In One Piece the easiest way of gaining surreal strength in a short period of time is by eating a devil fruit. Devil fruits are divided into three main classes: Zoan, Paramecia, and Logia. Out of the three devil fruits, Logia type is generally considered the rarest type and Paramecia can be considered the most common.
So, Zoan type devil fruits lie in between those two. However, zoan type devil fruits have two different types— ancient and mythical. Mythical zoan type devil fruits even rarer than logia types and naturally they are among the strongest devil fruits. Since the series started we have come across many zoan type devil fruit users and today, we will be ranking the top ten zoan type devil fruit users.
