Kaido announces to his crew that he have a plan called the "New Onigashima Project". Prior to the Kaido first heard of Luffy after finding out that he worked with Trafalgar Law to destroy his SMILE production. Kaido meets with the Flying Six, Jack, and King. He is stated to be a being that is near immortal and simply cannot be killed. He command Kaido was sent crashing to the ground. When Kaido is faced with strong opponents like Luffy or Eustass Kid, he is willing to allow them to join his crew despite the problems they have caused him or their defiance. Orochi was against Kaido taking the Flower Capital and Kaido responds by decapitating him with King's sword to Orochi's men's horror. As Kaido looks down the stage to see what is going on, the Nine Red Scabbards appear behind him and the All-Stars.

Kaido was frustrated by Momonosuke's response and proceeds to get to the execution until an explosion caught his attention. Kaido is a tan, middle-aged man who cuts an imposing figure due in equal measure to his great heightKaido's head, atop his bulky neck, is disproportionally small as well (smaller than his hands) and has a massive pair of gray-white, sharp-pointed horns come out of its sides, curving slightly to the front, then upward. Word of Doflamingo's defeat and the destruction of the SMILE factory brought Kaido mourning at his loss much to his drunken emotional sorrow.In the end though, Kaido was merely using Orochi as a pawn, and once Kaido revealed his New Onigashima Project, he beheaded Orochi when the latter objected to it. The group proceeds to attack Kaido and fall off the stage. He easily defeated Luffy, a pirate with a bounty of 1,500,000,000 who used both third and gear fourth to attack but Kaido knocked him with a single strike from his spiked mace, showing a glimpse of his abilities.

Kaido later gets news that one of his three calamities, Kaido appears and orders his men to remove the seastone chains from The evening of the Fire Festival, Kaido is shown to be drunk. When Big Mom attempted to invade Wano Country, Kaido feared it would become an all-out war and furiously ordered his crew to stop her, especially after being aware that Big Mom's powerful children were accompanying their mother.

Kaido screams in pain and falls onto the ground. When Kaido is faced with strong opponents like Luffy or Eustass Kid, he is willing to allow them to join his crew despite the problems they have caused him or their defiance.
