Carol

Carol Masterson is Daddy Masterson's daughter, whom Usopp meets at a goggle shop, in the Loguetown Arc. She only appeared in the anime and in the Loguetown Arc (novel).

Appearance
Carol is a young, bratty and spoiled little girl with blonde hair and blue eyes. She wears a light green dress and she is always seen smiling.

Loguetown Arc
Usopp was in a shop where he wanted to buy a better pair of goggles for his adventures at sea, and, while he was trying to find his money, Carol came in and bought the goggles for her father. Then Usopp told her that he was a fearsome pirate with many followers. Carol found her father, Daddy Masterson who is a bounty hunter and told him about Usopp. After Daddy challenged Usopp to hit a weathervane with his slingshot to prove that he is Yasopp's son, he succeeded and Carol reluctantly gave the goggles to him.

Early One Piece
Carol, along with her father, are absent from the One Piece manga storyline. However, they were part of the Loguetown Arc, but were dropped so Oda could start off the adventure in Chapter 100. However, they are both featured in the Loguetown filler episodes and the Loguetown Novel. There are differences between these two versions and both Daddy and Carol have varied appearances.
