Edward Newgate, more commonly known as “Whitebeard”, was the captain of the Whitebeard Pirates and was known as “The Strongest Man in the World”. He was a member of the Yonko that ruled over the New World until his death during the Battle of Marineford.
Whitebeard was given the title of the “strongest man in the world” for his physical power, which is far superior to even a giant.
Despite being old and sick, his physical resistance and pain tolerance were tremendous: he was able to keep fighting despite the number of life-threatening injuries he sustained, which included part of his head being burned off. No matter how much damage he took throughout the battle, Whitebeard continued to press forward and fight, only stopping once almost all of the Blackbeard Pirates collectively shot and brutally stabbed him to death at point-blank range.
He sustained 267 sword wounds, 152 gunshot wounds, and 46 wounds from cannonballs, and got half of his head blasted off, resulting in 465 injuries in total. However, even after taking so much damage in his already weakened state, he died standing, an impressive feat when compared to other characters. Even Teach was shocked by Whitebeard’s tenacity.
2-GOL D. ROGER
Gol D. Roger was a legendary pirate who was known as the Pirate King, captain of the Roger Pirates, and owner of the legendary treasure known as “One Piece”. He was also the lover of Portgas D. Rouge and biological father of Portgas D. Ace.
Roger was hailed as the most powerful pirate of all time. His fighting power was nearly unstoppable. He single-handedly defeated the armies of several countries.
Only two people are known to have ever matched Roger in battle: Vice Admiral Monkey D. Garp and his rival Edward “Whitebeard” Newgate. Roger also possessed immense endurance and vitality even when he was ravaged by an incurable disease. Aided by Crocus’ medical skills, he managed to conquer the Grand Line. He was even able to fight for three days and three nights against Whitebeard until the fight resulted in a draw.
1-MONKEY D. GARP
Garp is one of the most powerful Marines seen in the series so far. As the “Hero of the Marines”, Garp is very well-respected for cornering the Pirate King multiple times.
Despite his advanced age, Garp still posseses tremendous physical strength. He is able to throw iron canonballs like baseballs at speeds higher than if they were fired from an actual cannon, break through brick walls and cannon stands with his fists, and both carry and throw a gigantic ball and chain many times bigger than the Thousand Sunny. Garp also has a monstrous punching power at his disposal, with his epithet, “Garp the Fist”, vouching for the tremendous power of his punches. He claimed to have crushed eight mountains during his training to face Chinjao. Enhanced with Haki, Garp could even dent Chinjao’s Haki enhanced drill-shaped head, which was powerful enough to split the Jewel Ice Sheet.
Even in old age, Garp retained his strength. During the Battle of Marineford, he easily struck down Marco, a Mythical Zoan Devil Fruit User and one of the most powerful members of the Whitebeard Pirates, and in the anime, Garp knocked down Jesus Burgess, a master wrestler with titanic physical strength without effort. In fact, Sengoku had to personally restrain Garp before he attempted to kill Akainu out of fury.
