Yamato was a horribly written character. For a person who is the daughter of kaido, you'd think Oda might make their relationship even a little bit deeper than "Yamato good, Kaido evil".
When she was first revealed, I thought we were going to get a flashback with Kaido's mother, with Oda showing that yeah, even Kaido feels love and human emotion. Nope, lmao.
Thanos, Nebula, and Gamora were written so much better in the MCU than Lamato and Laido.
