King the Conflagration is an All-Star of the Beasts Pirates, Kaido's three closest confidants known as the Disasters. He is part of a yet-to-be-identified race that is otherwise considered extinct. Due to his actions and role, he is a major antagonist in the Wano Country Arc. King is an extremely large man who towers over normal humans, though still standing a fair bit shorter than Kaido and fellow All-Star Jack, at a height similar to Queen's. While less widely built than the other two All-Stars, King is better-proportioned than either, being well-muscled and broad in the shoulders (but not overly top-heavy like Jack) with long limbs. Notably, a plume of fire ever rises from his back, befitting his epithet. King's natural appearance is a mystery, seeing as he keeps himself clad in a dark uniform that bares no skin. Its bottom layer is a form-fitting, gimp-like bodysuit made of black and dark-blue leather, with lighter-blue, white-studded leather bands tied variously around. Visible of such garment are the head and neck areas, the latter showing a zipper in the middle and two of said bands left and right. The head portion, a full-faced mask, leaves only two holes for King's narrow, reddish eyes (being fully black around the eyes, otherwise dark blue).
Below the eyes is leather of flame-like shape flanking a central, triangular strip of light blue to mark off the nose, mouth, and chin section (also beset with studs). Topping the eyes are blue-lensed, gray-rimmed goggle pieces and on each side of the head, connected by a studded base, is a large, black spike akin to a horn. Five more such spikes, only smaller, are located further on top upon a light-blue band that runs coronally into another one positioned like a headband, and crossing yet another that goes sagittally, with airholes around. King's dark-blue pants, possibly part of the suit, each have three studded leather bands wrap around their upper halves plus a ring of the same material on each knee, and go inside black, high-heeled boots (once again with studded straps) whose high shafts end with jaggy, studded fold-overs. On top of the bodysuit is a dark-blue, double-breasted leather jacket, ten-buttoned in gold with notch lapels that have red, square skull patches (edged in gold) sewn on, and wherefrom white ruffles emerge. Running straight down each side of the waist are two columns of yet more studs, and flat, two-part shoulder pads (black and double-trimmed with studs) are present on each side, down the upper arms with three curved spikes atop either (the outer ones the biggest). The tight sleeves of the jacket (each with two additional, stud-covered bands topping thinner strips along with three very small, white spikes above the wrists) are cuffless, ending in black gloves. Finally, King has a pair of large, black-feathered wings sprout from his back. Though it is unconfirmed if they are natural, their disappearance with King's pteranodon transformation may imply that they are. In his full pteranodon form, the aforementioned flames further engulf his back. King is a stern man who generally keeps a cool head, being rarely seen showing strong emotion. Like Queen, he is often extremely rude toward and critical of crewmates, constantly deriding his fellow All-Stars, especially Jack, for their perceived failures. According to Queen, King is also a "torture-loving pervert" (though what this means exactly has yet to be specified).
Showing initiative and seeming good at making big decisions under pressure, King personally engaged Big Mom and her crew to keep them from entering Wano despite not being ordered to do so by Kaido. Later in Big Mom's presence, King showed himself to not be intimidated by her, despite his surprise at her survival, even bluntly refusing her offer to join her. King even took the initiative to summon the Tobiroppo after hearing Kaido was looking to address a problem with Yamato, and acted conniving by framing the summons as one from Kaido due to knowing the Tobiroppo would not answer to him. While loyal to his crew, King has no qualms about betraying even long-standing allies who are outside of their direct organization, especially if it is pertinent to Kaido's plans, as he lent his sword to Kaido to decapitate their ally Orochi, whom they had been friendly with for over two decades. Likewise, King also shares Kaido's streak of cruelty and ruthlessness, showing himself to be not above executing a child like Momonosuke, even demanding Sanji to hand over the boy to kill him in accordance with Kaido's New Onigashima Project. As one of Kaido's three closest associates, Kaido has great trust in King and his powers. In turn, King is very loyal to Kaido, always ready to execute missions on his behalf. When Big Mom and her children arrived at Wano Country, King was swift to attack and knock her ship into the sea, seemingly on his own initiative rather than Kaido's orders. Kaido, though seeing King as one of his confidants, did not hesitate to give the lower-ranked Tobiroppo a chance to challenge any All-Star of their choice to take their position, as the crew's hierarchy is determined by an individual's power, something King, on the other hand, did not complain about. As an All-Star of the Beasts Pirates, King holds great authority in the crew, second only to Kaido's, and is one of the crew's three strongest warriors, alongside Queen and Jack. Befitting his epithet of "Conflagration", King can generate fire in his humanoid and pteranodon forms (though whether this is a passive attribute of his or something he can actively control remains to be seen). King boasts tremendous physical strength. He easily hurled Shinobu with significant force after grabbing her by the head, repressed a Raid Suit-donning Sanji by grabbing his neck one-handed, and blocked a powerful kick from the latter using his own leg. King is also quite fast and agile, leaping across a great distance within a single moment.
