportunity is going to come and we're going to be ready to show that girls can fight."

Her performance that night was nothing short of spectacular, finishing the fight with only one second remaining in the first round, which redefined her image from Cris Cyborg to "the killing machine."

Since then, Cyborg has accumulated an impressive record, winning 21 of her last 22 fights and securing titles in organizations like the UFC, Bellator, and PFL.

As she prepares to defend her PFL featherweight title against Ketlen Vieira in Tampa, Florida, this match could signal the end of her illustrious career, marking the conclusion of her "legacy tour." Cyborg remains tight-lipped about her future plans, leaving fans eager to see what comes next.
