Daddy Masterson

Daddy Masterson (also known as Daddy the Father) is a bounty hunter and father of Carol. He is introduced in the Loguetown arc. We find out that he knows Usopp's father, Yasopp, when in a dueling match. Daddy the Father had lost, but Yasopp decided to spare Daddy's life. However, this had cost Daddy his pride. Years later, he meets Usopp in Logue Town and challenges him to a duel. Usopp tries to chicken out at first but eventually comes to his senses and request a real duel with Daddy. Daddy instead issues a challenge where Usopp must hit a far off weather vane with his slingshot on the first try. Usopp not only passes the challenge but hits the impossible to see gem on the weather vane. Daddy congratulates him and Carol, his daughter, gives Usopp the goggles he tried to buy eariler.
