User blog comment:Monkey.D.Me/Is the next crewmate of Strawhat will be a Mermaid???/@comment-3202827-20101221191726

I agree! I think that it is very likely that either a mermaid or a fishman will join. A mermaid/fishman crew member would be a valuable asset to the crew because of their ability to breathe underwater and to communicate with sea creatures. Also, if a fishman joins, it will be interesting if he/she has mastered fishman karate. It is very likely that the next crew member will be female. Hopefully, this character will be introduced in the near future.
