Title: SMILE — The First Artificial Zoan Fruit

Description

The first SMILE fruit represents the earliest functional prototype of artificial Zoan Devil Fruits, engineered through Caesar Clown’s SAD formula and mass‑produced in the SMILE Factory. Unlike natural Zoans, SMILE fruits provide limited, unstable transformations, typically granting users a single fixed animal trait—such as limbs, heads, or appendages—rather than full hybrid or complete animal forms. While they offer enhanced strength and durability tied to the assigned animal, they also carry a severe drawback: a permanent inability to express negative emotions, forcing users into constant, uncontrollable smiling. As the foundation of all later SMILE variants, the first SMILE fruit set the blueprint for artificial Zoan abilities, combining combat utility with dangerous, irreversible side effects
