Mike Tyson’s early career is legendary, defined by his reputation as one of the most powerful knockout artists in boxing history. In the first 19 fights of his career, Tyson left an unforgettable mark, knocking out every single opponent he faced. Perhaps even more astonishing, 12 of those knockouts happened in the very first round, earning Tyson the title of “The First-Round Destroyer.”

Tyson, at the young age of 18, stepped into the ring with a determination and ferocity rarely seen in the sport. Under the guidance of trainer Cus D’Amato, Tyson quickly developed a style that combined raw power with exceptional speed and precision. D’Amato’s “peek-a-boo” boxing technique allowed Tyson to get in close to his opponents, dodging punches and setting himself up for powerful counterattacks.

From his very first professional bout in 1985 against Hector Mercedes, Tyson made his intentions clear. That first fight ended with Mercedes on the canvas, a scene that would become all too familiar as Tyson blazed his way through the heavyweight ranks. Opponents simply couldn’t withstand the strength and intensity of his punches, often falling within minutes of the first bell.

Tyson’s ability to dominate early in the fight is still a marvel. Of his first 19 matches, 12 opponents didn’t even make it to the second round. Here’s a look at some of these incredible first-round finishes:

1. **Trent Singleton** – Tyson faced Singleton in his second professional fight and secured a first-round knockout, announcing his arrival as a force to be reckoned with.
   2. **Ricardo Spain** – Spain didn’t last long, as Tyson’s aggressive approach overwhelmed him, ending in yet another quick knockout.
   3. **Donnie Long** – By the time Tyson faced Long, he was already gaining a reputation for his destructive punching power, finishing this fight in the first round.
   4. **Robert Colay** – Tyson’s knockout streak continued as he bulldozed Colay, adding to his first-round KO tally.
   5. **Sterling Benjamin** – With another crushing first-round finish, Tyson continued proving his unmatched speed and power.
   6. **Sammy Scaff** – Scaff entered the ring as a tall, powerful opponent, but Tyson’s unmatched skill quickly brought him down in the first round.
   7. **Mark Young** – Another victim of Tyson’s brutal first-round onslaught, Young had no answer for Tyson’s relentless attacks.
   8. **John Alderson** – Alderson found himself overpowered within minutes, as Tyson sealed the fight with another quick knockout.
   9. **Michael Johnson** – Johnson fell victim to Tyson’s unyielding power, marking yet another first-round triumph.
   10. **Lorenzo Boyd** – By the time Tyson reached Boyd, his reputation had spread; Boyd succumbed in the first round as well.
   11. **Marvis Frazier** – Son of heavyweight legend Joe Frazier, Marvis tried to go the distance but lasted only 30 seconds against Tyson.
   12. **Carl Williams** – Williams was Tyson’s 12th first-round knockout, cementing Tyson’s status as the most dominant heavyweight of his time.
