One Piece Officially Confirms A Devil Fruit Class Stronger Than Logias

The Devil Fruits that exist in the world of One Piece can primarily be divided into three types, those being Paramecia, Zoan, and Logia. Out of all three, the Logia types are known to be the most overpowered, given that they allow the user to transform into an element or a force of nature, completely embodying that power. The Logia types were introduced first with Smoker in Chapter 97 of One Piece, which came out officially in Shueisha's Weekly Shonen Jump Issue #34 on July 19, 1999. Since then, the story has come a long way, with a lot of stronger Logia being introduced.
