I think every top tier pirate crew have a member or two with king's haki
(PK) Roger - Rayleigh, Oden and Bullet (NC)
WB - Ace, Oden and probably Marco
Dummy thicc - Katakuri
Kaido - King (His name is literally king but Oda might just be trolling us) and Yamato
Shanks - Ben probably has it
BB (50% chance he has it) - Shiliew or Kuzan probably
Luffy - Zoro
Rocks and half of his crew...I wouldn't bet against Shiki, Wang Zhi, Silver Axe and Captain John having it too
