Buffalo is a large man with disproportionate, thin limbs. His dark hair is arranged in a propeller-like formation, and he has protruding teeth where his crew's Jolly Roger is depicted. He wears a yellow fur coat and wraps thick chains around his body, and is seen wearing a pair of strange-shaped boots.
Ten years before the takeover of Dressrosa, Buffalo's buckteeth did not yet carry the crew's symbol, and his hair was organized in more of a clover-petals formation. His clothes were darker in color than his current attire.
Buffalo is perfectly fine with that fact that Donquixote Doflamingo destroyed eight cities and all the people living there, simply for the sake of keeping Baby 5 away from her "boyfriends". He seems to be a compulsive gambler, and enjoys gambling as he asked Baby 5 for a loan of Beli2,000,000, despite just teasing asking her how high in debt she is, so he can take it to the casino after their mission. He apparently does not approve of cheaters, as a group of hustlers swindling a blind man in Acacia were noted to only have been doing so because of Buffalo's absence.
Despite his aloof and greedy personality, he also seems to be very enthusiastic, as he is almost always seen smiling. He also has a habit of saying "nnnniin" during his sentences, to imitate the sound of a propeller.
Abilities and Powers
Buffalo ate the Guru Guru no Mi, Spin-Spin Fruit, a Paramecia-class Devil Fruit which allows him to turn into a rotating man. This grants him the ability to turn his limbs into propellers, which allows him to fly across the sea and skies and, due to his large body, serve as a means of transportation, as seen when he and Baby 5 were flying over the coast of Punk Hazard, as well as spin all the propellers on his own body to create powerful gusts of wind. He can also create centripetal force by spinning his own body and use it in conjuncture with Baby 5's weaponized body to increase the damage she can inflict.
