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.

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.
