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 were all arrested by the citizens of Little East Blue after being defeated by the Straw Hat Pirates.

Crew Strength
The crew is strong enough to roam the seas of the Grand Line, and to be offered a position in the fleet of Shiki, a legendary pirate, back from Roger's era. The crew's strength seems to reside mainly in his Captain and Vice Captain, who proved themselves capable of fighting some of the Straw Hats, even if for a short while. The Amigo Pirates seem to be particularly well equipped, as they sailed on a submarine ship supplied with paddle wheels and giant harpoon launchers, and their Vice Captain displayed in combat an impressive arsenal of technological weapons. The other crewmembers were seen using guns and swords.

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". This would translate "Amigo Pirates" to "Friend Pirates", which is ironic, as they have made foes against Little East Blue and the Straw Hat Pirates. Amigo is also a pun on their captain's Devil Fruit, the Ami Ami no Mi.
