Yamato’s mother is Gloriosa. As an old lady she goes by Elder Nyon. Why this is 100% the case and Oda hinted this across the story. Gloriosa said she had to leave the island because of the love sick illness and the only reason she survived is because she left.

Kaidou is a pretty evil and sinister dude. His wife isn’t gonna just be anybody. And the reason they would fall in love with Kaidou isn’t gonna be for his personality. But what is the main thing established about Kaidou?

The main thing Oda has highlighted about Kaidou is his STRENGTH. The strongest creature, the strongest pirate, crew drawn to him due to his sheer strength.

Oda established that in Amazon Lily. Strength is beauty there. The stronger a person is the more beautiful they are. This means land, air, and sea is considered a handsome guy over there.

Gloriosa is a former Amazon empress. The Empresses such as Hancock fall in love for simple shit. Simple shit such as kindness, Hancock the most beautiful woman fell in love with the only dude who doesn’t think Hancock is beautiful. So, all it takes is simple things for them hit by the love illness. Kaidou beat Gloriosa in a fight and she fell in love with him because of his STRENGTH.

And now think about Yamato’s character. She is a strong ass woman like Hancock, loves to fight, and cares more about fighting than femininity like Nami. This is basically the Amazonians. She is exactly like them. The Amazonians are known for being strong woman like Yamato. It’s clear Kaidou wanted a son. But that’s the thing the Amazon woman can only have female children. They can’t have males.

Kaidou also has very hinted ties to Rusukaina. The dudes name is Hundred Beast or King of the Beasts Kaidou. When Luffy went to this island, Rayleigh said there were 500 animals here stronger than him. Maybe Kaidou got this name by beating a hundred beasts on that island at a young ass age.

The reveal of Rusukaina is 597 an island where ONLY THE STRONG SURVIVE, an island of wild savage beasts. The reverse of 597 is 795. Just happens to be Kaidous intro chapter. Called Hundred Beast Kaidou or King of Beasts Kaidou. This number is actually significant 500. It just so happens this is the number that law said in regards to the smiles. Kaidou had roughly 500 devil fruit users in his crew who ate this smile. The devil fruit chemical uses the DNA of animals. What if Kaidou used the DNA from these 500 beasts of Rusukaina to try and create the smile.

Narrator says the WEAK LIVE THE STRONG DIE. Going back to this natural selection shit that 597 reinforced.

And a big point I believe Oda has used to hint the connection between Yamato and Gloriosa… Is the vivre card. Yamato was the one who told Ace how the vivre cards work. So the minute Ace card started to burn up she would have known he was in trouble.

But Kaidou doesn’t really teach Yamato that much. She likely learnt his attacks just copying him after losing so many times. So how did Yamato learn about this vivre card information?

I strongly believe she learnt this information from her mother aka Gloriosa. And that’s her only vivid memory of her mother. And now think for a moment who was the one who told Luffy how the vivre cards work and that Ace was in deep shit. Yep it was Gloriosa.

Yamato was unable to tell anybody close to Ace that he was in danger or go to save him herself. But the person who told her how the vivre cards work her mother told Luffy.

You’re probably thinking how is this old ass lady the wide of Kaidou when.

– She is small af.

– She seems way older than him

Well one. There are 2 characters who look roughly around her height. Shinobu and Hyogoro. Both of these people were studdly back in the day. And Shinobu was extremely beautiful.

Kaidou and Gloriosa are based of the story of the Enoshima dragon and the water maiden Benzaiten.

The dragon terrorised a village and caused natural disasters and all sort. Very similar to Kaidou who has natural disaster like abilities Zoro reinforced this and he is obviously terrorising Wano. Benzaiten told the Dragon to stop what he was doing and he fell in love with her. In some versions, she rejects him and in others not but regardless there are extremely similar characteristics to Benzaiten and Gloriosa.

Benzaiten originated from an Indian goddess and Gloriosas, the flowers which Gloriosa was named after, grow in India too! Gloriosa superba is even Tamil Nadu’s national flower. It is also said to be a flower associated with suicide. Which just happens to be Kaidou’s favourite hobby. Maybe his reason for constantly committing suicide has something to do with her.

It is also said the Benzaiten is always seen with a white snake. Accompanied by a white snake messenger. This just happens to be something that specifically Elder Nyon had with her. Funny enough Yamato uses an attack called “white snake”. An attack that is very different to any other attack she used. And this attack happens to be done in combination with Luffy’s snakeman attack that seems to take inspiration from THE KUJA and Snake Princess.

Oda has also made a trend with these small weak fragile characters being extremely important and successful in their youth. Such as Hyogoro. And Elder Nyon is another character like that.

Benzaiten is said to be from an island of ONLY WOMAN. Very strong evidence. She is said to be very wise and knowledgeable. She told Luffy about the nature of the vivre card, she understood Luffy’s pure intentions while the other amazon’s didn’t see the bigger picture. She knew about Luffy’s actions taking down the Celestial Dragons.

And even just from a logical standpoint. We know Yamato is a beautiful character but she isn’t like Nami or Robin. She is a brawler she loves to fight. And she likely felt insecure about being a woman. Since woman are generally told to avoid violence and told to act feminine. She likely calls herself the son of Kaidou because of this. If she learnt she was from Amazon Lily where these woman love to fight, it would make alot of sense why she is the way she is.

Yamato is very similar to the Amazonians. Extremely strong for a woman and very naive about the outside world. Both Wano and Amazon Lily are isolated nations.

Also you can actually see a parallel between Kaidou and Gloriosa. When Kaidou met Gloriosa, he was a nobody and she was an empress. Now Kaidou is an emperor and she is a nobody.
