Arlong Pirates

The Arlong Pirates is a pirate crew led by Arlong. Every member of the crew is a fish-man. They believed they were above humans as the stronger species and looked down on them as inferior. However, after attempting to claim Orange Town, and being chased out by the civilians there with the help of a Marine Captain, Arlong realized that he couldn't take over the East Blue by himself. He proceeded to take the heads of several notable pirates from the East, and gave them to the World Government. After seeing this act, they were officially instated as a Warlord of the Sea.

Jolly Roger
Arlong's flag is that of a saw-nosed shark turned to the left with the tail curving inward. Around the shark is a semi-oval with three curves emitting from it. Behind the shark is a cross bone.
