The Worst Generation in One Piece are a rag-rag group of pirates who have been considered to be among the most dangerous individuals who are currently seeking out the One Piece treasure, and that includes Luffy. On many occasions, Luffy and the Strawhats have run into some of the other members of this group, sometimes to butt heads, but on other occasions, to work together in order to take down a common enemy. As would come to be expected from a character designer as talented as Eiichiro Oda, each member of the Worst Generation is very unique in their appearance, coming in all sorts of shapes and sizes.
