User blog comment:Blackendedsoul/Devil Fruit Limits and Physical Ability/@comment-4493594-20120122194755

Nice blog, Soul! Let's see:
 * A Zoan probably depends on the physical capabilities (mostly strength) of the user alone, depending on the kind of Zoan it is. I imagine a strong animal will enhance your physical strength more than a weak one.
 * Paramecia depend on the kind of ability they give. In Robin's case it seems to depend on concentration more than strength. So a less focused person than Robin might have more problems with that fruit. (Naturally physical strength would be beneficial) Some, such as the Sube Sube no Mi seem to have a "default strength". I cannot imagine how Alvida is supposed to train that power.
 * Paramecia that produce substances and Logia probably depend on both physical and mental strength, since a substance has both mass and quality. But it seems that even a weak person such as Mr. 3 is capable of producing considerable amounts of substance (remember Little Garden!) and strength (even a giant couldn't break out of that wax. WAX!).
