Battler

Count Butler is the main antagonist of the third movie. He claims to be a genius zoologist but in reality is actually a poacher that is searching for the Crowning Treasure horns on Crown Island.He is assisted by General Hotdog and President Snake.

Appearance
Butler is a grayish skin man with purple lips. His hair is red violet and is a mohawk shaped like a musical note. Butler wears a finely dressed ensemble of clothes which include a yellow jacket. The writing on the back of his jacket reads "EVIL". This becomes a joke upon arriving as he tells Luffy and crew that he's a good guy. Butler's overall body shape is similar to those commonly possessed by other One Piece overweight characters with skinny appendages, like Foxy.

After consuming the Crowning Treasure horns, Butler bursts out from his clothes and becomes a huge yellow furred monster with the golden horns set upon his head. This form also posesses a feline like head and a bear like body with purple stripes. This stripes patterned across the shoulder portion of his body, are patterened in a way that they resemble the shape of his horns. At full height, this form is larger than Chopper's Heavy Point.

After his horns are destroyed by Luffy, Butler returns to being a human however, his post-transformation state is a shell of his former self. Upon his horns' destruction, Butler sheds his yellow fur and becomes a bald, extremely skinny human that almost resembles a mummy. Surprisingly, when he turns into this, his black pants reappear despite having been seemingly torn apart when he initially turned into a monster.

Abilities and Powers
Butler is posesses a great talent to play the violin. Combined with a specialized Wild Animal Violin that he invented himself, Butler is capable of playing a tune that is capable of controlling animals known as Horn Eaters. With this, he is able to manipulate them to attack to other animals or anyone else. Surprisingly, this tune also affects Luffy since his brainwaves are the same as an animal's.

Apart from his violin, Butler also posesses an axe cleaverly disguised as a tambourine. This particular axe was the same one he used to kill Mobambi's father and to scar Mobambi's chest.

Surprisingly, Butler is able to bite through and eat animal horns and antlers of tough keratin, without breaking his teeth. He is even able to eat the golden horns of Kirin Lion.

After becoming a monster, Butler gains a large increase in strength. He becomes so strong that he is able withstand several punches from Luffy and a direct hit in the forehead from Chopper's Kokutei Roseo, though not without bleeding as a result afterwards. Along with this immense strength in this form, Butler also posesses sharp claws and horns. His horns in particular are capable of heating up to a great degree that they can burn an opponent as well as pierce them. They are also able to send a earth shattering shockwave when Butler headbutts the ground itself. Despite all of the benefits of Butler's monster form however, it's major weak points are the golden horns themselves.

History
Upon meeting the Straw Hats, Butler claims to be a genius zoologist but is really nothing but a poacher looking for the Crowning Treasure horns on Crown Island, killing many innocent animals on his quest to find them. Butler was also responsible for the death of Mobambi's father. When he manages to get the horns and eats them, he becomes a huge hulking monster from the horn's power. However he's beaten when Luffy manages to crush his horns, turning Butler back into a human, then uses his Gomu Gomu no Bazooka to knock Butler off the island.
