Caesar Retrieval Arc

The Caesar Retrieval Arc is the eleventh filler arc, and the second filler arc after the time skip.

In this arc, a mysterious person manages to get into the Thousand Sunny and kidnap the already-kidnapped Caesar Clown away from the Straw Hat Pirates, who are on their way to Dressrosa. However, the recently formed Heart-Hat alliance will need to get Caesar back, in order to keep up the plan to take down both Donquixote Doflamingo and Kaido. But it seems that retrieving the scientist won't be that easy, as the person has abnormal abilities.
