a lil bit offtopic, I still like the idea of Kaido wanted to rescue ace and Shanks stopped him.
What if he knew about Yamato’s friendship with Ace and he was ok with it. Just powerhouse, his daughter with the son of the king of pirates? What else could he wish powerwise.
So Yamato came to Kaido when ace got captured and ask him the first and only one for something. She never took a present from him since oden. She never aknowledged him, accepted him as father. But this moment came and she asked him in tears:
„Please, save Ace!“
And Kaido, still the father of his daughter, went for it. He was going to save ace. But somehow Shanks stopped him. Maybe surprised him with an attack, sank his ship of something. Probably shanks didn’t expected Kaido to go there for helping.
And since then, Yamato can’t forgive her father. She had one wish in her life. One time she needed that strongest creature in the world, which always gets and takes what he wants. But this time he didn’t. He didn’t fullfiled her wish. So she makes him responsible for ace death and that’s why she ultimately hates Kaido and sticks to oden.
This also brings up Kaidos wish for
Death. Also why he was envied a Whitebeard. He couldn’t fulfill the one wish of his daughter. Which always rips of his heart when he looks in her eyes. That’s why he drinking, why he seeking for death. He is used to feel pain, to get hurt physically. He is used to be beaten, to bleed, to get unconscious. But he can’t take this pain of ultimately having failed his daughter. To see the hate against him in her eyes. Knowing it’s his fault and he never can repair his mistake.
