Characters

Monkey D. Luffy
Monkey D. Luffy is the main character and is captain of the Strawhat Pirates. His other name is 'Straw Hat Luffy'. He ate a Devil Fruit called the "Gum-Gum No Mi" fruit when he was 7 years old, giving him the power to stretch like rubber. His Strawhat was given by Shanks. His older brother is Ace.

Roronoa Zoro 
Zoro was a former pirate hunter but turned into a pirate when he joined Luffy. His another name is 'Pirate Hunter Zoro'. When he was little he was the greatest warrior in his dojo, next to Kuina, the teacher's daughter, who was frustrated that girls were not able to become great swordsmen. Zoro points out that it does not matter if you are a boy or girl. They then make a promise to one another that one of them will be the greatest swordsman, or swordwoman, of all time. The very next day Kuina dies after falling down some stairs. Zoro then takes her sword so he can fulfill their dream.

Sanji 
Sanji is an amazing cook, with very good culinary skills. He is also a martial artist (who uses his feet only) that falls in love with almost every girl he sees. His other name is 'Black Leg Sanji'. His dream is to find 'The All Blue', and as a cook he values his hands greatly.
