Wanyudo

Wanyudo is a Gifter in the Beasts Pirates, serving as Black Maria's weapon.

Appearance
Wanyudo has a large face with flame-shaped beard and sideburns, bushy eyebrows and a bulbous nose. Due to the effects of SMILE, the rest of his body has become that of a small pug dog.

Personality
Wanyudo is almost always seen laughing, seemingly enjoying the destruction his master Black Maria employs him for, although he appears to suffer from shortness of breath due to his constant running effort.

Abilities and Powers
Wanyudo is employed by Black Maria as her personal weapon. By running along a hamster wheel-like mechanism installed on Black Maria's polearm, Wanyudo can generate fire, increasing the destructive power of Black Maria's swings.

Despite being surrounded by fire most of the time, Wanyudo seems to be vulnerable to freezing.

Devil Fruit
Wanyudo ate a Pug SMILE (パグの) that has transformed his entire body (sans his head) into that of a pug, a small dog breed.

Trivia

 * Wanyudo is based on a yokai of the same name, which is often depicted as the disembodied head of a monk stuck inside of a flaming oxcart wheel.
 * Due to his pug SMILE, his name is also likely a pun, as the Japanese onomatopoeia for a dog's bark is wan (ワン).
 * Because of his SMILE ability, Wanyudo is also a reference to the yokai Jinmenken, a human-faced dog, which he is referred to as by Brook.
