User blog comment:Ichigostop/Marco's ability is unique?! yeah right../@comment-1949750-20110429013433/@comment-1949750-20110430063418

"but each devil fruit is technically as rare as any other devil fruit because they are all one of a kind"

No it isn't. Logia is much rarer than the other devil fruits. Haven't you noticed that that much less devil fruits so far revealed in the Logia than other types

Contradiction? What contradiction? You mean unique. I think you can say that idea A is more unique than idea B..... Unique also means rare and extraordinary.

I'm saying that it's the most extraordinary of all the fruits since other Zoan fruits so far don't do that and it is only DF so far that have traits from both Zoan and Logia since Marco's DF is a Zoan fruit that behaves similar to a Logia type's defense against physical attacks.

Also the manga clarifies that Mythical Zoan Devil fruit is even more rare than Logia.
