Bluejam Pirates

Bluejam Pirates were a crew that Luffy, Ace and Sabo faced 10 years ago on Dawn Island. Ace and Sabo stole money from one of the crew members.

History
When Ace and Sabo stole money from one of the crew members of the Bluejam Pirates, Porchemy immediately set off to find the two children. Instead, he found Luffy, who was refusing to tell the pirate where the treasure was hidden. Ace and Sabo then defeated Porchemy to save Luffy. Porchemy was subsequently executed by his captain, Bluejam, for being pathetic.

Bluejam and the remainder of his crew were hired by Sabo's father to find his son, and they did so by locating the trio of children. Bluejam was ordered to kill Ace and Luffy, to ensure they will never influence Sabo again. However, the pirate captain instead incited the two into his crew, having them load explosives and gasoline into the Gray Terminal ; the Bluejam Pirates have been hired by the Nobles of the Goa kingdom to destroy the trash-filled area to make a good impression for the incoming World Nobles, and that the pirates would become Nobles if they assisted in this cleaning up. However, after leaving Ace and Luffy to die in flames, the Bluejam Pirates were left lock out of the Great Gates, having been used by the Nobles to do their dirty work, and then as scapegoats, left to burn to death in the inferno.

The crew attempted to force Ace and Luffy to reveal the location of their stolen goods so they can die with it, but were knocked out by Ace's sudden burst of Haki, and when Bluejam attempted to kill him, he was intercepted by Curly Dadan, foster mother of the boys. Ace and Dadan fought against Bluejam and defeated him, while Luffy was taken away by Magura and Dogura. As the crew had no place to run, and were rendered unconscious, they were pretty much burned to death.

Ship
The Bluejam Pirates' ship is a simple ship with a skull figurehead with teeth aligned similarly to it's captain and side mounted cannons. It was incinerated when the fire they created ran rampant, cutting off their last chance of escape.
