Wapol

Tin-Plate Wapol was once the king of the Drum Kingdom, but he became a pirate after fleeing from his country when it was attacked by Blackbeard and his crew. He later went on to become the head of a successful toy company and married Kinderella. After two years, the World Nobles gave him his own kingdom, and he became the king of the Black Drum Kingdom. Wapol was the main villain of the Drum Island Arc and the antagonist of the ninth One Piece movie. He is also the central character in the Wapol's Omnivorous Hurrah Cover Page Serial.

Wapol is an overweight man with an unusual appearance, including dark violet hair and a jaw made of tin plates, which gave him his epithet. He has a unique ability to "eat" his body and become slim using his Slim-Up technique. During the Drum Island Arc, he wore tin-plate armor, a hooded cape made from White Walkie skin, and brown thick gloves. He also had purple and orange woolen shorts, a brown belt, and thick short boots. When he was the ruler of Drum Peak, he wore a similar outfit but with a gray shirt instead of armor and gloves without fur on the upper edge. After the two-year timeskip, Wapol appeared in a different outfit as the king of the Black Drum Kingdom. He donned a different shirt and a skirt with a black pattern, paired with sharp, black pointy sandals. He still wore his hooded cape and black gloves, but his hair had turned white, and he had grown a black mustache and goatee. Wapol later contacted Morgans, the president of the World Economy News Paper, with some important information. After their meeting, Wapol went into hiding with Vivi and took refuge in Morgans' balloon. Wapol was very nervous about the possibility of the World Government finding them, and he implored Vivi to remain quiet in order to avoid attracting the attention of any Den Den Mushi that might be hidden on the balloon.
