Crocus

Crocus (クロッカス, Kurokkasu) is Laboon's caretaker and the overseer of the Twin Capes Lighthouse that guides ships coming down from Reverse Mountain into the Grand Line. Though he was a lighthouse keeper for most of his life, he spent three years as a doctor serving as a part of Gol D. Roger's crew.

Appearance
Crocus has an appearance based off the flower with the same name, as seen with the petals around his head.

Abilities and Powers
As a doctor, Crocus possesses expert medical knowledge. This ability allowed him to help keep Gold Roger's health stable as he traveled with him across the Grand Line, and to have made it possible to install "routes" inside Laboon's body.

Crocus is also a capable fighter. He tends to use harpoons as his choice of weapons. His strength alone is adequate of defeating large sea creatures.

Meeting the Rumbar Pirates
Fifty years before the current storyline, Crocus met the Rumbar Pirates as they entered the Grand Line through Reverse Mountain from the West Blue. As he welcomed them, he noticed that a whale, Laboon, had followed them into the Grand Line. Seeing also that their ship was banged up from their journey, Crocus agreed to allow them to stay in the Twin Capes Lighthouse while repairs were made to their ship. As their ship was being repaired, Crocus got to know the pirates personally, mainly their captain, Yorki, and musician, Brook.

After three months of repairs and partying while they were being done, the Rumbar Pirates' ship was ready to set sail again. Before parting ways, Crocus promised to take care of Laboon while they journeyed the Grand Line. Since the whale was too young then, they feared that Laboon wouldn't be able to face the dangers of the Grand Line and so entrusted Laboon to Crocus. Crocus agreed to watch over Laboon until the pirates came back from sailing around the world and came back down Reverse Mountain again. However despite the Rumbar Pirates' promise to come back after two to three years, Crocus didn't meet them again at the promised time and waited much longer.

Voyage with Gold Roger
Twenty-six years before the current storyline, Crocus met another group of pirates that came into the Grand Line through Reverse Mountain. These were the Jolly Roger Pirates and they hailed from the East Blue. Learning that their captain, Gol D. Roger, was suffering from an incurable disease, Crocus was asked by the pirates to join them as their doctor in order to help stabilize Roger's health as they journeyed the Grand Line. Wanting to find out what had happened to the Rumbar Pirates, Crocus accepted their offer and joined them.

For the next three years, Crocus journeyed as a member of the Jolly Roger Pirates from the heights of Skypiea to the depths of Fishman Island. All the while, Crocus searched for an answer to what had happened to the Rumbar Pirates as he kept Roger's health in check. As he searched, he found out from a report that stated that some of the Rumbar Pirates had tried to escape the Grand Line through the Calm Belt. Crocus believed that the entire crew had fled the Grand Line in cowardice and broken their promise to return to Laboon, unaware of their tragedies and Brook's condition.

After sailing around the world with Roger, Crocus left the crew as it disbanded. Upon returning to the cape twenty-three years before the current storyline, Crocus returned to his home in the entrance to the Grand Line and told Laboon what he learned in his travels. However, despite Crocus telling Laboon of what he believed had happened to the Rumbar Pirates, the whale wouldn't believe him and started bashing against Reverse Mountain in an attempt to rejoin his pirate comrades. Crocus, unable to stop Laboon from such a futile effort, decided to heal the scars Laboon was creating in any way he could as a doctor. Over the years as Crocus tried to convince Laboon to stop, he built an elaborate system of tunnels inside Laboon as the whale had grown too big for conventional medicines to work from the outside.

Seeing hope from another Man of D
Some twenty-three years later, Crocus met the Straw Hat Pirates after Laboon swallowed them, while Luffy came in through the main entrance on top. After defeating Miss Wednesday and Mr. 9 who had tried to kill Laboon for meat, Crocus showed the way out to them, and explained Laboon's history. Saddened by this and intrigued at the same time, Luffy eased his loss the only way he knew how: by picking a fight with Laboon. Luffy declared it as a draw, and said while he may have lost his former nakama, he now has a rival in Luffy, and will return to finish their fight after they reach end of the Grand Line. As Laboon cried tears of joy, Crocus was glad for him, and noted Luffy's similarities to that of Gol D. Roger.

Current Events
When Brook, the last survivor of the Rumbar Pirates announced that he would join the Straw Hats, Laboon gave out a triumphant wail as if to say he knew Brook was returning to him. Crocus noticed Laboon was feeling much happier.

Translation and Dub Issues
Crocus was removed from the 4Kids version of the anime, along with the entire Laboon arc. To fill up the plothole about who would explain to the Straw Hats how Log Poses and the Grand Line work out, the dub instead had Sanji do this.

While 4Kids filled in the plothole created at the time, they however unfortunately created another plothole by involving the removal of Crocus. Though it was not revealed at the time, by removing him, 4Kids removed an important piece in the story, which was how Crocus was an important part of Gold Roger's crew.
