This article will explore the journey of Alex Pereira, his achievements in kickboxing, his transition to MMA, and what makes him a threat inside the Octagon.
Early Life and Background
Born on July 7, 1987, in São Bernardo do Campo, Brazil, Alex Pereira’s early life didn’t initially hint at the greatness he would one day achieve in combat sports. Like many fighters, he came from humble beginnings and faced various challenges growing up. He was drawn to sports at an early age but initially began training in basketball before discovering his true passion—fighting.
At 12 years old, Pereira shifted his focus to kickboxing. He quickly realized that his natural athleticism, combined with a fierce competitive streak, made him a standout in the striking arts. Under the guidance of his trainers, he honed his skills in kickboxing and began to make a name for himself in Brazilian fighting circles.
Kickboxing Career: The Making of a Champion

Alex Pereira’s kickboxing career was nothing short of extraordinary. He made a name for himself in the sport thanks to his exceptional knockout power, precision, and ability to dismantle opponents with his striking technique. Pereira fought in numerous organizations, but it was his time in Glory Kickboxing where he truly made his mark.
In 2015, Pereira won the Glory Middleweight Championship, showcasing his world-class striking and tactical mastery. His victory cemented his place as one of the top kickboxers of his generation. But it wasn’t just his titles that made him famous—it was his ability to knockout opponents in spectacular fashion, often in the most dramatic ways.
His greatest claim to fame in kickboxing came when he defeated Israel Adesanya, the future UFC Middleweight Champion, in 2017. Pereira and Adesanya had fought twice in kickboxing, with Pereira winning both matchups, including a knockout victory in the second fight. This victory over Adesanya added to Pereira’s growing legend as a knockout artist and a true force in the sport.
Transition to Mixed Martial Arts
After dominating in kickboxing, Alex Pereira transitioned to MMA in 2015, although he continued his kickboxing career for several years. His decision to switch to mixed martial arts was strategic, as he wanted to prove himself in the world of MMA and take on a broader range of challenges.
Pereira made his MMA debut in 2015 under the Brazilian Fighting Championship (BFC). Despite being relatively new to the sport, his striking ability quickly stood out, and it wasn’t long before he attracted attention from major MMA organizations. His transition to MMA was not without challenges, as he had to adapt to the grappling and wrestling elements of the sport. However, Pereira’s elite striking remained his bread and butter, and he soon became a formidable competitor.
By 2021, after a series of wins in smaller MMA promotions, Pereira’s talent caught the attention of the UFC, the world’s most prestigious MMA organization. The UFC saw something special in him—not just his knockout power, but his potential to be a major draw due to his rivalry with Israel Adesanya.
Alex Pereira in the UFC
Pereira’s debut in the UFC was highly anticipated due to his previous kickboxing history with Israel Adesanya. The MMA world was buzzing to see whether Pereira could carry over his striking dominance into the Octagon and succeed in UFC’s elite competition.
In his UFC debut, Pereira faced André Muniz at UFC 268. Although he won, it wasn’t until his second fight that he truly made an impact. At UFC 268, Pereira faced Sean Strickland and made an immediate statement by knocking him out in the first round. This stunning victory propelled Pereira into the spotlight and confirmed that he was ready for the UFC’s biggest stage.

In their UFC encounter, Pereira shocked the MMA world by knocking out Adesanya in the fifth round, claiming the UFC Middleweight Championship. This victory was monumental, as Pereira had now defeated Adesanya in all three of their encounters—two times in kickboxing and once in MMA.
