Usopp is a great sniper but a coward who likes to lie. His other name is 'King Of Snipers: Sogeking (Sniper King)'. His weapon is a slingshot, and he has excellent aim. Luffy officially made him the crew's sniper after he had perfect aim on his first try at shooting a cannon, destroying an island in one blow (which also happened to be the island where Yosaku and Johnny were resting). His father is Yasopp, a sniper on Shank's crew.
