I jsut watched strong world for the first time, and I noticed that it was similar to the arlong arc in some ways.
 * Both villains made a promise to Nami, and didn't fulfill it
 * Both arcs focused on Nami more than others
 * Both battles end with some form of Gomu Gomu no Axe

Did anyone else find similarities here?
