Omatsuri

Baron Omatsuri (オマツリ男爵) is the main antagonist of the sixth One Piece movie.

Abilities and Powers
In battle, Omatsuri uses a bow and arrow, with arrows that home in on their targets. He is also capable of summoning massive arrow storms out of Lily's body, which suggests that these powers come from her.

History
The Baron was captain of the Red Arrow pirates, and they were dated back in the time when Gold Roger was still alive. The crew died in a storm, leaving Omatsuri to be washed ashore on the island, and left stranded alone. He grew bitter from the loneliness and sought to break the spirit of any pirate crew that came to his island. With Lily's help, he found that he could use her plant powers to create copies of his dead crewmates, as well as make a massive army of servants for free.

He claims to be the owner and founder of the resort on the Omatsuri Island, a recreational island in the middle of the Grand Line which the Straw Hats come to. However, he always challenges pirates who come to his island to a test called "The Trials Of Hell" before he lets them relax, in which they must take part in a variety of competitions, ostensibly to prove their strength. These games were, in reality, to see if they were suitable for feeding to his man eating plant, Lily, who grows out of his shoulder and seems to exists in a symbiotic relationship with him.

He was defeated when the father of the Teacup Pirates shoots an arrow through Lily, killing the plant, then Luffy decking Omatsuri with a powerful punch, which, needless to say, finishes him, after which he seems to have finally reunited with his crew, who didn't blame him for their deaths and just want to be a crew again like the Straw Hats. The last scene of the Baron in the movie is his goggles next to a batch of flowers growing out of the rocks.
