 * Aisa and Nola appear again for the first time since the "Where They Are Now" cover story.
 * Chopper can now control and fight in his Monster Point form for three minutes. In addition, Chopper just needs one Rumble Ball for this form.
 * Ikaros Much removes his helmet and reveals a spear on the top of his head which he uses for a final attack.
 * The Straw Hat Pirates reveal new finishing techniques against the New Fishman Pirates officers. Usopp uses an attack called Impact Wolf, and Brook's newfound powers can even freeze blood. Franky also has the power to fire laser beams.
 * All of the New Fishman Pirates' officers have been defeated by the Straw Hats.

Trivia

 * The way Zoro dismisses Hyozou and calls him a frog at the bottom of a well is similar to when Mihawk called him the same thing during their first encounter.
