Kid Pirates

The Kid Pirates are an infamous and notable rookie pirate crew introduced during the Sabaody Archipelago arc during the time the Straw Hat Pirates arrived there. Like the Straw Hats, this crew has two bounties above 100,000,000. Both members have slightly higher bounties than the respective members of the Straw Hat crew.

Crewmates
The most significant fact of their appearance is that most, if not all, of the Kid Pirates have Heavy Metal-esque appearances. Also, many of them seem to wear leather in one way or another. There seems to be at least 7 members in the crew including Kid & Killer. At the auction house, they stated that they might purchase someone who caught their eye. However, it appears that nobody interested them as they never ended up bidding on anyone.

Unnamed Member
One of the more prominent members of the Kid Pirates is the one with long blue shaggy hair that almost appears to be dreadlocks, thorned tattoos on his shoulders, arms and neck, what appears to be a Glasgow smile, stitched scars at the high point of his cheeks, chin and mouth line, deep black sunken eyes and visible twin frontal veins on his forehead. He wears a dark blue open-vest tied with red straps, red pants with an armored pad over his right leg and long brown boots. Overall, he appears to be based off of the Iron Maiden's mascot, Eddie or more of a voodoo doll or zombie resembling design. He, like the rest of the crew, wears Heavy Metal themed clothes and was resistant to Silvers Rayleigh's Haki. It can be assumed that he holds high respect for Eustass Kid. This is seen when he exclaimed "Master Kid!" out of shock, when his Captain was shot in the leg by a Pacifista. He has the ability to breathe fire. It is unknown whether it stems from a devil fruit ability or not. It appears that he also uses two swords for fighting. This is seen when he stood against a Pacifista.

Crew Strength
They are most known for dealing major township destruction and citizen casualties along their route through the Grand Line and towards the New World. Furthermore, the entire crew easily survived the blast of Haki released by Silvers Rayleigh, testament to their overall hardiness. In spite of their great potency in battle and overall level-mindedness, the members of this crew display an inane sense of haughtiness.

Ship
Thier ship continues the theme of heavy metal, with a bizarre skull as part of the deck, resembling some heavy metal band's stage.
