Porchemy

Porchemy was a member of the Bluejam Pirates. In Luffy's flashback, he was searching for Ace and Sabo to get back the loot that Ace had stolen from another crew member. He was a trader for his boss, captain Bluejam.

Appearance
Porchemy was a very large man with long hair, narrow eyebrow-less eyes, and a broad chest. He had tattoos on his left bicep and wore an earring on each ear. He also wore a sash around his waist and a belt over it. He wore regular pants and boots. He had been seen with a large sword.

Personality
Despite his grunt size, he was not easily fooled, as he could tell Luffy was lying. He was seemingly a ruthless pirate, due to his intolerance of Luffy and the degree of violence he used to interrogate Luffy to talk, along with Sabo's claim that he skins the heads of those he fights. He appeared to have some sense of pride for his status as a pirate, as he said that "he will quit being a pirate" if beaten by a kid.

Abilities and Powers
He appeared to have some knowledge about Devil Fruits, as he didn't appear shocked learning about Luffy's powers and simply quickly decided on a method to harm Luffy. He wields a sword and also has spiked gloves to increase the damage done from his punches. He was also strong enough to wield a very large mallet. Despite this, he was defeated by Ace and Sabo.

History
He was introduced with two fellow Bluejam pirates, one of whom had been seemingly attacked by Ace, as they heard children's voices. He caught Luffy as he was trying to escape from Ace and Sabo. Luffy blurted out Ace's name but when Porchemy asked about where the treasure was that Ace stole, Luffy responded that he did not know (in an incredibly suspicious way), but Porchemy easily saw through his lies and took Luffy away. He later tries to convince Luffy to speak via force, first unsuccessfully using a large mallet and later with spiked gloves. After he switches to a sword and is about to kill Luffy once and for all, he is attacked and defeated by Sabo and Ace, who came back to save Luffy. After his failure, his captain, disgusted by his weakness, shoots and ruthlessly kills him, saying that he's pathetic.
