As she possesses a pair of black horns, Ginrummy is most likely a Gifter and thus have a SMILE fruit and is able to use animal transformations, though the name of the fruit is unknown. Jack personally addressed her during his assault on Zou, also implying a high rank in the crew.
Sheepshead is the headliner of the Gifters in the Beasts Pirates. He ate an Artificial Devil Fruit known as SMILE, which grants him the ability to transform his hands into the horns of a sheep.
Scratchmen Apoo is the captain of the On Air Pirates. After Jack’s defeat, Apoo contacted Kaido and informed him that communications with Jack had been lost. Referring to the Yonko as “Kaido-san” and reporting this news to him via a Den Den Mushi, it indicated that Apoo was now assisting him on some level.
Apoo appears to have a Devil Fruit connected with music. This ability, which he refers to as Tatakau Music, allows him to transform his body into various musical instruments which he can play. By playing specific notes and tunes, he can release music that causes damaging effects to his opponents, the type of damage being determined by what he plays, and seems to have hypnotic effects.
Basil Hawkins is an infamous pirate from North Blue known as the “Magician” and the captain of the Hawkins Pirates. After encountering Kaido, he joined the Beasts Pirates and became one of the crew’s Headliners.
Basil Hawkins’ as-of-yet unnamed Devil Fruit ability enables him to redirect any instances of physical damage inflicted upon him to another person using straw voodoo dolls, leaving him unharmed but forcing his victim to take damage amounting to what he would have. The Devil Fruit also enables him to transform into a giant scarecrow-like entity, resembling a giant voodoo doll, with metal nails functioning as claws/fingernails.
X Drake is a former Marine rear admiral who later turned pirate and the captain of the Drake Pirates. Currently, he and his crew are affiliated with the Beasts Pirates.
Drake possesses what is referred to as a “rare, Ancient Zoan Devil Fruit”, giving Drake the ability to transform into a theropoda dinosaur.
In this form he is large and powerful enough to directly wound one of the Pacifista troops by biting it in the head, something that is quite difficult due to the cyborg’s heavy armor. It is also mentioned that the more carnivorous a Zoan fruit is, the fiercer the combat abilities gained from eating it, which suggests that Drake’s Devil Fruit makes him a strong and formidable opponent.
Drake has shown that he is capable of using Busoshoku Haki when he easily defeated Caribou, a Logia user.
#JACK THE DROUGHT
Jack the Drought is one of Kaido’s three right-hand men known as the “Disasters”, and the captain of the Mammoth.
He possesses tremendous strength and endurance, having fought equally with the Mink Tribe, primarily its two rulers Inuarashi and Nekomamushi, for five days and five nights without taking a break; meanwhile, the Minks, specifically Inuarashi and Nekomamushi, took turns every twelve hours. Although the Minks eventually gained the upper hand, they were never able to suppress Jack himself.
Jack has eaten the Ancient Zoan-type version of the Zou Zou no Mi, which allows him to become a mammoth, granting him immense size and strength; in this form, he leveled part of a city by simply swinging his trunk.
#THE SHOGUN OF WANO
Kurozumi Orochi is the current shogun of Wano Country and an ally of Kaido of the Yonko. Orochi seems to be cruel and oppressive. Sometime in the past, Orochi joined forces with Kaido and the Beasts Pirates. Orochi and Kaido went after the Kozuki Family to discover a secret about Raftel that Kozuki Oden knew, and they executed Oden and his wife. They then pursued Oden’s son Kozuki Momonosuke and his retainers, but Momonosuke and his three guards managed to escape Wano.
Kurozumi Orochi will probably be the second strongest villain of the Wano arc.
As one of the Yonko, Kaido is among the strongest pirates alive, renowned as the “Strongest Creature in the World”. He attempted to take Whitebeard’s life, something few would dare, and subsequently clashed with Shanks. When Gekko Moriah was in his prime, Kaido fought him and emerged victorious, having killed his entire crew.
Perhaps the greatest sign of Kaido’s strength is his apparent inability to die due to his tremendous toughness and durability. He has been caught and tortured 18 times, and people as powerful as the Marines and other Yonko have attempted to execute him 40 times only to fail as Kaido survived every single attempt because every single execution weapon broke when being used on him. Most notably, Kaido has jumped from 10,000 meters from the sky onto the ground, creating a massive shockwave strong enough to sink a large ship nearby, and emerged only with a headache; it has even become a hobby for him to attempt suicide, only for it to fail.
