Holdem is a a Headliner of the Beast Pirates and a supporting antagonist in the Wano Country arc of One Piece.
Holdem is a large man with long brown hair, a square jaw, cat-like whiskers, and a pointed nose. He does not wear a shirt, exposing tattoos on his upper arms which resemble suns that have a wrench-shaped design inside of them. He wears dark pants, boots, gloves, and a tall dark hat with an insignia on it. His most defining features are the lion head, forelegs, and tail protruding from his waist due to his SMILE fruit. He wears a belt that encases the lion's head and forelegs.
After hearing of Gazelleman, one of the Gifters, kidnapping Tama, Holdem ordered Gazelleman to bring Tama to him. Holdem is annoyed at both Gazelleman for seemingly using so much effort for one little girl and his lion-belt Kamijiro for staring at him. Curious and suspicious of Tama's power, he decides to torture her and forcibly utilize her Devil Fruit power.
During his attempts to pull food from Tama's cheek (her Devil Fruit method of taming animals), the wrestler Urashima crashes into Holdem's hideout after being thrown into it by Luffy. Believing Luffy and his group of being associated with the thief Shutenmaru, Holdem gives orders to attack them. After Luffy rescues Tama and battles Holdem, the latter uses Kamijiro to breathe fire at his enemy to weaken him while he pulls out his sword. However, Luffy easily defeated Holdem with a Red Hawk punch. Kamijiro attempted to wake up his master as Luffy escaped with Tama.
When he woke up later, he saw Kaido in Kuri and became afraid that he would be executed for his failure, only to witness Kaido destroy the ruins of Kuri Castle instead.
Holdem later gave the order to attack Shutenmaru. Holdem was later in Okobore Town when their citizens took the blame for the recent string of thefts, and Holdem burned the town to the ground in retaliation.
