A O Pirates

The A.O Pirates is a pirate crew led by A.O. They were a subordinate crew of the Whitebeard Pirates prior to his death.

Crew Strength
The A.O Pirates are strong enough to survive in the New World, and making a name for themselves. They were also a subordinate crew of the powerful Whitebeard Pirates, and managed to survive the Battle of Marineford.

They are, however, no match for Edward Weevil, self-proclaimed son of Whitebeard, who single-handedly defeated the entire crew.

History
At some point, the A.O Pirates became a subordinate crew of the Whitebeard Pirates, becoming part of the giant family that Edward Newgate treasures deeply.

Marineford Arc
As one of the 43 subordinate crews, the A.O Pirates set out with the Whitebeard Pirates to rescue Portgas D. Ace from execution. They set out to Marineford to fight in what would be known as the Battle of Marineford.

Ultimately, Ace was killed by Sakazuki and Whitebeard by the Blackbeard Pirates. The A.O Pirates left with the remaining survivors to give rest to fallen comrades.

Zou Arc
The A.O Pirates became the sixteenth subordinate crew of the Whitebeard Pirates to be defeated by Edward Weevil.
