One Piece: Is Luffy As Strong As Gol D. Roger And Whitebeard?

gamerant.com:

Monkey. D Luffy is the protagonist of Eiichiro Oda's One Piece and he aims to become the King of the Pirates in a time known as the Great Pirate Era. In a plethora of pirates, Luffy aims to rise to the very top and become the freest man on the oceans. With his pirate crew, known as the Straw Hat Pirates, Luffy has, over the years, gained plenty of notoriety and made an incredible name for himself as well. His strength has gradually grown and, after the two-year timeskip, he's become tremendously powerful. In the Wano Country arc, he took the next big step on the big stage when he faced off against Yonko Kaido in a serious battle and gave him a run for his money. #

By the end of the fight, Luffy ended up gaining new powers that pushed him on level with Kaido and, eventually, even crush him in battle. With Kaido's defeat, he's now established himself as one of the very strongest characters in the world of One Piece and can now inevitably draw comparisons to the legends of the world, such as Whitebeard and Gol D. Roger, however, is he that powerful?

Although Luffy was nowhere near the level of the legends of the One Piece world when the story began, he has grown at a staggering rate and has evolved into an extremely refined fighter. Having eaten the Gomu Gomu no Mi, Luffy has gained the power of rubber and while that in itself isn't all that amazing, the way he utilizes this power certainly makes it quite incredible. Luffy has the power of Gears, which he created during the Enies Lobby arc for the very first time.

With Gear Second, Luffy can dope himself by pumping blood faster through his body, and using Gear Third, he can inflate his bones to gain the limbs of a giant.
