So recently i was thinking about how weird Blackbeard's devil fruit is as a Logia. He cannot turn intangible, and even more, he feels extra pain on attacks even if he can recover. For a while (even before 1044) i had been thinking "What if BB's fruit isn't a logia, but a Zoan?" That type of fruit could potentially give him the powers he utilizes so much. But specifically, i was wondering if Zoans, especially perhaps human type zoans, may have more utility than we think
Just think. With most fruits (paramecia, and logia) attrubutes are given directly to a person. However, with Zoans, Oda seems to imply that these fruits serve somewhat as their own entities, in that they can affect a users mind and personality. Given that zoans seem to possibly be their own entity, i wonder if Zoan type fruits would be able to eat opposing types such as a Paramecia or Logia
I believe the separation here would be important. We've never heard of an inanimate object eating a Paramecia fruit, leading me to believe that between devil fruits, there might be some distinction between those of the 'living' and 'inanimate' class.
Essentially, my thought here is that anyone can eat two devil fruits, provided that they are of these opposing classes, otherwise there may be certain death.
Thus, if this theory is correct, then BB having a Zoan and a Paramecia, rather than a Logia and Paramecia, makes a lot of sense.
This theory also leads to a different theory. What if the Hito Hito fruit model: Nika is one such example of this type of fruit
My thoughts here are that, while overall Luffy's fruit as a Zoan make sense, i still find his overall powers to be strange. For example, all mythical Zoans up until now were from real-life creatures, not the OP world. So why is it that suddenly there is a Zoan exclusive to a mythical figure from OP? Does that mean that there might eventually become a Hito Hito no Mi Model: Enel? Further, how is it that Luffy has an element-based awakening, when so far we have never seen Zoans exhibit that property. It sounds more like Luffy's fruit is both Paramecia and Zoan, something which even Kaido alludes to.
My theory here, is what if a certain individual in the past. Perhaps someone named "Nika" performed this feat of mixing two devil fruits. Perhaps being some human type fruit and the original Gum Gum fruit. Then, after he died, this mixture of fruits have birth to a brand new devil fruit, exhibiting the properties of both a Zoan and Paramecia
TL;DR: What if the current classing of Devil fruits are wrong, and they are only limited to the 'Animate (Zoan)' and 'Inanimate (Paramecia and Logia)' class. And what if, on top of this, a person can eat one devil fruit of each class, leading to a hybrid fruit. This would explain both Blackbeard's and Luffy's unique devil fruits.
