how strong was gol d roger

Gol D. Roger was extraordinarily strong, regarded as the strongest pirate in the One Piece world. He had no Devil Fruit powers but possessed overwhelming physical strength, advanced mastery of all three types of Haki—Observation, Armament, and the rare Supreme King Haki—and incredible swordsmanship with one of the 12 Supreme Grade swords. Roger could infuse his Haki into his attacks, creating devastating shockwaves that rivaled the power of other legendary figures like Whitebeard. He was able to defeat tough opponents such as Kouzuki Oden with a single strike and fought intense battles lasting days, including a famous three-day clash with Whitebeard. Despite battling an incurable disease toward the end of his life, he conquered the Grand Line in just three years. Roger was also rare in his ability to hear the "Voice of All Things," communicate with the giant elephant Zunesha, and unite his crew under his strong will and pursuit of freedom. His bounty of over 5.6 billion berries remains the highest in history, symbolizing his unmatched strength and legacy as the Pirate King.
