User blog comment:Akali95/Why? Because F*ck logic that's why!/@comment-3177613-20130330205012/@comment-4605926-20130404131106

The author creates the logic according to his choices and actions, that's right. However, once the foundations are built they shouldn't be destroyed. For instance, would you be comfortable with Luffy eating the Mera Mera fruit? Would you be comfortable with fruit users overcoming their water weakness all without a reasonable explanation?

As for Blackbeard, if you read carefully, you will see that I actually mentioned him as logical in my explanation. Refer to the "Devil Fruit" section in my blog.

About the rock logic - yes it would prove our logic wrong. However, no such case has ever occurred in the One Piece world as of yet. There are some controversial matters no doubt, hence this blog, but they were yet to be confirmed as illogical.

I would agree with you though that there might pop up things that would appear illogical, though hopefully not on purpose or to an extent which would make the readers feel the story starts to become something else. I would feel fine with expandable, though not with changeable.
