Aunt has become a prisoner, why did Kaido keep her?

Because the latter thinks that Auntie's personal ability and comprehensive ability are very strong, and she also wants to subdue Auntie through various interests, so she will stay.

Because Auntie's ability is still very strong. And her fruit abilities are also very special. So Kaido left her to prepare for the future.

Because when they were in the Rocks Pirates, Big Mom and Kaido were partners. After the aunt accidentally obtained the Phantom Beast Fish Fruit, she gave the fruit to Kaido, so Kaido owes him a favor.

First of all, Kaido and Aunt were originally the pinnacle of the same period, they are also legendary characters standing at the top of the pyramid, they naturally know the strength of each other, at the same time, Kaido and Aunt also had an adventure together, far away in the Roger era There can be no big gap in strength, when Aunt and Kaido met on Ghost Island, the two slashed each other, evenly matched, and Auntie's strength is completely worthy of Kaido. And Kaido still owes his aunt a big favor, which makes Kaido very jealous of his aunt.

Kaido is different, when he fought with Mitsuki Mita, he left a huge scar on his body, you must know that for the strongest creature in the world like Kaido, it is a shame. Fighting against the Five Emperors Luffy, he didn't dare to fight back after being beaten, if it weren't for the sudden thunderous gossip of a sudden blow, he would be a foodie, but if this old woman gets serious, it is estimated that the entire Ghost Island will be gone, so when Kaido saw the aunt, although he was still very stubborn in his mouth, he actually showed some jealousy of the aunt, after all, Kaido was not sure of defeating the aunt.

First of all, in the countries of Auntie's own territory, basically the people of the Auntie Pirates are more afraid of Auntie. They are all more scared when they see Big Mom angry, because Big Mom's fruit ability can take the life of someone who is afraid of her. Kaido and Aunt are both the Four Emperors, and they are also big people who have been galloping the sea for decades, both of them know very well the realm of their strength, and they both understand that violence is not the best way to solve the problem, both of them are scheming old foxes, unless they reach the most.

In the latest plot of One Piece, Big Mom led its pirate group to land in Kaido's territory and the country of Wano, which made the situation in the country of Wano even more chaotic, and the words of the three disasters in the face of the big aunt seemed to look down on the big aunt, but in fact, the big aunt had already hit the door, and he was a beast and couldn't say that he was a reckless man, and the two kings of Zou Island couldn't beat cats and dogs, and they knew how to use poison, and he didn't get caught robbing Brother Ming, which proved that there were also some means. If Jack is against the Emperor, he will use it if he can win by despicable means, and if he can't win, he will find a way to get out.

That's because Aunt has a great kindness to Kaido, and Kaido's Devil Fruit was given by Auntie, so Kaido is so jealous of Auntie.

Because Auntie's strength is very powerful, and there are a lot of tricks, she is afraid of her.

Kaido is not afraid of aunt, he respects each other very much, because they have fought together, and they know each other's strength very well, so it seems that there is some jealousy.

It's because Kaido has fought with Auntie, and Auntie's strength is also very strong, and he hasn't fought before.

Kaido is not really ally with Big Mom, it can be seen from the two aspects of laughter and rolling, on the one hand, in the context of the One Piece manga, the four emperors are all going to the position of One Piece, and the four emperors are not harmonious, and even tilt towards each other, and Kaido and Big Mom still have old grudges. On the other hand, from the details after the alliance, it can also be found that Kaido did not meet the basic requirements for the aunt to form an alliance, and did not be honest with the aunt and share resources. And the reason why Kaido pretended to form an alliance with Aunt Bangzhou is to stabilize Aunt and use Aunt Aunt's strength to deal with the internal affairs of the country of Wano.

Their goal is the same, Kaido must have his own plans, and it is impossible to really cooperate with Big Mom.

At that time, it was too easy for him to agree, after all, he knew the ambition of the aunt, and there was a conflict of interest between them.

Kaido and Big Mom are not really aligned, Kaido wants to stabilize the situation, and Big Mom wants to destroy Luffy.

The Four Emperors were originally rivals competing with each other, and Kaido, Big Mom, and the old grudge One Piece This comic has always revolved around the position of One Piece, and the pirates who go to sea are all characters with dreams, courage and the goal of One Piece, otherwise they will not choose to go to sea, and they will either be exploited and enslaved by the Draco people on land, or join the revolutionary army to fight against the Draco people and go to sea to become pirates, which means that they are enemies of each other, and the Four Emperors are characters who stand at the apex of the pirates when One Piece does not come out, Like an emperor, he reigns in the second half of the Great Voyage of the New World.

Because Big Mom's goal is Luffy, maybe Luffy is just a disguise, in fact, for the ancient weapon king. At a critical moment, Big Mom may turn back against Kaido.

The relationship between Kaido and Big Mom is not said in the anime, but Kaido and Big Mom are most likely husband and wife.

Because Kaido and Big Mom were both crew members of the Rocks Pirates when they were young, many years later, Big Mom still remembers Kaido's ** clearly, and Kaido looks very helpless when facing Big Mom many times. From these details, it can be seen that the two used to have a great relationship.

As the supreme leader, there is too much ** information, which should not have been leaked, but the aunt clearly knows how much his private ** is, and it can be seen from this detail that the relationship between the two is very unusual.

Because the biggest character in this anime is Luffy, as long as it develops over time, then Luffy will eventually become the most powerful existence, even if they are very dominant now, it will not be useful to wait until the later stage.

Because they are villains, villains are destined to be defeated in most stories, and there is no suspense in being defeated in One Piece.

Because Kaido and Big Mom's alliance is not considered justice, because justice, although it may be late, will never be absent. In addition, Luffy started the war to save Wano Country.
