The A O Pirates are strong enough to survive in the New World, making a name for themselves there. They were also a subordinate crew of the powerful Whitebeard Pirates, and managed to survive the Summit War of Marineford.
Less than three years before the Summit War of Marineford, the A O Pirates had invaded Whitebeard's territory and were still an independent crew. However, sometime afterwards they became a subordinate crew of the Whitebeard Pirates, becoming part of the giant family that Edward Newgate treasured deeply.
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 Summit War of Marineford.
