Wapol

Tin-Plate Wapol (ブリキのワポル, Buriki no Waporu) was the former ruler of the Drum Empire, originally named for the "Drum Peak," mountains which support Wapol's castle. He became a pirate after fleeing from his country when Blackbeard and his crew attacked Drum. He is the main antagonist of the Drum Island arc.

Personality and Relationships
Wapol was once prince of the region, and succeeded his father (a beloved king by the Drum people) as monarch when his father died. Wapol proved to be a spoiled and corrupt king. Before Wapol's ascension to power, the Drum Empire possessed the most numerous and skilled doctors in all of Grand Line.

He thinks he is more important then anyone else in his kingdom. He has no time nor care for political events concerning the world that do not effect his country such as Dragon and the movements of his revolutionaries. He also displays a huge lack of diplomacy skills all together in dealing with other Kings. In Japanese, he has a habit of saying "hippo" (kaba) when he means "idiot" (baka).

Abilities and Powers
He ate the Baku Baku no Mi (バクバクの実, Munch Munch Fruit), which allows him to eat virtually anything and take on its properties. Wapol uses this power many times against Monkey D. Luffy in acts such as chomping his two advisors into a single warrior, or shooting bombs from his "Munch Munch Factory" pistol arms. He even tries to eat all the weapons inside his massive armory room to turn himself into a superweapon. Though, Nami manages to steal the key from him when Wapol catches her.

Past
Wapol became king after his father (who was much loved) died. However Wapol was not the king his father had been.

Wapol exiled all of these doctors, with the exception of his personal 'Isshi-20' (20 Doctors). These doctors were forced into servitude by Wapol as he believed he could control the citizens of Drum by forcing them to personally beg him for medical treatment. Only two other doctors, Hiruluk and Kureha, managed to elude Wapol's grasp.

Wapol then laid a trap for Hiruluk who shortly after eating Tony Tony Chopper's poisoned mushroom, received a memo explaining that the 'Isshi-20' were all gravely sick. Fearing for Drum's only 'real' doctors Hiruluk traveled to Drum Castle, where he learned that the 'Isshi-20' were all fine and it had all been a scheme of Wapol's to trap him. Instead of fearing for his life, Hiruluk expressed relief that the Doctors were all fine, and in what is possibly one of the most powerful speeches in the series, he explained that it wouldn't be a knife or gun or mushroom that would kill him, he would only truly die when he was forgotten. He then drank a potion that made his body explode.

Horrified over Wapol's treatment of Hiruluk and of the country as a whole, Dalton, Wapol's Army Captain turned against him claiming that 'There is no medicine for stupidity!'. Wapol then threw him in jail for his actions.

Wapol continued to rule tyrannically over the Drum Empire until Blackbeard landed; the powerful pirate ravaged the entire kingdom and in a cowardly display Wapol abandoned his country and fled to the seas. Ever since then, Wapol had been traveling in a submersible ship with whomever decided to remain loyal to him.

During his fight with Luffy, he tries to eat all the weapons inside his massive armory room to turn himself into a super-weapon. Unfortunately, or luckily, depending on the point of view, Nami manages to steal the key from him when Wapol catches her.

In the end Luffy is able to send Wapol out of the kingdom again with a very long version of Gomu Gomu no Bazooka.

Wapol's Omnivorous Hurrah
After Wapol's second exile from his homeland, he wandered around the Grand Line in an eating spree and became fat again. He began eating various things from lamps to benches. He then transformed into them in order to eat more stuff. Soon even towns became his desert. He was practically having the time of his life, eating stuff and causing misfortune to those around him.

Eventually however, Wapol's actions caught the attention of the Marines and he was soon arrested by two Marines. Luckily, Wapol was able to escape his captors. It was then that Wapol finally realized that he was no longer a king and became deeply depressed. He then became a homeless bum whose only companion was a dog that constantly peed on him. He tried to sell matches for a living but was cruelly turned down. Eventually Wapol, having nowhere to go, settled under a bridge. Having no money at all to spend for food, all he could afford to eat was the garbage scattered around him.

While eating garbage, strange new toys were inadvertedly created by Wapol using his Baku Baku Factory technique. Among these toys, the dog that constantly peed on Wapol apparently got combined with the garbage and had obtained a google eyed box for a head. These toys eventually attracted children who were fasinated by these toys. Wapol, seeing how these toys attracted children, decided to set shop and sell these toys for a living. Eventually Wapol was able to build a proper toy shop with the earnings he got from selling toys. The stop soon in a short time became very popular. It became such a success that the demmand for his toys was almost overwhelming.

Eventually, scientists soon discovered a secret deep within Wapol's toys. It turned out that in the process of creating these toys, Wapol had also created a new type of steel. This steel, which was called Wapol steel, instantly made headline news and made Wapol an instant celebrity. With the publicity he gained, Wapol was able to expand his toy shop to great lengths. Soon Wapol had an industry on his hands. He was then able to open up an actual Baku Baku Factory which produced Wapol steel and his toys. This eventually lead to the creation of the Wapol Corporation with Wapol as the CEO.

With his wealth and hardwork, Wapol was able to marry Miss Universe. Together with his goggle eyed box headed dog and wife, Wapol was able to regain his world famous status and become even more wealthier than when he was a king.
