Jyabura is the leader of a team he formed with Fukurou and Kumadori. He consumed the Devil Fruit Inu Inu no Mi, Model: Wolf, which grants him the ability to transform into a full wolf or a human-wolf hybrid resembling a werewolf.
He considers himself to have a fierce rivalry with Rob Lucci, though Lucci seems largely uninterested in such a rivalry. Jyabura is highly competitive and becomes furious when someone surpasses him, as seen when he was upset that Kaku had become stronger than him. He is also very superstitious, believing that if someone who has eaten a Devil Fruit gets too close to another Devil Fruit, their body will explode due to the devils confronting each other. However, Blueno explains that this belief is not true.
During combat, Jyabura often tries to deceive his opponents to catch them off guard. Initially, he chooses to fight Sogeking but switches to Sanji after realizing Sogeking is not a match for him. Sanji intervenes to save his friend from being killed by Jyabura, leading to a battle where Jyabura is ultimately defeated by Sanji's Diable Jambe technique, which penetrates Jyabura's Tekkai defense.
Jyabura is unique among his unit for mastering Tekkai Kempo, a technique that allows him to use martial arts while employing Tekkai.
