3-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.
2-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.
1-ROCKS D. XEBEC
Although Rocks’ individual strength and abilities are unknown, he was well-reputed for presiding over a crew of extremely powerful pirates with clashing personalities and a lack of camaraderie, indicating that he was an extremely powerful and charismatic individual and possibly the strongest person of his time.
Many of these people would go on to make big names for themselves; Edward Newgate, Charlotte Linlin, and Kaido even became Emperors of the New World.
Xebec was considered to be the most formidable rival of the Pirate King, Gol D. Roger, even more so than his then-subordinate Whitebeard would come to be. He was so fearsome, it took both Roger and Monkey D. Garp working together to finally defeat him.
