User blog comment:S.C. Amigo/Some thoughts on the Yami Yami no Mi/@comment-3242083-20110116021744

Agree with the first part. I believe that every fruit, without exception, can be useful or powerful in the right hands (especially with enough training).

Now for your own ideas, I love them. One can clearly see that you put a lot of effort into the descriptions and your examples/scenarios make them easy to picture. My favorite is Black Octopus. The only downer there is mimicry, for the very reason you mentioned as well.

Anyway, nice read/blog
