#3 – Monkey D. Garp
Garp is one of the most powerful characters seen in the series so far. Alongside Roger, he fought and prevailed against the very powerful Rocks Pirates led by the most dangerous and strongest pirate of their time Rocks D. Xebec, earning him the epithet of “Hero of the Marines”.
He is known for cornering and fighting Gol D. Roger many times. Roger also stated that he and Garp had almost killed each other on numerous occasions. As another true testament of sheer power, Garp defeated and nearly killed Don Chinjao in the past with a single punch, whose bounty was worth over 500,000,000 Berries in his prime and was said to be able to split a continent with a headbutt.
The extent of Garp’s power and fame is evident round the time of the Battle of Edd War, three years before the future Pirate King died. It was revealed that he was offered the promotion to the rank of admiral more than once, but repeatedly refused the promotion.
Despite his advanced age, Garp still posseses tremendous strength.
