When we talk about the big names that dominated the boxing rings in their times, there are quite a few names that are popular throughout the world. They are well-known by those without any interest whatsoever in the art of beating your enemies into pulp. Now, each one of these legends had their unique styles and characteristics, with their unique flaws and strengths. However, let it never be said that they lacked class. The hardest punchers in the history of professional boxing are quite renowned, even to this day. In this article, we shall take a bird's eye view of their stints in the professional circuits.
Mike Tyson

"Iron," Mike Tyson is a name that is considered the foremost authority on hard-hitting. In 1986, Tyson revolutionized boxing by adding the element of short and fast moves in order to take the opponent down in a knockout instead of persevering the entire bout of 12 rounds. Carried on the wings of his exceptionally offensive boxing style, he became the youngest ever heavyweight boxing champion in the history of the sport. His style brought a new thrill to the boxing ring, which proved to be quite the siren's call for the crowd who absolutely worshipped his graceful dance in the ring. Despite earning for around $400 million during his career, there was a rumor of being broke and filed a bankruptcy in year 2003. In year 2005, Tyson lost his last fight against Kevin Mcbride.

Joe Louis

Being the boxing sensation of the 1930s and '40s, Joe Louis, holds the division record for holding the heavyweight championship for a continuous period of 140 months (almost 11-and-a-half years) with 26 successful defences of his title. He fought 68 matches and only lost thrice while dishing out 51 knockouts. Louis is hailed as one of the, if not the greatest heavyweight champion in the history of boxing.

Ron Lyle

By never winning a championship title, Ron Lyle is considered to be the epitome of a power puncher. He faced all the big names in the ring and gave them all a tough time. His fight with Mohammad Ali in 1975 carried on well into the 11th round, which is in its self a testament to his humongous will.

Thomas Hearns

Being in the heavyweight category didn't stop the "Hitman" Tommy Hearns from packing a punch right on par the best of them. He was the very first fighter in history to win world titles across four different divisions. His one-punch win against Roberto Duran is considered the most impressive feat in boxing history.

George Foreman

His boxing career spans nearly three decades of power-hitting. Never particularly caring about the finesse part of boxing, he relied on his brute strength to get the job done. George Foreman made his name in the boxing ring as one of the hardest hitters of all time by becoming the first person to defeat the previously invulnerable Joe Frazier in 1973. Foreman's knockout percentage happens to stand at a record 83.9%. After a 21 year break from professional boxing, George Foreman returned to the rings once more with a vengeance and won the title of a heavyweight champion from Michael Moorer.
