Poker

Poker is a Shinuchi in the Beasts Pirates.

Appearance
Poker is a rather big man with extremely long dark hair that reaches down to the floor and drapes over his eyes. He has a pair of bull-like horns on his head and his tongue, due to his Devil Fruit transformation, is forked. The only items of clothing he wears are a small, open waistcoat, a loincloth with a belt, and spiked wristbands. His legs are transformed into the beginning and end parts of a rattlesnake due to his SMILE transformation, with the middle part spanning over his head between the shoulders.

Personality
Poker cares greatly about his position in the Beasts Pirates, wanting to maintain a good reputation by stopping their opponents and even hoping to be promoted to the Tobiroppo by defeating powerful enemies.

Abilities and Powers
As a Shinuchi, Poker has authority over lower-ranking members of the Beasts Pirates.

Devil Fruit
Poker ate a Rattlesnake SMILE (ガラガラヘビの), which transformed various parts of his body into parts of a rattlesnake. His left leg became the start of the snake, complete with a sentient head, while his right leg turned into the snake's tail including the rattler at the end. The middle part of the snake starts at his left shoulder and arcs over his head before ending at his right shoulder. Additionally, his own tongue became forked, and his chin resembles a rattler. He has not been shown using this fruit in combat.

Wano Country Arc
When the Ninja-Pirate-Mink-Samurai Alliance invaded Onigashima on the day of the Fire Festival, Poker and Mizerka were stationed on the third level at the base of the stairs to the fourth level. Although Eustass Kid managed to get by them, the duo received a report that Monkey D. Luffy and his group were headed their way. Poker looked forward to taking on Luffy to keep his reputation intact after what Kid did, and to be promoted to the Tobiroppo after beating such an infamous pirate. To their surprise, however, Luffy never arrived as his allies had built a ladder to the fourth level elsewhere.

Trivia
