Things get rolling with Luffy, a lad who dreams of becoming the King of Pirates and discovering the infamous treasure One Piece. He is impulsive and never thinks anything through, and instead just jumps into situations head first, usually without knowing all of the background details. When he was a child he ate the Gum-Gum Fruit, which gives him the ability to stretch his skin like rubber. So sad he had to give up the ability to swim to get this new power. Hardly a fair trade-off when you want to live your life on a little boat in the middle of the ocean!
