It is a known fact that Kaido has lost to his fellow Yonko and the Navy a combined 7 times and been captured a total of 18 times. While Kaido might be the strongest in terms of raw strength, there are definitely those who can beat him a fight. Write for Us!
In this formidable show of strength, we are at least made known that he was defeated 7 times, and captured by the marines a couple of times as well.
According to Kaido, so far, only 5 people can fight equally against him besides Luffy and Big Mom, they are Gol D. Roger, Edward Newgate aka Whitebeard, Kozuki Oden, Shanks, and his own captain, Rocks D. Xebec.
Roger could possibly beat any character in the series. Although he isn't alive right now, he did clash with Kaido at God Valley where the Rocks crew was annihilated. Arduous as it may be, it is expected of the Pirate King to be able to take on Kaido without much trouble.
Kozuki Oden and Roronoa Zoro both gave him permanent scars with their swords attacks. Keep in mind that neighter fighters have unlocked the ability to forge "black blades." Mihawk should be strong enough to scar Kaido as well. It should also be noted that Kaido considers Shanks to be his equal.
All the damage that Zoro sustained is simply way too much for him to fight anyone who is a capable fighter. For him to fight someone as strong as Kaido and use his blades to channel all the Haki required to kill him is simply not possible.
With his strongest attack, called Bajrang gun, Luffy sent Kaido crashing from Onigashima into the underground of Wano. Kaido was completely knocked out by the ferocity of Luffy's strike and ended up in the same place as Yonko Big Mom.
Gear 5 ("Gear Fifth") is the awakened form of the Gomu Gomu no Mi, which strengthens the user's rubbery body. It also allows the user the ability to manipulate and transform their environment, similar to a Paramecia's awakening. Luffy achieved this ability during his final battle with Kaidou on Onigashima.
They are foils. It's why sanji and zoro can never get along, they have irreconcilable philosophies on how to use their strength. Sanji is a big guy who only shows up to save someone else or he's not interested in fighting. Zoro is a brutal combatant who is ONLY interested in fighting.
He even fought against Captain Rocks on God Valley. Garp may be old right now, however, he is still more than capable of taking on Shanks in battle. This is evident from the fact that he recently set out to fight not just Blackbeard, but his entire crew on his own so as to rescue Koby from the grasp of the Yonko.
Maybe because of the heat of his flame however it's hard to say, it doesn't take anything away from Sanji Luffy who was on the level of a first couldn't hurt Kaido not because his attack was weak but because Kaido's scales are almost immune to blunt damage.
In chapter 1049, Luffy's colossal punch, imbued with the Ryuo technique he learned in Wano, blasts through Kaido's defenses and his flaming hot body, punching the Yonko's dragon form so hard that it falls all the way from the sky to Wano, burying him in the ground.
It's something fans never would have expected to see after Luffy took the first two losses against the Emperor in the arc previously, and it's taken in an even more surprising direction when Kaido started to reveal that he actually has some respect for Luffy.
This is based on him using Haki as his primary fighting form, his skill being compared to Rayleigh (a Haki Master) in SBS, and him being Shanks. So from all that it seems very clear to me that Shanks is not only able to beat Kaido, but that during Marine Ford he either restrained the beast or forced him into retreat.
Chapter 1040 saw the momentous defeat of one of these emperors, Charlotte Linlin, better known by her epithet "Big Mom". Big Mom's defeat by Luffy's allies (for the time being) Trafalgar Law and Eustass Kid, has major implications for the future of One Piece.
3 Can't Beat: Kaido
Even the full Straw Hat crew would have trouble bringing him down, so Usopp on his own doesn't have a chance. Kaido tanked multiple full strength hits from Luffy without a scratch, so already Usopp has no way of harming him.
Following his victory over Yonko Kaido, Luffy is likely to fight someone of the same caliber. This means characters such as the other members of the Worst Generation, such as Law and Kid, along with the other members of the Yonko are likely to be his next opponents.
Whitebeard's power was once labeled to be strong enough to destroy the entire world. Out of all the pirates in the One Piece world, Whitebeard is the only man who could match Gol D. Roger in a fight, making him the strongest Yonko.
Mihawk is said to be close to the same level as Shanks and is even dubbed as the greatest swordsman, so to say Luffy would defeat Mihawk is still debatable in the eyes of many fans.
Shanks team has the strength to defeat kaido. But not 1v 1. Shanks alone can't beat kaido ,he might hurt him but result will be same.
