Corto

Colt is the Vice-Captain of the Amigo Pirates and the brother of Largo. He resembles a typical luchadore.

Abilities and Powers
Colt is seen using two large five-barreled firearms. These fire highly explosive ammunition, as seen by the amount of damage that he caused to Little East Blue with a rather short burst of fire.

He also uses bombs designed like Maracas. These are very highly explosive (much more so than his weapon's ammunition) as only a handful of them created an explosion large enough to cover one side of the island.

He has another set of gun barrels that appear out of his belt and fire at a high rate. He can also "fly" thanks to his sombrero, which can spin at high speeds and create lift, with him still attached. This combined with his "gun belt" allows him to bombard enemies with gunfire from a safe distance. Although, this won't do him any good if his ammo runs out or if his opponent also flies.

History
Colt is Largo's brother and vice-captain of the Amigo Pirates. He's the one who talks to Shiki when he offers to Largo the leadership of the 51st fleet of his pirates army, and receives the order to capture Boss, a giant beetle escaped from Shiki's collection of animals. Since when they arrive Largo is taking his siesta and cannot be awaken, Colt leads the Amigo Pirates to Little East Blue, where the beetles lives as the island protector. With his guns and bombs he attacks the villagers, destroying a lot of buildings on the island, included the copy of the Baratie restaurant. Luffy immediately attacks the pirates for protecting the island and easily manages to defeat them with the help of Sanji and Zoro. At this point, Largo awakes and intervene for helping his brother, capturing the three pirates with his Ami Ami no Mi powers and permitting to Colt to defeat a weakened Boss. When the beetle molts and frees the Straw Hats, Colt and his henchmen fight against Sanji and Zoro, but they're annihilated by the duo's strength. Colt so begins an aerial attack towards them, but is eventually defeated by Boss, who had regained his energy and attacks him with his incandescent horns. After Luffy defeats Largo and destroys the Amigos' ship, Colt is seen in a big cage in Little East Blue with his fellow pirates.

Trivia

 * Colt's name can be considered a reference to Colt's Manufacturing Company, an American firearms manufacturer, since Colt's main form of attack is gun based.
