Scooby-Doo! Pirates Ahoy!

20 years after his escape from Impel Down, the legendary pirate Shiki, the Golden Lion, reappears causing massive upheaval to the Marines. During his long seclusion, he was able to come up with a scheme to bring the World Government to his knees. On his way to execute the plan, Shiki crosses paths with the Straw Hat Pirates and becomes so impressed with Nami's knowledge of meteorology that he abducts her to forcedly enlist her into his crew. Luffy and the gang end up on a strange land populated with monstrous beasts as they desperately search for Shiki and Nami.

Rivaling Pirates and Spanish gold are the ingredients for this story. Blackie the pirate is the one who first hears from this shipment of gold when he encounters "Don" Pedro. He thinks of a plan to find this ship and its gold. His counter player is the vice roy of the Spanish kolony. When they visit one of the pirate settlements, they find three other pirate captains over there. One of them sells goods and prisoners from his latest capture. Don Pedro recognizes the wife of the vice roy, and Blackie buys her. However, one of the pirate captains, Skull, knows also who she is, and tries to make a deal. Blackie refuses, and Skull makes a deal with the other two pirate captains to plot against Blackie.
