In latest chapter Kaido’s son Yamato appeared for the first time.
Yamato is a tall man, though not nearly as tall as his father, being slightly over twice Luffy’s height. He has long, wild light hair that reaches below his waist as well as a long goatee on his chin.
He wears a hannya mask over his face, which has a pair of dark horns upon its top. He wears a multi-colored kimono with a diamond-shaped design on both sides of his chest, as well as a nio-daisuki on his back. He has cuffs around his wrists with a short chain attached to each of them. He wears a pair of hakama pants and sandals.
Yamato seems to have an aversion to being around his father and his father’s crew, having gone missing during the Fire Festival festivities. In contrast, he is very interested in Monkey D. Luffy, having actively worked to meet him after waiting for him to come to Onigashima. Luffy sensed that Yamato had no intention of hurting him, which Yamato quickly affirmed upon meeting him.
Yamato possesses monstrous strength resembling his father’s, being capable of wielding a large and heavy kanabo and using it to defeat Ulti, an Ancient Zoan user and one of one of the top members of the Beasts Pirates, with just one blow!
Yamato is definitely a top tier in Wano. I mean, he one-shotted Ulti in her Ryu Ryu no Mi, Model: Pachycephalosaurus transformation when she was about to use a full-power headbutt on Luffy. Basically, she was in hardest-of-hard-heads mode and Yamato still one-shotted her with a blow to the head!
