Kaido in the flashback, happy face: Come and join me, I'll change the world! King!
Kaido has a daughter, Yamato.
Yamato : I want to be Oden! I'm Oden!! Oden led this noble samurais and you killed him! I was there at the execution and couldn't help but be in awe of him. That's when I decided I would take on that mantle! I'll repeat, I am Oden!!
Kaido in the current times, screaming like a madman: Hurry up joker, prepare!! This world must be destroyed!! We'll start the greatest war this world has ever seen!!
