Karine Silva Bio
Karine Silva de Almeida, born on December 2, 1993, is a Brazilian professional mixed martial artist competing in the women’s Flyweight division of the Ultimate Fighting Championship (UFC). Known by her ring name “Killer,” she has steadily built a reputation as a submission specialist and ranked contender within the organization. As of September 9, 2025, she holds the #9 position in the UFC women’s flyweight rankings, reflecting years of disciplined work across regional and international circuits. She currently trains with the Fighting Nerds team out of Curitiba, Paraná, Brazil.
Early Life and Background
Karine Silva de Almeida was born in Dourados, Mato Grosso do Sul, Brazil, and grew up facing limited financial resources. To chase her dream of competing in martial arts, she made the bold decision to leave her job and move into a martial arts academy, even without moral or financial backing from her family. To make ends meet while training, she worked a series of odd jobs, including roles as a security guard, masseuse, and receptionist. Her early introduction to combat sports came through “Chinese boxing,” a striking discipline that laid the foundation for her eventual transition into mixed martial arts.
At the age of 19, she made her professional MMA debut, though the path was never fully planned from the start. Driven by an unexpected passion for the sport, she chose to leave school, distance herself from family, and dedicate herself entirely to training. This commitment led her to join a team that exposed her to a wide range of disciplines, including luta livre, wrestling, mixed martial arts, and muay Thai, shaping her well-rounded skill set.
Path to MMA
Silva’s professional career began in 2013, and she quickly established herself in the Brazilian regional scene. The bulk of her early career played out on home soil, where she became a dominant figure under the Aspera Fighting Championship banner. She captured six wins in the organization, including a first-round armbar headlining performance against Leticia Oliveira Ribeiro at AFC 20. Her only setback in those formative years came against fellow future UFC fighter Maryna Moroz at XFC International 7 on November 1, 2014, when she was submitted via armbar in the first round.
Following the Moroz loss, Silva strung together four consecutive stoppage wins and briefly ventured abroad for an international debut at Fight Nights Global 81 in December 2017, where Marina Mokhnatkina caught her with a kneebar. After a two-year layoff, she returned at flyweight and began a five-fight winning streak that ultimately earned her a shot at the UFC. That opportunity arrived on Dana White’s Contender Series 45 against Qihui Yan, where she reversed a difficult first round with a second-round guillotine choke at 1:44 to secure her contract.
Karine Silva Career
Early Career (2013-2021)
Silva’s early career was defined by a mix of regional dominance and hard lessons abroad. Outside of a brief and ultimately unsuccessful stint in Russia, she built her record primarily in Brazil, racking up stoppage wins and establishing herself as a finisher. Her ability to adapt across weight classes, including a return to flyweight, helped her regain momentum after a two-year break and an earlier unanimous decision loss to Dione Barbosa. The knockout of Vitoria Ferreira in August 2019 marked the beginning of the five-fight winning streak that carried her to the UFC doorstep.
UFC Breakthrough (2022-2023)
Silva made her UFC debut on June 4, 2022, at UFC Fight Night 207 against Poliana Botelho and won via brabo choke in the first round, earning a Performance of the Night award in the process. In her sophomore outing on June 3, 2023, at UFC on ESPN 46, she extended her winning run with a first-round kneebar submission over former Invicta champion Ketlen Souza. She then avenged one of her earliest career losses by rematching Maryna Moroz at UFC 292 on August 19, 2023, and finished the fight with a first-round guillotine choke.
Fighting Nerds Era (2024-2025)
On April 27, 2024, at UFC on ESPN 55, Silva faced Ariane Lipski and earned a unanimous decision victory, showcasing her evolving ability to grind out wins when finishes are not available. Her momentum was briefly checked on November 16, 2024, at UFC 309, where she dropped a unanimous decision to Viviane Araújo. She returned to the win column on August 16, 2025, at UFC 319, where she took a unanimous decision over Dione Barbosa after original opponent JJ Aldrich withdrew. Silva is scheduled to face Maycee Barber on December 6, 2025, at UFC 323, as she continues to press her case inside the UFC women’s flyweight top ten.
Driving Style and Strengths
Silva fights from an orthodox stance and is widely regarded for her submission grappling, with multiple career wins coming by guillotine choke, brabo choke, and kneebar. She is a black belt in Brazilian Jiu-Jitsu, and her ground game pairs with an aggressive, opportunistic striking approach that allows her to capitalize on opponents’ mistakes. Standing at 163 cm with a 170 cm reach, she uses her length effectively to set up clinches and transitions, fitting well with the Fighting Nerds’ balanced training environment.
Notable Events and Milestones
One of the defining moments of her career came on Dana White’s Contender Series 45, where her second-round guillotine choke of Qihui Yan earned her a UFC contract. Her Performance of the Night bonus in her UFC debut against Poliana Botelho signaled her immediate impact on the global stage. By September 2025, she had climbed to #9 in the UFC women’s flyweight rankings, cementing her status as a rising contender in the division.

Family Background and Racing Lineage
Publicly available information about Karine Silva de Almeida’s parents and immediate family remains limited. She has spoken about taking her early leap into martial arts without the moral or financial support of her family, choosing instead to support herself through a series of odd jobs. That period of independence shaped her disciplined approach to training and competition, and her family background has otherwise been kept private.
Personal Life
Silva currently resides in Curitiba, Paraná, Brazil, where she trains with the Fighting Nerds team. Detailed information about her spouse, children, or marital status has not been publicly confirmed in verified sources. Her personal narrative, built around perseverance and self-reliance, remains a central part of her public identity.
2025 Season Performance
The 2025 season has been a defining year for Karine Silva de Almeida inside the UFC women’s flyweight division. After dropping a unanimous decision to Viviane Araújo at UFC 309 in November 2024, she returned to the win column with a unanimous decision over Dione Barbosa at UFC 319 on August 16, 2025. That victory, originally booked against JJ Aldrich before a late opponent change, kept her inside the divisional top ten and reinforced her position as an active contender.
Her ranking of #9 as of September 9, 2025, reflects the consistency she has shown since debuting in the promotion. With the Fighting Nerds team providing her training base in Curitiba, she continues to develop her well-rounded game, balancing grappling pressure with improved striking output. The booking against Maycee Barber at UFC 323 on December 6, 2025, represents a high-profile opportunity to push deeper into title contention before the calendar turns.
Looking ahead, a win over Barber would mark her most significant statement to date and could position her for a potential top-five matchup in 2026. Even in defeat, her activity and willingness to face ranked opposition suggest she will remain a fixture in the flyweight conversation. The 2025 campaign, in short, is shaping up as the platform from which her next career phase will be built.
