The King of Beasts, Kaido, is one of the Yonko of the New World in One Piece, and also the man who is known as the 'strongest creature in the world'. Boasting an enormously bounty of 4.6 billion berries, Kaido is feared across the world as a pirate whose cruelty knows no bounds. Being a Yonko, there are few who can stand up to the might of this man, let alone defeat him.
However, it is a known fact that Kaido has been defeated 7 times, and captured 18 times in the past. As such, beating him isn't as arduous a task as killing him is. Here are 10 characters who can beat Kaido in One Piece.
10 Monkey D. Luffy
The Captain of the Strawhat Pirates, Luffy is the man known as the Fifth Yonko of the Sea. With a bounty of 1.5 billion, Luffy is already a fearsome pirate. When compared to Kaido, Luffy is, in no way, an equal to him yet. However, Luffy aims to take down Kaido at Wano Country, and when he says something, he certainly does it.
Whether he'll be stronger than Kaido or not is a completely different question, but we're certain that Luffy will defeat Kaido, one way or the other. To take him down, Luffy has been honing his Haki at Udon Prison for several days.
The current Fleet Admiral of the Marine, Akainu is, without a doubt, one of the strongest characters in the entire series. With the Magu Magu no Mi, Akainu can manipulate and turn into Lava as he likes.
According to Oda, his Devil Fruit boasts the offensive power of the highest class. That, along with his top-tier haki, gives him a strong footing against Kaido. Of course, defeating Kaido will likely be an uphill task for Akainu, but tenacious as he is, there is a possibility that he'll pull it off.
The former Fleet Admiral of the Marines, Sengoku is a man of many talents. Apart from his incredible strength, he is also a shrewd man, known for his sneaky tactics. Sengoku is one of the legends of the One Piece world, having history against the likes of Whitebeard and Roger.
As such, there's no reason why he shouldn't be able to defeat Kaido in a fight. Just like Kaido, Sengoku has eaten a Mythical Zoan type of Devil Fruit. His Haki also seems to be immensely refined, and in a fight against Kaido, he would certainly not back down easily.
7 Monkey D. Garp
Also renowned as 'Garp The Hero' and 'Garp The Fist', Monkey D. Garp is a Vice-Admiral of the Marines. Being their strongest known member in history, there's no denying that Garp is capable of taking on Kaido.
He's previously fought against the likes of Rocks, and even Gol D. Roger. Garp doesn't use Devil Fruit powers, making him a completely Haki based fighter. Although he may not be able to defeat him as he is now, in his prime, Garp would certainly prove to be more than a challenge for Kaido.
6 Monkey D. Dragon
The son of Garp, Dragon is the leader of the Revolutionary Army in One Piece, and also the worst criminal in history, according to the World Government. Although much of Dragon's strength remains unknown, the fact that he's managed to challenge the Government head-on and even give them a hard time implies that Dragon is very powerful.
His commander, Sabo, was capable of holding his own against an Admiral without any apparent trouble. As such, Dragon could very well be a match for Kaido.
Akin to Kaido, Shanks is one of the Yonko of the Sea. According to Brannew, Shanks is the youngest of the Yonko, having been given the title about six years prior to the current timeline. Like Dragon, most of Shanks' strength remains shrouded in mystery. It is speculated that Shanks uses just Haki to defeat his opponents, and that's some incredible feat for a Yonko.
Whether Shanks can defeat Kaido or not is unknown, but he is certainly on par with Kaido, if not stronger. Interestingly, the two have already fought once in the New World, and Shanks emerged unscathed at Marineford after the fight.
4 Big Mom
The Queen of Totland, Charlotte Linlin, also known as Big Mom, is also one of the Four Emperors of the Sea. As the Captain of the Big Mom Pirates, she possesses incredible strength, enough to have earned her a bounty of 4.3 billion berries. Big Mom is equal to Kaido, from what we've seen in the story.
The two share a past related to Rocks, so they've likely fought each other back in the day. Recently, they clashed at Wano, only to stalemate even after fighting continuously for 13 hours. If they do go all-out, Big Mom could potentially defeat Kaido just as much as he could defeat her.
The Admiral of the Blackbeard Pirates, Marshall D. Teach, also known as Blackbeard, is likely the main antagonist of the entire One Piece series. He holds tremendous powers which saw him rise to the status of a Yonko during the two-year time-skip.
Blackbeard wields two Devil Fruit powers which include Paramecia type Gura Gura no Mi, and the Logia type Yami Yami no Mi. Claiming to be the strongest in the world, Blackbeard has a good chance of taking down Kaido in a fight. Interestingly, this is a fight that we might get to see at Wano, with large sections of fans suggesting that Blackbeard could potentially come for Kaido's Devil Fruit.
2 Gol D. Roger
The Pirate King, Gol D. Roger was once the strongest man in the entire world, along with Whitebeard. Boasting a bounty higher than 5.5 billion berries, 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. While it is largely unknown what weapons, if any, Roger uses in combat, it is theorized that just like Shanks, he used Haki as his primary weapon of choice.
The Pirate known as the strongest man in the world, Whitebeard is the only man who is known to be able to match Roger in combat. According to Garp, he is the 'King of the Seas', while Sengoku refers to him as the 'man with the power to destroy the world'.
Even in his old age, Whitebeard was capable of taking down Marineford all by himself and defeat thousands of their members in the process, including the likes of Vice-Admirals and Admirals. In his prime, Whitebeard would've been a monster in combat. Unfortunately, we haven't seen anything of him from his prime days, but his expected to be able to deal with the likes of Kaido without too much trouble. His title, and accomplishments speak for themselves!
