King the Conflagration is an All-Star of the Beasts Pirates and one of Kaido’s three right-hand men, the Disasters.
King is a very tall man, appearing to stand taller than the very large Jack. He wears mostly dark clothes that completely cover his body, including a mask over his face and a spiked hat with goggles on it. He also has a pair of large dark wings on his back resembling angel wings.
He is a pervert who loves torture and is shown to have a fearless side, as he had no fear in attacking the Yonko Big Mom, in spite of her being as strong as his captain Kaido.
King ate the Ryu Ryu no Mi, Model: Pteranodon, an Ancient Zoan-type Devil Fruit that allows him to transform into a full pteranodon (a large and powerful predator from the prehistoric era) and pteranodon hybrid at will.
Befitting his epithet, King is somehow able to produce fire, both in his human and pteranodon forms.
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 in his strike to throw Big Mom off.
King possessing this fruit and the “Conflagration” epithet bears resemblance to the kaiju Rodan, a pteranodon who resides in a volcano.
