7 – KUROZUMI OROCHI
Kurozumi Orochi ate the Hebi Hebi no Mi, Model: Yamata no Orochi, a Mythical Zoan-type of Devil Fruit which allows him to transform into an eight-headed serpent.
This fruit grants the user eight separate, extremely long-necked heads, each one capable of speech on their own. It appears that the user has some degree of control about the number of heads that can sprout at once, with eight being the maximum limit.
In this form, the user is able to bite opponents with a considerable amount of strength and range, the latter due to the elongated necks.
The user also has a fair amount of durability in their transformed state, with Orochi being capable of sustaining damage from a ceiling collapsing on his head with few repercussions.
6 – JACK THE DROUGHT
Jack has eaten the Zou Zou no Mi, Model: Mammoth, an Ancient Zoan-type Devil Fruit, which allows the user to transform into a mammoth hybrid and full mammoth at will.
The full mammoth form granted by this fruit gives the user a massive frame, significantly increasing Jack’s already abnormal size. Jack can level buildings with a single swing of his trunk and leave imprints of his feet on the ground just by stepping on it.
5 – QUEEN THE PLAGUE
Queen ate the Ryu Ryu no Mi, Model: Brachiosaurus, an Ancient Zoan Devil Fruit that allows him to transform into a brachiosaurus hybrid and full brachiosaurus at will, granting him an immense boost to size and bulk.
In his full brachiosaurus form, Queen’s size is comparable to that of a giant, as Queen towered over Big Mom, who herself is extremely tall at over 8 meters. The user’s immense weight can be used as a weapon, as very little will be able to withstand the crushing pressure of their massive transformed body.
4 – KING THE CONFLAGRATION
King the Conflagration ate the Ryu Ryu no Mi, Model: Pteranodon, an Ancient Zoan-type Devil Fruit that allows him to transform into a pteranodon hybrid and full pteranodon at will.
This fruit gives him the ability of flight, and he can perform extremely powerful aerial attacks from mid air as shown when he toppled the Queen Mama Chanter, a gigantic ship, with enough force to throw Big Mom off.
