- By excluding Yamato from the Straw Hats, we maintained the balance and dynamism of the monster trio.
- With her unique abilities, the possibility of Yamato joining the crew could significantly change the hierarchy of power.
The Wano Country arc included the debut of many amazing fighters. one piece Fans were very happy to see them in action. Of all the people, I think Yamato was the most interesting. Although she was Kaido's daughter, she loved Kozuki Oden. She read Auden's diary and was fascinated. In fact, she began calling herself Oden and openly opposed her father's sadistic ways.
Yamato met Ace several years before the current timeline. During their meeting, Ace talked to Luffy about his dreams. Yamato immediately remembered that Roger also used the same words he had read in Oden's manuscript. So I waited for Luffy to come. Yamato finally met Luffy when the Straw Hat Pirates headed to Wano.
Upon seeing him, she expressed her desire to join the Straw Hats, and Luffy didn't seem to mind. So most fans were expecting Yamato to become a Straw Hat by the end of the arc. After Kaido's defeat, Yamato seemed to have a change of heart, and she decided to stay behind. Her decision left fans baffled, but it turned out to be the right choice. Because if Yamato had joined, it would have ruined the dynamic of the monster trio.

Yamato was a powerful Oni princess
For this speculation to make sense, fans need to remember Yamato's strengths. She was exposed to battle and bloodshed from an early age, making her physically and mentally fortified. Yamato can use all three types of Haki, which is an impressive feat in itself. But what makes her truly special is that she uses advanced Conqueror's Haki. Until the Wano Country arc, fans had no idea that Conqueror's Haki could be infused into his attacks.
My name is Yamato. I am Kaido's son.
Over time, it became clear that advanced Conqueror's Haki significantly increased damage output. Almost every great fighter in One Piece can use Conqueror's Haki in battle. Yamato having access to such destructive abilities therefore places her in the elite category.
Yamato mastered the devil fruit
In addition to having such powerful Haki, Yamato is also a Devil Fruit user. At some point in the past, she consumed Inu Inu no Mi, Model: Okuchi no Makami. It is a mythical animal-type devil fruit that can transform into a white fox, which is said to be the guardian deity of Wano.
Yamato can use both full beast form and hybrid form, showing that she has great mastery over the Devil Fruit. Yamato's strength was further revealed during his one-on-one battle with Kaido, a feat that only Luffy could boast. Not only did she delay Kaido, but she was also able to cause damage to him. Now that the level of her power is clear, it's time to discuss what negative impact she had on the Straw Hat Pirates' trio of monsters.
Yamato's influence on the monster trio
Oda made the right decision by keeping Yamato in Wano.
The monster trio consists of Luffy, Zoro, and Sanji. All three are excellent warriors that the rest of the crew can rely on in times of danger. As the captain, Luffy is clearly the strongest of the three. He is followed by Zoro and then Sanji. Luffy can use all three types of Haki and their advanced versions. Zoro can use all types of Haki, but lacks mastery over them. Meanwhile, Sanji only has access to two types and, like Zoro, cannot use the advanced version.
So if Yamato were to join the crew, he would be the strongest member after Luffy. This would completely destroy the dynamic of the monster trio. Sanji is completely pushed out, and Zoro falls to third place. Fortunately, Oda used common sense and decided to leave Yamato in Wano. However, fans should not rule out the possibility of Yamato joining the Straw Hat Pirates at some point.
