Van Augur (ヴァン･オーガー Van Ōgā), nicknamed "The Sonic Shooter" is the sniper of the Blackbeard Pirates and one of its original members.
Van Augur is a stoic individual compared to other members of the Blackbeard Pirates. He also shows an intellective and rational personality in the most confrontational and argumentative situations, and is rarely startled by anything that may prove a threat to him. Like most members of the Blackbeard Pirates, he has a strong loyalty to his captain and is willing to help him through his endeavors.
Van Augur first appeared in Mock Town with Blackbeard and his pirate crew. They later tried to capture the Straw Hat Pirates but they escaped from them. Van Augur and the Black Pirates later appeared on Banaro Island where they confronted by Portgas D. Ace. Ace wanted revenge on Blackbeard for betraying the Whitebeard Pirates and Van Augur observed the battle between them. After Ace's defeat, the Blackbeard Pirates turned Ace into the Marines so that Blackbeard could become apart of the Shichibukai.
Van Augur and the Blackbeard Pirates appeared in Impel Down where they were planning on recruiting the strongest pirates as their crewmates. The crew encountered Magellan, the head chief of the prison, and they were poisoned by him. They were saved by Shiliew who had an antidote to the poison. As Luffy and the other prisoners head off to Marineford to save Ace from execution, the Blackbeard Pirates resumed their plan of getting strong crew members.
After Ace's death by Akainu, the Blackbeard Pirates appeared at Marineford. Blackbeard and his crew helped Blackbeard kill off Whitebeard so that the latter could take his devil fruit. As the war raged, Shanks and his crew appeared and decided to end the conflict between the Marines and the pirates.
The Blackbeard Pirates were later seen with Jewelry Bonney and her crew on an unknown island. They left her crew behind to get arrested when they spotted Akainu on a ship coming for them.
Since the time skip, Van Augur and the Blackbeard Pirates have been going after powerful devil fruit users to enhance their crew strength.
