Brock Lesnar shocked the world by defeating one of the most celebrated and successful UFC heavyweight champions of his era, Randy Couture. It took only four fights into his mixed martial arts career for 'The Beast Incarnate' to become UFC heavyweight champion.

Brock Lesnar was the most dangerous man in MMA when he stopped three-time UFC heavyweight title-holder Randy Couture at UFC 91 in less than 10 minutes.

When the fight started, it looked as if Randy Couture was on his way to getting another brilliant win. However, Brock Lesnar, who had a roughly 50-pound weight advantage over the 45-year-old MMA veteran, proved his mettle to the world.

Brock Lesnar took down the defending champion in the first round with a clean double-leg. The defending champion fought smarter, scored reversals and punched cleaner. However, it was only a matter of time before Lesnar got into his groove with hard knees and tooth-shattering strikes.

Early in the second round, Brock Lesnar connected with a short but massive elbow, wobbling Randy Couture. The UFC legend retaliated with a right overhand that cut Lesnar's eye, but the newcomer's relentless power was too much to deal with.

As Couture dropped to the mat after a straight right from Brock Lesnar, referee Mario Yamasaki gave the defending champion a good deal of time to recover. But then came the scary hammer-fists from Lesnar, who forced a stoppage at 3:07 in round two. Couture attributed his loss to Lesnar's size and said:

"I felt good. He (Brock Lesnar) is just a big guy. He caught me with a big shot."

#3. Brock Lesnar avenges his loss against rival Frank Mir

Brock Lesnar's first loss in MMA came during his UFC debut against Frank Mir via a first-round submission. After bouncing back with two back-to-back wins and grabbing hold of the UFC heavyweight title, Lesnar faced Frank Mir in a rematch at UFC 100 in 2009.

A lot of bad blood had developed between the two fighters since their first face-off. While the animosity was evident in the build-up to the rematch, Brock Lesnar made his feelings known when he refused to touch gloves with Mir. The fight started with Lesnar throwing some leg kicks Mir's way before taking him down.

Brock Lesnar fell to a kneebar against Frank Mir at UFC 81, so when Mir tried to grab a hold of his leg during the rematch, Lesnar sprawled and transitioned to half-mount. He grabbed Mir's neck and started landing heavy, punishing strikes on his face and body.

All of the first round saw Brock Lesnar damage Mir. 'The Beast Incarnate' started round two with a clean double-leg takedown but then got back up, inviting Mir to a stand up. However, as Mir landed a left-hook and a couple of knees, Lesnar took him down again and pinned him just like he did in round one.

Frank Mir had no way to escape the size and strength of Brock Lesnar, who was hell-bent on delivering pain to his bitter rival. Lesnar eventually trapped Mir's left arm and started caving his face in with power-shots, forcing a stoppage.

He stood up as the undisputed UFC heavyweight champion, and shouted at the buzzing arena:

"Who is the f***ing man?"
