Let’s start with one of Pereira’s most iconic knockouts, which would eventually lead to a long-running rivalry in the UFC. Alex Pereira faced Israel Adesanya in a kickboxing match at GLORY 15: Istanbul in 2017.

Pereira already had the reputation of being a brutal knockout artist, but this fight would prove it beyond a shadow of a doubt. Adesanya, at that time, was still considered a rising star in the kickboxing world, but Pereira was simply on another level that night.

In round 3, with the fight hanging in the balance, Pereira caught Adesanya with a devastating left hook. Adesanya, who was leading on points and controlling much of the fight, was stunned by the punch and immediately dropped to the canvas.

The knockout was vicious and clean, instantly silencing the crowd. It was a moment that would not only haunt Adesanya’s career but also set up their UFC clash years later—with Pereira now owning the mental edge over his rival.

 Knockout of Yousri Belgaroui – GLORY 42: Paris (2017)

Another standout knockout came at GLORY 42: Paris, where Pereira faced the tough and durable Yousri Belgaroui. Both fighters were known for their knockout power, and this bout was expected to deliver fireworks.

However, it was Pereira’s left hook that once again proved to be his most lethal weapon. In round 2, Pereira launched a devastating left hook to Belgaroui’s head after a series of exchanges, and just like that, Belgaroui was sent crashing to the mat in a heap.

The knockout was textbook Pereira—sharp, calculated, and explosive, showcasing just how dangerous he could be even against a fighter with a solid chin.

 Knockout of Benoit “The Godfather” Hamon – GLORY 48: New York (2018)

In 2018, Pereira faced Benoit Hamon at GLORY 48 in New York, and once again, Pereira delivered a brutal knockout that shocked the kickboxing world.

In the third round, Pereira uncorked a huge knee to the head of Hamon, which left his opponent unconscious before he even hit the canvas. The knee came out of nowhere, as Pereira was known for setting up his punches and kicks with slick combinations—but this knee was perfectly timed and perfectly placed.

This finish marked another example of Pereira’s versatility and why he was considered one of the best in kickboxing.

 Knockout of James McSweeney – GLORY 44: Chicago (2017)

Next up is a more brutal and explosive finish, one that shows Pereira’s power when he’s truly looking to end a fight quickly. In GLORY 44: Chicago, Pereira squared off against James McSweeney, a big name in the light heavyweight kickboxing scene.

After some back-and-forth action, Pereira managed to land a devastating right hook to McSweeney’s jaw. The punch sent McSweeney crashing to the mat in dramatic fashion, leaving the crowd in complete disbelief. Pereira’s ability to close the distance and land a fight-ending shot was on full display in this knockout, reminding everyone just how dangerous he was.

 Knockout of Michael Duut – GLORY 37: Los Angeles (2016)

This knockout, although not as famous as the Adesanya finish, was another spectacular display of Pereira’s knockout artistry. Against Michael Duut, Pereira showed why he was quickly rising to prominence in the kickboxing world.

Pereira was patient and precise in his attack, but in round 2, he uncorked a devastating left hook-right hook combination that dropped Duut to the canvas. It wasn’t just the power of the punches that made this knockout brutal, but the perfect timing and fluid combination, which Pereira executed like a seasoned pro.

This finish added to his growing reputation as a fighter who could finish anyone, anywhere, at any time.

 Knockout of Dustin Jacoby – GLORY 26: Amsterdam (2015)

Before making his name in the UFC, Pereira was already turning heads in kickboxing, and one of the first fighters he caught in his devastating storm was Dustin Jacoby.

At GLORY 26 in Amsterdam, Pereira went toe-to-toe with the American fighter, and as the fight wore on, it was clear that Jacoby was in trouble. In the third round, Pereira threw a perfectly placed hook-knee combination, catching Jacoby with the knee and sending him to the canvas in a heap.

The knockout was brutal, as Jacoby simply couldn’t react in time to avoid the devastating knee, showcasing Pereira’s ability to finish fights with unorthodox strikes.

 Knockout of Anderson “Braddock” Silva – GLORY 17: Los Angeles (2014)

In one of his earlier career highlights, Pereira faced Brazilian fighter Anderson “Braddock” Silva at GLORY 17. The bout ended in the first round, when Pereira landed a devastating flying knee that knocked Silva out cold.

The flying knee is one of Pereira’s signature moves, and in this particular instance, it was executed with surgical precision. Silva never saw the knee coming, and when it landed, it was lights out. This knockout was a clear indication that Pereira wasn’t just a striker; he was a complete and unpredictable fighter, capable of pulling out devastating finishes at any moment.

 Knockout of Rico Verhoeven – GLORY 28: Paris (2015)

In what many considered an upset, Pereira faced the reigning GLORY Heavyweight Champion, Rico Verhoeven. Though Pereira didn’t secure a knockout in this fight, his ability to outbox and land multiple damaging strikes against one of the sport’s best is a testament to his growing abilities.
