Devil's Fruit Classes

Introduction
Devil's Fruit Classes are unofficial classifications for devil's fruits that rank the devil's fruit based on their overall fighting capability. The idea was set forth by Group5, and these classifications are used throughout Final Voyage.

Mechanics
There are five classes of devil's fruits. All factors relating to fighting, including weaknesses are taken into consideration when judging a devil's fruit. Just because a devil's fruit is in class omega doesn't mean it's weak. For example, the Heze Heze no Mi has no advantage when in combat, but it would be extremely useful if the user were a cook. The classes, listed from strongest weakest, is shown below. Paramecias can range from class omega all the way to class alpha. Logias normally rank form class gamma to class alpha. Zoans range from class beta to class omega. Mythical zoans are mostly ranked as class alpha, but a rare few are ranked as class beta.
