Monkey D. Dragon vs. Kaido: Who Would Win in a Fight?
Monkey D. Dragon vs. Kaido: Who Would Win in a Fight?

One Piece is an anime that certainly has its share of strong and powerful characters. Kaido of the Beasts is one of these characters, as he is considered one of the strongest characters in the entire series. Although his role has been reduced since his defeat by Luffy in Wano Country, he is still a formidable character and ripe for comparison. In this article, we will compare him to Luffy's father, so we can determine whether Monkey D. Dragon is stronger than Kaido or not.
Since Dragon's true powers are unknown, we can't say whether he's stronger than Kaido or not. This is probably not the case, since Luffy was only able to defeat him after activating Gear 5, but it's possible that Monkey D. Dragon has unknown powers that we're not aware of, so he could be stronger than Kaido, but we can't really determine the winner in this one.
Now that you have the short version of the answer, the rest of the article will be divided into three sections, the first two of which will introduce the characters, their powers, and their abilities. We had to resort to this analysis because Dragon's powers and abilities are completely unknown, and we don't really know how he compares to Kaido in certain categories, since we don't even know how he ranks in those categories. Ultimately, we'll expand on our answer a bit.
Monkey D. Dragon and his powers
Monkey D. Dragon, known as the world's worst criminal, is the supreme commander of the revolutionary army and the most wanted and dangerous criminal in the world. He is the father of Monkey D. Luffy and the greatest threat to the World Government. Although a complex character, he has shown that he cares for his son, as well as his own revolutionary ideals.

Monkey D. Dragon is the leader of the Revolutionary Army and has complete control over the organization. It has been hinted that Dragon may be an incredibly powerful person; the World Government has dubbed him "the world's most wanted man" and is terrified that he might rebel against them along with Whitebeard, who has become a powerful threat in his own right.
He is also the son of the legendary Marine Garp and the father of Luffy, a notorious pirate. Proof of his great power is that he trained Sabo, the second-in-command of the revolutionaries, who was already a strong fighter in his childhood. With his acquired training, years later, Sabo could be on the same level as Fujitora, the Admiral of Naval Headquarters.
When Sengoku told everyone about his relationship with Luffy, most people were stunned, including Gecko Moria, then a member of the Seven Warlords, and the members of the Whitebeard Pirates, very powerful people under the command of Whitebeard, the most powerful pirate. This reputation was enough to make Luffy a potential threat in the future.
He has powerful subordinates such as his commander Emporio Ivankov and Inazuma who are relatively low ranking, except for his second in command Sabo who could only fight Burgess and Diamante who had previously worked as commanders for other fearsome Eater Pirates, the Mera Mera no Mi, which greatly increased his power and brought his leader's power to a level similar to that of an emperor.
Ivankov comments on Luffy's will to live and inordinate power and that this only proves the idea that he is in fact Dragon's son, implying that Dragon has a similar will. When Dragon arrived in Goa, people noticed that it was windier that day, such as when it didn't snow for a full day on Drum Island due to Portgas D. Ace's presence. It should also be noted that every time (except at the Revolutionary Army headquarters) a storm appears or is already there.
Kaido and his powers
Kaidou the Beast is the leader and captain of the Beast Pirates who served as one of the Four Emperors until he lost that title when he was defeated during the Assault on Onigashima. He was also an apprentice of the legendary Rock Pirates during his youth. He was the third emperor to be mentioned and the last to make an appearance.

He was one of the Four Emperors and thus part of the elite of piracy, where he is known as "the most powerful creature." He has a bounty of 4,611,100,000 Berries, currently the highest and second only to Whitebeard and Gol D. Roger. Before the conflict at Marineford, Kaidou attempted to take Whitebeard's life, something few would dare do, though he eventually confronted Shanks.
When Gecko Moria was at his best, Kaidou fought him and emerged victorious, devastating his entire crew. The Five Elders mentioned that Kaidou is one of the few people capable of stopping Blackbeard. Trafalgar Law stated that Kaidou could easily assassinate Donquixote Doflamingo, a world-renowned and extremely powerful pirate.
Law also theorized that even with an alliance with the Straw Hats, his chances of overthrowing the Emperor were reduced to 30%. This claim may be debatable, however, as at the time Law did not pose a real and open conflict with Kaidou. The Emperor was able to defeat another member of "the worst generation," Eustass Kid, with apparent ease and refused to take Luffy and Law's alliance seriously, regardless of his accomplishments, viewing the defeat of a Sea Warrior as minor and of no real importance to him.
Kaidou then effortlessly defeated Luffy himself, knocking him unconscious with a single blow. Kaidou can also take on Big Mom of the Four Emperors, as evidenced by the strength of their clash, which was strong enough to split the sky in two, similar to the clash between Whitebeard and Shanks, and fight her for two days without sustaining any injury.
Like the rest of the Emperors, Kaidou commands a large number of subordinates and other pirate allies, such as X Drake and Scratchmen Apoo. With Caesar Clown and Doflamingo as his partners, Kaidou has managed to create an army of over 500 artificial Zoan Devil Fruit users, the Gifters.
Monkey D. Dragon vs. Kaido: Who Would Win?
Ultimately, there's not much we can say about this matchup, since we don't know much about these guys in the first place. Granted, we know everything about Kaidou, but in comparison, we know almost nothing about Dragon, so it's kind of even.
Theoretically, Kaidou should be stronger than Dragon. He is undoubtedly one of the strongest characters in the series and was able to defeat Luffy several times until Luffy activated the godly powers of his Devil Fruit and eventually Gear 5. It wasn't until Luffy became ridiculously overpowered that he was able to defeat Kaidou, and that speaks for itself when it comes to Kaidou's powers.
Now, when it comes to Dragon, we know absolutely nothing; we've never even seen him use any of his powers; in fact, we only know them by reputation. He's feared around the world, and people generally try to avoid him, but it's unclear whether that's because of his actual powers or his reputation. It's also assumed that he's more powerful than the other members of the Revolutionary Army, but we can't even confirm that.
In any case, we are unable to draw any conclusions here. It is completely unknown whether Dragon is stronger than Kaidou, simply because we have absolutely no idea of Dragon's exact powers and abilities.
