Also known as "The Supersonic", is the sniper of the Blackbeard Pirates. His typical expression is generally emotionless. His eyebrows are almost always furrowed in what looks like a saddened expression. Like his crewmates, Augur is a heavy believer in fate. He displays very strong loyalty to Blackbeard and the rest of the crew.
As the sniper of the crew, Van Augur uses a rifle called Senriku (literally meaning "Thousand Lands"). Van Augur first appeared shooting down seagulls at a far distance from Mock Town. His riffle allows extraordinary long range shooting, when Chopper suggested to Usopp that the seagulls flying around their ship were sniped from an extremely long distance, Nami immediately disclaims it since they could not see the island Augur was on, saying it was 'impossible' for any sniper to do. Augur was even able to tell after he shot the birds that one of them did not die immediately.
He does not seem to possess Haki as when he shot at Ace, it didn't hurt him (pre-timeskip).
Trivia:
Van Augur's name and the way he was introduced, point to Roman mythology.
An augur was a priest. His main role was the practice of augury, interpreting the will of the gods by studying the flight of birds: whether they are flying in groups or alone, what noises they make as they fly, direction of flight and what kind of birds they are, much like how Augur was shooting seagulls to see which ones were fated to die painlessly.
