Sir Crocodile (サ ー ・ ク ロ ダ イ ル Sā Kurokodairu?) Is a former Shichibukai and leader of a secret organization, Baroque Works. He is the main antagonist of Alabasta Stories. He includes characters that often appear throughout the series.
Initially he was introduced as a Shichibukai but was later stripped of his title after trying to take over the kingdom of Alabasta and was sent to the Impel Down underwater prison. Thanks to Monkey D. Luffy, he managed to escape from Impel Down and went to Marineford to participate in the war. After that, he and Daz Bones decided to continue their adventure in the New World.
Crocodile is a tall man with a wide chest, wide shoulders, muscular arms and legs, and a sturdy neck. He had pale skin and a long neck, the black-purple hair that was kept neatly combed backwards, and was seen waving down in front of his face during battle. Crocodile has many scars that adorn its body, especially the long stitching scar above its nose which stretches along the face, and the left hand is missing, replaced by a large golden hook. Crocodile has a sad eye view, adorned with lots of wrinkles, and thin eyebrows that give a sad expression. Crocodile speaks in a deep and heavy voice, and likes to smoke cigars. The manner of dress was depicted as showing the style of the Italian mafia boss.
In its original appearance, Crocodile wore a bright orange vest with black stripes covered in a long-sleeved peach shirt, a blue scarf, dark trouser suits and polished black shoes with a gold clasp. He also wore a long, thick coat, dark gray fur (in the manga and Movie 8, shades of green) which was left to hang on his shoulders. While imprisoned at Impel Down, he wore a striped prisoner uniform, just like other prisoners, but he was allowed to keep his golden hook. After joining Luffy and Jinbe to save Ace, he wore a black shirt, green scarf, dark gray trousers, and a black coat with brown fur trim. After the Battle of Marineford, he wore clothes that resembled those in Alabasta, which consisted of a vest over a plain shirt, a scarf around his neck, a pair of pants, elegant shoes and a fur coat hanging on his back. In each appearance, he wears a single circular gold earring on his right ear, and uses a gold ring with several different gemstones on each finger. The theme of the animal is a crocodile like the meaning of the name Crocodile, its pet Bananawani and a large scar that reflects the "smile of a crocodile" in accordance with the theme.
