Amigo Pirates

The Amigo Pirates are a group of pirates that serve under Shiki. They ride in a submarine and the majority of them dress up as mariachis. They are lead by Largo and his vice-captain Corto. Their group is welcomed to become Shiki's 51st pirate division, but are given a condition first, which is to kidnap Boss, a giant beetle that was apparently stolen from Shiki, and is now living in Little East Blue. They have all been currently arrested by the citizens of Little East Blue after being defeated by the Straw Hat Pirates.

Ship
The Amigo Pirates have a submarine as their ship. It is a green ship with intricate pattern designs, and their jolly roger painted on its front. Due to the ship being a submarine, it lacks a sail. However, the sides have paddle-wheels that allow it to move without a sail and underwater. It has a large periscope on the deck, and what appears to be gigantic harpoon launchers on the back, besides the main cabin. The back cabin has a large sombrero as a rooftop. In the end of the fight between Largo and Monkey D. Luffy, Luffy smashed Largo through the ship with a Gear Third attack.

Trivia

 * Their ship is the second in the series capable of changing into a submarine, the first being Wapol's ship. Coincidentally, the Captain Largo has a similar ability to Wapol's.
 * The regular Amigo Pirates made a mistake: they said Olé, instead of Órale (Olé is a Spanish word used in bullfighting and Órale is a common Mexican interjection).
 * The higher ranking members wear extremely large sombreros.
 * Amigo is Spanish for friend.
