All depends on how long Hodi and his gang stay around. I think once they're gone everything will be just peachy. Oda's placing some red herrings within the story, like Sunny already being coated making some people think Fishman Island is already close to over, but either that coating lasts super long because it was done by Den and/or Franky or the Straw Hats will be moving to a different location for part 2 of this arc. There's still a lot of plot points to cover in this arc, Van Der Decken's lineage coming into play, Shirley's prediction, that thing Van Der Decken mentioned in the flashback (Tametebako) that can age someone, Noah obviously – especially with what the King just said on the last page of the chapter, etc etc.
Awesome chapter. I love Chopper's new look and Oda incorporating Wapometal, something from a long-ago cover story, just keeps raising the likelihood for other things in cover stories to play a part in the story (like Enel and his spacey army!). Franky is obviously awesome, love that Nami has a 1-hit short-ranged attack that doesn't have to charge to add into her arsenal, but I feel what the king said at the end of this chapter is very important about "The Day That Must Come". I'd love an accurate translation of his bottom panel of King Neptune on the last spread of the chapter.
I think you are right. Hodi and his Fishmen can power up with their drugs, but i don't think they will be the main attraction
There was some mentioning of a candy factory for one of the emporers.
Candy factory and drugs who look like candy. Maybe Hodi is only the appetizer for the real challenge.
