Gyro

"Crab-Hand" Gyro is the captain of a pirate crew from South Blue that was on its way to the New World before an unfortunate meeting with the New Fishman Pirates.

Appearance
Gyro is a skinny man of average height. He wears a partially unbuttoned vest underneath a short sleeved captain's coat. He wears striped pants and sandals. He carries a katana with him. He has a round head with thin mustache and small beard. On his head is what appears to be a four leaf clover. He has a bicorne tied around his neck with a string. His most distinctive feature is the giant crab claw where his left hand should be. It is made of metal with spikes coming out of the arm. This is a weapon attachment as his human arm is seen bitten off and floating next to him after being defeated by Hordy Jones.

Personality
He is a very logical man, as he knew he had to join the New Fishmen Pirates, as he could not fight them underwater, and that it was better to flee when he and his crew had the chance, rather than stay for Mermaid Cafe (as they all originally hoped) or fight against the fishmen.

Abilities and Powers
As captain, he has command over his crew. He carries a katana and is presumably skilled in using it. His crab claw is presumably a weapon as well. Gyro stated that Hordy Jones isn't the first fishman he fought against and that he overcame many dangers in the first-half of the Grand Line which indicates some level of competence.

History
At some point, he and his crew left South Blue and traveled halfway through the Grand Line and eventually made it to Fishman Island. After escaping the Kraken, he and his crew were forced to join the New Fishman Pirates under the same threat that Hammond gave to the Straw Hats. He and his crew found an opportunity to escape and took it. Gyro told his men to forget about the Mermaid Cafe and that they are never returning to Fishman Island.

Before they can get very far, they were confronted by Hordy Jones. With his jaws, the fishman gave the pirates a complete and utter defeat. Jones allowed them to live, by sending them up to the surface in a bubble, telling them that when they resurface in the New World, that will tell the people on the surface about the fishmen.
