5 most brutal Alex Pereira knockouts outside the UFC

#2. Alex Pereira vs. Ertugrul Bayrak

Just three months after his sensational knockout victory over Donegi Abena to win the GLORY interim light heavyweight strap to become a double champion, Alex Pereira headed back down to middleweight for one last title defense. At GLORY Collision 2, the Brazilian knockout artist locked horns with Ertugrul Bayrak.

Pereira thoroughly outclassed Ertugrul Bayrak for as long as this bout lasted. The challenger struggled against the middleweight champion's reach and pressure, and as each second passed, it felt as though a signature 'Po Atan' knockout was inevitable.

At the three-minute mark, Pereira uncorked a monstrous left hook which sent Bayrak flying into the ropes and then onto the ground. This remains the Brazilian powerhouse's last knockout in the kickboxing ring.

#1. Alex Pereira vs. Thomas Powell – His last fight before joining the UFC

Alex Pereira's last appearance in the kickboxing ring came at GLORY 78 in the Netherlands, where he came out on the losing end of a majority decision to Artem Vakhitov. At the time, the Brazilian's MMA record stood at 2-1, and he opted to fully commit to the sport.

Just two months after his loss to Vakhitov, Pereira featured in an LFA bout against Thomas Powell and the fight was even broadcast on UFC Fight Pass.

Alex Pereira made light of Thomas Powell on the night, finishing the American with a thunderous left hook, his most lethal weapon. Powell was reportedly unconscious for several minutes, much like Pereira's victims in the kickboxing ring.
