Karol Rosa

• Age: 31
• Country: Brazil (Vila Velha)
• Fighting Style: Muay Thai
• UFC Record: 19–7–0
• Reach: 67.5 in, Height: 65 in

A seasoned vet on the world stage since 2019, Rosa is known for her crisp leg kicks, forward pressure and high-volume striking. Her 56% significant strike accuracy pairs with a 50% defense rate—she lands more than half her power shots but remains susceptible to counter-strikes. Rosa’s takedown accuracy (48%) and defense (70%) show she can mix in wrestling, but she typically prefers to keep the fight upright.

Luana Santos

• Age: 26
• Country: Brazil
• Fighting Style: Judo
• UFC Record: 10–2–0
• Reach: 67 in, Height: 66 in

A fast-rising grappler, Santos debuted in 2023 and quickly established herself as a submission threat, boasting five career wins by tapout. Her takedown defense (86%) ranks among the division’s best, and she counters strikes with high-level clinch work. While she lands 53% of her significant strikes—nearly matching Rosa’s accuracy—she averages fewer total strikes per minute and must rely on wrestling exchanges to assert dominance.
